Product Name: Feather Powder Protein Animal Feed Model NO.: 55%60%50% Type: Amino Acid Function: Amino Acid Additives Shape: Powder Certification: ISO Trademark: Tianyuan Transport Package: 25 Kg/Bag Specification: 25 kg/bag Origin: Hebei China Product Description Product DescriptionRich in proteinThe most important poultry by-product at a rendering plant is feather meal. 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. Raw feathers are relatively insoluble and have a very low digestibility of 5% due to the high keratin content and the strong disulphide bonding of the amino acids, but with the controlled technology available today, we are able to convert a relatively insoluble protein into a palatable and highly digestible protein source for mulching ruminants. To make FM digestible it must first be converted through a hydrolysis process. Hydrolysation is completed by cooking the feathers with steam. Hydrolysed feather contents 40% to 65% moisture. This moisture must be reduced to 8% for improving shelf life as an animal feed.Why to use feather mealFeather waste from the poultry processing industry can potentially be used as a protein source in animal feeding operations. Improvements in current processing methods that hydrolyse proteins in feathers to make them more digestible for non-ruminant animals have led to the availability of high-quality hydrolysed FM that could provide a viable economic livestock feed. The crude protein content of feather meal does not suffer from the demerits ofanti-nutritional factors like other available counter parts.The crude protein content of feather meal does not suffer from the demerits of anti-nutritional factors like other available counter parts. During the 50's and 60's there was considerable prejudice against feather meal as a result of its low and variable digestibility which at that time was a reflection of the processing conditions. However, a considerable amount of research was carried out by several workers which has demonstrated that feather meal is a useful protein supplement for inclusion in broiler diets too.Feathermeal benefitsEnergy value of FMThe feeding value of feather meal is affected not only by protein, but also by energy content of it. 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. It is reported that the energy content of feedstuffs, especially FM in terms of TMEn, strongly depends on their chemical composition. The metabolisable energy content of well processed feather meal is, to a large extent, dependent on fat content in raw materials.Initial work to determine the energy value of FM was carried out using broilers birds. It was considered that the NRC values were too low. Pesti, upon investigation of the initial data, found that when FM was included in diets at 40% level in the ration, the energy value was low, as the animals were unable to digest and absorb the amount of protein offered. But when it was used at the levels of 20%, the energy value was much higher than NRC published values (2.36 kcal/g) and it was suggested that a value of 3.07 Kcal/g (12.8MJ/kg) was more appropriate.True metabolisable Energy (TMEn) values vary from 3092 to 3996 Kcal/kg and mainly depend upon the fat content of FM which varies from 1.8 to 12%. metabolisable energy can be estimated from the fat content of well processed FM from the equation, TMEn (kcal/kg dry matter) = 2862 + 77(% fat).Amino acid availability in FMThe direct relationship exists between the quality of an animal protein source and its available amino acids. In recent feed formulation, considerable attention has been focused on the available amino acids content of feed ingredients. Although the animal protein sources have high values of available amino acids and the availability of amino acids can vary greatly with the quality. There are many methods for the determination of available amino acids. Indirect assays for determination of availability include physical and chemical analysis method. In case of direct method, considerable attention has been focused on the precision for determination of digestibility of amino acids. There is need to determine the relationship between the quality of feed ingredients and their available amino acids. A significant amount of certain sulphur amino acids like cysteine, methionine and a sulphur derived component such as cystine are important for the proper growth and development. These amino acids play an important role in the growth performance.
