*'IT IS PROBABLE that coccidia cause greater economic loss among domesticated animals of the temperate zone than any other group of protozoa." Thus Becker ^ aptly indicated the importance of coccidiosis, the specific disease caused by these protozoan parasites. It may be added that the coccidia probably cause greater economic loss among chickens alone than among all other domesticated animals c...

The application of artificial loads to mammals and birds has been used to provide insight into the mechanics and energetic cost of terrestrial locomotion. However, only two species of bird have previously been used in loading experiments, the cursorial guinea fowl (Numida meleagris) and the locomotor-generalist barnacle goose (Branta leucopsis). Here, using respirometry and treadmill locomotion...

BACKGROUND There is a strong need for a recombinant subunit vaccine against fowl cholera. We used a reverse vaccinology approach to identify putative secreted or cell surface associated P. multocida proteins that may represent potential vaccine candidate antigens. PRINCIPAL FINDINGS A high-throughput cloning and expression protocol was used to express and purify 71 recombinant proteins for va...

Blood samples were collected from eight native Japanese breeds of chickens (Miyadi-dori, Ohiki, Onaga-dori, Shoukoku, Tosa-Jidori, Tosa-Kukin, Toutenkou and Uzurao) and two foreign breeds of chickens (White Leghorn and Rhode Island Red) to examine the genetic variability and relationships among the breeds by using a microsatellite DNA technique. Except for the Shoukoku breed, the other Japanese...

Photoperiod is considered to be one of the most effective environmental factor in controlling reproductive cycle and gonadal maturation some mammalian species, but very limited information are available on its effects biology guinea fowl. Therein, we investigated varying photoperiodic treatments morpho-biometry excurrent duct system helmeted fowl (Numida meleagris). A total twenty-one (21) appa...

Runners need dynamic stability to maintain their gait despite uneven terrain and other disturbances. Research on guinea fowl is providing welcome new insight into how this difficult problem is solved.

SKADHAUGE, ERIK, AND BODIL SCHMIDT-NIELSEN. Renal function in domestic fowl. Am. J. Physiol. 2 12 (4) : 793-798. 1967.Roosters were exposed to water and salt loading and to dehydration. The ureteral urine was collected through polyethylene funnels. The glomerular filtration rate (GFR) was found to increase an average of 23 yO from dehydration to hydration, when at the same time the urine flow i...

the objective of the present study was to estimate heritability values for some performance and egg quality traits of native fowl in isfahan breeding center using reml and bayesian approaches. the records were about 51521 and 975 for performance and egg quality traits, respectively. at the first step, variance components were estimated for body weight at hatch (bw0), body weight at 8 weeks of a...
