Abstract A total of 45 multiparous sows (Landrace × Yorkshire, average parity is 4.2) and their piglets were used in a 35 days experiment to evaluate the effects of coated omega-3 polyunsaturated fatty acid (COF) on colostrum and milk immunoglobulin G (IgG) concentrations and fatty acid composition, and piglet growth performance. Sows were randomly allocated to three treatments with 15 replications per treatment. Dietary treatments were as follows: CON, basal diet; COF1, CON + 2.5 g/kg of COF; (3) COF2, CON + 5.0 g/kg of COF. No significant (P > 0.05) responses were observed for reproductive performance parameters such as litter size, lactating average daily feed intake, body weight (BW) loss, backfat thickness loss, and estrus interval days. A significant linear increase (P

亚麻籽油中包裹的omega-3脂肪酸对母猪免疫球蛋白G浓度和仔猪断奶前性能有积极影响

摘要 对 45 头经产母猪（长白猪 × 约克夏猪，平均胎次为 4.2）及其仔猪进行了 35 天的实验，以评估包被的 omega-3 多不饱和脂肪酸（COF）对初乳和牛奶免疫球蛋白 G（IgG ) 浓度和脂肪酸组成，以及仔猪生长性能。母猪被随机分配到三个处理组，每个处理组重复 15 次。饮食治疗如下：CON，基础饮食；COF1、CON + 2.5 g/kg COF；(3) COF2、CON + 5.0 g/kg COF。对于繁殖性能参数，如窝产仔数、哺乳期平均每日采食量、体重 (BW) 损失、背膘厚度损失和发情间隔天数，未观察到显着 (P > 0.05) 响应。显着的线性增加（P
