Dairy farmers with fifty or more cows whose calvings are spread out over the year may benefit from feeding fermented colostrum. Although this feed has not been tremendously popular in recent years, its low cost may make it more popular in the future. When properly diluted, fermented colostrum is an excellent feed, resulting in weight gains equal to those of calves fed whole milk or milk replacers. Containers of fermenting colostrum should not be exposed to direct sunlight. Plastic twenty-gallon garbage cans make ideal colostrum containers.
Bigger ones are too heavy to handle when full.
A disposable plastic bag lining the container makes cleanup easier and eliminates the need to scrub the container. The container should be filled with colostrum and set to one side until fermented. A tight lid should be fitted on the container to keep out flies, rats, and cats. Colostrum does not need to be stirred every day, but it should be stirred thoroughly before it is used as feed so that the fat, curds, and whey are adequately mixed. Fermented colostrum should not be stored longer than fourteen to thirty days.
