摘要: 为研究皖西白鹅对常用蛋白饲料原料豆粕、菜籽粕及DDGS的氨基酸标准回肠消化率(SIAAD),选取体重相近的56日龄皖西白鹅288只,随机分为24个饲喂栏,每个饲喂栏12只(公、母各半),试验期为35 d,0~28 d为预饲期,全部饲喂相同基础日粮;29~35 d为试验期,分别饲喂待测饲粮和无氮饲粮6 d,每种饲粮6个饲喂栏(重复),第35天早上饲喂前采集回肠食糜并测定食糜中的氨基酸含量。结果显示:豆粕、菜籽粕和DDGS的平均SIAAD分别为88.30%、81.17%、88.99%,且豆粕和DDGS平均SIAAD显著(P<0.05)高于菜籽粕。豆粕中氨基酸的SIAAD如下:赖氨酸(Lys)81.27%、蛋氨酸(Met)95.14%、苏氨酸(Thr)85.08%、缬氨酸(Val)88.25%、亮氨酸(Leu)88.20%、异亮氨酸(Ile)87.33%、苯丙氨酸(Phe)91.66%、组氨酸(His)87.77%和精氨酸(Arg)92.18%;菜籽粕氨基酸的SIAAD如下:Lys 75.19%、Met 87.87%、Thr 82.96%、Val 84.25%、Leu 83.19%、Ile 81.94%、Phe 86.08%、His 84.39%和Arg 83.10%;DDGS 中氨基酸的SIAAD如下:Lys 83.74%、Met 94.59%、Thr 90.85%、Val 91.97%、Leu 93.67%、Ile 91.38%、Phe 94.73%、His 90.59%和Arg 94.09%。该试验结果为豆粕、菜籽粕和DDGS在皖西白鹅饲粮上的高效利用和合理配制低氮饲粮提供数据参考。

Abstract: In order to study the standardized ileal amino acid digestibility (SIAAD) of common protein feed ingredients including soybean meal, rapeseed meal and DDGS in Wanxi white goose, a total of 288 56-day-old Wanxi white geese of similar weight were selected and randomly divided into 24 feeding pens with 12 geese for each feeding pen (6 males and 6 females). The whole test period was 35 d, 0-28 d was the pre-feeding period, all geese were fed with the same basal diet; 29-35 d was the test period, the geese were fed separately with the testing diets and nitrogen-free feed for 6 days, and there were 6 feeding pens for each diet. The ileal chyme of each goose was collected before feeding on the 35th day, and the amino acid content in the chyme was determined. The results showed that the average SIAAD of soybean meal, rapeseed meal and DDGS were 88.30%, 81.17% and 88.99%, respectively, and the average SIAAD of soybean meal and DDGS were significantly (P<0.05) higher than that of rapeseed meal. The SIAAD of soybean meal were as follows:lysine (Lys) 81.27%, methionine (Met) 95.14%, threonine (Thr) 85.08%, valine (Val) 88.25%, leucine (Leu) 88.20%, ileucine (Ile) 87.33%, phenylalanine (Phe) 91.66%, histidine (His) 87.77% and arginine (Arg) 92.18%; the SIAAD of rapeseed meal were as follows: Lys 75.19%, Met 87.87%, Thr 82.96% , Val 84.25%, Leu 83.19%, Ile 81.94%, Phe 86.08%, His 84.39% and Arg 83.10%; the SIAAD of DDGS were as follows: Lys 83.74%, Met 94.59%, Thr 90.85%, Val 91.97%, Leu 93.67%, Ile 91.38%, Phe 94.73%, His 90.59% and Arg 94.09%. The results of this experiment provide reference for the efficient utilization of soybean meal, rapeseed meal and DDGS in the diet of Wanxi white goose and reasonable preparation of low-nitrogen diet.
