ABSTRACT The objective of this study was to evaluate, through principal component analysis, the effect of different feedlot structures on climatic conditions, nutrient intake, and performance of Nellore bulls during the feeding period in the semi-arid region. Data from 225 non-castrated Nellore bulls with initial mean body weight (BW) of 294 ± 19 kg and age of 24 months were used. This was done in a completely randomized design with three feedlot structures (no shading, natural shade, and artificial shade […]

This work aimed to assess the effects of preslaughter lairage time on the welfare and mortality of broilers transported in different farm-abattoir distances. It was evaluated 215 poultry transport trucks from a commercial poultry slaughterhouse from 2006 to 2007. Data were obtained from the holding area acclimatized through fans and water misting in the mornings, afternoons and at night. The thermal variables (temperature and relative humidity), distance, lairage time and density of birds per cage were considered in the analysis. […]

It was aimed to verify the effect of the presence of trees and their heights in silvipastoral system on the intake behavior of Nellore heifers in the summer. Ten heifers for the following systems were used: system without shade, silvipastoral system with 8-meter and 18-meter trees. The data were collected in three days during 12 hours, subdivided in morning (7:15 a.m. to 1. p.m.) and afternoon (1:15 p.m. to 7 p.m.). It was evaluated the times and frequency of grazing, […]
