The objective were to identify and quantify the rumen protozoa from two genetic groups of beef cattle (Nellore crossbred European cattle) subjected three feeding systems (pasture, pasture supplement, confined). Samples contents obtained center ruminal mass after slaughter. Quantification identification performed with a Sedgewick-Rafter counting chamber by optic microscopy. Data analyzed using general linear analysis methodology Poisson distribution (1 %). In addition, data underwent Analisys...
This study aims to evaluate different techniques for determination of soluble sugars (fraction CA) in foods used ruminant nutrition. Feed analyzed were: sugar-cane, bermuda grass, corn meal and soybean meal. Dry matter (DM), ash, ether extract (EE) crude protein (CP) were determined make possible the calculation total carbohydrates concentration samples. The carbohydrate fraction 15 repetitions each sample by two analytical techniques. One technique based on extraction its quantification...
The objective of this study was to determine the requirement digestible methionine + cystine brown-eggs laying hens from 50 66 weeks age at end first production cycle. design completely randomized, with 150 Brown Shaver hens, which were distributed in five treatments six replications birds each. Birds received a basal diet 2857 kcal/kg metabolizable energy and 15.97% crude protein, supplemented 0.132; 0.174, 0.215, 0.256 0.298% DL-methionine (98%), order provide 0.572, 0.613, 0.653, 0.693...
