Abstract

One of the poultryman’s biggest problems is to renew the flock. This depends in a large measure upon incubation. To be successful in incubation one must have good, fertile eggs that will develop vigorous chicks. The feeding and care of the breeders will determine very largely the quality of the eggs they will produce.

In determining the efficiency of our breeders we must take into consideration the following factors: feed costs, number of eggs produced, fertility, hatchability, cost to produce a chick, chick mortality, and quality of the chicks.

In the experiment which is here reported all conditions were made as uniform as possible, with the ration as the variable factor. The basal or check grain mixture consisted of six parts of cracked corn, three parts of oats, one part of wheat. The mash mixture was made up of one part each of corn meal, wheat bran, wheat middlings, ground . . .

特定口粮对种猪生产效率的影响
家禽养殖者最大的问题之一是更新家禽群。这在很大程度上取决于潜伏期。要成功孵化,必须有良好的、肥沃的蛋,才能孵出充满活力的小鸡。种鸡的饲养和照料在很大程度上决定了它们所产蛋的质量。在确定育种人员的效率时,我们必须考虑以下因素:饲料成本、产蛋量、生育力、孵化率、小鸡生产成本、小鸡死亡率和小鸡质量。在这里报告的实验中,所有条件都尽可能统一,以比例为可变因素。基础谷物混合物由六份破碎的玉米、三份燕麦和一份小麦组成。土豆泥混合物由玉米粉、麦麸、麦粒、磨碎的面粉各组成一部分。
