“…73.4% which is better than commercial feather meal (0.578) or milled feather (0.096) and comparable to whole cell hydrolysate (WCH) (0.834) feather meal produced by fermentation [11]. This suggests that present feather meal can be used as feed for chickens, cattle and fish as reported earlier for feather meal produced by fermentation [21].…”

“…Rangacharyulu et al (2003) observed that fermented silk worm pupae silage (SWP) was nutritionally superior to untreated SWP or fishmeal. Bertsch and Coello (2005) used a strain of keratinolytic bacteria to ferment poultry feather and obtained poultry feather meal with 71% crude protein and improved bioavailability of some amino acids. The objective of this study was to determine the extent to which fish offal could replace fish meal in carp (Labeo rohita) diet while maintaining nutritional quality almost identical to the diet based on fish meal and thus be an ideal cost effective renewable alternative.…”

. 2007. Evaluation of fermented fish offal in formulated diet of the Indian major carp, rohu, Labeo rohita (Hamilton). Acta Ichthyol. Piscat. 37 (2): 99-105.Background. Carp fish offal contains high amount of protein and lipid. The quest for protein sources alternative to fish meal has been a priority in aquaculture research because of growing concerns on the future availability of fish meal for incorporation in fish diets. This study determined the extent to which carp fish offal could be fermented and used to replace fish meal in the formulation of diet for fingerlings of Labeo rohita. Materials and Methods. Fish offal, comprising viscera of carp, was fermented along with mustard oil cake and rice bran anaerobically by a microbial suspension (10 8 cells · mL -1 ) under ambient temperature (27-30ºC). The fermented mixture was mixed with fish meal, mineral-and vitamin mixture to prepare three experimental diets: 1) a reference diet (T1), without any fermentation mixture, containing 40% fish meal, 2) a diet containing 25% fish offal (fermented) and 25% fish meal (T2), and 3) a diet containing 30% fish offal (fermented) and 20% fishmeal (T3). These diets were tested to evaluate growth and biochemical composition of the body of the fingerlings of Labeo rohita and apparent protein digestibility (APD) and intake rate of the diets by the fish. Proximate analysis of feed ingredients, experimental diets, faecal samples and the carcass were performed following the AOAC procedures. Results. Fingerlings of Labeo rohita, reared for 60 days with the diets containing fermented fish offal mixture (T2 and T3), showed higher growth and higher values of protein and lipid in the carcass than those reared with the reference diet (T1). Apparent protein digestibility of the diets did not vary significantly, but average feed intake rate of the T2 and T3 diets were higher than the T1 diet. Conclusions. Fermented fish offal is a viable alternative of fish meal in the formulation of diet for fingerlings of Labeo rohita. Fifty percent replacement of fish meal is possible by a mixture containing 30% fish offal. Further studies are required to improve quality of the fermentation mixture and increase the rate of replacement of fish meal.Keywords: fish offal, recycling, fishmeal, protein, growth, rohu, Labeo rohita ascertained as nutrient sources probably because of inherent difficulties in handling it either in dried or in raw condition. While drying of the offal results in considerable loss of the nutrients, its direct use leads to rapid spoilage of the whole diet. In the present study an attempt was made to evaluate if fish offal (FO) could be fermented and used to replace fish meal (FM) in the preparation of formulated fish diet. The process of fermentation or composting is widely employed in fish diet formulation to decrease the anti-nutritional factors and crude fibre content of plant diet stuff Das 1992, Bairagi et al. 2002). The process of fermentation improves nutritional quality of animal product also. Rangacharyulu et al. (2003) o...

Tavukçuluk işletmelerinin ana atığı olan tavuk tüyleri tekstil lifi olarak incelendiğinde benzersiz elyaf özellikleri göstermektedir. Tavuk tüyü lifleri doğal boşluklu lif yapısına sahiptir. Bu sebeple oldukça düşük bir yoğunluğa sahiptir. Tavuk tüyü liflerinin yoğunluğu 0,8 gr/cm 3 ile 1,5gr/cm 3 arasındadır. Boşluklu lif yapısı ile ısı izolasyonunda iyi bir performans potansiyeline sahiptir. Bu çalışma, tavuk tüyü liflerinin herhangi bir yapısını ayırmaksızın bütün olarak değerlendirmek üzere tasarlanmıştır. Çalışmada farklı elyaf kombinasyonları ile birçok kalınlık ve tavuk tüyü takviyesiyle ipliklerin eğrilebilme özellikleri incelenmiştir. Desen seçeneklerinin arttırılması amacıyla tavuk tüyleri doğal boyalarla renklendirilmiştir. Elde edilen ideal boyalı iplik yapısı ile süprem örme kumaş yapısı oluşturulmuştur. Oluşturulan kumaşın ısı transfer değerleri yün esaslı süprem örgü ile elde edilen kumaşla karşılatılarak giyim konforu açısından değerlendirme yapılmıştır.
