Effect of dietary supplementation of frutescens seeds (Perlila Frutescens L.) on growth performance,slaughter weight,carcass weight,and meat quality of male local duck

摘要

This experiment was aimed to observe the effects of Frutescens seeds (Perilla frutescens L.) levels in the diet on the growth performance,slaughter weight,carcass weight,and meat quality of male local duck.A total of 90 ducks were divided into 3 treatment groups with five replicates.The treatments were:basal diet without supplementation frutescens seeds meal (PO),experimental diets with 2.5% frutescens seeds meal (PI);and 5% frutescens seeds meal (P2).The experiment was conducted for 60 days.Average daily gain (ADG),slaughter weight,carcass weight,crude protein and fat contents of duck meat were observed.The data were analyzed with one way analysis of variance (ANOVA).if there was significant differences among treatments,Duncan's multiple range test (DMRT) were applied.The body weight,feed intake,slaughter weight,carcass weight,dry matter,and meat protein content were not affected by the dietary treatments.However,the effect of the Frutescens supplementation in the diets significantly affected ADG,non-carcass weight,and fat content in the duck meat.The highest fat content of meat has been found in the duck raised with 5% of Frutescens seeds supplementation in the diet.These results suggested that the use of 5% Frutescens seeds supplementation in the diet effectively increased ADG,non carcass weight,and fat content of meat.Whereas other traits observed in this study were not affected.
