25. Effect of inoculants combining Lactobacillus buchneri strain LN40177 in different strata of the silo
ABSTRACT. The objective of this work was to evaluate the chemical composition and rumen disappearance rate of dry matter of corn silages with inoculants combining L. buchneri strain LN40177 in different strata of the silo. The experimental design was a 3x2 randomized complete block design, with three treatments: Control: corn silage without inoculant; 11CFT:

26. USE OF VIRGINIAMYCIN AND SALINOMYCIN IN THE DIET OF BEEF CATTLE REARED UNDER GRAZING DURING THE RAINY SEASON: PERFORMANCE AND RUMINAL METABOLISM
Resumo O rúmen é o órgão mais estudado no que se refere à interação simbiótica entre hospedeiro e a microbiota do trato digestivo dos ruminantes. Assim, objetivou-se avaliar os efeitos da inclusão de virginiamicina e de salinomicina ao suplemento para bovinos de corte com dieta de gramínea tropical no período das águas. Foram constituídos três

27. Roughage-free finishing diet based on whole corn grain and a mixture of additives for Nellore heifers
ABSTRACT This study was carried out to evaluate the effect of a blend of additives (choline, methionine, selenium, and organic zinc) on performance, feed efficiency, rumen parameters, and carcass traits of Nellore heifers finished with roughage-free diet. Nellore heifers (n = 36; average BW = 244±24.1 kg; average 24 months of age) were maintained in a feedl

28. Evaluating rumen fermentation kinetics and nutritive value of sunflower seed meal supplemented with acetonic extract of pomegranate peel using in vitro gas production technique
ABSTRACT. This study was conducted to investigate effects of supplementing different levels (0.0, 0.5 and 1.0% of buffered rumen fluid) of acetonic extract of pomegranate peel on rumen fermentation kinetics of sunflower seed meal (SFM), using in vitro gas production technique. The samples were incubated in syringes containing rumen liquor obtained from three

29. Aspectos morfológicos do rúmen, omaso e fígado de tourinhos alimentados com diferentes níveis de glicerina bruta
ABSTRACT The morphology of the ruminal and omasal mucosa and hepatic parenchyma of 44 young bulls submitted to four types of concentrates were evaluated by varying the inclusion level of crude Glycerin - CG (0, 6, 12 and 18%). The variables evaluated were number of ruminal papillae per cm² of wall; area of the papillae and total absorption surface per cm²

31. Characterization of ruminal acidosis and initial phase of laminitis inducted by oligofructose in crossbred calves
RESUMO: Uma das formas de se estudar a laminite bovina é sua indução experimental por meio do fornecimento de grande quantidade de carboidrato de alta fermentação. O protocolo mais eficaz até o momento foi o uso de oligofrutose. Objetivou-se avaliar aspectos clínicos e histológicos dos dígitos de bovinos na indução experimental de acidose ruminal

32. Body weight components of Nellore steers finished in tropical pastures
ABSTRACT. The aim of this study was to evaluate the effect of increasing levels of supplementation on body weight components of Nellore cattle grazing in Urochloa brizantha. Twenty-four steers with initial body weight (BW) of 371 ± 14 kg and average age of 26 months were used. Four animals were slaughtered at the beginning of the experiment as a reference a

33. Crude glycerin combined with food additives in feeding beef cattle
ABSTRACT The objective of this study was to evaluate the effects of adding crude glycerin with food additives (sodium monensin or essential oils) to the diets of beef cattle on feed intake, ruminal parameters, in vitro digestibility, and production of greenhouse gases. Five ruminally cannulated Nellore steers were randomly assigned in a 5×5 Latin square des

34. In vitro study of postbiotics from Lactobacillus plantarum RG14 on rumen fermentation and microbial population
ABSTRACT An in vitro study was carried out to identify the effects of different inclusion levels of postbiotics from Lactobacillus plantarum RG14 on rumen fermentation profiles, gas production kinetics, and microbial population in rumen fluid collected from goats. Postbiotics were added at different levels (0, 0.3, 0.6, 0.9, and 1.2%) and incubated for 72 h

35. Avaliação in vitro das folhas de palmeiras como alimento de digestibilidade de ruminais e produção de gás
RESUMO. Este estudo teve como objetivo avaliar as folhas de palmeiras sozinhas ou suplementadas com enzimas fibrolíticas, como uma alternativa de degradação da fibra na digestibilidade de nutrientes de ruminantes e produção de gás. Os tratamentos foram: Feno (Trifolium alexandrinum), folhas de palmeiras, e folhas de palmeiras com adição de enzimas fi

36. Intake, apparent digestibility, rumen fermentation and nitrogen efficiency in sheep fed a tropical legume silage with or without concentrate
Abstract Legume silage can increase the forage quality of the diets as well as supply it with nitrogen, calcium and phosphorus. The objective was to evaluate the intake, apparent digestibility, rumen fermentation and nitrogen efficiency in sheep fed a tropical legume silage with or without concentrate. Twelve crossbred sheep with an average initial body weig
