Abstract

Improving the productive performance of commercial beef cattle obtained by crossbreeding locally improved cattle with purebred beef animals (Kazakh Whiteheaded, Hereford, Angus, etc.) will make it possible to increase beef production by enhancing the growth and development potential of crossbred ani mals and bringing them to a live weight of 420–450 kg or more at a young age. During the grazing period, the increase in the average daily weight gain of calves was achieved through supplementary feeding during the period of pasture burnout, which contributed to a more complete realization of their growth and development in the post-milk period. An analysis of research results in our country and abroad showed that increasing the quantity and quality of beef is possible through intensifying the use of dairy and dual-purpose (dairy-beef) fat tening cattle, as well as through the accelerated development of beef cattle breeding. Research results showed that Hereford cattle, when combined with various breeds, are characterized by a high degree of combining ability. Crossbreds with a proportion of Hereford blood surpass their maternal breed counterparts in terms of meat productivity indicators. Hereford cattle are used both in industrial crossbreeding and in the development of new breeds. In the experiment, growth and development of the bull calves were monitored through month ly weighing and determination of average daily gain. One of the key conditions for the normal development of young stock is a targeted feeding ration corresponding to different growth periods. Therefore, in order to assess the effect of feeding level on the growth energy of Hereford bull calves, studies were conducted under farm conditions. Hereford crossbreds exceeded their peers in slaughter weight by 22.2 kg (8.62 %), indicating their higher potential meat productivity.
