Does anyone use timed breeding? We've done it for the last 3 years( gnrh, cidr, lute than gnrh at time of AIing, I think heifers at 54 hours and cows at 60. We didn't heat check at all, this year we hit 80% on the cows but heifers are at 50%. Typically we have been 60-70% on the cows, this year was exceptional. This year we are going to MGA on the heifers and heat detect for a couple days. They are on free choice sorghum-sudan baylage with 4#/day of 1/3 soymeal 2/3 cracked corn. Replacements look good, gaining around 1.5-2#/day, alittle condition but not fat.
We've never done real good on heifer conception on the AIing. What am I missing? anybody got suggestions? 3 years of the timed breeding on the heifers and I just not happy with the results.
