The Production Committee of the ICSA is proud to announce that Glenbrook Dainty 10 bred & owned by IL & JA Mueller of Murray Bridge South Australia has broken the Butterfat Record KG for a Junior 4 yr old Illawarra.
Calving at 48 months of age Dainty 10 produced 642 kgs of Butterfat at an average of 4.8% in the 305 day lactation.
Glenbrook Dainty 10 now attains the National J4 BF Record after surpassing the previous record held by Blackwood Park Laurel 90 with 632 kg BF set in 2014. So it`s easy to say with only 10kg of BF separating these records just how close and hard it is to break an Illawarra Production Record.
Glenbrook Dainty 10 is sired by Glenbrook General.
Congratulations to the Mueller Family.
Brian Parker
Spokesperson for the Production Committee ICSA
