The aim of this study was to uncover certain physical properties of cashmere fibres obtained from goat hair in Van, Turkey, and determine their usability in the textile sector. For this purpose 36 hair goats were studied, aged between two and three years old, obtained from breeders at Van Yüzüncü Yıl University Livestock Facilities and the Özalp and Başkale districts of Van, with twelve goats being taken from each breeder. The sample of hairs were collected by combing three areas of the goat's body (shoulder, flank and rump). The analysis indicated that the cashmere length of two-year-old hair goats was longer than that of three-year-old hair goats. There was no linear relationship between the differences among cashmere elasticity and yield properties and the altitude levels of the districts. It was determined that the fibre diameter of the cashmere of hair goats in Van was acceptable for the textile sector and competitive with major cashmere-producing countries.

This study aimed to determine the densities of fiber follicles in the skin of the Karakaş, Norduz, and Zom sheep breeds and to carry out a comparative analysis between them. The study included a total of 36 animals aged 1-2 years and 3-4 years. Skin samples were obtained through biopsies taken from the right sides of the animals to determine the densities and ratios of the fleece follicles. Examination of these samples revealed that the primary follicle densities of the three sheep breeds (Karakaş, Norduz and Zom) were 3.11 ± 0.42, 3.14 ± 0.49 and 3.34 ± 0.59, while the secondary follicle densities were 8.42 ± 1.48, 8.51 ± 1.54 and 6.36 ± 1.44. The secondary to primary (S/P) follicle ratios of the sheep were 2.71 ± 0.70, 2.79 ± 0.69 and 1.85 ± 0.36, respectively. The primary follicle densities of the Karakaş, Norduz and Zom sheep were statistically similar for both age groups. The density of secondary follicles and S/P ratio decreased with age in both age groups. The similarity of the S/P ratios to those from other local sheep breeds suggest that Karakaş, Norduz, Zom sheep can be included in the sheep group that has coarse fleece.

Öz: Bu çalışmanın amacı, Ile de France X Akkaraman ve Ile de France X Anadolu Merinosu melezlerinde bazı yapağı karakterlerini araştırmaktır. Çalışmanın hayvan materyalini, 50'şer baş Akkaraman ile Anadolu Merinosu ve 61 baş Ile de France X Akkaraman melezi ve 75 baş Ile de France X Anadolu Merinosu melezi oluşturmuştur. Araştırma sonuçlarına göre; Akkaraman, Anadolu Merinosu, Ile de France X Akkaraman (G1) ve Ile de France X Anadolu Merinosu (G1) koyunlarında sırasıyla; yapağı verimi (kg) 2.36, 3.57, 3.14 ve 3.15; incelik (µ) 30.99, 25.16, 28.81 ve 25.47; lüle uzunluğu (cm) 9.50, 6.85, 8.17 ve 7.55; gerçek uzunluk (cm), 19.34, 13.12, 16.34 ve 14.66; randıman ise (%) 69.72, 59.13, 63.84 ve 63.58 olarak saptanmıştır. Bu çalışmada melezlemenin; Akkaramanlarda yapağı verim artışı ve yapağı inceliğini, Anadolu Merinoslarında ise lüle uzunluğu ve gerçek uzunluk değerlerini arttırarak yapağı kalitesinde iyileştirmeler sağladığı gözlenmiştir.

An investigation of the lead and cadmium levels of blood serum and wool of White Karaman sheep in the Van region (Turkey) -1381 -

The aim of this study was to compare the reproductive traits, lactation milk yield, and body measurements of the Damascus (Shami) and Kilis goats raised as dairy goats in the dry climatic conditions of the Southeastern Anatolia region of Turkey. The study was perfomed using 596 Damascus goats and 82 Kilis goats between 3-5 years old. It was observed that the lactation milk yield, lactation period, withers height, and leg circumference of the Damascus goats (175.86 kg, 227.48 days, 72.67 cm, and 74.10 cm, respectively) were significantly higher (P<0.05) than those of the Kilis goats (107.48 kg, 170.39 days, 69.70 cm and 71.83 cm, respectively). This analysis indicated that the Damascus goat may be a good breed for dry climatic conditions. It is suggested that focusing on growing Damascus goats could increase productivity in the Southeastern Anatolian region of Turkey.

This study was conducted to compare Central Anatolian Merino (CAM) and Malya sheep under intensive conditions in terms of reproductive traits, birth and weaning weights, fattening performance, and some fleece characteristics. In this study, 840 CAM and 194 Malya ewes were used for the comparison of reproductive performance, whereas 740 and 211 lambs were used to compare growth traits between the two breeds. Additionally, the fattening performance of 61 CAM and 68 Malya lambs were compared. Finally, for the comparison of wool quality traits, 94 CAM and 90 Malya lambs were used. The lambs were kept together with the sheep that gave birth to them for 10 days. After this period, lambs were given lamb starter feed, alfalfa hay, and vetch hay in addition to milk. When lambs reached 40 days old, they were taken to the pasture with the sheep. In this period, pasture grass, growing lamb concentrate feed, alfalfa hay, and vetch hay were given in addition to milk. Lambs were weaned when they reached an average age of 90 days, and their live weights were determined. A determined number of lambs was selected from weaned male lambs. For these animals, in the fattening period, barley, alfalfa hay, vetch hay, meadow hay, and lentil straw were provided ad libitum in addition to 400 g/day/head of fattening feed. This study indicated that birth rate was better for CAM sheep than for Malya sheep. However, Malya lambs may have more advantages than CAM lambs in terms of survival and fattening performance. Although birth weight was higher for Malya sheep than for CAM sheep, the opposite result was observed for the weaning weight. The beginning weights of fattened male lambs were higher for CAM lambs than for Malya lambs, but the ending weights of both fattened groups were similar.
