Abstract:

The data pertaining to 623 purebred and 202 Fec-B gene introgressed Kashmir Merino lambs born to 25 and 11 sires, respectively were analyzed with the Mixed Model Least Squares and Maximum Likelihood algorithms, PC-2 version computer programme (Harvey. 1990) to assess the effect of Fec-B gene introgression and some non-genetic factors on performance traits of Kashmir Merino sheep. The overall least-squares means for birth weight (BW), weaning weight (WW), six months body weight (W6), yearling body weight (W12), adult body weight (W18), Average greasy fleece weight (AGW), fibre diameter (FD), staple length (SL), Crimps/ cm (CPC), Medullation (ML) and litter size (LS) were 3.27±0.03 (Kg), 11.38±0.16 (Kg), 16.30±0.45 (Kg), 19.54±0.23 (Kg), 24.23±0.27(Kg), 32.43±0.41 (Kg), 1.75±0.03 (Kg), 20.99±0.10 (µ), 3.43±0.10(cm), 4.84±0.0.20 (No/cm) 3.26±0.37 (%) and 1.20±0.22, respectively. Purebred Kashmir Merino performed better than Fec-B transgressed. However, the difference was significant for BW, AGW, CWY, FD and ML. The effect of year of birth was significant on all traits except W18. However, the effect of age of dam was non-significant on all traits. The effect of sex was significant on BW, W12, FD and CPC. The birth weight and wool traits were significantly affected by Fec-B introgression.
