Bu çalışma, Balochistan’daki Yetabad Koyun Araştırma Merkezi’nde yetiştirilen Balochi ve Bibrik (Beverigh) koyunlar ırklarının performanslarını değerlendirmek için yürütülmüştür. Kırkaltı baş koçun 490 koyun ile çiftleştirilmesiyle elde edilen 1171 baş kuzuya (630 baş Balochi (n=630) ve Beverigh (n=541)) ait kayıtlar 3 yıllık periyotta toplanmıştır. Özellikler olarak, erkek ve dişiler için doğum (BW), 120. (WW), 180. (6MW), 365. ve (12MW) günlerdeki ve 24. aydaki (24MW) canlı ağırlıkları değerlendirilmiştir. Elde edilen veriler standart varyans analiz metoduyla analiz edilmiştir. Balochi ve Beverigh ırkı erkek kuzular için doğum ağırlıkları sırasıyla 3.33±0.75 ve 2.99±0,45 kg, dişi kuzular için doğum ağırlıkları sırasıyla 2.77±0.50 ve 2.54±0.33 kg olarak hesaplanmıştır. Balochi ve Beverigh erkek kuzularında 120 günlük canlı ağırlık için genel ortalama 17.56±1.41 ve 16.24±1.24 kg, Balochi ve Beverigh dişi kuzularda bu özellik 15.02±0.72 ve 14.01±0.59 kg olarak belirlenmiştir. Balochi ve Beverigh ırkı kuzular için 180 günlük canlı ağırlığı erkeklerde sırasıyla 21.26±1.31 ve 20.25±1.49 kg, dişilerde ise 19.15±0.83 ve 16.99±1.16 kg olarak tespit edilmiştir. 365. günlük canlı ağırlığı, Balochi ve Beverigh erkeklerinde 30.65±1.92 ve 27.92±2.39 kg, dişilerde 27.42±1.04 ve 24.17±1.14 kg olarak gözlenmiştir. 24 aylık canlı ağırlık özelliği için Balochi ve Beverigh erkekleri sırasıyla 39.18±3.96 ve 35.80±2.41 kg, dişileri ise 34.35±1.87 ve 32.41±2.24 kg olarak belirtilmiştir. doğum (BW), 120.

Evaluation of Economic Traits of Balochi and Bibrik (Beverigh) Sheep Breeds of Balochistan, Pakistan

This study was conducted to evaluate the performance of Balochi and Bibrik (Beverigh) sheep breeds reared

under farm flock system at sheep research Centre Yetabad, Balochistan. Records on fourteen hundred and five (n=1171)

lambs (Balochi (n=630) and Beverigh (n=541)) descended from (n=490) ewes and (n=46) rams data were collected for

period of three years (2005 - 2007). Traits were evaluated for male and female lambs of weights at birth (BW), 120 days

Weaning weight (WW), 180 days (6MW), 365 days (12MW), 24 months (24MW), respectively. The collected data were

subjected to statistical analysis by standard methods of analysis of variance. The birth weight averages for Balochi and

Beverigh breeds were 3.33±0.75 and 2.99±045 kg for male and 2.77±50 and 2.54±0.33 kg for female lambs respectively.

The overall averages for WW male lambs of Balochi and Beverigh breeds were 17.56±1.41 and 16.24±1.24 kg and

15.02±0.72 and 14.01±0.59 kg for female lambs respectively. The live weight at 6MW was averaged 21.26±1.31 and

20.25±1.49 kg for male lambs, and for female lambs 19.15±0.83 and 16.99±1.16 kg of Balochi and Beverigh respectively.

The live weight averages at 12MW of Balochi and Beverigh lambs were found as 30.65±1.92 and 27.92±2.39 kg for male

lambs and 27.42±1.04 and 24.17±1.14 kg for female lambs, respectively. For Balochi and Beverigh breeds, the overall

average values for 24MW male lambs were 39.180±3.96 and 35.80±2.41 kg and 34.35±1.87 and 32.41±2.24 kg for 24

MW female lambs respectively. Statistically significant effects of breed, type of birth and sex on live weight at BW, WW,

6MW, 12MW and 24MW ages were found (P<0.05). However, 9MW was not affected by type of birth (P>0.05). All

reproductive traits were found non significant (P>0.05), whereas significant difference in twinning percentage between

two breeds was detected (P<0.05). Results reflected that Balochi and Beverigh breeds can be improved through better

selection and management.
