热带牧草的草酸含量众所周知，热带奶牛的平均产奶量远远低于温带奶牛。在印度，每头奶牛的平均年产量约为400磅（I），在波多黎各约为2000磅（2）。在美国，每头奶牛的平均年产量远远超过5000磅，部分平均值超过8000磅（3）。波多黎各机构。有关奶牛群改良的研究表明，在适当的管理下，波多黎各的奶牛群产量可以与美国的同类奶牛群产量相等（4）。这些机构对大幅提高波多黎各牛群牛奶产量的前景非常乐观。在适当的管理中涉及的许多复杂因素之一是护理-
Oxalate Content of Tropical Forage Grasses It is generally known that the average milk production of the dairy cow in the tropics is far below that of the dairy cow in the temperate zones. Average annual production per cow in India is about 400 pounds (I) and in Puerto Rico it is about 2000 pounds (2). In the United States, the average annual production per cow is well over 5000 pounds, with sectional averages of more than 8000 pounds (3).The various agencies of Puerto Rico. that are concerned with the improvement of dairy herds have shown that, under proper management, the production of dairy herds in Puerto Rico can equal that of similar herds in the United States (4). These agencies are very optimistic about the prospects for increasing greatly the milk production of herds in Puerto Rico. One of the many complex factors involved in proper management is the care-
