Résumé :

Four selection strategies aimed at maximizing egg production in laying hens were compared with respect to expected annual genetic gain (G(A)). The selection strategies were: (1) (S1P) Traditional single-stage selection based on a single-house production system using partial records for both the individual and its ancestors, (2) Single-stage selection based on a single-house production system u ...

Résumé :

Fifteen generations of selection were conducted to study responses for litter size at birth (LSB), weight at weaning of standardized litter (LWW), and individual body weight at 8 wk of age (BW8) using golden hamsters as an experimental model for pigs. The experiment involved three lines: selection on an aggregate breeding value of LSB, LWW, and BW8 (line W); selection on an aggregate breeding ...

Résumé :

Research of the selection efficiency of boars of Belarusian meaty and Large White breeds for reproduction and productivity indices was realized in the selection and breeding centre Zadneprovski in the Republic of Belarus. The influence of 25-percentage level of boar selection for sperm production with the dominancy of relative average values of an initial population on statistically significan ...

Résumé :

C-reactive protein (CRP) may be a useful marker of health and animal welfare. The aim of this study is to measure plasmatic levels of CRP in two lines of rabbits divergently selected for environmental variability in litter size. Females of the high line (H) for environmental variability in litter size showed higher concentration of CRP at beginning of their reproductive life (D = 7.62 microg/m ...

Résumé :

A divergent selection experiment on phenotypic variance of litter size was carried out in rabbits. Selection was based on phenotypic variance of litter size for each doe after correcting litter size for the effects of year-season and lactation status (Ve). Selection pressure on does was approximately 30% in each line. Males were chosen within sire families in order to avoid the increase of inb ...

Résumé :

The choice of a marker-aided recurrent selection (MARS) strategy depends on a number of factors. An experimental comparison of these factors can be costly or infeasible, but a theoretical comparison can provide some guidelines. This study was conducted to evaluate the genetic aspects of expected responses to various MARS methods and to compare the efficiencies of MARS relative to traditional p ...
