The global milk production continues to grow and is now approximately 982 million tonnes. Worldwide, milk is among the most produced and valuable agricultural commodities. Asia has emerged as the highest contributor to the global milk production, and currently India is the largest milk producer in the world. The average per capita milk consumption is approximately 322 grams per day globally in 2023. Cow milk represents 81% of global milk production, followed by milk from buffaloes (15%), goats (2%), sheep (1%), and camels (0.4%). Other minor dairy species like yak, horse, donkey, reindeer, llama, and alpaca contribute less than 1% of global milk production, mostly in diverse climatic zones. The per-animal productivity varies by species and region. More than 150 million farmers raise dairy animals, and the dairy sector supports almost one billion people in their livelihoods. However, only 3% of the dairy farms have more than 10 cows. The average dairy herd size is approximately 2.4 cows per farm. Milk is mainly consumed domestically; only around 9% of total milk production is traded globally. Milk and dairy products (butter, cheese, skim milk powder, and whole milk powder) contribute approximately 14% to global agricultural trade. The major opportunities in the dairy sector are in the continuous production and demand of milk and dairy products, constant innovation, and adoption of modern technologies, despite the region-specific constraints broadly due to climate change, environmental regulations, feed and labor shortages, price volatility, disease outbreaks, antimicrobial resistance, infrastructure gaps, etc. A holistic region-specific, climate-smart practice and regulation, supportive labor and trade policies, and stronger disease forecast and control with judicial antimicrobial use can make the milk production sustainable.
