1. Intake and performance of feedlot cattle fed diets based on high and low Brix sugar cane with or without calcium oxide and corn silage
The objective of this study was to evaluate low and high Brix diets, treated or not with 5 g of calcium oxide per kg of natural matter, and corn silage on intake, digestibility and performance of beef cattle. Forty cattle with initial body weight (BW) of 350 kg were used: five composed the control group, 30 were distributed into random blocks (control) and t

2. Intake, digestibility and nitrogen use efficiency in crossbred F1 Holstein × Zebu grazing cows
The objective of this study was to evaluate intake, digestibility and nitrogen (N) compounds use efficiency in F1 Holstein × Zebu grazing cows. Eighteen crossbred cows (six Holstein × Gir, six Holstein × Guzerat, and six Holstein × Nellore) were used in the experiment, constituting three experimental treatments in simple random samples, under the same fe

3. Simulation and validation of the ruminal digestion of carbohydrates in cattle from kinetic parameters obtained by in vitro gas production technique
This study aimed to validate the estimates of the ruminal degradation of total carbohydrates (TC), ruminal and total digestion of fibrous carbohydrates (FC) and microbial nitrogen flow in the abomasum evaluated by in vitro gas production technique (IVGP). Six ruminally and abomasally cannulated steers arranged in a double 3 × 3 latin square were used to mea

4. Avaliação in vitro de leguminosas taniníferas tropicais para mitigação de metano entérico / In vitro evaluation of the taninniferous tropical legumes in order to mitigate enteric methane
Animals contribute to increasing the methane concentration in the atmosphere through the fermentation of livestock manure and the fermentation in the digestive tract, e.g, enteric fermentation. The enteric fermentation of ruminants, pseudoruminants (horses, donkeys, mules) and non-ruminants produce an average of 80 Tg/year of methane and comprise 28 % of glo

5. Performance of Nellore cattle fed individualy or in group, nutrient requirements and proteic evaluation of feeds for ruminants / Desempenho de bovinos Nelore alimentados individualmente ou em grupo, exigências nutricionais e avaliação protéica de alimentos para ruminantes
The present work was developed based on four experiments. The two firsts were conducted aiming to evaluate the fecal dry matter production using total fecal collection or estimated by chromic oxide (Cr2O3), titanium dioxide (TiO2), isolated, purified and enriched lignin of Eucalyptus grandis (LIPE), indigestible neutral and acid detergent fiber (NDFi and ADF

6. Procedimentos metodológicos in situ na avaliação do teor de compostos indigestíveis em alimentos e fezes de bovinos / Methodological procedures for in situ evaluation of indigestible compounds contents in cattle feeds and feces
A presente dissertação foi elaborada com base em dois experimentos relacionados à avaliação dos teores de compostos indigestíveis em alimentos e fezes bovinas. No primeiro experimento, objetivou-se avaliar os teores de fibra em detergente neutro indigestível (FDNi) obtidos por procedimento in situ e a perda de partículas fibrosas em meio aquoso de al

7. Meal, pelleted and extruded concentrates in the fed and milk yield in dairy cows / Rações farelada, peletizada e extrusada na alimentação e produção de vacas leiteiras
This work was carried out at the dairy cows Teaching, Research and extension unit at the Department of Animal Science of the Federal University of Viçosa with the objective of evaluating: the intake and apparent digestibility of nutrients, milk production and composition, ruminal pH and ammonia, ruminal degradability of dry matter and crude protein, urea co
