摘　　要：研究旨在构建不同性别快大型白羽肉鸡不同生长阶段的净能需要预测模型,并以圣泽901肉鸡为试验动物,在实际生产条件下应用预测模型并验证其精准度和适用性;确定圣泽901肉鸡不同生长阶段适宜净能需要量和能蛋比参数,探究净能指标在肉鸡产业中应用的可行性。试验一:通过析因法和间接测热法测定不同性别AA肉鸡不同生长阶段的维持净能需要(NEm)和生长净能需要(NEp)参数,并构建净能需要相关预测模型。选取0日龄AA肉鸡1200只(公母各半),每个性别处理组6个重复,每个重复100只鸡,进行生长和能量代谢试验,试验共分6批次完成,每批次生长测热4 d,绝食测热2.5 d,根据《爱拔益加(AA)肉鸡饲养管理手册2019》挑选不同日龄阶段达到标准体重的试验鸡2~6只放入代谢室,不同性别试验鸡各6个重复。结果显示:不同性别肉鸡净能需要量预测模型如下:NEm(公)=474.38×BW^(0.7)+3.8535(R^(2)=0.986),NEm(母)=432.75×BW^(0.7)+20.581(R^(2)=0.983),体增重(BWG,公)=0.078×NEI-27.089×BW+7.615(R^(2)=0.810),净能摄入量(NEI,公)=1480.523×BW-586.648×BW^(2)+90.163×BW^(3)+121.660(R^(2)=0.877),BWG(母)=0.063×NEI-13.222×BW+12.042(R^(2)=0.710),NEI(母)=1322.758×BW-486.994×BW^(2)+67.819×BW^(3)+171.171(R^(2)=0.937)。试验二:通过4×2双因子安排的随机试验设计,选取9600只13日龄圣泽901肉鸡,随机分为8组,每组12个重复,每个重复100只,进行三阶段饲养,每阶段试验日粮配制为4个净能水平和8个代谢能水平(1个净能水平vs高低2个代谢能水平)即每阶段8个试验日粮处理。结果显示:随着试验日粮净能水平下降耗料量呈上升趋势,但对肉鸡体重和料肉比均无显著影响(P>0.05),日粮净能固定不变,低代谢能日粮组肉鸡的死淘率显著降低(P<0.05)且校正耗料增重比呈下降趋势,提升欧洲效益指数,表明肉鸡对日粮净能变化的反应比对代谢能更为敏感,净能指标配制肉鸡日粮“节本�This study aimed to develop prediction models for net energy(NE)requirements at different growth stages for fastgrowing white-feathered broilers of different genders,using Sunnzer 901 broilers as experimental animals.The prediction models were applied under actual production conditions to verify their accuracy and applicability.The study determined the appropriate NE requirements and NE to crude protein(NE∶CP)ratios for different growth stages of Sunnzer 901 broilers,and explored the feasibility of using NE indicators in the broiler industry.In Experiment 1,factorial methodology and indirect calorimetry were used to measure the NE requirements for maintenance(NEm)and NE requirements for production(NEp)at different growth stages for Arbor Acres(AA)broilers of different genders,and relevant prediction models for NE requirements were developed.A total of 1200 AA broilers at 0 days of age,with equal numbers of males and females,were selected and divided into six replicates per gender,with 100 birds per replicate,for growth and energy metabolism trials.The experiments were conducted in six batches,with four days of growth calorimetry and 2.5 days of fasting calorimetry per batch.According to the Arbor Acres Broiler Management Guide 2019,2 to 6 broilers of different ages that met the standard body weight were selected and placed in metabolic chambers,with six replicates for each gender.The results showed that the prediction models for NE requirements for broilers of different genders were as follows:NEm(male)=474.38×BW^(0.7)+3.8535(R^(2)=0.986),NEm(female)=432.75×BW^(0.7)+20.581(R^(2)=0.983),BWG(male)=0.078×NEI-27.089×BW+7.615(R^(2)=0.810),NEI(male)=1480.523×BW-586.648×BW^(2)+90.163×BW^(3)+121.660(R^(2)=0.877),BWG(female)=0.063×NEI-13.222×BW+12.042(R^(2)=0.710),NEI(female)=1322.758×BW-486.994×BW^(2)+67.819×BW^(3)+171.171(R^(2)=0.937).In Experiment 2,a randomized experimental design with a 4×2 factorial arrangement was used,9,60013-day-age Sunnzer 901 broilers were selected and randomly dividied them into
