| 1. | In both hand-fed and grazing animals changes in diet should be carefully noted .
必须详细记录人工饲养和放牧牲畜两者的食物变化。 |
| 2. | This article reviews the methods used to measure methane emissions from grazing animals
就有关放牧家畜甲烷气体的测定方法研究作了综述。 |
| 3. | Not too long ago and about 100 years ago before the advent of the lawn mower , lawns were kept short by grazing animals
100年前人类还没有割草机时，草坪通过食草动物保持短矮。 |
| 4. | Yet there are uses for marginal land . most often it is used as grassland . grasses provide excellent feed for grazing animals like cattle , sheep and goats
然而，边角土地也是有用的。通常用作牧场草地。牧草是食草鞋动物优质的食物，如牛，山羊和棉羊。 |
| 5. | Forage crops like clover and alfalfa could be planted . these members of the legume family provide high protein food for grazing animals . they also improve the quality of the soil
可以种稹草料作物，如三叶草和紫花苜蓿。这此豆属作物可以给食草动物提供高蛋白的食物。它们还可以改善土地的质量。 |
| 6. | Other contributors include methane released from landfills and agriculture ( especially from the digestive systems of grazing animals ) , nitrous oxide from fertilizers , gases used for refrigeration and industrial processes , and the loss of forests that would otherwise store co2
其它气体包括垃圾和农业（食草动物的消化系统）排放的甲烷、肥料中的氮氧化物、用于致冷和工业加工的气体，以及能够储藏二氧化碳的森林面积的减少。 |
| 7. | Other contributors include methane released from landfills and agriculture ( especially from the digestive systems of grazing animals ) , nitrous oxide from fertilizers , gases used for refrigeration and industrial processes , and the loss of forests that would otherwise store co2
其它气体包括从垃圾填埋和农业而产生的甲烷（食草动物消化系统） ，从肥料中产生的氧化亚氮，用于冷藏的气体和工业排出的气体，以及那些能贮存二氧化碳消失的森林。 |
| 8. | Other contributors include methane released from landfills and agriculture ( especially from the digestive systems of grazing animals ) , nitrous oxide from fertilizers , gases used for refrigeration and industrial processes , and the loss of forests that would otherwise store co2
其他的因素有在农业和废渣填满中产生的甲烷（尤其是来自食草动物消化系统的产物） ，农药、制冷、工业流程产生的二氧化氮，而原本能吸收二氧化碳的森林却正日渐消失。 |
