Abstract:

In this study, 4589 milk productivity records held between 2007 and 2017 of Black Alaca cattle in 389 enterprises members of the Kırşehir or Damızlık Cattle Farmers Association were used. 305 days of milk productivity (305 GSV), lactation time (LS) and drought time (KKS) and the effects of the year of lactation, the order of lactation, the season of lactation, the operating factor and the age of lactation. In the study, the average of 305 GSV, LS and KKS were calculated as 7350,5±30,70 kg, 398,2±1,61 days and 62,5±17,02 days respectively. The impact of the year of deforestation, the order of lactation, the season of deforestation and the operating size on 305 GSV and LS is statistically important (p<0,01). The influence of the year and operating size on the KKS is significant (p<0,01) and the influence of the laktation order and the season of the laktation is unimportant (p>0,05). In the study, the phenotypic direction of 305 GSV was 62.6 kg according to birth years. As a result, this study has determined the milk productivity characteristics of Black Alaca cattle grown in the province of Kırşehir. In the years, there have been significant statistical differences in terms of 305 GSV.
