Comparison of plasma testosterone, thyroid levels, and semen characteristics of local and cross of improved awassi strains in jordan

Bu çalışmada, Ürdün’de farklı yaşlardan İvesi koyunlarına ait farklı kökenlerin semen kalitesi ve plazma testosteron (T), tetra-iodothyronine (T4) ve tri-iodothyronine (T3) düzeyleri değerlendirilmiştir. Nisan başından itibaren Eylül sonuna kadar Ürdün’de Khanasry İstasyonu’nda bulunan 12 yerel İvesi koç (6’sı yetişkin ve 6’sı toklu) ve 7 çapraz ıslah çalışması yapılmış İvesi koçuna (4’ü yetişkin ve 3’ü toklu) ait fiziksel incelemeleri, sperm özellikleri ve kan örnekleri değerlendirildi. Yerel İvesi koçlarında, çapraz ıslah çalışmaları yapılan İvesi koçlarına oranla daha geniş (P

Ürdün’de yerel ve çapraz ıslah çalışmaları yapılan ivesi ırklarında plazma testosteron, tiroid düzeyleri ve semen özelliklerinin karşılaştırılması

This study conducted to evaluate semen quality and plasma testosterone (T), tetra-iodothyronine (T4), and tri-iodothyronine (T3) concentrations for different strains of Awassi sheep of different ages in Jordan. Physical traits, semen characteristics and blood samples were assessed in 12 local Awassi rams (6 matures and 6 yearlings) and the 7 crosses of improved Awassi rams (4 matures and 3 yearlings) from the beginning of April until the end of September at the Khanasry Station in Jordan. Local Awassi rams had greater (P
