Abstract

Evaluation  of  metabolically  energy  of  three  agricultural  by-products  has  been  conducted  on  laying  hens.  The purpose of study was to calculate and to compare the energy values of onion hay, tofu waste and bananas skin. Twelve laying hens were randomly allocated to one out of three types of feeds.  About 50 g of powder form of feeds were forced fed to the experimental hens.  The results indicate that the gross energy varied within the tested feeds. The highest values of apparent metabolically energy (AME) and true metabolically energy (TME) were achieved by tofu waste, while the energy (AME and TME) values of onion hay were higher than those values in bananas skin. The values of TME were 10.04, 11.88 and 9.58 MJ/kg for onion hay, tofu waste and bananas skin, respectively.  It is concluded that the by-product feeds are still having metabolically energy as feeds sources for raising chickens, particularly laying hen.

Abstract

High total plate count (TPC) and the presence of Salmonella spp. in food products can cause health problems for consumers. De-boned milkfish products are popular with consumers in Palu City, Central Sulawesi, Indonesia, but there is a lack of data on their safety. Therefore, this study aimed to investigate TPC levels and detect contamination by Salmonella spp. in these products. Samples of fresh and processed milkfish were collected from two de-boned milkfish processing sites: the Technical Implementation Unit for the Application of Fishery Product Quality Control (TIU-AQFP) and the Melona Micro, Small and Medium Enterprise (MSME) Group in Palu City. Microbiological assays included counting the number of bacterial colonies (TPC) as well as the isolation and identification of Salmonella spp. through biochemical tests. The study applied a completely randomized factorial design with three replicates per site and per product (12 experimental units). De-boning had a significant (P0.05) effect on TPC (1.26×103 to 2.20×103 CFU/g for de-boned milkfish compared to 4.28×103 to 2.94×104 CFU/g for fresh unprocessed milkfish). However, the types of bacteria identified in fresh and de-boned milkfish, including Klebsiella, Enterobacter and Citrobacter, were present at non-pathogenic levels. No Salmonella spp. contamination was found in the test samples. These results indicate that de-boned milkfish products from the TIU-AQFP and Melona MSME Group in Palu City are safe and suitable for human consumption.Keywords:Bone-free milkfishBacterial contaminationPathogen assayFish processingFood safety
