摘要: 本文对白羽蛋鸡慢羽品系不同羽型的分布比例及其生产性能进行了研究。在观察和测定1203只出壳雏鸡中,按四种羽型分类法,以倒长型(S1)所占比例最大(72.7%),其次为未出型(S2)(19.64%)、等长型(S3)(6.7%),最少是微长型(S4)(仅占1%)。统计慢羽母鸡的结果表明,四种羽型鸡在0、20周龄生长发育差异不大,各周龄的体重顺序从大到小均依次为做长型、等长型、倒长型和未出型,但在谷羽型之间一般均未达到统计上的差异。开产日龄和蛋重在各羽型鸡之间无显著差异(p>0.1),43周龄产蛋量除等长型显著多于做长型外(P<0.1),其它羽型间未达到统计上的显著性(P>0.1)。

Abstract: This paper is about the distribution of different slow-feathing types and their performences of the slow-feathering pure line of white chicken layers. 1203 day-old chicks were identified and divided into four groups according to their slow feathering types:1. the primaries, shorter than primary-coverts(S1), are the highest(72.7%), the primaries, not extended out(S2), are the second(19.4%), 3. the same in length of primaries and primary-coverts is the third(6.7%) and 4. the primaryes, longer than primary-coverts within 2mm(S4), are the lowest(1%). The result from female checkens showed that the difference of growth and development from the age of day old to twenty weeks old among the four types was not obvious. In each weed, their body weight from the highest to the lowest is S4, S3, S1 and S2, but their difference does not reach the significant level. There is no significant difference either in the age of first egg and egg size among the four slow-feating types(P>0.1). The egg production in 43 weeks of age of S3 is signifieantly higher than that of the S4(P<0.1), but the diffirence in all the others is not significant(P>0.1).
