Abstract:
The broiler performance can be influenced by optimizing the in-house environment and the negative effects of litter on the environment of the poultry can be minimized by the utilization of nanoparticles to reduce ammonia production. For this purpose, this study was performed for 42 days, including 540-day-old broiler birds. The birds were randomly divided into six groups A-E and X, while the groups C, D and E were further divided into four sub-groups at 15th day. First two groups were kept as a positive and negative control. Birds were treated with combination of three types of nanoparticles, i.e., alum, zinc oxide and copper oxide in combination along with starch as an excipient powder. Nanoparticles were sprayed on litter material to kill the litter microbes and reduce the ammonia emission. Ammonia was produced by maintaining wet litter conditions by sprinkling water at the rate of 250ml per day for first week of treatment trial. Ammonia, Temperature, moisture, humidity, litter pH were recorded daily throughout the experiment. Air and litter microbial count were recorded on weekly basis. Birds from each group were slaughtered at the 22nd and 42nd day of the final age of the birds. The results showed that positive control group showed significantly (P<0.05) increased levels of ammonia, humidity, litter moisture, litter pH level, air and litter microbial count as compared to the treatment groups. However, the combination of lower dose nanoparticles of copper oxide, zinc oxide and alum showed better effect in improving the in-house environment as compared to the negative control group. The study showed that Copper oxide, zinc oxide and alum nanoparticles can be used as possible substitute to overcome the in-house environment problems in broiler birds. However, further studies are suggested at commercial setting to see the real impact of these nanoparticles.
