Optimise your feed management with our free Animal Feed Calculator , designed to show you exactly how much feed your livestock need to reach their target weight using current UK market data.
Why Use Our Feed Calculator?
How It Works Input Animal Details:
Animal Type: Choose whether your animal is a cow or sheep.Starting Weight: Enter the current weight of your animal.Target Weight: Enter the desired weight you expect your animal to reach.Timeframe: Specify the number of months over which the animal is expected to gain weight.
Instant Calculation:
Weight Gain Needed: The difference between your target and starting weights.Feed Requirement: Based on standard feed conversion ratios (for example, approximately 6.5 kg of feed per kg of weight gain for cows and 5.5 kg for sheep).Estimated Feed Cost: Using the current average feed price (e.g. £0.28 per kg).
Personalise Your Results:
Benefits:
Accurate Feed Estimates: Know exactly how much feed is required to reach your target weight.Cost Efficiency: Plan and manage your farm’s feed budget with reliable cost estimates.Simplified Planning: Organise feeding schedules and purchasing decisions well ahead of time.Free Herdwatch Account: Enjoy comprehensive farm management features, including livestock tracking, financial management, and compliance tools.
