The latest update to the ICBF terminal and maternal indices have recently been released. The top five list of bulls on the maternal index is packed with what are household names at this stage, with three of them being Salers. The top five on terminal index is dominated by bulls that may not be as well-known or commonly used by a lot of farmers. While it is good to see new bulls coming through and that genetic gains are being made, it is important for farmers to carefully select which cows to mate with these newer bulls, which have somewhat lower reliability figures.
1 Gainsbarre (PT2165)
A Parthenise bull from Dovea with a terminal index of €197 and a reliability figure of 56%, he comes in at a very attractive 1.8% for cow calving difficulty. He packs a punch in terms of carcase weight, delivering +43kg. He does, however, only have six beef calving records in Ireland as of yet, but is definitely one to watch. Semen costs €12/straw.
2 Gstaad (LM4366)
Gstaad is a Limousin bull with the same terminal index figure as Gainsbarre at €197 and a reliability of 69%. Calving difficulty for cows comes in at 5.1% while he needs to be carefully considered on heifers at 10.1%. He also carries +4.2 days for gestation length, which is on the high side. He has a huge carcase weight figure of +44kg, with 75% reliability. This Eurogene bull comes at a cost of €30/straw.
3 Kilconnelly Kodaline (BB4492)
The first of two Belgian Blue bulls in the top five, Kodaline has a terminal index figure of €194 at 63% reliability.

4 Giga Du Bois Remont (RGG)
Seeming to be ever-present near the top of the terminal index list, this Belgian Blue bull has an index figure of €187, with a 90% reliability.
