Abstract

The purpose of the study was to determine the effect of Mulberry leaf extract (MLE) supplementation in drinking water on growth performance and carcass percentage of broiler chickens. The research method is quantitative. The broilers were supplemented with MLE in drinking water for 28 days. The research consists of five treatments with four replications, T0 = drinking water (negative control), T1 = 0.05 g tetracycline antibiotics/liter of drinking water (positive control), T2 = 1 ml MLE/liter of drinking water, T3 = 3 ml MLE/liter of drinking water and T4 = 5 ml MLE/liter of drinking water. Research parameters include growth performance and carcass percentage. Data analysis was conducted using ANOVA, and it was followed by the Duncan test. The results of the study showed that supplementation of the extract in drinking water did not affect feed intake, water intake, non-carcass percentage, and abdominal fat, but affected the final weight, carcass percentage, and feed conversion ratio. The study concluded that the supplementation of MLE with a dose of 0.05 g/liter of drinking water increased final body weight, average daily gain, carcass percentage, and decreased feed conversion ratio of broilers.

Abstract

This study was aimed to perform phenotypic and genothypic characterization of Escherichia coli (E. coli), particularly VTEC strain isolated from cattle faeces. In this study, 25 E.coli isolated from faeces specimens and faeces base fertilizer of dairy and beef cattles were used. Examination were carried out using phenotypic and genothypic characterization which is specified for E coli VTEC strain. The result showed that 20 % samples of fresh faeces specimens were detected as VTEC strains and none of isolate was detected from faeces base fertilizer samples. From VTEC strains, could detect 16 % VT1 gene, 12 % VT2 genes and 8% of both. Detection on gene pyelonephritis-associated pilli (pap), S fimbrial adhesion (sfa), and afimbrial adhesion (afa) were found about 60%, 80% and 80%, respectively.

Abstract

Penelitian ini bertujuan mengidentifikasi dan karakterisasi Staphylococcus aureus (S. aureus) yang berasal dari kasus bumblefoot dan arthritis. Dalam penelitian ini digunakan 10 isolat S. aureus yang terdiri atas lima hasil isolasi asal kasus bumblefoot dan lima hasil isolasi asal kasus arthritis pada ayam broiler. Identifikasi S. aureus dilakukan melalui uji fermentasi manitol salt agar (MSA), pewarnaan Gram, uji koagulase, clumping factor, dan uji katalase. Karakterisasi fenotipe S. aureus yang dilakukan meliputi sifat hemolisis pada plat agar darah, sifathidrofobisitas, dan kemampuan hemaglutinasi. Hasil penelitian menunjukkan bahwa semua isolat S. aureus mampu memfermentasi MSA, positif uji koagulase, clumping factor, dan katalase. Staphylococcus aureus mampu menghemolisis plat agar darah dengan memperlihatkan sifat -hemolisin (80%), -hemolisin (10%), and -hemolisin (10%). Semua isolat S. aureus (100%) bersifat hidrofil dan mampu mengaglutinasi sel darah merah kelinci.

Abstract

Demand for chicken consumption in Indonesia tends to increase every year. Broiler chickens were slaughtered at short age than past years, recently about 4 to 6 weeks. Total of 28 to 42 day old broiler chicks were distributed to completely randomized design in factorial scheme (4,5 and 6 weeks old) and 2 (male and female). All of evaluated were live body weight (LBW), carcass weight (CW), and carcass percentage (CP). Analyzed used Two Way analysis of variane (ANOVA) using SPSS with 5 replication. Duncan Multiple Range Test (DMRT) to determine the differences among treatment means.  The result showed that live body weight had unsignificantly effect of sex but affect (P<0.05) to slaughter age (4, 5 and 6 weeks) it was 1460 g, 1881 g and 2310 g. The means of carcass weight with different sex of male and female had unsignificantly effect it was 1.283 g and 1.223, so do the carcass percentage was 69.43 % and 70.15%. This research can be concluded that difference sexing un affect to body weight (1.891 g), carcass weight (1.253 g) and carcass percentage (69.79%), but the female broiler get higher than male broiler. Thus slaughter age affect (P<0.05) to body weight, carcass weight and carcass percentage, at 4 weeks old was tend to decrease but increasily at 5 weeks and 6 weeks old. The best body weight, carcass weight and carcaas percentage at 5 weeks old, according to market demand.
