猪微量元素营养配方试验研究

STUDIES OF TRACE MINERAL PRESCRIPTION FOR PIGS

研究了两种不同复合微量元素营养配方对断乳仔猪与生长肥育猪生长、增重和饲料效率的影响。植物性日粮中添加复合微量元素,仔猪增重提高10.72%。(P<0.05);而在植物性饲料加鱼粉日粮中添加,则仔猪增重提高18.26%(P<0.01)饲料消耗分别降低7.86%与10.24%。生长肥育猪日粮中添加复合微量元素,配方一使猪增重提高4.57%(P>0.05),配方二提高19.15%(P<0.01)。饲料效率分别为4.15与3.71。表明复合微量元素配方的拟定不能简单地以元素的化学位作为唯一依据,必须同时考虑微量元素的生物学效率。

An experiments were conducted to study the effect of trace mineral complex for growth of weaning pigs (Exp. Ⅰ)and gain of growing-finishing pigs (Exp. Ⅱ). According to make up a prescription the trace mineral complex was added to plant diet, daily gain of weaning pigs increased at 10, 72% (P<0.05) and to 5% fish meal+plant diet increased at 18.26%(p<0.01). Consume feeds correspondingly decreased at 7.86 and 10.24. According to make up two different prescription the effects was different. when Pre. 1 was used to growingfinishing, the daily gain increased at 4.57% (P>0.05). when Pre.2 was used to growing-finishing, the daily gain increased at 19.15% (P<0.01). The effieiencies of feed utilization correspondingly were 3.71 and 4.15. when work out prescription of trace mineral, both chemical value and biological efficiency ought to consider.
