Abstract: 
One of the native cattle in Khuzestan province of Iran is Najdi breed that is characterized by a hump in the withers area. As there is no information available about blood electrolytes of this breed in Khuzestan province, this study was carried out to determine the blood electrolytes of Najdi cattle in hot and cold seasons with respect to age and sex. Therefore, blood electrolytes of 180 Najdi cattle in different age and sex groups were determind by conventional laboratory methods. Serum calcium and phosphorous in female animals were affected by season, so that serum calcium and phosphorous levels were higher significantly in summer and winter, respectively (P<0.05). Serum phosphorous concentrations of adult female animals were significantly lower than immature animals, but calcium was not affected by age, and also sex. They had no effects on serum calcium and phosphorous. The serum concentration of sodium was higher in summer only in immature animals. In summer, adult female animals had lower concentrations of sodium in comparison with immatures but, sodium was not affected by sex. The serum potassium levels of females, with more than 6 months of age, in summer were higher than winter season, but potassium was not affected by age and sex. The serum chloride concentrations of animals, with more than 6 months of age, in winter were higher than summer. Female animals with more than 6 months of age had higher concentrations of chloride. Female calves had higher serum chloride levels than males (P<0.05).
