That's kinda what I'm seeing from the limos crosses I have.. they milk very well right from the start but the mommas look like a can of smashed arseholes by the end of the season.. so far they've bred back alright though
I ran some high percentage ranch type Hereford heifers in a previous life. Excellent breed back, but had to watch the calves for BRD. I think limited milk stressed them and increased the chance of disease.

I have been calving heifers a couple weeks early, so if they have their second calf at 45 days from the cow herd start, they are really at 60 to 70 days back from their initial calving date. The place I see the most rebred delay is on slower maturing heifers that continue to grow a lot after calving. Some breed tendencies here. :cowboy:

I had on old timer tell me to calve heifers later than the cows. :???: His theory was to rebred them before they got milked down. Could be some feed quality issues involved in his operation.

I think it depends on your management, but I've often found the later calving ones breed back better as well.. If you grain your animals I think it's different

I have little no experience on this but we are also a small farm. My smallest cow has shown progressively better calves each time (now on her 3rd). Her first calf was 55lbs, second 60lbs and yesterday gave birth to a 75lb calf.

I bred 5 heifers this year. 4 have calved so far and they have all actually given me similar calves to their size at birth. One of my heifers was 110lbs at birth and she just gave us a 100lb bull calf. She was a big calf and she has given us a very big calf.

I can relate to the small cow herd and wanting to get the most out of it and we keep our breeding cows based on their nature mainly. If they breed easy, calve easy and are good mothers i keep them even if they give us a 50lb calf that stays on the smaller side.

Ya.
I separated my "improved" first calvers this year and gave them some oats every other day till they were on grass. One local grazier targets the start of calving for 3 weeks after turn out.

Seems people as well as animals produce at a level that is proportionate to the amount of energy available. When we are in a negative energy balance we usually prefer to lay around and do nothing. Animals are the same way. Provided with adequate energy we become productive and accomplish things in a timely and often exceptional manner.

the cows own BW is more significant in predicting the offspring's BW than the sire. She is the factory and environment. Especially if she was born/raised on your farm. The sire's BW is so important, because he is putting influence on ALL the calves.

if only my cows had a 3 week gestation! :P

I'm not sure I'd like to start calving in mid May.. yeah, no mud and longer days would be nice, but you really quickly get into heat stress in the calves around here.. We've had 100F in the shade in mid May, and some years it didn't let up til September... If the calves don't know how to drink water and find shade (or move when the shade moves off), they dehydrate really quickly
