Human Metapneumovirus in Turkey Poults
This study was conducted to reexamine the hypothesis that human metapneumovirus (hMPV) will not infect turkeys. Six groups of 2-week-old turkeys (20 per group) were inoculated oculonasally with 1 of the following: noninfected cell suspension; hMPV genotype A1, A2, B1, or B2; or avian metapneumovirus (aMPV) subtype C. Poults inoculated with hMPV showed nasal discharge days 4-9 postexposure. Spec...
متن کاملEffects of starvation and refeeding on tissue zinc, copper and iron in turkey poults.
The effects of starvation and refeeding of 2-wk-old turkey poults on serum and tissue levels of zinc, copper and iron were investigated. Serum concentrations of zinc and copper declined during 4 d of starvation. Refeeding for 24 h following a period of starvation restored serum copper to levels similar to those in the fed controls but failed to elevate zinc levels. Liver concentrations and tota...
متن کاملThe zinc requirements of broiler chicks and turkey poults fed on purified diets.
Chicks and turkey poults were fed for 3 weeks on low-zinc diets, prepared from purified ingredients, supplemented with zinc oxide at graded levels. Birds of both species given the unsupplemented basal diets grew poorly, with high mortality rates. All had severe hyperkeratosis but bone development was normal. Only when birds received diets with low concentrations of added Zn were leg abnormaliti...
متن کاملInhibition of tumor growth by dietary zinc deficiency.
SUMMARY The effect of different levels of zinc intake on tumor growth was studied by implanting Walker 256 carcino-sarcoma into weanling Sprague-Dawley rats maintained on laboratory chow or on a zinc-deficient synthetic diet. Three experimental groups receiving this synthetic diet were given 0, 50, or 500 parts per million, respectively, of zinc ion in the drinking water. The latter 2 groups we...
متن کاملThe response of broiler chickens and turkey poults to dietary energy supplied either by fat or carbohydrates.
The efficacy of fat and carbohydrates as energy sources was compared in 1- to 4- and 4- to 7-wk-old broiler chickens and in 16- to 19-wk-old turkeys. An increase in dietary energy by carbohydrate was made by a graded replacement of wheat bran by wheat. Energy was increased by fat through a graded replacement of soybean hulls with refined soybean oil. In the experiments with broiler chickens, th...
