 Tobacco Stems the Year Round 



Next to dogs, stomach worms are the most dangerous enemy 

 of sheep and lambs. They do not always seriously affect older 

 sheep, but hundreds of lambs suffer and die from this pest. 



How Lambs Become Infested 



The worms live in the fourth stomach. Mature sheep can 

 look healthy, yet carry over winter enough worms to kill all the 

 lambs the following summer. The eggs are scattered with the 

 droppings on pastures where they hatch and the young lambs 

 gather them up with the grass. 



There is no danger in cold weather. As soon as the weather is 

 warm the eggs hatch and if the lambs are kept on the infested 

 fields, trouble and loss is sure to follow. 



Symptoms of Stomach Worms 



Lambs get droopy and dull sometimes refuse to eat and lose 

 flesh rapidly. Often there is swelling under the jaws. The bowels 

 are loose and offensive and the skin gets chalky white instead 

 of pink as it should be on a healthy sheep. Death often results 

 unless effective and early treatment is given.
