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.
