Pork production is very scientific and the people who run it work very hard. Pork production begins with the insemination of the sow. Most common today is artificial insemination. The use of a boar in direct contact with the sows will initiate an “immobilization response” so that it can be bred. Because boars can be dangerous to use or expensive to house/feed, a product called Boar Mate can be used. This product contains boar pheromones and when sprayed in front of a sows nose, the combination of the spray and back pressure can bring her into a standing response. Cost and nutrition is the key to successfully feeding pigs. Feeding too many amino acids will cause some to flow over into the feces and urine. This is not a good thing for the environment. The large amounts of manure produced each day by pigs create a gas hazard. Without oxygen, some of the bacteria in the feces produce hydrogen sulphide (H2S). Odor can be controlled (although virtually impossible to eliminate) by the addition of certain enzymes or certain types of rocks to it to “eat away” the odor. People have a history of complaints on pesticides and their effect on human health. The use of pesticides is controlled and regulated by the Pest Management Regulatory Agency. Before a pesticide can be registered for use it must be tested for its effects and long-term effects on the environment, people, etc.
