(Agricultural Research Communication Centre, 2017) Bolacali, Memis; Ozturk, Yahya; Yilmaz, Orhan; Kucuk, Mursel; Karsli, Mehmet Akif
The aim of this study was to determine the effects of genotype and non-genetic factors on the growth traits and survival rates of Turkish indigenous Hair goats (n=63) and their first crosses with Boer bucks (n=91), reared under a semi-intensive management system in the Van province of Turkey. The live weights of the kids at birth and on days 30, 60, 90, 120, 150, and 180 were determined to be 3.64, 8.89, 13.99, 18.97, 23.62, 27.22 and 30.44 kg, respectively. The average daily gains in the pre-weaning, post-weaning and overall periods were 171.09, 136.43 and 148.34 g, respectively. The multiple-birth kids had lower survival rates than the single-birth kids (P<0.01). As a result, it may be recommended to Hair goat breeders in the region to use Boer bucks in cross-breeding in order to ensure a better growth performance from the kids; to apply a sustainable selection program; and to improve management conditions. In addition, the data obtained from this study may be used as a model for designing policies on Hair goat breeding in this region.

(Medwell online, 2008) Bolacali, Memis; Kucuk, Mursel
The aim of this experiment was to determine the fattening performance and carcass characteristics of Angora goat x Coloured mohair goat cross-breed F, male kids (genotype 1) and male Coloured mohair kids (genotype 11). Genotype groups were divided into two sub-groups. Total daily feed intakes of kids in genotype Ia (n = 5) and IIa (n = 9) were 40% concentrate and 60% forage whereas total feed intake of kids in genotype Ib (n = 5) and IIb (n = 9) were 60% concentrate and 40% forage. Fattening lasted 90 days. Daily live weight gains and feed efficiencies (1 kg live weight gain/feed intake) of genotype Ia and Ib were 39.20 and 56.20 g; 8.01 and 7.41 kg, respectively. Daily live weight gains and feed efficiencies of genotype Ila and lib were 53.33 and 79.00 g; 6.64 and 7.41 kg, respectively. Cold dressing percentages, percentages of leg, back, loin and fat on kidney were 40.8, 41.9, 43.3 and 45.5% (p<0.05); 29.2, 31.5, 32.1 and 31.9% (p<0.05); 5.5, 6.0, 6.8 and 6.7% (p<0.05); 5.6, 6.5, 6.1 and 6.4%; 1.6, 3.7, 2.2 and 3.0% (p<0.001) for genotype Ia, Ib, IIa and IIb respectively. It can be concluded that Coloured mohair kids had better daily and total gains and kids fed 60% concentrate had the higher performance compared with others.

(Kafkas Univ, veteriner Fakultesi dergisi, 2012) Bolacali, Memis; Kucuk, Mursel
The aim of this study was to determine the fertility and milk yield characteristics of Saanen goats raised in Mus province, Eastern Anatolia region. This experiment was carried out in Duzova village of Korkut country, Mus. 129 female and 8 male Saanen goats, for first year and 122 female and 7 male Saanen goats for second year (2007-2008) were utilized for mating seasons. Goats were fertilized as free mating in the years 2007-2008 (August-September). Percentages of pregnancy, abortion, birth, single birth and twinning were 90.04, 9.73, 81.27, 42.16 and 57.84%, respectively, kid yields per birth and yields of kids were 1.59 and 129%, respectively. Lactation period, daily milk yield and milk yield per lactation were 273.12 d, 1.37 kg and 383.05 kg. The effects of factors such as year, age and birth types on fertility and lactation of goats were evaluated. In conclussion, the reproduction and milk production data obtained in the current study from Saanen goats raised in Mus province have revealed that Saanen goats can be used for goat milk and kid production in the region.

Investigation of Mohair Production, Clean Yield, and Fibre Characteristics in Coloured Mohair Goat and F1 Cross-Bred Kids of Angora Goat X Coloured Mohair Goat
(Tubitak Scientific & Technological Research Council Turkey, 2009) Odabasioglu, Fuat; Kucuk, Mursel; Yilmaz, Orhan
The aim of this study was to compare some fleece and fibre characteristics of kids of Coloured mohair goat with F 1 crossbred kids of Angora x Coloured mohair goat to reveal the effects of this cross-breeding on mohair production, clean yield, and fibre quality. This study was carried out using goats of the Coloured mohair goat breed at the Experimental Farm of the Faculty of Veterinary Medicine of Yuzuncu Yil University. Four Angora goats were used as male material. In 2001, greasy fleece weight, clean mohair yield, fibre diameter, fibre length, fibre elasticity, breaking strength, kemp fibre content, and medullated fibre content of kids at 12 months of age (36 F-1 cross-bred, 18 pure) were examined. Greasy fleece weight and clean mohair yield were 420 g and 74.3% for kids of Coloured mohair goat, and 830 g and 75.9% for F-1 cross-bred kids. Mean values for fibre diameter, fibre length, fibre elasticity, breaking strength, kemp fibre content, and medullated fibre content were 36.4 mu m, 7.4 cm, 32.4%, 8.2 g, 16.2%, and 13.1% for kids of Coloured mohair goat, and 30.1 mu m, 7.8 cm, 31.6%, 6.3 g, 3.4%, and 2.3% for F-1 cross-bred kids, respectively. The effect of genotype (but not sex) on greasy fleece weight, fibre diameter, breaking strength, kemp fibre content, and medullated fibre content were significant (P < 0.001). Effects of genotype and sex on fibre length, fibre elasticity, and clean yield were not significant (P > 0.05). In conclusion, an overall improvement of mohair production traits was observed on F-1 kids developed by crossing Angora goat and Coloured mohair goat. It could be supposed that Angora goats have been selected more for mohair production compared to Coloured mohair goats. Thus one way to improve the quality of mohair of Coloured mohair goat could be crossbreeding.

(Kafkas Univ, veteriner Fakultesi dergisi, 2012) Ozturk, Yahya; Kucuk, Mursel; Karsli, M. Akif
This study was carried out to compare the growth, slaughter and carcass characteristics of Morkaraman (Pure) and Kivircik X Pure (F-1) (Cross-bred) lambs in semi-intensive condition. At this study 20 Pure and 22 Cross-breed lambs were used for growth traits; 6 male lambs from each group were slaughtered for slaughter and carcass traits. Growth was investigated from the birth to 150th day. The lambs were fed with alfalfa and lamb fattening feeds (days 45). The least squares mean of birth weight and 30, 60, 90, 120 and 150th day weight were 4.06 +/- 0.10 and 4.25 +/- 0.11, 9.93 +/- 0.26 and 8.76 +/- 0.26 (P < 0.01), 16.87 +/- 0.45 and 14.40 +/- 0.45 (P < 0.001), 23.21 +/- 53 and 21.72 +/- 0.52 (P < 0.05), 29.62 +/- 0.64 and 26.69 +/- 0.63, 34.93 +/- 0.80 and 35.85 +/- 0.79 kg. Dressing percentages were 48.49 and 45.03% (P < 0.01); the percentages of leg were 28.36 and 32.23% (P < 0.001); shoulder were 17.04 and 17.51%; back were 5.67 and 7.38% (P < 0.001); loin were 6.14 and 6.26%; others were 24.31 and 28.62% (P < 0.001); kidney were 0.63 and 0.72% (P < 0.001); kidney-pelvic channel fat were 0.64 and 0.95 (P < 0.01); internal fat were 1.21 and 1.73%; fat tail were 15.72 and 4.64% (P < 0.001). The percentages of lean meat in the leg were 64.20 and 65.57%; fat were 15.55 and 13.42%; bone were 20.25 and 21.02%. The percentages of lean meat in the shoulder were 65.64 and 63.00%; fat were 13.55 and 13.90%; bone were 20.82 and 23.11%. The percentages of total meat in the carcass were 48.01 and 55.09% (P < 0.05); fat were 16.21 and 16.96%; bone were 19.55 and 21.44%; and fat percentages in the tailed carcass were 31.93 and 21.55% for pure and Cross-breed lambs respectively. In conclusion; it has been though that Kivircik rams can be utilized for breeding with Pure Morkaraman ewes, commonly found in the region, to obtain lambs with high quality meat at slaughtering age without adaptation problem; and desired lean meat can be obtained via grazing in addition to cross breeding.
Subclinical Pregnancy Toxemia Affects Blood Parameters of Ewes and Impairs Postnatal Growth and Development of Lambs
(Wiley, 2025) Turgut, Ali Osman; Kucuk, Mursel; Irmak, Mehmet; Ozcan, Cahit; Koca, Davut; Gulendag, Erman; Keskin, Ibrahim Halil
Pregnancy toxemia (PT) is a common metabolic disorder that occurs in the last trimester of pregnancy. This study aimed to detect the effects of subclinical PT (SPT) on serum biochemical parameters of ewes and postnatal growth and development of lambs in Romanov sheep. A total of 40 ewes and 69 lambs were included in the study. Blood samples of ewes were collected at the time of parturition to evaluate serum beta-hydroxybutyric acid (beta HBA), serum nonesterified fatty acid (NEFA), cholesterol, and triglyceride. Live weight and body measurements of lambs were recorded at birth (0th day), 30th day, and 60th (weaning) day. In the diagnosis of SPT serum beta HBA concentrations were taken into account. A cut-off value of 0.8 mmol/L for beta HBA was a critical concentration and ewes with 0.8-1.6 mmol/L beta HBA were evaluated as SPT. There were no ewes with Beta HBA value higher than 1.6 mmol/L (clinical PT) in the study. There was no significant difference in serum beta HBA, NEFA and cholesterol concentrations between ewes regarding birth type (single, twin, and triplet). However, triglyceride concentrations were higher (p < 0.001) in ewes giving birth to triplets compared to ewes giving birth to single lamb. Serum beta HBA and triglyceride concentrations were higher (p < 0.01) in ewes with SPT (n = 14) compared to healthy ewes (n = 26). There was no significant difference between ewes with SPT and healthy ewes in serum NEFA and cholesterol. Repeated measures ANOVA results indicated that SPT negatively affected 0th, 30th, and 60th body weights of twin (p < 0.01) and triplet born lambs (p < 0.05). The effect of time on body weights was also found to be significant (p < 0.001). Similarly, most of the body measurements of twin and triplet born lambs were lower (p < 0.05) in the SPT group compared to healthy group. Overall results indicate that SPT may negatively affect postnatal growth and development in Romanov lambs. Because a decline in growth performance has many negative outcomes affecting production traits in sheep, these findings may be valuable for the veterinary field.
