CARACTERIZAÇÃO NUTRICIONAL E USO DE DDGS EM DIETAS PARA SUÍNOS EM CRESCIMENTO E TERMINAÇÃO - ABORDAGEM ANALÍTICA
DOI:
10.31413/nativa.v4i2.2988Resumo
Alimentos alternativos como os grãos secos destilados com solúveis (dried distillers grains with solubles - DDGS) estão sendo constantemente estudados, com o objetivo de substituir milho e farelo de soja, devido à similaridade na quantidade de nutrientes e com menor custo. Foram revisados artigos entre os anos de 2002 e2015 publicados em periódicos internacionais contidos na plataforma Science Direct e Animal Science Publications, nos quais as dietas para suínos em fase de terminação apresentaram níveis de inclusão de DDGS de milho de 0, 5, 10, 15, 20, 25 e 30%. Com uma base de dados elaborada em planilha do Excel foi realizada uma análise descritiva utilizando os níveis de significância obtidos a partir dos resultados dos trabalhos referenciados. Os expressivos valores de energia, proteína bruta e fósforo digestível, o faz muito atraente para substituição parcial da alimentação animal. Observa-se que conforme aumenta a concentração de DDGS de milho na dieta, o consumo de ração e consequentemente o ganho de peso diminuem. Em conclusão, o DDGS pode ser incluído em rações para suínos nas fases de crescimento e terminação com até 20% de inclusão sem afetar negativamente o desempenho.

NUTRITIONAL CHARACTERIZATION AND USE OF DDGS IN GROWING AND FINISHING PIG DIETS - ANALYTICAL APPROACH
ABSTRACT
Alternative ingredients such as dried distiller’s grains with soluble (DDGS) are constantly being studied in order to replace corn and soybean meal, due to similarity in the amount of nutrients and less costly. Articles between the years 2002 and 2015 published in international journals were reviewed contained on the Science Direct and Animal Science Publications platforms, in which the diets for finishing pigs showed the levels of inclusion 0, 5, 10, 15, 20, 25 and 30% of corn’s DDGS. With a database compiled in Excel spreadsheet a descriptive analysis was performed using the significance levels obtained from the results of the referenced works. The expressive amounts of energy, crude protein and digestible phosphorus, makes it very attractive for partial replacement of animal nutrition. Was observed that with increasing concentration of corn’s DDGS in the diet feed intake and consequently weight gain decreases. In conclusion, DDGS can be included in diets for pigs in the growing and finishing phases up to 20% of inclusion without negatively affecting performance.
