摘要
用１８０只５６日龄肉用仔珍珠鸡，测定了高温环境（２５～３４℃）条件下，在日粮中添加不同量的ＮａＨＣＯ３ （质量分数分别为０％ ，０．５％ ，１．０％ ，１．５％ ，２．０％ ，２．５％ ）对珍珠鸡肥育期（５６～８４日龄）生产性能及血液ｐＨ 值的影响，基础日粮含 ＭＥ １３．３７ ＭＪ／ｋｇ，ＣＰ１８％ 。结果表明：体增重、采食量、屠宰率、血液ｐＨ 值不受日粮中ＮａＨＣＯ３的显著影响（Ｐ＞ ０．０５），但体增重、采食量、饲料利用率受性别的显著影响（Ｐ＜ ０．０５），母鸡比公鸡的体增重大１８．８％ ，采食量高８．０２％ ，饲料利用率高９．７０％ ，公母鸡间的这种差异在１．５％ ＮａＨＣＯ３
A total of 180 guinea fowls were employed to investigate the effects of different dietary NaHCO 3 supplementation(0,0.5,1.0,1.5,2.0,2.5%)on performance and blood pH in finishing period (56 to 84 d of age)raised under high environmental temperatures ranging from 25～34℃.The basic diet contained 13.37 MJ/kg ME and 18% CP.Results showed that weight gain,feed intake,eviscerated yield and blood pH were not affected( P >0.05)by dietary NaHCO 3 supplementation.However,weight gain,feed intake and feed conversion were significantly affected( P <0.05)by sex.Females showed 18.8% larger weight gain,8.02% greater feed intake and 9.70% lower feed conversion than males.These differences appeared obviously in diet of 1.5% NaHCO 3 supplementation.
