Nghiên cứu này được thực hiện nhằm đánh giá ảnh hưởng của việc bổ sung nano khoáng trong khẩu phần thức ăn đến sự tăng trưởng của lợn thịt. Tổng số 180 lợn thịt sử dụng cho nghiên cứu này, được chia thành 4 nhóm thí nghiệm và nhóm đối chứng, mỗi nhóm 3 ô, mỗi ô 12 con (tương ứng 3 lần lặp lại). | Ảnh hưởng của bổ sung khoáng nano trong khẩu phần thức ăn đến khả năng sinh trưởng của lợn thịt TAP CHI SINH HOC 2020, 42(1): 125–131 DOI: EFFECTS OF NANO MINERAL-SUPPLEMENTED DIET ON PIG GROWTH Hoang Nghia Son Institute of Tropical Biology, VAST, Vietnam Received 25 December 2019, accepted 10 March 2020 ABSTRACT This paper examined the effects of nano mineral supplementation of diets on the growth of pigs. The total of 180 pigs used for this study were classified into 4 experimental groups and one control group. The results showed that the weight of pigs at the beginning and the end of the experiment was insignificantly different between experimantal and control groups. The same daily gain weight was observed between experimental and control groups. However, the feed conversion ratio (FCR) of four experimental groups I, II, III and IV is ± , ± , ± and ± , respectively, that were lower than of the control groups, . ± . The mineral content of Fe, Cu, Zn and Mn in liver of pigs in all the experimental groups is lower than that in liver of pigs in the control group. In addition, the amount of Fe and Zn metal in urine and feces of the experimental groups is also lower than in the control group. The results of our study showed that the addition of nano minerals in diets for pigs not only reduced the feed conversion ratio in pigs, also decreased the amount of minerals releasing into the environment.
