NITROGEN BALANCE EXPERIMENTS

• A more accurate evaluation of protein may be obtained by using the results of nitrogen balance experiments.
• In such experiments the ‘N’ consumed in the food is measured as well as that voided in faeces, urine and any other ‘N’ containing products such as milk, wool or eggs. When the ‘N’ intake is equal to the out put the animal is in ‘N’ equilibrium.
• When the intake exceeded the out go, it is in positive value, when the out go exceed the intake the animal is in negative value.
