In this study, the growth, age composition, sex ratio, condition factor and spawning period of whiting (Merlangius merlangus euxinus Nordmann, 1840) on the eastern part of the Trabzon-Yomra coast were investigated. During the study, a total of 1730 fish (1122 females and 608 males) ranging in age from group I to IX were examined. The chi squared test was used to calculate ratios between female and male specimens and no significant difference was found (P>0.05), and the relative growth length and the relative growth weight differences between females and males were not found to be statistically significant (P>0.05). …

Studies On The Possibility Of Improving Lamb Production By Two-Way And Three-Way Crossbreeding With German Black-Headed Mutton, Kıvırcık And Chios Sheep Breeds 1. Fertility, Lamb Survival And Growth Of Lambs, Mustafa Özcan, Ahmet Altinel, Alper Yilmaz, Hali̇l Güneş
Turkish Journal of Veterinary & Animal Sciences
The aim of this study was to compare the fertility of ewes and the survival and growth traits of lambs which were produced by two-way and three-way crossbreeding with Kıvırcık sheep, the predominant breed in the Marmara region, Chios sheep, the most prolific breed in the region and German Black-Headed Mutton (GBM), the mutton breed which exhibits the best adaptation to the environmental conditions of the region. In the study, it was determined that the fertility of the Kıvırcık, GBM x Kıvırcık and GBM x F_1 (Chios x Kıvırcık) genotypes were 76.66%, 81.13% and 85.29% for pregnancy and birth rates; …

The effects of outdoor raising on the survival and growth of Simmental calves in individual hutches were studied at Kazova State Farm, the location having a mixture of Black Sea and semiarid continental climate conditions. A total of 63 female calves born in each of the four seasons between March 1996 and February 1997 were used. The animals were kept in individual hutches for 3 months (preweaning period) and then in groups of 10 until 6 months of age (postweaning period). The mean birth weight was 38.92 kg, while average birth weights for the seasons ranged from 37.70 to 40.44 …
