Valor nutritivo, energia líquida de dietas e morfometria intestinal de suínos alimentados com níveis crescentes de casca de soja

Pork is the most produced and consumed in the world and considered one of the main activities of Brazilian agribusiness. Currently, Brazil is the fourth largest producer of pork in the world according to USDA, (2015). But during the year periods of instability linked to the acquisition of raw material for a good development of the activity has been happening due to the rise or fall of prices of the kilo of the finished pig and also the variation and even lack of the inputs used in the diets of these animals , USDA (2015). The pig is an animal that presents easy acceptance to different foods, so as an alternative there are these market instability, alternative products can be used in diets aimed at reducing competition from the use of corn and soybean, oscillation in prices and availability Optimizing production. The use of foods with a fiber content not commonly used before has been growing over the years, and as these animals have been developing and adapting these foods has gained more space like the soybean that was little used for this animal species .Soybean peel as an alternative food in the diet of pigs has been shown to be efficient in increasing consumption levels when used in percentages of 12 to 24% in the total diet, with little or no effect on daily weight gain, digestibility of Nutrients and final performance of animals BOWERS et al. (2000). The percentage of fiber contained in the soybean hull, up to the 30% level of substitution in the basal diet, does not negatively influence the nutrient uptake for pigs in the growth phase, and does not affect the final weight gain and digestibility. Thus, the objective of this study was to evaluate the best level of substitution of the alternative soybean meal in diets of growing pigs with no change in the weight gain of the animals and in the final quality of the product produced.
