Abstract

The aim of this research was to study the use of earthworm meal (TCT) L. rubellus as anti pullorum agent in poultry feed additive (IP). The antibacterial activity of TCT against Salmonella pullorum was examined using diffusion agar method at each of the following concentrations: 0, 25, 50, 75 and 100% (w/v) in 100 µL DMSO. In vivo test was conducted using 80 broiler chicken and were infected by S. pullorum with treatments of: IP0: IP contained 0% TCT, IP1: IP contained 25% TCT, IP2: IP contained 50% TCT, IP3: IP contained 75% TCT and IP4: IP contained 100% TCT. Each treatment was replicated 4 times with 4 chicks each. Feed additive was periodically fed to broiler during 7 days before and 10 days after infection. Anti-pullorum activities were evaluated using serology test, isolation and biochemical identification of S. pullorum. The results showed that 75% TCT was optimum to inhibit S. pullorum in vitro. The isolation and identification of S. pullorum results showed that 0 out of 8 (0%) broilers treated with IP4 was not infected by S. pullorum whereas 1 out of 2 (50%) broilers treated with IP0 were infected by S. pullorum. The reduction of S. pullorum prevalence as followed by increasing TCT in feed additive. In conclusion, TCT as poultry feed additive could inhibit S. pullorum infection.

Abstract

This research was conducted to enhance the bacterial growth inhibition of E. coli by using earthworm (Lumbricus rubellus) meal (TCT) which was added with chitosan and its effect on the retained protein in broilers. Inhibition of E. coli growth was tested using dilution method on the nutrient broth by additional 2% TCT combined with 0, 0.5, 1.0 and 1.5% chitosan. Retained protein was measured using broiler fed diet containing 2% TCT (w/w) and added by chitosan 0, 0.5, 1.0 and 1.50% of TCT (w/w). The numbers of 15 broilers Cobb strain 35 days old were arranged on Completely Randomized Design (CRD). Results showed inhibition of E. coli was increased using TCT mixed chitosan. The highest inhibition to E. coli growth obtained from TCT + 0.5% chitosan. Retained protein tended to increase up to 1% (w/w) chitosan. Otherwise, chitosan level more than 1% could reduce protein retention. It is concluded that use of 1% chitosan increased TCT capability to inhibit E. coli and protein retention in the broilers.

Abstract

Fungi contamination was a serious problem on feed industry in Indonesia. Mycotoxin was produced by contaminated fungi could decrease feed quality and it accumulation on animal caused immunosuppressive and mortality effect. The application of biological agent such as antifungal microbe was a promising solution and to be important for futher study. The objective of this research was to select lactic acid bacteria (LAB) with antifungal activity against mycotoxin producing fungi. Lactic acid bacteria were isolated from oil palm frond (OPF) silage, poultry and ruminant digestive tracts (cattle and goat). Antifungal activities of LAB was conducted by using overlay method and paper disc diffusion method of the cell free supernatant against   FNCC 6002,   FNCC 6033 and FNCC 6111. The result showed that LAB strain PDS2 from OPF silage had the highestKeywords: Animal, lactic acid bacteria, fungi, mycotoxin, oil palm frond silage ABSTRAKKontaminasi jamur dalam bahan pakan masih menjadi masalah dalam industri ternak di Indonesia.

Abstract

The objective of this study was to determine the inhibition ability of the earthworm (L. rubellus) extract (ECT), dried earthworm extract (ECT-k), and granule earthworm extract (ECT-g) as poultry feed additive against some pathogenic bacteria. Antibacterial activity was performed using diffusion method against Escherichia coli, Salmonella pullorum, Pseudomonas aeruginosa, and Staphylococcus aureus  in vitro. In the present study, the concentrations of ECT, ECT-k, and ECT-g in nutrient broth (NB) media tested were consisted of treatments A: 0%, B: 0.26%, C: 0.52%, D: 0.78% and E: 1.04% (g/vol) respectively. The results of the in vitro study showed that started from ECT level 0.26% inhibited (P <0.05) growth of P. aeruginosa and S. aureus, while ECT level 0.52% inhibited (P <0.05) E. coli and S. pullorum which proportional to the increased in concentration. ECT-k level 0.26% inhibited (P <0.05) growth of E. coli and S. aureus, while ECT-k level 0.52% inhibited (P <0.05) P. aeruginosa, and ECT-k level 1.04% inhibited (P<0.05) growth of S. pullorum. ECT-g level 0.26% inhibited (P <0.05) growth of S. pulorum, while ECT-g level 0.52% inhibited (P <0.05) S. aureus and ECT-g level 1.04% inhibited (P<0.05) growth of P. aeruginosa. There were no antibacterial action (P>0.05) of ECT and ECT-t against S. pullorum. Diameter of inhibition zone for 24 hours showed that S. aureus was the most sensitive bacterium to ECT and ECT-k, and S. pullorum was the most sensitive bacterium to ECT-g.

Abstract

Antibiotics in poultry were widely used as growth promotor and anti-infective. When antibiotics were used continuously for long periods, it caused microbial resistance. Various attempts were made to replace antibiotics along with the increasing of trend towards demand for healthy, safe and free from harmful residues of livestock products. One of them was application of earthworm which contains high protein and complete amino acids. Earthworms were extracted into water extract form by decoct method. Water extract form had some weaknesses. It was necessary to formulate into a solid dosage form which was more stable, reproducible, and practical. The selected formulation was encapsulation by spray drying method. Quality control of feed additives can be seen from biological value. Biological value correlated positively with amino acids equilibrium or Essential Amino Acid Index (EAAI). The result showed that earthworm extract had both essential and non-essential amino acids higher than earthworm meal and encapsulated earthworm extract. The highest essential amino acid in earthworm meal was isoleucine (3.14%), in earthworm extract was lysine (8.16%), and in encapsulated earthworm extract was leucine (1.71%). The highest non-essential amino acids in earthworm meal and encapsulation of earthworm extract were glutamic acid, respectively 7.67% and 1.87%, while the earthworm extracts was serine (14.52%). The high value of IAAE in earthworm extract showed that the extraction method resulted better amino acid balance (69.87%) than earthworm meal (58.67%). While the value IAAE of encapsulated earthworm extract showed that levels of essential amino acid balance was lower (16.05%) than the earthworm meal (69.87%) and the earthworm extract (58.67%).
