Abstract:
The article presents the results of scientific research on the production of lamb in the conditions of the Akmola region. The experiment was conducted on purebred Kazakh short-tailed rough-haired and cross-bred sheep obtained from industrial crossing of Kazakh short-tailed rough-haired queens with sheep- producers of the hampshire breed. Further, the article presents the results of feeding and fattening, as well as the morphological composition of the carcass of sheep of the Kazakh coarse-haired sheep breed of different ages. The object of the study for feeding and fattening were three groups of experimental sheep of the above-mentioned breed, where compound feed was included in the diet of the I experimental group in the form of top dressing, in the II experimental group, grain waste was also used for top dressing, and the control group was kept in the feed without top dressing. Based on the study of the feeding of experimental sheep, it was found that the absolute increase during the feeding period in experimental sheep who received fertilization in the form of compound feed is higher than in their peers, respectively, by 0.2 and 1.49 kg. In terms of morphological and varietal composition, in particular, the number of cuts of grade 1, there was also an advantage of experimental sheep that received fertilization in the form of compound feed compared to their peers, respectively, by 2.3-8.3%. In general, the results of a study on the growth, development and slaughter qualities of experimental sheep, i.e. purebred Kazakh short-tailed rough-haired and crossbred, obtained from crossing with sheep producers of the precocious breed \"hampshire\" showed that from the moment of birth to 2 and 4 months. For example, crossbred sheep were slightly superior to purebred peers in terms of the studied indicators. In particular, the results of feeding sheep of the Kazakh coarse-haired broad-tailed breed from 4 to 6 months, depending on the top dressing.
摘要:
本文介绍了在阿克莫拉地区条件下生产羔羊的科学研究结果。该实验是在纯种的哈萨克短尾粗毛和杂交绵羊上进行的,这些绵羊是从哈萨克短尾粗毛皇后与汉普郡品种的产羊者的工业杂交中获得的。Further,这篇文章介绍了喂养和育肥的结果,以及不同年龄的哈萨克粗毛绵羊品种的绵羊尸体的形态组成。研究对象为上述品种的三组实验羊,其中复合饲料以追肥的形式包含在I实验组的饮食中,在II实验组中,谷物废物也被用于追肥,对照组饲喂不追肥。在实验羊饲养研究的基础上,发现以复合饲料形式接受受精的实验绵羊在喂养期间的绝对增加量高于其同龄人,分别,0.2和1.49公斤。在形态和品种组成方面,特别是,削减1级的数量,与同龄人相比,实验绵羊以复合饲料的形式接受受精也有优势,分别,2.3-8.3%。总的来说,关于生长的研究结果,实验羊的发育和屠宰质量,即纯种的哈萨克族短尾粗毛杂种,从与早熟品种“汉普郡”的绵羊生产者杂交获得的结果表明,从出生到2和4个月。例如,在研究指标方面,杂交绵羊略优于纯种同龄人。特别是,从4到6个月喂养哈萨克粗毛宽尾品种的绵羊的结果,取决于追肥。
