Artificial Insemination is the second most common practice of breeding livestock, and it's the only alternative to natural breeding.Artificial intelligence is more common in dairy production than it is in beef production.In order to achieve a high success rate in cattle breeding herds, you need to know how to use artificial intelligence.There is an article about what is involved in artificial intelligence.If you want to gain certification for being able to use artificial intelligence in livestock, you need to visit a bull semen dispersal company.If you have not yet got a bull to help you breed, you should check to see if they host any programs that teach you about artificial insemination.Please consider using an experienced certified artificial intelligence tech for your cows.It's better to use these people than it is to train them to do it.
Step 1: Look for signs of estrus in your cows and heifers.
Females go into heat once every 21 days, and the heat lasts for 24 hours.There is an article about how to tell if a cow is in Estrus.The majority of heat periods start at dusk or dawn.
Step 2: It's when females should be AI'd after 12 hours after estrus.
This time period is when the female ovulates, sending an ovaum out to the fallopian tube to await fertilization from a bull.
Step 3: If proper handling practices are followed, you can put the heifers or cows in to the alley and catch the first female in the head gate.
If there are other people behind her, make sure they are behind another gate so you don't get hurt when they try to move up.If you have a squeeze chute with a palpation cage attached to it, you can use it to do your artificial intelligence.Each cow is lined up beside one another in a stanchion in some of the barns.It's convenient for the tech who has to work on over 50 cows in a day.It is best to do artificial intelligence outside on sunny warm days, not when the weather is rainy or windy.If you set up a facility inside a shed or barn, it will be much better.
Step 4: The temperature of the water bath should be between 90 to 95 degrees.
It's a good idea to use a thermometer for better accuracy.
Step 5: The canister you need has semen in it.
There is a semen inventory on the tank that keeps track of the location of each bull.
Step 6: The canister should be removed from the storage location to the center of the tank.
To grasp the cane of semen, lift the canister just high enough into the neck region of the tank.The frost line should be at least two to three inches from the top of the tank.
Step 7: Lower the canister to the tank floor if you want.
The cane should be kept as low inside the tank as possible.
Step 8: Nitrogen goes into a gaseous state when exposed to air and warmer temperatures, so Shake the straw to remove excess liquid nitrogen.
Step 9: Place it in the thermos for 40 to 45 seconds.
The water should be warm enough to thaw the semen straws.
Step 10: After the straw is put in to the warm water, put the can back in the canister and return it to its storage position.
When it takes over 10 seconds to locate a cane, the canister must be lowered back into the tank.When you remove the semen from the cane, never return it to the tank.
Step 11: Before you prep the thermos with warm water, you should have your gun pre-assembled.
Warm the "business end" of the gun up in your coveralls close to your body if it's cold outside.Rub a paper towel on the rod to warm it up.It's best to keep it in a cool place.The gun should be cold to the touch.
Step 12: Remove the straw from the thermos and wipe it dry.
Before you do anything else with it, it should be completely dry.To adjust the air bubble in the straw, hold the crimped end to your wrist.The bubble should be moved by the flick.
Step 13: The straw should be placed in the rod.
The clip is from the crimped end of the straw.Use sharp scissors or specially designed straw-cutter scissors, and cut in the area that the air bubble is located.
Step 14: To transport the gun to the cow and to maintain a constant temperature, wrap it in a clean dry paper towel or protective sheath and tuck it into your clothing close to your body.
Step 15: If you tie up the tail on your left arm, it won't interfere with the process.
To clean out any feces that may interfere with the process of feeling for the gun, gently reach inside the cow with one hand, and the other should be gloved and lubricated.
Step 16: The vulva can be cleaned with a paper towel or rag.
Step 17: Take the gun out of your jacket or overalls and put it in the cow's vagina at a 30 degree angle.
This will prevent you from going into the urethral.
Step 18: With your left hand in the cow's rectum, feel your fingers through the wall of the vagina until you reach the cervix.
Step 19: If you want to thread the rod into the cow's cervix, you need to grasp it with the hand in the rectum.
Step 20: The location of the rod should be checked with your index finger.
The rod should be less than an inch into the uterus.
Step 21: At the end of the plunger, depress it so that your right hand is deposited.
Step 22: Make sure you are in the cow's uterus and not in any of her blind spots by checking the location of the semen.
Step 23: The gun, hand and arm are inside the cow.
Blood, infections, and semen "feedback" can be found inside the sheath.
Step 24: You can check the straw to see if you used the right bull semen.
Step 25: The towel, glove, and straw should be thrown in the trash.
Step 26: If it's necessary, clean the gun.
Step 27: You can keep record breeding information on your record keeping system.
Step 28: If necessary, release the cow and restrain the next one to be inseminated.
Step 29: Before repeating the steps above for another cow, you need to check the temperature of the water in the thermos.
Step 30: The next cow should be followed by the steps above.
