Fertility and economic indicators of suckler cows
The market activities of suckler cow breeders are focused on the production and sale of calves, of which the impact of cow fertility on the economic performance of the business is obvious. Of the 12 foreign data were of annual sales 84% of sales for calves sold and 16% of sales for animals for slaughter. The requirement for the birth of one calf per cow per year is associated with optimal open days and calving interval, successful conception rate, number of births of calves, calf losses, natural conditions, etc. At birth of 100 calves and losses of 2.5%, 98 calves can be weaned and sold for 14,885 CZK, with birth of 80 calves and 15% loss of 68 calves weaned and sales will be 9,845 CZK per cow and a year. Often evaluation indicator is calving interval. For an extension of more than 365 days, the prolongation loss can be estimated at 710-790 CZK for the cycle and at 34 to 38 CZK per day for a longer calving interval. Of a number of factors that affect fertility and all other indicators of suckler cow breeding, despite the significant advances in mechanization and automation, computer technology, information technology, and other trends, human factors remain the main factor respectively its reliability, hard work, responsibility, and a positive relationship to animals.
