This study evaluated the effects of dietary micelle piperine (MP) supplementation on growth performance, nutrient digestibility, meat quality, and physiological responses in broiler chickens. A total of 640 one-day-old Ross 308 broilers (initial body weight: 44.16 ± 1.06 g) were randomly assigned to one of five dietary treatments for a 35-day feeding trial. Each treatment included eight replicate pens with 16 birds per pen. The experimental diets were based on a common basal diet and consisted of a control diet (CON; 0% MP) and four treatment diets supplemented with increasing levels of micelle piperine (MP): 0.02% (TRT1), 0.04% (TRT2), 0.06% (TRT3), and 0.08% (TRT4). Results demonstrated that dietary MP supplementation significantly increased body weight gain (BWG) from day 21 to 35 and linearly improved final body weight and overall BWG throughout the experimental period (P < 0.05). Nitrogen digestibility tended to improve with increasing MP levels (P < 0.10). Among blood profile, blood urea nitrogen (BUN) tends to decrease with increasing MP levels (P <0.01). However, MP supplementation had no significant effects on meat quality attributes (P > 0.05). In conclusion, dietary inclusion of micelle piperine improved growth performance and showed a tendency to enhance nitrogen digestibility and decrease BUN in broilers, without adversely affecting physiological status and meat stability.
本研究评估了日粮添加微胶粒胡椒碱（MP）对肉鸡生长性能、养分消化率、肉质和生理反应的影响。总共640只1日龄罗斯308肉鸡（初始体重：44.16±1.06克）被随机分配到五种日粮处理之一，进行为期35天的饲养试验。每个处理包括8个重复栏，每栏16只鸡。试验日粮以普通基础日粮为基础，由对照日粮（CON；0%MP）和四种添加不同水平微胶粒胡椒碱（MP）的处理日粮组成：0.02%（TRT1）、0.04%（TRT2）、0.06%（TRT3）和0.08%（TRT4）。结果表明，日粮添加MP显著提高了第21天至35天的体重增加（BWG），并在整个试验期内线性改善了末体重和总体BWG（P<0.05）。氮消化率随着MP水平的增加有提高的趋势（P<0.10）。在血液指标中，血尿素氮（BUN）随着MP水平的增加有下降的趋势（P<0.01）。然而，添加MP对肉质特性没有显著影响（P>0.05）。总之，日粮中添加微胶粒胡椒碱可改善肉鸡的生长性能，并有提高氮消化率和降低BUN的趋势，且不会对生理状态和肉的稳定性产生不利影响。
