Abstract
The aim of this study was to morphologically characterize the Sohagi sheep and identifying some productive traits such as birth weight (BW), weaning weight (WW90) and year of age (W360) and some genetic parameter estimates as a new breed ready to add to the animal genetic resource in Egypt, The results presented in this work were collected from the data recorded in the farm of the Faculty of Agriculture of following up the performance of Sohagi sheep herd kept in closed population through a period of 22 years, The traits recorded are body weights at birth weight (BW); weaning weight (WW90) and one year age 360 days. The data included 1290 lambs records originated from 44 sires and 490 dams. The records of BW, WW90 and W360 were analyzed. The results showed that these group have a unique and homogenize morphological performance which successfully allow to suggest that these group of animals could be identified as a new breed that given the name Sohagi sheep. This group characterized also by the following: birth weight (BW) is 2.96 ±0.03kg, weaning weight(W90) is 14.61 ±0.16 kg and one year age (W360) is 30.20 ±0.33 kg in females. While in male, birth weight (BW) is 3.03 ±0.03 kg, weaning weight (W90) is 15.65 ±0.17 kg and one year age (W360) is 36.32 ±0.36 kg. Daily growth rate in males from birth to weaning was 138.63 ± 1.15 gm, from weaning to 6 months 62.83 ±0.98 gm, from 6 to 9 months 71.49 ± 1.21gm and from 9 to 12 months 90.24 ± 1.41gm. Daily growth rate in females from birth to weaning was 128.37±1.10gm, from weaning to 6 months 53.02 ± 0.79gm, from 6 to 9 months 53.54 ± 0.99gm and from 9 to 12 months 60.70 ±0.80gm. The estimate of heritability of birth weight, weaning weight and weight of one year age were 0.09± 0.045, 0.56± 0.061 and 0.29± 0.055, respectively. Parallel to this work, a group of molecular characterization studies were implemented which confirmed that Sohagi is an independent breed.
