Sheep farming plays an important role in the production of meat. Romanov breed is known for its high fertility and therefore is used all over the world due to increased production of lambs and lamb meat. Meat products are the main food elements of the man. Most of the inhabitants of industrialized countries cannot imagine their menu without meat. Value of meat for human health is known, it supplies protein to the body. The Yaroslavl Region is a leading region of the Romanov sheep breed. Therefore, the aim of our research was to determine the strength and reliability of the influence of the factor 'genetic value of the father' on productive characteristics of animals as a factor that helps to increase the productivity of animals. Upon determining the strength of the influence of factors for statistical data have used the procedure of generalized linear models (General Linear Models - GLM), and evaluation components of phenotypic variation attributes were analyzed by multivariate dispers...ive analysis. Our research has allowed allocating rams with genetic value that has the improving effect. Using the recommended lines the farmers of the Yaroslavl region may increase productive characteristics of animals and the profit of the farms and improve the efficiency of breeding.
Ovčarstvo igra važnu ulogu u proizvodnji mesa. Romanovska rasa je poznata po visokoj fertilnosti i zato se koristi svuda u svetu radi povećane produkcije jagnjadi i jagnjećeg mesa.Mesni proizvodi su glavni elementi hrane za čoveka. Većina stanovnika u industrijskim zemljama ne mogu da zamisle svoj meni bez mesa. Značaj mesa za ljudsko zdravlje je pre svega u tome što snabdeva organizam proteinima. Jaroslavski Region je vodeći region u gajenju romanovskih ovaca. Dakle, cilj našeg istraživanja bio je da se utvrdi snaga i pouzdanost uticaja ' genetske vrednosti oca ' na produktivne osobine životinja kao faktora koji pomaže da se poveća produktivnost životinja. Za utvrđivanje jačine uticaja faktora primenjena je statistička obrada podataka. Tom prilikom je korišćen postupak generalnog linearnog modela (Opšti Linearni modeli - GLM). Za evaluaciju komponenti fenotipske varijabilnosti atributa upotrebljene su multivarijacione disperzivne analize. Naše istraživanje je omogućilo identifikaciju ...genetske vrednosti ovnova sa koji imaju poboljšavajući efekat u potomstvu. Naša saznanja mogu pored naučnog doprinosa biti i od praktične koristi. Upotrebom preporučenih linija odgajivači ovaca u Jaroslavskom regionu mogu unaprediti proizvodne karakteristike životinja, poboljšati efikasnost odgajivanja i povećati dobit od farmi. Ovaj metod se može primeniti i na drugim populacijama ovaca.
