The technique of feeding vegetables to rabbits
The water content of vegetables is about 85%, its crude fiber content is low, the palatability is good, and rabbits are gluttonous. When the young rabbits were fed with vegetable leaves at the age of 90 days, diarrhea occurred in only a few days. If the rabbit has diarrhea after eating vegetables, stop feeding vegetables, feed more hay and dried leaves, and add 2% charcoal powder or 2% medicinal charcoal to the mixture or mixture for treatment. The nitrate content of vegetables increased due to heavy application of nitrogen fertilizer and herbicides in the planted soil or when they became red due to insect pests, drought and lack of sunshine.

Snake bite antidote of the immune system
New research suggests that immune cells called mast cells help protect mice from some poisonous snake bites and bee stings. Although the role of mast cells in helping to produce symptoms of anaphylactic shock, asthma and allergies is most clear, scientists also recognize that these cells play other auxiliary roles in the immune system in dealing with infection. The venom of many insects and reptiles contains chemicals that activate mast cells, so researchers generally believe that the role of mast cells worsen snake bites or insect stings
