Pigmentantes naturais em dietas de codornas japonesas a base de arroz integral descascado e não polido

Abstract

espanolDesenvolveu-se um experimento a fim de verificar o efeito da inclusao de pigmentos naturais, feno de alfafa (FA), colorifico de urucum (U) e beterraba (B), em uma dieta a base de arroz integral descascado e nao-polido e farelo de soja sobre a coloracao das gemas dos ovos de codornas. Foram utilizadas 100 codornas japonesas com 70 dias de idade. Os tratamentos foram T1: dieta controle (arroz integral descascado e nao-polido em substituicao total ao milho); T2: T1 + de 4% FA; T3: T1 + de 8% FA; T4: T1 + de 12% FA; T5: T1 + 4% de U; T6: T1 + 8% de U; T7: T1 +12% de U; T8: T1 + 4% de B; T9: T1 + 8% de B; e T10: T1 + 12% de B. Ao final de 15 dias foram verificadas as coloracoes das gemas dos ovos com colorimetro. O feno de alfafa promoveu diminuicao da luminosidade e a cor variou do verde ao amarelado. Houve tambem aumento da saturacao da cor com o aumento dos niveis de feno de alfafa na dieta (P EnglishA trial was conducted to evaluate the inclusion of natural pigments, alfalfa meal (FA), annatto (U) and sugar beet (B) in a diet based on peeled and unpolished whole rice and soybean meal. A total of 100 70-day-old Japanese quails were used. Treatments were T1: control diet (peeled and unpolished whole rice in full replacement of corn); T2: T1 + 4% FA; T3: T1 + 8% FA; T4: T1 + 12% FA; T5: T1 + 4% U; T6: T1 + 8% U; T7: T1 + 12% U; T8: T1 + 4% B; T9: T1 + 8% B; and T10: T1 + 12% B. After 15 days of trial yolk colour was measured with a colorimeter. Alfalfa meal decreased brightness and the colour ranged from green to yellowish. Additionally, colour saturation was augmented with increased levels of alfalfa meal in the diets (P
