    The aim of the study was to evaluate the milk yield parameters of imported Estonian and American Holsteins in response to same sire insemination. The means for 305-day milk yield produced by the groups were between 8180 and 10851 kg, which points out a yield higher than most of those reported in the literature. American Holsteins were superior to Estonian cows with 2036 kg more milk in the first and 1147 kg in the second lactation period. For environmental factors, calving age itself had no augmenter effect on milk yield unless it was accompanied by parturition. The calving season and dam age had no significant effect on milk yield, but longer dry periods generally resulted in more milk yield. Fat, protein and lactose components were determined as 3.7, 3.3 and 4.6% during the first and second lactation periods. As a result, the imported breeds produced high milk yield performance with optimal components in Nigde province.

    Effect of peppermint (Mentha piperita) supplementation on carcass yield, meat taste, heart weight, liver weight and some blood parameters in laying quail (Coturnix Coturnix Japonica) (2)
    (Agricultural Research Communication Centre, 2016) Çetingul, İbrahim Sadi; Bayram, İsmail; Kucukkurt, İsmail; Akkaya, Abdil Burhaneddin; Uyarlar, Cangir; Yardımcı, Mehmet; Rahman, Abdur
    This study was carried out to determine the effects of peppermint (Mentha Piperita) on blood parameters (cholesterol, triglyceride (TG), high density lipoprotein (HDL), low density lipoprotein (LDL), malondialdehyte (MDA), antioxidant activity (AOA), total protein, glucose, carcass yield, heart, liver weights and organoleptic control of the carcasses in laying quails. A total of 180 15 week old laying quails were used in the study. There were 5 experimental groups which were supplemented with different ratios of Peppermint up to 5%. The control group received no peppermint supplements. The experiment continued for 10 weeks. Antioxidant activity and HDL amounts increased (P<0.05) in parallel with the increase of peppermint supplementation, while LDL, glucose, MDA amounts decreased (P<0.05) with the increase of supplemented peppermint. No effects were observed (P>0.05) on the carcass quality with a 5 % peppermint supplementation to the diet. In conclusion, the supplementation of peppermint to diets up to a 5% level was found to be quite beneficial in terms of blood parameters such as MDA, AOA, LDL, and HDL.
