Calculate total weight gain, average daily gain (ADG), feed-to-gain ratio, and feed cost for cattle, pigs, or other livestock.
Enter initial and final weights, days on feed, and total feed intake to get ADG, F:G ratio, and feed cost.
Total Gain (lb) = Final Weight − Initial Weight
ADG (lb/day) = Total Gain ÷ Days
Feed:Gain Ratio = Total Feed Intake ÷ Total Gain
Cattle from 500 to 800 lb in 120 days, eating 3,000 lb feed: Gain = 300 lb. ADG = 300÷120 = 2.5 lb/day. F:G = 3000÷300 = 10:1. Feed cost at $0.10/lb = $300.
1. Weigh animals at start and end. 2. Record days on feed. 3. Track total feed consumed. Calculate.
ADG and feed conversion are key profitability metrics in livestock production. Lower F:G ratios mean more efficient conversion of feed to saleable weight.
Not accounting for shrink (animals lose 2-5% weight in transit). Using inconsistent weighing times (full vs empty gut). Confusing F:G with G:F (inverse).
