Abstract

The experiment was conducted to evaluate the influence of feed additive containing lactic acid bacteria (LAB) and Ganoderma lucidum (GL) on body weight gain (BWG), feed efficiency (FE), performance index (PI), antibody titer (AT) against Newcastle disease and histopathology of broilers. Bacteria used were Lactobacillus salivarius and Pediococcus pentosaceus, which were isolated from broiler's intestine. A number of 195 unsexed day old chicks (Cobb strain) were arranged in a completely randomized design and consisted of 5 treatments, each in 3 equal replicates. The treatments were as followed T0: control/without-feed additive, T1: 1% LAB (109 cfu g-1), T2: 1% GL, T3: 1% of LAB 109 cfu g-1 + GL (1:1), T4: commercial antibiotic. Data were analyzed using ANOVA and conti-nued to Duncan's multiple range test. The results showed that T2, T3, T4 treatments significantly improved (P < 0.05) BWG, FE and PI of broilers. Broilers fed T3 had the highest PI, followed by T4, T1, T2 and T0. Broilers fed T3 had the highest AT value followed by T0, T2, T4, and T1. Histopathology profile showed that broiler fed T3 had no lesion on liver and intestine compared to others. The result of this experiment indicated that additive containing 0.25% L. salivarius, 0.25% P. pentosaceus, and 0.5% G. lucidum was able to enhance broiler performance.

Abstract

An experiment was conducted to determine the efficacy of bio additive administration (a mixture of Lumbricus rubellus extract, Morinda citrifolia leaves extract and lactic acid bacteria), probiotic, and antibiotic to the performance and meat quality of broiler infected with Avian Pathogenic Escherichia coli (APEC). In this study, 140 Jumbo 747 unsexed one-day old chicks were distributed randomly into 20 units of cages, each filled with 7 broilers. Twenty cages were assigned into 5 treatment groups, each treatment in 4 equal replicates. The treatments were as follows: A= E. coli infection (positive control), B= E. coli infection + bio additive, C= E. coli infection + probiotic, D= E. coli infection + antibiotic, E= No E. coli infection (negative control). A commercial corn-soybean-based broiler diet was formulated as the basal diets. The experimental period was 35 d and at 21st d of age the broilers were infected with E. coli except the E treatment. The result showed that bio additive administration (B) increased the final body weight (1,659.52 g) and body weight gain (1,616.81 g) and resulted in less FCR (1.87) among other treatments. The lowest mortality rate was recorded in B treatment (3.57%) and D treatment (3.57%). Probiotic (C treatment) and antibiotic (D treatment) decreased (P < 0.05) meat pH and tenderness compared to other treatments. Meanwhile bio additive administration did not affect the meat quality (pH, cooking loss, water-holding capacity, tenderness, and fat) compared to positive and negative controls. The lowest meat cholesterol content was observed in B treatment (54.02 mg/100 g). It is concluded that bio additive administration on broiler infected with E. coli increased the broiler performance and decreased the meat cholesterol compared to other treatments.
