The growth and development of young animals and the efficiency of crossing ewes the Ascanian Fine-Fleeced breed (AFF) with ram-sires of Texel (AFFxT) and Merinolandschaf (AFFxM) were studied. It was found that hybrid lambs AFF × T have a significantly higher live weight at birth – 5.8 kg against 4.7 kg in purebred peers. The revealed difference for these lambs remained in the following ontogenesis periods. In general, from birth to 6 months of age, the average daily gain increase in ram-lambs AFF × T was higher compared to purebreds and crossbreeds AFF × M by 16.6 and 6.4%, respectively. When estimating the growth rate of livestock during the rearing period, it was shown that AFFxT youngling  probably prevailed in the average daily gains of AFF analogues by 26.1 g, and AFFxM by 9.6 g. over lambs the other two groups on such parameters, as height in buttocks, breast width, breast depth, oblique length of a trunk, a breast girth,  which are completely confirmed by body structure indices. In particular, at birth and at the age of two, four and six months, these youngling had higher thoracic and massiveness indices. The uniformity index showed that these crossbreeds grew more evenly and had the highest value of this indicator, compared with animals of other experimental groups. In contrast to purebred Merino peers in the early postembryonic period, they are characterized by significantly higher parameters of live weight gain, growth intensity, growth stress, as well as the young mutton meat qualities better characteristics. In contrast to purebred Merino peers in the early postembryonic period, they are characterized by significantly higher parameters of live weight gain, growth intensity, growth stress, as well as the young mutton meat qualities better characteristics.  In general, it was found that crossbreeding had a positive effect on the young animals’ meat parameters in the early post-embryonic period. The ram-lambs obtained from crossing Ascanian Fine-Fleeced ewes with Texel and Merinolandschaf are characterized by a high rate of growth and development, a better level of live weight gain compared to purebred peers. Nevertheless, the most effective combination is observed with the Texel breed, so it is advisable to use these ram-sires to increase the young animals live weight of sheep new created genotype and getting   the youngling with better quality mutton.

Key words: sheep, genotype, live weight, linear parameters, growth rate.

Анотація
Досліджено зв’язок рівня гетерозиготності за окремими білковими локусами із загальною кількістю виявлених антигенних факторів особин. Виявлено залежність продуктивних ознак овець від загальної кількості виявлених антигенів, що дозволить значно підвищити ефективність селекційно-племінної роботи у вівчарстві.
