Acetylation of Chicken Feathers for Thermoplastic Applications

Journal of Agricultural and Food Chemistry, 2011
Poultry feathers are renewable resources, inexpensive and abundantly available, but have limited applications. Although keratin extracted from feathers has been chemically modified, there are no reports on the chemical modification or development of thermoplastics from poultry feathers.

FEATHER MEAL PREPARATION FROM CHICKEN FEATHERS AND ITS APPLICATION

Asian Journal of Microbiology, Biotechnology & Environmental Sciences, 2022
Feather meal was prepared in powdered form from chicken feather waste, by defatting process. For the overall growth of the wheat crop feather meal used as a bio-fertilizer. In the presence of feather meal, the height of test leaves (39cm), number of wheat plant leaves (T) (213) was found to be increased as compared to standard (36.5cm), (123 ...

Steroid binding to feather follicles in the chicken

Journal of Endocrinology, 1986
ABSTRACT Steroid binding profiles in chicken feather follicles were studied in vitro. Progesterone and promegestone were bound specifically with high affinity (dissociation constant = 7·79 nmol/l in females and 2·0 nmol/l in males) and with low capacity to the high-speed supernatant fraction (cytosol) of homogenized feather follicles.

Degradation of chicken feathers by Chrysosporium georgiae

Mycopathologia, 1998
Using a baiting technique, Chrysosporium georgiae was isolated from chicken feathers. Twenty-eight different fungal isolates were evaluated for their ability to produce keratinase enzymes using a keratin-salt agar medium containing either white chicken feathers or a prepared feather keratin suspension (KS).

Biosorption of phenol by chicken feathers

Environmental Engineering and Policy, 1999
This work aimed at exploring the potential use of chicken feathers as a biosorbent for the removal of phenol from aqueous solutions. Batch kinetics and isotherm studies were performed to evaluate the effects of process parameters such as pH, temperature, initial phenol concentration, and sorbent concentration.

A Feather-Trap System for the Removal of Chicken Feathers from Laboratory Sewage

Avian Diseases, 1992
A simple feather-trap system is described for use on the drain lines of buildings housing poultry for research or other purposes where floors are frequently washed. The trap uses disposable plastic-mesh bags that can efficiently remove almost all feathers from the water, preventing sewer lines from being blocked by compacted feathers.

Feather Lesions in Cyclophosphamide-Treated Chickens

Avian Diseases, 1981
One-day-old White Leghorn chickens each treated with 4 mg of cyclophosphamide for 3 consecutive days developed feather lesions 4 days after treatment. The lesions were characterized by short feathers with an absence of barbs mainly in the proximal portion and sometimes in the mid- or distal portion of the rachis.

A Preliminary Investigation of Piezoelectric Effects in Chicken Feathers

IEEE Transactions on Biomedical Engineering, 1970
Piezoelectric effects have been measured experimentally in chicken feathers. Quill sections subjected to alternating electric stress respond with an axial twisting motion that has a well-defined resonant mode. Conversely, subjecting the quill to mechanical stress produced an electrical signal.

The contribution of feathers in the spread of chicken anemia virus

Virus Research, 2008
Chicken anemia virus (CAV) spreads vertically and horizontally, however, the process is mostly still obscure. To further clarify the horizontal CAV spread, we examined the contribution of feathers. We demonstrated that CAV could be amplified from DNA purified from feather shafts of experimentally infected chicks, and the process efficacy was evaluated ...
