In all biological liquid sum of positive charge is equal to sum of negative charge

Electrolites in ration give that charges to the body Effective on electrical balance, acid-base balance and performance of animal

Balance of acid-base;

anion and cation balance in ruminants Electrolite balance in poultry

= difference between total anions and cations in rations/diets

Unit= miliequaval

Absorbtion and metabolism complicate the definition of real amount and properties of balance It is important to use electrolyte balance to correct any mineral deficiencies or toxicity in the construction of the ration

Exp: NaCl

Acid base balance is important for all life

Anion cation balance important in dairies for performance

In dry period the ration must be anionic for prevention of milk fewer

In poultry,

High temerature/ heat stress-increase the CO2 retention with respiration-change the electrolite balance- effected the;

• Egg Shell quality

• Health

• metabolism

In poultry,

To prevent from these negative effects, Should arrange the balance

Especially should supply the NaHCO3 instead of NaCl

The calculation formula:

Na + K – Cl

(Na + K) – (Cl + S) = miliequaval (mEq) or miliosmol (mOsm)

Additives are: ammonium sulphate, ammonium clorite, calcium sulphate, calcium clorite, magnesium sulphate and magnesium clorit
