Effects of varying levels of diatomaceous earth on performance and serum cholesterol levels in Broiler Chickens
MetadataShow full item record
The effect of inclusion of different levels of diatomaceous earth on performance of broiler chickens was investigated. The variables being investigated on were weight gains, feed conversion ratio, feed intake and cholesterol levels. The experiment comprised of 99 day old broiler chicks which were randomly allotted to three different dietary treatments containing diatomaceous earth. The control had 0% DE (Tl), and two different levels of inclusion of DE 2% (T2) and 3% (T3). The control birds were fed a diet without diatomaceous earth. The feed given was weighed on a daily basis and feed intake was recorded daily. The chickens were weighed every week and weights were recorded, cholesterol levels were analysed at the end of the experiment (day 42). There were significant differences in weight gains among treatments, with those fed on 3% recording higher weight gains. There were no significant differences in feed intake between 0% and 2%, but a significant difference was observed between 3% and the other two treatments (0% and 2%). There were no significant differences in FCR between the control and 2%. Significant differences were observed between the control and 3%. There were no significant differences in cholesterol levels between 0% and 3%, significant differences were observed between the control and 2%. The birds fed on 3% DE recorded the highest mean value (103.28 mg/dl) and those fed on 2% recorded a lower mean value (77.48 mg/ dl). Diatomaceous earth increases weight gains, improves feed efficiency and feed conversion in broiler chickens.
