| 摘 要： | 试验研究择食饲喂对肉鸡胴体品质、胃肠道发育的影响。144羽22日龄艾维茵(Avian)肉鸡随机分成3个处理,每个处理4重复,每重复12羽,分别饲喂粉碎玉米+浓缩料、豆粕+平衡料的试验日粮和基础全价对照日粮,每处理均设两个食槽。结果表明:①择食饲喂玉米+浓缩料可显著促进肉鸡胃肠道发育(P<0.05),改善肉鸡的健康状况;②择食饲喂对肉鸡胴体品质的影响差异不显著(P>0.05),但择食饲喂玉米组能蛋比较高,腹脂率偏高。

| Abstract: | The experiment was conducted to study the effect of choice feeding on growth performance ,carcass quality and development of gastrointestinal tract of 22～49d broilers.One hundred forty four heads of 22d old Avian broilers were randomly allocated to 3 groups with each group including 4 replicates and 12 birds per replicate. Three feeding systems, which had based on the same nutrient levels, were offered to the 3 groups.Ground corn+protein concentrate(G+P), soybean meal +balanced diet(S+B) and complete diet (control) were fed respectively, with 2 troughs each replicate. The results showed:①Choice feeding G+P improved gastrointestinal development (P<0.05) and health status.②Choice feeding had no significant effect on carcass quality(P>0.05) except a little increasing with abdominal fat ratio in broilers feeding with G+P, for the higher ratio between energy and crude protein contents of the practical diets in choice feeding groups. |
