摘要/Abstract

摘要： 试验旨在研究饲粮中添加葡萄籽原花青素对不同阶段猪生长性能的影响。试验选取48头体重相近的“杜×长×大”三元杂交猪，随机分为4组，每组3个重复，每个重复4头猪。试验分3个生长阶段进行，对照组始终饲喂基础饲粮，试验组在第Ⅰ阶段（断奶仔猪阶段）的基础饲粮中分别添加50、100、150 mg/kg的GSPs，第Ⅱ阶段（生长猪阶段）分别添加100、150、200 mg/kg的GSPs，第Ⅲ阶段（育肥猪）分别添加150、200、250 mg/kg的GSPs进行饲喂。结果发现，在断奶仔猪阶段，饲料中添加100 mg/kg的GSPs显著提高了ADG和ADFI（P<0.05）；在生长猪阶段，饲料中添加150 mg/kg的GSPs显著提高了ADG和ADFI，显著降低了F/G（P<0.05）；在育肥猪阶段添加GSPs没有显著的促进作用，添加250 mg/kg的GSPs反而降低了育肥猪的生长性能。试验表明不同生长阶段猪饲料中添加适量的GSPs对断奶仔猪和生长猪的生长性能有一定的促进作用。
