On the unfertilized land the carcass weight of the calves in Sölvaholt
was poor. A great variation was between replicates. On the fertilized
land the carcass weight was also poor, but both on the fertilized and
unfertilized paddocks there was a considerable difference due to grazing
pressures. Other data concerning the experiment at Sölvaholt will not be
discussed here but referred to tables 55-58.

Livestock health
As in previous years the health of the sheep in Alftaver was good.
Two ewes were found on their back of which one died. In addition
one ewe was found dead at the beginning of the experiment. Three lambs
got sick during the experiment and one died, and in addition one was found
dead of unknown causes. Relatively few lambs got diarrhea.
In the experiment at Auókuluheiöi the health of the livestock was
similar as in previous years. However, several ewes got raastitis. Several
lambs got diarrhea.
The health of the sheep at Eyvindardalur was good.
At Hestur the health of the sheep was good. Fewer lambs got diarrhea
than in previous years.
The health of the horses (ponies) in the experiment in Kalfholt was
very good. Two ewes were found dead on their back, but otherwise the
health of the ewes was good. Several lambs got diarrhea and three died
during the experiraent.
As previously mentioned there was very little vegetation growth in the
pastures in Kelduhverfi when the sheep were put in the experiment. In
spite of this the health of the ewes was relatively good. One ewe and
four lambs died during the experiraental period and one lamb was found sick
and removed from the experiment. Three lambs got lost in the experiment.
In the Sölvaholt experiment the calves were healthy during the
experimental period.
In general the experimental livestock was in poorer condition when
put in the experiments than in previous years due to cool weather and poor
vegetation growth. In addition this delayed in some cases the onset of
the experiment causing the pastures where the livestock were stored before
