【摘要】 在36头杜长大杂交生长肥有猪(17kg～53kg)试验60天发现,用蛋白质螯合态有机铁(250克/吨)取代阿散酸(10克/吨),同样可以使猪只皮红毛亮,并且红得自然、均衡。从促生长效果看,二者促生长效果差异不显著,但螫合态有机铁组的饲料转化效率比阿散酸组高4.7%。所以虽然蛋白质螯合态有机铁目前价位偏高,且添加量较大,但实际每公斤增重成本蛋白质螯合态有机铁组要低于阿散酸组。因此蛋白质螯合态有机铁是一种更具竞争优势的新型大然饲料添加剂。更多还原

【Abstract】 Thirty six Durac × Large White × Landrace hybrid (17-53 kg) were used to evaluate the effect of Proteinated Iron (15% Iron, Bioplex IronR) at 250 g/t on substitution of Arsenic acid (100 g/t) in a 60 day feeding trial. Observation indicated that both Proteinated Iron and Arsenic acid were able to make pig pinky, however, Proteinated Iron produced a uniform and natural pink color. Growth rate of both Proteinated Iron and Arsenic acid were not significantly different (p>0.05), but FCR of pigs fed Proteinated Iron was improved by 4.7% compared with those pig fed Arsenic acid. Unit price and usage rate of Proteinated Iron were relatively higher than those of Arsenic acid, however, actual cost per unit gain was lower in Proteinated Iron fed pigs than those fed Arsenic acid. In conclusion, Proteinated Iron is a better feed additive with competence in pig production.更多还原
