The Effects of Docking on Fattening Performance and Carcass Characteristics in Fat-Tailed Norduz Male Lambs
(Elsevier Science Bv, 2006) Bingol, Mehmet; Aygun, Turgut; Gokdal, Ozdal; Yilmaz, Ayhan
The effects of docking on fattening performance and carcass characteristics were investigated using 28 fat-tailed Norduz single-born male lambs raised at the Research and Practice Farm of Yuzuncu Yil University of Van, Turkey. Lambs (n = 13) were docked at 1 day of age with rubber-rings using elastrator. After weaning, lambs were fed concentrates ad libitum for 70 days. Carcasses of slaughtered lambs were chilled at +4 degrees C for 24 h and evaluated for carcass characteristics. Average daily live weight gains of control and docked lambs were 203 and 210 g, respectively. The slaughter and carcass characteristics of the control and docked lambs were as follows: untailed dressing percentages 38 and 43%; kidney and pelvic fat weights 0.07 and 0.11 kg; neck weights 0.6 and 0.7 kg; flank-breast weights 0.76 and 0.98 kg; tail fat weights 3.08 and 1.07 kg, respectively. These differences were significant. Though not significant, corresponding estimates for Musculus longissimus dorsi areas 16.8 and 19.1 cm(2); muscle ratios 42 and 41%; bone ratios 24 and 23%; subcutaneous fat ratios 12.2 and 15.7%; intramuscular fat ratios 3.6 and 3.8%, respectively, were important. The results of this research indicated that docking of fat-tailed Norduz lambs was beneficial in both improving daily live weight gain and carcass characteristics by consumers. (c) 2005 Elsevier B.V.

Effects of Genotype on Testis, Semen Quality, and Mineral Composition of Semen in Various Ram Breeds
(Humana Press inc, 2009) Mert, Handan; Karakus, Kadir; Yilmaz, Ayhan; Aygun, Turgut; Mert, Nihat; Apaydin, Betul; Seyhan, Ercan
This study was carried out on nine 3-5-year-old rams of different species: four Norduz, two Karakas, and three Ile de France x Akkaraman rams. Sperm of each ram was collected by means of an artificial vagina once per month from June to October 2007. In each case, the sperm volume, pH, viscosity, mass activity, motility, concentration, abnormal spermatozoa ratio, and the sperm death/live ratio were recorder along with the animals' testis diameter and scrotum circumferences. The concentrations of calcium, potassium, copper, magnesium, iron, and zinc levels in seminal plasma were determined. There were changes in the measured parameters according to genotype and time of sampling, which can be useful for better planning of anestrous mating programs for these ram species.
Relationship Between Vitamin Composition and Spermatological Characteristics in Semen of Different Ram Breeds of Turkey
(Zoological Soc Pakistan, 2016) Karakus, Kadir; Mert, Nihat; Mert, Handan; Yoruk, Ibrahim; Aygun, Turgut; Tariq, Mohammad Masood
The aim of this study was to evaluate the vitamin levels of ram seminal plasma and the relationship between vitamins and spermatological characteristics. For this aim, nine 3-5 year old rams of Norduz, Karakas and Ile-de-France x Akkaraman (G1) genotypes were provided. Sperm of each ram was collected once per month from June to October of the year 2007 by artificial vagina. In each month, the concentrations of retinol acetate, alpha tocopherol, delta tocopherol, alpha tocopherol acetate and vitamin D-3 in seminal plasma were analyzed by using HPLC. Spermatological characteristics viz. sperm volume, pH, mass activity, sperm motility, abnormal spermatozoid, death/alive ratio and sperm concentration were evaluated. As testicular characteristics, scrotal circumference and testicular diameter were measured. Monthly changes and breed differences on the vitamin levels were statistically insignificant, whereas there was a positive correlation was obtained between testis diameter and retinol acetate levels (p<0.05) and a positive correlation was also estimated between analyzed vitamins. As a result, the relationships between the testicular, spermatological characteristics, and vitamin compositions should be taken into account in the breeding targets.
Some Productive Characteristics and Body Measurements of Norduz Goats of Turkey
(Springer, 2012) Bingol, Mehmet; Gokdal, Ozdal; Aygun, Turgut; Yilmaz, Ayhan; Daskiran, Irfan
Productive characteristics and body measurements of Norduz goats, a native genetic resource in Turkey, were measured. The animals studied were brought from natural habitats to the farm of the Animal Science Department of Agricultural Faculty, Yuzuncu YA +/- l University. Least squares means of withers height (WH), body length (BL), chest width at back of withers (CWBW), chest depth (CD), chest girth (CG) and leg girth (LG) of Norduz does were 65.9 +/- 1.08, 67.2 +/- 1.08, 21.1 +/- 0.88, 30.8 +/- 0.62, 88.9 +/- 1.78 and 60.4 +/- 1.28 cm, respectively. Least squares means of body weights after parturition of does were 41.3 +/- 2.01 kg. The means of lactation length and lactation milk yield were 226. +/- 7.2 days and 347 +/- 40.1, respectively. Twinning rate, fertility, fecundity, litter size and litter size at weaning were 30%, 98%, 1.27, 1.30 and 1.28, respectively. Means of WH, BL, CWBW, CD, CG, LG and body weights of Norduz bucks were 73.9 +/- 2.61, 75.6 +/- 2.23, 21.4 +/- 0.67, 33.9 +/- 1.15, 95.0 +/- 2.34, 69.8 +/- 2.69 cm and 58.7 +/- 3.91 kg, respectively.
