In vivo nuclear magnetic resonance (NMR) imaging and spectroscopy techniques were used to monitor changes in P- and H-containing molecules in embryos of two broiler strains (30 and 31) differing genetically in fat content and ranging in age from 0 to 20 days of incubation. Chemical analysis showed that Strain 30 has more carcass fat than Strain 31 at market(More)
The purpose of the present experiment was to examine the inner structure of the egg using magnetic resonance imaging (MRI). Proton images of fertile and infertile eggs and eggs from hens fed a corn-based or a flax-based diet were generated using a Spectroscopy Imaging Systems unit. Phantom eggs, made from homogenized albumen and homogenized yolk in a(More)
Labelled particles were prepared by mordanting low concentrations (0.1 or 5 g/kg dry matter) of chromium to neutral-detergent-extracted stems (1-2 mm or 10 mm in length) of bromegrass (Bromus inermis). These were used in the study of reticulo-rumen particle kinetics of four steers given bromegrass hay and from the results a quantitative model of particle(More)
Phosphorus-containing compounds of 18-d-old embryos from two broiler chicken lines, differing in body fat content, were measured using in vivo 31P nuclear magnetic resonance (NMR) spectroscopy. Subsequently, the same birds were slaughtered at 8 wk of age and the whole body was analyzed for body fat content. The birds of the fat line had lower (P = .002)(More)
Feeding behavior, water intake and cardiac rhythm were measured following injections of Ca2+ and(or) Mg2+ into the lateral ventricles of sheep. Injections of 20 mumoles of either Ca2+ or Mg2+ elicited an eating response approximately three to four times greater than normal. The effect of Ca2+, however, appeared to be more powerful than that of equimolar(More)
