Effect of Para-Amino Salicylic Acid on Growth of Male Holstein Calves^{1, 2,}

Department of Dairy Science, The Pennsylvania State University, University Park

ABSTRACT

It has been suggested that para-amino salicylic acid (PASA) would stimulate the growth of calves when included in the diet (2). A feeding trial has been conducted to test further this possibility.

Twelve male Holstein calves were divided into two groups at random. All calves had received colostrum for at least one day before being placed on trial. They were fed limited amounts of whole milk until ten days of age, along with milk replacement which was started at six days of age and continued through 42 days of age. Each calf received a total of 60 lb. of milk and 39.4 lb. of dry milk replacement. Calf starter was fed ad libitum until a maximum of 4 lb. was being consumed by each calf Group I. The differences in favor of Group II were statistically significant at the 1% level of probability for body weight and at the 5% level for height at withers and chest circumference.
