Soybean Hulls and White Oat Grains in Steer Finishing.

This study aimed to investigate the feasibility of using ground soybean hulls and white oat grains to finish steers reared exclusively on concentrated feed. We used 33 steers, predominantly of Charolais or Nellore breeds, and randomly assigned the animals to the treatments, blocking them according to genetic predominance. The diets were isonitrogenous, and the treatments consisted of soybean hulls, white oats, and mix these in equal parts, supplemented with calcitic limestone and a protein nucleus.

Qualitative characteristics of meat from cull cows of different genotypes and age class slaughter under different finishing systems: a meta-analytic approach.

The aim of this study was to evaluate, by meta-analysis, the quality of the meat of the cows according to genotype, termination system and age class slaughter. During an online research were identified 15 articles with information related to meat quality of slaughtered cows. The data were grouped according of the genotype of cows being: zebu or continental defined, crossed zebu x british or zebu x continental; according to termination system: feedlot or grassland; according to age of slaughter, where: up to 4 years old (young), 4-8 years old (adult) or more than 8 years old (old).

Use of the correlation between input variables in estimating the risk of feedlot finishing of steers and young steers.

The objective of this study was to evaluate the risk of feedlot finishing of steers (22.8 months) and young steers (15.2 months), using or not a correlation between the random input variables (data collected from 2004 to 2010) in the simulation of the Net Present Value (NPV) financial indicator.
