OZEL SEKERDEN

Abstract: The objectives of this study were to investigate environmental factors on urea concentration, acidity, density and pH of Anatolian Buffaloes milk. As a total of 115 milk samples from 53 cows that were calved in 2004 and 2005 in 8 units of Il?kp?nar Village were collected in morning milkings in June, September,
December and March. The cows were on their lactation days 30±15, 60±15, 90±15, 120±15, 150±15, 180±15, 210±15, 240±15 and 270±15. The milk samples were analysed for pH, acidity, urea content. Urea content was determined using photometric method. Data were classified as follows; lactation stages: 1 (30±15, 60±15, 90±15 days): 2 (120±15, 150±15, 180±15): 3 (210±15, 240±15, 270±15); calving year: 1 (2004), 2 (2005); calving season: 1 (January-May), 2 (September and October); month of samples collection: 1 (June), 2 (September), 3 (December), 4 (March); lactation order: 1 and 2 : 1, 3 and 4: 2, 5 and 6: 3. Effects of environmental factors on each variable were investigated separately and analysed using analysis of variance. Production mounth on all the characteristics; calving year and lactation stage on most of the characteristics; unit and calving season on some of the characteristics were found to be effective significantly.
