Abstract

ESTEVEZ ALFAYATE, Jorge A. Nutritional Management in the Prefattening and Fattening Stages on an Integrated Swine Farm. Rev. prod. anim. [online]. 2016, vol.28, n.2-3, pp. 12-19. ISSN 2224-7920.

The aim of this paper is to assess economic and biologic feasibility of different feed categories in swine prefattening and fattening. Equally important is to quantify the contribution of nutrients, digestible energy, and raw proteins based on conventional raw materials (corn and soybean), as well as non-conventional ones (parted rice, fat and sun flower meal). A composition analysis was made, and rations for pigs were simulated in the above-mentioned stages. According to the standard supplies, the protein levels found in the single-type feed were either excessive or deficient at times, in relation to the 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 non-conventional raw materials.

Keywords : nutrition; pigs; raw materials; simulation; economic feasibility.
