    Hey Folks,

    I weighed my stores the other day and the five best heifers are from 485kgs up to 510kgs.
    I'm going to start these five on meal on Monday building up to 4 kgs per head per day, they'll get this for 6 weeks= 4x7x6= 168kgs.
    They'll also have the prime grass with the rest of the stores grazing behind them.
    What sort of weight gain could I expect from the heifers over this time?
    I.E. what weight will they be when i live weigh them again in 6 weeks time?

    Assuming 40kg weight at birth:
    1.1 kgs for the 2 home reared sucklers
    0.9 kgs for the three bought in dairy bred angus

    Cheers Stirrer, i'd forgotten all about that thread, I must dig out the factory docket from last year, I fed them the meal for the 6 weeks at 4 kgs per day.
    I only got the scales this year so I'll be very interested to see how they weight at the end of the feeding period and also what % they kill out at, i always assume a 52% killout for heifers and 55% for bullocks.

    Just after checking out the killout last year:
    The 8 killed in September averaged 507kgs live weight @ 15 months and made on average €977: 264kgs deadweight @ €3.72 per kg

    why slaughter at such a light weight, were they small AA or what?
    anything from a 1kg to 1.7kgs lwg depending on the animal. over this gain for a heifer would be unusual

    Thats around 52%. I finished angus heifers off a grass only diet a few years ago and they killed out nearer 60%.

    that's one high grass killout

    They are AA and born in June/July and are killed in September the following year, it's a quick turnaround system killing them at 15 months, cheaper than wintering them a second time.
    I held onto the lighter heifers until May and they killed out at 595kgs liveweight and made €1,259: 309kgs deadweight @ €4.06 per kg

    I didn't have their liveweight, i assumed a killout of 52% and worked it back from their killout weight to find their liveweight, now i've a scales i'll know exactly the killout %...
