Abstract

In this study, we aimed to evaluate the effect of supplementation of mineral nano particles on piglet growth by assessing the live weight gain, the total feed intake, and the feed conversion ratio. A total of 240 Duroc-LandraceYorkshire piglets weaned at 25 days were randomly assigned to 4 treated groups and 1 control group. Piglets of Group I was fed with basal diets supplemented with 1.6 mg/kg nMn, 20 mg/kg nFe, 2 mg/kg nCu, 0.1 mg/kg Co, 0.1 mg/kg nSe, and 20 mg/kg nZn. The nano mineral content of Group II, III, and IV were 2, 4, and 8-fold higher than Group I, respectively. The results showed that the higher concentration of mineral nano particles supplementation (group III and IV) associated with the higher live weight gain. The piglet from group IV showed a highest live weight gain (36.68 ± 0.34 kg) comparing to other groups (P < 0.01). All groups of treatment with mineral nano particles supplementation showed the lower feed conversion ratio comparing to control group. There was no significant difference in the feed conversion ratio of piglet from group I (2.85 ± 0.08), group II (2.69 ± 0.13), group III (2.73 ± 0.03), and group IV (2.69 ± 0.07). Keywords— feed conversion ratio, feed intake, mineral nano particles, live weight gain.

添加矿物纳米颗粒对断奶仔猪生长的影响

本试验旨在通过对仔猪的活增重、总采食量和饲料系数进行评估，以评价添加矿物纳米颗粒对仔猪生长的影响。选取25日龄断奶杜洛克-长约克郡仔猪240头，随机分为4个处理组和1个对照组。ⅰ组仔猪饲喂在基础饲粮中添加1.6 mg/kg nMn、20 mg/kg nFe、2 mg/kg nCu、0.1 mg/kg Co、0.1 mg/kg nSe和20 mg/kg nZn的试验饲粮。第二组、第三组和第四组的纳米矿物含量分别是第一组的2倍、4倍和8倍。结果表明，矿物纳米颗粒添加浓度越高(III组和IV组)，仔猪的活增重越高。IV组仔猪的活增重最高(36.68±0.34 kg) (P < 0.01)。矿物纳米颗粒添加组的饲料系数均低于对照组。仔猪的饲料系数与ⅰ组(2.85±0.08)、ⅱ组(2.69±0.13)、ⅲ组(2.73±0.03)、ⅳ组(2.69±0.07)差异不显著。关键词:饲料系数，采食量，矿物纳米颗粒，活增重
