摘　　要：选同一批体况相近断奶（长×大）二元仔猪238头,分成对照组和试验组,每组3个重复,每个重复38-42头仔猪,公母各半。对照组日粮不含酵母源产品,试验组日粮添加0.1%外源核苷酸产品（核苷酸≥20%）。正式试验期10 d。结果表明：与对照组相比,试验组日均采食量（ADFI）显著提高19.9%（P〈0.01）,腹泻频率显著降低67.56%（P〈0.05）,平均日增重提高（ADG）1.4%（P〉0.05）,料重比（F/G）提高3.67%（P〉0.05）。可见日粮添加0.1%外源核苷酸产品能有效提高断奶仔猪生长性能。A total of 238 early weaning piglets（Landrace X Large White,half gilt and half barrow） of the same batch with nearly same weight were selected and allotted randomly into two groups with 3 replicates of 38 ？42 per each.Control diet contained no yeast-derived product, treatment diet was supplemented with 0.1% commercial nucleotide product（nu- cleotide ≥ 20% ） .The trial lasted for 10 days.Results showed that compared with the control group, average daily feed in-take （ADFI）and average daily gain （ADG） of the treatment improved respectively by 19.9% （P 〈 0.01） and 1.4% （P 〉 0.05） ,diarrhea frequency significantly decreased by 61.56%{P 〈 0.05） ,and as a contrast,feed/gain （F/G）of the treatment increased by 3.61% （P 〉 0.05）.As a conclusion, adding 0.1% commercial nucleotide product could effectively improve growth performance in weaning piglets.
