ABSTRACT
AL-Nrkelge
IH, Al-Deri AH., Effect of dietary zinc with or without exogenous fibrolytic enzyme on serum protein, urea, glucose and
cholesterol in ram lambs, 22 (9):851-855, 2018. Four groups of 3 to 4 month old 4 ram
lambs each weighing 24-28Kg were supplemented 0.3g zinc amino acid complex with
or without 8g exogenous fibrolytic enzyme daily for 10
weeks. Controls (2) were lambs fed basal diet without supplements and data from
day 0 in those given supplement. All groups were fed concentrate pellets adjusted
to 3% of body weight grazed daily 3 hours as one herd. Lambs were offered hay
and green roughage with water ad libitum
when not grazing. Jugular blood was taken at Day 0 and every 14 days for 10
weeks for hematology and serum urea, protein, glucose and cholesterol. Compared
with both controls (P< 0.05), albumin increased 35-49% by days 56-70 and
urea 9-27% by day 42 to 70. Compared with non-supplemented controls, serum cholesterol
was 5-16% lower (P < 0.05) at days 42-70. We found no differences in serum
values between the different supplements.
