ABSTRACT

Influence of season and physiological states of animals were determined on plasma urea nitrogen profile of crossbred dairy cattle (HF × Sahiwal) at 1700m altitude from mean sea level in Central Himalayas. Non-pregnant heifers (NPH) showed the highest PUN during both summer and winter seasons, whereas high yield early lactating cows (HYELC) and pregnant heifers (PH) the lowest PUN during summer and winter season respectively. Significant seasonal variations (P
