Experiment on Control of Ketosis in Dairy Cows

Abstract

An experiment was carried out for 2 years to study the effects of synthesized adrenocortical hormone, calcium preparation, antibiotic, and sulfa drug upon the control of ketosis. A total of 539 dairy cows were treated with these agents for postpartum weakness, retained placenta, postpartum paralysis, puerperal fever, dystocia, and milk fever, which were accompanied by mastitis in some animals.
1. No ketosis occurred to 30 cows administered with 100mg of predonisolone
2. Ketosis was induced in 11 of 509 cows administered with 100mg of predonisolone and 250 ml of “newgrone” (25g of calcium borogluconate and 5 mg of pilocarpine hydrochloride per 100 ml). Almost all the 11 cows had shown high milk yields.
3. The frequency of occurrence of ketosis after the experimental treatment was about one-tenth of that before this treatment.
