摘要
选用45头试验牛按体重大小,平均分成对照组、营养调控组和中草药组3个组。后两个组作为试验组,分别饲喂课题研制的营养调控剂和中草药添加剂预混料。结果表明:营养调控组的牛平均日增重1.308kg,比对照组的增重提高34.4%,增重差异显著(P<0.05),中草药组的牛在试验后期表现出强劲的生长优势。每增重1kg活重,营养调控组比对照组少消耗饲料干物质2.25kg和少消耗精饲料1.39kg,饲料报酬提高36.4%,差异显著(P<0.05)。
Select 45 experimental beef cattle and divide into contrast group, adjusted and controlled Nutrition group and herbal group on average, according to weight size. The last two groups as experimental group, feeded adjusted and controlled Nutrition pharmaceutical and herbal additive compounding separately about seminar researched and manufactured. The experiment results indicated that the adjusted and controlled Nutrition group increases weight 1. 308 kilograms the per - day increase weigh, improves by 34.4 % than contrast group, the difference is significantly (P 〈 0.05), the same time, the experiment results demonstrated the powerful growth advantage at later stage of experiment about herbal group. Per- 1kg lives heavily to in- crease weight each time, the adjusted and controlled Nutrition group consumes the dry feed 2.25kg less than contrast group and consumes concentrated feed 1.39kgs less than the cofitrast group, the remuneration of feed is raised by 36.4 %, the difference is significantly (P 〈 0.05).
