Digestibility experiments were carried out with dairy heifers to
determine the digestibility of orchard grass, Dactylis glomerata, and
also to evaluate the accuracy of various indicator techniques in pasture
digestibility experiments. Chromic oxide was used as an external
indicator to predict fecal dry matter output in three digestion
trials. Cut...
The object of this study was to analyze the application of linear
programming techniques to ration formulation for feedlot lambs and
steers.
Three rations for feeder lambs were designed to study the application of linear programming techniques under varying ration constraints.
Rations studied were as follows:
iso-caloric rations with
three...
