摘要: Abstract This paper specifies the animal biology module of a model for simulating grazing systems ruminants on pasture. The program predicts intake energy and protein, allowing selective substitution by supplementary feeds, estimates use diet maintenance production, according to current feeding standards. Conception death rates are predicted from maturity condition animals. is designed be general application any type sheep or cattle GrazFeed discrete package that uses same procedures predicting feed productivity within tactical decision support system. help graziers assess value specified pastures need different classes
