Lancaster Dairy Day I (Continued from Pag* AM) The rule of thumb advise given was that all new cattle brought onto the farm should be suspect of having contagious mastitis or whatever threatening disease until proven differently. As a suggested practice, isolate new purchases and milk them last (However, milking a cow last means that it has a greater chance of picking up an infection that already exists in the herd, so ideal ly, a separate milking unit could perhaps be used on only new cattle until a reasonable isolation period has passed and somatic cell count tests show no problem.) Prc- and post-dipping with the a proper solution teat dip is always recommended, and both speakers emphasized the importance of fol lowing this practice. Dry cow therapy, culling, clean ing machinery correctly, and maintaining a clean, dry environ ment for cattle will help prevent many incidence of mastitis. Culturing milk samples from high SCC cows will also help far mers because they can start fight ing any problems early and with out wasting time using useless treatments.

At the same time, the production of desirable components such as lactose, casein and calcium is depressed in cows with high soma tic cell counts. Further, the experts said that a high somatic cell count is usually caused by contagious mastitis, instead of environmentally caused infections. Sardillo also said that while the emphasis on preventative action plans for mastitis have focused on the environment, the pathogens, farmers have to consider that the cow is also a major influence in susceptibility to getting infections if a cow is stressed and that stress reduces the cow’s immunological response abilities, the mastitis is more likely to occur and become more devastating. Sardillo also explained that mastitis is more damaging to the long term profitability of the cow than merely having a milk reduc tion during one lactation.

She explained that as the while Mood cells attempt to pass from within the cow, past the milk producing cells, in order to attack the invading bacteria, that the milk-producing cells are frequent ly destroyed. This results in lost milk-producing cells and scar tissue development She also said that tests have shown that as many as 90 percent of heifers have shown infections of mastitis bacteria before thqjr first lactation. Sardillo talked about some work being done on using dry cow treat ment on first-calf heifers about 60 days before freshening. However, while two area veter inarians said they have clients who are using the practice, Sardillo and Hutchinson explained that the majority of mammary tissue deve lopment in a cow occurs during the first lactation. This is important because, while infusing with heifers with an anti biotic has been shown in some stu dies to reduce the amount of masti tis by half, there is still a question about how long antibiotic residues & Plasson® Broiler Drinker ♦Automatic Belt Tightener ♦Cast Solid Belt Pullers Full Compliment of Optional Accessories Hours!

According to Sardillo, the possi bility exists that fanners could end up with contaminated milk and that milk from heifers treated as such should be tested for residues before adding the milk to the bulk tank. Further, unless a fanner uses artificial insemination, and can be certain of freshening dates, the far mer may end up dumping quite a bit of milk if the heifer calves ear lier than expected. Hutchinson, Sardillo and the practicing veterinarians Brian Reed, with Hutchinson, Trayer and Reed; and Darcie Stolz, of Strasburg also said that the use of dry cow treatment on heifers should not be done without the per mission and guidance of an approved veterinarian, as the use of the antibiotic treatments is an “extra-label” use, and that it is illegal for lay people to use at their own disgression. Especially with heifers, the insertion of the applicator tip should be restricted, and the teat LIM ♦ • Dump Truck Loads • Spreaders Available Rohrer’s Quality Hi-Cal Damp Lime 88% CCE ENP67 55% 65% 98% NOW ONLY $ 5 50 Per Ton (Picked Up) gR) [ED ST Registered with PA Department of Agriculture BARTVILLE WELDING SHOP I't ’ \ ohK Kij (tin,i mi 1.1 I* \ i ■'( i ,J -i!

Dr. Stephen Spencer, a well known Penn State milking equip ment expert, also discussed vari ous aspects of equipment that can cause teat problems and how to deal with them. According to Spencer, a com mon occurance with teats is the formation of a ring-like callous on the teat end. Some people think, because of the appearance of the callous with a vacuum systems that the vacuum is actually pulling out some of the the inside of the teat end. This is not true. The callous is formed because of the closing down on the end by the liner. The key to preventing teat prob lems is to make sure equipment is clean and that vacuum settings, pipleline slope, pipe diameter, and liner type are all capatable. If the system was not designed correctly is will cause problems. For more information on masti tis and milking equipment, contact a local extension office.
