Adding coal to feed to produce high quality pork in Poland (6.30)

OA show ('918 '); Polish scientists invented the method of feeding pigs with coal in feed, and produced high-quality pork After seven years of research, rather, a Polish scientist, and her colleagues found that when lignite was added to pig feed, pigs not only grew faster, but also improved their meat quality "The pigs we feed with lignite are fatter, livelier and healthier than those fed with standard chemical additives," Ms Lasser said The nose of pigs is very sensitive They like the smell of coal very much " She said that after research, coal can provide pigs with a large amount of magnesium and iron The two substances can increase the hemoglobin of pigs by about 6%, which can effectively reduce anemia In addition, organic acids in coal can absorb toxins in the digestive system of pigs, increase the number of bacteria in the intestines and stomach, and reduce the possibility of diarrhea and other diseases in pigs The ancestors of domestic pigs are wild boars Wild boars often eat tree roots and soil with long tusks They grow very healthy Although they are surrounded in pigsty, they still keep the old habits and like to eat coal in the soil, which can make pigs increase appetite and speed up weight growth Compared with traditional feed chemicals, coal is cheap, and does not need veterinary management, which reduces the cost If further experiments prove that feed coal can be applied in a wider range, the invention can be widely used in the pig industry in the next few years in YCM
