[QUOTE="Son of Butch, post: 1153201, member: 14585"] A good beef cow raises and weans a calf while maintaining a 12 month calving interval. Her "job" is to be pregnant, calving or trying to get pregnant while feeding her calf. revenue lost + cost of maintenance = total $ lost Let's look at a 13 month calving interval vs 12 month 1 month is 8.34% of a year. so a 13 month calving interval would = 8.34% loss of revenue vs 12 month IF your weaned calf average price is $1000 1000 x 8.34% = $83.40 lost revenue [1000 - 83 = $917] feed is by far the biggest expense in cost of maintenance cost of feed per cow per day x 30 extra days of carrying an open cow What number do you want to plug in? I'll use $1 per day to keep the math simple. 1 x 30 = $30 $30 + 83.40 = 113.40 divided by 30 days = $3.78 lost per day open after 12 month calving interval i would round to $4 per day to keep it simple and to cover the time value of money plus all other misc expenses. On plus side there would be an opportunity to increase revenue by $27.80 per cow by shortening her calving cycle by 10 days. 83.4 divided by 30 = 2.78 per day 10 days x 2.78 = 27.80 21 days x 2.78 = 58.38 My math says a cow that settles on 1st service vs 2nd service is $58.38 more profitable and 1st service conception vs 3rd service would be $116.76 [/QUOTE]
