“…The average prolificacy for the flock of Akkaraman and Awassi was calculated as 117.16±0.01 %. This value was same to 117.00 % for Karacabey merino reported by Sezenler et al (2013), and was similar to that for Karakaş sheep (118.00 %) reported by Ülker et al (2004), but was lower than the prolificacy of Awassi (Öztürk & Pembeci 2016) and Akkaraman ewes (Büyüktekin & Öztürk, 2018), 129.27 and 135.0 % , respectively. Whereas, higher than 114.9 % value reported by Köycü (2017) for Kıvırcık.…”

“…Similar findings have been reported by Trabzon and Öztürk / Selcuk J Agr Food Sci, (2019) 33 (2), 94-98 (Thieme et al 1999;Öztürk & Pembeci 2016;Büyüktekin & Öztürk 2018). According to (Öztürk & Pembeci 2016;Büyüktekin & Öztürk 2018) the effect of dam age on productivity was significant. These findings were not similar with the current study's result.…”

“…The productivity was found as 103.34±0.02 % in the present study. This value is higher than the findings of Özcan et al (2002); (92.8 %) and (Büyüktekin & Öztürk 2018); (86.38 %) for the Akkaraman breed. In contrast, this value was lower than the productivity of Akkaraman (108.23 %) and Awassi (111.40 %) reported by (Öztürk & Pembeci 2016).…”

“…This rate was similar to 87.5 % for Akkaraman reported by (Yalçın & Aktaş 1976). However, this conception rate was higher than reported by (Yıldız & Denk 2006) for Akkaraman (85.19 %), and was lower than that obtained by (Özbey & Akcan 2000) for Akkaraman (93.0%), by Mohammadi et al (2013) for Makooei (93.0%), by (Öztürk & Pembeci 2016) for Akkaraman (91.44 %) and Büyüktekin & Öztürk (2018) for Akkaraman ( 91.27 %).…”

“…The finding of this study about conception rate is in accordance with the reports of (Öztürk & Pembeci 2016). In contrast, (Büyüktekin & Öztürk 2018) were reported as significant. The prolificacy was affected by dam age.…”

In this study, Hasak and Hasmer ewes were used in order to determine the effects of age, year and breed on the conception rate, prolificacy, viability and productivity. The least-squares means for these parameters of all flock were found as follows; 87.27±0.01 %, 117.16±0.01 %, 87.06±0.01 % and 103.34±0.02 %, respectively. In addition, the effects of sex of lamb and birth type on viability were also studied. Except for prolificacy, effects of the age on these parameters were found to be not statistically significant. The maximum prolificacy was obtained with 6-years old ewes. Effect of breed was significant on the prolificacy (P<0.05) and conception rate (P<0.01). With regard to prolificacy, Hasmer ewes were superior to Hasak (120.90 % vs. 113.41 %). The year factor had a significant effect only on the prolificacy (P<0.05). Sex effect on the viability was not significant, but birth type effected viability significantly; single lambs being superior to twin ones.

In this study, progesterone and estrogen hormone levels of Akkaraman (White Karaman/WK) sheep and their effects on some reproductive traits were investigated. The data obtained, from 31 ewes, as 90.32% for lambing, 53.57% for a single birth, 46.42% for twinning, 132.25% for lamb production and 1.46 for litter size. Between the first and second estrus, progesterone levels were found to be between 3.69-12.20 ng/ml for singles and 3.04-10.44 ng/ml for twins; estrogen levels were determined to be between 39.40-84.03 pg/ml for singles and 52.44-72.77 pg ml for twins. The equivalent values at anestrus period of progesterone were 0.20-10.20 ng/ml, and estrogen levels were 6.30-169.60 pg/ml. The effects of birth type on estrogen level were not-significant, while progesterone levels were determined to be significant on the second and third days before the second estrus (P<0.05 and P<0.001). In conclusion, least square means and standard errors and differences between maximum and minimum progesterone hormone levels were similar to those of prolific breeds. Estrogen levels were found lower than prolific breeds but were higher than non-prolific breeds. Therefore, Akkaraman breed can be foreseen as a combine prolific breed.

In this study, the reproductive and growth performance of Akkaraman sheep between 2017-2021 were evaluated within the scope of the National Sheep and Goat Breeding Project in the Hand of the Public, which is being carried out in the province of Nigde. In the research, data obtained from 30923 animals in 22 farms in 7 villages in the central district of Nigde province were used. In the study, the effect of year, dam’s age, gender and birth type on birth weight (BW), live weight on day 60 (LW1), live weight on day 120 (LW2), daily live weight gain (DLWG) on day 120 were investigated. The effects of year, dam’s age, gender and birth type on BW, LW1, LW2, DLWG were found to be statistically significant. While the effects of year, dam’s age and gender were found to be statistically effective on SR, the effect of birth type was found to be insignificant. In the study, fertility, fecundity and litter size in Akkaraman lambs were determined as 0.92, 1.03 and 1.13, respectively. As a result, remarkable progress has been achieved in Akkaraman lambs in terms of performance characteristics (LW1, LW2 and DLWG) between 2017 and 2021.
