Chemical Feed Additive to Fight Marek’s Disease Reported Discovery of a chemical compound that shows promise as a feed additive to reduce mor tality and visceral lesions caused by Marek’s disease in chickens has been reported by scientists from Merck & Co., Inc. They said that the compound, called AUS, will have to undergo extensive field testing for further evaluation of its safety and ef ficacy before any marketing decisions can be made. Some field trials are already in progress. In artificial infections with several strains of the herpes-type MAKE US PROVE IT!

The action of AUS in these tests proved to be primarily prophylactic; it prevented the symptoms of Marek’s disease from developing in the chicken. Dr. T. Y. Shen, Director of Chemical Research- Inflammation and Viral Disease of the Merck Sharp & Dohme Research Laboratories, traced the long history of discovery and described testing results in a paper presented at the annual Purina Dairy Conditioner Special can prepare cows for good production at low cost Ph: 464-3431 West Willow “Fetter Power Pays” LD LEADERS IN N If you’re not among the many good local dairymen who have started mixing Purina Dairy Conditioner Special with your own grain to build a research proved dry cow ration, it can pay you to check into this low-cost way of feeding dry cows. Purina Dairy Conditioner is a 16 percent protein ration, fortified with extra Vita mins A and D plus phosphorus to help guard against milk fever. To help you save on dry cow feeding, Purina Research recommends varying feeding levels, depending on cow condi tion and the quality of your roughages. For example, if a cow is in good condi tion and your roughages are of excellent quality, you would feed less Purina dry cow ration than if the cow were in only fair condition and if the roughages were of only fair quality. •Reg.

C. on September 15. A major contributor to the commercial development of a Marek’s disease vaccine, Merck has been marketing its ‘Dep tavac-HVT’ vaccine under license from the U. S. Depart ment of Agriculture since March 1 this year. Concurrently, however, the company has maintained a research program started in 1965 to find a chemical means of controlling the poultry disease that causes losses estimated as high as $l5O million a year. In the course of this program, Merck scientists screened many known anti-virus and anti-tumor compounds and determined that none had protective action at non toxic levels. Other approaches turned out to be more productive. Tests with several hundred sulfanilamide derivatives showed that a number of them had some degree of activity against Marek’s disease, but that this activity was in no way associated with their Statement of Ownership, Management, Circulation Required by the Act of Congress of October 23, 1962 (Section 4369, Title 39, United States Code) Of the Lancaster Farming published weekly at Lititz, Penna for October 1, 1971.

The Occupational Safety and Health Act of 1970, went into effect July 1, 1971. Described as one of the most important pieces of legislation of its type ever passed, it provides that both employers and em ployees have separate but related responsibilities and rights with respect to achieving safe and healthful working conditions. Attention should be directed to Using Purina Check-R-Mix* formulas we can build you a low-cost dry cow ration, combining Purina Dairy Conditioner with your grain. Or, if you’re feeding low-protein roughages, it may pay you to feed Dairy Conditioner “straight” just as it comes from the bag. More and more successful area dairymen are proving that good dry cow feeding pays off in extra cow condition and extra milk production in the next lacta tion. For example, 100 to 200 pounds of additional body weight at freshening can pay off in 1,000 to 2,000 pounds of extra milk during the lactation.

It was from this phase of the program that AUS was developed. Merck indicated that field trials are being conducted chiefly under broiler growing conditions. Chicks will be put on feed con taining AUS from the outset and will remain on such feed throughout the growing period. Is Described a unique feature of the law requiring action by employers of all types, including farmers with hired help. This is a provision for recor dkeeping. It requires that em ployers maintain and make available to the U.S. Department of Labor accurate records of work-related deaths, injuries and illnesses, except those requiring only minor first aid treatment. Employers must also keep records of employe exposure to potentially toxic materials or harmful physical agents, and their employes must be notified of exposure to such toxic materials or harmful agents. This latter provision is especially applicable to farmers applying dangerous pesticides in cropping operations A booklet titled Record- Keeping Requirements Under the Williams-Steiger Occupational Safety Act of 1970 is available from regional offices of the U.S. Department of Labor.
