Abstract (2. Language):
The aim of this study was to determine the changes in the serum albumin, alpha 1 (α1)-globulin, alpha 2 (α2)-globulin, beta (β)-globulin, gamma (γ)-globulin, and alpha-lipoprotein (high density lipoprotein-HDL), pre-beta-lipoprotein (very low density lipoprotein-VLDL) and beta-lipoprotein (low density lipoprotein-LDL) and total lipid fractions of the cows in dry period and various stages of lactation period. Fourty healthy, four years old, Holstein dairy cows were used as material. Ten of them were in dry period and the rest were in lacta-tion period. Between the days 48-51, 147-161. and 180. and over of lactation period were accepted as first, se-cond and third stage, respectively. There were 10 cows in each lactation stages. Serum protein and lipoprotein fractions were compared between the dry period, first, second and third stages of lactation period. While signifi-cant differences were determined for α1-globulin, β-globulin, γ-globulin, HDL, VLDL, LDL and total lipid lev-els, no significant differences were observed in albumin and α2-globulin between dry period, first, second, third stages of lactation period

Abstract (Original Language):
Bu çalışmanın konusu kuru dönem ve laktasyonun çeşitli evrelerindeki ineklerin serum albumin, α1-globulin, α2-globulin, β-globulin, γ-globulin, and α -lipoprotein (HDL), pre- β -lipoprotein (VLDL) and β-lipoprotein (LDL) fraksiyonlarındaki ve total lipid değerlerindeki farklılıkları değerlendirmekti. Materyal olarak Karacabey Doğancı Çiftliğinde bulunan 40 adet sağlıklı 4 yaşlı holstein ırkı süt ineği kullanıldı. İneklerin 10 tanesi kuru dönemde, geri kalanlar ise laktasyon dönemindeydi. Laktasyon döneminin 48-51., 147-161. ve 180. ve sonraki günleri sırasıyla I., II., ve III. evre olarak değerlendirildi. Her laktasyon evresinde 10 inek bulunmak-taydı. Alınan kan örneklerinde kuru dönem ve laktasyonunun çeşitli evrelerindeki protein ve lipoprotein değer-leri karşılaştırıldı. Kuru dönem, laktasyonun I., II., ve III. evreleri arasında α1-globulin, β-globulin, γ-globulin, HDL, VLDL, LDL and total lipid düzeylerinde farklılıklar gözlenirken, albumin ve α2-globulin değerlerinde ise herhangi bir farklılık ortaya koyulmadı.
