This study was carried out to determine the effect of environmental factors on some yield traits in Kilis goats. For this purpose, 6000 heads of Kilis goats each year, and a total of 30000 goats and kids born from them for 5 years, were the subject of the research. Milk control in goats was calculated by the ICAR-AT method. At the end of the study, Average birth weight was 3.56 kg, weaning weight was 15.06 kg and daily live weight gain was 191.64 g in kids. KR value found to be 23.6±0.03 in kids. Lactation milk yield in mothers was determined as 367.64 kg. As a result, it was determined that environmental factors were effective on the reproductive parameters and milk yield characteristics of Kilis goats and the developmental characteristics of kids. The crucial determination of these factors in the breeding of this breed will increase the accuracy of selection. In addition, the success will also be increased by starting the transition from the traditional breeding approach to the genomic breeding method and by combining these two strategies.
The goal of this research was to investigate the wool properties of Malya sheep raised in Central Anatolia of Turkiye. In the investigation, a total of 90 head wool samples were collected, including 30 heads from the same herd’s adults (2.5 years and older), yearlings (1–1,5 years), and lambs (4–6 months). Fleece samples were collected from the shoulder, rib and rump areas of animals of all age groups. In these examples, the properties of length, fineness, elasticity and tenacity were determined. At the end of the study, the average greasy fleece weight was 2.2 ± 0.09 kg, the diameter was 25.7 ± 0.35 µ in lambs, 25.3 ± 0.27 µ in yearling, 26.7 ± 0.26 µ in adults; the average fleece length was 38.8 ± 1.05 mm in lambs, 70.1 ± 1.46 mm in yearlings, 62.3 ± 1.29 mm in adults. As a result, it was determined that the fleece of Malya sheep almost had the desired quality and characteristics in the textile industry. Therefore, scientific studies should be conducted to improve the properties of fleece. It would be appropriate to take permanent steps in cooperation with Public Institutions and Civil Society Organizations to produce, collect and process wool.

This study was conducted to investigate the effects of certain environmental factors on reproductive and milk traits in ewes, as well as growth performance in lambs, under semi-intensive management of Awassi sheep. The dataset comprised records from a total of 31.372 lambs born to Awassi ewes participating in the National Small Ruminant Breeding Program. Key parameters, including reproductive and milk yield traits in ewes and birth weight (BW), weaning weight (WW), average daily gain (ADG), and Kleiber Ratio (KR) in lambs, were analysed concerning dam age, lamb sex, birth type, and birth month. Statistical analyses were performed using the SPSS software package. At the end of the study, the mean values for BW, WW, ADG, and KR were found to be 4.29 ± 0.01 kg, 19.33 ± 0.01 kg, 250.73 ± 0.08 g, and 27.19 ± 0.01, respectively. The average 210-day milk yield and daily milk production in ewes were calculated as 219.15 ± 0.39 l and 1.22 ± 0.01 l, respectively. The findings demonstrate that environmental factors have significant impacts on reproductive performance and milk yield in Awassi sheep, as well as growth traits in lambs. A comprehensive evaluation of these environmental influences is essential for optimizing production efficiency, enhancing the effectiveness of selection programs, and playing a crucial role in sustainable productivity and resource utilization.
