Group 2; supplemented with ß-carotene (1 gr/day/each cow). Blood was sampled weekly from the animals during the experimental period of 5 weeks. ß-carotene and vitamin A levels in the blood samples were assayed by using HPLC. In group 2, plasma vitamin A and ß-carotene levels were increased statistically significant (P < 0.0,1, P As a conclusion, it will be useful to supplement ß-carotene in dairy cows when the plasma ß-carotene and vitamin A are low. |
