Effect of Frequent Ejaculation on Live Weight and Sperm Characteristics in Norduz Lambs
(Taylor & Francis Ltd, 2006) Bingol, M.; Yilmaz, A.; Cengiz, F.; Kum, D.
To determine the effects of frequent ejaculation on live weight and sperm characteristics, 12 Norduz rams (17 mo) were divided into three groups. The semen samples of the second and third group rams were collected 3 and 5 times per day, respectively, while no semen was collected from the first group. The sperm motility, semen viscosity and mass motility were marginally better in rams of third group (P < 0.05). In both groups semen volume decreased over the days and ejaculate number on the same day. Other parameters were either unaffected or did not follow any definite pattern. It is concluded that live weight of rams and semen characteristics were not affected by taking 3-5 ejaculates in a day in Norduz rams.
Factors Affecting the Growth of Norduz Lambs
(2009) Karakus, K.; Eyduran, E.; Aygun, T.; Cengiz, F.
From the study, it was found that the effects of gender and birth type on birth weight, weights at 30, 60, 90,120,150 and 180th days of age were significant, whereas dam's age had no effect on weights at all periods. Also, the linear regressions of weights at all periods on birth weight were found significant. On conclusion it is stated that sex and birth type had significant effect on weights at all periods, whereas effect of dam age on weights at all periods was found non-significant.
Fleece Yield and Characteristics in White Karaman, Anatolian Merino, Ile De France X White Karaman (G 1 ) and Ile De France X Anatolian Merino (G 1 ) Crossbreds
(Centenary University, 2018) Tuncer, S.S.; Cengiz, F.
This study aimed to determine the some fleece characteristics of the Ile de France X White Karaman and Ile de France X Anatolia Merino crossbred ewes. The study was carried out on 50 heads of White Karaman and Anatolia Merino, 61 head Ile de France X White Karaman and 75 head Ile de France X Anatolia Merino crossbred ewes. According to the study results White Karaman, Anatolian Merino, Ile de France X White Karaman (G 1 ) and Ile de France X Anatolian Merino (G 1 ) sheep were determined respectively; fleece weight (kg) as 2.36, 3.57, 3.14, 3.15; fibre diameter (µ) as 30.99, 25.16, 28.81, 25.47; staple length (cm) as 9.50, 6.85, 8.17, 7.55; straight length (cm) as 19.34, 13.12, 16.34, 14.66; and clean fleece percentage (%) as 69.72, 59.13, 63.84, 65.38. In this study, it was determined that crossbred with Ile de France the fleece weight and fineness in White Karaman, in Anatolia Merino it was found that the staple length and straight length increased. © 2018, Centenary University.

The Growth Traits of Karakaş and Its Crosses Lambs (F1) With Ile De France X Akkaraman (G1) Under Unlimited Suckling Regime
(2006) Gökdal, Ö.; Ülker, H.; Karakuş, F.; Cengiz, F.
In this study, the growth traits of Karakaş and (Ile de France × Akkaraman (G1)) × Karakaş crosses (F1) (IDFAK) lambs were investigated. Ewes in the flock were not milked and lambs were subjected to unlimited suckling regime without weaning. Least squares means of weights of IDFAK and Karakaş lambs at birth and 1-6th months were 4.67 and 4.08 kg (p<0.01), 9.16 and 9.49 kg, 14.87 and 15.44 kg, 22.31 and 24.12 kg, 30.84 and 32.51 kg, 35.34 and 33.79 kg, 39.51 and 35.99 kg, respectively. Least squares means of daily live weight gains of IDFAK and Karakaş lambs from birth to 1., 2., 3., 4., 5. and 6th months of age and between 3-6th months were 0.159 and 0.170 kg, 0.174 and 0.184 kg, 0.198 and 0.219 kg, 0.221 and 0.235 kg, 0.207 and 0.197 kg, 0.196 and 0.177 kg, 0.202 and 0.172 kg, respectively. The survival rates of IDFAK and Karakaş lambs until 60th day were 95.94% and 89.79%, respectively (p<0.05). It seems that (Ile de France × Akkaraman (G1)) × Karakaş crosses (F1) lambs reached to marketing age more short time than Karakaş lambs. It could be concluded that Ile de France x Akkaraman (G1) genotype is useful in improving lamb production in Karakaş sheep and desired growth could be obtained especially for cross lambs during 5th and 6th month age. © 2006 Asian Network for Scientific Information.
Phenotypic Correlations Among Fleece Traits in Norduz and Karakas Sheep
(2011) Kor, A.; Karakus, F.; Tuncer, S.; Yilmaz, A.; Bingol, M.; Cengiz, F.
In this research, it was aimed to determine the phenotypic correlations among some physical traits of Norduz and Karakas sheep. Animal material was consisted from 2-6 years of age of breeding flocks of 50 Norduz and 50 Karakas ewes. Traits measured were greasy fleece weight, fiber diameter, clean fleece percentage, staple length, single fiber actual length, single fiber natural length, breaking strength, elasticity and the number of crimp in 2.54 cm. There was a positive correlation between clean fleece percentage and fiber diameter, it was insignificant for both genotypes. The estimated phenotypic correlations between staple length and greasy fleece weight was 0.403 (p<0.01) and 0.445 (p<0.01) in Norduz and Karakas sheep, respectively. It was understood that traits like fiber diameter, length, fleece weight and the number of crimp should be evaluated together in breeding studies on fleece yield in Norduz and Karakas sheep. © Medwell Journals, 2011.
Usage of Factor Scores for Determining Relationships Among Body Weight and Some Body Measurements
(Scientific Issues Natl Centre Agrarian Sciences, 2009) Eyduran, E.; Karakus, K.; Karakus, S.; Cengiz, F.
The aim of this study is to estimate weaning weight (WW) using six body measurements (withers height (WH), body length (BL), chest circumference (CC), leg circumference (LC), body depth (BD), and width of chest behind shoulders (WCS)) measured at weaning period by factor scores in multiple regression model. For this aim, a total of 94 Norduz lambs were used. "Kaiser-Meyer-Olkin (KMO) measure of sampling adequacy" and Bartlett's test of sphericity were used to determine whether factor analysis was suitable for data studied. According to results of these criteria, the data was found to be most appropriate for applying factor analysis. Three factors whose eigenvalues greater than 1 were selected as independent variables for multiple regression analysis. It was concluded that that three factors had significant-positive effects on weaning weight and all three factors explained approximately 80% of variation in weaning weight.
