EFFECT OF WATER RESTRICTION

• Moderate water restriction decreases  
  • feed intake                                                    
  • productivity
  • urine and faecal water excretion
•  Severe water restriction leads to 
  • rapid weight loss, increase in blood concentration
  • increased renal excretion of sodium, potassium and nitrogen                                                        
  • Increased pulse rate and rectal temperature especially at hot temprature because animal has no longer enough water to evaporate
  • Nausea, difficulty in muscular movements and death
