“…Karya sheep, characterized by high fertility and high milk production, are known to have originated from the non‐systematic introgressive crossbreeding of ewes belonging to sheep breeds local to the Aegean region, including, among others, the Dağlıç and Çine Çaparı, with rams of the breeds Sakız and Kıvırcık as well as Sakız X Kıvırcık hybrids (Karaca et al., 2018 ). Konya Merino sheep, characterized by high mutton and fleece production, on the other hand, are reported to have originated from the intra‐selection of the G2 and G3 hybrids of the German Mutton Merino and Central Anatolian Akkaraman (Sertkaya & Öztürk, 2022 ; Ünal & Akçapınar, 2001 ).…”

BackgroundReported as being expressed by mono‐ and binucleate placental cells, pregnancy‐associated glycoproteins (PAGs) are released into the blood circulation from the ruminant placenta. Circulating gestational PAGs levels may differ between sheep breeds.ObjectiveThis study was aimed at the close monitoring of the serum PAGs profiles of Karya and Konya Merino sheep during early pregnancy.MethodsFifteen Karya and 15 Konya Merino ewes were synchronized by a 12‐day treatment with progesterone‐impregnated intravaginal sponges. After the sponges were withdrawn, the ewes were administered 400 IU of equine chorionic gonadotropin. The ewes were allowed to mate naturally, and all animals were sampled for blood as of the day of mating (day 0) at weeks 1, 2, 3, 4 and 5. Pregnancy diagnoses were made by transabdominal ultrasonography at week 5. At weeks 6, 7, 8, 9 and 11, blood samples were collected only from the pregnant ewes. The blood samples were centrifuged at 3000 × g, and extracted sera were stored at −20°C until being used for laboratory analyses. Serum PAGs levels were determined with the aid of a commercial PAG‐enzyme‐linked immunosorbent assay test originally developed for pregnancy diagnosis in cattle. Differences in the between the PAGs levels throughout pregnancy and the group effect (Karya and Konya Merino) were determined with a two‐way mixed analysis of variance. Pairwise comparisons were made using a Bonferroni adjustment.ResultsPAGs levels showed a linear increase with the advance of pregnancy in both Karya and Konya Merino sheep. No difference was detected between the breeds for serum PAGs levels. The serum PAGs levels of the pregnant and non‐pregnant ewes differed as of the fourth week.ConclusionThe serum PAGs levels of the Karya and Konya Merino ewes were similar during the first 11 weeks of gestation, and pregnancy diagnosis could be made based on serum PAGs levels as of the 4th week in both breeds.

This research delves into the pre-weaning growth and fleece characteristics of the Central Anatolian Merino sheep breed, focusing on Türkiye's National Community-Based Small Ruminant Breeding Program. The study encompasses Central Anatolian Merino lambs born between 2016 and 2021 across 22 farms in Ankara province, amassing a dataset of around 35,344 observations. Economically important traits such as birth weight (BW), weaning weight (WW), average daily weight gain (ADWG), Kleiber ratio at weaning (KR), fiber diameter, and fiber length (measured in approximately 4,809 observations) were scrutinized. Rigorous statistical analyses, including outlier identification, normality assessment, and the development of linear mixed models, were employed to unravel the impact of environmental factors on these traits. Significant findings emerged, indicating that birth weight, weaning weight, and the Kleiber ratio were substantially influenced by variables such as sex, birth type, birth season, birth year, and flock size. Moreover, average daily weight gain exhibited noteworthy variations attributed to gender, birth type, birth season, birth year, flock size, and other environmental factors, underscoring their collective impact on growth. Fleece traits displayed considerable diversity influenced by gender, birth type, birth season, birth year, and flock size. This study sheds light on the intricate interplay between environmental factors and pre-weaning growth traits within the Central Anatolian Merino sheep breed. Beyond its scientific contributions, this research provides valuable insights aimed at bolstering productivity. The adaptability of the Central Anatolian Merino breed to arid climates and challenging pasture conditions positions it as a key player in Türkiye's broader agricultural development.
