“…In the present study, addition of Mn to a corn-soybean meal basal diet did not influence laying performance and fertility of broiler breeders during the experimental period from 32 to 40 wk of age, which was inconsistent with previous results obtained from commercial laying hens (Gallup and Norris, 1939;Leach and Gross, 1983). The inconsistencies might be due to the differences in layer age or degree of Mn deficiency in the basal diet.…”

“…These results imply that the Mn content of the corn-soybean meal basal diet might be sufficient for maintenance of egg production during the experimental period but not enough for the deposition in the eggs, thereby affecting subsequent hatchability and embryo development. As previously reported, when the eggs contain low Mn, the embryos died during the incubation, being unable to initiate or to complete the process of hatching (Gallup and Norris, 1939). Indeed, the Mn content in egg yolk from broiler breeders fed the control diet was significantly lower than that from broiler breeders fed the diet supplemented with 120 mg Mn/kg.…”

“…Manganese deficiency in the hen causes decreased hatchability and increased mortality of embryos (Gallup and Norris, 1939). Manganese is a crucial component of the metalloenzyme manganese superoxide ABSTRACT: To investigate whether supplementing manganese (Mn) to the maternal diet could reduce the deleterious effect of heat stress on the developing embryo, the hatchability, antioxidant status, and expression of heat shock proteins (HSP) were evaluated in chick embryos under normal and high incubation temperatures.…”

To investigate whether supplementing manganese (Mn) to the maternal diet could reduce the deleterious effect of heat stress on the developing embryo, the hatchability, antioxidant status, and expression of heat shock proteins (HSP) were evaluated in chick embryos under normal and high incubation temperatures. A completely randomized design ( = 6) with 2 maternal dietary Mn treatments (unsupplemented control basal diet versus the basal diet + 120 mg Mn/kg as inorganic Mn) × 2 incubation temperatures (normal, 37.8°C, versus high, 39.0°C) was used. High incubation temperature did not affect ( > 0.19) hatchability and embryo mortality and development but did increase ( < 0.05) activities of heart manganese superoxide dismutase (MnSOD) and liver copper zinc superoxide dismutase and liver MnSOD mRNA and protein levels in embryos. High incubation temperature also decreased ( < 0.003) HSP70 protein level in the heart but had no effects ( > 0.07) in the liver of embryos. Maternal diet with Mn supplementation not only increased ( < 0.05) the hatchability and Mn content ( < 0.001) in the yolk and embryonic tissues and the activity of MnSOD in the heart ( < 0.004) as well as relative liver weight ( < 0.05) under normal incubation temperature but also decreased ( ≤ 0.05) embryo mortality and HSP90 mRNA level in the liver and heart of embryos. Furthermore, under high incubation temperature, maternal diet Mn supplementation increased ( < 0.002) MnSOD protein expression in the liver of embryos but had no effect ( > 0.43) under normal incubation temperature. These results indicated that high incubation temperature induced self-protective responses of chick embryos with a modification of antioxidant status and a depression of HSP70 protein level. Maternal dietary supplementation of Mn could improve the hatchability as well as antioxidant ability to protect against heat challenge in embryos during incubation.

“…The F f values used in TRS 364 are from Gallup and Norris (1939) (based on experiments with stable manganese), Hill and Mathers (1968) and Dewar et al (1974). The revised TRS database uses only one (3.2 Â 10 À2 d kg À1 ) of the three F f values given by Gallup and Norris (1939), the other two were for animals that were either deficient in Mn or in excess. The other F f value of 6.2 Â 10 À2 d kg À1 used in the revised TRS database is from Dewar et al (1974).…”

Data on radionuclide transfer to domestic chickens and ducks obtained from research performed in the former Soviet Union were reviewed to provide transfer coefficient values (Ff) to poultry and edible egg contents. The majority of the data are from experiments with (90)Sr and (137)Cs, reflecting the importance of these radionuclides after global fallout and major radiation accidents. Data for (3)H, (54)Mn, (59)Fe, (60)Co, (22)Na (65)Zn, (131)I and U are also given. The values derived have been compared with those in the current IAEA Handbook of parameter values for the prediction of radionuclide transfer in temperate environments (TRS 364) and the recent revision which incorporates the values from this paper. The Russian-language data give improved estimates for many radionuclides and the revised handbook is now based on the better quality data given for chronic administration.
