Abstract

Fish waste (“ikan rucah”) is part of discarded fishing product, which is composed by non-foodcategorized fish (NFC-fish). Quality of NFC-fish meal that was made by dipping in extract of fermentedvegetable’s waste has been reported better than commercial fish meal, but the effect after storingremained in question. Experiment was conducted to study the effect of different time of storing onphysic-organoleptical, chemical and microbiological characteristics of the acidified NFC-fish meal thatwas made by dipped in extract of fermented vegetable’s waste (FVW-exctract). The NFC-Fish wassoaked in the FVW-exctract by the ratio 1:1 (w/v) for 4 hours, and then it was dripped out and dried. Thedried fish was ground passed through 20 mesh, kept into plastic bags and stored at the room temperature(23-25 °C and 70-80% RH) for 0, 1, 2 and 4 months. Physic-organoleptical, chemical and biologycalcharacteristics were parameters observed. Experiment was conducted by completely randomized design(CRD). Data were analysed by the GLM of SAS. Actual number of moisture, crude protein, extractether, and proteolytic bacteria of fish meal were significantly influenced by time of storing (P<0.05).Dipping NFC-fish in the FVW-exctract effectively maintain the physical characteristics, pH, moisture,crude protein, extract ether and the number of proteolytic bacteria of fish meal up to 2 months ofstorage. Dipping NFC-fish in the FVW-exctract provide better characteristics on physical, chemical andmicrobiologycal than the commercial fish meal at the same condition of storage.

Abstract

The Experiment was conducted to study effects of binder mineral addition to the hatchery waste based pelletprocessingon its proximate component and energy value. The study may be beneficial to emerge a new feed resource for local farm businesses. The hatchery wastes those comprised of 30% of egg shells, 60% of un-hatched eggs, and 10% of culled DOC were blended, and mixed with 10% of cassava cake meal(W/W), then mixed well with mineral adsorbent (bentonites or zeolites) at 0, 1, 2, 3, 4 and 5% (W/W). The mixture was conditioned at 80 ºC for 15 min, and extruded to make a pellet with 6 mm of diameter and 30 mm in length, and dried into warm air flow dryer. The moisture, crude protein (CP), ash, ether extract (EE), crude fiber (CF), apparent metabolizable energy (AME), true metabolizable energy (TME), metabolizability(MET) and nitrogen retention (NR) were observed in each pellet. Result of the experiment showed that moisture of pellet was decreased (P<0.05) by zeolites or bentonites addition. Even though the effect ofbinder mineral addition gave different patterns, concentrations of ash, crude protein, ether extract and crude fiber of pellet product were increased by increasing level of mineral adsorbent (P<0.05). Nutrient availability as was represented by AME, TME, MET, and NR were increased by zeolites and bentonites additions (P<0.05). In conclusion, supplementations of bentonites and zeolites in the hatchery waste based pelletcould improve its proximate component concentration and nutrient availability.

Abstract

An experiment was conducted to examine the influence of soaking time into extract solution ofSauerkraut on physic and microbial performances of acidified fish meal. Sauerkraut extract (LPS'ssollution) was made by fermentation of wastes vegetable market for 6 days. The LPS-extract was used toacidify " ikan rucah" by the method of dipping for 0, 4 and 8 hours. Changes in pH, the total number ofbacteria, fungi and proteolytic bacteria, moisture content, odor, colour and texture were parametersobserved. Results of experiment showed that total bacteria, fungi and proteolytic bacteria of acidifiedfish meal significantly influenced by soaking time (p <0.05). No significantly effect was shown to thephysically performance. LPS-extract in the soaking effectively reduced content of total bacteria, fungiand proteolytic's bacteria in fish meal.

Abstract

Lactic acid bacteria (LAB) is one of the natural microbe which widely used as fermentation agents.The purpose of this study was to examine the characteristics, stability and antimicrobial properties oflactic acid bacteria (Leuconostoc sp) isolated from broiler’s caecum during storage. This research wasconducted by the Complete Randomized Design with 4 treatments (time of storage: 0, 2, 4 dan 6 weeks)with 12 replications. Parameters observed were total number and stability properties of Leuconostoc spisolate which known as lactic acid bacteria. The results obtained total number of Leuconostoc sp isolatewere significantly (P<0.05) decreased from 8 x 107 to 1 x 103 Colony Forming Unit (CFU)/mL duringstorage. Stability properties of Leuconostoc sp isolate were not affected by the time of storage.Antimicrobial activity of Leuconostoc sp were significantly (P<0.05) decreased from 9.94 to 8.68, 7.23and 6.14 mm during storage at 2, 4 and 6 weeks.

Abstract

This study aimed to examine the effect of using maggot frass level inclusion in the diet on the performance, digestive organs, immune organs, and economic value of Muscovy Ducks. The study employed a completely randomized design with four treatments and five replications. The treatments used were: T0= 100% basal feed, T1= 80% basal feed + 20% maggot frass, T2= 60% basal feed + 40% maggot frass, and T3= 40% basal feed + 60% maggot frass. This study involved 300 Muscovy ducks aged 4 days, weighing 40.52 ± 4.81 gram/bird, and spanning a rearing period of 8 weeks. The obtained data was subjected to analysis of variance, followed by Duncan’s test (p<0.05) for significance. The results showed that the increase in body weight, final weight, IOFDC, N retention, and carcass percentage decreased along with increasing maggot frass content. There was an increase in feed consumption, AME, TME, and crude fiber digestibility when giving maggot frass. There is a tendency for performance to decrease as the percentage of maggot frass in duck feed increases, but maggot frass can still be used at a percentage of 40%. Based on the study’s findings, the use of maggot frass up to 40% can reduce feed operational costs and positively affect the IOFDC value.
