Silky fowl, a breed of chicken, is hyperpigmented in its various internal tissues. The pigment was extracted from various tissues of two strains of Silky fowl to determine its molecular structure and internal distribution. Analysis by infrared spectroscopy showed two spectrum patterns of the pigment in Silky fowl; one is from ovary and testis, the other is from periosteum and feather. The diffe...

C/O specific pathogen-free White Leghorn chickens were intracerebrally inoculated at one day of age with a brain homogenate of Japanese bantams (Gallus gallus domesticus) affected with fowl glioma. Histologically, six of eight inoculated chickens developed nonsuppurative meningoencephalitis in cerebrum and two of them had the characteristic lesions of fowl glioma. Hyperplastic lymphoid foci con...

Pasteurella multocida subspecies multocida is the most common cause of fowl cholera, although P. multocida subspecies septica and gallicida may also cause fowl cholera-like disease to some extent. However, the virulence properties of the different subspecies for various hosts have not been elucidated. The severity and incidence of P. multocida infections may vary considerably depending on sever...

To achieve robust and stable legged locomotion in uneven terrain, animals must effectively coordinate limb swing and stance phases, which involve distinct yet coupled dynamics. Recent theoretical studies have highlighted the critical influence of swing-leg trajectory on stability, disturbance rejection, leg loading and economy of walking and running. Yet, simulations suggest that not all these ...

HREE live poultry viruses-fowl pox, Rous sarcoma and Newcastle diseasehave been employed experimentally at the Agricultural Research Center, Beltsville, Maryland, iin studies designed to test their action on parthenogenesis in eggs of Beltsville Small White (BSW) turkeys. Each of the viruses was found to have an enhancing influence on cells of parthenogenetic origin (OLSEN 1956, 1961; OLSEN and...

This study was conducted to compare growth performance, carcass characteristics and meat quality of 4 breeds of local chicken. A total of 480 1-d-old chicks were distributed to 16 pens, with 4 treatments of breed, 4 replicates and 30 chicks per pen. Three Korean local breeds of white-mini broiler, Hanhyup-3-ho, and Woorimatdag, and a breed of silky fowl were raised under identical rearing and f...

Background: Foreign body in esophagus in birds is rarely reported in literature. Most common site of foreign body in birds is proventriculus and ventriculus. The purpose of this study is to discuss the diagnosis of a large sharp foreign body in the distal third of the neck by plain radiography and its retrieval through esophagotomy and subsequent survival of the fowl. C...

the virulence of pasteurella multocida (p. multocida) serotype a1 for chickens and mice was determined. groups of chicken and mice were exposed intramuscularly and intraperitoneally to various concentration of p. multocida broth culture, respectively. this strain was highly virulent for chickens so that those exposed to only 7 c.f.u. of the organism died in less than 24 hours. groups of mice ex...
