摘要

在使用国外鸡种生产高产杂交鸡时,根据现有饲料原料(包括本地饲料原料)制定有效的饲养方案是一个亟待解决的问题。这项研究的目的是研究蛋鸡的生产性状,并评估不同饲养阶段不同饲料配方的饲养效率。在这项工作中,我们对 Lohmann-LSL-Classic 杂交种工业鸡群的蛋鸡进行了科学和农场试验。在第一组中,我们改变了企业采用的饲料配方,用于 Lohmann-LSL-Classic 杂交鸡的分阶段饲养。在第 2 组中,饲料配方 PK-1-1PD 增加到 35 周,以保持蛋鸡高水平的产蛋强度并获得最大的鸡蛋数量。第二阶段配合饲料饲喂 13 周,PK-1-3PD 配方的饲喂时间计划为 9 周。第 3 组的目标是通过对第 1 和第 2 阶段饲料配方的饲喂时间进行显著的重新分配,降低产蛋的主要成本。第 3 组出售鸡蛋和肉的利润最高,达到 493.19 万卢布,比第 2 组和第 1 组分别高出 2300.3 万卢布和 464.84 万卢布。第三组生产食用蛋和肉的利润率也较高,达到 16.03%。研究结果表明,在使用 Lohmann-LSL-Classic 杂交工业化鸡群的蛋鸡生产可食用鸡蛋时,阶段饲养计划中的配合饲料配方的饲喂时间应如下:PK-1-1PD - 10 周,PK-1-2PD - 40 周,PC-1-3PD - 7 周。

Efficiency of egg poultry farming at different durations of different recipes of compound feed feeding
Drawing up eff ective feeding programs based on available feed raw materials, including of local origin is a pressing problem when using foreign selection of chickens in the production of highly productive crosses. The purpose of the research was to study the productive traits of laying hens and evaluate the efficiency of production of edible eggs for diff erent durations of feeding different feed recipes during phase of feeding. During the work a scientifi c and farm experiment was carried out on laying hens of the industrial herd of the cross Lohmann-LSL-Classic. In the 1st group, we used a change in feed recipes adopted at the enterprise for phase feeding of poultry cross the Lohmann-LSL-Classic. In the 2nd group, the feed formulation PK-1-1PD was increased to 35 weeks in order to maintain a high level of intensity of egg production of laying hens and obtain the maximum number of eggs. Phase 2 compound feed was fed for 13 weeks, and the feeding time of the PK-1-3PD recipe was planned at 9 weeks. In the 3rd group, the aim was to reduce the prime-cost of produced eggs due to a signifi cant redistribution in the duration of feeding formulas for feed recipes of phases 1 and 2. Profi t from the sale of eggs and meat was maximum in the 3rd group 49 311,9 thousand rubles, which was higher by 2300,3 and 4648,4 thousand rubles than in the 2nd and 1st groups, respectively. The level of profitability of the production of edible eggs and meat was also higher in the 3rd group and amounted to 16,03 %. It was established during the research that in the production of edible eggs from laying hens of the industrial herd of the cross Lohmann-LSL-Classic the following duration of feeding of compound feed recipes in the phase feeding program should be used: PK-1-1PD – 10 weeks, PK-1-2PD – 40 weeks, PC-1-3PD – 7 weeks.
