Long-term impact of a 4-day feed restriction at the protozoea stage on metaboli...

Based on the ‘‘nutritional programming’’ concept, we evaluated the long-term effects of an early four-day caloric restriction (40% reduction in feed allowance compared to a normal feeding level) at the protozoea stage in whiteleg shrimp. We analyzed long term programming of shrimp by studying metabolism at the molecular level, through RT-qPCR of key biomarkers (involved in intermediary metabolism and digestion)...

Efeitos do incremento de fibra dietética sobre digestibilidade, desempenho e ca...

Effects of increasing dietary fiber on digestibility, performance and carcass c...

Female pigs that are intended to be used as sows have to follow a dietary plan that restricts caloric intake. Roughages due to their high content of fiber are low energy sources for swine. This feeding strategy gets around the excessive body fat accumulation. Aiming to study these aspects, prepuberty and puberty gilts were fed isoenergetic and isoproteic rations containing 0; 6.6; 13.2 and 19.8% of neutral dete...

Effects of increasing dietary fiber on digestibility, performance and carcass c...

This work aimed to evaluate the effects of fibrous ration on parameters of nutrient digestibility, animal performance and carcass characteristics, using 24 crossbred gilts during growing and finishing phases in a completely randomized design experiment. The animals were fed ad libitum with isonutrients rations containing increments of 0 or 8% neutral detergent fiber (NDF), obtained through the inclusion of 0 or...

Morphology of digestive and non-digestive organs of pigs from modern lineages d...

The genetic market makes use of various modern swine genotypes that present high capacity for muscular mass development. These genetic lines have been used in swine production without existing scientific information about morphology, knowledge that can elucidate factors related to growth performance, such as weight gain and food conversion in lean meat yield. The aim of this experiment was to compare the morpho...

Effects of increasing neutral detergent fiber in swine diets on the morphology ...

Objetivou-se avaliar os efeitos da inclusão na ração de 0 ou 8% de fibra em detergente neutro proveniente de feno de gramínea sobre a morfologia dos órgãos digestivos e não digestivos de suínos nas fases de creche e de crescimento-terminação. Foram utilizados suínos mestiços alimentados à vontade com rações isoprotéicas e isoenergéticas, em experimento inteiramente casualizado. Ao final de cada período, os anim...
