Effects Of Calving Season And Lactation Order On Milk Yield And Milk Components In Simmental Cows, Özel Şekerden Jan 1999

Effects Of Calving Season And Lactation Order On Milk Yield And Milk Components In Simmental Cows, Özel Şekerden

Turkish Journal of Veterinary & Animal Sciences

The research was performed to investigate effects of calving season and lactation order on milk yield components and changing of milk components with lactation stage in Simmental cows. Milk samples were taken at AM milkings in 30±15^{th}, 90±15^{th}, 150±15^{th} and 210±15^{th} days of lactations. Lactation stages' effect was found significant level statistically on only the rate of total solid matter (TSM). Calving season's effect was found at significant level statistically on 305-day milk yield; fat, protein, TSM, casein rates and lactation yield of casein. Although lactation order's effect was significant on all the component rates and yields of lactation except …


Blood And Milk Protein Polymorphism And Their Effects On Various Production Traits In Simmental Cows, Özel Şekerden, Faruk Doğrul, Hüseyi̇n Erdem Jan 1999

Blood And Milk Protein Polymorphism And Their Effects On Various Production Traits In Simmental Cows, Özel Şekerden, Faruk Doğrul, Hüseyi̇n Erdem

Turkish Journal of Veterinary & Animal Sciences

This research was carried out to determine the transferrin (Tf) and haemoglobine (Hb) and milk protein (alfa-S_1-casein, beta casein, capa casein, beta lactoglobuline) types, and relationships between Tf and Hb types and milk protein genotypes with various characteristics. The relationship between Tf types and milk yields of control milking and control day were only statistically significant (P0.05). None of the investigated characteristics were effected by milk protein genetic variants at statistically significant level.
