DYNAMICS OF WEIGHT AND LINEAR GROWTH OF HEIFERS OF UKRAINIAN RED AND WHITE AND UKRAINIAN BLACK AND WHITE DAIRY BREEDS
The results of researches of dynamics of weight and linear growth of heifers of Ukrainian red and white and Ukrainian black and white dairy breeds are given in the work. It is necessary to lay the foundations for high productivity of adult animals with optimal health during the rearing period of cattle, which is associated with the growth and development of the young organism. The live weight of an animal at a certain age and its exterior are indicators of the quality of rearing. Increasing the impact of proper breeding on productive animal quality can be achieved through targeted and effective selection.
Diets for heifers at different ages were generally balanced on nutrient content. So, in the winter period in average diets for heifers aged 6-12 months, the energy concentration in 1 kg of dry matter was 0.8 feed. units and 0.74 kg at 12-18 months of age, and 0.9 and 0.91 feed units respectively in the summer.
Thus, the feeding of experimental heifers during the period of research almost completely corresponded to scientifically-based standards for obtaining average daily weight gain of 600-700 g.
The criterion for differences between calves' live weight from birth to 18 months of age ranges from 3.1 to 4.63 in favor of animals of Ukrainian red and white milk breed.
The growth rates of heifers of various breeds were different. The average daily weight gain of heifers of the Ukrainian red and white milk breed in the first half of life was 730, in the second - 760; in the third - 450 g. per head. The growth rate of heifers of the Ukrainian black-and-white dairy breed was 703, 737, and 471, respectively.
The dynamics of weight and linear growth of heifers depending on age and breed were studied in parallel. We also studied the correlation between live weight and individual calf body measurements. As a result of these studies, a positive correlation was found between live weight and chest girth at the shoulder blades and oblique calf length. Therefore, the basic measurements of the calf's body are interrelated with their live weight regardless of breed.
