EFFECT OF PAPAYA (Carica papaya) LEAF JUICE ON PRODUCTION PERFORMANCE AND MICROBIAL LOAD OF SONALI CHICKEN

Abstract

A study was undertaken to investigate the effect of papaya leaf juice on growth performance and bacterial load in faeces of sonali chicken. A total of one hundred eighty (180) vigorous 28 days sonali chicks were randomly divided into five treatment groups namely T0 (Control), T1 (growth promoter (Amino solve) @1ml/1L drinking water), T2 (10% papaya leaf juice in drinking water), T3 (20% papaya leaf juice in drinking water) and T4 (5% dried leaf in feed) having three replication in each treatment group. Data on live weight and feed intake were collected and bacterial load in faeces were recorded and analyzed by ANOVA using the SPSS, version 22.0 software. Total feed intake were nonsignificant (P>0.05) among the treatment groups but final live weight, live weight gain and FCR were significantly differed among the treatment groups. Total feed intake (gm/bird) and live weight (gm/bird) at 5 th , 6 th , 7 th , 8 th week were non-significantly (P>0.05) differed among the treatment groups but live weight (gm/bird) at 9 th and 10th week and FCR were significantly (P<0.05) differed among the treatment groups. The final (10th week) average body weight (gm) was significantly (P<0.05) higher T1 (605.00±7.64) and T2 (601.88±5.82), followed by T3 (572.22±8.92), T4 (569.31±6.38) and T0 (539.33±14.85), respectively. The best and lowest FCR was found in T2 (2.63±0.04) and highest FCR was in T0 (2.98±0.07) whereas in T1, T3, and T4 was 2.63±0.04, 2.79±0.05 and 2.80±0.04 respectively. The load of Salmonella sp. and E. coli was significantly (P<0.05) lower at increasing concentration of papaya leaf juice compared to control. The present study concludes that supplementation of 10% papaya leaf juice in drinking water can be used as alternative to commercial growth promoter for the production of sonali chicken.
