Taurine, a derived amino acid has been proven to play an important biological roles in enhancing bone strength and immune activities of broiler birds.

A total of 300 unsexed day-old arbor acre broiler birds were used for this research.

Antibody titre against NCDV and IBDV were determined according to standard procedures. The study lasted 42 days. Birds on 0.002% taurine had the highest antibody titre (128.38) against NCDV, while birds on the 0.006% taurine-supplemented-diet also portrayed a distinct (p<0.05) titre value (1029) against IBDV. Serum alkaline phosphatase and bone specific alkaline phosphatase (132.74 and 150.66) at the 42nd day were highest (p<0.05) for birds on 0.004 and 0.002% dietary taurine supplement respectively. The activity of serum tartrate resistant acid phosphatase (44.94) was notably highest (p<0.05) for birds on 0.008% taurine. Bone mineral contents showed that birds fed with 0.002% taurinesupplemented- diet had the highest percentage (p<0.05) of phosphorous (9.50), calcium (32.18) and phosphate (21.77) composition. Conclusively, inclusion of taurine as dietary supplement has proven useful not only in enhancing the birds’ immunity against NCDV an IBDV, but also in boosting bone mineral composition of meat type poultry birds.
