  The aim of the study, was to investigate the effects of vitamin E and heat stress on the metabolism of laying hens. In the study, 120 Leghorn line laying hens were used. The study was carried out in 9 weeks and divided into 3 periods. The hens were divided into 2 groups. The control and experimental groups were subdivided into 3 groups of 20 hens each. The hens in the subgroups were fed the standard full feed layer ration supplemented with extra 50 and 75 mg kg-1 vitamin E, respectively. The temperature of the room of the experimental groups was raised to 35°C during the second period. It was verified that heat stress lead to significant increase in plasma total protein, albumin, total lipid and cholesterol concentrations during the second period of the experiment. As a result, it might be concluded that supplementing vitamin E to the diet during heat stress does not have any positive effect on the metabolism.

  The current study was undertaken to determine the relationship between milk production traits of Eastern Anatolian Red (EAR) and South Anatolian Red (SAR) breed cows and polymorphisms of Growth Hormone gene (GH) which is a potentially effective Quantitative Trait Loci (QTL) on milk production traits. Fifty cows that were newly delivered calves from each of EAR and SAR breeds were used. Triplicate milk samples were obtained between 0-30, 50-180 and 270-300 days of lactation period. Milk samples were analyzed for milk fat, protein, dry substance, refraction indices and somatic cell count. In addition, DNA samples were obtained from blood samples of each cow and AluI and MspI polymorphisms in GH were determined using PCR-RFLP method. In both breeds, AluI polymorphism with VV genotype cows had higher milk fat percentage compared to other genotypes. Similarly, in SAR cows, those with MspI polymorphism and -/- genotype had higher milk fat percentage compared to other genotypes. The relationship between GH gene polymorphisms and other milk quality parameters could not be established. As a result, it can be concluded that GH gene polymorphisms can be of a valuable parameter to be used for selection of EAR and SAR cows for improving milk fat percentage.
