13. Microbial populations and fermentation profile in tropical grass silages and performance of beef cattle fed diets containing mombaça grass silages / Populações microbianas e perfil fermentativo em silagens de capins tropicais e desempenho de bovinos de corte alimentados com dietas contendo silagens de capim-mombaça
This study consisted of five experiments. The first evaluated the microbial populations, fermentation profile and chemical composition of silages of signal grass at different regrowth ages (30, 40, 50, 60 and 70 days) in six fermentation periods (1, 3, 7, 14, 28 and 56 days). There was increase in lactic acid bacteria (LAB) and decrease in enterobacteria (EN

14. 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

15. Effect of additives on feed quality and nutritional value of sugarcane silage. / Qualidade da silagem de cana-de-aÃÃcar elaborada com diferentes aditivos.
The objective of this research was to evaluate the effects of the use of additives on the quality and nutritional value of the sugarcane silage. Sugarcane variety RB-72454, at 18 months of regrowth, was stored for 180 days in experimental concrete silos (500 kg capacity). Treatments were expressed by additives amounts added to sugarcane silage at ensiling (b

16. PRODUCTION AND BROMATOLIGAL COMPOSITION IN HIDROPONIC WHEAT FORAGE / PRODUÇÃO E COMPOSIÇÃO BROMATOLOGICA DA FORRAGEM HIDROPÔNICA DE TRIGO
Hydroponics forage is an alternative to producers who need quality food to their animals, at times of the year with low demand. It was carried out two experiments inside a polyethylene greenhouse (tunnel), in the Ecophysiology and Hydroponic Research Center (NUPECH), of the Federal University of Santa Maria, Brazil. The objective this work was to evaluate th

17. Dinâmica de degradação in vitro da fibra em detergente neutro de forragens tropicais em função de suplementação protéica e/ou energética / In vitro degradation dynamics of tropical forages neutral detergent fiber according to protein and/or energy supplementation
The current thesis was based on two in vitro trials aiming at assessing the effect of protein and/or energy supplementation on ruminal degradation of fibrous carbohydrates of tropical forages. At Experiment 1, it was evaluated the effect of protein and/or energy supplementation on the utilization of fibrous carbohydrates from low quality forage by ruminal mi

18. Coffee hull or soybean hull replacing corn in diets based on sugar-cane for dairy cows / Casca de café ou casca de soja em substituição ao milho em dietas à base de cana-de-açúcar para vacas leiteiras
The objective of his work was to evaluate the effect of corn grain replacement by coffee hull or soybean hull in sugar-cane based diets, with 60% concentrate, for dairy cows, on intake and apparent nutrient digestibility, milk production and composition, animal body weight variation, body reserve mobilization, ingestive behavior and milk activity economic pe

19. Influence of different levels of dietetic NDF on the intake and apparent digestibility and on the feeding behavior of Santa InÃs ewes / InfluÃncia de diferentes nÃveis de FDN dietÃtico no consumo, digestibilidade aparente e comportamento ingestivo de ovelhas Santa InÃs
This work was carried out at the Setor of Ovinocultura of the Departamento de Zootecnia â UFLA to evaluate the effect of different levels of total and forage NDF (fNDF) in the diet offered to ovine on the intake and apparent digestibility of the diet and on the feeding behavior. A feeding behavior study and an in vivo digestibility assay were done to determ

20. "Efeito do teor de tanino do sorgo sobre a fermentação ruminal e parâmetros nutricionais de ovinos" / Effect of sorghum tannins on ruminal fermentation and sheep nutritional parameters
Sorghum bicolor (L.) Moench is an important cereal crop used in animal nutrition. However, this plant produces secondary compounds, such as condensed tannin, which are able to interfere in the animal digestion. Condensed tannins are macromolecules that can bind to other molecules such as protein and carbohydrates reducing the fully utilization of nutrients b

21. Silage of sugar cane with different additives at two cutting ages / Silagem de cana-de-aÃÃcar em duas idades de corte com diferentes aditivos
The bromatological characteristics and in situ degradability of sugar cane (Sacharum spp.) with different additives at two cutting ages before and after ensiling process were evaluated. The treatments were arranged in a completely randomized design with three replicates. The additives utilized were 1% of urea, 8% of ground ears with husks, 0.5% of mineral an

22. Exigências de proteína e energia líquidas para o ganho de peso de tourinhos das raças Nelore e Brangus alimentados com dietas com diferentes proporções de concentrado. / Protein and energy requirements for weight gain of Nellore and Brangus bulls fed with different concentrate levels.
The determination of energy and protein requirements for maintenance and growth of beef cattle is very important for an efficient animal production. Nellore and crossed breeds like Brangus are very used in Brazil, but the main source of information about nutritional requirements is the NRC, whose data was obtained with different breeds and environments. The
