[QUOTE="M-J-G, post: 3656230, member: 1819"] In a like for like basis the larger population gives more data and thus better indicator, of course it does that's what system is about, processing the data provided. This is not always in keeping with larger breeders though, a small breeder can still be part of a large population through genetic links, and can be better referenced than a larger isolated one. If you are being told otherwise by a technical advisor from signet I suggest that he's not the individual to seek advice from. It shouldn't be down to pedigree breeders alone IMO, as it's like putting bank robbers in charge of a safe, plus most pedigree systems are not what this type of system is designed for, it's for vast volumes of commercial data, not exclusively from non commercially run perdigee populations, recording breeders is obviously required, but it needs to be validated against actual slaughter and economical data. This in turn would help the small breeders as it would validate their tup's genetic ability in a working class situation against those from other breeds and other breeders, although it might upset a few if a favoured sheep doesn't perform well :). But EBVs aren't for the sellers benefit, they are there for the buyer. But to get back to your original point about the EBV system being [I]Prejudice[/I] about small breeders, this isn't entirely accurate, it just tends to work better with larger populations, but they don't all have to be under the same large breeder, they can be made up of well linked smaller breeders.
