| This manuscript chronicles the evaluation and development of the preruminant calf as a model for the study of the absorption, transport and metabolism of ;This work has demonstrated the appropriateness of the preruminant calf model. The usefulness of the model for a given study must be determined after careful consideration of the strengths and weaknesses of the model. The hindrance of the calf's relatively great size, special needs for housing, handling and slaughter facilities and high expense must be balanced against the unique value of an animal which can easily provide multiple blood samples, will readily consume unusual foods and is large, docile and hardy enough to undergo various surgical procedures. |
