The 50 heifers gained 0.86 kilos of carcass for each day they were on-test at Tully and had an average carcass weight of 301kg. 30 were of R grade conformation and 16 fell into the O grade class.

Ireland’s progeny testing programme - which is carried out by ICBF (Irish Cattle Breeding Federation) at Tully, Co. Kildare - recently slaughtered 50 Dairy-Beef heifers at Slaney Foods International - Bunclody, Co. Wexford.

The group consisted of 50 February & March-2017-born heifers (19-21-months-old) with 16 different sires across 4 different breeds including Angus; Hereford; Shorthorn and Limousin.

Performance

The average daily gain for the group during their 59-day performance test period was 1.68 kilos/head/day, which led to an average carcass weight of 301 kilos, according to the ICBF.

Average growth rate within the group ranged from 1.14 kilos to 2.34 kilos/head/day, with an average initial live-weight at 492kgs and a live-weight of 590kgs recorded.

4 of the heifers graded Us; 30 of the heifers were of R grade conformation and 16 fell into the O grade class, according to the ICBF. Meanwhile, the average kill-out for the group was 51%, with kill-out ranging from 47% to 54%.

The average dry matter intake (DMI) per day for the group was 12.2 kilos, with heifers consuming from 9.7 to 15.1 kilos/head/day on a DMI basis; the average feed efficiency for the group was 6.63, ranging from 5.1 to 10.5.

The entire group was scanned for Pre-Slaughter Muscular Depth (mm); Pre-Slaughter Fat Depth (mm) and Pre-Slaughter Intramuscular Fat, the ICBF highlighted.

"Performed exceptionally well for their age"

The 50 heifers were fed a TMR consisting of hay; water and meal over their 59-day finishing period.

"Overall, the heifers performed exceptionally well for their age and were gaining 0.86 kilos of carcass for each day they were on test at Tully." The ICBF outlined in a statement.

"The data demonstrates the large variation in performance between dairy beef progeny in a finishing system." The ICBF concluded.
