| Abstract | ||
| Pictures, weights of internal organs and immune response to infectiousbursal disease(IBD vaccine) of broilers fed different levels of Boron (100mg, 200mg and 300mg/kg) in feedfrom 1 week to 4weeks. 150 broiler chicks (one day old) were randomly divided into five equalgroups (each group contain 30), as following: first group ,(G1) was received 100 mg/kg ofBoron, second group (G2) was received 200 mg/ kg of Boron, third group, (G3) wasreceived 300 mg/ kg of Boron and fourth group (G4) was not received Boron in feed Just take IBD vaccine and consider as control positive, (G5) was not received Boron in feed and consider as control negative , four groups only vaccinated with IBD vaccine at 10 and 18 daysold, Growth performance of the chicks (Body weight, weight gain and feed intake )were weekly determined, at the end of experiment weights of internal organs (,kidney, spleen and bursa of fabricius) were determined and Blood samples were collected tomeasured antibody titers (Ab)titers against IBD vaccine by ELISA test ,total protein and determined blood pictures(RBCs, PCV,WBCS,H/L ratio), The results of this study showed that body weight, weight gain, feed intake, , total protein, blood pictures and Ab titers were highly significant increase (p<0.01) in G2 ascompared to control group followed by G1 respectively in all weeks. Whereas theweights of internal organs (kidney, bursa of fabricius and spleen ) were significantincrease in G3, G2 and G1 respectively. In conclusion, the results indicated that 100mg/kg.feed,200mg.kg.feed levels of Boron supplemented diet of broiler chicken caused improvement of blood parameters growthperformance, there's no inhibition of the immunity response ofchickens against IBD vaccine. | ||
