Newborn rabbits were a peak of death seven or eight days ago. The beneficial bacteria in the intestines only grew from scratch and in small quantities. If the environment is not clean or the cage is dirty, the mother rabbit develops mastitis or subclinical mastitis, or Due to contamination of pathogenic bacteria such as staphylococcus on the nipples of female rabbits on the bottom of the cage, the rabbits eat pathogens after eating milk. Since the beneficial bacteria in the intestinal tract cannot inhibit the proliferation of these pathogens, the pathogens increase rapidly in the intestine of the young rabbits. , causing diarrhea in pups. The pups pulled yellow loose stools and their urine was yellow. The puppies' hips, the inner sides of the two hind legs, and the rear abdomen were yellowed by feces and urine. They called the pups yellow urine disease. Prevention of the disease should do the following things: (1) Female rabbits are injected with antibiotics on the day of birth to prevent mastitis or subclinical mastitis; rabbithouses and rabbit cages are cleaned. (2) On the third day after childbirth, the rabbits were given drop-wise berberine hydrochloride injections, 3-4 drops of each, once daily for 3 days. (3) The pups started at the age of 11 days and were given a drip-feeding solution of probiotics, 1 ml each, once a day for 3 days, and the intestinal probiotics rapidly increased.
