AB  - With the development of modern sheep production, in order 
  to effectively improve the production efficiency of sheep, according to the 
  local natural resources and environment to implement the intensive breeding 
  of meat sheep has become the development direction of China’s 
  sheep industry. Feed is the basis of the aquaculture industry, accounting for 
  >70% of the cost of sheep production, at the same time, it related to the 
  growth and development, production and reproductive performance of sheep, nutrition 
  and feed problem is an important factor has long been plagued in development 
  of the sheep. In this study, all the male lambs were developed normally and 
  healthy for 3 months (Dorper Sheep x Small Tail Han Sheep F1) with an average 
  body weight of 16.2±2.1 kg, they were randomly divided into three treatment 
  groups (<I>ad libitum</I> feeding, 65% restricted feeding , 35% restricted feeding) 
  all experimental sheep were fed with TMR and free access to water, single caged 
  in metabolic cages, mainly use the digestion and metabolism trial and slaughter 
  method to infer the protein requirement of 20-35 kg sheep lambs (Dorper Sheep 
  x Small Tail Han Sheep F1). Through the digestion and metabolism trial and slaughter 
  method to speculate the prediction equations of nutritional requirements about 
  Dry Matter Intake (DMI) and Crude Protein Intake (CPI) for stall-feeding fattening 
  of 20-35 kg sheep lambs. Total body N content and retention were determined. 
  Growth pattern of the wool has a high influence on protein requirements of lambs. 
  Dorper Sheep x Small Tail Han Sheep F1 growing lambs used in the study showed 
  protein requirements for growth lower than those reported by the most nutritional 
  systems.
