Effects of Dietary Levels of Energy and Protein at the Finishing Stage. 1.Performance and Pelt Production of Rex Rabbits

ABSTRACT Unlike meat-type rabbits 'Flemish Giant, New Zealand White or Californian] winch are slaughtered at 10 - 12 weeks old, Rex rabbit, a fine fur-producing rabbit, arc harvested at 6 - 8 monthold, The nutrient requirement at the 'finisher stage and for fur production purpose may be di...
