Effect of short-term pre-hatch heat shock of incubating eggs on subsequent broiler performance

________________________________________________________________________________ Abstract The aim of this study was to investigate the effect of thermal conditioning of broiler chickens during embryonic development on subsequent performance under standard rearing conditions. During incubation eggs from 32-, 45and 56-week old Ross 308 broiler parent stock were subjected to a 2 h heat shock of 39...

Ability of Hydrogen Peroxide and Timsen to Eliminate Artificially Inoculated Salmonella from Fertile Broiler Eggs

Varying levels (10 to 10/egg) of Salmonella Typhimurium were inoculated onto fertile hatching eggs by immersion. After this, the inoculated eggs were untreated (control), water treated, hydrogen peroxide (1.5%) treated, or Timsen treated (n-alkyl dimethyl benzyl ammonium chloride as a commercial bactericide-fungicide). Hydrogen peroxide was superior to Timsen as an egg treatment to eliminate ar...

Gluconeogenesis differs in developing chick embryos derived from small compared with typical size broiler breeder eggs.

We hypothesized that, as the supply of preformed glucose diminishes during development, the embryo would transition to a greater rate of gluconeogenesis (GNG) and that GNG would be greater in embryos from small vs. typical size eggs. Gluconeogenesis by embryos from small (51.1 +/- 3.46 g) and typical size (65 +/- 4.35 g) broiler breeder eggs was measured by dosing [(13)C(6)]glucose (15 mgxegg(-...
