According to one chief economist culling more than 150,000 head of cattle will have a similar impact on the sector as a drought. I noticed whenever there was drought, performance of Agriculture related companies were below expectations. If culling is equal to drought, then there could be some impact on the sector in the short run. I take these things as short term events. Whenever there is good rain barring heavy rain during harvest season, Agriculture output will go up. During these types of situation, if panic set stock prices could go down. Those who miss promising stocks will begin to accumulate as long as they see great value and growth. Those who panicked when there was short term animal disease such as bird flu and mad cow missed some multibagger opportunities.
