Value of Metabolizable Energy and Digestibility of Nutrient Concentrate from Fermented Shrimp Waste for Domestic Chickens

Metabolizable energy and nitrogen retention of local chickens fed rations containing fermented catfish waste

“…When compared to research [26], the level of feeding shrimp waste flour in broiler chicken rations as much as 100 grams/kg (10%) achieved the best energy availability of 5,467 MJ / kg or 1,305.77 kcal / kg dry matter base. In addition, results that are not too far shown from research [24] shrimp waste bioprocessing through gradual fermentation by Bacillus licheniformis followed by Lactobacillus sp, and Saccharomyces cerevisiae produced the best nutritional concentrate with a metabolizable energy value of free-range chicken 2,614 kcal / kg. At the same time, the research of Abun et al (2016), the effect of giving shrimp waste bioprocess products by three microbes Bacillus licheniformis, Lactobacillus sp., Saccharomyces cerevisiae with a bioprocessing time of two days in local chickens showed metabolizable energy of 2,613.90 kcal/kg.…”

“…Fermented products containing LBS microbes can have a positive impact because of the activity of microorganisms that can increase the absorption of nutrients in poultry's digestive tract. This is because LBS can complex compounds of proteins and fats into simpler amino acids and fatty acids by the opinion [24] that Saccharomyces cerevisiae is a yeast that produces amylase enzymes, lipases, proteases, and other enzymes that can decompose food substances in the digestive organs. Similarly, research conducted by [29] shows that fermentation of fish waste with Bacilus subtilis bacteria can increase the content of nutrients, including amino acids.…”

“…The effect of feeding shrimp waste bioprocess products by three microbes Bacillus licheniformis, Lactobacillus sp., and Saccharomyces cerevisiae, with a bioprocessing time of two days in local chickens showed metabolizable energy of 2,614 kcal/kg [23]. Bioprocessing shrimp waste through gradual fermentation by Bacillus licheniformis followed by Lactobacillus sp, and Saccharomyces cerevisiae produced the best nutrient concentrate with a protein digestibility value of 72.91% [24].…”
