Vliv délky mezidobí na tržní produkci mléka dojnic českého strakatého plemene skotu
 Šmejkalová, Kristýna
This bachelor´s thesis deals with various influences on the dairy market. Into these selected impacts were included: the length of the calving interval, the lactation phases and also the lactation sequence. When examining the length of the calving interval, it was found out that the length of the calving interval strongly influences the amount of milk production. With the increasing length of the calving interval the quantity of milked milk rose from 8 249 kg up to 12 180 kg and also the revenues rose from 59 228 CZK up to 87 452 CZK. I have also studied the phase of the lactation and I can say that with the increasing stage of lactation the milk performance decreased from 100% to 65%. I have also noticed that the highest milk performance is on the 3rd and higher lactation when the average milk yield has increased at first lactation from 5,749 kg to 8,105 kg, and revenues increased from 41 278 CZK to 58 194 CZK.
