The most satisfactory method for the organic farmer to reduce the risk of infection to lambs from internal parasites is to practise clean grazing, which reduces parasitic infection and increases lamb growth rate (Fig. 3.5). The most effective method of clean grazing is, as we have seen, to use a three year rotational system with sheep, followed by cattle, and then arable. This presupposes land that can be ploughed. On permanent pasture farms with no arable, beef and sheep should be alternated. To make this effective, it helps if there are as many beef livestock units as sheep. If the farm contains only sheep, then it is advisable to alternate on an annual basis between ewes with twins and ewes with singles. If the flock normally produces mostly... 

Personal interviews of horse owners and veterinarians and clinical research has revealed that many horses exhibit many of the symptoms of E+ toxicosis while consuming only small quantities in hay, small patches of E+ fescue hay in paddocks, or even by grazing a small quantity of E+ fescue under paddock fences (Cross et al., 1999). Therefore, pastures must be completely rid of E+ fescue to prevent toxicosis in horses. Personal experience and interviews with livestock owners throughout the United States attest to the extreme difficulty of ridding pastures of E+ fescue. Experience has shown that unless pastures are completely... 

According to the Food and Agriculture Organization of the United Nations (FAO) report entitled Livestock s Long Shadow [11], livestock production is achieved at a substantial environmental cost. On a worldwide basis, it contributes 18 % of global greenhouse gas (GHG) emissions. GHG emissions from animal production include CH4 directly emitted from domestic animals or livestock manures, and N2O emitted from land applied manures and grazed lands [12].
