CHICKEN SLAUGHTERHOUSE WASTE UTILIZATION (CHICKEN FEATHER MEAL TREATED) AS A SOURCE OF PROTEIN ANIMAL FEED INGREDIENTS IN BROILER CHICKENS

摘要

Waste of chicken slaughterhouse industries is one of the areas of live stock waste. The waste from this the industries contributes to environment damage. This problem is a consequence of the process of decomposition by bacterial. Decay by bacterial easily occur due to the high organic content of the waste, such as protein content. Research on Utilization of Waste Chicken Slaughterhouse (Chicken Feather Meal treated) as Feed Ingredients Protein Source in Broiler Chickens. This studies to explore the best type of treatment for chicken feathers seen on the digestibility of dry matter, organic matter, protein, nitrogen retention, and the value of energy metabolic. Types of processing, namely: 1. processed chicken feather meal cooked by steam pressure 2.5 kgf/cm², temperature of 1400C for 50 minutes; 2. processed chicken feather meal which soaked 0.5% NaOH, followed by 2.5 kgf/cm² cooking vapor pressure, temperature 1400C for 50 minutes; 3. processed chicken feather meal fermented by Bacillus licheniformis. S followed by a vapor pressure of 2.5 kgf/cm² cooking, the temperature of 1400C for 50 minutes. The results showed that treatment with chicken feathers by soaking in 0.5% NaOH solution for 24 hours, followed by 2.5 kgf/cm² pressure cooking, with a temperature of 1400C for 50 minutes produces chicken feather meal processed mostbest of digestibility, N retention and metabolizable energy value.
