Resumen Esta revisión tuvo como objetivo exponer las relaciones entre los aditivos en la dieta de los rumiantes y las consecuencias causadas en su nutrición. Los aditivos alimentarios se utilizan en la nutrición de los rumiantes para mejorar las características productivas y/o la calidad de los productos. Hay diversas categorías de aditivos disponibles para la nutrición de rumiantes, con énfasis en antibióticos, prebióticos, probióticos, extractos de plantas y enzimas exógenas. Los antibióticos, los aceites esenciales y el quitosano actúan seleccionando bacterias sensibles y consecuentemente modulan el patrón de fermentación ruminal. Los prebióticos favorecen la microbiota, proporcionando una mayor digestión y producción de ácidos grasos volátiles. Los probióticos son microorganismos que mejoran el ambiente ruminal, lo que resulta en una mayor digestión y producción de ácidos grasos volátiles. Las enzimas exógenas actúan sinérgicamente con las enzimas secretadas por los microorganismos ruminales, además de favorecer la adhesión microbiana y colonización de las partículas, ayudan en la degradación del alimento. Los taninos, ya sea alterando el estándar de fermentación y/o modificando la microbiota ruminal, todos los aditivos son efectivos para mejorar el rendimiento animal. Sin embargo, los efectos de los aditivos sobre los productos están relacionados con la calidad de la dieta.

Abstract This review illustrates the relationships between additives in the diets of ruminants and the consequence for ruminant nutrition. Feed additives are used to improve animal perfor mance and/or the quality of the products. There are several categories of additives available for ruminant nutrition, with emphasis on antibiotics, prebiotics, probiotics, plant extracts, and exogenous enzymes. Antibiotics, essential oils, and chitosan act by selecting sensitive bacteria, consequently modulating the ruminal fermentation pattern. Prebiotics favor microbial growth, providing greater digestion and the production of volatile fatty acids. Probiotics are living microorganisms that improve the ruminal environment, promoting microbial growth and resulting in increased digestion and the production of volatile fatty acids. Exogenous enzymes act synergistically with the enzymes secreted by the ruminal microorganisms, besides favoring microbial adhesion and colonization and facilitating feed degradation. Tannins, whether altering the fermentation standard and/or modifying the ruminal microbiota population, are effective in improving animal performance. However, the effects of additives on the quality of the products are linked to diet quality.

Abstract: En | Text: En | PDF: En

Abstract Evaluate of cashew nut shell liquid (alginate-CNSL) on TBARS, physicochemical attributes and microbial growing of beef steak was investigated. Three edible coating treatments were prepared: (1) control (uncoating); (2) sodium alginate coating (no additive); and (3) active coatings of sodium alginate added cashew nut shell liquid (alginate-CNSL) at 1% into. Color indexes and water holding capacity were not affected by coating treatments. The pH of the beef samples from the control treatment increased at storage time, and the beef involved with alginate-CNSL coating maintained a pH stable. Alginate-CNSL coating promoted cooking loss lower after 3rd day of storage. Alginate-CNSL coating promoted a lower shear force decrease compared at control and sodium alginate coating. Alginate-CNSL coating reduced lipid oxidation (TBARS) and microbial growing (mesophiles and psychrophiles counts) in beef compared others treatments. Active coating from CNSL (1%) improved the beef preservation, reducing lipid oxidation and microbial growing, until the 6th day of storage stability.

Resumen Se planteó la hipótesis de que es posible que el inóculo de diferentes especies de rumiantes con capacidades digestivas diferentes que se alimentan de un determinado forraje puede mostrar diferentes utilizaciones de alimento en comparación con otras especies de rumiantes. Se evaluaron cinco gramíneas Brachiaria: B. decumbens cv. Basilisk, B. decumbens acceso D70, B. humidicola cv. Tupi, B. humidicola cv. Común, y B. ruziziensis acceso R124, en dos edades de rebrote (21 y 42 d). Se analizó la producción, el contenido bromatológico, la digestibilidad de materia seca in vitro (DMSiv) y la digestibilidad de la fibra detergente neutro in vitro (DFDNiv) utilizando inóculos bovinos u ovinos. El experimento utilizó un diseño factorial de 5 × 2 × 2 y encontró efectos significativos para la variedad de gramínea y la edad de rebrote. Además, se encontraron interacciones significativas de gramínea × edad en la materia seca, la proteína cruda, la fibra detergente neutro y la fibra detergente ácido de la muestra total y lamina de la hoja. Hubo un efecto significativo de la variedad de gramínea y la edad de la gramínea en la masa del forraje, la relación lámina de la hoja/tallo, lámina de la hoja, tallo, material senescente y crecimiento. En los ensayos de la digestibilidad in vitro, el origen del inóculo mostró un efecto significativo en algunas variedades. Debido a las diferencias en los ensayos in vitro, se recomendó el uso de inóculos específicos de las especies para las evaluaciones de alimentos según el animal al que se destina. Asimismo, B. decumbens cv. Basilisk presentó la mejor digestibilidad in vitro (DMSiv y DFDNiv) en inóculo bovino, mientras que B. humidicola cv. Tupi tuvo mejor digestibilidad in vitro (DMSiv y DFDNiv) en inóculo ovino.

Abstract It was hypothesized that it is possible that inoculum from different ruminant species with different digestive abilities feeding from a certain forage may show different feed utilizations comparing to other ruminant species. Five Brachiaria grasses were evaluated: B. decumbens cv. Basilisk, B. decumbens access D70, B. humidicola cv. Tupi, B. humidicola cv. Common, and B. ruziziensis access R124, at two regrowth ages (21 and 42 d). Production, bromatological content, in vitro dry matter digestibility (ivDMD) and in vitro neutral detergent fiber digestibility (ivNDFD) were analyzed using bovine or ovine inoculums. The experiment used a 5 × 2 × 2 factorial design and found significant effects for grass variety and regrowth age. In addition, significant interactions from grass × age on dry matter, crude protein, neutral detergent fiber and acid detergent fiber of total sample and leaf blade were found. There were significant effect of grass variety and grass age on forage mass, leaf blade/stem ratio, leaf blade, stem, senescent material and growth. In vitro digestibility assays of inoculum source showed significant effect in some varieties. Due to differences in in vitro assays, it was recommended the use of species-specific inoculums for feed evaluations according to the animal it is intended for. Also, B. decumbens cv. Basilisk presented the best in vitro digestibility (ivDMD and ivNDFD) in bovine inoculum, whereas B. humidicola cv. Tupi had better in vitro digestibility (ivDMD and ivNDFD) in ovine inoculum.

ABSTRACT The objective was to determine the optimal dehydrated passion fruit pulp replacing ground corn in diets for goat kids. We used 24 crossbred castrated goat kids with initial body weight of 26.6±0.3 kg. The experimental period was 23 days, with 15 days of adjustment and acclimatization (mostly to the installation and diet). Kids were distributed in a randomized experimental design with four treatments of 0, 80, 160, or 240 g/kg of dehydrated passion fruit residue as a supplementary inclusion in the dry matter (DM) content of the diet. The statistical model considered the fixed effect of the included amount of residue from dehydrated passion fruit. Analysis of variance was conducted using the PROC GLM of SAS. Intakes of DM and total digestible nutrients (TDN) were not affected by residue inclusion. However, neutral detergent fiber (NDF) intake increased linearly. The inclusion linearly decreased intake of ether extract (EE) and non-fibrous carbohydrates (NFC). Crude protein (CP) intake was quadratically affected, with a greater value under treatment of 160 g/kg passion fruit. Dry matter and NFC digestibility decreased linearly with the amount of passion fruit included in diet. Fecal N and total N excretion values (in g/d and %N intake) increased linearly. Nitrogen balance and N retained values showed a quadratic increase, with greater values under the 160 g/kg inclusion. Time spent ruminating, DM and NDF eating efficiency, and g DM/bolus chewed were affected quadratically by inclusion of passion fruit residue. The replacement of ground corn with dehydrated passion fruit residue at a level of 160 g/kg is recommended for diets of goat kids to improve their NDF and CP intake and their N balance without affecting DM and TDN intakes.

ABSTRACT The objective of this work was to use biometric measurements to predict carcass characteristics of lambs of the Morada Nova breed. We used 48 lambs with mean initial body weight (BW) of 15.0±0.04 kg and slaughter body weight (SBW) of 26.37±2.43 kg. The animals were weighed weekly and underwent a period of adaptation of 15 days before slaughter. The biometric measurements were obtained the day before slaughter, comprising body length, withers height, rump height, thigh length, breast width, rump width, thigh perimeter, rump perimeter, thorax perimeter, leg length, and body condition score. Additional measurements included slaughter BW and empty BW (EBW). The data recorded at slaughter comprised the weights of the viscera, carcass, and internal fat and offal. The in vivo measurements of body length were present in most of the equations for predicting the SBW, EBW, hot carcass weight (HCW), and cold carcass weight (CCW). The SBW and EBW presented a variation of approximately 9%. The variables that evaluated the carcass, HCW, and CCW demonstrated less data variation than SBW and EBW, which was probably because these measurements were obtained following evisceration and skinning, thus removing factors of more significant variation in vivo . The prediction models found in the present study varied with an R² of 0.49-0.93, indicating high levels of variation. In sum, biometric measurements can be used to predict the carcass characteristics of Morada Nova lambs with different body conditions.

ABSTRACT. The aim of this study was to evaluate the protein energetic, enzymatic and mineral profile of Nellore cows during the pregnancy, parturition and postpartum. Fifteen multiparous cows with 4 ± 1 years of age and live weight of 400 ± 50 kg were used at different stages (non-pregnant, in the initial, middle and late pregnancy, at birth, one day postpartum, 30 and 60 days postpartum). Blood collections were performed every 30 days and assayed for the following blood biomarkers: Protein (total proteins, albumin, urea and creatinine), energetic (cholesterol, triglycerides, glucose and beta hydroxybutyrate), mineral (calcium, phosphorus, magnesium) and enzymatic (alkaline phosphatase and aspartate aminotransferase). Calcium had the lowest concentrations (p < 0.05) in the initial pregnancy, while phosphorus had the highest concentration at parturition (p < 0.05). Triglycerides, glucose and beta hydroxybutyrate were influenced by the stages of pregnancy, reducing in the late pregnancy and at parturition. Glucose had a reduction in the late pregnancy and elevation in the postpartum. Beta hydroxybutyrate showed increase at the late pregnancy. Although lipomobilization occurred in the phases of higher metabolic demands in the attempt to maintain homeostatic conditions. Nellore cows did not present negative energy balance in the late pregnancy period, maintaining normal variation in blood markers throughout the experimental period.

ABSTRACT Sesamum indicum L. has the potential to be cultivated as a forage plant in hot and dry climate regions, and it can be used to increase the food security of a herd. The objective of this study was to evaluate growth, production, and chemical composition of S. indicum compared with conventional forages used for silage production. The experiment used a randomized complete block design with split-plots related to time and four replicates per treatment. The plots consisted of four treatments (Zea mays L., Helianthus annuus L., Pennisetum glaucum [L.] R. Br., and S. indicum), and the subplots were two evaluation periods (2014 and 2016 harvests). Dry forage biomass production differed among the species in the 2014 harvest with values of 25 530, 12 190, 9408, and 9250 kg ha-1 for Z. mays, S. indicum, H. annuus, and P. glaucum, respectively. Maize had a greater variation in forage production between the 2 yr, followed by S. indicum. There were higher dry matter (DM) contents (P < 0.0001) for Z. mays and S. indicum (404.5 and 251.7 g kg-1, respectively). Regarding crude protein, H. annuus and S. indicum had levels of 167.2 and 117.7 g kg-1, respectively. According to the results, it can be inferred that sesame, like millet, provides greater feeding security for ruminant herds in regions with irregular rainfall.

ABSTRACT. This study was conducted to evaluate changes in hematological biomarkers of Nellore cows at different reproductive stages. Fifteen multiparous cows with 4 ± 1 years of age and live weight of 400 ± 50 kg were used at different stages (non-pregnant, in the initial, middle and late pregnancy, at birth, one day postpartum, 30 and 60 days postpartum). Blood collections were performed every 30 days and assayed for the following hematological biomarkers: hemogram (red blood cells, globular volume, hemoglobin, mean corpuscular volume (MCV) and mean corpuscular hemoglobin concentration (MCHC)) and leukogram (total and differential counts). The erythrogram was influenced (p < 0.001) by the reproductive stages, with variation in the results obtained for the total red cell count, hemoglobin content, globular volume, MCV, MCHC and total plasma proteins. The reproductive stages influenced the leukocyte profile with variation in the total leukocyte count and in the absolute values of neutrophils, eosinophils, lymphocytes and monocytes. Hematological biomarkers of Nellore cows showed significant changes due to the physiological adjustments required in response to the metabolic requirements imposed in the final stage of pregnancy and in the beginning of lactation, ensuring the nutritional contribution in energy and oxygen transported through the blood.

RESUMO Objetivou-se determinar o impacto da inclusão datorta de licuri na dieta de cordeiros em terminação, mestiços de Santa Inês, com base na analise econômica.Utilizou-se 44 cordeiros, não-castrados, vacinados e vermifugados, com média de seis meses de idade e peso corporal médio de 21,2 kg ± 2,7 Kg. Os cordeiros foram alimentados com 40% feno de Tifton-85 e 60% de uma mistura concentrada composta por grão de milho moído, farelo de soja, premix mineral e inclusão de torta de licuri nos níveis 0; 8; 16 e 24% com base na matéria seca em substituição ao farelo de soja egrão de milho moído, com esses níveis constituindo os tratamentos, utilizando-se 11 cordeiros por tratamento em delineamento inteiramente casualizado. Os animais foram confinados por 70 dias. O menor custo operacional e consequente maior lucratividade quando se incluiu a torta de licuri até o nível de 24%. No entanto, a decisão de seu emprego na alimentação de cordeiros vai depender de seu custo no momento da utilização, considerando as possíveis variações de preços dos ingredientes utilizados para formulação das dietas e modelode produção da propriedade rural.

SUMMARY The present study endeavors to determine the impact of the inclusion of licuri tart in the diet of finishing lambs, Santa Inês mestizos, by evaluating the economic parameters. For this purpose, a total of 44 lambs, including both uncastrated as well as vaccinated and wormed lambs, with an average age of six months and a mean body weight of 21.2 kg ± 2.7 kg, were employed. Initially, the lambs were fed on the diet which consisted of 40% Tifton-85 hay and 60% of a concentrated mixture, mainly composed of ground corn grain, soybean meal, mineral premix, being further followed by the inclusion of the licuri cake at four different levels (a) 0.0, (b) 8.0,(c) 16.0, and (d) 24% with respect to the dry matter. Principally, the soybean meal and milled corn were replaced by the licuri cake with these levels, thereby constituting four treatments and 11 replicates (11 lambs per treatment) in a completely randomized design. Further, for subjecting the lambs to the above mentioned four different levels of treatment, the lambs were confined for 70 days. The analysis of various economic parameters revealed that upon including the licuri cake up to the level of 24%, the operation cost decreases, which in turn results in higher profitability. However, its cost at the time of use will eventually determine its use for feeding lambs, because of the possible price variations of the ingredients used to formulate the diets along with the model of production of the rural property.

Abstract Introduction Tinnitus and sound intolerance are frequent and subjective complaints that may have an impact on a patient's quality of life. Objective To present a review of the salient points including concepts, pathophysiology, diagnosis and approach of the patient with tinnitus and sensitivity to sounds. Methods Literature review with bibliographic survey in LILACS, SciELO, Pubmed and MEDLINE database. Articles and book chapters on tinnitus and sound sensitivity were selected. The several topics were discussed by a group of Brazilian professionals and the conclusions were described. Results The prevalence of tinnitus has increased over the years, often associated with hearing loss, metabolic factors and inadequate diet. Medical evaluation should be performed carefully to guide the request of subsidiary exams. Currently available treatments range from medications to the use of sounds with specific characteristics and meditation techniques, with variable results. Conclusion A review on tinnitus and auditory sensitivity was presented, allowing the reader a broad view of the approach to these patients, based on scientific evidence and national experience.

ABSTRACT This study aimed to evaluate the buriti oil (Mauritia flexuosa L.) inclusion levels (0, 15, 30, and 45 g kg−1 in dry matter) replacing ground corn on the feeding behavior, as well as physiological and hematological variables of crossbred lactating Anglo Nubian goats. Eight Anglo Nubian goats were used, which were distributed in a double 4 × 4 Latin square experimental design (four periods and four levels of buriti oil) replacing corn in the total dry matter. For the evaluation of feeding behavior, single animals were observed every ten minutes for 24 h on three days. Respiratory rate (RR), heart rate (HR), rectal temperature (RT), and sweating rate (SR) of the animals were evaluated in the morning (09:00 h) and in the afternoon (15:00 h). Blood samples were always taken in the morning, before feeding, by puncturing the jugular vein for the complete blood count and white blood cell count. The levels of buriti oil had no effect on feeding, rumination, idling time, water intake, defecation and urination, DM intake, feed efficiency, and rumination efficiency of DM and NDF, but had effects on NDF intake. Physiological variables (RT, SR, RR, and HR) in both periods of the day were not influenced by the inclusion of buriti oil. However, SR and RR were higher in the afternoon than in the morning. In erythrocyte, results showed that the hematocrit and mean corpuscular volume increased with the inclusion of buriti oil. Hemoglobin, red blood cell count, mean corpuscular hemoglobin concentration, and total plasma protein were not affected by the inclusion of buriti in the goat diet. The inclusion of buriti oil is recommended in up to 45 g kg−1 (DM basis) as a replacement for ground corn in diet of lactating goats without affecting the feeding behavior and physiological and hematological variables.

ABSTRACT This study aimed to assess the effects of palm kernel cake on semen quality and biochemical parameters of Santa Inês lambs. A total of 40 animals with 24.10±2.72 kg body weight and five months old were assigned in a completely randomized design into four groups and 10 replicates. The animals were subjected to four levels of palm kernel cake (0, 15, 30, and 45%) based on dry matter. The trial lasted 90 days foregone by 15 days for adaptation. Blood samples were collected every 45 days from jugular vein using vacuum tubes without anticoagulant. Total serum cholesterol, triglycerides, high-density lipoprotein, low-density lipoprotein, and very-low-density lipoprotein were assessed. Once the animals reached puberty at a mean age of 225 days, the semen samples were collected by electroejaculator once a week for three sequence weeks and assessed for volume, color, aspect, wave motion, motility, sperm concentration, sperm vigor, total of spermatozoa per ejaculate, viable spermatozoa per mL, and sperm morphology. The data were subjected to analysis of variance and followed by regression analysis. Non-parametric data were analysed by Kruskal-Wallis test. Total cholesterol, high-density lipoprotein, triglycerides, and very-low-density lipoprotein were linearly increased. There was no difference for low-density lipoprotein. Diets did not affect mass motility, sperm motility, vigor, total spermatozoa per ejaculate, viability sperm per mL, and minor and total sperm defects. Sperm concentration increased linearly. Negative quadratic effects were observed for major sperm defects. Supplementation of diets with palm kernel cake up to 45% on dry matter enhance biochemical parameters and do not impair the qualitative variables of lamb sperm.

Abstract: En | Text: En | PDF: En

his study was realized to evaluate the production of gas and volatile fatty acids when glycerin was used to replace four forage species through the use of a semi-automated technique in vitro. The experimental design included 4 treatments and 4 replications. The treatments consisted of increasing levels of glycerin (0, 30, 50 and 70%), which was used to replace the forage plants Elephant grass, sugar cane silage, corn silage and Brachiaria grass. Replacement of the Brachiaria and Elephant grasses with glycerin linearly reduced the production of methane and carbon dioxide and ammonia nitrogen and had a positive effect on forage quality (p < 0.05). With the addition of glycerin, the values for acetate concentration decreased (p < 0.05); however, when added glycerin there was increased in propionic and butyric acid concentration (p < 0.05). Substitution of forage species for glycerin by tests for semi-automatic technique in vitro reduce the production of greenhouse gases (CH4 and CO2) which reduction in energy loss, and increase volatile fatty acids propionic and butyric.

Abstract: En | Text: En | PDF: En

<sec><title>Introduction</title> Analysis of the suppression effect is a simple method to evaluate cochlear status and central auditory mechanisms and, more specifically, the medial olivocochlear system. This structure may be involved in the generation of mechanisms that cause tinnitus and in the pathophysiology of tinnitus in patients with tinnitus and normal hearing.</sec><sec><title>Objective</title> To review the literature of the etiology of tinnitus on the lights of otoacoustic emissions in patients with normal hearing.</sec><sec><title>Data Synthesis</title> Individuals with tinnitus and normal hearing have a higher prevalence of alterations in transient-evoked otoacoustic emissions and distortion-product otoacoustic emissions than normal subjects. This fact suggests that dysfunctions of the outer hair cells (OHCs) might be important in the generation of the tinnitus; however, this feature is not always present in those who have the symptoms of tinnitus.</sec><sec><title>Final Comments</title> These findings suggest that OHC dysfunction is not necessary for tinnitus development—that is, there might be mechanisms other than OHC damage in the tinnitus development. On the other hand, OHC dysfunction alone is not sufficient to cause the symptom, because a great many individuals with OHC dysfunction did not complain about tinnitus.</sec>
