Four trials were conducted with young pigs to evaluate the effect of dietary level of vomitoxin-contaminated corn on performance and pathology. A dietary level of approximately 20 ppm vomitoxin caused vomiting, 12 ppm vomitoxin caused almost complete feed refusal and 1.3 ppm caused a significant depression in feed intake and rate Of gain. No lesions(More)
A balance experiment was conducted with hens fed a high level of vomitoxin (V) to study the effect on live performance, egg quality, and tissue residues of V. Twenty Single Comb White Leghorn (SCWL) hens, approximately 26 weeks of age, were individually housed in metabolic cages and fed a control (C) or V (82.8 mg/kg) diet for 27 days. No significant(More)
BACKGROUND Specific proteins have traditionally been analyzed using methodologies such as immunonephelometry on specialized analyzers. It is now possible to perform specific protein testing on clinical chemistry analyzers using immunoturbidimetry. Performance characteristics of turbidimetric assays for eight common specific proteins were evaluated against a(More)
Thirty barrows (average weight 8.4 kg) were used in a 3-wk experiment to determine the effects of the ingestion of vomitoxin (deoxynivalenol)-contaminated feed on performance and blood chemistry. The barrows were assigned randomly to consume either: 1) a control diet (C), fed ad libitum, 2) a vomitoxin contaminated diet (V; 10.5 ppm), fed ad libitum, or 3)(More)
Single Comb White Leghorn hens at 58 weeks of age were given control (C) and vomitoxin (V)-contaminated feed for 4 weeks; then the V treatment was changed to C for 2 subsequent weeks. Fusarium graminearum-infected corn was substituted for sound corn to attain a practical extreme of 38 ppm V. Hen-day production, feed consumption, body weight, and gross(More)
Ninety pigs approximately 5 weeks of age were used in an investigation of the influence of three levels of supplemental selenium (0, .60 and 1.20 ppm), and three levels of supplemental vitamin E (0, 60, 120 ppm) in a factorial arrangement, on reproduction. The pigs were confined to 18 pens with three gilts and two boars per pen. "/'he basal diet was(More)
A method is described for the isolation of secondary lysosomes from homogenates of rabbit liver; The uptake of Triton WR-1339 by rabbit-liver lysosomes when administered by intraperitoneal injection was used to decrease the density of secondary lysosomes. Lysosomal fractions prepared by this method contain an NAD nucleosidase (NAD glycohydrolase, EC(More)
