The value of rumen inoculations and of diets containing sweetening agents for calves weaned on to dry food at three weeks of age

The successful outcome of early weaning and dry feeding of calves would appear to depend upon, among other things, the early establishment in the calf’s rumen of a microbial association similar to that in the adult ruminant. Inoculating the rumen of such calves with’ rumen contents from older animals might be a method of hastening this development. In an earlier experiment in this series (Preston, 1956), it was found that by substituting linseed cake meal in place of dried skimmed milk in the meal mixture caused a reduction in consumption of the mixture and adversely affected growth rate. This indicated that it might be beneficial to incorporate in the diet some form of sweetening agent.
