Development and nutrient metabolism of embryos from two modern broiler strains.
A progressive selection for broiler live and processing performance traits has changed broiler growth patterns during the post hatch period. However, limited information is available to understand whether changes have also occurred during the embryonic stages. This study aims to examine influences of broiler strain on nutrient availability, embryonic development, and nutrient metabolism during ...
متن کاملEgg yolk environment differentially influences physiological and morphological development of broiler and layer chicken embryos.
Maternal effects are important in epigenetic determination of offspring phenotypes during all life stages. In the chicken (Gallus gallus domesticus), transgenerational transfer of egg yolk factors may set the stage for morphological and physiological phenotypic differences observed among breeds. To investigate the effect of breed-specific yolk composition on embryonic broiler and layer chicken ...

Nutrient Metabolism
Quercetin is a dietary polyphenolic compound with potentially beneficial effects on health. Claims that quercetin has biological effects are based mainly on in vitro studies with quercetin aglycone. However, quercetin is rapidly metabolized, and we have little knowledge of its availability to tissues. To assess the long-term tissue distribution of quercetin, 2 groups of rats were given a 0.1 or...
متن کاملThe Journal of Nutrition Nutrient Physiology, Metabolism, and Nutrient-Nutrient Interactions Differences in Taurine Synthesis Rate among Dogs Relate to Differences in Their Maintenance Energy Requirement
Diet-induced (taurine deficiency) dilated cardiomyopathy is reported more in large than small dogs possibly because taurine biosynthesis rate (TBR) is lower in large than small dogs. The TBR in 6 mongrels (37.96 2.1 kg) and 6 beagles (12.86 0.4 kg) was determined from the fractional dilution rate of urinary [1,2-H2]-taurine, (d4-tau). All dogs were given a 15.6% protein, 0.60% sulfur amino acid...
