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.

Abstract

The experiment was conducted to evaluate the effect of probiotic and organic mineral complex (POMC) administration on performance and meat quality of local sheep. In this study, 6 sheep with an average initial body weight of 12.67±0.81 kg were arranged in a completely randomized design with 2 treatments and 3 replications. The treatments were T0: basal diet (control) and T1: basal diet + POMC. The basal diet consisted of forage and concentrate (60:40) with dry matter of feed intake as much as 5% of body weight. Dose of POMC used in this study was 15 g/d/head. The POMC contained lactic acid bacteria, i.e. Lactobacillus sp. (1x108 cfu/g) and S. cereviseae incorporated with micromineral Co (2 ppm), Cu (100 ppm), Fe (2.5 ppm), I (110 ppm) and Mn (100 ppm). The experimental period lasted for 11 wk (1 wk for adaptation and 10 wk for data collection). Data were analyzed using t-Student statistical test to compare the treatments. The results showed that POMC administration did not affect the body weight gain (BWG) (7.46 kg) compared to control (7.13 kg) while concentrate consumption (26.9 kg) of POMC was lower than the control (28.6 kg). Meanwhile POMC administration did not affect the meat quality (pH, moisture, cooking loss and tenderness), whereas the meat cholesterol was lower (34.25 mg/100g) than the control (38.87 mg/100g). It is concluded that administration of probiotic lactic acid bacteria combined with organic minerals decreases concentrate consumption and thereby potentially increases the animals energy utilization efficiency. In addition, the treatment also decreases the meat cholesterol content of local sheep.
