AI is a method for a dairy cow to get pregnant. She should catch (or get bred) within a day or two after being AI'd.
By getting bred by a bull or having an AI tech insert bull semen into her uterus. See the related question below for more information.
Cows can get pregnant through the process of mating with a bull, where the bull inseminates the cow. This can happen naturally through natural mating or artificially through artificial insemination by a qualified professional.
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.
Wait for 12 hours after you've last seen her estrus activity before AI'ing a heifer or cow.
Practically, yes. The AI pair has a type of long A sound, and the Y has a long E sound. But the presence of the R extends the first syllable. The AI vowel sound here is indicated by a caret A, which forms the AIR phoneme. The rhyming word "fairy" is very close in sound to "ferry" especially in British English.
First you have to get the cow bred by either a bull or by AI, then after making sure she is bred and not open (not pregnant), then you can ship her to the salebarn or auction mart to sell her off. You should only do this if you have to cull any cows that are, in some shape or form, are not worth keeping on your farm anymore.
Your cow can be bred at a local farm that has a breeding bull that can be put with her for a couple months. You can also have an AI tech come out to your farm to have your cow artificially inseminated. Costs depend on each farmer and/or AI tech. You will have to pay for the bull semen straw as well as a fee for the AI tech to do his/her job, or pay the for rent on the bull for however much he'll charge you per day.
Are you asking can a human breed a Jersey cow? The answer would be no; no offspring would be produced in such a cross. But, you can breed a Jersey cow via AI or artificial insemination with semen from a Jersey bull.
When she shows her first signs of heat, you have to AI her 12 hours later. The process of AI-ing only takes a couple minutes, or even shorter if you're really good at it. As for the natural process, the act of copulation between a bull and a cow only takes a few seconds.
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.
I assume you are referring to artificial insemination. Usually a cow will come up open after being AI'd because she wasn't bred properly (i.e., the semen went into one of the blind pockets in the cervix, or the semen was deposited too far into the uterus). AI is harder than it seems, so it takes both an expert and lots of practice to get it right.
Depends on the cow. For commercial dairy cows, that use artificial insemination, they will have a calf every year or so and there is an 85% chance that it is a heifer and not a bull. This is because bull calves only go for veal, and the heifer will eventually be bred to produce milk. For commercial beef cows, they still often use AI but it's more of a 50/50 because a steer will weigh more than a cow and ideally be worth more when it is time to sell it.
