The analysis of cation‐anion difference of six important forage
The high performance and fitness of dairy cow relies on high quality forage.The difference between cation and anion in forage means cation‐anion difference(CAD), which has close relationship with some disease occurs in late perinatal period such as milk fever.The amount of sodium and potassium minus that of chloride and sulfur will be CAD.To prevent milk fever, using anion salt which contain chloride or sulfur in early perinatal period is feasible( Tucker et al.,1991).But the platability of anion salt is bad, and the price of anion salt is high.Forage usually have higher CAD than anion salt, but forage is more cheap, so feed forage with low CAD to dairy cow in early perinatal period will be benefit to prevent milk fever.
