Protein Digestibility Capability of Nile tilapia (Oreochromis niloticus) Fed on Local Feed, Ethiopia | Chapter 2 | Innovations in Biological Science Vol. 5

 

The nutritional value of a feedstuff isn’t only on its chemical composition; however, it also depends on the nutrient-absorbing capacity of fish. Dietary markers must have no toxic effects, cannot be lost in digestion, cannot add considerable mass, and must be easily and equally mixed into feed. There are different types of dietary markers like ash, titanium dioxide (TiO2), and chromium oxide (Cr2O3). Most of the time chromic oxide was used in digestion trials with sheep, horses, cattle, pigs, fish, and humans. The experiment was conducted using 180 Oreochromis niloticus population with weights of 28.2 to 28.4 g, distributed in experimental randomized blocks design with five treatments and triplicates per treatment. Digestibility was estimated by the indirect method using chromic oxide at the concentration of 0.50 % of the diet as a marker. The apparent and true digestibility of the protein was estimated for noug cake, 87.1 and 89.1%; wheat bran 74.3 and 78.7%; soybean meal 88.3 and 90.0%; brewery waste 65.4 and 67.8%; fish meal 85.5 and 87.0%, respectively in siphoning technique. Similar (P > 0.05) results were observed in striping and siphoning methods in all experimental ingredients. This is the first report on protein digestibility status determined for O. niloticus in Ethiopia. This information provides an important basis for further investigation of single or mixed ingredients diet preparation or substitutions for evaluation of nutrient requirements of O. niloticus, to maximize performance and to minimize production costs and waste production. Soybean, noug cake, and fish meal had better (P < 0.05) crude protein digestible by O. niloticus than wheat bran and brewery waste. Brewery waste was the lowest digestible by O. niloticus. The fish that were consumed from brewery waste showed the lowest growth performance, which was also consistent with the ingredient's crude protein digestibility status. This suggests that O. niloticus has difficulty digesting brewery waste.

Reporting a Case Analysis of Gaea Company - Extra Virgin Olive Oil | Chapter 3 | Insights into Economics and Management Vol. 8

 Without a question, the olive oil industry is a conventional industry that has seen many breakthroughs in recent years as many companies attempt to merge traditional methods used in previous years with advances that have resulted from rapid technological development. The historical history of the Gaea Business, which is the main focus of this report, the product description, and the major competition of this brand will be discussed in this paper in order to create an integrated marketing strategy that will include the company's goals, target segments, and a purposed value proposition for it. Following that, the marketing technique used by the company will be examined in light of the commodity, place, price, and promotion. With this information, the product's current marketing strategy will be analysed, and suggestions will be made that could be beneficial to the company's growth, often using best practises in marketing management as a benchmark. While there are many things Gaea should rethink in order to achieve its lofty objectives, the principles that drive its strategy ensure that Gaea has a bright future in the long run.

Critical Study on Immunodetection of Porcine Red Blood Cell Containing Food Ingredients Using a Porcine-Hemoglobin-Specific Monoclonal Antibody |Chapter 11 | Current Research in Agricultural and Food Science Vol.1

Monoclonal antibody (mAb) 24C12 has been found to bind to a 12 kDa antigenic protein in the red
blood cell (RBC) of porcine blood. The purpose of this study was to determine the identity of this 12
kDa protein and consequently examine its potential as a marker for monitoring porcine RBCcontaining ingredients (PRBCIs) in foods. Proteomic techniques identified the 12 kDa antigenic
protein to be a monomer of the tetrameric hemoglobin molecule. Further heat-processing of spraydried PRBCIs diminishes its detectability. Whereas mAb 24C12-based indirect enzyme-linked
immunosorbent assay (iELISA) could detect 1% (v/v) or less of PRBCIs in raw and cooked ground
meats (beef, pork and chicken), the detection limits were 3 to 30 times higher for spiked cooked beef
and pork. The assay is effective for monitoring the presence of PRBCIs in foods to protect the billions
of people that avoid consuming blood. In situations where these PRBCIs are present as ingredients in
foods that have undergone further heat processing, the assay, however, may not be as sensitive
depending on the types of sample matrix, types of PRBCIs and the level of inclusion.
