Feathers are rich in protein content called keratin and constitute 7% weight of the live bird, therefore producing a considerable mass which can be converted to valuable meal. Feather Meal: Its Nutritional Value And Use In Dairy And Beef Rations. The nutritional value of feather meal is highly variable, because of the variability of the raw material and the variability added by technological treatments. At low steam pressure, long hydrolysis times are needed to increase FM density and to improve digestibility. Inclusion of the processed, water boiled feather meal up to 3.0% in the diets did not significantly affect mean body weights, feed intake, and feed conversion ratio of broiler chickens. Corn (energy feed) and 48% soybean meal (protein feed) are commonly used as the base feeds in Petersen's equations. On Nov 3 Feathers are rich in protein content called keratin and constitute 7% weight of the live bird, therefore producing a considerable mass which can be converted to valuable meal. Feather meal is also an excellent source of escape protein. On Nov 6 By Our Correspondents A possible means of maintaining supply of broiler meat all year round at cheaper prices is by reducing the cost of production. Indirect assays for determination of availability include physical and chemical analysis method. Newer trends and processing technologies are being taking into account for this purpose. For poultry and animal nutritionists, the relationship between energy and nutrients is important, if the energy content of feather meal is underestimated, then its inclusion in diets will lead to wider calorie-protein ratios, and may contribute to excess fat accumulation in the body. To guarantee the safety of chicken meat for consumers, an organised processing industry is gradually emerging. INRAE CIRAD AFZ © 2017-2020. A major reason for the lack of use of this product is due to very little information existing regarding the nutrient content of the product and its convenience. To make FM digestible it must first be converted through a hydrolysis process. Bielorai R, Iosif B, Neumark H, Alumot E. Ileal absorption of nitrogen was determined for feather meal (FM) samples, using magnesium ferrite as a marker. During the 50’s and 60’s there was considerable prejudice against FM as a result of its low and variable digestibility which at that time was a reflection of the processing conditions. The energy value, amino acid composition and its availability has made it the first preference by animal owners. There is need to determine the relationship between the quality of feed ingredients and their available amino acids. When reducing or eliminating antimicrobial growth promoters (AGP) in poultry production, producers must pay... On Nov 16 Feather meal processed at the lowest pressure had the highest nutritional value, and vice versa. “When the common consensus is that something can’t be done, that is when I get intrigued as a researcher,” says... On Nov 20 In Health, On Nov 27 Author: Arvind Soni, Sagar Chand, S. Talukder, Indian Veterinary Research Institute. In recent feed formulation, considerable attention has been focused on the available amino acids content of feed ingredients. In Home, By Vladislav Vorotnikov However, any other energy or protein feed can be substituted.

Modern broiler processing plants process huge amounts of birds, with a large tonnage of feathers, offal, trims, blood, etcetera. On Oct 5 Processing of this waste as a feedstuff will play a part in solving the world’s protein needs by producing more animal protein and recreating a price structure. Login with your current details or download the Poultry World app, available in all app stores. The crude protein content of feather meal does not suffer from the demerits of anti-nutritional factors like other available counter parts. With an NPK ratio of ~12-0-0, it’s a fantastic supply of nitrogen and not much else. Feather meal is also an excellent source of escape protein. All waste material go through a by-product operation to convert it into value added commodities. True amino acid availability determined with force-fed White Leghorn cockerels demonstrated that increasing pressure decreased true available (TA) cystine (P < 0.05) more than any other amino acid. The effective utilisation of FM can surely increase animal production in terms of milk and meat; therefore it surely will secure its position in animal diets in the near future as a convenient, economically viable, protein rich feed ingredient for all sorts of domesticated animals. In Meat, By Vincent ter Beek In this regard the meat and poultry processing industry is booming; especially poultry production and processing, as the growth rate of it is very high. In research at Purdue University, a combination of feather meal and urea produced average daily gains in growing beef cattle similar to that achieved with soybean meal.
