“…Hierarchical clustering analysis used with the nearest neighbour method with Euclidean distance executed only selected effective variables in the present study. As expected, the Bafra and Karayaka breeds were grouped in the same cluster due to their higher similarity ratio (98.7%), Bbecause the Bafra breed is a crossbreed of Karayaka with Chios sheep breeds [2,6]. Similarly, the Akkaraman and Malya breeds had a higher similarity ratio (97.5%) and were grouped in the same cluster.…”

“…Small ruminants have been important components of rural life and still play a substantial role in the livelihood of farmers [1]. In Turkey, sheep production plays an important role in the livestock sector because of the country's geography and climate, as well as social, cultural, and economic structures [2]. As in many sheep-producing countries, sheep are generally reared for lamb meat production.…”

“…There are more than 42 million sheep in Turkey, which are mainly fat-tailed breeds, and also a small percentage of crossbreeds with foreign genotypes [3]. Akkaraman, Morkaraman, Karayaka, Awassi, Malya, and Bafra sheep, covering almost 80% of native sheep breeds in Turkey [3], are largely suited to a variety of harsh geographic and environmental conditions [2,[4][5][6]. Lambs of these breeds are an important source for the red meat sector under harsh climate conditions [4][5][6].…”

The aim of this study was to classify placental characteristics of Akkaraman, Morkaraman, Karayaka, Awassi, Malya, and Bafra sheep breeds using the hierarchical clustering method. In total, 240 individual data records were used as experimental material. Placental characteristics such as total cotyledon surface area, small and large cotyledon length, small cotyledon depth, etc. were used as explanatory variables to classify the breeds’ characteristics. Hierarchical clustering was used with the nearest neighbour method with Euclidean distance in order to classify the sheep breeds’ variations. As a result, six breeds were separated into three clusters: the first cluster consisted of Bafra, Karayaka, and Awassi breeds; the second consisted of Akkaraman and Malya breeds; and the third cluster included only the Morkaraman breed. Bafra and Karayaka were pointed as the nearest breeds, with a similarity of 98.7% in terms of placental characteristics. The similarity rate of the Akkaraman and Malya breeds was at a level of 97.5%, whereas it was 96.8% for Bafra, Karayaka, and Awassi breeds. The similarity of Akkaraman, Karayaka, Awassi, Malya, and Bafra sheep breeds was estimated as 95.7%. The overall similarity was found to be at a level of 93.2% among sheep breeds. The outcomes of the study might be useful as a selection tool for reproductivity and can be used to select the breed to be reared.

“…On the other hand, Bafra sheep were obtained from Chios breed which stands out with its meat quality besides the high milk and fertility and also Karayaka breed which has adapted to the Black Sea conditions in Türkiye [8]. The lactation milk yield of Bafra ewes has been reported as 111-150 kg and the lactation period as 120 days [9].…”

This study was carried in order to evaluate the linear morphological characteristics of the udder and teats in the breeder conditions of Awassi and Bafra (Chios × Karayaka) ewes (Ovis aries) and to determine the udder types, lactation milk yield and the lactation period of the ewes. One hundred two Awassi and 61 Bafra ewes were included in the study. The means of the linear scores of udder depth, udder furrow, udder attachment, teat shape, teat angle and teat placement in Awassi ewes were determined as 6.10 ± 0.27, 6.33 ± 0.27, 4.49 ± 0.27, 6.49 ± 0.33, 3.98 ± 0.29, and 1.47 ± 0.14, respectively. The same parameters were determined as 6.31 ± 0.28, 6.77 ± 0.32, 5.72 ± 0.24, 1.20 ± 0.11, 1.72 ± 0.26, and 1.20 ± 0.11, respectively, in Bafra ewes. Significant differences were found between Awassi and Bafra breeds in terms of udder types (P<0.01). The type 3 udder, suitable for milking, was determined at the highest rate in both breeds, but type 2 udder was not detected in Awassi ewes. Statistically significant differences were found between Awassi and Bafra ewes in terms of linear morphological characteristics of udder and teat, udder attachment, teat shape, teat angle and 60th day milk yield, daily average milk yield and lactation period (P<0.01). Lactation milk yield and lactation period were calculated as 139.85 ± 5.31 kg and 208.53 ± 4.471 days, respectively, in Awassi ewes and 145.91 ± 9.97 kg and 175.23 ± 4.635 days in Bafra ewes, respectively. As a result, in order for linear udder characteristics to be used safely as an indirect selection criterion, there is a need for studies with a higher number of ewes and to calculate the repeatability and heritability.

“…Akkaraman sheep are bred across a wide geographical area that includes Central Anatolia and nearby provinces (Boztepe, 2015;Kaymakçı, 2016). Many researchers have reported the following results for Akkaraman sheep: live weight is 35-50 kg (Boztepe, 2015), milk yield is 40-99.57 kg (Esen and Özbey, 2002;Mundan and Özbeyaz, 2004;Özmen et al, 2015;Kaymakçı, 2016;Kahraman and Özkul, 2020), lactation length is 120-155.80 days (Kaymakçı et al, 2001;Esen and Özbey, 2002;Mundan and Özbeyaz, 2004;Sönmez et al, 2009;Özmen et al, 2015;Kahraman and Özkul, 2020), twinning rate is 4.00-20.80% (Akçapınar et al, 2000;Kaymakçı et al, 2001;Esen and Özbey, 2002;Özmen et al, 2015;Ceyhan et al, 2019), fleece yield is 1.5-2.87 kg (Arık et al, 2002;Yıldız and Denk, 2006b;Boztepe, 2015;Kaymakçı, 2016;Tuncer and Cengiz, 2018), birth rate is 0.69-0.94 (Akçapınar et al, 2000;Özbey and Akçan, 2000a;Esen and Özbey, 2002;Ünal et al, 2006;Yakan et al, 2012;Özmen et al, 2015;Güngör and Ünal, 2020;Türkmen and Çak, 2021;Aksoy et al, 2023), the number of lambs born per ram is 0.93-1.03 (Esen and Özbey, 2002;Ceyhan et al, 2019;Aksoy et al, 2023), litter size at birth is 1-1.39 (Akçapınar et al, 2000;…”

Conducted within the National Sheep and Goat Breeding “subproject: Akkaraman Sheep Breeding Project under farmer conditions in Nigde’s Bor district” between 2018 and 2022, the current study evaluated the reproductive characteristics of ewes as well as the livability and growth traits of lambs. This study investigated some ‘reproductive traits’ of an average of 6000 ewes per year and ‘growth performance and ‘survival traits’ of a total of 30051 head lambs. The birth weight (LBW), 60th-day body weight (BW60), 120th-day body weight (BW120), and 120th-day body weight gain (BWG120) of Akkaraman lambs during the study periods were 4.14±0.19 kg, 18.58±0.03 kg, 31.31±0.02 kg, and 246±2.23 g/lamb/day, respectively. In the study, among the factors affecting the growth characteristics of Akkaraman lambs, only the effect of gender on BWG120 and birth type on BW120 was found to be insignificant. In contrast, the other factors were found to be found to be statistically significant. In the study, it was determined that the number of lambs per Akkaraman ewe giving birth between 2018-2022 varied between 1.03-1.10. The highest livability in Akkaraman lambs was determined in 2018 (96.61%) and the lowest in 2020 (83.21%). As a result, it was found that liveability in Akkaraman lambs was dependent on birth year, the age of the ewe, gender, and birth type.
