Симментальский скот немецкой селекции в условиях Хакасии

Симментальский скот немецкой селекции в условиях Хакасии

Abstract

The studies were conducted in order to identify opportunities for the use of German Sim-mental cattle improvement in the Republic of Khakassia. To do this, formed two groups of cows, heifers: control (local simmentals) and experienced (German simmentals). The article presents the results of research Exterior-constitutional features, morphological and functional properties of the udder and milk production of Simmental heifers German selection in Khakassia in comparison with local simmentalami. Found that the import selection of of fresh cows for 305 days of lactation re-ceived 4360 kg of milk with 3.90% fat content, protein 3.07%. According to the number obtained tion of milk they exceed domestic peers by 165 kg (3.9%), and the output of milk fat 13.8 kg (8.9%), milk protein 6.85 kg (5.4% ). The study of the exterior shows that animals are superior German selection of domestic fresh cows in all body measurements differ boned, well muscled. Live weight of imported of fresh cows 554.3 kg, 71.0 kg (14.7%) more than domestic. Thus, the use of German Simmental cattle breeding to improve the Simmental cattle in Khakassia advisable to increase the genetic potential for milk production, the fortress of the constitution, increased live weight, fat and protein in milk.

Исследования проводили с целью выявления возможности использования животных симментальской породы немецкой селекции для совершенствования крупного рогатого скота в республике Хакасия. Для этого были изучены две группы коров-первотелок: контрольная (местные симменталы) и опытная (немецкие симменталы). В сравнительном аспекте определяли экстерьерно-конституциональные особенности, морфофункциональные свойств вымени и молочную продуктивность животных указанных групп. От первотелок импортной селекции за 305дн. лактации получено 4360 кг молока с содержанием жира 3,90 %, белка - 3,07 %. По удою они превзошли местных сверстниц на 165 кг (3,9 %), по выходу молочного жира - на 13,8 кг(8,9 %), молочного белка - на 6,85 кг(5,4 %). Животные немецкой селекции превосходят местных коров-первотелок по всем промерам, отличаются крепким костяком, хорошо развитой мускулатурой. Живая масса импортных первотелок составила 554,3 кг, что на 71,0 кг (14,7 %) больше, чем у отечественных. Использование симментальского скота немецкой селекции целесообразно для совершенствования породы в Хакасии путем повышения генетического потенциала молочной продуктивности, крепости конституции, увеличения живой массы, содержания жира и белка в молоке.
