Níveis de proteína em rações com milho ou sorgo para codornas japonesas

Abstract: Palavras chave adicionaisAlimento alternativo. Desempenho. Qualidade de ovos.resUMo Objetivou-secom esta pesquisa avaliar níveis de proteína bruta em rações com milho ou sorgo sobre o desempenho e qualidade de ovos de codornas japonesas na fase de postura. Foram utilizadas 320 codornas com idade inicial de 14 semanas. O delineamento experimental utilizado foi o inteiramente casualizado em esquema fatorial 2 x 5, sendo 2 alimentos (milho e sorgo) e 5 níveis de proteína bruta (16, 18, 20, 22 e 24%), totalizando … Show more

“…Sorghum in diets for laying hens may have advantages, as it is marketed at a price around 80% of the price of corn, despite the nutritional differences between both (Fassani et al, 2019). Corn has lower protein content, more oil and energy, and more lysine and methionine than sorghum, having similar tryptophan quantity between both, the digestibility of some essential amino acids of corn and sorghum is, respectively, 93% and 83% for methionine, 90% and 78% for lysine, 87% and 78% for threonine and 78.2% and 74.5% for tryptophan, which demonstrates lower availability of sorghum amino acids about corn (Maciel et al, 2019).…”

“…Another indication that protein supplementation was adequate in the studied diets is the lack of effects on the Haugh unit and albumen weight since, in a previous study, Maciel et al (2019) demonstrated that diets with crude protein reduction supplemented with essential and nonessential amino acids meeting the requirements of laying Japanese quails, would have the characteristics of albumen equivalent to conventional diets of high crude protein.…”

“…Mesmo possuindo maior teor proteína que o milho, a principal preocupação em relação a utilização do sorgo na alimentação de codornas é o seu teor de taninos, mesmo este sendo reduzido com o uso de novas variedades de sorgo (MACIEL et al, 2019).…”
