Abstract:
To investigate the effects of dietary supplementation with industrial vinegar (IV) and waste date vinegar (WDV) on growth performance, intestinal morphology, and immune response of broilers, five hundred Ross ۳۰۸ chickens were randomly divided into ۵۰ cages in a ۴۲-day breeding period. The experiment consisted of ten treatments with five replications in each treatment including; control ۱ (standard feed without WDV or IV), control ۲ (control ۱ + ۲% water into the feed), ۱, ۲, and ۳% of WDV and ۲% industrial vinegar (IV) into the feed and ۰.۵, ۱, and ۱.۵% of WDV and ۱% industrial vinegar (IV) into the water. One chicken from each replicate was slaughtered on days ۲۴ and ۴۲ to investigate gastrointestinal tissue growth as well as intestinal morphology. The results showed that growth performance was not affected by treatments in any period. The height and width of the villus in the treatments containing ۱% of WDV into the water and ۲% of WDV into the feed increased with time compared to the control treatments. On day ۴۲ of the experiment, the crypt depth was also higher in the treatment containing ۱% of WDV into the feed compared to the other treatments. The ileal coliforms were also affected by WDV addition into the feed at ۴۲ days of age compared to other groups (P < ۰.۰۵). The highest amount of IgM and IgG were found to levels of ۲% and ۱% of WDV into the diet, respectively (P < ۰.۰۵). However, SRBC, ND titter was not affected by treatments. Also, no difference was found between industrial vinegar in water or feed in most of the studied parameters. The results of this study showed that supplementation of the diet with WDV had a positive effect on intestinal morphology and immune system of broilers compared to industrial vinegar.
