Fat content: the average fat content in a cow is 3. 4, the average fat content in a goat is 3. 5% iii. Biological value: net protein utilization, egg protein: 94% available, milk protein: 85% available, corn protein: 60% available, navy beans: 38% available, animal proteins. Highly available protein can be absorbed i. e corn protein deficit in lysine and tryptophan: poultry and eggs. Various poultry species produce a second high quality food for human consumption eggs.
