Curd yield was lower in the infected halves than in
the uninfected ones. This phenomenon is directly related
to the finding of lower casein content and higher p-p
content in the milk, the latter being an indicator of casein
breakdown. These findings reveal the losses that are not
indicated by measurements of milk yield, and emphasize
the severity of the effects of subclinical mastitis on cheese
production through its effect on Yc. In addition to the
direct loss of curd, in terms of volume, as presented
above, Tc provides indirect evidence of poor milk quality
since it is common to determine milk-clotting activity
according to the rapidity with which the enzyme clots
milk under a set of specified conditions
