Lambs (29 +/- 2.5 kg) were fed three diets at various intakes to determine whether diet composition or level of intake was reflected in changes in diet digestibility or ruminal fluid characteristics. In Exp. 1, a 90% concentrated, pelleted diet or a whole shelled corn diet with a pelleted protein supplement was fed at three levels of intake: ad libitum and 92.5 and 85% of ad libitum (n = 15). E...

Previous studies showed that grafting wedges of fresh or cultured anterior quail wing mesoderm into posterior slits in chick wing buds resulted in the formation of supernumerary cartilage in a high percentage of cases. When anterior quail mesoderm, which had been dissociated into single cells and pelleted by centrifugation, was grafted into posterior slits of host chick wing buds, supernumerary...

In this study, 183 livestock feeds and 85 animal manure samples were collected from commercial farms in England and Wales and analysed to determine their heavy metal (zinc, copper, nickel, lead, cadmium, arsenic, chromium and mercury) contents. Zinc and copper concentrations ranged from 150±2920 mg Zn/kg dm (dry matter) and 18±217 mg Cu/kg dm in pig feeds, depending on the age of the pigs. In p...

BACKGROUND/AIMS Percutaneous endoscopic gastrostomy feeding provides enteral nutrition to patients with neurological dysphagia. Thirty-day mortality rates of 4-26% have been reported, with pneumonia being the common cause post-percutaneous endoscopic gastrostomy insertion. MATERIALS AND METHODS This retrospective analysis of percutaneous endoscopic gastrostomy tube insertions in Malta (Januar...

The emergence of Google Earth (GE) as an integrative platform for the visualization of geolocated information is presenting the geospatial community with unique application opportunities and corresponding scientific challenges. In this paper we discuss the extension of GE to function as a four-dimensional (x,y,z,t) virtual spatiotemporal environment through the overlay in it of georectified vid...
