Comparative Effect ofLactobacillus caseiand a Commercial Mangosteen Dietary Supplement on Body Weight Gain and Antibody Response to Newcastle Disease Virus Vaccine in Fighting Roosters

Abstract

The aim of the present study was to compare the effect of Lactobacillus casei and a commercial mixed combination of fruit juice that included Garcinia mangostana fruit extract on body weight gain from 7 to 90 days of age, on the antibody response 23 days after vaccination against Newcastle disease virus (NDV), and on the mortality in fighting roosters. Fifty-four 7-day-old birds were randomly distributed into three groups (treated with L. casei, G. mangostana, and saline solution [LC, GM, and SS groups, respectively]) of 18 animals each; all birds were orally treated daily. At 60 and 90 days, the LC group showed the highest body weight gain compared with the other two groups (P<.01). The mean levels of antibody to NDV were significantly higher in the GM group compared with the LC and SS groups (P<.05). Throughout the study the percentages of mortality were 5.55%, 0%, and 22.22% for the LC, GM, and SS groups, respectively. The results indicate that L. casei and the commercial mangosteen dietary supplement intake, compared with the control group, induce beneficial effects in fighting roosters--L. casei on weight gain and the commercial mixed combination of fruit juice with G. mangostana fruit extract on humoral immune response--and both showed none or very low mortality.

“…108 The study showed enhancement in birds' body weight and feed conversion rate; however, the humeral immune response to NDV vaccination was similar to that of untreated, vaccinated groups. Similar results were later revealed by Bautista-Garfias et al, 109 who studied the effect of oral administration of L. casei (ATCC7469 strain) on the humeral immune response to NDV vaccination and production performance in fighting roosters. Blood anti-NDV antibody levels in L. casei-treated group were comparable to those of the vaccine control birds.…”

“…On the other hand, the natural mortality rate and body weight gain were significantly improved in the probiotic-treated group, compared with the untreated one. 109 The use of two (cecal and jejunal) bacterial isolates of L. reuteri PIA16 strain in feed, either alone or with a prebiotic (mannan oligosaccharide), demonstrated substantially enhanced humoral immune response to NDV vaccine in broiler chickens. The cell-mediated immune response; however, remained largely unaffected throughout the course of the experimental period.…”
