Abstract The aim of the present study was to assess the carcass and meat characteristics of feedlot steers in Brazil according to genetic group through a systematic review and meta-analysis. An electronic article search was conducted at the Scielo and Google Scholar databases and data were grouped according to genetic predominance. The results were tested for heterogeneity and submitted to a normality test and F test and the means were compared by the Tukey test. Predominantly British steers were finished at a younger age, required longer confinement times and displayed lower hot carcass weights and smaller loin eye areas at slaughter. Muscle carcass percentages were higher in Continental and Synthetic steers compared to British and Zebu steers, while fat percentages were higher in British and Zebu steers compared to continental and synthetic breeds. Meat marbling was higher in British, continental and crossbreed steers compared to synthetic and zebu steers. A British steer origin allows for decreased slaughter age, although leading to reduced hot carcass weight, while a genetic Zebu predominance can produce high fat percentage carcasses. metaanalysis. metaanalysis meta analysis. analysis meta-analysis age breeds weight carcasses

Resumo O objetivo do presente estudo foi avaliar as características da carcaça e da carne de novilhos confinados no Brasil de acordo com o grupo genético por meio de uma revisão sistemática e meta-análise. Foi realizada busca eletrônica de artigos nas bases de dados Scielo e Google Acadêmico e os dados foram agrupados de acordo com a predominância genética. Os resultados foram testados quanto à heterogeneidade e submetidos ao teste de normalidade e teste F e as médias comparadas pelo teste de Tukey. Novilhos predominantemente britânicos foram terminados em idade mais jovem, necessitaram de tempos de confinamento mais longos e apresentaram menores pesos de carcaça quente e menores áreas de olho de lombo no abate. Os percentuais de carcaça muscular foram maiores nos novilhos Continentais e Sintéticos em relação aos Britânicos e Zebu, enquanto os percentuais de gordura foram maiores nos Britânicos e Zebu em comparação aos continentais e sintéticos. O marmoreio da carne foi maior nos novilhos britânicos, continentais e mestiços em relação aos novilhos sintéticos e zebuínos. A origem do novilho britânico permite menor idade de abate, embora leve à redução do peso da carcaça quente, enquanto a predominância genética do zebu pode produzir carcaças com alto percentual de gordura. metaanálise. metaanálise meta análise. análise meta-análise Tukey jovem abate zebuínos

ABSTRACT Background: In the past decades, endoscopic ultrasound has developed from a diagnostic tool to a platform for many therapeutic interventions. Various technological advancements have emerged since the last Brazilian Consensus, demanding a review and update of the recommendations based on the best scientific evidence. Methods: A group of 32 renowned echoendoscopists selected eight relevant topics to be discussed to generate clinical questions. After that, a literature review was conducted to answer these questions based on the most updated evidence. Results: Thirty-three statements were formulated and voted on by the experts to reach a consensus. The Oxford System was used to grade the level of evidence. Conclusion: There is moderate evidence to support that the needle shape, gauge, or aspiration technique does not influence the yield of endoscopic ultrasound (EUS)-guided tissue sampling of pancreatic solid lesions. There is moderate evidence to support using EUS-TTNB of the cyst wall to differentiate between mucinous and non-mucinous cystic neoplasms. There is little evidence to support the EUS-guided treatment of gastric varices. There is a high level of evidence to support that EUS-guided biliary drainage and ERCP present similar outcomes in patients with distal malignant biliary obstruction. There is a high level of evidence for using EUS to diagnose neoplastic pancreatic cysts and detect necrosis before indicating drainage. There is moderate evidence to support EUS-GE over duodenal stent for malignant gastric outlet obstruction in patients with a life expectancy higher than 2 months. There is a high level of evidence to support the use of RFA in treating both functioning and non-functioning types of NET.

RESUMO Contexto: Nas últimas décadas, a ecoendoscopia evoluiu de uma ferramenta diagnóstica para uma plataforma para diversas intervenções terapêuticas. Vários avanços tecnológicos surgiram desde o último Consenso Brasileiro, demandando uma revisão e atualização das recomendações baseadas nas melhores evidências científicas. Métodos: Um grupo de 32 ecoendoscopistas renomados selecionou oito tópicos relevantes para serem discutidos a fim de gerar questões clínicas. Em seguida, foi realizada uma revisão da literatura para responder a essas perguntas com base nas evidências mais atualizadas. Resultados: Trinta e três tópicos foram formulados e votados pelos especialistas para alcançar um consenso. O Sistema de Oxford foi utilizado para classificar o nível de evidência. Conclusão: Há evidências moderadas para sustentar que a forma da agulha, calibre ou técnica de aspiração não influenciam no rendimento da amostragem tecidual guiada por ultrassom endoscópico (USE) de lesões sólidas pancreáticas. Há evidências moderadas para sustentar o uso da biópsia transcutânea guiada por USE da parede cística para diferenciar entre neoplasias císticas mucinosas e não mucinosas. Existem poucas evidências para apoiar o tratamento guiado por USE de varizes gástricas. Há um alto nível de evidência para sustentar que a drenagem biliar guiada por USE e a CPRE apresentam resultados semelhantes em pacientes com obstrução biliar maligna distal. Há um alto nível de evidência para o uso da USE no diagnóstico de cistos pancreáticos neoplásicos e na detecção de necrose antes de indicar a drenagem. Há evidências moderadas para sustentar a preferência pela gastroenterostomia guiada por USE em relação ao stent duodenal para obstrução maligna da saída gástrica em pacientes com expectativa de vida superior a 2 meses. Há um alto nível de evidência para sustentar o uso da ablação por radiofrequência no tratamento de ambos os tipos, funcionantes e não funcionantes, de tumores neuroendócrinos.

Abstract The Indigenous Health Conferences (IHC) have been the political spaces for expressing and consolidating ideas and proposals. However, in 1993, the “First Indigenous Health Forum” was held a few months before the second IHC. With a historical approach, this paper aimed to understand the organization and impacts of this Forum in the construction of Brazilian Indigenous Health policies during the 1990s. We analyzed an unpublished set of documents organized as a Dossier by Dr. István Varga and deposited in the University of São Paulo’s library. We discuss that a strong connection with the First Indigenous Health Forum was established between the first and second IHC. The argumentative structures and proposals formulated in the First Indigenous Health Forum were reinforced during the subsequent events culminating in the Second IHC.

Abstract The pathogenic nature of infections caused by Candida spp. underscores the necessity for novel therapeutic agents. Extracts of Schinopsis brasilienses Engl are \ a promising source of agents with antifungal effects. This study aimed to assess the antifungal potential of the leaf extract of S. brasilienses. The antifungal activity was evaluated by determining the minimum inhibitory concentrations and fungicide concentrations (MIC and MFC). The antibiofilm potential was assessed by counting colony-forming units/mL. The study examined the inhibition kinetics of fungal growth and potential synergism between gallic acid or the extract and nystatin using the Checkerboard method. Cytotoxicity was evaluated through the MTT assay. The extract exhibited antifungal effect against all tested strains, with MIC and MFC ranging from 31.25–250 μg/mL. Gallic acid, the main isolated compound, displayed a MIC of 2000 μg/mL. The extract of S. brasilienses at 31.25 μg/mL inhibited the formation of biofilm by C. albicans and significantly reduced the mass of mature biofilm after 24 and 48 h (p < 0. 05). At a concentration of 125 μg/mL, the extract demonstrated significant inhibition of fungal growth after 6 hours. The combination of gallic acid or extract with nystatin did not exhibit synergistic or antagonistic effect. Furthermore, the extract did not induce cytotoxicity to a human cell line. The extract of S. brasiliensis demonstrates antifungal activity against Candida, generally exhibiting fungicidal action and capacity to inhibit biofilm formation as well as reduce mature biofilms. Additionally, the extract showed low cytotoxicity to human cells. spp effects S MFC. .

RESUMEN El síndrome de cola de caballo (SCC) es una emergencia neurológica grave resultante de la compresión de las raíces nerviosas lumbosacras, lo que puede ocasionar déficits motores, sensoriales y disfunciones esfinterianas. La intervención quirúrgica precoz es fundamental para evitar secuelas neurológicas permanentes. Tradicionalmente, la laminectomía abierta ha sido el enfoque de elección para la descompresión, pero las técnicas mínimamente invasivas, como la discectomía endoscópica, están ganando popularidad debido a su menor morbilidad, incisiones más pequeñas y recuperación más rápida. Este estudio presenta tres casos de pacientes con SCC tratados con discectomía endoscópica. Dos de los casos fueron causados por una hernia discal extrusa volumétrica y uno por un quiste facetario intracanal. La intensidad del dolor se evaluó mediante la Escala Visual Analógica (EVA) y la discapacidad funcional mediante el Oswestry Disability Index (ODI) en el período preoperatorio y en los seguimientos de 1, 6 y 12 meses. Los tres pacientes mostraron una mejora significativa en los síntomas, con reducción del dolor y mejora funcional. A los 12 meses, los pacientes mantuvieron su recuperación funcional y neurológica sin complicaciones reportadas. La técnica endoscópica demostró ser un método seguro y eficaz para el tratamiento del SCC en estos casos, ofreciendo una recuperación precoz y menos complicaciones postoperatorias.

RESUMO A Síndrome da Cauda Equina (SCE) é uma emergência neurológica grave resultante da compressão das raízes nervosas lombossacrais, podendo ocasionar déficits motores, sensoriais e disfunções esfincterianas. A intervenção cirúrgica precoce é fundamental para evitar sequelas neurológicas permanentes. Tradicionalmente, a laminectomia aberta tem sido a abordagem de escolha para descompressão, mas as técnicas minimamente invasivas, como a discectomia endoscópica, estão ganhando espaço por apresentarem menor morbidade, incisões menores e recuperação mais rápida. Este estudo relata três casos de pacientes com SCE tratados com discectomia endoscópica. Dois dos casos foram causados por hérnia discal extrusa volumosa e um por cisto facetário intracanal. A intensidade da dor foi avaliada pela Escala Visual Analógica (EVA) e a incapacidade funcional pelo Oswestry Disability Index (ODI) no período pré-operatório e em seguimentos de 1, 6 e 12 meses. Os três pacientes apresentaram melhora significativa dos sintomas, com redução da dor e melhora funcional. Aos 12 meses, os pacientes mantiveram a recuperação funcional e neurológica, sem complicações relatadas. A técnica endoscópica mostrou-se uma técnica segura e eficaz no tratamento da SCE nos casos relatados, oferecendo recuperação precoce e menos complicações pós-operatórias.

ABSTRACT Cauda Equina Syndrome (CES) is a severe neurological emergency resulting from the compression of the lumbosacral nerve roots, potentially causing motor and sensory deficits, as well as sphincter dysfunctions. Early surgical intervention is essential to prevent permanent neurological sequelae. Traditionally, open laminectomy has been the treatment of choice for decompression. Still, minimally invasive techniques, such as endoscopic discectomy, are gaining popularity due to lower morbidity, smaller incisions, and faster recovery. This study reports three cases of patients with CES treated with endoscopic discectomy. Two cases were caused by a large, extruded disc herniation and one by an intracanal facet cyst. Pain intensity was assessed using the Visual Analog Scale (VAS), and functional disability was measured with the Oswestry Disability Index (ODI) in the preoperative period and at follow-ups of 1, 6, and 12 months. All three patients showed significant improvement in symptoms, with pain reduction and functional improvement. At 12 months, the patients maintained their functional and neurological recovery without reported complications. The endoscopic technique proved to be a safe and effective method for treating CES in these cases, offering early recovery and fewer postoperative complications. Future studies with larger populations are needed to validate these findings. Level of Evidence IV; Case Report.

Resumen El uso de mezclas asfálticas en frío ha despertado el interés en los últimos años debido a que es una técnica que reduce el uso de combustibles y con ello, la huella de carbono en la construcción y mantenimiento de pavimentos, sin embargo, se ha limitado su uso en aplicaciones de bacheo y pavimentos de bajo tránsito, debido a que estas mezclas presentan baja resistencia a edad temprana y altas cantidades de vacíos. El objetivo de la presente investigación fue el desarrollo de una mezcla fría con sustitución del relleno mineral por rellenos cementantes ternarios que en conjunto forman productos de hidratación y brindan mayor resistencia en presencia de agua. Los rellenos cementantes ternarios están compuestos por escoria de alto horno granulada (EGAH), ceniza volante (CV) y un activador alcalino, ya sea cemento Portland (CP) o hidróxido de calcio (cal). A fin de comparar cuál de estos activadores brinda un mayor desempeño se prepararon distintas mezclas con sustitución parcial y total, para evaluar en tres condiciones de curado y observar el comportamiento de las mezclas en presencia de agua. Se comprobó que la sustitución con ambos tipos de rellenos cementantes reduce significativamente los efectos de la humedad a edad temprana. Para la condición de curado de 3 días a 25 °C, la muestra de referencia obtuvo una pérdida de estabilidad de 30,78 %, las muestras con CP de 7,61 y 7,56 %, y las de cal con 13,83 y 16,39 %, por lo que se observa que tienen una menor pérdida de estabilidad en todos los casos, este mismo patrón se mantiene en el tiempo.

Abstract The use of cold asphalt mixtures has aroused interest in recent years because it is a technique that reduces the use of fuels and thus the carbon footprint in the construction and maintenance of pavements, however its use has been limited in patching applications and low-traffic pavements, however, these mixtures have low resistance at an early age and high amounts of voids. The objective of this research was the development of a cold mixture with replacement of the mineral filler with ternary cementitious fillers that together form hydration products and provide greater resistance in the presence of water. The ternary cementitious fillers are composed of granulated blast furnace slag (EGAH), fly ash (CV) and an alkaline activator, Portland cement (CP) or calcium hydroxide (lime), in order to compare which of these activators provides greater performance different mixtures were prepared with partial and total substitution, to evaluate in three curing conditions and observe the behavior of the mixtures in the presence of water. It was proven that replacement with both types of cementitious fillers significantly reduces the effects of moisture at an early age. For the curing condition of 3 days at 25 °C, the reference sample obtained a loss of stability of 30,78 %, the samples with CP of 7,61 and 7,56 %, and those of lime with 13,83 and 16,39 %, have a lower loss of stability in all cases, this same pattern is maintained over time.

Abstract Periapical lesions (PL) of endodontic origin are one of the most common pathological conditions that affect peri-radicular tissues. The main objective of this study was to evaluate the amount and species of microorganisms isolated from necrotic pulps, establish a correlation between these and the size of periapical lesions, and how the amount and species of microorganisms decreased with non-surgical root canal treatment. Twenty-seven patients with a clinical diagnosis of dental pulp necrosis and chronic periapical lesions were selected; a Cone Beam Computed Tomography (CBCT) and microbial samples of the root canal system were taken previous to a disinfection protocol, a post-instrumentation/ disinfection protocol, and a post-medication placement. Samples were processed for colony-forming unit (CFU) counting, Gram staining technique, and bacterial identification by the API-20 Strep/API-20A system. The API system identified 21 species of microorganisms in the pre-instrumentation samples, 11 species in the post-instrumentation samples, and 11 in the post-medication samples. There was a correlation coefficient of 0.598% between the initial size of the lesion and the number of bacteria, with a coefficient of determination up to 35.7%, a correlation coefficient of 0.486% and a determination coefficient of 23.6% between the size of the periapical lesion and the number of CFUs. This study contributes to the knowledge of the amount and species of microorganisms isolated and identified from necrotic pulps, establishes a correlation between the amount and species of microorganisms and the size of the periapical lesions, and shows how the decrease of microorganisms contributes to the healing of PL, corroborating the importance of an adequate disinfection protocol.

Resumen Las lesiones periapicales (LP) de origen endodóncico son la condición patológica más común que afectan los tejidos perirradiculares. El objetivo principal de este estudio es evaluar la cantidad y especie de bacterias aisladas de pulpas necróticas, correlacionar la cantidad y especies bacterianas con el tamaño de la lesión, y cómo disminuyen la cantidad y especies de microorganismos con el tratamiento de conductos. A 27 pacientes con diagnóstico de necrosis pulpar y lesión periapical crónica detectada con CBCT se les tomaron muestras microbianas del sistema de conductos antes y después del protocolo de desinfección y de la medicación intraconducto. Las muestras se procesaron para el recuento de unidades de formación de colonias (UFC), tinción de Gram e identificación mediante el sistema API-20 Strep/API-20A. Se identificaron 21 especies en las muestras pre-instrumentación, 11 en las muestras post-instrumentación y 11 en las muestras post-medicación; se observó un coeficiente de correlación del 0,598% entre el tamaño inicial de la lesión y la cantidad de bacterias, con un coeficiente de determinación hasta el 35,7%, un coeficiente de correlación del 0,486% y un coeficiente de determinación del 23,6% entre el tamaño de la lesión periapical y el número de UFCs. Este estudio contribuye al conocimiento sobre la cantidad y especies de microorganismos aislados e identificados a partir de pulpas necróticas, establece una correlación entre la cantidad y especies de microorganismos y el tamaño de las lesiones periapicales y exhibe cómo la disminución de microorganismos contribuye a la curación de LP, corroborando la importancia de un adecuado protocolo de desinfección.

RESUMO: Objetivou-se mensurar o efeito da associação entre caracteres agronômicos relacionados à produtividade de grãos de canola cultivada em diferentes épocas de semeadura, através da análise de trilha. Assim como também objetivou-se obter um método para predizer o teor de óleo nos grãos, ajustando um modelo multivariado através da análise por espectroscopia na região do infravermelho próximo. O experimento foi conduzido em campo, utilizando-se o delineamento de blocos ao acaso, em parcelas subdivididas no tempo, sendo quatro parcelas (épocas de semeadura) e seis subparcelas (híbridos de canola), com quatro repetições. Em cada híbrido foram realizadas observações fenológicas e determinada a produtividade de grãos. Os dados foram submetidos à análise de variância em ambiente R pelo teste F, a cinco de probabilidade. O teor de óleo nos grãos foi determinado pelo método químico tradicional, e com base na assinatura espectral no infravermelho próximo de amostras dos grãos foi estabelecida regressão dos mínimos quadrados parciais (PLS-R) para estimar o teor de óleo nos grãos de canola. As épocas de semeadura influenciaram os componentes de produção e o teor de óleo dos grãos de todos híbridos. Os caracteres número de grãos em cinco plantas (0,6857) e altura (0,4943) apresentaram maiores estimativas de correlação positiva com a produtividade de grãos, assim como os maiores valores de efeito direto positivo sobre a produtividade, 0,2494 e 0,1595 respectivamente. Entretanto, o ciclo total (-0,7848), juntamente com dias em florescimento (-0,4520) apresentou correlação significativa negativa com a produtividade. A técnica NIR associada à PLS-R foi capaz de predizer o teor de óleo nos grãos, resultando em bons modelos preditivos (R2 de 0,86 e RMSE de 1,56 na validação externa) que podem ser usados com sucesso na análise da qualidade das amostras após colheita e nos programas de melhoramento genético.

ABSTRACT: This study measured the effect of the association between agronomic traits related to the yield of canola grains grown at different sowing dates through path analysis. Another objective was to obtain a method to predict the oil content in the grains, fitting a multivariate model through near-infrared (NIR) spectroscopy analysis. The experiment was conducted in the field using a randomized block design in plots subdivided by time, with four plots (sowing dates), six subplots (canola hybrids), and four replicates. In each hybrid, phenological observations were performed, and the grain yield was determined. The data were subjected to analysis of variance in the R environment using the F test at 5% probability. The oil content in the grains was determined by the traditional chemical method, and based on the NIR spectral signature of the grain samples, partial least squares regression (PLS-R) was established to estimate the oil content in the canola grains. The sowing dates influenced the production components and oil content of the grains of all hybrids. The trait number of grains in five plants (0.6857) and their height (0.4943) had greater estimates of positive correlations with grain yield, as well as higher values of positive direct effects on yield (0.2494 and 0.1595, respectively). The NIR technique combined with PLS-R was able to predict the oil content in the grains, resulting in good predictive models (R2 of 0.86 and root mean square error (RMSE) of 1.56 in external validation).

Resumo O objetivo deste trabalho foi avaliar, por meio de meta-análise, o impacto da espessura de gordura subcutânea nas características qualitativas de carne bovina. Foram utilizados dados combinados de 13 estudos, compreendendo 245 carcaças de bovinos machos abatidos no Brasil. O tamanho do efeito para todos os parâmetros foi calculado como diferença média ou diferença média padronizada, a 95% de probabilidade. A meta-análise de efeitos aleatórios e fixos foi realizada quando I2>50% e I2<50%, respectivamente, para cada indicador separadamente, com as médias para espessura de gordura classificadas nos grupos “controle” (3–6 mm), “baixo” (<3 mm) e “alto” (>6 mm). As carcaças do grupo “alto” apresentaram maior deposição de gordura intramuscular, enquanto as do grupo “baixo” apresentaram deposição de gordura intramuscular semelhante à do controle. Quando a espessura da gordura estava abaixo do limite recomendado de 3 mm, a força de cisalhamento aumentou. Valores de espessura de gordura subcutânea maiores que 6 mm induziram mudança positiva na percepção de maciez pelo painel de avaliadores. As carcaças bovinas com espessura de gordura subcutânea superior a 6 mm tendem a acumular maior teor de gordura intramuscular e são mais macias para aceitação do consumidor. As carcaças com espessura de gordura inferior a 3 mm produzem carne mais dura. avaliar metaanálise, metaanálise meta análise, análise bovina 1 estudos 24 Brasil padronizada 95 probabilidade I250 I I2 50 I2>50 I2<50% respectivamente separadamente controle “controle 3–6 36 (3– , baixo “baixo <3 (< alto “alto >6 (> mm. . aumentou avaliadores consumidor dura 2 9 I25 5 I2>5 I2<50 3– (3 < ( > I2> I2<5 I2<

Abstract The objective of this work was to evaluate, through meta-analysis, the impact of subcutaneous fat thickness on beef qualitative traits. Combined data from 13 studies were used, comprising 245 carcasses of male bovines slaughtered in Brazil. Effect size for all parameters was calculated as mean difference or standardized mean difference, at 95% probability. The meta-analysis of random and fixed effects was carried out when I2>50% and I2<50%, respectively, for each indicator separately, with means for fat thickness, classified in the “control” (3–6 mm), “low” (<3 mm), and “high” (>6 mm) groups. Carcasses in the “high” group showed greater intramuscular fat deposition, whereas those in the “low” group presented an intramuscular fat deposition similar to that of the control. When the fat thickness was below the recommended threshold of 3 mm, shear force increased. Subcutaneous fat thickness values greater than 6 mm induced a positive change in the perception of tenderness by the panel of evaluators. Beef carcasses with a subcutaneous fat thickness over 6 mm tend to accumulate more intramuscular fat content and are tenderer for consumers’ acceptance. Carcasses with a fat thickness less than 3 mm produce tougher meat. evaluate metaanalysis, metaanalysis meta analysis, analysis traits 1 used 24 Brazil 95 probability I250 I I2 50 I2>50 I2<50% respectively separately control “control 3–6 36 (3– , low “low <3 (< high “high >6 (> groups increased evaluators consumers acceptance meat 2 9 I25 5 I2>5 I2<50 3– (3 < ( > I2> I2<5 I2<

■ ABSTRACT Introduction: The oncological reconstruction of extensive defects in the head and neck requires the plastic surgeon to make a difficult decision between the use of free flaps and pedicled flaps. The supraclavicular flap is one of the main examples of a pedicled flap, being versatile, with a thin thickness and similar color to the region to be reconstructed. Method: A retrospective study was carried out by collecting data from medical records of patients admitted to the Cancer Institute of the State of São Paulo between December 2010 and March 2020. Results: Among the 62 patients reconstructed with a supraclavicular flap, 37 were male and 25 female. Fifty-eight patients (93.5%) had some associated comorbidity. In total, 27 complications related to the flap (43.5%) were recorded, 5 of which were total necrosis (8%). Conclusion: The supraclavicular flap plays an important role in head and neck oncological reconstructions and should be considered as an option in patients who are poor candidates for microsurgical flaps.

ABSTRACT Determining what and how much each environmental factor affects pregnancy is crucial to the sustainability and management of beef cow herds. The study evaluated through logistic regression the effect of environmental variables on the increase or reduction in the pregnancy rate of beef cows. The average pregnancy rate in the cows was 73 %, with an average age for the herd of 3.7 years. An increase in age of one year represented a 30 % increase in pregnancy, while a reduction of one year reduced the odds of pregnancy in the cows by 23 %. During the lactation period, an extra seven days’ lactation reduced the odds of pregnancy by 12 %. For every seven days that weaning was brought forward, the cows’ pregnancy odds increased by 14 %. An increase of 0.1 kg in average daily gain represented an increase of 17 % and 15 % in the odds of pregnancy during the first 60 days post-partum and 60 days to the end of the reproductive period. On the other hand, the loss of 0.1 kg in average daily gain resulted in a 14 % and 13 % reduction in the cows’ pregnancy odds, respectively. Factors such as age, the precocity of calving in the calving season, the time the calf remains with the cow and better performance in cows between calving and the end of the mating are strategies that increase the chances of pregnancy in beef cows. herds 7 37 3 3. years 2 period 1 forward 01 0 0. 6 postpartum post partum hand respectively season

Abstract Potential variables for the reproductive success of beef cows were evaluated. Included in the model were the age of the cow at calving; the interval between the Julian calving date and the end of the breeding season; the body weight and conditions at calving, at 75 days post-partum and at the end of the breeding season; and the mean daily variation in weight between these dates. Logistic regression was used in the analysis, with the parameters evaluated using the odds ratio statistic, estimating the chance of pregnancy. The mean rate of pregnancy was 84% and 55% for early and late-weaned cows, respectively. For early weaned cows, the regression variables were the Julian calving date, age of the cow, weight gain from calving to 75 days post-partum, and from 75 days post-partum to the end of the reproductive period. For late-weaned cows, there were only two regression variables, weight at calving and weight gain from calving to the end of the reproductive period. For every year above the average age of the herd, early weaned cows have an 80.9% greater chance of pregnancy, while a reduction of one year reduces the chance of pregnancy by 44.7%. In early weaned cows, every seven days after the mean Julian calving date reduces the chances of pregnancy by 22.6%, whereas every seven days before the mean calving date increases pregnancy by 29.2%. Greater gains in cow body weight, from calving to the end of the reproductive period, determine a greater probability of pregnancy. season 7 postpartum post partum dates analysis statistic 84 55 lateweaned late respectively postpartum, partum, period herd 809 80 9 80.9 447 44 44.7% 226 22 6 22.6% 292 29 2 29.2% 8 5 80. 4 44.7 22.6 29.2 44. 22. 29.
