This study was carried out to determine the morphometric characteristics of the glandula lacrimalis in Siirt-colored Mohair goats and Romanov sheep using computed tomography (CT) images and to analyze the differences between sexes and species. CT images of the glandula lacrimalis of ten male and ten female Siirt-colored Mohair goats and ten male and ten female Romanov sheep were used in the study. Morphometric measurements were taken from transversal, sagittal and dorsal sections of the right and left glandula lacrimalis in both male and female animals. Morphometric values were statistically analyzed. As a result of the study, there was no sex-related difference in morphometric measurement parameters in the Romanov sheep breed. In Siirt-colored mohair goats, statistical differences were observed in terms of TY and DU values depending on sex. Statistical similarities and differences were determined between the two species in terms of morphometric parameters. In conclusion, statistical differences in the measurement parameters of glandula lacrimalis of adult Siirt-colored Mohair goats and Romanov sheep between sexes and species were determined using computed tomography images.

This study aimed to determine the fertility and growth traits, viability, and body measurements of the Romanov sheep under breeder conditions in the humid region of Turkey. The animal material of the research consisted of sheep imported from Ukraine in 2019. In the study, there are two farms with 31 and 44 ewes in the first year and three farms with 45, 34, and 32 ewes in the second year. The reproductive performances of 186 sheep and lambs in three different farms were examined, and nine rams, one ram per 20 sheep, were used for mating. Two‐year (2020 and 2021) data on the reproductive performance of pure Romanov ewes, survivability in ewes and lambs, and development characteristics in lambs were used in the present study. The conceived rate (88.17%), fecundity at birth (1.42) and at weaning (1.29), litter size at birth (1.76) and weaning (1.56), single (50.98%), twin (41.83%), and triplet birth rate (6.54%), and abortion rate (6.71%) were determined for 2 years average. Birth and weaning weights of lambs were affected by sex and birth type (p < 0.01). The Romanov sheep and their lambs did not satisfy the breeder regarding reproductive performance and lamb development.

Sunulan çalışmada üreme mevsiminde bulunan Romanov koyunlarında senkronizasyon protokolüne başlandığı gün D vitamini enjeksiyonunun kuzulama performansı ve bazı fertilite parametreleri üzerine etkisinin araştırılması amaçlandı. Senkronizasyon protokolüne başlandığı gün ilk gruptaki koyunlara kontrol grubundan farklı olarak D vitamini enjeksiyonu (1 mL, Provet-D3®, Provet, TÜRKİYE) yapıldı. Tüm koyunların kızgınlık senkronizasyonları, 14 gün süreyle 20 mg flugestone asetat içeren vagina içi sünger (Chronogest®, FRANSA) ve süngerin çıkarılma anında 300 IU kas içi eCG (Chrono-Gest/PMSG®, ALMANYA) enjeksiyonu ile yapıldı. Her iki grupta östrus (%100) gebelik (%100) ve kuzulama oranı (%100) benzerdi. Çoğul kuzulama oranının D vitamini uygulanan grupta daha yüksek olduğu saptandı. Fekundite ve verimlilik oranı da D vitamini uygulanan grupta daha yüksekti. Sonuç olarak D vitamini uygulamasının senkronizasyon protokolünden elde edilecek yavru veriminin artmasına katkı sağlayabileceği düşünülmektedir. D vitamini enjeksiyonlarının fertilite parametreleri üzerindeki etkilerini daha net ortaya koyabilmek için daha kapsamlı çalışmaların yapılması gerektiği sonucuna varılmıştır.
