Basic Definitions and Terminologies
BalancedDiet→Onewhichprovidesdifferentkindsofnutrientsincertainquantities
andproportionsofalltherequirednutrients
Optimizing→ Make the best use of a resource (or) Most effective use of a resource
Animal Production → Meat, milk and eggs
Animal Productivity → Birth rate, mortality rate, off-take rate, etc.
