Laktasyondaki tuj koyunlarında serum ve süt sialik asit değerlerinin araştırılması

Bu çalışmada, Tuj ırkı koyunlarda kuru ve kolostrum dönemlerinde serum, laktasyon döneminde serum ve sütte sialik asit düzeylerinin belirlenmesi amaçlandı. Araştırmada hayvan materyalini, KAÜ Veteriner Fakültesi Araştırma ve Uygulama Çiftliğinde bulunan, aynı bakım ve besleme koşullarına sahip, 2-3 yaşında, sağlıklı, 20 baş Tuj ırkı koyun oluşturdu. Serum Total Sialik Asit (TSA) düzeyinde, dönemlere göre istatistiksel anlamda önemli bir fark saptanamadı. Serum Lipid Bağlı Sialik Asit (LSA) düzeyleri ise kuru döneminde, kolostrum ve laktasyon dönemine; kolostrum döneminde de, laktasyon dönemine göre p

An investigation on the serum and milk sialic acid levels of tuj sheep during lactation period

The aim of this study was to determine a) the serum sialic acid levels of Tuj sheep during in dry and colostrum period and b) the serum and milk sialic acid levels during lactation period. Twenty healthy Tuj Ewes in the age group between 2 and 3 years, kept in similar breeding and feeding conditions were the subjects for this study. Ewes were obtained from Kafkas University, Veterinary Faculty Research and Practice Farm. There was no statisticaly significance in total sialic acid (TSA) levels between study periods. Dry period serum lipid bound sialic acid (LSA) levels was the highest in all groups and colostrum period sialic acid level was higher than lactation period (p<0.001). Lactation period serum protein bound sialic acid (PSA) levels was higher than both lactation and dry period (p<0.001). Colostrum period PSA levels were also statistically higher than dry period (p<0.001). Colostrum period milk TSA levels were statistically higher than that of the lactation period milk TSA (p<0.001). As a result, present study first time reports the changes in serum TSA, LSA, PSA and milk TSA levels of Tuj sheep that commonly bred in Kars region.
