Abstract

The advocates of standard bred poultry are undoubtedly right in insisting that standard bred poultry may be good layers. This is abundantly demonstrated by numerous high class standard bred birds that are also high layers. I know from personal experience of several strains of standard bred Rhode Island Reds that can be depended upon to produce several birds out of each hundred, that will lay better than 200 eggs.

I have great faith, too, that it is possible to combine in one strain, the qualities of high average production, as distinct from high individual production, and the qualities demanded by the standard. If an average of 150 eggs per bird is considered high, I feel confident that some, at least, of the strains mentioned above, without further selection, can be handled so as to come very close to such an average.

High and low, in relation to egg production are …

从研究者的角度看鸡蛋生产和标准饲养家禽
标准饲养家禽的倡导者坚持认为标准饲养的家禽可能是好的蛋鸡,这无疑是正确的。这在许多高级别标准繁殖的鸟类身上得到了充分的证明,这些鸟类也是高水平的。根据我个人的经验,我知道有几种标准品种的罗德岛红鸡,每一百只鸡中有几只能下200多只蛋。我也深信,有可能把高平均产量(区别于高个人产量)的品质和标准生产所要求的品质结合在一个品系中。如果每只鸟平均产150个蛋被认为是高的,我相信,至少上面提到的一些菌株,不需要进一步的选择,就可以处理得非常接近这个平均值。与产蛋量有关的高低是……
