The aim of this paper is to assess economic and biologic feasibility of different feed categories in swine prefattening and fattening stages. Equally important is to quantify the contribution of nutrients, digestible energy, and crude proteins based on conventional raw materials (corn and soybean),...

The aim of this paper is to assess economic and biologic feasibility of different feed categories in swine prefattening and fattening stages. Equally important is to quantify the contribution of nutrients, digestible energy, and crude proteins based on conventional raw materials (corn and soybean), as well as nonconventional ones (parted rice, fat and sunflower meal). A composition analysis was made, and rations for pigs were simulated in the abovementioned stages. According to the standard supplies, the protein levels found in the commercial feed type were either excessive or deficient at times in relation to animal requirements. The costs of production were subsequently increased, and nutritional unbalances were observed, making feed rations costlier than the feeds made for the stages under the study, using nonconventional raw materials. |
