Dairy goat production continues to be a socially, economically and culturally important part of the livestock industry in North, Central and South America and the Caribbean islands. Goat milk, cheese and other dairy products offer consumers food products with nutritional, health and environmental benefits. In North America, Mexico produces the greatest volume of goat milk, but most is for family or local consumption that is typical of a mixed farming system adopted by subsistence farmers in dry areas. The United States is not yet a large global goat milk producer, but the sector has expanded rapidly, with dairy goat numbers doubling between 1997 and 2012. The number of dairy goats has also increased dramatically in Canada. Commercial farms are increasingly important, driven by rising demand for good quality and locally sourced goat cheese. In South America, Brazil has the most developed dairy goat industry that includes government assistance to small-scale producers and low-income households. As of 2017, FAO identified Haiti, Peru, Jamaica, and Bolivia as having important goat milk production in the Western Hemisphere. For subsistence goat producers in the Americas on marginal land without prior history of chemical usage, organic dairy goat production can be a viable alternative for income generation, with sufficient transportation, sanitation and marketing initiatives. Production efficiency, greenhouse gas emission, waste disposal, and animal welfare are important challenges for dairy goat producers in the Americas.
奶山羊养殖在北美洲、中美洲、南美洲以及加勒比群岛的畜牧业中,仍然是具有重要社会、经济和文化意义的一部分。山羊奶、奶酪及其他乳制品为消费者提供了具有营养、健康和环境效益的食品。在北美洲,墨西哥的山羊奶产量最高,但大部分用于家庭消费或当地消费,这是干旱地区自给农民采用的混合养殖系统的典型特征。美国尚未成为全球大型山羊奶生产国,但该行业发展迅速,奶山羊数量在1997年至2012年间翻了一番。加拿大的奶山羊数量也大幅增加。由于对优质和本地采购山羊奶酪的需求不断上升,商业化农场变得越来越重要。在南美洲,巴西拥有最发达的奶山羊产业,其中包括政府对小规模生产者和低收入家庭的援助。截至2017年,粮农组织认定海地、秘鲁、牙买加和玻利维亚在西半球拥有重要的山羊奶生产。对于美洲边缘土地上没有化学品使用历史的自给型奶山羊生产者来说,在有足够运输、卫生和营销举措的情况下,有机奶山羊生产可以成为一种可行的创收选择。生产效率、温室气体排放、废物处理和动物福利是美洲奶山羊生产者面临的重要挑战。
