What does ADG stand for in livestock terminology?

• A. Weight gained per day
• B. Average daily gain
• C. Milk production rate
• D. Daily feed intake

Answer: (B)

ADG stands for Average Daily Gain. It’s a key measure of how quickly an animal grows over a defined period, calculated by taking the total weight gained and dividing by the number of days in that period. This gives the typical amount of weight the animal puts on each day, usually expressed in pounds or kilograms per day. It focuses on growth performance rather than how much the animal eats or how much milk it produces. Daily feed intake measures consumption, not growth, and milk production rate is about lactation. So while “weight gained per day” conveys the idea of daily growth, ADG is the standard term used to summarize growth pace over time.
