Mastergen launch 2 New Bulls at the UK Dairy Day.


Rapidly growing bull semen supplier Mastergen, will expand their already impressive product offering by adding two new sires at this year’s UK Dairy Day.



Bestday storms in to the top 20 UK PLI rankings with £729, and is also the 6th highest sire in Germany with an impressive +160 RZG.

Bestday will boost milk solids with +70.9 kg’s combined Fat & Protein and will keep the tank full with a mighty +914 kg of A2A2 Milk! Alongside his superior production and Udder traits, he has the ability to transmit healthy, durable daughters with strength and superb locomotion.

Bestday really is one of the most exciting sires on the market, a direct descendant of the US family of Wilcoxview Rudi Cali EX92 (Bestday’s 4th Dam – All-American in 1999 and won her Class at the World Dairy Expo 1999). Bestday is backed by an impeccable 14 generations of VG/EX Dams from a deep All-American cow family. His Grand Dam’s half-sister is renowned brood cow Norgard XY Ting Bookem Camil VG85 who is now owned by high profile breeders – Colonia Holsteins in Germany.

His unique pedigree of Bestboss x Balisto x Emerald makes him a favourable outcross sire at the top of the index rankings!

Go-Farm Inseme SPRITE

Go-Farm Inseme Sprite, with £697 PLI, positions himself in the UK’s top 30. He is also a chart topper in Italy where he scores +3977 gPFT ranking him 2nd.

He is the only bull in this category to transmit +2 points of Type, plus on Chest Width (+0.50) and a whopping +0.18% Fat.

Sprite hails from a high demand Italian pedigree and is an early son from Afterburner. His unusual sire stack of Afterburner x Speaker x Uno makes him a fresh bull for breeders looking for different bloodlines without having to compromise on key traits.

With 5 generations of VG/EX Dams his exceptional maternal line has already proven itself in the breeding world. His 3rd Dam, Pirolo Goldwyn Schady is a full sister to popular proven sire Wyman.

Sprite is quite clearly a breed leader and when it comes to an elite combination of PLI, Type and Production – there is simply no other bull available in the UK to transmit the whole package, as he does!

Being a smaller stature sire with positive health traits, Sprite will suit most management systems producing durable, balanced daughters built to last.


2nd Dam: Pirolo Numero Uno Savana VG87
