Effects of feathers on instrumental thermoregulatory behavior in chickens
Physiology & Behavior, 1978Abstract Experiments with domestic fowl confirm that normally feathered chickens utilize species-specific behavior and autonomic responses to cold (at least to−5°C) rather than initiate an instrumental response. When the thermally insulative feathers are removed chickens readily utilize the instrumental response and are able to maintain physiological

Valorisation of chicken feathers: Characterisation of chemical properties
Waste Management, 2017The characterisation of the chemical properties of the whole chicken feather and its fractions (barb and rachis), was undertaken to identify opportunities for valorizing this waste product. The authors have described the physical, morphological, mechanical, electrical and thermal properties of the chicken feathers and related them to potential ...

Biosorption of precious metal ions by chicken feather
Applied Biochemistry and Biotechnology, 1996Chicken feather (C-feather) is an intricate network of stable and water-insoluble protein fibers with high surface area and is an abundant bioresource. C-feather protein was found to accumulate various precious metal ions (gold and platinum metals) selectively from their dilute aqueous solutions in high yield and in short contact time, depending on pH ...

Identifying the Ptilopody (Feathered Shank) Loci of the Chicken
Journal of Heredity, 1992A series of crosses was made involving lightly-, and heavily-, and non-feather-shanked chickens in an attempt to clear up the confusion in the literature concerning the inheritance of feathered shanks in chickens. The Langshan and Brahma breeds were both shown to possess the same single shank-feathering locus, but because of their differences in ...

(Chicken feathers keratin)/polyurethane membranes
Applied Physics A, 2010Actually, chicken feathers are considered as waste from the poultry industry; however, 90% of feather structure is constituted by a protein called keratin. In this research, the properties of feather keratin and polyurethane are combined in order to synthesize hybrid synthetic–natural membranes.

Development of Chicken De-Feathering Machine
FUTA JOURNAL OF ENGINEERING AND ENGINEERING TECHNOLOGY, 2019This paper presents the design and fabrication of an electrically-operated chicken de-feathering machine using stainless steel, mild steel, elastomer feather pluckers and electric motor as major materials. The electric motor drives the feather plate (to which the feather pluckers are attached) on which the chicken carcass is placed hence spinning the ...
