If you are raising dairy cows or buffaloes for milk, one of the most important questions you will face every single day is: how much feed to give dairy cow per day ? Give too little and milk production drops. Give too much and you waste money. Get it right and your animals produce consistently, stay healthy, and keep your dairy business profitable.
The good news is that calculating how much feed to give a dairy cow per day is not complicated once you understand the basic rules. In this guide, we will break it down clearly and practically, using examples that apply directly to dairy farming conditions in Nepal and the Terai belt region.
Whether you are a new dairy farmer or have been farming for years, this guide will help you feed smarter, spend less, and get more milk from every animal in your herd.
Why Getting the Feed Quantity Right Matters So Much
Feeding dairy cows is not a guessing game. Underfeeding is one of the most common and costly mistakes dairy farmers make. Research from dairy nutrition studies shows that a dairy cow or buffalo that is underfed by even 1 kg of concentrate per day can lose 1 to 2 litres of daily milk production over time.
At a milk price of NPR 70 to 80 per litre in the Butwal and Rupandehi market, that is a loss of NPR 70 to 160 per day, per animal. Over a 300-day lactation cycle, that adds up to NPR 21,000 to 48,000 in lost income from just one cow.
On the other side, overfeeding causes obesity, reduces fertility, and wastes expensive feed. The goal is precision: feeding exactly what your animal needs to perform at its best.
The Two Types of Feed Every Dairy Cow Needs Daily
Before we get into quantities, it helps to understand that a dairy cow’s daily diet has two main parts:
1. Roughage (Bulk Feed)
Roughage includes green fodder, dry straw, silage, and hay. It fills the rumen, supports healthy digestion, and provides fibre. Roughage alone, however, cannot supply enough protein and energy for a high-producing animal. A dairy cow needs 15 to 25 kg of roughage per day depending on her size and production level.
2. Concentrate Feed (Compound Cattle Feed)
This is where products like Cosmos compound cattle feed come in. Concentrate feed is nutrient-dense and provides the protein, energy, calcium, phosphorus, vitamins, and trace minerals that roughage cannot supply in adequate amounts. The quantity of concentrate feed is what most farmers need to calculate carefully based on their animal’s milk output.
How Much Feed to Give Dairy Cow Per Day: The Simple Formula
The most widely used method for calculating concentrate feed for dairy cows is based on milk production. The standard formula used by dairy nutritionists is:
Feed 1 kg of concentrate for every 2 to 2.5 litres of milk produced per day, plus a maintenance allowance of 1 to 1.5 kg for body upkeep.
Practical Examples
- A dairy cow producing 5 litres per day needs: (5 divided by 2.5) + 1.5 = approximately 3.5 kg of concentrate feed per day
- A dairy cow producing 10 litres per day needs: (10 divided by 2.5) + 1.5 = approximately 5.5 kg of concentrate feed per day
- A buffalo producing 8 litres per day needs: (8 divided by 2) + 1.5 = approximately 5.5 kg of concentrate feed per day
Daily Feed Quantity Chart for Dairy Cows and Buffaloes
| Animal Type | Milk Yield (litres/day) | Concentrate Feed (kg/day) | Roughage (kg/day) |
| Dairy Cow | 5 | 2.0 to 2.5 | 15 to 20 |
| Dairy Cow | 10 | 4.0 to 4.5 | 18 to 22 |
| Dairy Cow | 15+ | 6.0 to 7.0 | 20 to 25 |
| Buffalo | 5 | 2.0 to 2.5 | 15 to 20 |
| Buffalo | 8 | 3.5 to 4.0 | 18 to 22 |
| Buffalo | 12+ | 5.0 to 6.0 | 20 to 25 |
Note: These are general guidelines. Actual quantities may vary based on breed, body weight, feed quality, and season. Always consult a livestock advisor for a personalised feeding plan.
Factors That Affect How Much Feed to Give Your Dairy Cow Per Day
The formula above is a starting point, but several factors can increase or decrease the amount of concentrate your cow needs:
Body Weight and Breed
A heavier animal has higher maintenance requirements. A Murrah buffalo weighing 500 kg will need more feed than a smaller crossbred cow weighing 350 kg, even if their milk production is similar. Local breeds in the Terai generally have lower maintenance requirements than high-yielding exotic crossbreeds.
Stage of Lactation
Animals in early lactation (first 100 days after calving) are at their peak production and need the most feed. Cows in late lactation or in a dry period need significantly less concentrate. Pregnant animals in the dry period still need a maintenance ration plus extra minerals for the developing calf.
Season and Heat Stress
During Nepal’s hot summer months, dairy animals eat less and drink more. Heat stress directly reduces both feed intake and milk output. During this period, split feed into 3 smaller meals throughout the day and ensure cool water is always available. Add mineral and vitamin supplements to compensate for reduced appetite during peak summer and winter months.
Roughage Quality
Good quality green fodder like maize silage or Napier grass provides more energy and protein than dry straw alone. If your roughage quality is poor, you will need to increase concentrate slightly to compensate for the nutritional shortfall.
How to Feed Dairy Cows Properly: Practical Tips
- Divide the daily concentrate ration into two or three meals rather than one large feeding. This improves digestion and reduces the risk of acidosis.
- Always feed roughage before concentrate to stimulate the rumen and prevent digestive upsets.
- Introduce new feed or a new brand of cattle feed gradually over 7 to 10 days to allow the rumen bacteria to adjust.
- Keep feed troughs clean. Leftover or stale feed can reduce appetite and introduce mould or bacteria.
- Never feed concentrate without roughage. Roughage is essential to maintain healthy rumen function.
- Make sure fresh, clean drinking water is always available. A cow producing 10 litres of milk per day drinks 50 to 80 litres of water daily.
Why Cosmos Compound Cattle Feed Makes Daily Feeding Easier
When you use a scientifically balanced compound cattle feed like Cosmos, you do not need to separately source and mix protein, mineral, vitamin, and energy supplements. Everything your dairy cow needs is already formulated in the right ratios in every kilogram of feed.
Cosmos cattle feed contains a balanced ratio of crude protein (minimum 16 to 18 percent for dairy animals), metabolisable energy, calcium, phosphorus, and essential trace minerals like zinc, copper, and selenium. Vitamins A, D, and E are included to support immunity, fertility, and overall body condition.
This means you can follow the simple formula above, use the feeding chart, and trust that every kilogram of Cosmos feed you give your cow is doing exactly what it should.
Frequently Asked Questions (FAQ)
Q1. How much feed to give dairy cow per day if she is not producing milk?
A dry cow (not producing milk) still needs a maintenance ration to keep her body in good condition and support the growing calf. Typically, 1 to 2 kg of concentrate feed per day along with adequate roughage is sufficient during the dry period. Increase the ration in the last 2 to 3 weeks before calving to prepare the cow for lactation.
Q2. What happens if I give too much concentrate feed to my dairy cow?
Overfeeding concentrate can cause rumen acidosis, which is a dangerous condition where the rumen becomes too acidic due to rapid fermentation of starch. Symptoms include loss of appetite, loose dung, and reduced milk production. Always stay within recommended quantities and split the ration into multiple meals.
Q3. Can I give the same amount of feed to my buffalo as my dairy cow?
Not exactly. Buffaloes generally have a higher body weight than most dairy cows, so their maintenance requirement is slightly higher. Use the same formula (1 kg of concentrate per 2 litres of milk) but adjust for body weight. A 500 kg buffalo needs about 0.5 kg extra for maintenance compared to a 400 kg cow.
Q4. How do I know if my cow is getting enough feed?
The best indicator is body condition scoring (BCS). A well-fed dairy cow should score between 3.0 and 3.5 on a scale of 1 to 5. If your cow is losing body condition while maintaining the same milk output, she is likely underfed. If she is gaining weight excessively, reduce the concentrate ration slightly.
Q5. Should I change the feed quantity in summer and winter?
Yes. During summer heat stress, split feed into 3 smaller meals and provide extra minerals. In winter, animals need slightly more energy to maintain body temperature. Always have fresh water available year-round and add vitamin and mineral supplements during extreme weather months.
Q6. Is compound cattle feed better than mixing my own feed at home?
Homemade feed mixes are difficult to balance accurately without laboratory testing. The protein, mineral, and vitamin ratios can vary significantly from batch to batch, making it hard to maintain consistent milk production. Compound cattle feed like Cosmos is manufactured under controlled conditions with precise formulations so your animals receive the same balanced nutrition with every feeding.
Conclusion: Feed Right, Milk More, Earn More
Knowing how much feed to give your dairy cow per day is one of the most practical and valuable skills you can develop as a dairy farmer. It directly impacts milk yield, animal health, and your bottom line.
Start with the formula: 1 kg of concentrate for every 2 to 2.5 litres of milk per day, plus your maintenance allowance. Use the feeding chart above as a reference. Choose a quality compound cattle feed like Cosmos that gives your animals the complete nutrition they need in every kilogram.
And remember: feed quantity is just one part of the picture. Clean water, good roughage, regular health checks, proper housing, and a consistent milking routine all work together to keep your dairy animals productive and profitable.
