Dairy & Livestock Calculators
Manage animal nutrition, milk pricing and seasonal fodder preservation for your herd.
Milk Fat & SNF Rate Calculator
Calculate the exact milk price per litre and your total earnings from FAT% and the lactometer reading (CLR), using the two-axis formula dairy cooperatives use.
Cattle Feed & Dry Matter Calculator
Work out daily dry matter need and balance green fodder, dry straw and concentrate feed from body weight and milk yield.
Silage Pit Capacity Calculator
Calculate bunker or trench silo volume, the tonnes of green fodder it holds and how many days it will feed your herd.
Cow Weight Calculator
Estimate cow, heifer, bull or buffalo weight from heart girth and body length using the proven tape measurement method.
Ghee Calculator
Calculate how much ghee your cow or buffalo milk will yield, or how many litres of milk are required for 1 kg of pure ghee.
Dairy Shed Size Calculator
Calculate covered roofed area, open paddock yard, manger length and water trough size for your cattle herd using BIS loose-housing standards.
Feed Cost Calculator
Calculate daily, monthly and yearly feed costs per animal and for your entire herd, with realistic prices for green fodder, dry straw, concentrate and mineral mixture.
Dairy Farm Income Calculator
Calculate monthly milk income, feed costs, overheads, net monthly profit and cost of milk production per litre for a 5, 10 or 50 cow dairy farm.
Silage Calculator
Calculate total silage required for your herd, bunker or trench pit volume and length, and days of supply with storage losses.
Milk Fat & SNF Rate Calculator
Calculate the exact milk price per litre and your total earnings from FAT% and the lactometer reading (CLR), using the two-axis formula dairy cooperatives use.
Milk, feed and fodder – the numbers that decide dairy profit
In a dairy, feed is usually the biggest cost and milk quality decides the price you are paid. A small change in fat or SNF, or a few kilograms of wasted feed a day, adds up to thousands of rupees over a lactation.

These tools use standard rules of thumb used by dairy cooperatives and animal husbandry departments. For a ration for high-yielding animals, ask your veterinary officer or the nutrition advisor of your milk union.
Frequently asked questions
What is SNF in milk?
SNF means solids-not-fat: protein, lactose and minerals. Most cooperatives pay on both fat and SNF, so both affect your price per litre.
How much dry matter does a cow eat?
Roughly 2.5–3.5% of its body weight per day, depending on milk yield. A 400 kg cow giving 10 litres typically eats about 12 kg of dry matter.
