Leg problems and resulting mortality can exceed 1% per week in turkey toms starting at approximately 15 wk of age. Dietary supplementation of organic trace minerals (MIN) and 25-hydroxycholecalciferol (HyD) may improve performance, decrease incidence of leg abnormalities, and increase bone strength. Nicholas 85X700 toms were assigned to 4 treatments(More)
The quality of life in leukaemia is as important as its quantity. In fifty-one patients the quality and quantity of life were improved by less aggressive treatment than is usual. By not trying to induce complete remission at all costs, the mobidity and early mortality were reduced and at least an equivalence in survival was obtained.
Poultry diets are typically supplemented with DL-2-hydroxy-4(methylthio) butanoic acid (HMTBA, or the hydroxy analog of methionine) or DL-methionine (DLM). Although HMTBA and DLM provide methionine activity, they are structurally distinct molecules with different physiological characteristics until they are converted to L-methionine. The relative rates of(More)
on improving performance in broilers. A total of 1152 ROSS 308 male birds were randomly allotted to one of the 4 dietary treatments with 12 pens per treatment and 24 birds per pen. The trial was a 2x2 factorial design with 2 types of soybean oil (fresh vs. oxidized) with or without AOX (0.025%). Oxidized soybean oil was produced by bubbling oxygen in a(More)
Platelet survival and splenic sequestration patterns were studied in 32 patients with thrombocytopenia using donor platelets labelled with chromium-51. A shorter mean platelet lifespan was observed in immune thrombocytopenia (ITP) (mean 12 hours) than in hypersplenism (mean 56 hours) or marrow hypoplasia (mean 102 hours). There was no such correlation(More)
