How to put an end to antibiotics residues in fresh milk?

According to information feedback, the testing of fresh milk is very strict a few days ago, and antibiotic drug residues are often detected in fresh milk, resulting in a large number of fresh milk being returned and poured out, so how to overcome this imagination in actual production? How to reduce the economic loss of dairy farmers? Please give me some advice!-- this is indeed a headache, and all the dairy farmers I know are very conscious of it. As long as cows injected with antibiotics are milked separately and are not sold-what is the main reason why antibiotics are often detected in milk? Don't use ambiguous feed, just don't use drugs in your own breeding process! -- the incidence of cow mastitis is very high, how to prevent it? How to reduce drug use? Passing by, learning-- the incidence of mastitis in dairy cows is very high. How to prevent it? as long as cows are treated with antibiotics, they must be milked separately and fed to the calves. -- key prevention and control efforts, 60 grams of calcium glucosamine 80 grams added to the prevention and treatment effect is good-- cattle injected with antibiotics, 48 hours after stopping the drug sampling, with E50 monitoring. Cattle injected with antibiotics were sampled 48 hours after withdrawal and monitored with E50. We have a similar problem. Antibiotics were detected in W2k (a9r "a! ^% G! d) milk station.

There are no antibiotics in the material.; b $w5i9G" y% | & Y "j! r # ^ + B mastitis, nipple bath, medication and other factors have been ruled out. I don't know why? I asked the teachers.
