Cabbage, lettuce and other vegetables have less dry matter and less carbohydrate content. Feeding rabbits one or more vegetables for a long period of time can cause lack of certain nutrients and affect the growth and development of young rabbits.
The moisture content of vegetables is about 85%, its crude fiber content is low, palatability is good, and rabbits are greedy. Feeding young rabbits within 90 days of age with vegetable leaves will cause diarrhea in only a few days. If the rabbit suffers from diarrhea after eating vegetables, it should stop feeding vegetables, add hay, dry leaves, and add 2% charcoal powder or 2% medical carbon to the mixture or mix.
When vegetables are fertile due to planting, if they are re-applied with nitrogenous fertilizers, herbicides or insect pests, drought, and when the sunshine is insufficient, the nitrate content will increase. Rabbits greedy eat vegetables leaves and ingest more nitrate, stimulate the gastric mucosa, can cause gastroenteritis. After vegetables encounter pests, trampling, frost, stacking and transportation, especially in hot and humid weather, it is easy to make the nitrate contained therein become more toxic nitrite.
Fresh vegetables contain nitrite at 0.1 mg per kilogram. Naturally placed on the fourth day, it is 2.4 milligrams per kilogram; when rotting occurs, the content is as high as 340 to 384 milligrams per kilogram. As long as rabbits eat 100 grams of such vegetables can cause poisoning, and even death. When the amount of vegetables leaves and radish sprouts is large, such as adding chlortetracycline (0.1 g/ton), it can inhibit the growth and reproduction of reducing bacteria and prevent nitrite poisoning.
Mustard, rape, radish and other cruciferous vegetables contain mustard meal. It is a glycoside, under the action of mustard enzyme, it can produce thiocyanate, isothiocyanate, oxazolidinone, nitrile and other toxins, can inhibit the absorption of iodine in the thyroid gland, causing goitre; Nitrile also damages rabbit liver and kidneys. Therefore, cruciferous vegetables should be fed as little as possible or siled and fed (silage can be detoxified).
Feeding rabbits with vegetables attacked by aphids or cabbage caterpillars can cause conjunctivitis, stomatitis, gastroenteritis, rhinitis, vaginitis, abdominal pain, and diarrhea in rabbits. When feeding rabbits properly with vegetables, feed with low moisture content (such as bran, etc.) and feed with high crude fiber content (such as dried leaves, etc.) should be fed. The rabbits should be fresh vegetables without dew. Rotten vegetables can never be used to feed rabbits.
Human adenovirus has 51 serotypes, 6 subgroups A-F, and the genome is a linear double-stranded DNA molecule. Groups B, C, and E are associated with respiratory infections; groups A and F are associated with gastrointestinal infections, groups D and E are associated with eye infection; and groups D and E are associated with kidney and urinary tract infections. Adenovirus is acid-resistant, so it can continue to remain active through the gastrointestinal tract.
