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 :

In order to congregate the desirable genes in local onion population of Gholy- Ghesseh, mass selection method was used in this study carried out from 1998-2002 in Kheir-Abad Agricultural Research Center, Zanjan, Iran. In 1998, based on bulb characters , single bulbs were selected and in the next year , planting was conducted in isolated plots providing open pollination. Seeds of selected plant ...

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 :

La supervivencia de las razas ovinas autóctonas españolas ligadas a su área de difusión natural tras la implantación de la nueva reforma de la Política Agraria Común (PAC) pasará obligatoriamente por el incremento de la eficiencia productiva y reproductiva de los rebaños, haciéndose necesaria, entre otras tecnologías, la puesta en marcha y desarrollo de esquemas de selección modernos que incre ...
