Description
In a rotational grazing experiment with dairy cows on monocullures of a diploid and 2 tetraploid cultivars of perennial ryegrass (Lolium perenne L.), at a high herbage allowance the average daily production of fat and protein together was significantly higher on the tetraploids. This was associated with a difference in herbage intake of on average 0.6 kg/cow/day of organic matter and a higher concentration of volatile fatty acids and a lower pH in the rumen.
