日粮添加大麻籽粕对生长肥育猪生产性能和肉品质的影响

 试验旨在研究日粮中添加不同水平大麻籽粕对生长育肥猪生产性能及猪肉品质的影响。选用体重约35 kg猪216头，随机分为4个处理，每个处理6个重复，每个重复9头猪。在等能等氮条件下，大麻籽粕添加水平为35~60 kg（0，4%、8%、12%）；60～110 kg（0、8%、12%、6%）。结果表明：（1）大麻籽粕的不同添加水平均未显著影响生长肥育猪的日增重、日采食量和饲料利用率（P＞0.05）；（2）不同添加水平的大麻籽粕对猪肉品质的影响不显著（P＞0.05）；（3）肌肉、肝、血清和血浆中均未检出四氢大麻酚、大麻二酚和大麻酚。大麻籽粕作为蛋白质饲料资源，可部分替代豆粕，安全地应用于生长肥育猪生产中。

Effect of Supplementation with Dietary Hempseed Meal on Growth Performance and Meat Quality in Growing-finishing Pigs

The experiment was conducted to investigate the effect of dietary hempseed meal levels on growth performance and meat quality in growing-finishing pigs.Two hundred and sixteen pigs with initial body weight of 35 kg were randomly designed to 4 groups with 6 replicates in each group and 9 piglets in each replicate.All pigs were given isocaloric and isonitrogen diets,and supplementation with different levels of hempseed meal were 0,4%,8%,12% for 35～60 kg and 0,8%,12%,16% for 60-110 kg,respectively.The results showed as follows:(1) Supplementation with different level hempseed meal had no significant effects on growth performance,daily gain of weight,daily feed intake and feed conversion during the whole stage(P>0.05).(2) No significant difference was found in porcine meat quality(P>0.05).(3)Tetrahydrocannabinal(THC),canna-bidiol(CBD) and cannabinol(CBN) were not detected in liver,muscle,plasma and serum.As a new protein feed resource,hempseed meal could be safely used to partly replace soybean meal in diet of growing-finishing pigs.
