肉牛顾名思义以产肉为主的牛，这种牛与传统的农业社会用于耕地的牛不同，耕地的牛主要用于农业生产，不以为人们提供“肉”为最终目的，而肉牛的最终目的就是为人提供优质的牛肉，所以它具有躯体丰满，产肉性能好，肉质口感好等特点。

从需求端来看，猪肉是我国第一大肉类生产品类，占比维持在60%以上。根据国家统计局数据，2016-2018年，猪肉产量维持在5400万吨左右，占全国肉类总产量的比重为60%以上，2019年，受非洲猪瘟疫情影响，全国猪肉产量4255万吨，同比下滑21.26% ，创近17年来最低水平，占全国肉类总产量的比重下降至55.63%。

我们认为，当下优质养殖股的核心矛盾在于成长性而非周期下行风险。在非瘟常态化背景下，猪价高位宽幅震荡或是常态，而由于行业壁垒提高，优质企业超额回报或将提升，此阶段调整正为优质养殖股配置机会。首推牧原股份；重点推荐温氏股份，傲农生物；建议关注正邦科技，新希望，唐人神，金新农。
