“…Similarly, Khan et al (36) reported higher weights of the thymus as a result of probiotic feed supplementation due to its effects on the immune system. Kumar et al (37) reported higher weight of bursa in treatment groups supplemented with probiotics compared to control and AGP supplemented groups. In the current study, the lymphoid organs had higher weights in the vitamin C supplemented group (B 2 ) compared to the control (B 1 ) and AGP (B 4 ) supplemented groups.…”

Newcastle disease (ND) is a highly contagious viral disease. This study was conducted to determine the antibody titer in Japanese quails following vaccination against ND and feed-supplementation with vitamin-C, probiotics and antibiotic-growth-promoters. Forty Japanese quails were equally grouped in four groups (A1 to A4) and were vaccinated by LaSota, B1, F and VG/GA strains, respectively, at the age of 10 days. Another forty Japenese quails were equally grouped in four groups (B1 to B4), were vaccinated with the vaccines of the previous groups that showed a higher effect, and were fed with mesh-feed (control-B1), supplemented with vitamin-C (B2), probiotics (B3), and antibiotic growth promoter (B4). Serum samples were obtained on 2, 4, 6, 8, 10 and 12 weeks of age and were subjected to a hemagglutination inhibition test. The mean antibody titer (Log2) had no significant difference between groups A1-A4. The highest titers were recorded in A4 (6.20±0.37) and A3 (6.00±0.71). The mean titer was significantly different among the groups at 4 weeks, but insignificant in the other weeks of the supplemented groups. A higher mean titer was found between 8 and 10 weeks in group B2 (7.40±0.60) and B3 (7.20±0.58). The relative weights (gm/kg) of the spleen, thymus and bursa were significantly higher in group B3 (1.947±0.109, 5.951±0.312 and 2.624±0.083, respectively). They had no significant correlation with antibody titer at 12 weeks. In conclusion, vitamin-C and probiotic supplemented feeds can boost up the antibody titer against ND in Japanese quail when given during VG/GA strain vaccination.
