Rezumat

The aim of the work was to study the influence of the technology of cultivation of lamb in the period of absence from mothers (in 90 days) to their development until 10 months of age and reproductive ability in early grown with a stallcamp (SLС) and pasture-camp (PLС) sheep keeping system in the conditions of "SEEF" Gontarovka " Institute of Animal Science NAAS. It has been established that already at 180-day age, the bright in the PLC group was superior to a 9.0% peers (p <0.05), and the differences increased to 19.4% and 21.2 by the 270-330-day age % (in both cases p <0.001). Upon completion of the experience, the body mass was 43.8 ± 0.98 kg and 53.1 ± 0.68 kg, respectively. Considering the fact that the bright of the second group at the end of the experience was exceeded by 20.7% for development on the indicators of the standard for animal class of the elite established for the one-year-old age, their insemination was conducted within 35 calendar days. In the current year their bonus was carried out and evaluating the results of the jum. It has been established that bright, for the period of suddenness, they increased a body mass to 59.5 ± 1.16 kg (by 12.1%), and their unearthly peers - up to 63.3 ± 0.87 kg (by 19.2%). Nastrig unwashed wool in compared groups amounted to 5.47 ± 0.17 and 5.74 ± 0.16 kg (differences in 4.9%), and the length of the wool - 14.4 ± 0.41 and 13.9 ± 0.32 cm (differences 4.0%). Fertilization amounted to 53.6%. The best gender early maturity was different daughters of the producers of the generated lines based on the introductory crossing with the Romanovskaya breed , and the breed of Merinolandshaf. Overall, revenue from the sale of products from the injuries grown using PLC and subsequent insemination at the age of 10-11 months. It was 11.8% more against the not a lambing peers.
