Everthing about the cattle ranching plans sounded promising.However,the promise did not last long. It turned out that the grass-fed cattle from South America processed meats such as hot dog and cold cuts.
The grass-fed cattle did not bring high prices.
Even though demand for beef in the US and other nations was high,consumers in these nations were not willing to accept grass-fed beef,staying instead with beef fed on corn and grain.
一切关于牧牛业的计划听起来都是有前途的，然而，好景却没有持续很长时间，原来（那些）来自南美洲食草牛（被）加工成的肉类如热狗和冷盘。
食草牛并没有提高（牛肉的）价格，尽管牛肉的需求在美国和其他一些国家很高。这些国家的消费者并不乐意接受食草牛肉，反而愿意接受喂食玉米和谷物的牛（这句翻译的肯定有问题）谢谢回复
