control diet.

Improved colostrum quality
Research shows ewes fed zinc from ZPM resulted in an 8%
increase in IgG concentration compared to ewes fed the
control diet. An average increase in IgG content of 23.8%
across three studies has also been shown in dairy cows
fed ZPM. In addition, a 10% improvement in percentage of
lambs weaned was achieved in the ZPM group, compared
to those in the control group.
No added zinc.
Zinc from ZPM sources provided 80 mg Zn per head per day.

Lambs born to ewes fed zinc from ZPM had a higher
(P<0.01) average daily gain (ADG) from day 0 to 69 than
lambs born to ewes fed the control diet. Research shows
early lamb growth can be influenced by feeding ewes a
more bioavailable source of zinc during late gestation and
through weaning.
