【摘要】：研究旨在比较黄羽肉鸡利用不同产地玉米的生物学效价。选择9个不同产地来源的玉米,测定总代谢能(GE)、粗蛋白(CP)和氨基酸(AA)含量。选用200只25日龄中速型黄羽肉鸡,随机分为10个处理组,每组10个重复,每个重复2只鸡。采用套算法和全收粪法,测定9个产地玉米的表观代谢能(AME)、CP、AA利用率。结果:黄羽肉鸡对9个产地玉米的AME、CP平均利用率分别为13.50 MJ/kg、49.14%,玉米GE和CP变异系数分别为1.52%和3.34%,13种AA变异系数高于10%。9个产地玉米AME为:肥城乌克兰枣庄洛阳东北阜阳沈丘偃师湖北;CP消化率为:阜阳东北乌克兰湖北枣庄洛阳肥城沈丘偃师;AA消化率占前三位的个数:乌克兰东北湖北阜阳枣庄沈丘肥城洛阳偃师。结果表明:中速型黄羽肉鸡的玉米代谢能值低于其它鸡种;相对于GE、CP,玉米AA变异程度较大;黄羽肉鸡对东北和乌克兰玉米的AME和营养物质利用率较高。
[Abstract]:The purpose of this study was to compare the biological titers of maize from different habitats in yellow broilers. Total metabolic energy (TME), crude protein (CPP) and amino acid (AA) contents were determined in 9 maize from different habitats. 200 25 days old yellow broilers were selected as middle speed yellow feathered broilers. They were randomly divided into 10 treatment groups, 10 replicates in each group, and 2 chickens in each replica. The average utilization rate of AMEN CP for maize from 9 producing areas was 13.50 MJ / kg ~ (-1), respectively. The variation coefficients of GE and CP were 1.52% and 3.34 ~ (13) AA, respectively. The CV of AMEN was higher than that of 10.9. The digestibility of CP in Shenqianshi of Fuyang, northeast of Luoyang, Zaozhuang, Ukraine, is: the digestibility of CP in Shen Qianshi of Luoyang City, Hubei Province, northeast of Fuyang; the number of digestibility of AA in Shen Qianshi of Luoyang City, Zaozhuang, Hubei Province, northeast of Fuyang; In Fuyang Zaozhuang Shenqiu Feicheng Luoyang Yanshi the results showed that the medium speed yellow feather broiler had lower maize metabolic energy than other chicken breeds. The variation of AA in maize was higher than that of GEP, and the utilization rate of AME and nutrient in yellow feather broiler was higher than that in Northeastern and Ukrainian maize.
