TECHNOLOGICAL SCHEMES FOR GROWING HEIFERS FOR THE PURPOSE OF EARLY FURTHER INSEMINATION OF YOUNG-NAC AT 12 MONTHS OF AGE IN "POBEDA" LLP, PAVLODAR REGION

Abstract

The object of research was the young of the Holstein breed in LLP "Victory" in Pavlodar region. This work was carried out within the framework of the state program: Sustainable development of the agro-industrial complex and safety of agricultural products. Subsection: Development of animal husbandry based on  ntensive technologies: BR10764965 Development of tech ologies for keeping, feeding, growing and repro-duction in dairy cattle breeding based on the use of adapted resource-energy-saving and digital technologies for various natural and climatic zones of Kazakhstan. Studies have been carried out to study various schemes for growing heifers for the purpose of early fruitful insemination of young animals at the age of 12-15 months. The diet of calves included, depending on age, colostrum and whole milk, water, pre-starters, hay and a mixed diet. A prototype feed sample with ToU premix was made. During the experiment, observations were made of the helth status of calves, accounting for feed consumption. Studied the growth and development of calves. The data of monthly weighing of animals, live weight gain and average daily weight gain of calves are given. Young animals of the control group reached a live weight of 380 16 kg on August 04, 2022. 9 days earlier the given date, the calves of the second experi-mental group reached the same live weight, that is, on July 26, 2022. The animals of the III experimental group, which received 285 liters of milk according to the scheme of drinking, reached 380 kg of weight on July 18, 2022, which is 17 days earlier than the calves of the control group.
