Daily milk collection in Sinaloa's Mazatlán dairy basin has fallen from a historical average of 100,000 litres to 85,000–90,000 litres, according to the local cattle association. Farmers have sold over 200 dairy cattle to neighbouring states in the past month as drought, weak subsidies and low farm-gate prices made herds unaffordable to maintain.
Lower regional milk output reduces local dairy supply and shifts demand toward feed inputs, while farms cutting herds add pressure on feed-grain and protein purchases. The effect on prices is local, with limited direct impact on national or world feed markets.
