two experiments were conducted to determine the effect of phytase supplementation on layer hens and broiler chickens performance and compare the use of phytase nutrient equivalency values in feed formulation with those fed conventional diet. in the first ex-periment, 640 commercial broiler chicks were used from 11 to 49 days of age. the ex-perimental units were allocated at random to 4 dietary ...

this experiment was conducted to evaluate the effect of the addition of a multi enzyme (natuzyme-p) to corn-soybean based diets and to determine the enzyme's nutrient equivalency on broiler chicks’ performance. ninety six day-old male broiler chicks were randomly assigned to a number of 24 battery cages in a completely randomized design. the chicks were grown up to 6 wk of age. six diets (...

an experiment was conducted using 640 day-old sexed commercial broiler chicks (ross 308 strain) from 10 to 49 days of age. the experimental design was a completely randomized factorial one. the experimental units (pens) contained 20 chicks each and were allotted at random to 4 dietary treatments × two sexes with 4 replicates per treatment. four dietary treatments were formulated based on corn a...

the objective followed in this study was to determine the amen equivalency of multienzyme natuzyme-p. one hundred and sixty male ross 308 broiler chicks were made use of in the experimentations. graded levels of amen, 2600, 2750, 2900, plus 3050 kcal/kg in the starter, and 2700, 2850, 3000, plus 3150 kcal/kg of the diet in the grower periods were used throughout the study. all the nutrients oth...

β-Carotene is an important dietary source of vitamin A for humans. However, the bioavailability and vitamin A equivalency of β-carotene are highly variable and can be affected by food- and diet-related factors, including the food matrix, food-processing techniques, size of the dose of β-carotene, and the amounts of dietary fat, fiber, vitamin A, and other carotenoids in the diet as well as by c...

Equivalency clauses (Xors or modulo 2 arithmetics) represent a common structure in the SAT-encoding of many hard real-world problems and constitute a major obstacle to DavisPutnam (DP) procedure. We propose a special look-ahead technique called equivalency reasoning to overcome the obstacle and report on the performance of an equivalency reasoning enhanced DP procedure on SAT instances containi...

Between-country comparisons of estimated dietary intake are particularly prone to error when different food composition tables are used. The objective of this study was to describe our procedures and rationale for the selection and adaptation of available food composition to a single database to enable cross-country nutritional intake comparisons. Latin American Study of Nutrition and Health (E...
