Farelo de soja proveniente de grãos avariados na alimentação de suínos

Abstract

Soybean is the main source of protein of plant origin in animal feed, as it has high amounts of protein, amino acids and energy in its nutritional composition, so we must guarantee its quality. According to Normative Instruction 11/2007 of the Ministry of Agriculture, Livestock and Supply, responsible for the classification of soybeans, a maximum limit of 8% of damaged grains is allowed in the batches of soybeans that arrive at the crushers, this batch being classified as fra do type, with this, it must be re-beneficiated to frame in type. It is believed without scientific basis that damaged soy should not be fed to animals, as it can compromise their performance and health. Therefore, the objective of this thesis was to evaluate the different levels of replacement of standard soybean meal by soybean meal from damaged grains, in performance, intestinal morometry, blood parameters, physical and qualitative quality of swine care. Therefore, two experiments were carried out to evaluate different levels of replacement of the damaged soybean meal. The first experiment evaluated the levels 0, 4, 8, 12 and 16% of substitution, a difference was observed for performance, intestinal microvilli and blood biochemical parameters (urea and aspartate amintransferase-AST). We conclude, therefore, that the use of up to 16% does not compromise the performance and health of the growing and finishing pigs. damaged soybean, performance, intestinal microvilli, blood biochemical parameters, digestibility and pork quality were evaluated. Therefore, the different replacement levels studied did not influence the results of performance, intestinal microvilli, blood biochemical parameters, digestibility and meat quality. In this way, we concluded that the replacement of 100% of the soybean meal from damaged grains did not compromise the performance and health of the pigs.
