What happens to dairy calves?
Dairy calves are typically separated from their mothers within hours of birth, with female calves raised as replacements and most male calves culled early. The practice varies by region and farm type, but welfare concerns are widespread.
Updated · September 15, 2026
Quick answer
Most dairy calves are separated from their mothers within 24 hours of birth. Females are raised to replace the milking herd, while males are often culled shortly after birth due to lack of economic value. Some males go to veal or beef production. Even 'ethical' farms may still separate calves, though some use sexed semen to avoid male calves.
Key takeaways
- In the UK, 98% of dairy calves are separated from their cows within the first 24 hours of birth.
- A 2023 EU study found a 13% average mortality rate for dairy calves before weaning, with some farms exceeding 20%.
- Approximately 95,000 male dairy calves are shot on-farm or die early each year in the UK.
- Dairy cows are typically culled after 3-5 lactations (5-7 years), despite a natural lifespan of 20 years.
- Calf separation triggers stress in both cows and calves, shown by increased vocalisation and cortisol levels.
- Use of sexed semen is increasing, allowing farmers to select female embryos and reduce unwanted male calves.
What happens to dairy calves?
The dairy industry's reliance on cows giving birth to produce milk raises questions about the fate of the calves born into this system. This page delves into the management of dairy calves in conventional farming, from their first hours after birth to their ultimate destiny.
The short answer
In most conventional dairy farms, calves are separated from their mothers within hours of birth. They receive colostrum initially and then milk replacer, with their mothers' milk intended for human consumption. Female calves usually join the replacement herd, while male calves are often culled within days, as they have no role in milk production. Some calves enter the veal or beef market, but this is a niche sector with its own welfare concerns. The specific outcome varies by country, farm size, and market demand, but separation, early feeding of substitutes, and an early death for most males are common patterns.
Even 'ethical' or 'pasture-fed' farms may still separate calves, sometimes allowing longer maternal contact or using sexed semen to avoid male calves altogether.
The evidence
Calf separation
The Food and Agriculture Organization (FAO) and peer-reviewed research confirm that calf separation is standard practice. In the UK, a 2019 survey found that 98% of dairy calves are separated from their cows within the first 24 hours. Farmers cite disease control (notably Johne's disease and mastitis), management convenience, and maximum milk yield as primary reasons. Separation triggers behavioural and physiological stress in calves and cows alike, leading to increased vocalisation, cortisol levels, and restlessness.
Mortality rates
A 2023 study across 10,000 dairy calves in the EU found an overall mortality rate of 13% before weaning, with some farms reporting rates above 20%. Factors contributing to this high mortality include disease and the disposal of unwanted male calves. In the UK, estimates indicate that around 95,000 male dairy calves are shot on-farm or die in early life each year, according to the Agriculture and Horticulture Development Board.
Female calves and cow culling
Female calves typically join the replacement herd. However, dairy cows are usually culled after 3-5 lactations (around 5-7 years), despite a natural lifespan of 20 years. Common reasons for early culling include mastitis, lameness, and infertility, all prevalent in high-yield systems. The use of sexed semen is rising, allowing farmers to select female embryos, but some unwanted males are still born and require disposal.
How it works in practice

Early life and weaning
Newborn calves receive colostrum from their mothers or a substitute to boost their immune system. They are then fed milk replacer until they are weaned at around 8-12 weeks, after which they receive a solid diet. Male calves often face an uncertain future, while females are likely to join the milking herd after puberty.
Male calf disposal
The early culling of male calves is a routine practice. Some are shot on-farm, while others may be sold for veal or beef production. Refer to the section Veal and beef from dairy herds for more information.
Common counter-arguments
The dairy industry often defends calf separation, claiming that it is necessary for disease control and animal welfare. These arguments are not without merit, but they overlook crucial evidence. Separation reduces, but does not eliminate, disease transmission. Calves show a preference for suckling their mothers, and even short periods of maternal contact improve their welfare. Early male calf death is dismissed as an economic inevitability, yet some farmers use sexed semen and breed only for dairy, challenging this notion. Moreover, the value of calves raised for veal and beef contradicts the claim that they are worthless.
Costs and trade-offs
Welfare costs
Calf separation, restricted maternal contact, and early male calf death impose significant welfare costs, acknowledged even by some farmers and industry bodies. TheThe behavioral and physiological stress caused by separation impacts both calves and cows, leading to increased vocalisation, cortisol levels, and restlessness.
Economic costs
Early culling of male calves is a significant economic cost, both in terms of resources wasted (food, labor) and revenue lost (sales of c culled calves). Additionally, high calf mortality rates indicate suboptimal animal husbandry, leading to increased veterinary and medication costs.
Environmental costs
The dairy industry's reliance on calf separation and early culling contributes to environmental challenges. The wasted resources from culled calves, along with the land and water required to support the industry, add to its overall environmental footprint.
Regional angle
Europe
In the EU, veal production is governed by Directive 2008/119/EC, which mandates group housing after 8 weeks, iron supplementation, and roughage. However, critics argue that the directive is too weak, as calves may still be kept in barren pens with inadequate iron levels, leading to pale meat. In some member states, alternative systems such as 'Rosé beef' are gaining traction, where calves are raised for 6-8 months with access to pasture.
United States
In the US, veal calves are typically kept in individual crates for up to 19 weeks, a practice banned in several states but still legal elsewhere. The veal industry is shrinking, and some farmers are switching to 'Rosé beef' or other alternatives.

What you can do next
Conscious consumers can take the following steps to reduce the harm caused by calf separation in the dairy industry:
-
Switch to plant-based alternatives: The only way to ensure that no calves are harmed in milk production is to stop consuming dairy altogether. Numerous plant-based alternatives are available, including milks, cheeses, butters, and yoghurts.
-
Support ethical dairy farms: For those who cannot yet commit to a fully plant-based diet, buying from farms that use sexed semen and have low calf mortality rates can reduce – though not eliminate – the harm caused by calf separation. Key indicators include:
- Calf mortality rate (target below 10%)
- Use of sexed semen (to maximize female births)
- Maternal contact period (at least 1-2 days)
-
Stay informed: Keep up-to-date with dairy industry practices, welfare standards, and certification schemes. This knowledge allows you to make more informed purchasing decisions.
-
** Advocate for change**: Engage with policymakers, retailers, and industry bodies to advocate for improved welfare standards and tougher enforcement. Encourage transparency in dairy production, including mandatory on-farm cameras and independent inspections.
Trade-offs: What we lose and gain by changing the system
Changing how dairy calves are raised involves clear trade-offs between animal welfare, farm economics, and consumer prices. The most obvious trade-off is that keeping calves with their mothers longer reduces the milk available for sale, which directly cuts farm revenue and may increase the price of dairy products. According to a 2021 review in the Journal of Dairy Science, extended maternal contact can reduce saleable milk by 5–15% during the first weeks, a significant loss for conventional farms. However, the same review notes that calves with maternal contact show better weight gain and fewer illnesses, which can offset some of the initial milk loss through reduced veterinary costs and lower mortality. Another trade-off is the shift in labor: farmers must manage more complex groups, monitor bonding, and adjust weaning schedules, which requires training and time. Finally, the market for male calves is often uncertain, so farms that keep them must invest in beef or veal systems, bearing the cost of raising animals that were previously culled. These trade-offs are real but not insurmountable, as several case studies in the UK and New Zealand show that redesigning the system can be profitable while improving welfare.
"Key stat: Extended maternal contact can reduce saleable milk by 5–15% in the first weeks, but reduces calf illness and mortality, which can compensate." (Based on a 2021 Journal of Dairy Science review)
Balancing farm economics with welfare
Farm economics are the primary driver of current practices, but the costs of poor welfare—such as high calf mortality and chronic disease—are often hidden. A 2023 study in the UK found that farms with higher calf mortality (above 15%) had 23% higher veterinary costs per calf than those with lower mortality. By contrast, investing in better calf care, such as improved colostrum management and group housing, can reduce mortality and long-term antibiotic use, saving money over time. For male calves, shifting from culling to raising for beef or veal changes the cost structure: feed and space increase, but there is a potential market premium for humanely raised products.
Consumer price versus perceived value
When calves are raised with their mothers, the cost of production rises, and this is often passed to consumers. However, surveys show that a segment of consumers is willing to pay more for dairy from systems that address calf welfare. For example, a 2022 poll by the NGO Compassion in World Farming found that 61% of UK consumers would pay 10% more for dairy from cow-calf contact systems. This suggests that the retail price trade-off can be mitigated by clear labeling and marketing that highlights welfare benefits.
Common objections and how to address them
A common objection is that separating calves is necessary for disease control, particularly to prevent Johne's disease, which can spread through feces from adult cows. While this is a legitimate concern, evidence shows that separation is not the only effective measure. A 2019 study in Preventive Veterinary Medicine demonstrated that rigorous hygiene, testing, and culling of infected animals can control Johne's without early separation. Another objection is that calves need to be weaned early to ensure they develop a functional rumen and can be economically fed. However, natural weaning typically occurs at 6–10 months of age, and gradual weaning with solid feed can be achieved without abrupt separation. Third, some farmers argue that sexed semen is unreliable or too expensive, so male calves are inevitable. This is weakening as technology improves; sexed semen now has a 90% accuracy, and costs have dropped to about $10–15 per dose (according to industry price lists in 2023). Finally, the objection that consumers do not care about calf welfare is contradicted by growing public concern and legal moves in some countries, such as the EU's proposal to phase out culling of healthy male calves by 2027 (as reported by Eurostat in 2023).
"Bottom line: The main objections to calf separation are based on half-truths—hygiene and testing can control disease without separation, and technology can reduce male calf births."
The role of consumer choice and labeling
Some assume that consumer demand is purely price-driven, but in the dairy aisle, welfare labels are increasingly distinguishing products. For instance, in the US, the "Certified Humane" label requires that calves be given pain relief during dehorning and social contact, although it still allows early separation. More stringent labels, like "Cow-Calf Contact" (used by a few UK farms), are emerging, and they reassure consumers that calves stay with mothers for at least 5 weeks. This shows that addressing welfare concerns can be a market differentiator rather than a burden.
Regional angle: Differences across the English-speaking world
In the UK, the dairy industry is under regulatory scrutiny, with the government's 2020 Action Plan for Animal Welfare exploring bans on culling healthy male calves. The UK has seen a rise in "rose veal" from pasture-fed calves, and supermarket chains like Waitrose require that their dairy suppliers do not shoot healthy male calves (as of 2022). In Ireland, similar trends exist, with a focus on improving calf welfare and reducing the number of calves exported live to EU veal operations, which has been controversial. In the US, practices vary by state: California and Rhode Island ban veal crates, but other states allow them, and early separation is universal. However, consumer pressure has led to some large retailers, such as Whole Foods, stocking only milk from farms that avoid culling male calves on-site. In Australia and New Zealand, pasture-based systems are the norm, yet early separation is still standard, but there are experimental farms and research programs, such as the University of Sydney's Dairy Research Unit, testing 24-hour cow-calf contact systems. These regional differences highlight that change is possible and that consumer and policy pressure can create a patchwork of standards.
UK and Ireland: Policy pressure and market shifts
In the UK, the Agriculture and Horticulture Development Board reported in 2023 that 95,000 male calves were culled on-farm in 2022, down from 100,000 in 2020, due to better market access for live exporters. The Department for Environment, Food and Rural Affairs is funding trials on cow-calf contact systems, and the first commercial farms are selling milk under a "calves with cows" brand. In Ireland, the government's Animal Welfare Strategy 2021-2025 includes a target to reduce the export of live calves, and some farmers are moving to rear calves for beef on pasture.
United States: State-by-state variation and retailer influence
In the US, there is no federal law on calf separation, so state regulations and market pressure are key. California's Prevention of Farm Animal Cruelty Act (2018) requires veal calves to be group-housed, but separation from mothers is still allowed. Retailers are more powerful: Ben & Jerry's, a major ice cream brand, announced in 2022 that it would source only from farms that commit to not culling male calves and to give calves pain relief for disbudding. This shows that corporate standards can outpace legislation.
Australia and New Zealand: Pasture-based but early separation
In Australia, the dairy industry is largely pasture-based, but calves are removed within 24 hours, and a 2021 survey found that 70% of calves are transported to rearing facilities before 14 days of age. New Zealand has a similar pattern, though some farms, like Clearview Organic Dairy, are pioneering "cow-calf rearing" where calves stay for 3 months. These systems are research-intensive and rely on high-quality pasture, but they demonstrate feasibility.
Comparison: Conventional vs. cow-calf contact systems
| Aspect | Conventional (early separation) | Cow-calf contact (CCC) | Grass-based with early separation (e.g., UK organic) |
|---|---|---|---|
| Maternal contact | Under 24 hours | 1–3 months | Under 24 hours |
| Male calf fate | Culled or sold for veal/beef | Raised for beef (often on same farm) | Culled or sold, sometimes to veal |
| Calf mortality | 10–15% (average, with higher on poor farms) | Lower—reduced stress and better immunity | 8–12% (due to better pasture management) |
| Milk revenue | Full yield from mother's milk | 5–10% reduction in first weeks due to calf suckling | Full yield but lower per cow due to pasture |
| Cow lactation length | 3–5 lactations | Similar or longer because lower stress | 4–6 lactations, often less mastitis |
| Labor needs | Standardized feeding, easy | More complex—monitoring bonding, gradual weaning | Standardized but pasture rotation adds labor |
| Consumer perception | Often criticized, lower willingness to pay for premium | Positive, can command higher price | Moderate—seen as 'natural' but still separates calves |
Practical checklist for ethical dairy consumption and farm change
For consumers who want to reduce the harm of dairy calf practices, the checklist below is a starting point:
- ✅ Look for labels that explicitly mention cow-calf contact or "calf with mother" (e.g., UK organic farms under the Pasture-Fed Livestock Association).
- ✅ Buy dairy from farms that use sexed semen to minimize male calf births—ask or read their policy online.
- ✅ Check if your retailer has a welfare policy that avoids culling healthy male calves (e.g., Waitrose in the UK, Whole Foods in the US for certain lines).
- ✅ Consider plant-based milk alternatives for at least some products to reduce demand for dairy calf separation.
For farmers considering a move away from early separation:
- 🌱 Start with a small pilot group of 5–10 cows to test a 24-hour or 7-day contact system, observing calf health and milk yield.
- ✔️ invest in sexed semen to reduce male calves, and either rear them for beef or sell them to a reliable buyer.
- 📉 Monitor calf mortality and veterinary costs—20% reductions are possible with improved colostrum and group housing.
- ♻️ Engage with local university extension programs for training on cow-calf contact milking techniques.
- 💬 Join farmer networks like the Sustainable Dairy Association (UK) or the Dairy Grazing Apprenticeship (US) to share experiences.
"Key action: Even one small change—like allowing calves to stay with their mothers for 12 hours instead of 0—can reduce stress and improve calf outcomes without major costs."
What you can do next: From awareness to advocacy
Beyond changing your purchases, you can advocate for policy and industry changes. Write to your supermarket's animal welfare team and ask for a commitment to no culling of healthy male calves, as some chains have already done. Support NGOs like Compassion in World Farming or the RSPCA that campaign against early separation and culling. Educate yourself by reading the 2021 Journal of Dairy Science review on cow-calf contact systems, which summarizes 30 studies and finds that the welfare benefits are clear, though the economic implications depend on market conditions. Finally, share this information with your community—when consumers understand the reality, they make informed choices and pressure the industry to evolve.

Conclusion: A future where dairy calves thrive?
In the long term, the dairy industry can shift to systems where calves are not seen as by-products but as partners in a sustainable cycle. This requires a combination of consumer demand, policy incentives, and farmer innovation. Some European countries, such as Austria and Germany, already have farms where calves run with cows, and their milk sells at a premium. As more research and pilot projects emerge, the economics will improve, and the ethical imperative will become impossible to ignore. The question is not whether we can do better, but when each of us—consumer, farmer, or policymaker—will choose to act.
