১০০%সফল কৃত্রিম প্রজনন |100% sure artificial insemination. Review the reproductive anatomy of the cow, heat detection, semen handling and the process to breed the cow to prevent common mistakes.
‎First-time conception rate in virgin heifers should be 55% or more.
‎For lactating cows, the goal should be a conception rate of 40% or more.
‎Semen should be thawed at 95°F for 45 seconds.
‎Use your left hand in the rectum and right hand to guide the insemination gun regardless of your dominant hand.
‎Slowly deposit semen - it should take about 5 seconds.
‎After breeding is complete, re-check that the desired bull was used for the mating.
‎Herd breeding goals
‎In virgin heifers, a reasonable goal is a first-time conception rate of 55% or more, or fewer than 1.8 services per conception.
‎
‎For lactating cows, the goal should be a conception rate of 40% or more, or fewer than 2.5 services per conception.
‎
‎Getting the cow ready
‎First and foremost, the cow must be ready to be bred. This can be determined by noting signs of estrus or based off a timed synchronization program.
‎
‎Properly restrain the cow when it is time to breed; it is important for both the cow’s and inseminator’s safety. Pick a place that is easy to use and is familiar to the cow to reduce the stress of the situation.
‎
‎Proper semen handling
‎Store insemination supplies and semen tanks in a clean and dry location at all times. Keep accurate records as to semen location within the semen tank and the number of units available.
‎Breeding the cow
‎It is recommended to use your left hand in the rectum and right hand to guide the insemination gun regardless of your dominant hand. Use a new breeding glove for every insemination.
‎
‎Lubricate the glove with mineral oil or a commercial A.I. lubricant.
‎Let the cow know that you are there by gently patting her on the rump or talking in a soft voice. Enter the rectum by forming a cone like shape with your fingers. Gently palpate the cow and remove any excess manure.
‎Place the tail on the back side of your left arm so that it is not in the way during insemination.
