Öğe Beziehungen zwischen der Woll- bzw. Milchleistung und einigen biochemischen Parametern beim Konya-Merinoschaf(BLACKWELL WISSENSCHAFTS-VERLAG GMBH, 1992) Serpek, B; Akmaz, A; Tekes, M.A; Başpınar, N; Tıftık, A.M; Kadak, R; Inal, S; Eröz, SCorrelations had been calculated for 57 or 52 Konja-Merinosheep between wool or milk performance respectively and the concentration of glutathione in red blood cells, the potassium content of blood and the serum concentration of serum-ceruloplasmin. Significant negative differences were found between the parameters: Potassium or milk performance respectively and Glutathion and wool solidity. Positive significances were found for Ceruloplasmin, weight of wool, wool quality, elasticity and solidity. It has to be clarified whether genetic correlations exist between the biochemical parameters and the criteria of performance, which may be used for breeding purposes.Öğe Comparisons of serum somatotropin, 3,5,3 '-triiodothyronine, thyroxine, total protein and free fatty acid levels in newborn Sakiz lambs separated from or suckling their dams(KARGER, 2005) Firat, A; Ozpinar, A; Serpek, B; Haliloglu, SObjective: To determine the effects on serum somatotropin, 3,5,3'-triiodothyronine (T-3), thyroxine (T-4), free fatty acids (FFAs) and total protein levels of different feedings and age in Sakiz sheep that have a high twin-bearing rate supported by estrous synchronization. Methods: 20 newborn lambs were used in the study. Lambs were divided into 2 equal groups. The lambs in 1 group were separated from their dams following parturition, and those in other group were kept together with their dams. Separated lambs were fed commercial cow's milk for 2.5 weeks. After that, they were fed a milk substitute, hay and concentrated supplement for 2 months, and from the end of the 2 months they were fed hay and concentrated supplement. The lambs in other group were kept together with their dams only during the day and in addition were fed hay and concentrated supplement. After 2 months, they were maintained feeding only on hay and concentrated supplement. Blood samples were taken from vena jugularis of lambs at 12 and 24-48 h, and 14, 28, 42 and 56-90 days after parturition. Serum samples were analyzed for somatotropin by enzyme immunoassay, for T-3 and T-4 by radioimmunoassay, and for total protein and FFA by a spectrophotometric method. Results: Serum somatotropin levels were insignificantly different between the lambs with and without their dams. Serum T-3 levels were generally lower in the separated lambs than those in other group. Serum T-4 levels were significantly lower in the separated lambs 48 h and 90 days after parturition than those in other group. Serum FFAs were insignificantly different between 2 groups. Serum total protein concentrations were lower in the separated lambs than lambs kept together with their dams (significantly at 12 and 48 h and 14 days). Conclusion: Ingestion of colostrum and dam milk markedly affected serum total protein levels, but body weight and serum somatotropin levels were insignificantly affected. Also serum T-3 and T-4 levels markedly decreased with advancing age. Serum FFA levels were not affected by the trial. Copyright (C) 2005 S. Karger AG, Basel.
