Alan Bair, Assistant County Agricultural Agent Spring Fever We all look with great an ticipation for the coming of Spring. Sure, it means a lot of work, but there seems to be enough of that all year ’round! Traditionally spring has meant a big jump in milk production. The Spring flush was influenced by a number of things, one of the biggest reasons being that nature has a way of having most cows freshen at that time of year. Your good management, along with the influence of milk marketing, has pretty much eliminated the effects of spring freshening. The other spring picker-upper is good green pasture. Oh yes, we always looked forward to the extra milk that it would bring. Ever stop to think why we got the big boost from pasture? Obviously the cows were missing something in their winter-time stored feed that the pasture could provide. In other words, we held our cows back all winter while we complained about the small milk check. Let’s come out of hibernation and find out what the problem is. Back up a few months and critically look at what you were feeding. Remember your father or possibly grandfather talking about a winter-time “ailment” of cows called hollowhorn? More correctly it should have been called hollowbelly. Did you really feed your cows enough this winter’ I don’t mean enough to fill them up, but sufficient nutrients to enable them to produce at their potential. The first step to feeding enough nutrients is to know what you rare feeding Better take note of this now for next winter’s feeding Spring will not last forever Streptomycin Warning Dr. Sam Guss, Our Penn State Extension Veterinarian reminds us that the U. S Food and Drug Administration has established a zero tolerance for streptomycin and dihydrostreptomycin in animal tissues The use of this antibiotic both for intramammary dry treatment and intramuscularly for almost everything is a potential source of tissue residues Cull dairy cattle are being sampled at slaughter for tissue residues of these and other antibiotics. Cows which have been given dry treatments containing antibiotics should be withheld from slaughter for at least 30 days Cows given in tramuscular injections of penicillin and streptomycin should be withheld from slaughter at least 60 days. It is often customary to give larger than label doses of this com bination of antibiotics because they are relatively cheap and some dairymen and veterinarians behc\c larger doses are necessary Tissue residues remain for much longer periods following excessive doses, FDA has warned that unless the necessary precautions are taken to prevent tissue residues, there will be much stricter regulations regarding their availability and use. Milk Squirt The average U. S. dairy cow produces almost a ton of edible and highly digestible nutrients a year. A cow producing 16,000 pounds of milk in a 10-month period supplies an amount of protein equal to that in the edible parts of eight 1200-pound steers, or 28 200-pmmd hogs
