Every day, and each proof round, Semex works to deliver our customers the very best newly released daughter proven sires and exciting young genomic sires available anywhere in the world. These sires are Genetics for Life, representing genetic solutions, long-lasting partnerships, profitable herds and lifelong partnerships.

Following the December 2012 genetic evaluations, Semex is pleased to release one of the most highly anticipated Ayrshire sires in the industry, 0200AY00680 Kamouraska Rockstar, as the #1 new release LPI Ayrshire sire and #2 LPI Ayrshire sire overall. 

Rockstar arrives as a HealthSmart™ sire, siring daughters that are productive and thrive. They are proven to last longer and be healthier, which means more money for the dairy. He is also a high fertility Repromax™ sire, with a proven ability to raise you herd’s reproductive performance. Rockstar is backed by four generations of brood star cows and his granddam, Kamouraska Jerry Virvana EX, is also the dam of Semex’s 0200AY00659 Kamouraska Mandarin. We also find some of the Ayrshire breed’s top bulls in his sire stack including Modem, Peterslund, Jerry, TBruno, Cornelius and Heligo.

“After inspecting many daughters, there is only one word to describe them… Uniform!” says Chris Studer, Semex Ayrshire Coordinator. “With around 50 daughters scored, he is at 72% GP+ with six VG two year olds. They are nice framed, average stature cows. He will transmit great feet & legs and mammary systems, and his daughters are milking well and breeders have commented on their high components.”

Rockstar is the total package and will work well in every dairy environment, transmitting high herd life, high conformation, high components, low somatic cell score, excellent feet & legs and quality, well-attached udders. That is Genetics for Life.
