Prices for cows in Argentina's Cañuelas Market have surged by 35% in recent weeks, reaching 1,350 pesos per live kilo, due to a combination of factors including a cow shortage, tax changes, and increased demand from China. The rise in cow prices is benefiting breeders, enabling them to reinvest in new cows and raise prices for pregnant cows and heifers. The improved demand is also boosting the value of calves expected to be sold in future harvests. Additionally, the Argentine government has eliminated export duties on beef, further contributing to the price increase.
