In the Philippines,the wet season is a critical period for grazing animals.It is the time when livestock grazing in pastures experience problems of poor nutrition and gastrointestinal worms.Often,fields used as grazing land during the off season are planted in crops during the rainy season.Ruminants such as goats,cattle and buffaloes must then search for other areas where they can feed.Rainy days also bring worm problems,because the warm.moist enviroment encourages the worm eggs to hatch into infective larvae.These larvae move onto the moist leaves of grasses and shrubs,which the rumminants feed on.If animals are allowed to feed,whether loose or tetered,just after rain or early in the morning when grasses are still moist with dew,they may eat leaves covered in infective larvae.These larvae then mature into full grown worms in the stomach of the animals,The worms decrease the production of meat and milk,and reduce the ability of the animals to resist infections.To alleviate these problems,farmers generally avoid grazing their animals on rainy days,or in the early hours of the morning when the sun has not yet dried the dew.Some raisers may confine their animals in pens during the whole rainy season.Others may give their animals a drench with a chemical dewormer,adopt a rotational pattern of grazing,or feed their animals leaves of trees and shrubs which are known to have antihelminthic properties.
