摘要

本试验旨在研究不同锌源和水平对断奶仔猪生长性能及血清、粪中锌含量的影响。锌源为2种新型氧化锌，分别是以包合技术制成的包合分子氧化锌和以硬脂酸包被的氧化锌。选取250头24日龄平均体重为（6.74±0.35）kg的"杜×长×大"断奶仔猪，随机分为5组，每组5个重复，每个重复10头猪（公母各1/2）。5组分别为对照组（基础饲粮+2 250 mg/kg普通氧化锌，以锌计，下同）、包合分子氧化锌300组（基础饲粮+300 mg/kg包合分子氧化锌）、包合分子氧化锌600组（基础饲粮+600 mg/kg包合分子氧化锌）、包被氧化锌300组（基础饲粮+300 mg/kg包被氧化锌）、包被氧化锌600组（基础饲粮+600 mg/kg包被氧化锌）。预试期3 d，正试期14 d。结果显示：1）与对照组相比，各试验组的末重、平均日采食量、平均日增重、料重比以及腹泻率均无显著差异（P>0.05）。与包被氧化锌组相比，包合分子氧化锌组的平均日增重显著提高（P<0.05），平均日采食量有提高趋势（0.05 < P < 0.10）。2）与对照组相比，各试验组的血清锌含量分别降低了62.01%、39.94%、56.17%和48.70%；粪锌含量分别是对照组的0.25倍、0.41倍、0.31倍和0.32倍，均差异显著（P<0.05）。综上，300或600 mg/kg的包合分子氧化锌和包被氧化锌与高剂量（2 250 mg/kg）氧化锌在生长性能方面可达到同等效果，且粪锌排放显著降低。

Abstract

The purpose of this experiment was to study the effects of different zinc sources and levels on growth performance and content of zinc in serum and feces of weaned piglets. Two new types of zinc oxide were the inclusion molecular zinc oxide which made by inclusion technology and the zinc oxide which coated with stearic acid. A total of 250 twenty-four-day-old "Duroc×Langdrance×Large White" weaned piglets with body weight of (6.74±0.35) kg were randomly divided into 5 groups:control group (basic diet+2 250 mg/kg normal oxidation zinc, as zinc count, the same as below), inclusion molecular zinc oxide 300 group (basic diet+300 mg/kg inclusion molecular zinc oxide), inclusion molecular zinc oxide 600 group (basic diet+600 mg/kg inclusion molecular zinc oxide), coated zinc oxide 300 group (basic diet+300 mg/kg coated zinc oxide) and coated zinc oxide 600 group (basic diet+600 mg/kg coated zinc oxide), and each group contained 5 replicates and each replicated contained 10 pigs (half male and half female). The pre-experimental period lasted for 3 days, and the experimental period lasted for 14 days. The results showed as follows:1) compared with the control group, the final body weight, average daily feed intake, average daily gain, feed conversion ratio and diarrhea rate of experimental groups had no significant differences (P>0.05). Compared with the coated zinc oxide groups, the average daily gain of inclusion molecular zinc oxide group was significantly increased (P<0.05), and the average daily feed intake showed an increasing trend (0.05<P<0.10). 2) Compared with the control group, the serum zinc contents of experimental groups were decreased by 62.01%, 39.94%, 56.17% and 48.70%, respectively; the faecal zinc contents were 0.25 fold, 0.41 fold, 0.31 fold and 0.32 fold of the control group, and there were all significant difference (P<0.05). In conclusion, 300 or 600 mg/kg inclusion molecule zinc oxide and coated zinc oxide both can achieve the same effects as high dose (2 250 mg/kg) zinc oxide on growth performance, and the fecal zinc emission reduced significantly.
