2026年,由于玉米价格下跌,饲料成本降低,牛肉价格上涨,牛牛销售收入增加,因此爱荷华奶农正在打折,或在2026年赚取微薄利润。 Iowa dairy farmers are breaking even or making small profits in 2026, driven by lower corn prices reducing feed costs and rising beef prices boosting income from calf sales. 随着牛数量不断下降,牛肉需求不断增长,奶牛正在用像安格斯这样的牛群交叉饲养雄性幼崽,生产每只价值超过1 000美元的杂交手。 With declining cattle numbers increasing beef demand, dairies are crossbreeding male calves with beef bulls like Angus, producing crossbred steers worth over $1,000 each. 这一战略在牛奶收入中加上每100公斤2.50美元至3.50美元。 This strategy adds $2.50 to $3.50 per hundredweight to milk revenue. 农民现在养活大多数女性取代母牛,为男性使用牛牛,从强大的牛肉市场获取最大利润,同时管理剩余公牛幼崽。 Farmers now breed most females for replacement heifers and use beef bulls for males, maximizing profits from the strong beef market while managing surplus bull calves.
