The biochemistry of growth for domesticated mammals may be similar in different species. A new mathematical method to predict protein and fat retention regardless of species was proposed. The inter-species relationships between protein and fat weights and body weight were studied in four domestic species (cattle, pigs, sheep and goats) using data collected from early age to maturity. The results indicated that retention energy for fat deposit with degree of maturity can be represented in terms of a general Michaelis-Menten type equation, and protein and fat retentions could be predicted using this equation. The equation may also permit inter-species comparisons for body composition at the same degree of maturity.
