The results showed that adding feed-grade proteinase in diets enhanced anti-diarrhea capacity of piglets and improved signifi- cantly production performance and breeding efficiency of piglets. This study provided the reference for rational utilization of feed-grade proteinase in actual production.展开更多

This fish is not used in Mexico for human consumption and has been regarded by fishermen as a pest; not having a use for this species has represented an ecological problem disposed on the banks of water bodies. This work allows to observe as a considered plague resource can be used in animal feed through its transformation in silage acid, thus contributing to the establishment of a new activity of the fishermen and providing the necessary protein for the production of pigs, sheep and cattle in the region, constituting both a complementary relationship： Fishermen obtain income by selling the silage to livestock producers and they get a good quality product that allows them to reduce the costs of food.展开更多
