Definitions:
Pregnancy Rate = Number
of cows that are pregnant at the end of the breeding season.
Conception Rate = Number
of cows pregnant to A.I. sires at the end of the breeding
season.
Drug
Cost = GnRH cost per dose + Prostaglandin cost
per dose.
Semen
Cost = Cost per straw + arm cost. This multiplied
by # cows in heat.
Labor
Cost = number of people X hourly wage X time
spent. Do this for 2 trips for injections, and AI.
Bull
Cost = Bull cost per year (purchase price Ð
salvage price, divided by #yrs used) + feed costs.
Age
Advantage.
= Postpartum days are shortened per cow by 13 days when
compared to natural breeding. 13 days X calves X ADG X $/lb.
Genetic
Advantage = A.I. sired calves can add 15 lbs
over average weaning weight. Conception rate X 100 X 15lbs
X $/lb.
2 bulls used as cleanup in AI example, 4 bulls used in bull
example.
