Abstract:

A six week biological experiment was conducted to evaluate different levels and sources of zinc in terms of broiler performance and their immunity under heat stress. A total of 384 broiler chicks were divided into 48 groups with 8 birds in each. Following a 3x4 factorial design 12 dietary treatments were formulated employing three levels of zinc (40, 60, and 80 ppm) from four different sources viz. inorganic (IZ), organic (OZ), green nano (GNZ), and market nano zinc (MNZ) and each treatment was allocated four groups. The significantly better body weight gain (BWG), feed intake (FI) and feed conversion ratio (FCR) was observed at 80 ppm Zn followed by 60 ppm Zn as compared to 40 ppm Zn. The BWG and FCR was (P<0.05) better in birds fed GNZ and poor in birds fed IO, whereas, birds fed MNZ and OZ showed intermediate performance. The overall feed intake of birds was lower (P<0.05) in GNZ and MNZ than IZ or OZ. The results of immune response revealed significantly better (P<0.05) immunity (PHAP and SRBC values)and higher (P<0.05) relative weight of immune organs (thymus, bursa, spleen) of birds fed 80 ppm Zn followed by 60 ppm Zn and then40 ppm Zn. Among the Zn sources GNZ resulted in higher immunity and organ weights in birds followed by MNZ and lower values were observed in birds fed IZ. The HL ratio in birds fed 80 mg Zn/kg diet was significantly (P<0.01) lower as compared to other two levels which were statistically similar to each other. Among the organic sources GNZ resulted in significantly (P<0.01) higher HL ratio followed by MNZ as compared to IZ and OZ which did not differ significantly from each other. Based on the results it was concluded that 80 ppm GNZ results in better performance and immunity of broiler chicken.
