Abstract Objective Pregnancy in women with lupus poses a higher risk of complications compared with the general population. The present study aimed to determine and describe the obstetric and neonatal outcomes of pregnant women with lupus. Materials and Methods We conducted an observational retrospective study of pregnant women with the diagnosis of lupus, who were selected and followed at the Maternal-Fetal Medicine Clinic of our institution between January 2013 and July 2018. We analyzed 59 pregnancies and 52 newborns, and collected data regarding sociodemographic features, the preconception period, pregnancy, childbirth, postpartum and the newborn. A descriptive analysis of the variables was performed. Results In 58% of the cases, the pregnancy was uneventful. We registered flares in 25% of the cases, preeclampsia in 3%, fetal growth restriction in 12%, gestational loss in 10%, preterm labor in 10%, postpartum complications in 20%, and small for gestational age newborns in 17% of the cases. Conclusions Most pregnancies in women with lupus have favorable obstetric and neonatal outcomes. Prenatal counseling, adequate multidisciplinary surveillance, and optimized treatment of the disease are fundamental pillars for these good results. population MaternalFetal Maternal Fetal 201 2018 5 features period childbirth newborn performed 58 cases uneventful 25 3 3% 12 12% 10 10% 20 20% 17 counseling surveillance results 2 1

Abstract This study explores the potential of the granite residue to be applied as a supplementary cementitious material. Furthermore, the efficiency of grinding methods in the improvement of the residue reactivity was also evaluated. The granite residue was collected in a facility located in Brazil and used as a Portland cement replacement with a substitution rate of 25% in mass. The residue was submitted to wet, dry and additive dry grinding methods, with several different times. The cement-based composites were characterized by quantitative X-Ray diffraction using the Rietveld's method, thermogravimetric analysis, and compressive strength. In conclusion, there was observed a higher efficiency of the wet grinding method, followed by an increase in compressive strength results as grinding time increased. Furthermore, the portlandite content was lower in the cement-based composite with granite residue, especially in the samples ground for 60, 120, and 180 minutes; a fact that summed up with other results for the pozzolanic potential of the granite residue.

Abstract Background: Ruminant feed containing animal byproduct proteins (ABPs) is prohibited in many countries due to its risk of transmitting prion diseases (PD). In most cases the entire herd is sacrificed, which causes great harm to the producer countries by preventing their exportation of ruminant derived-products. Methods: We used stable isotope ratio mass spectrometry (IRMS) of carbon (13C/12C) and nitrogen (15N/14N) to trace the animal protein in the blood of 15 buffaloes (Bubalus bubalis) divided into three experimental groups: 1 - received only vegetable protein (VP) during 117 days; 2 - received animal and vegetable protein (AVP); and 3 - received animal and vegetable protein with animal protein subsequently removed (AVPR). Groups 2 and 3 received diets containing 13.7% bovine meat and bone meal (MBM) added to a vegetable diet (from days 21-117 in the AVP group and until day 47 in the AVPR group, when MBM was removed). Results: On the 36th day, differences were detectable in the feeding profile (p <0.01) among the three experimental groups, which remained for a further 49 days (85th day). The AVPR group showed isotopic rate reversibility on the 110th day by presenting values similar to those in the control group (VP) (p> 0.05), indicating that it took 63 days to eliminate MBM in this group. Total atoms exchange (> 95%) of 13C and 15N was observed through incorporation of the diet into the AVP and AVPR groups. Conclusions: IRMS is an accurate and sensitive technique for tracing the feeding profile of ruminants through blood analysis, thus enabling investigation of ABP use.

RESUMO. Objetivou-se com o estudo avaliar os efeitos de diferentes tempos de maturação sobre as características da carne de búfalos Murrah jovens abatidos com 20-24 meses de idade (experimento I; n=10) e novilhas bubalinas Murrah abatidas com 32-36 meses de idade (experimento II; n=10), com a finalidade de determinar o melhor tempo de maturação para ambos os experimentos. As amostras do músculo longissimus thoracis foram maturadas durante 7, 14 e 21 dias (0 ± 1°C). Após esse período, foi realizada análise de colesterol, pH, perdas de peso por cocção, força de cisalhamento, índice de fragmentação miofibrilar, cor da carne e perfil de ácidos graxos. A maturação melhorou a maciez (p < 0,05), no entanto, modificou a cor da carne (p < 0,05), a qual, mesmo sem diferença entre os tratamentos para percepção subjetiva da cor (ΔE; p > 0,05), foi considerada como muito perceptível ao olho humano. Além disso, a maturação reduziu os ácidos graxos polinsaturados (p < 0,05) e não afetou os níveis de colesterol (p > 0,05) na carne de búfalos jovens e novilhas bubalinas com idade avançada. Com base nas características avaliadas, conclui-se que sete dias de maturação são suficientes para as novilhas bubalinas mais velhas, mas 21 dias de maturação são necessários para o grupo de búfalos mais jovens.

ABSTRACT. The aim of this study was to evaluate the effects of different aging times on the meat characteristics from young Murrah buffaloes slaughtered at 20-24 months of age (experiment I; n=10) and Murrah buffalo heifers slaughtered at 32-36 months of age (experiment II; n=10), with the purpose of determining the best aging time to tenderize meat from both experiments. Samples of the longissimus thoracis muscle from buffaloes slaughtered at each age were aged for 7, 14, and 21 days (0±1°C). After this period, analysis of cholesterol, pH, cooking loss, shear force, myofibrillar fragmentation index, meat color, and fatty acid profile was performed. Aging greatly improved the tenderness (p < 0.05) but caused a change in color (p < 0.05), which, even without difference between the treatments for subjective perception of the color (ΔE; p > 0.05), was considered very noticeable to the human eye. Furthermore, aging reduced the polyunsaturated fatty acids (p <0.05) and did not affect the levels of cholesterol (p > 0.05) in the meat of young buffalo and buffalo heifers of advanced age. Based on the evaluated meat characteristics, concludes that seven days of aging are sufficient for older buffalo heifers, but 21 days of aging are required for the younger male group.

Resumo:O objetivo deste trabalho foi avaliar o efeito da inclusão de simbióticos e de monensina sódica em dietas sobre o desempenho, as características de carcaça e a qualidade da carne de novilhas mestiças Angus em confinamento. Utilizou-se um delineamento inteiramente casualizado, com 64 animais distribuídos em quatro tratamentos: controle, dieta sem suplementação; dieta suplementada com simbióticos; dieta com monensina sódica; e dieta com simbióticos e monensina sódica. A dieta com monensina sódica e a dieta com simbióticos e monensina sódica proporcionaram maior ganho de peso médio diário e ganho de peso vivo total, além de melhorar a eficiência alimentar e biológica dos animais em comparação ao controle. A dieta de simbióticos, a de monensina e a de simbióticos com monensina sódica ocasionaram a redução da ingestão de matéria seca, elevaram o peso do filé da costela e os teores de lipídeos totais na carne. A dieta com simbióticos proporcionou a redução da força de cisalhamento da carne em relação ao controle. A inclusão de simbióticos, com ou sem monensina sódica, na dieta de novilhas mestiças Angus confinadas, beneficia o desempenho animal e algumas características físico-químicas da carne.

Abstract:The objective of this work was to evaluate the effect of inclusion of synbiotics and sodic monensin on the performance, carcass characteristics, and meat quality of Angus crossbred heifers on feedlot. A completely randomized block design was carried out with 64 animals distributed in four treatments: control, a diet without supplementation; a diet supplemented with synbiotics; a diet with sodic monensin; and a diet with synbiotics and sodic monensin. The diet with sodic monensin and the diet with synbiotics and sodic monensin increased the average daily gain and total live weight gain, besides improving the feed and biological efficiency of animals compared to control treatment. The diet with synbiotics, with sodic monensin, and with synbiotics and sodic monensin decreased dry matter intake, and increased the rib fillet weight (noix) and the total lipid concentration in the meat. The diet with synbiotics facilitated the reduction of meat shear force compared to control treatment. The inclusion of synbiotics, with or without sodic monensin, in diet of Angus crossbred heifers, improves animal performance on feedlot and some physicochemical characteristics of meat.

Antecedentes: las variedades de la raza Angus (Negro o Rojo) pueden exhibir un rendimiento diferente en condiciones tropicales. Objetivo: el objetivo fue evaluar las diferencias entre los grupos genéticos de bovinos Nelore x Angus F1 y F1 Nelore x Angus Colorado en cuanto al rendimiento de la canal y las características productivas en condiciones tropicales. Métodos: se utilizaron 41 novillas para evaluar los grupos genéticos con respecto al crecimiento y características de la canal. Como parámetros de rendimiento productivo se evaluó el peso vivo final y la ganancia diaria, y para características de la canal: 1) peso en canal caliente, fría y rendimiento, 2) conformación de la canal, 3) el espesor de grasa, 4) área del ojo del lomo, 5) cortabilidad y 6) carne total utilizable y cortes comerciales brasileños. Los animales fueron divididos en dos grupos y alimentados con pasto Megathyrsus maximum bajo pastoreo rotacional en tres corrales durante 28 días. Luego fueron trasladados 84 dias a un sistema de confinamiento, siendo pesados al inicio y al final del tratamiento. Todos los datos fueron sometidos a análisis de varianza con el peso vivo inicial como covariable. Resultados: hubo diferencias en el rendimiento productivo y características de la canal, en espesor de grasa dorsal y área del ojo del lomo. Sin embargo, no hubo diferencia en la conformación, el acabado, cortabilidad, la carne utilizable total y de los cortes brasileños. Conclusión: novillas F1 Nellore x Aberdeen Angus presentaron mayor rendimiento y características de la canal de crecimiento en condiciones tropicales.

Background: Angus breed strains (Black and Red) perform differently under tropical conditions. Objective: to evaluate differences among F1 Nellore x Aberdeen Angus and F1 Nellore x Red Angus regarding productive performance and carcass traits under tropical conditions. Methods: forty-one heifers were used to assess the effect of both genetic groups on productive performance and carcass traits. The performance parameters evaluated were final live body weight and average daily gain. The carcass traits were: 1) hot and cold carcass weight and cold carcass dressing percentage, 2) carcass conformation and fatting (both ranging from 1 to 5), 3) back fat thickness, 4) rib eye area, 5) cutability, and 6) total usable meat, and commercial cut yield. Animals were divided in two groups and fed Megathyrsus maximum grass in three pens for 28 days. After this period, animals were relocated in a feedlot system for 84 days, and weighed at the beginning and at the end. All data were subjected to analysis of variance with initial live weight as a covariate. Results: differences were found between groups for productive performance and carcass traits such as back fat, and rib eye area. However, no difference was observed for conformation, fatting, ease of cutability, total usable meat, and Brazilian commercial cuts. Conclusion: F1 Nellore x Aberdeen Angus heifers had increased growth performance and carcass traits under tropical conditions.

Antecedentes: animais da raça Angus podem apresentar desempenho diferente de acordó com a linha (Red Angus ou Black Angus). Objetivo: objetivou avaliar os grupos genéticos bovinos F1 Nelore x Angus Aberdeen e Nelore x Red Angus quanto ao desempenho produtivo e características de carcaça em condições tropicais. Métodos: foram utilizadas quarenta e uma novilhas para avaliar o grupo genético em relação ao desempenho de crescimento e características de carcaça. Como parâmetros de desempenho produtivo foram avaliados o peso vivo final e ganho diário e para características de carcaça: 1) peso de carcaça quente, fria e rendimento, 2) conformação da carcaça e de acabamento, 3) espessura de gordura, 4) área de olho de lombo, 5) retalhabilidade e 6) porção comestível total e rendimento de cortes comerciais brasileiros. Os animais foram divididos em dois grupos e alimentados em pastagem de Megathyrsus maximum sob pastejo rotacionado em três piquetes por 28 dias e posteriomente confinados por 84 dias, onde foram pesados no início e no final do tratamento. Todos os dados foram submetidos à análise de variância com o peso vivo inicial como covariável. Resultados: houve diferenças em desempenho produtivo e características de carcaça, a espessura de gordura subcutânea e a área de olho de lombo. No entanto, não houve diferença para conformação, acabamento, cutabilidade e rendimento dos cortes brasileiros. Conclusão: novilhas Nelore x Angus Aberdeen apresentaram melhores caracterististicas de carcaça e desempenho.

The objective of this study was to evaluate the effects of feeding cattle with isoprotein and isoenergetic diets, with and without the addition of polyclonal antibody preparation (PAP), yeasts (YST) or monensin sodium (MON) on performance, carcass characteristics and gain cost in feedlot. Ninety-five 20-month old bullocks (323.3±21.8 kg) were distributed in 25 pens. The completely randomized experimental design had a 2 × 2 + 1 factorial arrangement and the treatments were replicated 5 times. There was no effect of MON for DMI throughout the feedlot period; however, MON reduced the dry matter intake (DMI) in g/kg of BW in the first 28 days when compared with the other treatments. The gain cost decreased with MON addition in relation to the other treatments. Inclusion of YST decreased average daily gain (ADG), final body weight, hot carcass weight, carcass weight, gain to feed ratio and DMI in g/kg body weight, worsening feed conversion and increasing the gain cost in the feeding periods. Inclusion of PAP increased ADG and decreased the gain cost, besides improving feed conversion. For MON and PAP, a difference was found for kidney-pelvic fat and kidney-pelvic fat per 100 kg of hot carcass weight. For MON and YST, there was a difference in ADG, feed conversion, gain cost and carcass yield and kidney-pelvic fat per 100 kg of hot carcass. Treatment YST worsened performance in relation to the non-supplemented treatments. Feeding PAP to animals did not influence performance and carcass characteristics of bullocks in feedlot negatively. Thus, PAP shows potential to substitute MON in cattle feeding using isoprotein and isoenergetic diets.

Real-time ultrasonography (RTU) was used to measure the longissimus dorsi muscle (LM) volume in vivo and to predict the carcass composition of rabbits. For this, 63 New Zealand White × Californian rabbits with 2093±63 g live weight were used. Animals were scanned between the 6th and 7th lumbar vertebrae using an RTU equipment with a 7.5 MHz probe. Measurements of LM volume were obtianed both in vivo and on carcass. Regression equations were used for the prediction of carcass composition and LM volume using the LM volume measured obtained with RTU (LMVU) as independent variable. Carcass meat, bone and total dissectible fat weights represented 780, 164 and 56 g/kg of the reference carcass weight, respectively. Regression equations showed a strong relationship between LMVU and the correspondent volume in carcass. Furthermore, LMVU was also useful in predicting the amounts of carcass tissues. It is possible to predict LM volume in the carcass using the LM volume measured in vivo by RTU. The amount of carcass tissues can be predicted by the LM volume measured in vivo by RTU.

Abstract: En | Text: En | PDF: En

The objective of this research was to evaluate average daily gain (ADG), carcass traits, meat tenderness and profitability of keeping cattle fed different oilseeds and vitamin E in feedlot. A total of 40 Red Norte young bulls with initial average body weight of 339±15 kg were utilized. The experimental design was completely randomized in a 2 × 2 factorial arrangement. The experiment lasted 84 days and experimental diets presented soybeans or cottonseeds as lipid sources associated or not to daily supplementation of 2,500 UI vitamin E per animal. The concentrate:roughage ratio was 60:40. Diets had the same amount of nitrogen (13% CP) and ether extract (6.5%). The data were analyzed by means of statistical software SAS 9.1. Neither vitamin supplementation nor lipid source affected ADG. There was no interaction between lipid source and vitamin supplementation for the variables studied. The inclusion of cottonseed reduced the carcass yield. There was no effect of diets on hot and cold carcass weights or prime cuts. The inclusion of cottonseed reduced the backfat thickness. No effect of experimental diets on the rib-eye area was observed. There was no effect of lipid source or vitamin supplementation on meat tenderness, which was affected, however, by ageing time. Diets with soybeans presented higher cost per animal. The utilization of soybean implied reduction of the gross margin (R$ 59.17 and R$ 60.51 for diets based on soy with and without supplemental vitamin, respectively, vs. R$ 176.42 and R$ 131.79 for diets based on cottonseed). The utilization of cottonseed enables improvement of profitability of feedlot fattening, in spite of negatively affecting some carcass characteristics.

Abstract: En | Text: En | PDF: En

PURPOSE: To evaluate the outcomes and diagnostic performance of ultrasonography after a Breast Imaging Reporting and Data System (Bi-RADS) category 0 mammogram. MATERIAL AND METHODS: This retrospective study reviewed 4,384 consecutive patients who underwent a screening mammography from January 2005 to July 2006; 391 of the 4,384 exams were classified as Bi-RADS category 0. After exclusions, 241 patients received subsequent sonogram. Ultrasonography was considered diagnostic when the Bi-RADS category was changed to 2, 4, or 5, and it was considered indeterminate (Bi-RADS 3) when the results indicated that the patients should return for a mammographic follow-up. The outcomes of these patients were assessed to evaluate the diagnostic performance of ultrasonography. RESULTS: The mean age of the patients was 53.3 years (ranging from 35 to 81). Of the 241 patients, ultrasonography was considered diagnostic in 146 (60.6%) patients and indeterminate in 95 (39.4%) patients. In the diagnostic group, 111 out of 146 patients (70.2%) had a sonogram result of Bi-RADS category 2 after a 2-year follow-up without evidence of malignancy. Furthermore, 35 out of 146 patients (29.8%) had a suspicious sonogram with a result of Bi-RADS category 4. After a tissue sampling procedure, 10 patients were confirmed to have breast cancer, and 25 had benign histopathological features without any evidence of malignancy after a 2-year follow-up. The sensitivity of ultrasonography was 100%, specificity was 89.1%, and overall accuracy was 89.6%. CONCLUSIONS: Based on the degree of resolution and its diagnostic performance, ultrasonography was determined to be an excellent method for the subsequent evaluation of Bi-RADS 0 mammograms.

Os objetivos neste experimento foram gerar informações sobre a composição física e as relações músculo:osso, músculo:gordura e porção comestível:osso do lombo de ovelhas abatidas em diferentes estágios fisiológicos, além das possíveis correlações entre as variáveis avaliadas neste estudo. Foram utilizadas 21 ovelhas Santa Inês, distribuídas nos respectivos estágios fisiológicos: OL = ovelhas que permaneceram por 60 dias em lactação com seus respectivos cordeiros e abatidas um dia após o desmame dos mesmos; OSC = ovelhas que permaneceram por 60 dias em lactação com seus respectivos cordeiros e por mais um período aproximado de 30 dias sem os cordeiros e posteriormente abatidas; e ONP = ovelhas que permaneceram por 60 dias em confinamento e que não pariram durante o ano. Os percentuais de músculos e gorduras intermuscular e comestível foram semelhantes entre os estágios fisiológicos. O abate de ovelhas em diferentes estágios fisiológicos alterou a relação porção comestível:osso do lombo. Maiores proporções de gordura subcutânea corresponderam a menores quantidades de gordura intermuscular no lombo ou vice-versa.

The objectives of this paper were to generate data on physical composition and muscle:bone, muscle:fat and edible portion:bone ratios of the loin of ewes slaughtered at different physiological stages in addition to the possible correlations among the variables analyzed in this study. Twenty-one Santa Inês ewes were distributed to the following physiological stages: EL = ewes which remained in lactation for 60 days with their respective lambs and slaughtered at one day after weaning of the lambs; EWL = ewes which remained in lactation for 60 days with their respective lambs and one more period of approximately 30 days without the lambs and slaughtered afterwards; and ENP = ewes which remained in confinement for 60 days and did not give birth during the year. Muscles and edible and intermuscular fat percentages were similar among physiological stages. The slaughter of ewes at different physiological stages altered the edible portion:bone of the loin ratio. Higher proportions of subcutaneous fat correspond to lower amounts of intermuscular fat in loin or vice-versa.

Com o intuito de fornecer subsídios para programas de conservação, seleção e expansão da raça Gir no Nordeste do Brasil, objetivou-se avaliar o histórico do rebanho Gir registrado no nordeste brasileiro, com base na sua estrutura populacional e no progresso genético e fenotípico de características de desenvolvimento ponderal. Foram utilizadas informações de pedigree de animais nascidos no período de 1964 a 2006 e dados dos pesos ajustados aos 205 e 365 dias de idade de bovinos nascidos de 1978 a 2006. O progresso genético para a raça no Nordeste foi ocasionado exclusivamente pelo melhoramento ambiental. O tamanho efetivo da população reduziu a partir da década de 90, e o coeficiente de endogamia médio aumentou durante o período estudado. É imprescindível que o tamanho efetivo da raça Gir do nordeste seja ampliado e que haja maior controle de acasalamentos entre indivíduos aparentados, para prevenção da endogamia e conservação da variabilidade genética e viabilidade da raça.

This paper provides an evaluation of the population structure, phenotype and genetic trends of registered Gyr herd cattle in northeast Brazil. The study provides important baseline information for the management, conservation and potential population expansion of this economically and culturally important cattle breed. Pedigree data were analyzed for individuals born between 1964 and 2006. Body weight values were adjusted to 205 and 365 days of age for animals born between 1978 and 2006. Phenotypic change of zebu Gyr in northeast Brazil is solely due to environmental improvement. However, there is potential for artificial selection for weight gain in young cattle. Effective population size decreased during the 1990s and the average inbreeding coefficient increased during the studied period. An increase of the effective population size of Gyr in northeast Brazil is strongly recommended, along with an increase in the management of the mating process to prevent inbreeding and to maintain the genetic variability of the breed.

Objetivou-se estudar as medidas de espessura de gordura subcutânea, área de olho-de-lombo, comprimento e profundidade máxima do músculo longissimus dorsi entre a 13ª costela e 1ª vértebra lombar determinadas por ultrassom e na carcaça de ovelhas de descarte abatidas em diferentes estágios fisiológicos, além dos coeficientes de correlação e determinação das medidas avaliadas. Utilizaram-se 21 ovelhas da raça Santa Inês, distribuídas nos seguintes grupos: OL = ovelhas que permaneceram por 60 dias em lactação com seus cordeiros e foram abatidas um dia após o desmame dos mesmos; OSC = ovelhas que permaneceram por 60 dias em lactação com seus cordeiros e mais 30 dias sem os cordeiros e foram posteriormente abatidas; e ONP = ovelhas que não pariram durante o ano. O comprimento máximo do músculo longissimus dorsi obtido pelo ultrassom e na carcaça dos animais não foi influenciado pelos estágios fisiológicos. O ultrassom pode ser utilizado com razoável precisão para estimar características da carcaça de ovelhas de descarte, em particular a espessura de gordura subcutânea.

The objective of this paper was to study subcutaneous fat thickness, loin eye area, length and maximum depth measurements of the longissimus dorsi muscle between the 13th rib and the 1st lumbar vertebra determined by ultrasound examination and on the carcass of discard ewes slaughtered in different physiological stages, besides correlation and determination coefficients among measurements evaluated. It was used 21 Santa Ines ewes distributed into the following treatments: EL = ewes that remained in lactation for 60 days with their respective lambs and slaughtered one day after weaning; EWL = ewes that remained in lactation for 60 days with their respective lambs one more period of approximately 30 days without the lambs and slaughtered afterwards; and ENC = ewes that did not give birth during the year. Results showed that the maximum length of the longissimus dorsi muscle obtained by ultrasound examination and on carcass of the animals were not influenced by the experimental treatments. The ultrasound can be used with reasonable accuracy to estimate characteristics of the carcass of discard ewes, particularly the thickness of subcutaneous fat.

Objetivou-se avaliar o crescimento de novilhas de diferentes grupos genéticos no sistema de produção superprecoce. Utilizaram-se 132 novilhas dos seguintes grupos genéticos: 18 ¾ Canchim × ¼ Nelore (¾ CN); 18 ½ Canchim × ½ Nelore (½ CN); 24 Simbrasil -⅝ Simental × ⅜ Nelore; e 72 Three-cross ¼ Simental × ¼ Nelore × ½ Angus. As novilhas foram desmamadas aos 210 dias de idade, com 247,4 ± 16,5 kg de peso vivo (PV), mantidas em creep-feeding durante a fase de cria e confinadas por 132 ± 14 dias até atingirem 350 kg PV e 5 mm de gordura subcutânea, quando, então, foram abatidas. Os grupos genéticos não influenciaram o ganho de peso médio diário, porém a espessura de gordura subcutânea do dorso (EGS) e da garupa (EGG) foi maior nos animais Three-cross, que apresentaram os maiores valores iniciais (1,07 kg/dia). Não houve diferença na área de olho-de-lombo (AOL) inicial, porém a os animais Three-cross apresentaram os maiores valores iniciais. Nos animais do grupo Three-cross, a área de olho-de-lombo (AOL) final e ajustada para 100 kg de peso vivo (PV) foi inferior à observada nos demais grupos, porém o peso final foi superior ao do grupo Simbrasil, com tempo intermediário de confinamento. Ajustando-se os valores de AOL e EGG para o menor número de dias de confinamento (114 dias), animais Simbrasil apresentam maior valor de AOL final e os animais Three-cross e Simbrasil, maior EGG final.

The objective of this study was to evaluate the growth of young heifers from different genetic groups in an intensive meat production system. One hundred and thirty two heifers from four different genetics groups were used: 18 - ¾ Canchim × ¼ Nellore (¾ CN), 18 - ½ Canchim × ½ Nellore (½ CN), 24 Simbrasil - ⅝ Simmental × ⅜ Nellore (SIMB) and 72 - Three way cross ¼ Simmental × ¼ Nellore × ½ Angus. The heifers were weaned at 210 days of age with 247.4 ± 16.5 kg live weight (LW), from creep-feeding during the rearing phase and 132 ± 14 days in feedlot system. The animals were slaughtered when they reached 350 kg LW and 5 mm backfat thickness (BFT). There was no difference among the genetic groups for average daily weight gain but the three way cross heifers presented the highest values (1.07 kg/day). There were no differences for initial ribeye area (REA), but the three cross animals obtained larger values of initial backfat thickness (BFT) and initial rump fat thickness (RFT). In the animals in the three – cross group, the final ribeye area and adjusted to 100 kg live weight (LW) was lower than that observed in the other groups, but the final body weight was superior to the Simbrasil group, with intermediate feedlot time. When the REA and RFT values are fitted to the smallest number of days in feedlot (114 days), the Simbrasil animals present greater REA and the three-cross and Simbrasil higher RFT.
