Immune response with some blood parameters of broiler chicks fed on rations contained different levels of zinc and folic acid

Abstract EN

The research was conducted to investigate the effect of Zinc and Folic Acid on Immune status as well as some blood parameters of broiler chickens.

Atotal number of 400, one day old broiler chicks ( Ross 308 ) were distributed on 8 treatments, and fed on rations contained different levels of Zinc and Folic acid with their combination.

Chicks were raised in to a semi closed house in the poultry farm which belongs to animal production Techniques in the Technical Colloge Al-Mussayab during the period which extended from the 2nd of march till the 12th of april 2018.

Results revealed a highly significant surpass (p<0.

01) of antibody titer against Newcastle disease, Infectious Bursal Disease and Infections Bronchitis in broilers supplemented with Zinc or combination of Zinc with folic acid.

Moreover there was a significant amelioration (p<0.

05) of Paced Cell volume with highly significant (p<0.

01) amelioration of Heterophil / lymphocyte index as well as a highly significant elevation (p<0.

01) of total plasma protein with highly significant(p<0.

01) reduction of glucose, cholesterol and Triglycerides in the plasma.
