Improving the competitiveness of fine-wool sheep using local and world stud rams

Abstract

The article compares merino sheep imported from Australian plants in 2004 and 2007 compared and domestic merinos of leading breeding plants of Russia and Stavropol. Australian merinos imported in 2004 did not have a positive effect when crossed with Manich merino ewes. At the same time, the 2007 importation of Australian rams by differentiated selection of Manich merinos depending on their live weight and age, increased meat productivity of their offspring but reduced the level and nature of their wool productivity and comprehensive assessment of animals. In the herds of the Stavropol and Caucasian breeds, the best results were obtained when using stud rams of domestic breeding plants
