"Environmental protection pig" is very popular

Introduction: Pig's harm to the environment is mainly through the excretion of phosphorus in the feces to play a role Scientists at gulfer University in Ontario, Canada, recently announced that they have developed a "green pig" with 20 to 50 percent less phosphorus in feces than ordinary pigs using genetic engineering technology The new breed was developed by introducing some genes from mice and certain bacteria into the DNA of Yorkshire pigs This is the first valuable attempt by scientists to improve the environment by breeding genetically engineered animals, which is welcomed by environmental protection departments and pig farmers Annia rush, a female scientist in Poland, recently invented a new method of feeding pigs with lignite as feed additive, which not only makes the pigs fed less sick, grow faster and have good meat quality, but also reduces the environmental pollution caused by pig farms and coal mines Through more than seven years of observation and research, rush found that, perhaps due to genetic factors, pigs especially like to eat 50% humidity brown coal Coal can provide a lot of magnesium and iron for pigs, and organic acids in coal can absorb toxins in pig digestive system "It's black and hard, it's easy to dry, and it's not harmful to the environment," lash said According to this, rush, together with the scientists of the local petroleum and Coal Research Institute, has created a revolutionary "piggy coal ball" theory According to this theory, the manure of pigs fed on coal can be used as a cheap and effective fuel.
