Beware of vitamin b deficiency in pigs in winter
Symptoms: vitamin B2 (riboflavin) deficiency, growth retardation, vomiting, skin rash, hair removal and so on. When vitamin B3 (pantothenic acid) is deficient, diseased pigs have poor appetite, poor growth, dysentery, cough, hair loss, movement disorders, especially the "goose step"-like movement posture. Vitamin PP (nicotinic acid) deficiency, diseased pig appetite, weight loss, severe dysentery, skin cracking, covered with black crusts, neurological disorders, anemia.
Prevention and treatment: in the preparation of pig diet, pay attention to the full supply of vitamin B-rich bran, silage, germination feed and so on. If corn is used as the main feed for a long time, which can cause vitamin PP (nicotinic acid) deficiency, corn should be reduced and bran, silage, germinated feed and tuber succulent feed should be increased.

Prevention and treatment of duck infectious serositis
[Preventive measures](1) Strengthen feeding management to avoid too high density and crowding of ducks; ducks should be all in and out, disinfect empty houses for 2~4 weeks; bedding should be kept as dry as possible. (2) The vaccine for immune prevention of this disease has been used to prevent this disease and the effect is good. Ducklings were immunized with formalin inactivated vaccine prepared from different serotypes of strains once at 2 and 3 weeks of age, respectively, and no disease occurred at 7 weeks of age. However, the vaccine should be used twice, so it is difficult to popularize in field. Escherichia coli and duck plague were also produced
