Abstract
The experiment was carried out on 60 bulls: 30 Black-and-White Polish Holstein-Friesian (PHF) and 30 hybrids with Limousine (PHFxLM). The effect of reducing the energy value of a diet to 80% maintenance requirement during the final 60 days on vitamin B12 level was investigated. The modified diet had no significant effect on cobalamine content in PHFxLM blood plasma. The level of B12 in PHF blood decreased significantly after a week of changing the diet but no significant effect at the end of the experiment occurred.
