【摘要】：本试验旨在研究包被氧化锌替代高剂量氧化锌对35~49日龄仔猪生长性能、腹泻指数及对营养物质消化利用的影响。24头35日龄仔猪随机分为2组,每组6个重复,每个重复2头,普通氧化锌组氧化锌含量为2 500 mg/kg,锌添加量为1 950 mg/kg;包被氧化锌组包被氧化锌含量为1 000 mg/kg,锌添加量为580 mg/kg。结果表明:包被氧化锌组料重比显著低于氧化锌组(P0.05);包被氧化锌组猪只对干物质的表观消化率显著大于氧化锌组(P0.05);腹泻率、粪便级数评分无显著差异(P0.05)。血清铜锌-超氧化物歧化酶、血铜含量无显著差异(P0.05),全血血红蛋白水平、皮毛指数也无显著差异(P0.05)。说明低剂量添加的包被氧化锌提高了35~49日龄仔猪的生长性能和营养物质消化率。
[Abstract]:The purpose of this experiment was to study the effects of coated zinc oxide on growth performance, diarrhea index and nutrient digestibility of 35 ~ 49 days old piglets. 24 piglets of 35 days old were randomly divided into two groups, 6 replicates in each group, 2 piglets per repeat. The content of zinc oxide in zinc oxide group was 2 500 mg / kg, zinc addition was 1 950 mg / kg, zinc oxide content in coated zinc oxide group was 1 000 mg / kg and zinc addition amount was 580 mg / kg. The results showed that the weight ratio of zinc oxide in coated zinc oxide group was significantly lower than that in zinc oxide group. The apparent digestibility of dry matter in the coated zinc oxide group was significantly higher than that in the zinc oxide group, and the diarrhea rate was significantly higher than that in the zinc oxide group. There was no significant difference in fecal grade score (P 0.05), serum copper, zinc and superoxide dismutase (SOD), no significant difference in blood copper content (P 0.05), and the whole blood hemoglobin level. There was no significant difference in fur index (P0.05), which indicated that the growth performance and nutrient digestibility of piglets were increased by adding coated zinc oxide in low dose.
