“…The average birth weight (BWT) were found as 4.13 kg varying between 3.91 and 4.33 in the present study. In a study conducted by Bingöl and Aktaş (Bingol 1998;Aktas et al 2014), type of birth and sex of lamb affected BWT significantly. In some other researches, it was reported that age of dam did not have significant effect on BWT (Vanli and Ozsoy 1986;Koncagul et al 2013).…”

This research was conducted to determine some growth reproduction and lactation characteristics of fat tailed Hamdani sheep in extensive farm conditions in the Çığlı village of Çukurca district of Hakkari Province in Turkey. It was found out that average of birth weight, weaning weight and 6 th month live weight were 4.13, 21.78 and 35.09 kg respectively. The average daily gains from birth to weaning and from birth to the 6 th month were 171.98 and 196.30 g respectively. Hamdani, sheep giving birth between December to February, it's reproduction characteristics such as lambing rate, infertility rate, fecundity, twinning rate and litter size were found to be 92%, 8%, 1.04, 13.05% and 1.13 respectively. The survival rates of lambs until the 7 th and 90 th (until weaning) days were 98.5% and 94.6% respectively. The means of lactation milk yield and lactation length for ewes were 83.96 L and 170.98 days respectively. Consequently, it was concluded that Hamdani sheep had a better performance over performance for traits in question compared to Turkish native sheep breeds and some certain cross breeds developed and recently known in Turkey.

“…According to FAO data, Turkey ranks 7 th globally in terms of total sheep population with a stock of approximately 31 million [4] . Of the current sheep population of Turkey, 45% consists of a fat-tailed breed called the Akkaraman, which is bred in the central Anatolia [5] . The Akkaraman breed meets most of the mutton demand in Turkey in spite of low-quality pasture and poor climatic conditions, to which the breed has adapted well [6] .…”

Early live weight in sheep is important for lamb survival and average weight gain until slaughter. The aim of the present study was to investigate association between CAST-MspI, DGAT1-AluI and IGF-1-Bsp143II polymorphisms and early live weights between birth and weaning age in Akkaraman lambs. A total of 374 lambs were genotyped for CAST-MspI, DGAT1-AluI and IGF-1-Bsp143II polymorphisms by the polymerase chain reaction and restriction length polymorphism (PCR-RFLP) method. The results of PCR-RFLP analysis showed that the SNPs had three genotypes of CAST-MspI polymorphism, two genotypes of DGAT1-AluI polymorphism and one genotype of IGF-1-Bsp143II polymorphism of these, CAST-MspI-MM, DGAT1-AluI-CC and IGF-1-Bsp143II-BB were the predominant genotypes in the Akkaraman sheep breed. The result of Chi-square analysis indicated that the Akkaraman sheep breed was in Hardy-Weinberg equilibrium for the investigated polymorphic genes. At the DGAT1 locus, the CT genotype showed significantly heavier birth weight (P=0.044) compared to CC genotype. CAST gene did not show any association for the investigated traits. The results of this study demonstrate that the CT genotype had a positive effect on birth weight in Akkaraman sheep. We concluded that further investigations are needed in DGAT1-AluI polymorphism and live weight at different ages in sheep.

“…Growth curve models provide a set of parameters that describe growth pattern and estimate the expected weight of animals at certain ages. In addition, the parameters obtained from growth functions are highly heritable and have been used in selection studies (Ulutas et al, 2010;Daskiran et al, 2010;Koncagul et al, 2013;Sen et al, 2013;Aktas et al, 2014;Bahreini Behzadi et al, 2014;Kopuzlu et al, 2014;Ghavi Hossein-Zadeh, 2015). Farmers are interested in collecting knowledge of genotypic and phenotypic relationships among weights of lambs during all phases of growth.…”

Changes in live weight or dimension for a period of time are explained by growth curves. The objective of this work was to evaluate the growth curves in lambs of 6 (1 st experimental group) and/or 5 genotypes (2 nd group) created on the basis of Improved Valachian (IV) and Tsigai (T) breed. All lambs (n = 209 and 205) were kept from birth to 9 months of age in identical conditions. Lambs of both experimental groups were weighed at birth and then every week until weaning (8 weightings totally). After weaning only breeding ewe and ram lambs were weighed (6 times totally). The growth of lambs created on the basis of IV a T breeds showed linear course till weaning expressed in regression equation y = 0.2659x + 5.352 and y = 0.2404x + 4.7364 respectively (R 2 = 0.985 and/or 0.9954; x -day of raising). Weight differences between genotypes grew after weaning. The average weight of lambs at the age of 150 days was 40.15 kg in the 1 st group and 38.31 kg in the 2 nd group respectively. The lowest weight was in purebred IV (38.13 kg) a T lambs (34.98 kg) and the highest in the purebred Lacaune lambs (43.82 kg and/or 44.29 kg). Differences between genotypes were statistically highly significant (P < 0.001). The differences among genotypes were even more marked at the age of 9 months. Growth of lambs from birth to the age of 9 months can be expressed in the best way by means of polynomic equation (R 2 = 0.99 in both experimental groups).
