EFFECTS OF ADDITION OF FIBER TO SIMPLIFIED AND TO COMPLEX STARTERS FED TO YOUNG DAIRY CALVES

Effects of adding fiber (10% cottonseed hulls) to simplified and to complex calf starters, fed as the only dry feed to four groups of eight calves each, were investigated. The simplified calf starter consisted of ground corn grain, soybean meal, and supplements of vitamins, minerals, and an antibiotic. The complex starter contained soybean meal, linseed meal, wheat bran, cracked corn, corn meal, crimped oats, alfalfa meal, cane molasses, dried whey, animal fat, and supplements of vitamins, minerals, and an antibiotic. Additions of fiber to the simplified and the complex starters resulted in increased feed consumption and weight gains. Estimated net energy requirements per unit of gain were similar. Weight gains and energy requirements per kilogram of gain were similar for calves fed either complex or simplified starters. General appearance and incidences of diarrhea were not affected by the dietary differences. Results of this research suggest that when a starter is used as a complete feed for young calves, too low a fiber level reduces weight gains. © 1969, American Dairy Science Association.
