Corn Silage for Young Dairy Calves: Forbidden or Forgotten?

Abstract

Although corn silage is an acceptable forage source for dairy calves, its use in calf diets remains questionable, particularly regarding its digestibility in young animals. The objective of this review article was to elaborate on whether and how corn silage may be fed as a fiber and energy source to young dairy calves. Corn silage is considered as one of the most important forage and energy sources for dairy cattle. Corn silage comprises approximately 50% of total mixed ration (TMR) for dairy cows (as-fed basis). Corn silage is a palatable, digestible, and high-energy forage that can be incorporated into young calf diets, as well. Dry matter content, particle size, starch and energy level, and mycotoxin contamination are the important factors that must be taken into account when deciding to utilize corn silage in diets for young calves. As such, corn silage may be fed to young calves under controlled conditions, and seems to be a forgotten energy-fiber source for young dairy calves. However, proper feeding management care must be taken to avoid corn silage to become a forbidden choice due to its inappropriate use. Future quantitative and qualitative studies are required for optimal uses of corn silage in diets for young dairy calves.
