    No we didn't enter the bdgs, probably should have though. I was looking at an article there and it said that in the USA 80 per cent of the entire population of cattle are 8 to 10 percent inbred. That's some amount of cattle
    suppose if they'r not too close it doesn't really matter

    Line breeding is where a certain sire or dam appears on both sides of the pedigree. Very effective way of ensuring the continuation of a certain trait in the line.
    In breeding is mother-son, father daughter etc. Excellent way of ‘refining’ the traits that you’re after. Downside is you’re also refining any bad/undesirable traits and concentrating them. Inbreeding can also bring out any temperamental issues.

    Would breeding a heifer to her grandsure be considered line breeding or in breeding?

    If it works, it's line breeding.


    If it doesn't, it's inbreeding.

    You'd be amazed at the amount of inbreeding there is in cattle. A limousin bull sold recently for big money in the UK. He had the bull Vantastic appear twice in his immediate breeding.

    Can't find the article now, but it was a high profile sale over in Carlisle. Vantastic featured twice within 3 generations I think. He was the Sire and also the Grandsire of the Dam, I think.

    Ampertaine Majestic was the bull's name. He sold for 35,000gns sterling.
    Here's his breeding. So 1/4 plus 1/8 of his breeding would be Vantastic.

    Just looked at Tiger Roll's pedigree there (Grand national winner today). Northern Dancer appears 4 times in his back breeding. :rolleyes:

    They say if you keep it below %75 it's ok. You can mate a half brother to a half sister, or you can introduce the same bull again 3 generations down the line. Bit strange, I haven't done it yet but probably will in the near future with a few pedigrees. You can bring out the best of breeding and a very nice uniform group of cattle that way but you can also bring out the bad. You can also bring out the bad by breeding the normal way.

    I was very against it but after talking to a few good breeders that do it and listening to their take on it I'm swinging the other way. I definitely wouldn't like to make a habit of it but given the right cow and opportunity with a flush or something like that I'd do it no bother now.

    What you're describing is line breeding or inbreeding.
    The only difference is whether the good or the bad comes out.

    Line breeding = Fantastic cattle

    In breeding = Cattle with every fault known and unknown within the line.

    As with all breeding decisions there's risk involved but that's something for each breeder to determine.
