Increasing the milk productivity of Kazakh jabe horses.
Abstract: The purpose of the study was to determine the milk productivity and chemical composition of the milk of mares of the Kazakh breed of the jabe type (KJ) and the Novoaltay-Kazakh crossbreeds of the 1st generation (NA x KJ) in the conditions of herd keeping. To determine the milk productivity of mares, 2 experimental groups were formed with a total of 30 mares, 15 individuals were selected in each group. The studied animals were formed according to the principle of pairs of analogues in the context of full-age groups from 5 to 11 years. Kazakh horses of the jabe type in the group of experimental mares in milk have an average live weight of 433.5 kg, and are significantly inferior to the Novoaltay-Kazakh crosses (515.3 kg). The body measurements were 142.0-149.0-174.9-18.2 cm in Kazakh horses of the jabe type, and 150.1-157.1-186.7-20.02 cm, respectively, in Novoaltay-Kazakh crossbreeds. According to the results of studies, the milkiness of mares of the Novoaltay-Kazakh crosses for 105 days of lactation averaged 1932 liters or higher by 25.2% (487.2 liters) than the milkiness of mares of the Kazakh breed of the jabe type. As a result of studies on the composition of milk of mares of different genotypes, it was found that in mares of Kazakh jabe, on average, protein and fat indicators compared to Novoaltay-Kazakh crossbreeds were higher by 0.07% and 0.05%. In the course of determining the live weight of mares among the experimental groups, it was found that the Novoaltay-Kazakh crossbreeds, on average, had a higher live weight of 515.3 kg or higher compared to the Kazakh jabe by 81.8 kg (15.8%). Thus, the studies have proved the prospects of using stallions of the Novoaltay breed to increase the milkiness of local Kazakh horses of the jabe type in herd and pasture conditions.

The research focuses on increasing the milk productivity of Kazakh jabe horses as well as examining the chemical composition of their milk. The study revealed that Novoaltay-Kazakh crossbreeds demonstrated higher milk productivity and live weight compared to the native Kazakh breed, suggesting the potential of using Novoaltay breed stallions to enhance milk production.
Objective and Methodology
- The study aims to examine the milk productivity and chemical composition of milk from Kazakh jabe mares and Novoaltay-Kazakh first generation crossbreeds under herd conditions.
- Two experimental groups of 15 mares each, totaling 30 mares, were selected for the study. These horses came from entire age groups ranging from 5 to 11 years to maintain variance.
Findings
- The research found that Kazakh jabe type horses have a mean live weight of 433.5 kg, which significantly falls behind that of Novoaltay-Kazakh crosses with an average live weight of 515.3 kg.
- In terms of bodily measurements, the Novoaltay-Kazakh crossbreeds exhibited larger dimensions than Kazakh jabe type horses.
- The milk production of Novoaltay-Kazakh crossbred mares was found to be 1932 liters for the first 105 days of lactation, which was about 25.2% (487.2 liters) more than the milk productivity of Kazakh jabe type mares.
Chemical Composition of Milk
- Analysis of different genotypes’ mare milk composition established that the protein and fat content in Kazakh jabe mares’ milk was, on average, higher by 0.07% and 0.05% respectively, compared to Novoaltay-Kazakh crossbreeds.
Conclusion
- Finally, the live weight of mares in the experimental group was determined. The Novoaltay-Kazakh crossbreeds exhibited an average weight of 515.3 kg, or were roughly 15.8% (81.8 kg) heavier than the Kazakh jabe mares.
- The study concluded with the implication that the use of Novoaltay breed stallions could potentially enhance the milk productivity of native Kazakh horses of the jabe type, particularly under pasture and herd conditions.
