    ya it was fine, in real life it would be unlikely for a ratio to come out as exactly 3:1 and if they gave a perfect ratio like 39:13 it might be a bit too obvious what you had to do with the question.

    Well to start, a maintenance ration is enough feed to keep an animal healthy and alive, it doesn't gain or lose weight or condition. A production ration is maintenance ration plus extra feed enough to product milk, meat, or wool or whatever it is you want from your animal.

    A suckler cow will need to be fed extra ration during pregnancy (production) for her unborn calf and after pregnancy to produce milk for the calf as it suckles her, after the calf is eventually weaned she will be back on maintenance ration.

    is it true that some farmers decrease the feed to cows in the later stages of pregnancy to have them 'fitter' for birth - leading to easier calving?

    yes, overfeeding can lead to them putting on too much weight which will make calving harder, so feed can be reduced a little, essentially what you want is that there is enough feed to allow the calf to grow and develop and also to maintain the cow, she doesn't really need to put on weight, a lot of it would go to fat at that stage rather than muscle.

    Just looked at the exampaper there, its a shame that nothing at all came up on pigs.. A vital sector to the economy and then info in the ag.science book is completely outdated:mad:

    Syllabus hasn't changed since 1969 and from what I understand publishers aren't all that interested in producing an ag science book because it's a minority subject. i.e. no profit. So the main book that is used is 20 years old.

    Pigs was on ordinary level though.
