The findings of the present study highlight the economic
loss that can be attributed to IMI caused by CNS;
this was clearly demonstrated by using the half-udder
model. In goats, as in sheep, infection decreased Yc and
increased curd Tc, and these changes were reflected in
increased CN degradation, increased CN degradation
products (p-p), and decreased aCa
2+. However, the
higher CN content and higher PL activity in sheep than
in goats results in a higher output of CN degradation
products, including factors that down-regulate milk secretion.
This accounts for the stronger effect on milk
yield in sheep than in goats. This scenario suggests
that in terms of milk yield, sheep are more vulnerable
than goats to subclinical infections, though definite conclusions
should await the accumulation of additional
independent data. The trends in the responses of PA
and PL activities to SM are similar in goats and sheep.
The unusually high basal PA activity in goats results
in a lack of PLG in their milk. Consequently, our results
suggest that the PL system functions at a lower rate
in goats than in sheep and that its response to external
factors, such as infection, that augment its activity in
other species is more attenuated in goats.
