Replacing regular urea (RU) by slow-release (SRU) at two levels of non-protein nitrogen (NPN) in concentrate, offered with low-quality roughage, was evaluated beef steers on dry matter intake (DMI), ruminal fermentation parameters, plasma (PUN), total tract apparent digestibility diets and situ degradability sources. Eight ruminally cannulated were allocated into 4x4 Latin squares, totalizing four treatments: 40 NPN/0 SRU: 40% concentrate crude protein (CP) as NPN, resulting from 0% SRU 100%...
Cows fed high-protein diets may have impaired reproductive performance. Although the pathogenesis has not been completely elucidated, it appears that only uterus, but also follicle and oocyte, are affected by excessive plasma urea nitrogen (PUN) concentrations. Thus, objective was to determine effects of short-term feeding on competence bovine oocytes. Forty crossbred heifers (Bos indicus vs Bos taurus) were allocated two groups, namely CONTROL (maintenance diet) UREA diet supplemented with...
O objetivo deste trabalho foi avaliar o efeito de formas processamento milho na degradabilidade da matéria seca, amido e proteína em rúmen bovinos. Foram utilizadas 12 fêmeas bovinas mestiças, não gestantes lactantes, portadoras cânulas ruminais com peso médio 647 kg. Foi utilizado um delineamento inteiramente casualizado três tratamentos: quebra (1,6 mm), moagem fina (0,8 mm) floculação (8,25 mm; 270 g/L) dos grãos milho, 4 repetições por tratamento. Os sacos náilon contendo nos diferentes...
The ability of cattle to select the roughage and concentrate in their diets under different environmental temperatures was studied 12 cannulated cows, during 30 days. experimental design completely randomized with two treatments: thermal comfort (21oC) stress (climatic chamber, 38oC). Cows were fed a diet sugar cane plus urea mixture, which offered separately ad libitum. cows identified by comparing composition selected environments, as weel ruminal parameters digestibility. A significant...
Nine ruminally cannulated cows fed different energy sources were used to evaluate an avianderived polyclonal antibody preparation against specific ruminal bacteria and monensin on microbial community diversity. The experimental design was three Latin squares 3 x distinguished by the main source in diet [dry-ground corn grain, high moisture silage or citrus pulp]. Inside each square, animals received one of feed additives per period [control, preparation]. Each lasted 21 days where 20 for...
ABSTRACT The effect of a polyclonal antibody preparation (PAP) against Streptococcus bovis and Fusobacterium necrophorum on ruminal fermentation digestion in ruminally cannulated cows was investigated two 3 × Latin squares factorial arrangement treatments 2 regarding feed additives (PAP powder (PAPP) liquid (PAPL) presentation) plus control (CON) managements diets (with or without adaptation to highly fermentable carbohydrate diets). Adapted group had greater DMI (p < 0.0001) DM 0.0001), NDF...
Objective: Feed additives that modify rumen fermentation can be used to prevent metabolic disturbances such as acidosis and optimize beef cattle production. The study evaluated the effects of liquid powdered forms polyclonal antibody preparation (PAP) against <i>Streptococcus bovis</i> Fusobacterium necrophorum on parameters in ruminally cannulated non-lactating dairy cows were adapted or unadapted a high concentrate diet.Methods: A double 3×3 Latin square design was with three...
Abstract Introduction HIV rebounds after cessation of antiretroviral therapy, representing a barrier to cure. To better understand the virus reservoir, analysis pipelines have been developed that categorize proviral sequences as intact or defective, and further determine precise nature sequence defects may be present. We investigated effects different had on characterization HIV‐1 sequences. Methods used single genome amplification generate near full‐length (NFL) DNA sequences, defined...
