Analysis of the sustainability level of using immunoglobulin y (IgY) as antibiotic substitute

Broiler chickens are the highest source to fulfill animal protein consumption of the Indonesian people. The population of this type of chicken is very high because it does not require a large area in maintenance, has fast growth and good feed efficiency compared to other types of broiler poultry. Broiler farms generally use antibiotics as feed additives to trigger growth, increase body weight and improve the efficiency of food converted into meat. Antibiotics are also used for disease prevention and treatment, especially by commercial chicken farmers. Antibiotics used in livestock production account for about two-thirds of global antibiotic sales and consumption. The unwise use of antibiotics also increases the occurrence of antimicrobial resistance, especially in bacteria. This research goals to analyze the sustainability of using IgY affixes as a substitute for antibiotics in chicken feed. The results of the analysis are grouped based on the value of the sustainability level. The results of Multi Dimensional Scaling (MDS) analysis using the RAPFISH (Rapid Appraisal for Fisheries) analysis tool showed that the level of sustainability of IgY use was 66.49% with a quite sustainable category.
