Abstract | To investigate the effects of supplementing drinkable water with waste date’s vinegar (WDV) on the growth performance and digestive tract of broilers, two hundred 1-day-old broilers (Ross 308) were used. Chicks were randomly allocated to 5 experimental groups including supplementing 0 (control), 0.5, 1, and 1.5 % of WDV and 1 % industrial vinegar (IV) into drinkable water. Broilers body weight and food consumptions were measured at the trial’s beginning and days 10, 21, 35 and 42 of experimental period. Moreover, one chick from every replicate was killed at days 21 and 42 to measure development of digestive tissues and morphology and microbiology of small intestine and evaluate the humoral immune responses (anti-SRBC antibody, IgG and IgM). Results showed that although the periodic body weight gain increased in all vinegar treatments compared to control (P<0.05), feed intake and feed conversion ratio were not affected by adding vinegar into water. Villus height was higher by use of 1% WDV compared to control and IV (P<0.05), but crypt depth was not different across groups. Also, ileum microbiota and humoral immune responses were not affected by treatments. Results indicated that supplementing drinking water with WDV and IV had positive effects on growth performance and use of 1% WDV developed histomorphology of jejunum in broilers.
