The purpose of the research was to investigate the effects of including potato peels (PP) in broilers diet with exogenous enzymes supplementation on feed intake (FI), body weight gain (BWG), nutrient digestibility and carcass parameters. For this purpose, five iso-caloric and iso-nitrogenous rations were formulated with different levels of PP (0, 5, 10, 15 and 20%). Experimental diets were supplemented with a blend of exogenous enzymes (Xylanase, Mannanase, Protease, Cellulase). A total of four hundred male broiler chicks (day old) of 38 ± 3 gram were randomly distributed into 5 experimental groups in such a way that each group had 8 replicates and each replicate had 10 birds. Results revealed that the inclusion of PP @ 5% with exogenous enzymes had similar FI, BWG and nutrients digestibility with control. However, the inclusion of P @ of 10, 15, and 20% with exogenous enzymes in the broiler diet adversely affected the BWG, feed conversion ratio and nutrient digestibility ( < 0.05). Results of carcass parameters were not affected ( > 0.05) by dietary treatments. Based on findings, it is concluded that 5% addition of PP with exogenous enzymes could be practiced in broiler diet without any adverse effect on the performance of commercial broilers.
本研究旨在探讨在肉鸡日粮中添加外源酶的情况下，添加马铃薯皮（PP）对采食量（FI）、体重增加（BWG）、养分消化率和胴体参数的影响。为此，设计了五种等热量和等氮水平的日粮，其中 PP 的水平分别为 0、5、10、15 和 20%。试验日粮添加了一种混合的外源酶（木聚糖酶、甘露聚糖酶、蛋白酶、纤维素酶）。共选用 400 只 38±3 克的雄性肉鸡随机分为 5 个实验组，每个实验组有 8 个重复，每个重复有 10 只鸡。结果表明，添加 5%的 PP 和外源酶具有与对照组相似的 FI、BWG 和养分消化率。然而，在肉鸡日粮中添加 10、15 和 20%的 P 和外源酶会对 BWG、饲料转化率和养分消化率产生不利影响（ < 0.05）。日粮处理对胴体参数没有影响（ > 0.05）。基于这些发现，可以得出结论，在肉鸡日粮中添加 5%的 PP 和外源酶可以在不影响商业肉鸡性能的情况下进行。
