Turkish Journal of Veterinary & Animal Sciences

This study was carried out to investigate the fertility traits, survival rate and growth characteristics of Karayaka and Bafra (Chios x Karayaka B_1) genotypes. Karayaka and Bafra genotypes are raised in the Black Sea region of Turkey. In the study, fertility results for Karayaka and Bafra were determined to be 92.3 and 93.7% for birth rates, and 1.08 and 1.78 for litter size, respectively. The survival rates of Karayaka and Bafra lambs at weaning (90 days) were 93.6 and 91.9%, respectively. The least squares means obtained for Karayaka and Bafra lambs were 3.1 and 3.7 kg for birth weight, 19.5 …

The aim of this study was to determine the effect of GnRH + PGF_{2\alpha} and hCG + PGF_{2\alpha} applications on oestrus and fertility in dairy cows postpartum between days 35 and 45. In this study, 117 healthy, 3-7-year-old Holstein dairy cows from the same farm under similar husbandry conditions were used and they were in postpartum days between 35 and 45. Cows were divided equally into three groups randomly. Group I (n = 39): on day 0, 2000 IU hCG IM (Pregnyl^R, Organon) was given, on day 7, 500 \mug Cloprostenol Na IM (Estrumate^R, DİF), and on day 9, 12.6 …

This investigation was carried out in order to simultaneously compare various production traits of Saanen x hair crossbred goats and pure hair goat flocks under rural environmental conditions. Fecundity, fertility and infertility values for Saanen x hair crossbred and pure hair goats were 1.25, 1.30 and 4.47%, and 0.72, 0.79 and 21.00%, respectively. The effects of genotype, year and age on fecundity, fertility and infertility for Saanen x hair crossbred and pure hair goats were significant (P < 0,01). Birth and weaning weights for Saanen x hair crossbred and pure hair kids were 3.70 kg and 2.63 kg, and 14.68 kg and 12.12 kg, respectively. The effects of genotype, year and age on the birth and weaning weights for Saanen x hair crossbred and pure hair kids were significant (P < 0.01, P < 0.05, respectively). The survival rates for Saanen x hair crossbred and pure hair kids were 95.76% and 78.61%, respectively. Daily average milk yield, lactation length and lactation milk yield in Saanen x hair crossbred and pure hair goats were; 1.83 kg, 201.5 days and 201.77 kg, and 0.56 kg, 143.7 days and 80.47 kg, respectively. The effects of genotype, year and age on the daily average milk yield, lactation length and lactation milk yield for Saanen x hair crossbred and pure hair goats were significant (P < 0.01).
