It was evaluated in this work the sensorial characteristics of the meat of non-castrate or castrated males feedlot finished and slaughtered at 16 (young steers) or 26 (steers) months old. The diet with 50 roughage: 50concentrate contained 11.8% of crude protein and 2.83 Mcal of digestible energy/kg of dry matter. The highest amplitude of the final pH of the meat was noted on the steers, and the lowest on the young steers. The meat of the non-castrate males, regardless to […]

The aim of this work was to verify if the presence of trees and its height in formed silvipastoral systems with eucalyptus planted in rank can modify the microclimate and improve the environment for bovine raising during the day in summer. It was evaluated the microclimate of the environment in formed silvipastoral systems in rank of eucalyptus with 8 m, 18 m and 28 meters of height, compared to a system no shade in the summer. The experimental design was […]

The carcass and meat characteristics were assessed of Devon steers finished in feedlot (CONF), temperate pasture ( ryegrass pasture – Lolium multiflorum Lam -PTEM), or tropical pasture (association of millet pasture – Pennisetum americanum (L.) Leeke and Alexander grass – Brachiaria plantaginea –PTRO). At the beginning of finishing the average weight of the steers was 320 kg and the age was 15 months. The animals in feedlot were fed feeds with 60:40 roughage:concentrate and slaughtered with similar weights of 388.3; […]

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, […]

This work was aimed to identify the typology and the characteristics of the goat milk production systems. Seventy rural properties were researched. Multivariate data analysis with cluster formation techinique was used, and also the identification of five different groups of production systems. The production systems were classified through technical and economical efficiency, ranking groups 1 and 2 as high technological level, groups 3 and 4 as medium level, and the group 5 as low level. The high technological level systems […]
