Ž . Ingestion of condensed tannins decreases feed intake in ruminants. Polyethylene glycol PEG forms high-affinity complexes with tannins. In two experiments carried out on Holstein heifers, Ž . quebracho Q from the Aspidosperma quebracho served as source of condensed tannins. The Ž . aims of the study were i to quantify the effect of Q on feed intake and(More)
A single daily oral dose of polyethylene glycol (PEG) Ð a tannin-binding agent Ð has been shown to substantially improve feed intake and ef®ciency of utilization by sheep and goats consuming tannin-rich forage. The aim of this study was to quantify the effect of supplementing 10 g/day of PEG on the performance of does grazing on Mediterranean woodland and(More)
An ultra-short-time heating system was used to process blood plasma spiked with various viruses (HIV, vesicular stomatitis virus, encephalomyocarditis virus). Virus reduction and recovery of plasma proteins were measured at various temperatures from 65 to 85 degrees C. Processing at 77 degrees C and 0.006 s resulted in a high level of virus kill, including(More)
A database of nearly 2000 yield observations from winter wheat crops grown in UK trials between 1976 and 1993 was used to develop a new model of effects of weather on wheat yield. The intention was to build a model which was parsimonious (i.e., has the minimum number of parameters and maximum predictive power), but in which every parameter reflected a known(More)
n engl j med 366;5 nejm.org february 2, 2012 e9 A 55-year-old man with a 31-year history of type 1 diabetes mel­ litus presented for a routine clinical evaluation, his first in two decades. His insulin regimen consisted of a combination of neutral protamine Hagedorn (NPH) and rapid­acting insulin. In the many years since his diabetes diagnosis, he had(More)
A method to elucidate the nutritional value of goats’ diets in ligneous environments is needed. Near infrared spectroscopy (NIRS) can be applied to fecal material to establish statistical relationships between the reflectance of fecal samples in the near infrared region and the diets consumed. We tested fecal NIRS for the prediction of dietary crude protein(More)
Foraging behaviours of the Damascus, Mamber and Boer goat breeds were compared on the South Carmel mountain ridge in Israel. Dietary choice was determined for a group of 10 or 11 yearling animals of each breed, housed and grazed separately to prevent social facilitation, during a total of 4 (Mamber) or 5 (Damascus and Boer) 4-day periods in the fall of 2004(More)
We conducted this study to describe the intermediate-term periodicities in percentage juniper {Juniperus spp.) in goat diets and to develop optimal sampling schemes to estimate individual animal variation in juniper consumption. Fecal samples were collected from 12 multiparous female Angora goats on Monday and Thursday for a 24-mo period. Percentage juniper(More)
