Dietary Ca has been reported to influence the amount of phytate excreted from broilers and affect the solubility of P in excreta. To address the effects of dietary Ca and phytate on P excretion, 12 dietary treatments were fed to broilers from 16 to 21 d of age. Treatments consisted of 3 levels of phytate P (0.10, 0.24, and 0.28%) and 4 levels of Ca (0.47, 0.70, 0.93, and 1.16%) in a randomized ...

Two experiments were conducted to estimate standardized P retention (SPR) values of dicalcium phosphate (DCP), monocalcium phosphate (MCP), and monopotassium phosphate (MKP) in broilers. In total, ninety-six 22-d-old male broilers with similar BW (780 g average) were used in each experiment. The chicks were randomly allotted to 1 of 4 treatments (P-free, DCP, MCP, or MKP diets) with 6 replicate...

It has recently been stated (Sheldon, 1949) that none of the methods described for conducting ' balance ' experiments on incontinent children have as yet proved satisfactory. We are prompted, therefore, to describe the method which we have employed for some time in this hospitaL A special type of bed is used, designed on the principle of the metabolic cage for animal experiments. It consists of...

this experiment was conducted to determine the ame, amen, tme and tmen of beet pulp fed to male ostriches at  their 90 d of age. different levels of beet pulp (0, 15, 30 and 40%) were fed through replacements in the basal diet. for a determination of ame and amen using marker method, beet pulp was replaced in the basal diet at 40%. a number of 16 vs. 8 ostrich chicks were employed in each of th...

Two experiments were conducted to determine: first, the best time of excreta collection after force feeding of broilers to yield the maximal amount of excreta, and second, nitrogen-corrected true metabolizable energy contents of some poultry feedstuffs including yellow corn, soybean meal, corn gluten meal, canola meal and poultry by-product meal by a new precision-fed chick assay using 3-week-o...
