Getting 75% heifer calves this spring. Is this a sign I need to retain more ?
Only if they are born in the first cycle of the calving period, otherwise no.Getting 75% heifer calves this spring. Is this a sign I need to retain more ?
Is this based on an assumption that fertility is highly inherited?Only if they are born in the first cycle of the calving period, otherwise no.
So? The younger calves will weigh less (on average) which equates to less lbs of beef per unit of land per cow.A lot of my better performing older cows were born in the second cycle.
Your reading compression is still lacking I see.So? The younger calves will weigh less (on average) which equates to less lbs of beef per unit of land per cow.
Are you going to tell us you keep heifers born in the second cycle from cows born in the second cycle? Oh Canada!
I don't choose cows by the size of their udder, I choose them for longevity and how many pounds of calf they wean. I've seen tiny udders wean huge calves and big bags wean undersized calves. Biggest calf I ever weaned was off a first calf heifer with an udder so small it was hard to see.I've seen it both ways. The biggest heifers in the fall, aren't always the best replacement heifers.
Neighbors always kept ALL their heifer calves and calved them out. The fall of their 2 year old year, when they have a calf following them, is when they picked their replacements. That worked really well, but not many can do that. I do think the longer you can wait, the better. Our neighbor said it usually worked out that some they would not have kept as calves, were the better heifer and vice-versa.
A good cowman told us when selecting heifer calves in the fall, get them in an alley with someone watching from the rear and someone watching from the front, and observe the way they travel and especially their udder. Even at that age, you should be able to see some folds where their udder would be. Of course, that was before milk epds...but it sure seemed to help for us to do that. We like to pick heifers that are more wedge-shaped (you have to be careful that they aren't pinched in the front, they can be too wedge shaped) and try to never pick a heifer that is bigger in the front end. It's just not a feminine trait.
Whatever your method for selecting replacements, be highly selective. I would not save replacements from the two heifers you mentioned!Have two heifers that calved so far this spring. One is the same - - calf tries to nurse and she kicks or shakes it off the teat. Calf then ends up sucking on the Bitch's belly.
mine too SilverA lot of my better performing older cows were born in the second cycle.
The way I see it is that if a retained heifer is 3 to 4 weeks younger than your oldest retained heifer but breeds to calve in the first cycle then I know she is at least as fertile as the older heifers.@Rancher and @Silver, does the colder calving and milder grazing climate where you live have anything to do with better performing 2nd cycle cows - and heifers? Just curious. I have retained late calvers in the past, based primarily on emotion (but I love her!!!), and some of them have caught up and fit in with my 45-day goal (which ain't gonna happen this year). But more often than not, she remains late or all over the place.
That said, there's clearly no guarantee. I've retained all the heifers from one of my fave cows (and her 2nd granddaughter) and they've all calved early, raised very nice calves and bred back right away. Until this year. Her 5th heifer just had her first calf earlier this week - way after the other heifers calved and just over 2 months from the start of calving. She's a great first time mama and hopefully she'll catch up, but gotta be honest, I'm a little disappointed. I saw the bull supposedly breed her 2 other times before she finally settled.
