Two novel feather-degrading fungi belonging to Chrysosporium and Microsporum genus were isolated from poultry waste in Goa, India. The fungi produced extra cellular keratinolytic enzyme in a feather meal broth using chicken feather as a sole of carbon and nitrogen source. Maximum enzyme activity was obtained within 96 h (150 U/ml and 90 U/ml for Chrysosporium and Microsporum respectively) of cu...

Nentwich I . , Szépfalusi Zs. , Kunz C. , Spuergin P. , Urbanek R.: Antigenicity for Humans of Cow Milk Caseins, Casein Hydrolysate and Casein Hydrolysate Fractions. Acta Vet. Brno 2004, 73: 291-298. Cow milk casein consists of several fractions each of which have different structure and differing antigenicity. The aim of the study was to investigate the capacity of cow milk casein, casein frac...


 Many differentially expressed genes associated with feather colour in quail embryos can be screened using RNA-seq technology. The aim of this study was to verify the accuracy RT-qPCR. transcriptome embryonic skin tissues quails were sequenced by Illumina HiSeq TM2000 sequencing platform. As a result, 2512 found. Among them, 950 up-regulated white-feather embryos, and 1562 down-regulated....

The aim of this study was to evaluate the biostimulant action (hormone like activity, nitrogen uptake, and growth stimulation) of a plant-derived protein hydrolysate by means of two laboratory bioassays: a corn (Zea mays L.) coleoptile elongation rate test (Experiment 1), a rooting test on tomato cuttings (Experiment 2); and two greenhouse experiments: a dwarf pea (Pisum sativum L.) growth test...

Glucose usually is included in amino acid solutions for intravenous infusion. This has seemed desirable because the amino acids can spare body protein only when sufficient calories are provided. Although the calories so gained (usually 200 for a liter of hydrolysate) are far from enough for this purpose, they do add to the total and besides they might serve particularly efficiently being presen...

Rubber processing industry effluent represents a serious environmental pollution problem especially for underground and surface water. Wastewater collected from rubber processing industry was characterized for their pollution characteristics. Analysis showed that the biological oxygen demand (BOD), chemical oxygen demand (COD), total dissolved solids (TDS), total suspended solids (TSS), total s...

A major problem in total parenteral nutrition is sepsis, particularly that caused by Candida. Studies of four solutions, a casein hydrolysate, a fibrin hydrolysate, and two crystalline amino acid solutions, show that the protein hydrolysate solutions appear to be highly selective for Candida over bacteria, whereas the crystalline amino acid solutions are not. These findings suggest that the cry...

We investigated how exogenous and endogenous glucocorticoids affect feather replacement in European starlings (Sturnus vulgaris) after approximately 56% of flight feathers were removed. We hypothesized that corticosterone would retard feather regrowth and decrease feather quality. After feather regrowth began, birds were treated with exogenous corticosterone or sham implants, or endogenous cort...

The structure and properties of chicken feather barbs makes them unique fibers preferable for several applications. The presence of hollow honeycomb structures, their low density, high flexibility and possible structural interaction with other fibers when made into products such as textiles provides them unique properties unlike any other natural or synthetic fibers. No literature is available ...

Feather pecking in domestic fowl is a behavioral abnormality that consists of mild or injurious pecking at feathers of conspecifics. Previously, it was shown that chicks from a high feather-pecking (HFP) and low feather-pecking (LFP) line of laying hens already differ in their propensity to feather peck at 14 and 28 days of age. As a first step in investigating a possible relationship between t...
