Digestibility of standing herbage
The digestibility iri vitro of the clipped standing herbage samples
is shown in tables 67-117.
Digestibility of samples from 1978 which was not presented in the
progress report for 1978, is presented in this report in tables 118-121.

Chemical composition of the pastures
The results of protein, ash and mineral analyses are presented in
tables 61-114. These figures indicate the quality of the pasture available
for grazing but not necessarily of that which is eaten. The results show
similar trends as in previous years:
1) Fertilization results in a considerable increase in protein and
mineral content of pasture.
2) There is a noticeable decrease in protein and mineral content
during the grazing season.
3) There does not appear to be any difference in chemical composition
according to pressure of grazing.
4) Ash content is very variable indicating various levels of soil and
forces contamination in the samples.
Detailed statistical analysis of the results of all 5 years of the
experiment will be published separately.
