Select Reproductive Solutions (SRS)


Heat Detection and Artificial Insemination

Heat detection is often cited as the most costly component and undoubtedly, the major limiting factor to the success of A.I. programs on many dairy farms. Incorrect detection of estrus is related to loss of income due to extended calving intervals, milk loss, more veterinary and heifer rearing costs and slowed genetic progress. While heat detection can be a major problem for some operations, getting a female pregnant after a detected heat is just as important.

Proper knowledge of the anatomy and physiology of a dairy cow is the first step in correct heat detection and artificial insemination. Next, a technician must have experience with the techniques necessary for accurate heat detection and artificial insemination.

"After being in a new barn for a year or so we were having trouble keeping our pregnancy rate up with tail-chalking and reverted back to some of our previous techniques of heat detection. One of my old herdsmen sent Brett Mackay from Select Sires to us to talk about Reproductive Solutions. Brett went through our breeding program and helped my current herdsman with the tail-chalking techniques and our breeding program. We are very happy with the results that we are getting since Brett has helped us!"
