How to Increase Milk Production in Dairy Goats

By Dr Duncan Houston

Improving goat milk production starts with healthy does that can eat enough, maintain condition and move comfortably through a consistent milking routine. Feed matters, but so do udder health, water, housing, parasites and the way kids are managed.

A falling milk yield can reflect a normal change in lactation. It can also be the first sign of a feeding problem, mastitis or another illness.

The aim is more high-quality, saleable milk from healthy goats, with a worthwhile return after production costs.

Quick Answer

Increase milk production in dairy goats by matching nutrition to lactation stage, providing reliable water, protecting udder health and maintaining a consistent milking routine. Use forage testing, individual milk records and body condition assessments to identify what is limiting production. Investigate sudden drops in yield promptly, especially when a doe stops eating, becomes unwell or develops abnormal milk. Measure milk quality, kid growth and costs alongside litres produced.

Decide what better production means for your dairy

Start with the product you intend to supply.

A dairy selling drinking milk may prioritise volume and consistent supply. A cheese producer also needs to consider fat, protein and processing performance. Neither benefits from extra milk that must be discarded.

Useful goals include:

• More saleable milk across the whole lactation.

• Appropriate fat and protein production.

• Fewer mastitis cases and less discarded milk.

• Healthy kids and replacement animals.

• Better maintenance of doe condition.

• Lower production costs per unit of saleable milk.

Confirm the buyer’s requirements for composition, bacterial counts, somatic cell counts, residues and delivery.

The doe producing the most litres today is not automatically the most profitable doe over her lifetime.

Understand the normal lactation curve

Milk production usually rises after kidding, reaches a peak during the following weeks and then gradually declines. Peak production commonly occurs around four to eight weeks after kidding, although the timing varies.

Lactation persistency describes how well a doe maintains production after that peak.

Compare animals at similar stages. A first-lactation doe, a mature high-producing doe and a goat approaching the end of lactation should not be expected to produce the same amount.

A gradual late-lactation decline can be normal. An abrupt fall, particularly with appetite loss or udder changes, needs investigation.

Choose breeding animals using records

Select for the system you can support, including climate, forage availability, housing and market requirements.

Assess:

• Recorded milk production across complete lactations.

• Fat and protein results.

• Udder attachment, teat placement and milking suitability.

• Udder health and treatment history.

• Fertility, kidding performance and longevity.

• Feet, temperament and ability to maintain condition.

Breed influences milk volume and composition, but individual performance matters. Compare animals within the herd and use reliable breeding information where available.

When choosing a buck, examine the performance and health of his female relatives or daughters where records exist. A strong pedigree is more useful when supported by results relevant to your dairy.

Prepare does before kidding

The next lactation begins with management during pregnancy.

Review body condition before joining and throughout gestation. Where practical, use pregnancy scanning to identify does carrying multiples and plan their feeding accordingly.

Late pregnancy brings increasing nutritional demands while abdominal space for feed can become restricted. Both inadequate nutrition and excessive body condition can increase the risk of pregnancy toxaemia.

Maintain accessible feed, water and shelter. Avoid leaving late-pregnant does to compete with stronger animals or travel unnecessarily long distances.

A heavily pregnant doe that stops eating, separates from the group or becomes weak needs urgent veterinary assessment. Pregnancy toxaemia can progress to neurological signs and recumbency.

Feed for the doe’s actual production level

A lactating doe needs nutrients for maintenance, milk production and, depending on her stage, growth or pregnancy.

Balance the complete ration for energy, protein, effective fibre, minerals and vitamins. A goat-experienced nutritionist can use bodyweight, milk yield, milk composition and forage analysis to calculate requirements.

High-quality forage should provide the foundation. Test hay and assess pasture availability rather than assuming a full feeder or green paddock supplies adequate nutrition.

Compare feeds on a dry matter basis, which excludes their water content. This makes comparisons between fresh forage, hay and concentrates more meaningful.

Feed type	Useful role	What needs attention
Good-quality pasture and suitable browse	Provides forage and nutrients	Seasonal quality, accessible quantity and poisonous plants
Grass hay	Maintains forage intake when grazing is limited	Digestibility, maturity and wastage
Lucerne or other suitable legume forage	Contributes protein, energy and calcium	Balance within the complete ration
Formulated dairy goat concentrate	Supplies additional energy and nutrients	Feeding rate, meal size and suitability for lactating goats
Suitable fibre-rich by-products	Can complement other ingredients	Composition, storage and consistent supply
Targeted protein or mineral supplements	Correct an identified shortfall	Existing nutrients in forage, concentrates and water

Choose supplements to fill the gap left by the forage. A high protein percentage on a feed bag does not, by itself, prove that the complete diet is suitable.

Increase concentrates gradually

Sudden increases in grain can cause ruminal acidosis, reducing appetite and potentially causing severe illness.

Introduce or increase concentrates progressively, commonly over about two weeks, using a plan appropriate to the ration. Maintain effective fibre and avoid large, irregular meals.

Watch for reduced cud chewing, poor appetite, loose faeces and abdominal discomfort after a feed change. Stop further increases and contact the veterinarian if these develop.

Inspect feed left behind. Goats can sort ingredients, so the ration they consume may differ from the one formulated.

Check whether every doe can reach the feed

Watch the animals while they eat.

Dominant goats may take preferred ingredients or block younger, smaller or recently kidded does. If possible, group animals according to production stage, condition and feeding requirements.

Provide adequate feeding space and keep feed fresh and accessible. Record refusals and wastage.

If the herd average looks acceptable but several does are losing condition, individual access may be more important than adding feed for the whole group.

Protect body condition during early lactation

Milk production can rise faster than feed intake after kidding, causing does to draw on body reserves.

Some early-lactation condition loss may occur, but progressive or excessive loss needs attention. Handle goats when assessing condition, because their coat and body shape can hide changes.

Review thin animals individually. Insufficient intake, competition, parasites, teeth and disease can produce similar outward signs.

As production declines later in lactation, adjust feeding to rebuild appropriate reserves without allowing excessive fat gain. This is also an opportunity to prepare for the next pregnancy.

Make drinking water easy to access

Provide clean, palatable water continuously.

Check troughs and automatic drinkers daily for contamination, flow and accessibility. A functioning drinker may still refill too slowly when the whole group returns from milking.

Place water where lactating does can reach it without crowding or unnecessary walking. Requirements increase with milk production, dry-feed intake and hot weather.

When several goats suddenly produce less milk, check the water supply immediately. Review recent changes in water source or quality as well as whether water is physically available.

Use goat-appropriate minerals and supplements

Assess minerals as part of the whole ration. Include those already supplied in concentrates, forage, water and free-choice products.

Dairy goats need an appropriate balance of calcium, phosphorus, magnesium, salt and trace minerals. A sheep mineral programme may not meet a goat’s copper requirements, while excessive supplementation can still be harmful.

Avoid stacking mineral products or repeatedly giving boluses because milk production is disappointing. Investigate whether a deficiency actually exists.

If sheep share the property, prevent them from accessing goat supplements that are unsuitable for sheep.

For probiotics, yeast products and other additives, define the intended benefit before purchasing. Ask whether the evidence applies to lactating goats on a comparable diet and how the response will be measured.

Keep milking regular, calm and consistent

Many dairy goats are milked twice daily. Whatever system is used, maintain predictable intervals and a routine that staff can perform consistently.

Record missed milkings, changes in timing and whether kids had access to the udder. These affect how much milk is collected and can confuse comparisons.

A practical milking routine includes:

1. Check the doe’s demeanour and udder.

2. Examine foremilk from each half for visible abnormalities.

3. Prepare teats using an appropriate pre-milking hygiene procedure.

4. Dry teats with an individual clean towel before milking.

5. Milk gently using correctly functioning equipment.

6. Apply an appropriate post-milking teat disinfectant.

Follow product instructions for contact time and use. Keep abnormal milk out of the saleable supply.

Clean hands or gloves, dry teats and hygienic equipment help reduce contamination and the spread of infection.

Have the milking machine checked for goats

Vacuum, pulsation, liners, cluster fit and removal settings must suit the animals and equipment.

Incorrect settings or worn components can damage teats and contribute to udder health problems. Arrange routine servicing and investigate liner slips, teat swelling or uneven milking promptly.

Avoid leaving cups attached unnecessarily after milk flow has finished. Check whether one udder half finishes before the other.

When several animals develop teat-end damage or udder problems together, include the machine and milking routine in the investigation.

Interpret goat somatic cell counts properly

Somatic cell count, or SCC, measures cells in milk and helps assess udder health. It is not a bacterial count.

Goat SCC is influenced by infection, but also by factors such as lactation stage, number of previous kiddings and season. Do not apply a dairy cow threshold to goats without appropriate interpretation.

Use:

• Trends for each doe.

• Comparisons with goats at similar lactation stages.

• Findings from each udder half where indicated.

• Clinical examination and milk culture.

• Laboratory methods appropriate for goat milk.

A rising count deserves attention even when the milk looks normal. Equally, one elevated result does not establish the cause.

Research in dairy goats supports interpreting SCC alongside physiological factors and bacteriological testing. Processor acceptance limits and diagnostic thresholds serve different purposes.

Know what each milk-quality result tells you

Measurement	What it helps assess	What it cannot establish alone
Milk volume	Production and collection trends	Whether milk is safe or production is profitable
Fat and protein	Composition and potential product value	The complete cause of a nutritional problem
Somatic cell count	Udder inflammation and health trends	The organism involved or whether every rise represents infection
Bacterial count	Microbial quality of collected milk	Whether contamination originated in the udder, equipment or storage
Residue testing	Presence of the substances covered by the test	Whether every possible residue or contaminant is absent

Use the results together. For example, rising bacterial counts should prompt a review of udder health, cleaning and cooling rather than an automatic assumption that every goat has mastitis.

Look for mastitis before it becomes obvious

Clinical mastitis may cause clots, flakes, watery or bloody milk, udder swelling, pain and reduced production.

Subclinical mastitis can occur without obvious changes in the milk or doe. This makes individual records and testing valuable.

If mastitis is suspected, contact the veterinarian about examination and collecting a clean sample from each affected half. Sampling before antibiotics can improve the usefulness of culture, but must not delay urgent treatment of a sick doe.

Use a separate milking arrangement or milk affected animals last under the herd’s control plan. Keep their milk out of the saleable supply.

Protect milk after it leaves the udder

Good udder health can be undermined by dirty equipment or inadequate cooling.

Remove milk residues from equipment promptly and follow a validated cleaning and sanitising procedure. Inspect seals, liners and surfaces where deposits can accumulate.

Cool milk rapidly to the storage temperature required by the processor and food-safety programme. Check actual milk temperature and cooling performance rather than relying only on a refrigerator or tank setting.

Milk that looks and smells normal is not automatically safe to drink raw. Pasteurisation reduces pathogen risk; hygienic collection does not replace it.

Plan kid feeding alongside saleable milk

Milk collected in the bucket is not necessarily the doe’s total production.

In dam-reared or shared-milking systems, kids may consume substantial quantities. Record nursing access when comparing yields, and monitor kid weights so milk allocation supports growth.

Newborn kids need adequate colostrum promptly after birth. Protect this priority before allocating milk for sale.

For artificial rearing, use a suitable feeding programme, consistent mixing and thoroughly cleaned equipment. Confirm that every kid is drinking enough, especially small kids and multiples.

Where caprine arthritis encephalitis is a concern, follow a veterinary colostrum and milk-management programme. Infection can spread through infected colostrum and milk. Do not pool milk from unknown-status animals without considering that risk.

Provide dry housing and comfortable access

Give goats a clean, dry resting area and protection from rain, wind and excessive heat.

Ventilation should remove moisture and stale air without exposing young kids to cold draughts. Keep leaking drinkers and muddy high-traffic areas away from bedding.

Ensure all animals can access shelter. A building offers little protection if dominant goats prevent others from entering.

Review the route between housing, feed, water and the dairy. Steep slopes, slippery ramps and long walks become more difficult for heavily pregnant, lame or recovering does.

Provide secure fencing, comfortable footing and enough space for goats to move away from one another.

Reduce heat stress before milk production falls

Lactating goats are vulnerable to heat stress even when the breed is considered heat tolerant.

Provide shade for the whole group, reliable drinking water and adequate airflow. Avoid prolonged crowding in holding areas, and schedule handling for cooler periods where practical.

Watch for increased panting, reduced appetite and animals clustering around limited shade or water.

Open-mouth breathing, marked weakness or collapse requires immediate attention. Humidity and poor overnight cooling can increase risk even when the daytime temperature seems familiar.

Keep feet, parasites and chronic disease under review

Observe gait daily and arrange hoof trimming according to growth and condition. Persistent lameness needs examination rather than repeated trimming without a diagnosis.

Use a goat-specific parasite programme incorporating worm egg counts, clinical assessment, grazing management and checks of treatment effectiveness.

Drench options for goats producing milk for human consumption can be limited. Check the exact product, goat dose and milk withholding instructions with the veterinarian. Do not copy a sheep or cattle programme.

Investigate recurring weight loss, enlarged joints, hard udders, abscesses and repeated illness. Include incoming-animal testing and appropriate biosecurity in the herd plan.

Plan breeding and drying-off

Record mating dates, expected kidding dates and intended dry-off dates.

Review body condition, current production and udder health before drying a doe off. The programme should prepare her for the next kidding while managing the risk of udder infection.

Do not withhold drinking water to force milk production down.

Any dry-period medication should be selected by the veterinarian for that doe and production system. Keep treatment and withholding records linked to her identification.

What could explain a sudden drop in milk?

First decide whether the problem affects one doe, a group or the entire herd.

A whole-herd change makes shared factors such as water, feed, heat, milking equipment or routine particularly important. A single affected doe needs close attention to her udder, appetite, movement and general health.

Level of concern	What you notice	Possible explanations and action
Lower concern	Gradual decline late in lactation, with normal appetite and condition	Review the lactation curve and ration
Needs investigation	Persistent unexplained decline in an otherwise bright doe	Check nursing access, collection records, intake and udder health; arrange assessment
Urgent	Sudden fall with abnormal milk, painful udder, appetite loss or lameness	Contact the veterinarian the same day
Emergency	Collapse, inability to stand, severe bloat, breathing difficulty or neurological signs	Seek immediate veterinary help

Around kidding, metabolic disease and infection deserve particular attention. Do not assume a doe producing little milk simply needs more grain.

When is this an emergency?

Seek immediate veterinary help for:

• Collapse, severe weakness or inability to stand.

• Seizures, blindness or marked incoordination.

• Severe abdominal swelling or breathing difficulty.

• A rapidly worsening udder problem with a very unwell doe.

• Severe diarrhoea with dehydration.

• Heat distress with weakness or collapse.

A late-pregnant doe that stops eating also needs urgent assessment because pregnancy toxaemia can deteriorate quickly.

Keep the animal safe and comfortable while arranging care. Do not force oral drenches into a goat that cannot swallow normally.

Track production and profit together

Keep individual records where possible. Bulk-tank figures can hide a declining doe or changes in the number being milked.

Track daily yield, days since kidding, fat and protein results, SCC, mastitis, discarded milk, body condition, kid growth and treatment history.

Record all milk withholding periods and use appropriate residue checks under the dairy’s veterinary and food-safety programme before treated milk returns to the tank.

For a proposed feeding change, calculate:

Additional margin = additional milk income − additional feed, labour and other variable costs

Include wastage and discarded milk. This measures the change’s contribution, not the whole farm’s profit.

Set a review date. Extra feeding is worthwhile when it produces a useful response without compromising health or simply increasing costs.

A practical improvement plan

1. Set the target. Define saleable volume, composition, quality and cost goals.

2. Find the main losses. Review low yields, mastitis, discarded milk, kid losses and feed wastage.

3. Check the animals. Assess udders, condition, appetite and movement.

4. Audit feed and water. Test forage, weigh supplements and watch goats eating.

5. Review milking and cooling. Observe the complete routine and service equipment.

6. Make targeted changes. Prioritise the largest constraint with the vet and nutritionist.

7. Measure the response. Monitor wellbeing daily and review comparable production trends weekly.

Act on illness immediately rather than waiting for the next scheduled production review.

Common mistakes to avoid

• Increasing grain before investigating why yield has fallen.

• Feeding every doe the same ration regardless of production stage.

• Applying cow SCC thresholds directly to goats.

• Ignoring kids’ milk intake when comparing collected yield.

• Overlooking water flow, teat damage or poor cooling.

• Chasing more litres while does lose excessive condition or costs exceed returns.

What is the best feed for increasing goat milk production?

A balanced ration based on good-quality forage, with supplements matched to the doe’s requirements. There is no single ingredient that reliably corrects every cause of low production.

How much milk should a dairy goat produce each day?

It depends on breed, age, lactation stage, health, nutrition and nursing access. Use comparable herd records rather than treating one daily figure as a target for every doe.

Does milking more often increase production?

It can affect yield, but the response varies. Consider nutrition, udder health, labour and the value of additional milk before changing frequency. Correct problems in the existing routine first.

Does a high somatic cell count always mean mastitis?

No. Infection is important, but non-infectious factors also influence goat SCC. Interpret trends alongside lactation stage, clinical findings and appropriate milk testing.

Can milk production recover after mastitis?

Some does recover well, while others have lasting loss of production because of udder damage or persistent infection. Early assessment helps, but the outcome depends on the cause and severity.

Build production the herd can sustain

The best dairy improvements support milk yield, udder health, doe condition and kid survival together.

Start by finding what is limiting your goats. Consistent feeding, comfortable housing, reliable milking and early veterinary investigation provide the foundation for production that remains worthwhile across the whole lactation.
