Likewise, people ask, Should you keep a heifers first calf?
Time quickly gets away when you're a cow-calf operator, but it's essential to keep the first calf heifers on track. Heifers conceiving early in their first breeding season will have increased lifetime production and efficiency.
Herein, When should heifers first calf?. 1. Age at Puberty. Heifers should reach puberty from 1 to 3 mo before the average age that heifers are to be bred. For example, in order for heifers to be bred as yearlings and to calve at 2 yr of age, they should have reached puberty by 12 to 14 mo of age.
Similarly one may ask, What do you do with heifer calves?
- Keep and expose cows to rebreeding for spring calving in 2020.
- Put weight on and sell as cull cows later this spring or summer.
- Sell cows immediately and replace immediately with a cow-calf pair or wait to replace in the fall with a bred heifer/cow.
What is a 1st calf heifer?
Hopefully, first-calf heifers are the first females to start calving on the ranch. ... Breeding heifers to calve before mature cows then allows them closer to 100 days to resume estrous cycles and sets them up with better chances of rebreeding with their second calf early in the breeding season.
Supplement first-calf heifers with grains (energy) like corn, corn silage, or barley before they lose body condition. “Thin heifers don't breed back quickly, if at all,” says Bjurstrom. “If she rebreeds late, it will take several lactations to get her back on track with the rest of the herd.
A first-calf heifer at peak lactation is going to require at least 58 percent total digestible nutrients (TDN) and 9.3 percent crude protein (CP) in her diet just to maintain what she has. If she needs to gain some weight before breeding, she will probably need at least a 65 percent TDN and 12.1 percent CP diet.
Animal behaviorists have found that they interact in socially complex ways, developing friendships over time and sometimes holding grudges against other cows who treat them badly. These gentle giants mourn the deaths of and even separation from those they love, sometimes shedding tears over their loss.
Absence of the vital signs, sloughing of the hair or foul odors may indicate the calf is dead.
The calves will remain by their mothers' sides until about eight months of age. Then they will be weaned and sold somewhere from October to December.
The breeding ability of bulls usually is at its peak about 36 months of age, and it declines after 5 or 6 years of age. An extra calf crop can be sired by using bulls as yearlings. However, if you're a new owner, it's to your advantage to grow out young bulls in a satisfac- tory manner.
Usually it's best to wait until they are at least 15 months of age before breeding. Even though the early maturing breeds do reach puberty by the time they are around 7 to 9 months of age, it is best to wait until they are around 13 to 15 months of age before you can breed them.
It takes at least 30 days after calving for a cow's reproductive tract to return to normal. Therefore, some cows can be bred starting 45-60 days after calving. Your veterinarian should palpate the reproductive tract of each cow as soon after 30 days after calving as possible to make sure the cow is ready to breed.
"Sometimes smearing the birth fluid across her muzzle and tongue, and then onto the calf, will stimulate her normal response," says Arnold. "Using a strong-smelling compound on the calf and in the cow's nose has always been a very popular method, using something like Vick's Vaporub, or hairspray, or vanilla."
After weaning, the amount of shrink in one day amounted to 3.5 and 3.9%, similar to the amount of shrink after 8-hours of standing in a drylot. Calves did not regain their off-pasture weaning weight until 14 days later.
The calf can live for about 8 to 10 hours in the uterus after the beginning of true labor (rupture of first water bag). Actual expulsion of the calf takes 1 to 4 hours in a cow and 2 to 6 hours in a heifer.
And although calf fetal movement is better at 7 months, but it is really only at 8 months that you can really see the calf moving around in the womb. ...
