Subprodutos da soja na alimentação de aves: Revisão

Abstract

The use of soy by-products in poultry feed has proven to be an important sustainable alternative, being capable of minimizing the environmental damage caused by the disposal of these residues and at the same time reducing the cost of production. However, for the use of these by-products in poultry feeding, it is necessary to know their chemical composition, antinutritional factors and also necessary measures to reduce these factors, as well as the best levels of inclusion that must meet the nutritional requirements of the animals in each production phase. In this context, the purpose of this review is to demonstrate the potential use of soy by-products (soy husk, soy acid oil, glycerin, soybean chopsticks, soy gum and okara) in the feeding of broilers, laying hens and cutting and laying quails, as well as the adverse effects that each can cause on animal performance. To carry out this review, analysis was carried out in several scientific studies that used soy by-products in the feeding of broilers and laying hens. It can be concluded that the potential for using soy by-products in Brazil is enormous, which expands the alternative ingredients that can replace soybean meals in poultry feed, without causing damage to performance, intestinal health, biochemical and hematological parameters, in addition to reduce the environmental pollution generated by the inappropriate disposal of these residues, as these ingredients could be a way to reduce the costs of diets.

Effects of the Addition of Trichoderma reesei Cellulase to Broiler Chicken Diets for a 21-Day Period

“…Nitrogen is one of the main pollutants in pig manure, which can be applied to poultry manure. The results of previous studies have demonstrated that in the pre-initial period from four to seven days, the addition of both powdered and liquid cellulase enzyme significantly reduced nitrogen excretion, improving nutrient utilization [28,29]. A similar result was found in reference [30].…”

Produtividade de Cártamo submetido à deficiência hídrica

“…A soja (Glycine max) é uma das principais leguminosas produzidas no mundo, devido ao elevado potencial de produção e valor nutritivo, podendo ser utilizada na nutrição humana e animal, possuindo papel de destaque na economia brasileira (Gouveia et al, 2020). A produção mundial foi 348,7 milhões de toneladas, sendo que o Brasil produziu 117,8 milhões de toneladas, se tornando o segundo maior produtor mundial (Fao, 2020).…”

Análise de grafos de visibilidade do mercado brasileiro de soja, milho e carne de frango

“…O aumento do consumo dessa commodity causa alterações em seus preços, trazendo impacto ao orçamento dos brasileiros. O milho como fonte de energia e a soja como fonte de proteína (Gouveia, de Paulo, da Silva, de Sousa, dos Santos, & Minafra, 2020) são os principais insumos utilizados na formulação das rações de frangos de corte (Oliveira Júnior, Wander, & Figueiredo, 2014).…”
