These experiments were conducted to determine metabolizable energy and amino acid digestibilities of soybean meal, sunflower meal and canola meal in broiler chickens by using titanium oxide as indigestible marker in intact or caecectomized cockerels. Ileal and total tract digestibility of amino acids were measured using broiler chickens, moreover, digestibility were also determined in the intac...

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...

In the tumor dormant state, small numbers of tumor cells persist in the host without outgrowth to overt neoplasia. The cancer l i t e ra ture contains numerous reports describing recurrence of solid tumors and leukemias years after apparent successful t r ea tmen t of the pr imary neoplasia (1). These reports suggest tha t residual tumor cells can persist in a dormant s ta te during the prolong...
