the data of this study were collected by indigenous chicken breeding centers in the west azerbaijan for 11 generations. the (co) variance components, heritability's, correlations between traits and breeding values were estimated by multi-trait animal model using wombat software. the genetic trends of traits over 11 generations of selection, using average function of breeding values per gen...

pathological changes within an organ can be reflected as proteomic patterns in biological fluids such as plasma, serum, and urine. the surface-enhanced laser desorption and ionization time-of-flight mass spectrometry (seldi-tof ms) has been used to generate proteomic profiles from biological fluids. mass spectrometry yields redundant noisy data that the most data points are irrelevant features ...

This study was carried out to investigate the direct and indirect responses to selection for four-week body weight (4 week body (wk BW)) and four-week breast weight (4 week breast weight (wk BRW)) and to determine the genetic contribution of reminder founders to the last generation. A total number of 351 birds were equally allocated to three lines, including two selected lines (S1 and S2 for BW...

the aim of this study was to design the base breeding plan in sistani cattle by using of stochastic simulation. for this purpose, three population size (500, 1000, 2000 heads), three levels of herd number (5, 10, 20), two levels of selection intensity (high and low) and two levels of mating method (random and minimum co-ancestry) were combined together and in total 36 scenarios were compared fo...

this study was evaluated some strategies and determined the suitable selection index for afshari sheep using simulated data. the relative importance of traits was determined based on the estimated economic values and consequently, the most benefit traits were applied to selection indexes construction. the interest indexes were different combination of traits including ewe body weight (ebw), ann...

Use laboratory animal for research purposes is often used especially in the fields of health research, food, agriculture, and livestock. The that as objects include rabbits, mice, guinea pigs, monkeys, rats. Research field livestock breeding requires a long time to large number animals so mice can be apply it. goal determine effect selection program on parameters body weight including weaning a...
