This study was conducted to evaluate the effects of (TM) oil as a total replacement for palm oil and poultry fat in broiler chicken diets on growth performance, nutrient digestibility, pancreatic enzyme activity, selected blood parameters and the lipid fatty acid compositions of liver and breast muscle tissues. A total of 72 seven-day-old female Ross 308 broiler chickens were used. The birds were randomly distributed into three groups with 12 replicates each, using two birds per replicate for 30 days in metabolic cages. The basal diet was supplemented with 5% palm oil, poultry fat or TM oil. There was no effect ( > 0.05) caused by the dietary oil replacement on the birds' performance and apparent nutrient digestibility. Liver size ( = 0.033), the concentration of hepatic triglycerides ( = 0.049) and total cholesterol ( = 0.048) were reduced by TM oil supplementation. Furthermore, TM oil supplementation increased n-3 and n-6 fatty acids ( = 0.006; < 0.001, respectively) in breast muscle tissue. In conclusion, the use of TM oil in broiler chickens' diets did not show any adverse effects on performance, nutrient digestibility and blood biochemical parameters. Moreover, TM oil supplementation improved the fatty acid profiles of liver and breast muscle tissues.
本研究旨在评估在肉鸡日粮中使用（TM）油完全替代棕榈油和家禽脂肪对生长性能、养分消化率、胰腺酶活性、选定血液参数以及肝脏和胸肌组织脂质脂肪酸组成的影响。总共使用了72只7日龄的罗斯308雌性肉鸡。将这些鸡随机分为三组，每组12个重复，每个重复使用2只鸡，在代谢笼中饲养30天。基础日粮分别添加5%的棕榈油、家禽脂肪或TM油。日粮油替代对鸡的生长性能和表观养分消化率没有影响（P>0.05）。添加TM油可降低肝脏大小（P=0.033）、肝脏甘油三酯浓度（P=0.049）和总胆固醇（P=0.048）。此外，添加TM油可提高胸肌组织中的n-3和n-6脂肪酸含量（分别为P=0.006；P<0.001）。总之，在肉鸡日粮中使用TM油对生长性能、养分消化率和血液生化参数没有任何不良影响。此外，添加TM油可改善肝脏和胸肌组织的脂肪酸谱。
