生长肥育猪、产蛋鸡饲料复合添加剂饲养试验报告

<正> 为完善日粮的全价性及求得营养平衡,提高生长肥育猪、产蛋鸡的生产性能、饲料报酬和降低生产成本,我们应用动物营养学的最新成果,以我省(嘉山县)矿物质饲料资源——凹凸棒石为载体,研制成生长肥育猪、产蛋鸡饲料复合添加剂。为验证该添加剂的效果,曾在本所畜牧场进行饲养试验。现将试验方法和结果报告如下: 一、添加剂成分及配方 (一) 成分 1、常量元素。钙、磷、钾、钠、镁等。 2、微量元素。铜、铁、锌、锰、钴、钼、硒、氟、铬等。 3、维生素。A、D_2、D_3、E、K、B_1、B_2、B_3、B_6、B_(12)、C、烟酸、泛酸、胆碱等。

REPORT ON FEEDING TEST OF FINISHER PIG AND LAYER HEN WITH COMPLEX PREMIX

Complex premix had been applied to feed finisher pig and layer hen. Which were composed of trace minerals, vitamins and amino acids with the carrier of local feed resource——Attapulgite. In finisher pig experiment, total of 20 pigs(Soviet Large White×Ding Yuan, Large Yorkshire×DingYuan) were used in the study. The premix adding to the basal diet at level of 1％ was compared with the non—additive control diet, by 88 days. Then, the results showed that the premix group had faster 12％(P<0.01) daily gain and more 11.2％ efficiency of feed utilization than control group. In layer hen experiment, total of 58 hens(Ros)were used in the study. The premix adding to the basal diet at level of 1％ was compared with the non—additive control diet, by 78 days. The premix group had well—egg—laying performance and high feed conversion ratio than control group
