The requirement of sheep for cobalt or for vitamin B12 [PDF]
British Journal of Nutrition, 1970 1. Sheep confined topens and given a cobalt-deficient ration which supplied about 30μgCo/d required for maintenance of normal growth rate a Co supplement approaching 40 μg administered per os daily; for maintenance of what appeared, under the conditions of the experiments described, to be the maximum vitamin B12 status of a sheep, namely 3 ng vitamin ...

Development and evaluation of a model to predict sheep nutrient requirements and feed utilisation
Italian Journal of Animal Science, 2010 A new feeding system for sheep, called MIPAF, was developed by integrating previously published equations with new ones to predict energy and protein requirements as well as feed utilization of sheep. Special emphasis was given to dairy sheep,
