title: Indian research on protein and energy requirements of goats.
abstract: Two decades of Indian research on protein and energy requirements of goats were reviewed. Protein requirements for minimum maintenance derived from endogenous urinary and metabolic fecal nitrogen excretion in nitrogen-free and low-nitrogen metabolism studies were 1.23 to 1.61 g digestible crude protein (kg body weight).75. Based on balance studies at maintenance, requirements were 3.13 to 3.83 g digestible crude protein/(kg body weight).75. The coefficient to predict utilizable protein from body weight for goats was .89. From digestibility trials, protein requirements for growth and maintenance were 4.52 g and 5.55 g digestible crude protein/(kg body weight).75, respectively, for pregnancy and maintenance. Protein requirements for lactation were 4.95 digestible crude protein/(kg body weight).75 and for 1 kg 4% fat-corrected mild 46.56 g digestible crude protein. Energy requirements for maintenance were 125 to 163 kcal digestible energy/(kg body weight).75; for growth and maintenance 232.83 kcal; for pregnancy and maintenance 211.79 kcal; for pregnancy and maintenance 211.79 kcal; for lactation 198 kcal; and for 1 kg 4% fat-corrected milk 1520 kcal.
