After a cage has been built up in a reservoir, each year in the winter and spring seasons, it can be found that there are a small number of squid squid covered with bumps and arches. In severe cases, the spine bends and becomes soft, and a considerable part of the squid grows slowly. , often bleeding, and not easy to heal, infecting watery mildew, gills, enteritis and other diseases and death, resulting in low survival rate. According to the above symptoms, the author's initial diagnosis of salmon vitamin C deficiency was due to insufficient vitamin C content in herring feed.
First, the treatment immediately to the pharmacy to buy vitamin C pills, per kilogram of carp daily with 300 mg of vitamin C powder feed mixed feed, 15 days after the above symptoms significantly reduced, taking 25-30 days after the examination, no illness, but there are Sequelae caused by vitamin C deficiency.
Second, the causes and countermeasures Salmon vitamin C deficiency is caused by insufficient content of vitamin C in feed. Feeding too little green fodder in winter, plus feed processing, heat treatment will destroy vitamin C during the extrusion process (feeds are extruded at 80 °C -120 °C state, vitamin C is generally lost 40 - 60%, sometimes up to 80%, plus vitamin C in the storage will be oxidized, sun exposure will also cause vitamin C degradation, thus increasing the amount of vitamin C loss.
Therefore, when feeding pellet feed, you should mix appropriate amounts of vitamin C in the feed, and feed as much green feed as ryegrass as much as possible so that the carp can take the required vitamin C from the green feed, so as to achieve the purpose of preventing disease.
