Abstract
The knowledge of the chemical-bromatological composition of the pig diets provides decision-making for the obtaining of the maximum production performance of the animals. Therefore, the nutritional quality of commercial swine diets in each production stage was evaluated. Six different commercial diets used in IF Southeast MG, Rio Pomba Campus (Federal Institute Southeast MG, Rio Pomba) were collected, the analyses of moisture, mineral matter, crude protein, total phosphorus and water activity being conducted. The chemical-bromatological composition found was compared with the information reported on the label as well as the nutrient requirements for each phase of the pigs. Some irregularities were observed when comparing the actual composition with that reported on the label. The pre-starter diet presented a moisture value above what is described on the product label. Regarding crude protein, the starter and grower diets did not meet the minimum levels specified on the label. As for phosphorus, the pre-starter and starter diets did not meet the levels shown on the labels. Regarding the crude protein requirements, the pre-starter diet presented value below and pregnancy and finisher diets showed values far above that required by pigs in these phases. For the water activity, no diet posed risk to fungal growth.
Highlights
The knowledge of the chemical composition of pig diets can provide the grower decision-making for the obtaining of the maximum production performance of animals, mainly to find fraud and lack of adjustments of the nutritional levels established on the levels of the packages to meet the nutritional levels established adjustments on the labels of commercial feeds
The labels of the containers presented the data of basic nutritional composition including moisture, crude protein, ether extract, fibrous matter, mineral matter, calcium and phosphorus, as required by Brazilian legislation (Brasil, 2009)
In relation to the levels of crude protein (CP), both the diets SD and GD did not meet the minimum levels specified on the package, values a little below the values described on the labels being found
Summary
The knowledge of the chemical composition of pig diets can provide the grower decision-making for the obtaining of the maximum production performance of animals, mainly to find fraud and lack of adjustments of the nutritional levels established on the levels of the packages to meet the nutritional levels established adjustments on the labels of commercial feeds.The quality has been the objective in all the branches of the industry. The knowledge of the chemical composition of pig diets can provide the grower decision-making for the obtaining of the maximum production performance of animals, mainly to find fraud and lack of adjustments of the nutritional levels established on the levels of the packages to meet the nutritional levels established adjustments on the labels of commercial feeds. The quality of a product, defined as its suitability for the use to which it is intended, can be warranted by lots of measures, which abridge in the application of safe technologies to raw materials of good quality. The quality of the raw materials and feeds intended for animal feeding has reached quality levels comparable to the standards of products intended for human consumption. Due to the intensification of farming activity, the feeds given to the livestock food should be nutritionally balanced as well as the health guarantees for their supply and marketing (Gabbi et al, 2011)
