Cattle Reproduction

Cows typically give birth once a year. The gestation period for a cow is around nine months, so they will usually have one calf per year.

Bull calves. When they are weaned and/or reach around 10 months of age they are referred to as bulls or young bulls.

This could be a number of things, the calf could have a pinched nerve, could have broken hips (result of mother accidentally stepping on it), the best way to discover what the problem is, call your veterinarian, they will be able to view the calf and diagnose the problem.

I hope that this is a help.

The biggest concern for a first-time birth is if the cow can actually have the calf unassited. It's best if you can keep her restrained to an to a small area or a pen where she can be frequently monitored when you think she is close to having the calf. When she actually goes in to labor, watch carefully to see if she needs help, and call a vet if needed. If the birth is successful, make sure the calf is able to nurse her and is healthy before letting them out.

Bull semen is the liquid that is developed from the prostrate, cowpers, bulbourethral and vesicular gland to provide a nutrient source and means of locomotion for sperm when travelling down the cow's reproductive tract on their way to fertilize the ovum upon being ejaculated via the penis unto the cow's vagina.

Try reinforcing the calf's joints with self-adhesive bandaging (like that used to wrap horses legs). Wrap the joint tightly (although not tight enough to cut off circulation) and wrap it heavily enough to stabilize the joints. If you have any old cardboard tubes from toilet tissue or paper towels, cut them open the long way and put them over the joints before wrapping. Sounds odd but it works! Help the calf walk to build up its strength.

It would look like a cruel joke that someone played on a quality working dog, I imagine it would be small hideous and feeble, with prick ears and long hair, and a tiny penis incapable of passing urine. The type of dog cast aside in dumpsters across the nation.

It is important that you do not over work the bull, usually in a period of 8 hours about 3-5 is a good number for older bulls.

For a better understanding, the ideal bull to cow ratio would be for yearling bulls 15-20 cows. 2 year old bulls 20-30 cows; and for 3 year old or older 30-40. This ratio is usually for pasture breeding, when the cows and bull are turned out for the summer months when the bull will then breed them as they cycle.

It's the end of the breeding season. Breeding seasons on any farm are normally 60 to 80 days long (the shorter the better since cows that do not get bred are deemed as cull cows because of their lower fertility rate), and in order to keep track and improve the fertility of the cow herd, the herd bull must be removed after a certain period of time.

If given a choice of where to go, most cows are really good about not doing this. They will find a secluded and clean spot to give birth on, away from the usual feeding and defecating areas other cows would be found. However, if they are confined to a feedlot or in an area where a producer has failed to clean out the area the cow is to calve (which doesn't happen all that often) a cow may have no choice but to do so.

This all depends on the producer. Some like to castrate a bull calf when they're barely a few days old because this immediately inhibits the bull calf's testosterone production, and also prevents any accidental breeding if the herd is particularly fertile. Castrating early is also much less stressful and less painful for the calf than if it were done later.

However, other producers like to wait to castrate their bull calves to take advantage of the added growth potential that bulls have over steers, and consequently make for higher weaning weights (and more profit) when they're sold later on after being backgrounded. But, castrating later can make it more stressful for the weaner bull-turned-steer calf because of not only the stress of being separated from his mother, but also the pain that he experiences, making him eat less and gain less during this period, making him more susceptible to illnesses like pneumonia or shipping fever.

The young female of a cow is called a heifer. A heifer is a female bovine that has not yet given birth to a calf.

It should be done as soon as conveniently possible, but as long as the testicles don't become too large for the band or the bull isn't too strong to fight you off (depending on you're method of banding), any time is fine. The only difference is the amount of time the steer would have to grow differently.

They can if they want to, but it won't make a human pregnant though.

Cows lick their calves to clean them and help stimulate their circulation and breathing. It also helps establish a bond between the cow and her calf, and the licking helps the calf recognize its mother through her scent and taste.

Average weight would be around 600 lbs, depending on the breed.

British beef calves tend to be around ~500 to 600 lbs (226 to 270 kgs) at 6 months of age, whereas the Continentals and Brahman-type breeds weigh in at ~650 to 750 lbs (295 to 340 kgs).

Dairy calves, on the other hand, tend to be a little lighter, except Holsteins and Brown Swiss. At 6 months of age, Holsteins and Brown Swiss should be around 400 lbs (~180 kgs). Jersey calves, the smallest commercial dairy breed, can weigh in at less than 375 lbs (~150 kgs) at 6 months of age.

The most tell-tale signs are that she is not progressing any after the water sac comes out. Just by looking what is coming out the vulva (or what isn't) can also be a sign that she's having trouble. If the feet are coming out upside-down (or rather, the hooves are pointing up instead of down), if only one foot is coming out, one leg appears to be too far back than the other, if there's no nose poking out between the legs when you check, if there's only a tail visible in the birth canal, or she hasn't progressed after 3 to 6 hours after the water sac emerged, then it's time to either call the vet or get her in the chute and see what's going on.

There wouldn't be any offspring. A cow cannot mate with a cow to get a calf. You must mate a cow with a BULL to get a calf.

So, if the question were reworded to: "What would the offspring be if a roan cow was crossed with a roan bull?" or vice versa, then we could answer it this way:

Roan colouration in Shorthorns is a codominant trait, which means that one allele is not dominant nor recessive over another. So, the resulting offspring of a roan cross would be a mix of red calves, white calves, and roan calves.

The Punnet Square reveals the probability of one of three coat colours occurring in the subsequent cross:

Let R = red and W = white and RW = roan.

RW bull x RW cow gives us:

1 RR

2 RW

1 WW

In other words, there's a 25% chance that the resulting calf would be red, a 50% chance that the resulting calf would be roan, and a 25% chance that the calf could be white.

An average cow will usually have one calf per pregnancy but occasionally she can have twins, and triplets very rarely.

Yes, the Collins brothers bred horses, sheep, and pigs in addition to cattle. They were known for their success in breeding and raising high-quality livestock across multiple species.

Approximately 1-2% of calves are born as twins. Twins in cattle are less common compared to other livestock species due to the limitations of uterine space and the higher nutritional demands of twin pregnancies. Twinning can present challenges for both the cows and the calves in terms of health and management.

Yes, male Holstein calves are commonly killed shortly after birth if they are not needed for breeding purposes due to the economic challenges associated with raising them for beef production. This practice is known as the veal industry, where the calves are raised for veal meat.

A cow should ideally give birth within 2-4 hours of the onset of labor. If labor surpasses this timeframe, there could be complications, such as a breach birth or the calf getting stuck, requiring veterinary assistance. It's important to monitor the cow closely during labor to ensure both her and the calf's well-being.

The birth weight of a Jersey calf typically ranges from 60 to 90 pounds. This can vary based on the individual calf and its genetics, as well as factors like nutrition and health of the mother cow. It's important to monitor the calf's weight and growth to ensure proper development.

Cows will show signs of heat cycle (they will bellow, they will mount or stand for mounting), the bull will smell that she is in heat (often the cow will urinate and the bull will smell the urine-this is referred to as the Phleaman response). They will then breed.
