Abstract


This experiment was conducted on 20 adult Ossimi rams (1–2 years
old and averaged 44–48 kg live body weight) to evaluate the dietary
supplementation of ZAD compound (patent product contains cellulases,
xylanases, protease and α amylase) to improve overall nutritional status
and consequently will improve semen quality characteristics in sheep.
Rams were randomly divided into 2 equal groups (10 for each). The
first group (G1) served as control and was fed rice straw without supplementation, while the second group (G2) was fed rice straw treated with ZAD compound. All rams received concentrate feed mixture (CFM) to
cover 100% of their maintenance energy. Forage and CFM were adjusted
biweekly according to live body weight changes and roughage to CFM
ratio was 60:40 during the experimental period. The experimental feeding period lasted for 8 mo, the first 2 mo were a preliminary period and
the other 6 mo were the main period of semen collection (once a week).
General Linear Model (GLM) procedure of SAS, ANOVA and LSD test
were used for statistical analysis. Results revealed that overall mean of
semen characteristics were 0.54 vs. 1.21 mL, 77.81 vs. 85.18%, 2.15
vs. 2.85 × 109/mL, 75.90 vs. 78.05%, 12.10 vs. 9.68% and 5.20 vs. 5.91
for ejaculate volume, advanced motility, sperm cell concentration, live
sperm, abnormal sperm and pH value of semen for control and treated
group, respectively. Body weight changes were promoted (P < 0.05) by
treatment as compared with the control group. Blood plasma concentrations of total protein, albumin and globulin were higher (P < 0.05) in
G2 (8.22, 2.82 and 5.40 g/dL) as compared with those corresponding
values in G1 (5.59, 2.18 and 3.41 g/dL, respectively). Blood plasma
levels of thyroxine (T4) hormone showed a tendency of increases in
G2 than in G1 (5.21 vs. 4.65 ng/dL). Similarly, triiodothyronine (T3)
and testosterone concentrations were significantly higher in G2 than
in G1 (164.8 vs. 138.3 ng/mL). Results of the present study indicated
that feeding rams on ration containing ZAD compound had a beneficial
effect on their semen quality characteristics, including sperm motility
%, sperm cell concentration (× 109/mL), live sperm% and normal sperm
% comparing with the control group.
