Abstract :

The effect of natural selection on the natal period was studied on rabbits of six breeds and minks of two color forms. The graphic method was used in the research. The dashed line designated fertility curves, and continuous one -the distribution of the newborns. The percent of stillboras against total number of the newborns was represented on the diagram as arrows. In rabbits of all breeds, a ...

Abstract :

The monograph deals with breeding of dairy breeds of sheep. In the monograph are reported results of a number of experiments aimed at creation of sheep populations with better milk efficiency, good milkability and state of health in udder. There were used modern methods of estimation of genetic parameters and breeding values in sheep, progressive methods to determine important functional and m ...

Abstract :

The success of selection-breeding programs appreciably depends on accuracy of definition of breeding value of animals. Traditional methods of estimation the animals based on phenotypical parameters of parents and descendants, at the present stage cannot satisfy to the full the requirements shown to selection. Parameters of economic-useful attributes influence both paratypic, and genotypical fa ...

Abstract :

It is established, that thoroughbred boars of the Belarus meat breed differ a high parameters level of an estimation on own efficiency and surpass in all cases similar parameters of mixed contempoparies, young pigs concede on age of achievement of 100 kg alive weight for 8,3 day and to a daily average gain - on 20g. Boars, intended for reproduction, surpassed average indices of all contempopar ...

Abstract :

The basic parent breed of pigs in Belarus is Large White breed. It makes about 90% in structure of breeding animals, and up to 70% of commodity young growth received with its participation. Influence of this breed on pig-breeding branch has determining value. In commodity cultivation of pigs it is used as the parent form, both in pure line, and in various variants of crossing and hybridization ...

Abstract :

Responses to selection for number of piglets born alive (NBA) by the total number of piglets born (TNB), the NBA, and the NBA plus number of piglets born dead (NBD) were compared using the accuracy of selection and expected genetic gain calculated from the selection index with family information and the real response to selection, using data generated by Monte Carlo computer simulation. The ac ...

Abstract :

Complex selection indexes combining partial breeding values for milk performance, fertility and body conformation are proposed for bulls of Holstein cattle in the Czech Republic. Conformation is expressed either by linear classification or by general characteristics and body measurements. Different variants of selection indexes were tested. The breeding objective included either all or only so ...
