U—Lancaster Farming, Saturday. December 12,1970 Highlights of Local 'Back to School' Milk Production Course About 30 Eastern Lancaster County dairy tamers have been “back to school” studying ways of improving the quality and production of the milk their herds produce Members of the Gaiden Spot Young Farmer Chapter have just completed a five week course on “Quality Milk Produc tion ” The course consisted of five meetings including. How Milk is Made, Sanitation of Dairy Equipment, Managed Milking and Bain Management, Herd Health, and Testing Milk for Quality The mam concern of the afrmer is to inciease production without saciifiemg quality of the product To do this the dairy faimei is finding it neces sary to pay closei attention to detail in all aspects of his milk ing routine, accoiding to Don ald M Robinson, adult farmer instructor in the Eastern Lan caster County School District Robinson coordinated the in struction, speakers, films and field trips for the five-part course Milking Equipment Much concern was raised over the merit of various types of milking machines and systems and techniques of milking The importance of correct vacuum levels, the stability of the vacuum at the teat end, the vacuum loss due to careless handling, the time icquired to properly prepare a cow and milk her, the anatomy of the udder and how it functions, and the selection of proper sanitiz ing agents were all stressed The array of dairy equipment testing instruments available to the farmer through the dairy equipment dealer was pointed out.

' Advances in the control of Mastitis were presented and discussed with emphasis -oa teat dipping and dry cow treatment as the most promising methods of control. Guest speaker Dr. Walter Trumbauer, Ephrata Veterinari an, pointed out that experiment al work on commercial herds using chlorine or iodine based teat dips after each milking, in combination with bacteria cul tures of cows being turned diy, followed with appropriate treat ment, has reduced incidences of Mastitis 80 to 90 per cent. Dairymen trying teat dipping were warned not to give up af ter a few weeks if they don’t see results. The farmer must stick with it for at least six months before results will be really evident. The group toured the new dairy barn of Andrew Stoltzfus of Elverson RD2. He was the outstanding Young Farmer' of Pennsylvania in 1969.
