饲养模式对符离集烧鸡品质的影响

Effect of Different Feeding Modes on the Quality of Fuliji Roasting Chicken

试验研究了不同模式饲养的淮北麻鸡对符离集烧鸡品质的影响。450只56日龄淮北麻鸡分为笼养组、平养组、放养+笼养组、放养+平养组、放养组,每组公母各半。饲养13周后用于加工符离集烧鸡。结果显示:放养组与放养+平养组的公鸡加工成品率较高,分别比平养组高4.86%和4.17%;放养+笼养组、放养组的母鸡加工成品率分别比放养+平养组、笼养组高9.55%、9.16%和7.54%、7.16%;感官综合评定以放养和放养+平养组最好,均显著高于平养组(P<0.05),极显著高于放养+笼养组和笼养组(P<0.01);烧鸡营养成分中,脂肪含量以放养组最低,笼养组最高;风味氨基酸、必需氨基酸的含量以放养+平养组最好,显著高于平养与笼养组(P<0.05)。表明饲养模式对符离集烧鸡的加工成品率、感官评价和营养成分含量均有一定程度的影响,综合各项指标以放养+平养模式饲养的淮北麻鸡加工的符离集烧鸡最优。

The experiment was conducted to study the effect of different feeding modes on the quality of Fuliji roasting chicken. The 56-day-age Huaibei partridge chicken were raised in 5 kinds of feeding modes： caged,floor-reared, free range eombinated with caged, free range eombinated with floor-reared, free range, with 45 cocks and 45 hens respectively per mode. The chickens were raised for 13 weeks to make Fuliji roasting chickens. The results showed that the rates of finished cock product in free range group and free range combinated with floor-reared group were significantly higher than that of floor-reared group by 4.86% and 4.17%;About the rate of finished hen product,free range combinated caged group and free range group were higher than free range combinated floor-reared group by 9.55%, 9.16%, and higher than caged group by 7.54%, 7.16% respectively; sensory evaluation of free range and free range combinated floor-reared groups were significantly higher than that of floor-reared group （P〈0.05）,free range combinated caged group and caged group （P〈0.01）;For the nutritional ingredient of Fuliji roasting chickens,total fat was lowest in free range group and highest in caged group,flavour amino acid and essential amino acid were higher significantly in free range combinated with floor-reared group compared with the groups of floor-reared and caged （P〈0.05）. The results suggested that the feeding mode affected significantly the rate of finished products, sensory evaluation and nutritional ingredient of Fuliji roasting chicken, Huaibei partridge chicken raised in free range combinated with floor-reared mode was the best as the raw material of Fuliji roasting chicken based on comprehensive analysis of the above indexes.
