Öğe Comparison of two sampling methods for assessing wool properties in Awassi sheep -- 2(1998) Dag B.; Boztepe S.Midside sampling of wool is not the standard method of sampling fleeces in Turkish laboratories. Different wool sampling methods were compared with respect to fleece traits in Awassi sheep with coarse-mixed wool. Wool samples were taken from the shoulder, hide and rump areas (Method 1) and from the last rib of the body (Method 2). Staple length, fibre length, crimp, fibre diameter and yield values were determined in each sample. Mean values for methods 1 and 2 were: 11.9 and 11.6 cm staple length, 15.1 and 15.4 cm fibre length, 9.0 and 9.2 average number of crimps over a length of 5 cm, 31.3 and 31.9 ?m fibre diameter, 70.20% and 69.50% wool yield, respectively. These differences were statistically non significant so last rib area means (Method 2) were equivalent to three area means (Method 1). Evaluation of samples by using method 2 is easier than method 1so it is to be recommended.Öğe Effect of supplementation of ovine oviductal cells with LH and gestradiol-17? on embryo development(2008) Ciftci H.B.; Zulkadir U.; Boztepe S.; Ozturk A.; Dag B.; Yetisir R.The aim of this research was to study the effect of supplementing the oviductal cells with Luteinizing hormone (LH) and Oestradiol - 17? (E 2) on sheep embryo development in vitro. Addition of 5?g/ml LH, 5?g/ml E2 to embryo culture significantly increased the percentage of embryos over the control group. Addition of LH and E2 to the culture of zygotes containing oviductal cells, caused further significant increases in the percentages embryos at morulae, blastocyst and hatched stages over the control and LH-E2 added group by 28.75, 19.88 8.89% and 15.58, 11.91, 6.39% respectively.Öğe Effects of different stocking and lighting regimes on fattening performance and sexual maturity of Japanese quail (Coturnix coturnix japonica) [Japon bildircinlarinda (Coturnix coturnix japonica) farkli yerleşim sikli?i ve aydinlatma programlannin besi performansi ve cinsel olgunluk yaşina etkileri](1996) Yazgan O.; Boztepe S.; Öztürk A.; Parlat S.S.; Da? B.The effects of different stocking densities and lighting regimes on fattening performance and sexual maturiy in Japanese quail ae determined. A total of 720 chicks were caged in three separate rooms 9 m2 in size. Twelve treatments consisting of three lighting regimes: 24 (L1). 16 (L2) and 8 (L3) hours light/day, and four stocking densities: 240 (D1), 144 (D2), 103 (D3) and 80 (D4) cm2/bird were applied. The experiment was a completely randomized design with factorial arrangement of treatments. Two replicates of each treatment were used. Performance characteristics were determined at the first day of each week at almost the same time during the five-week experimental period. The time at which 50% of the birds rearched egg and sperm production was accepted as the age at sexual maturity. Avegare live weight of treatment : L1, L2 and L3 were 178.3, 174.6 and 165.5 g and average daily live weight gains were 5.8, 5.6 and 5.3 g. respectively. Average feed efficiency for L1, L2 and L3 were 3.72, 4.05 and 4.00 g, respectively. The same parameters for different stocking rates : D1, D2, D3 and D4 were 4.17, 4.01, 4.02 and 3.50 g, respectively. Age at sexual maturity in L1, L2 and L3 treatments were 27, 31 and 50 days for male qualis and 39, 39 and 62 days for female quails, respectively. Fattening performance and sexual maturity were affected by lighting regimes, but feed efficiency was not affected statistically. Effect of stocking density on feed efficiency was found to be statistically significant, but its effect on sexual maturity was not significant.
