Description
In 1970, the use of injected vitamins had been suggested as a means of increasing the rate of gain of steer calves, and improving the calving performance of beef cows in western North Dakota. Two trials were conducted using injected vitamins; one on steer calves and the second upon the usage of injected vitamins on cows. Injecting vitamins A, D and E on either a 28 day or a 56 day interval did not improve the rate of gain of either calves or yearlings that were being fed a high roughage ration. With the rations fed, there was no significant difference in the weight change of the cows, the number of calves lost, the birth weight of weaning weights of the calves between cows receiving the vitamin A injection and those not injected.
