Empties leave and in calf heifers come in. 80% target? in calf in 6weeks out of all your eligible cows, the 90% figure is out of everything in calf at start of calving.Thought we were aiming for 80% incalf with in six weeks, so never quite understood how the 90% to calf in six week unless you induced (which nobody does) or use short gestation bulls which we have but don't think I could gain 10% though, so any thing above 80% is top operator
100 cows start of mating, 80 in calf in 6 weeks, 15 over the next 5 weeks, 5 mt. cull another 10% for mastitis, lame,deaths etc so at start of calving you have 72 cows due in 6 weeks plus 18 of your 20 in calf heifers (90%of them got in calf in 6 weeks)= 90 calvings from 100 animals
Doable as some people may get 85% and 95% in calf in 6 weeks but pretty good going if you can do that every year I’d say
