摘要 为了解猪生长激素(pGH)脂质体对育肥猪缓释作用效果,选用体重约50 kg健康去势的长白×大约克公猪24头,随机分成4组,即对照组和3个试验组。对照组每天注射生理盐水,试验一组每天按4 mg的剂量肌肉注射pGH,试验二组每3 d注射12 mg pGH脂质体,试验三组每7 d注射28 mg pGH脂质体,试验期为21 d。结果显示:注射pGH及其脂质体能够提高猪的日增重(P<0.05)和末重,显著降低料重比(P<0.05),试验组血清中胰岛素样生长因子1(IGF-1)水平显著高于对照组(P<0.01);注射生长激素的猪血清中生长激素水平均有不同程度的升高。脂质体的缓释时间可以达到7 d,表明猪生长激素脂质体在促进猪生长发育方面的效果明显。
