笼养原鸡3种饲料的择优试验

Digestion of Three Diets by Red Jungle Fowl in Cage

笼养条件下 ,分别用 16 1#、72 2 #全价配合颗粒饲料和某鹌鹑饲养场的自配粉状料对 4只成年笼养原鸡 (Gallusgallus)进行消化试验。结果表明 ,成年原鸡对 3种饲料干物质、粗蛋白及碳水化合物的表观消化率 ,自配料均低于 16 1#、72 2 #饲料 ,且与 16 1#、72 2 #饲料差异显著 (P <0 0 5 ) ,而 16 1#与 72 2 #之间无显著差异 (P >0 0 5 ) ;3种饲料间粗脂肪的表观消化率均无显著差异 (P >0 0 5 )。并结合饲料的适口性、料增重比等方面评价的结果得知 ,以颗粒状的 72 2 #家鸡饲料作为原鸡的基础日粮就于其它种类饲料 ,蛋白质含量高的饲料 ,原鸡对其的消化率也高 ,日粮中蛋白质的含量以 19%为最佳。

Four adult red jungle fowls kept in cage were used to determine the digestibility of 3 diets (two commercial chicken pellet feed 161# and 722# and 1 powder compound feed prepared by a quail farm). The apparent digestibility of DM, CP and carbohydrates of 161# and 722# were similar but differed significantly from powder feed ( P< 0.05). The digestibility of fat of 3 diets did not differ ( P> 0.05 ). Combined with the observations of palatability and the ratio of feed consumption and weight gain, 722# pellet feed was a ideal basal feed for adult red jungle fowl. The digestibility of diet increased as the increase of dietary protein content with 19% of dietary protein being the best.
