ABSTRACT
Broilers do not perform to their genetic potential in a stressful and diseased condition as concerned with poor bedding materials, high ammonia production from litter, and so on. The maximum ammonia production from litter depends on factors like moisture (%), pH, total nitrogen (%) of litter, and temperature of broiler houses. Carbonized Rice Husk (CRH) is a good poultry bedding material that consists of carbon and SiO2 which interestingly enhance ammonia adsorption. Keeping the above fact, this study was conducted to reduce ammonia reducing immunosuppression that manages susceptibility of E. coli. When the maximum level of ammonia was produced i.e., on day 34, intra-nasal administration of E. coli of strain χ7122 (serotype 078: K80:H9) at pathogenicity amount (9.4 x 105 cfu E. coli per bird) was done and morbidity and mortality rate was also recorded. The significantly minimum ammonia (ppm) was recorded in CRH (30.53±0.77); however, the maximum ammonia (ppm) was recorded in RH (49.78±0.42) with that compared to SD (33.42±0.25) and RS (43.22±0.56). Similarly, the mortality rate due to colisepticemia was recorded minimum in CRH (68.75%), however, the maximum was recorded in RH (86.25%) with that of compared to SD (70.00%) and RS (77.50%). It showed that CRH adsorbs ammonia produced in poultry houses reducing the immunosuppression managing susceptibility of E. coli. This proves CRH as the best poultry bedding material for the rearing of broiler chickens for better production.
