This program calculates energy and protein, calcium and phosphorus requirements and predicts intake of goats. The calculation of protein and energy requirements are based on the set of equations published by the E (Kika) de la Garza American Institute for Goat Research (Langston University, Oklahoma, USA) in Small Ruminant Research volume 53, number 3, published in 2004. In addition, these energy and protein requirement expressions are those recommended for goats by NRC (2007; Nutrient Requirements of Small Ruminants. National Academy Press. Washington, DC), as well as are the Ca and P requirement calculations.
