The aim of the study was to examine the effect of pig bile powder supplementation on the digestibility of nutrients, fat digestion and growth performance of starter broilers fed on a high fat diet. A total of 1110, day-old, male broiler chicks (Arbor Acres) were randomly allocated into six treatment groups with five replicates per treatment. The chicks were fed on a corn-soybean meal basal diet with a starter formulation until Day 14, followed by a grower formulation until Day 21. In group 1 (T1), the basal diet contained 30 g/kg crude palm oil whereas the diet used in group 2 (T2) had 60 g/kg crude palm oil. Chicks in group 3 (T3) were fed on T2 diet supplemented with 5.0 g/kg soy lecithin as the positive control. Chicks in groups 4–6 (T4–T6) received diets used in T2, supplemented with 1.25, 2.5 and 5.0 g/kg lyophilised pig bile powder, respectively. On Days 4, 7, 14 and 21, chicks were killed, portal blood was collected and analysed for fatty acids, pancreas collected for measurement of pancreatic lipase activity, bile and jejunal contents for bile acid determination and ileal content for determining digestibility of fat and protein. The results showed (1) there was no difference in bodyweight and feed intake among T2–T6, (2) pancreatic lipase activity of chicks in T4 and T5 was highest in all periods. Total bile acid concentrations in the gall bladder and jejunum in T4 was lower than those in T2 in all periods, and Days 4 and 7, respectively, (3) digestibility of protein and fat in T3 and T4 was higher in all the period than that of T2, T5 and T6, (4) increased fat content in the diet did not cause a significant increase in any fatty acids in the portal plasma when compared T1 and T2. In conclusion, 2.5 g/kg porcine bile powder supplemented in high fat diet increased pancreatic lipase activity and total bile acid concentrations in gall bladder, resulting in increased ileal digestibility of fat and protein.

更正：在高脂肪肉鸡日粮中添加猪胆汁粉与生长性能和营养消化的关系

该研究的目的是检查添加猪胆粉对高脂肪日粮饲喂的雏鸡的营养物质消化率、脂肪消化率和生长性能的影响。总共 1110 只日龄雄性肉鸡 (Arbor Acres) 被随机分配到 6 个处理组，每个处理 5 个重复。在第 14 天之前用玉米豆粕基础日粮喂养小鸡，然后在第 21 天之前使用种植者配方。在第 1 组（T1）中，基础日粮含有 30 g/kg 粗棕榈油，而日粮第 2 组 (T2) 中使用的粗棕榈油为 60 g/kg。第 3 组 (T3) 中的小鸡以 T2 日粮喂养，辅以 5.0 g/kg 大豆卵磷脂作为阳性对照。第 4-6 组 (T4-T6) 中的小鸡接受 T2 中使用的饲料，并添加 1.25、2.5 和 5.0 g/kg 冻干猪胆粉，分别。在第 4、7、14 和 21 天，杀死小鸡，收集门静脉血并分析脂肪酸，收集胰腺用于测量胰脂肪酶活性，胆汁和空肠内容物用于测定胆汁酸，回肠内容物用于确定脂肪和脂肪的消化率。蛋白质。结果表明：（1）T2-T6 之间的体重和采食量没有差异，（2）T4 和 T5 的雏鸡胰脂肪酶活性在所有时期都是最高的。T4各时期胆囊和空肠总胆汁酸浓度均低于T2，第4天和第7天，(3)T3和T4各时期蛋白质和脂肪消化率均高于T2 T2、T5 和 T6，(4) 与 T1 和 T2 相比，饮食中脂肪含量的增加不会导致门静脉血浆中任何脂肪酸的显着增加。总之，在高脂肪饮食中添加 2.5 g/kg 猪胆汁粉可增加胰脂肪酶活性和胆囊中的总胆汁酸浓度，从而增加回肠对脂肪和蛋白质的消化率。
