چکیده
Rabbit farming is a powerful source of dietary meat, rabbit fluff, and skins. The research was conducted at the farm Precarpathian State Agricultural Research Station Institute Agriculture Carpathian Region National Academy Agrarian Sciences. article describes creation new highly productive genetic populations rabbits identified as best options for crossing maternal paternal forms. Three breeds their hybrids were used industrial crossbreeding, which are maximally suitable conditions intensive production meat: breed Poltava silver, Soviet chinchilla, New Zealand white rabbit. After result found that combination crossbred females with purebred males chinchilla has positive effect on reproductive qualities female rabbits. Due to combinatorial heredity compliance keeping in Cherkasy Station, combinations rabbits, such 1/2 silver x rabbit, prevails control group (rabbit silver) by multiple fertility 9.2 %, high 5.1 milk probably 8.5 % number weaned 14.0 (P < 0.05), weight nest 28 days age 41.2 0.01; P 0.001). local young third fourth groups (1/4 1/4 2/4 3/4 rabbit) prevailed 0.001; 0.01)) analogs first indicator live weights accordingly 107 83 grams, highest intensity development up 0.001) had hybrid origin (609 ± 28.26 g), more 116 gram. By 90 age, second chinchilla) 0.05) over 117 – 156, 80 fifth 207 grams. Better tendency lifetime fattening, constitutional indicators origin:

1 Fundamental Aspects of Crossbreeding of Sheep : Use of Breed Diversity to Improve Efficiency of Meat Production
Breed diversity is a valuable resource of the sheep industry. Crossbreeding systems use breed diversity to increase productivity relative to purebred flocks. Crossbreeding systems vary in managerial complexity and in use of beneficial effects due to crossbred ewes and lambs. Efficiency of meat production is maximized in terminal crossbreeding systems by use of specialized sire breeds to complem...
