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.
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.
Photoperiod and shelter have direct or indirect effects on phenotypic traits expression in different fish species. The present study was, therefore, intended to explore whether these light and shelter could influence some phenotypic traits of African catfish larvae under laboratory condition. Newly hatched larvae were stocked in plastic aquaria (10L) at a rate of 5 individuals/L and reared for one month under four treatments such as 24h light (24L), 24 h dark (24D), 12h light and 12h dark with PVC (12DL_PVC), and 12h light and 12h dark without PVC (12DL) conditions. A total of 108 larvae were sampled for phenotypic traits analysis. The results revealed that complete darkness (24D) significantly improved the overall growth parameters (total length, standard length, caudal peduncle length, anal fin length, caudal fin length, total body depth, dorsal fin length, pre dorsal distance, pre anal distance, pre ventral distance, head width, head length, eye diameter, maxillary barbell length, inter orbital length, and specific growth rate) than all other treatments, while no significant variation was found among other treatments. Although shelter did not show any significant role in the overall growth, it significantly reduced the larval mortality than those reared without shelter. The survival rates were also significantly different among various light regimes in which the highest was found in 24D (86%) followed by 12DL_PVC (74%), 24L (71%), and 12DL (60%). The study also revealed that larvae reared in 24D exhibited maximum dark brown body colouration (63%), while in 24L showed maximum light brown colouration (96%). On the other hand, maximum larvae were appeared as medium brown color (76%) in tanks having PVC, whereas many of them were light brown (61%) in non-PVC tanks. Taken together, the study suggests that C. gariepinus larvae should be reared in completely dark condition to enhance their overall production.
The aim of this study was to give general information about the products status, breeding systems and to propose recommendation to improve the potentials about goat breeding in Turkey. For these purposes, FAO agricultural statistics is presented by evaluating data obtained. Turkey has significant potential in terms of small ruminant breeding, the number of animals and the production value. According to 2010 figures, 0.5% of the world goats' population is bred in Turkey with the presence of 5.1 million goats. As a result, over the years, based on the continuous decrease of goats in Turkey, there is a decrease of 9% of goats in comparison to the previous year. In 2010, there is a 30% increase in goat milk production and 9.2% decrease in goat and sheep meat comparing to the previous year.
Bu çalışmada, östrus senkronizasyonu uygulanan genç kilis keçilerinde (çebiç) iki farklı zamanda eCG (500 IU) uygulamasının östrus ve gebelik oranları ile yavru sayıları üzerindeki etkileri araştırılmıştır. Daha önce hiç çiftleşmemiş olan 13-15 aylık 23 çebiçe, üreme sezonu dışında 11 gün süre ile progesteron emdirilmiş süngerler (20 mg flugestone acetate) ve sünger uzaklaştırılmasından 2 gün önce PGF2α (125 mcg cloprostenol) uygulandı. eCG; 1. gruptaki çebiçlere (n:11, -48. saat grubu) sünger uzaklaştırılmasından 2 gün önce uygulanırken, 2. gruptaki çebiçlere (n:12, 0. saat grubu) sünger uzaklaştırma gününde uygulandı. Tekelerin atlamasına izin veren çebiçler östrusta kabul edildi ve çiftleştirildi. Her iki gruptaki tüm çebiçler östrus gösterdi. Birinci (-48. saat) grubun gebelik (oğlaklama) oranı (sırasıyla %54,6 ve %25.0, P>0.05) ve toplam yavru sayısı (sırasıyla 7 ve 3, P>0.05) ikinci (0. saat) gruptan sayısal olarak daha yüksek bulundu, ancak gruplar arasındaki farklılıklar istatistiksel olarak önemsiz bulundu. Çalışmada; gebelik oranı ve toplam yavru sayısındaki sayısal artışın ekonomik değerleri göz önüne alındığında, Kilis çebiçlerinde üreme mevsimi dışında eCG'nin sünger uzaklaştırılma zamanından ziyade, sünger çıkarılmasından 48 saat önce uygulanmasının daha faydalı olabileceği sonucuna varılmıştır. Effects of eCG application time on fertility in off-season estrus synchronized Kilis goat kids ABSTRACTIn the study, the effects of eCG (500 IU) administration at two different times on estrus and pregnancy rates and the number of offspring were investigated in estrus-synchronized goat kids. Twenty three kilis goat kids 13-15 months old that had never mated before were treated out of the breeding season with a progesterone sponge (20 mg flugestone acetate) for 11 days and PGF2α (125 mcg cloprostenol) two days before sponge removal. While eCG was applied to kids in group 1 (n:11, hour -48 group) two days before sponge removal, it was applied to kids in group 2 (n:12, hour 0 group) on the day of sponge removal. Goat kids that allowed the bucks to jump were considered estrus and mated. All kids in both groups showed estrus. The pregnancy (kidding) rate (54.6% vs. 25.0%, respectively, P>0.05) and total number of offspring (7 vs. 3, respectively, P>0.05) of the 1. (hour -48) group were found numerically higher than the 2. (hour 0) group, but the differences between the groups were not statistically significant. Considering the economic values of numerical increase in the pregnancy rate and the total number of offspring, it was concluded that it may be more beneficial to apply eCG 48 hours before the sponge removal rather than at the time of sponge withdrawal out of the breeding season in Kilis goat kids.
