The objective of this experiment was to determine the association of glucocorticoids and markers for immune status in finishing beef steers and heifers with DMI, growth, and efficiency. Steers ( = 127) and heifers ( = 109) were individually fed a finishing ration for 84 d with BW measured every 21 d. Blood samples were collected via jugular venipuncture for metabolite (glucose and lactate) and ...

this experiment was conducted to evaluate the effect of increasing levels of alfalfa leaf meal (alm) on egg production, egg traits and blood parameters of laying hens with 144 hy-line (w36) laying hens from 65-75 weeks of age in 4 treatments, 3 replicates and 12 hens in each replicate in a completely randomized design. experimental groups included: 1) control group, 2) group with 1% of alm, 3) ...

this experiment was conducted to evaluation the effects of different levels of untreated and treated green grape leaf with urea on performance, egg quality traits and blood parameters of laying hens. in this experiment 192 hy-line (w-36) laying hens, 35 to 46 wk of age were divided in to 4 treatments with 4 replicates (12 birds per replicate) in a completely randomized design experiment. the tr...

an experiment was conducted to investigate the effects of using different levels of red pepper powder (rp) and marigold flower powder (mf) on egg production, egg yolk color andsome blood metabolites in laying hens. ninety, 103-weeks old laying hens were divided into 5 treatments groups of 6 birds in each cage with 3 replicates in a completely randomized design. the birds were fed a corn-soybean...

To control intestinal schistosomiasis at a national level in sub-Saharan Africa, there is a need for field-applicable markers to measure morbidity associated with this disease. The purpose of this study was to determine whether fecal calprotectin or fecal occult blood assays could be used as morbidity indicators for intestinal schistosomiasis. The study was carried out in Uganda with a cohort o...

vampirolepis nana is the most common cestode in humans especially children. domestic mice and rats can serve as definitive hosts for v. nana. confusion exists over the species status and host-specificity of this tapeworm. in a previous study done by the same authors it was found that the egyptian human isolates of v. nana could be used to infect mice for experimental work. eggs in human feces a...

three experiments were conducted to evaluate the nutritional value of bitter vetch. experiment 1 was conducted to determine the metabolisable energy content of bitter vetch. sixteen adult leghorn roosters were used. forty grams of bitter vetch were precision-fed individually to 12 roosters. in addition, 4 birds were not fed and served as a control treatment in the measurement of metabolic fecal...

Weight gain costs due to infection were higher in sheep than goats, 28 and 17.5%, respectively, for Trichostrongylus colubriformis and 48.7 and 32.2%, respectively, for Haemonchus contortus. The extent of bodyweight cost attributed to anorexia in sheep infected with H. contortus was higher (13.5 g/day) than in sheep infected with T. colubriformis (2.3 g/day). On the other hand, bodyweight cost ...
