Publication Effect of sex on fattening performance and carcass characteristics in kivircik lambs(Kahramanmaras Sutcu Imam Univ Rektorlugu, 2021-01-01) Koyuncu, Mehmet; KOYUNCU, MEHMET; Altincekic, Seniz Ozis; ÖZİŞ ALTINÇEKİÇ, ŞENİZ; Duru, Serdar; DURU, SERDAR; Canbolat, Onder; CANBOLAT, ÖNDER; Ziraat Fakültesi; 0000-0001-9044-8092; 0000-0001-5243-4458; I-9517-2017; AAG-8210-2021; JPL-0865-2023The aim of this study was to evaluate the effect of sex on fattening performance and carcass characteristics of Kivircik lambs. Fifty head weaned Kivircik lambs, half males and half females, were used in fattening period. After weaning, the growth and feed consumption of the male and the female lambs fattened for 56 days were recorded. Average daily weight gain differed significantly (P<0.01) between the males and the females (294.9 and 214.2 g, respectively). A total of 10 lambs (5 males and 5 females) were slaughtered and the left side of the carcasses was cut into five joints. Dressing percentage (hot/cold) based on full weight and empty body weight were lower (P<0.05) for the males than the female lambs. Sex had a significant effect on kidney-knob and channel fat weight, M. longissimus dorsi section area (MLDA) and liquid expelled (P<0.01). Sex primarily affected the quantity of all types of fat deposits. The male lambs had higher muscle, muscle/bone and muscle/total fat ratios than females.Publication The effects of short-mid-long term intravaginal sponge application on reproductive performance of Karacabey merino ewes in the anestrous season(Agricultural Research Communication Centre, 2019-01-01) Altincekiç, Seniz Öziş; Koyuncu, Mehmet; ÖZİŞ ALTINÇEKİÇ, ŞENİZ; KOYUNCU, MEHMET; Ziraat Fakültesi; Zootekni Bölümü; 0000-0001-9044-8092; AAG-8536-2021; JPL-0865-2023; AAG-8210-2021The aim of the present paper was to investigate the efficiency of different progestagen treatment methods in combination with Pregnant Mare Serum Gonadotrophin (PMSG) in Merino ewes outside the breeding season. A total of 78 ewes (2 to 4 years old) with a mean bodyweight of 58.4 kg and an average body condition score (BCS) of 3.5 were used in the trial. The ewes were randomly divided into 3 equal groups [n=26]. Intravaginal progestagen sponges containing Fluorogestone Acetate (FGA; 30 mg) were inserted intravaginally for different periods (7_days: short-term; 10_days: mid-term, 14_days: long-term). In all cases, 500 IU PMSG was administered intramuscularly at sponge withdrawal. The oestrus response, lambing rate, multiple birth rate, fecundity and litter size were [65.4, 61.5, 18.8 %, 0.77 and 1.25] in the short-term group; 80.8, 88.5, 34.8 %, 1.31 and 1.48 in the mid-term group; and 96.2, 92.3, 62.5 %, 1.50 and 1.63 in the long-term group, respectively. Oestrus manifestation and multiple birth rate were greater in long-term than in mid-and short-term groups, whereas for lambing rate, fecundity and litter size, better results were obtained in long- and mid-term than in short-term protocol. In conclusion, in Merino ewes, oestrus synchronisation outside the breeding season with long and mid-term progestagen treatment was found to be more effective than short-term treatment.Publication The effects of short-mid-long term intravaginal sponge application on reproductive performance of Karacabey Merino ewes in the anestrous season(Agricultural Research Communication Centre, 2019-01-01) Altınçekiç, Şeniz Öziş; Koyuncu, M.; ÖZİŞ ALTINÇEKİÇ, ŞENİZ; KOYUNCU, MEHMET; Ziraat Fakültesi; Hayvan Bilimleri Bölümü; 0000-0001-9044-8092; 0000-0003-0379-7492; AAG-8210-2021; AAG-8536-2021; JPL-0865-2023The aim of the present paper was to investigate the efficiency of different progestagen treatment methods in combination with Pregnant Mare Serum Gonadotrophin (PMSG) in Merino ewes outside the breeding season.

BCS was assessed 1 day after lambing, based on a scale of 1-5, by palpation of muscling and fat deposits over and around the vertebrae in the loin region. The data set was analyzed using a model that included body condition score, live weight of ewes, as well as other factors that affected productive traits. The results showed that the overall mean ewe BCS at lambing, ewe live weight, birth weight, weaning weight and daily live weight gain (from birth to weaning) were 2.9, 57.1 kg, 4.5 kg, 23.6 kg and 0.249 kg, respectively. As a result of the analyses, the relationship between body condition score and ewe lambing weight, birth weight and daily live weight gain of lamb were found to be 0.440, 0.301, and 0.219, respectively (P< 0.01; P> 0.05). The effect of ewe BCS was only significant (P< 0.01) effect on lamb birth weight. According to the results, BCS at the end of the gestation period should be at least 3.0-3.5 and also this condition should be maintained during the period of gestation in Kivircik ewes.Publication Estimation of breeding values and genetic trend of some growth traits in Merino sheep(Elsevier, 2022-06-03) Altınçekiç, Şeniz Öziş; Oral, Hülya Hanog; Duru, Serdar; ÖZİŞ ALTINÇEKİÇ, ŞENİZ; DURU, SERDAR; Ziraat Fakültesi; Zootekni Bölümü; 0000-0001-9044-8092; 0000-0001-5243-4458; I-9517-2017; AAG-8210-2021The aim of this study was to estimate the genetic trends for growth traits of Merino sheep managed under the National Sheep and Goat Improvement Project's breeding program. the analysis included data belonging to 3116 lambs born to 83 rams and 1129 ewes. The data [birth weight (BW), live weight at 45th day (LW45), weaning weight (WW-90th day) and average daily gain from birth to weaning (ADG)] were collected over a period of 6 years. BW demonstrated a positive and significant genetic correlation with all growth traits, but had a low direct heritability (0.02 +/- 0.02). Birth weight had high genetic correlation with all growth traits. Except for the high correlation between LW45 and WW (0.51), the remaining traits had medium or low phenotypic correlations. While the genetic trend values for LW45 in lambs, ADG, WW and growth index (GI) in rams and ADG, LW45 and GI in ewes were all positive, they were not statistically significant. However, the genetic progression for GI, WW and ADG in lambs were found to be negative and significant (p < 0.05). Genetic trend estimates indicated that there wasn't a positive genetic improvement in the growth traits studied in Merino sheep. Thus, it is proposed to improve genetic trends by the implementation of selection as based on BLUP.Publication Effects of different protocols for estrus synchronization in ewes on vaginal pH, estrus time and reproductive performance and change in vaginal electrical resistance values(Polska Akad Nauk, 2022-01-01) Altınçekiç, Şeniz Öziş; ÖZİŞ ALTINÇEKİÇ, ŞENİZ; Ziraat Fakültesi; Zootekni Bölümü; 0000-0001-9044-8092; JPL-0865-2023; AAG-8210-2021This study examined the effects of different intravaginal apparatus types used for estrus cycle management in ewes, as well as the timing of their insertion and withdrawal on vaginal pH and reproductive performance. Additionally, this study aimed to investigate changes in VER levels during estrus and anestrus in Kivircik ewes. A total of 90 Kivircik ewes in the estrus period were synchronized using fluorogestone acetate (FGA) sponges and controlled internal drug release (CIDR) protocols ranging from short (5 days) to medium (9 days) up to long-term (13 days). Additionally, 350 IU of equine chorionic gonadotropin (eCG) were injected intramuscularly when the FGA and CIDR were withdrawn from all the groups. Vaginal pH samples were taken on the days of vaginal apparatus removal (days 5, 9 and 13), as well as the first day of estrus and anestrus. Vaginal pH increased more markedly in ewes treated with FGA and CIDR when compared to those in anestrus, especially in the medium and long-term treated ewes, which had a pH value around 7.7. Both medium and long-term protocols had a high success rate for estrus occurrence, with all the tested ewes entering estrus. However, ewes in the FGA medium-term group presented the earliest estrus at 32.8 hours. Although statistically non-significant, the CIDR protocol resulted in numerically higher results for multiple birth rate, fecundity and litter size. The electrical resistance of vaginal mucus was measured during anestrus and immediately after estrus detection. VER values were recorded to be lower during estrus. VER values between 200 and 300 Omega might be indicative of estrus in ewes.Publication Determination of t3, t4 and cortisol levels in cidr applied kivircik and karacabey merino ewes(Univ Namik Kemal, 2018-01-01) Öziş, Altıncekic, Seniz; KOYUNCU, MEHMET; ÖZİŞ ALTINÇEKİÇ, ŞENİZ; Koyuncu, Mehmet; DURU, SERDAR; Duru, Serdar; Ziraat Fakültesi; Zootekni Bölümü; 0000-0001-9044-8092; 0000-0001-5243-4458; JPL-0865-2023; I-9517-2017; AAG-8210-2021; AAG-8536-2021This study has been conducted in order to determine whether the CIDR application on Kivircik and Karacabey Merino ewes used for supplying estrous synchronization a stress factor or not. For this purpose; T3 (triiodothyronine), T4 (thyroxine) and cortisol hormone levels of sheep in their blood samples were measured on day 1 when CIDR apparatus were mounted, on day 7 and on day 14 when they were removed. In this study, 80 head of ewes in total were used which consisted of 40 head Kivircik and 40 head Karacabey Merino ewes. 10 ml of blood from jugular veins of sheep were taken at the specified periods into EDTA tubes, and their T3, T4 and cortisol concentrations were identified by commercial RIA kits. In Kivircik race, these values were identified as 1.76 (ng/mL), 7.92 (mu g/dL), 5.30 (mu g/dL) respectively while in Karacabey Merino race as 1.69 (ng/mL), 7.00 (mu g/dL) and 4.19 (mu g/dL) respectively. In terms of T4 and cortisol, the difference between races were found significant (P<0.01) while difference between the periods were found significant only for T3 hormone (P<0.01).Publication Reproductive performance with short-time controlled internal drug release (cidr)-based synchronization protocol for fixed-time artificial insemination in nulliparous and primiparous saanen goats(Polska Akad Nauk, Polish Acad Sciences, Univ Warmia & Mazury Olsztyn, 2022-01-01) Altıncekiç, S. Öziş; ÖZİŞ ALTINÇEKİÇ, ŞENİZ; Koyuncu, M.; KOYUNCU, MEHMET; Ziraat Fakültesi; 0000-0001-9044-8092; AAG-8210-2021; JPL-0865-2023In this study, it was aimed to evaluate the reproductive performance of primiparous and nulliparous Saanen goats following the insemination made ceivically via frozen commercial buck semen with short-time controlled internal drug release (CIDR, Eazi-Breed. Pfizer)-based synchronization. In the study, a total of 50 Saanen goats, 26 of which were aged 9 months and 24 of which were aged 2 years, were used. The CIDRs including 0.33 g of progesterone were applied to all the goats for 7 days and while the CIDRs were taken out of the vagina, the 500 IU equine chorionic gonadotropin (eCG) was injected intramuscularly. The first dose was administered in a fixed-time manner with mini straws of 0.25 ml including 300x10(6) motile frozen spermatozoa 24 hours after the injection without making estrus detection, and the second dose insemination was applied 24 hours later. In the study, although the pregnancy rate, fecundity, prolificacy and multiple birth rate values (83%, 1.25, 1.50 and 60%) obtained in the primiparous goats were found to be higher than those found in the nulliparous age group (80%, 0.84, 1.05 and 38%), they were not statistically significant. It was concluded that the effects of the CIDR-based double-dose insemination applications in the primiparous and nulliparous Saanen breed goats in breeding season for 7 days on fertility were similar and the cervical insemination method, a quick and more practical option compared to the intrauterine insemination, could be used successfully in both age groups.Publication Effects of non-genetic factors on growth traits and survival rate in Karacabey Merino lambs(Polska Akad Nauk, 2023-01-01) Oral, H. Hanoğlu; Altınçekiç, S. Özis; Duru, S.; ÖZİŞ ALTINÇEKİÇ, ŞENİZ; DURU, SERDAR; Ziraat Fakültesi; Zootekni Bölümü; 0000-0001-9044-8092; 0000-0001-5243-4458; I-9517-2017; AAG-8210-2021This study was conducted with the aim of determining the growth characteristics and survival rate of Karacabey Merino lambs, as well as the non-genetic factors affecting these traits. The study included data from a total of 17659 lambs and 12263 ewes raised in 30 herds between the years 2011 and 2016 as part of the National Sheep and Goat Improvement Project. The aver-age birth weight of the lambs was determined as 3.73 +/- 0.05 kg, the average 45th day live weight was 18.43 +/- 0.58 kg, the average weaning (average 91.8 days) weight was 31.83 +/- 0.24 kg, and the average daily live weight gain until weaning was 289.1 +/- 3.91 g. The average survival rate of lambs at weaning was calculated to be 95.67% +/- 1.15. The effects of the factors herd, birth year, birth type, birth season and sex were found significant for all traits (p<0.01). It was established that the mortality rate in lambs in large herds was higher during 6 years in which the project was carried out. Due to the high twinning rate in large herds, the number of lambs per worker is increased, and as a result, they cannot be adequately cared for. For this reason, large farms may be encouraged to increase workmanship services in addition to being provided with protective health practices for lambs throughout the birth period. On the other hand, it was determined that the twinning rate was low in small farms. On farms with fewer sheep populations, it may be advised to flush or administer exogenous hormone treatments to ewes in order to increase fertility and help them bear twins.Publication Effects of CIDR, vitamin A, E(Kahramanmaraş Sütcü İmam Üniversitesi Rektörlüğü, 2019-01-01) Koyuncu, Mehmet; Altınçekiç, Şeniz Öziş; Nageye, Farida İbrahim; KOYUNCU, MEHMET; ÖZİŞ ALTINÇEKİÇ, ŞENİZ; Nageye, Farida İbrahim; Ziraat Fakültesi; Zootekni Bölümü; 0000-0001-9044-8092; AAG-8210-2021; JPL-0865-2023; AAG-8536-2021This study was conducted to review the effects of CIDR vitamin A, E + Se administration on fertility and lamb performance on Kivtrcik ewes during anestrus season. The ewes were randomly assigned into 5 groups. Animals in group 1 served as GDR containing 0.33 g progesterone were inserted into vagina and then removed after 14 days. Following the removal of vaginal apparatuses and PGF2 alpha injection, intramuscular 500 IU Pregnant Mare Serum Gonadotrophin (PMSG) was injected in 20 head of ewes. Animals in group 2 were administered CIDR + Vitamin A + Vitamin F in 20 head of ewes. Animals in group 3 were administered Vitamin A (2ml/head) in 20 head of ewes. Animals in group 4 were administered Vitamin E + Se (2ml/head) in 20 head of ewes. Animals in group 3 served as control in 18 head of ewes. After 24 hours as of application, rams were added in the herd. Results of pregnancy rate (95.0%, 100.0%, 100.0%, 100.0%, 83.3%), lambing rate (95.0%, 100.0%, 100.0%, 100.0%, 83.3%) and prolificacy (21.1, 30.0, 5.0, 10.0, 0.0) were found for ewes of CIDR, CIDR + Vitamin A, E + Se, Vitamin A, Vitamin E + Se administered ewes and control groups, respectively. It can be concluded that administration of CIDR, Vitamin A and E + Se alone and in combination improved reproductive performance on Kivircik ewes.
