Serum lipid assay
The effects of treatments on triglyceride,
cholesterol, high and low density lipoproteins
are illustrated in Table 4. The highest and
lowest serum cholesterol and triglyceride
levels were attained by virginiamycin and
Sangrovit
® groups, respectively (p0.05).
Moreover, No significant differences were
observed in coliforms bacteria counts and
lactic acid bacteria in cecum at 42 day of age
(p>0.05).
Intestinal morphology
The effect of different treatments on
intestinal morphology characteristics are
presented at Table 6. Dietary treatment
affected villous characteristics at different age.
The highest and lowest villous height in
duodenum and jejunum were attained by
Primalac
® and control at 21 and 42 days of
age, respectively (p0.05). In addition, no
significant differences were observed between
treatments in the crypt depth in duodenum,
jejunum and ileum at 21 and 42 days of age
(p>0.05). Greatest villi height: crypt depths in
jejunum were obtained by Primalac
® at 21
days of age (p0.05). Greatest villi
height: crypt depth in Duodenum and jejunum
were obtained by Primalac
® (p0.05).
