Abstract Effects of dietary supplementation of coated omega-3 fatty acids (n-3FAs) on the growth performance, apparent total tract digestibility (ATTD) of nutrients, fecal scores, serum IgG and haptoglobin concentrations, and selected faecal microbial in weaning pigs was evaluated in the present study In total, 160 piglets [(Landrace x Yorkshire) x Duroc, body weight =7.42 ± 1.21 kg] were randomly assigned in a 6-week trial to four treatments: Treatments consisted of basal diet and basal diet supplemented with graded levels (5g/kg, 10g/kg and 15g/kg) of coated n-3FAs, The supplementation of basal diet with increasing levels of coated n-3FAs linearly increased the average daily gain of pig during week 1, 3 and during overall experiment period, the gain feed ratio (G/F) was linearly increased during the overall experimental period, the ATTD of dry matter (DM) and nitrogen (N) was also linearly increased at the end of experiment (P

包裹omega-3多不饱和脂肪酸在基础日粮中对改善断奶仔猪生长性能、营养物质消化率、粪便乳酸菌计数和粪便评分的补充作用

摘要 日粮中添加包膜 omega-3 脂肪酸 (n-3FAs) 对断奶仔猪生长性能、营养素表观全消化道消化率 (ATTD)、粪便评分、血清 IgG 和结合珠蛋白浓度以及选定的粪便微生物的影响进行了评估。在本研究中，总共有 160 头仔猪 [(Landrace x Yorkshire) x Duroc，体重 =7.42 ± 1.21 kg] 在为期 6 周的试验中被随机分配到四种处理：包衣 n-3FAs 水平（5g/kg、10g/kg 和 15g/kg），在基础日粮中添加包衣 n-3FAs 水平线性增加猪在第 1、3 周和整个实验期间的平均日增重在整个实验期间，增益饲料比（G / F）线性增加，干物质（DM）和氮（N）的ATTD在实验结束时也呈线性增加（P
