Pre-breed Scanning and Pregnancy Scanning with the use of sex semen in first lactation cows.

Visited a pedigree Holstein breeder with a rolling herd average of 10,000 litres in 305 days where he presented a group of first lactation cows which were AI’d using sex semen in the first week of April.  In 19 first lactation cows, 10 pregnancies were diagnosed and in two of these animals, twins were diagnosed.  The farmer had the satisfaction not alone with the pregnancy rate but that there was a strong possibility of twin heifers from 2 of the pregnancies diagnosed.  All of these first lactation cows were selected on the basis of a pre-breed scan whereby animals diagnosed as reproductively sound were AI’d using sex semen.  In conclusion, pre-breed scanning of first lactation cows is an aid to achieve an acceptable pregnancy rate using sex semen in first lactation Holstein dairy cows.
