GRAZE: A Beef-Forage Model of Selective Grazing

Published in Robert M. Peart, R. Bruce Curry, Agricultural Systems Modeling and Simulation, 2018

Dry matter refers to material that does not contain any water. In terms of the animal, water may be viewed as an essential component of the body. However, water contains no energy that can be used to convert animal feed dry matter into another form nor is any energy derived directly from water when it is lost from the tissue of the animal body. In GRAZE, it is assumed that water is always available to the animal.

At the end of the fermentation process, the residual solid part of the carob waste was recovered and weighed. A portion was dried to quantify dry matter. The determination of residual sugar in the waste was carried out as follows: the waste was dried at 70 °C for 24 h in an oven and ground into powder. A solution was prepared by adding 50 mL of distilled water to 0.7 g of powder. The mixture was centrifuged and the supernatant recovered for total sugar determination by the method of [17]. Similarly, the digestate was subjected to the same method for the determination of residual sugar in the liquid phase. The sum of the amounts of sugar remaining in the digestate and the solid waste represent the total amount of residual sugar.
