Abstract

Twenty-fourWhite Fulani, Friesian and German Brown male and female calves aged between one and eighty-four days were used in these studies. Each of the calves was assigned to one of the following treatment:

  • Milk are given twice daily in addition to concentrate and grass,
  • Milk given twice daily in addition to concentrate
  • Milk are given once daily in addition to concentrate and grass,
  • Milk given once daily in addition to concentrate.

Digestibility studies were carried out on all the calves at the 4th, 8th, and 12th week of age and crude protein utilization was determined.

The results indicated that there were significant differences (P/0.01) in the crude protein digestibility between the treatments, and between the breeds. Both faecal- N and urinary nitrogen increased significantly (P/0.01) with age in all the treatments and breeds. The digestible crude protein (DCP) values of 0.81 to 0.92 and 33.8 to 45.3g/Wkg. 734.day were obtained for maintenance and maintenance plus growth from regression equations respectively for all the breeds.
