It's just like knowing when to put the bull out with the cows: When they're not pregnant and are ready to be bred. Most often it will be the cow herself that will tell you when she is ready to be bred, but you have to judge when the right time would be to AI her. Ideally 45 to 60 days after calving is when you should consider getting her bred. AI needs to be performed 12 hours after her first signs of heat.
In a way, but technically, no. However, she does have to be in heat in order to know when the proper time is to get her artificially inseminated (AI). The best time to AI her is 24 hours after she has shown signs of heat or estrus. If you try to get her bred much later during the time when she's not in heat, then you won't get her bred. She must be bred when she starts to ovulate, which is pretty well 24 hours after she was in heat.
In the same frame time as for a cow that is being naturally bred: between 45 and 80 days after parturition.
A cow (or heifer) should be AI'd 12 hours after the first signs of estrus.
This is a rhetorical question: the right time to breed a cow is when she's in heat. However, AI shouldn't be performed until 12 hours after you see the first signs of estrus (heat).
Put her with a bull or get her artificially inseminated.
Provided this is a dairy cow you are referring to, and the calf has been taken away and fed milk replacer, the optimum length of time a cow can be "artificially stimulated" to produce milk is 10 months.
Not necessarily. Cows produce milk to feed their calf. They're artificially inseminated to make them pregnant, and thus they produce the milk upto, and after the birth. Whatever food they eat - whether that's naturally-grown grass, or artificially produced feeds - gives them the energy, vitamins and minerals they need to produce the milk.
The embryo is formed when the sperm from a bull attaches itself to the egg or ovum of the cow. The embryo is formed not only from the cow being bred naturally, but also when she is artificially inseminated.
The gestation for a cow that's been AI'd would have the same gestation period as a cow that has been naturally bred: around 285 days, plus or minus. Artificial Insemination does NOT affect the length of gestation of a cow, it only affects what her offspring is going to be.
A lesbian can be artificially inseminated with sperm from a chosen sperm donor.
There is a fully detailed article that answers this question in full which can be read in the related link below. Basically, though, a cow is artificially inseminated by a person having one arm up the cow's rectum to hold the cervix through the colon wall and the other arm manipulating an AI gun with a semen straw in it through that cervix into the cow's uterus. Once the tip of the gun is in the cow's uterus, semen is deposited into her. A cow can only be successfully AI'd if she was recently in heat. Otherwise she will not take nor get pregnant. Use of artificial hormones can help a producer synchronize several cow's heat cycles so that they can be AI'd all together in one day.
Most people have their English Bulldogs artificially inseminated.
A cow should be artificially inseminated (AI) an average of two to three months after giving birth, or when she starts showing signs of normal estrus which could be as late as four or even five months post-partum. Ideally it should be in the two to four month period, for a dairy cow, for her to rest (pregnancy-wise) before getting settled again.
The name of a baby cow is a Calf
There are dairy bulls. If the cow is not bred, she will not produce milk. Bulls are necessary to do this. Although, many cows are now artificially inseminated. Unless dairy heifers are needed to increase the herd or to replace cows that are too old, any bull's semen will do.
The baby is called a calf and mother is a cow. Together they are called a cow-calf pair, or "mom and baby."
