Description
In an effort to find selection criteria for intake and digestibility, based on correlations with the same characters measured on animals, we have compared 4 to 6 grasses of similar heading dates for intake, palatability, digestibility by sheep, intake by goats and many laboratory tests. 1979 results were published for Lexington Congress. Results of 1980 and 1981 springs bear them out in several points :
- palatability was a very precise and stable test
- palatability, digestibility and goat intake were stable and correlated with each other
- soluble phenols were able to predict palatability and part of digestibility
-sheep intake was not reliable : it was very unstable, difficult to predict by laboratory tests, its correlations with othercharacters were very variable: good in 1981, bad in 1979, negative in 1980. More information is needed to understand its variations. The experiment has been enlarged to include milk production, 2nd spring grass growth and since 1983 dairy cows.
