Extracted pearl grass effect on broiler carcass kept on Escherichia coli - Sprayed litter

Abstract

An experiment was conducted to determine the effect of hexane and acetic ethyl extracted pearl grass as feed additive in the ration on carcass of broiler chickens where the litter was sprayed by Escherichia coli. The experiment was assigned to Completely Randomized Design with 5 treatments and 4 replications. The treatments were level of pearl grass extract added into the ration; 0 (R0, control), 0.8 (R1), 1.6 (R2), 2.4 (R3) dan 3.2 (R4) gram per kilogram ration. After 3 weeks of age, litters were sprayed by Escherichia coli as much as 106 CFU/100 ml liquid agar. Then, chickens were kept until 6 weeks of age. Result showed that there was no significant different among treatments groups on chicken carcass and there was no any adverse effect on liver and intestines. It is concluded that extracted pearl grass could be utilized as natural feed additive source to produce carcass of broiler chicken where their litter was sprayed by E. coli bacteria.
