【摘要】：【目的】研究63~105日龄雌性皖南三黄鸡维持和增重的代谢能(ME)及粗蛋白质(CP)需要量,为其饲养标准的制订提供参考数据。【方法】选取128只63日龄雌性皖南三黄鸡随机分为4组,每组4个重复,每个重复8只,单独笼养,分别饲喂100%,80%,60%和40%(接近维持需要)自由采食量的日粮,105日龄屠宰,运用比较屠宰法评估ME和CP维持需要量。选取48只63日龄雌性皖南三黄鸡随机分为6组,每组8只,单独笼养,自由采食,分别于70,77,84,91,98和105日龄屠宰,测定体粗蛋白质和体能量含量,计算增重的ME和CP需要量。【结果】63~105日龄雌性皖南三黄鸡每千克代谢体质量维持ME需要量为357.50kJ,CP为1.61g,体质量每增加1g ME需要量为64.40kJ,CP需要量为1.20g。【结论】确定了63~105日龄雌性皖南三黄鸡ME、CP的日需要量分别为792.30kJ和11.53g,饲粮的ME、CP营养需要量分别为10.60 MJ/kg和15.42%。
[Abstract]:[objective] to study the requirement of MEM and CP for maintaining and gaining weight of 63 ~ 105 days old female Wannan Sanhuang chickens, and to provide reference data for the establishment of feeding standard. [methods] 128 63-day-old female Wannan Sanhuang chickens were randomly divided into 4 groups. There were 4 replicates in each group, 8 repeats in each group, which were raised in captivity alone, and fed with 100% and 40% (close to the need for maintenance) free feed intake respectively. The ME and CP maintenance requirements were evaluated by comparative slaughter method at 105 days old. Forty-eight 63-day-old female Wannan Sanhuang chickens were randomly divided into 6 groups, 8 in each group, single cage, fed freely, slaughtered at the age of 70, 777, 84, 91, 98 and 105 days, respectively, to determine body crude protein and body energy content. The ME and CP requirements for weight gain were calculated. [results] the ME requirement per kg metabolic body mass of female Wannan Sanhuang chickens aged 63 ~ 105 days was 357.50 kJ / kg CP was 1.61g, and the CP requirement for each increase of body weight was 64.40kJ ~ (-1) CP requirement was 1.20g. [conclusion] The daily 792.30kJ and 11.53g of 792.30kJ and the nutritional requirements of dietary MECP-were 10.60 MJ/kg and 15.42 MJ/kg, respectively.
