ABSTRACT We examined the effect of dried distillers grains with solubles (DDGS) in diets for late gestating sows on sow and litter performance, colostrum chemical composition, and sow behavior. Sixty gestating sows of 3.77±1.65 parity were divided into three groups of 20 animals, in a randomized block design with 0 (corn-soybean meal diet), 150, or 300 g kg−1 DDGS from 84 days of gestation until farrowing. Sows fed 300 g kg−1 DDGS presented a lower frequency of standing position and […]

A precisão de produção de gado (PPG) se constitui em ampliação do conceito de agricultura de precisão (AP) e que inclui todos os componentes de ecossistemas agrícolas, especialmente as interações animais e planta-animal. O solo, plantas e as interações solo-planta são temas da AP ou de locais específicos em cada fazenda, onde o principal objetivo é explorar a natural heterogeneidade espacial para aumentar a eficiência e reduzir impactos no meio ambiente. Para a maioria das situações a AP tem sido […]
