rice bran (rb) is a major by-product, produced from the rice milling process. this study was conducted to evaluate the performance, egg quality, and blood biochemical parameters of 288 hy-line laying hens fed diets with rice bran and commercial microbial phytase natuphos®5000. the experiment was a 4×2 factorial one with four rb levels (0, 5, 10, and 15%) by two phytase levels (0 and 5000 ftu/kg...

the present study was conducted to determine the effects of rice bran and dietary multi-enzyme (natuzyme) on performance, egg quality, and blood biochemical parameters of 288 laying hens during 12 week. this experiment was conducted in a completely randomized design in a factorial arrangement of 4×2, with four different levels of rice bran (0, 5, 10 and 15%) and two levels of multi enzyme (0 an...

Explicit solutions of the two-dimensional floating body problem (bodies that can float in all positions) for relative density ρ 6= 1 2 and of the tire track problem (tire tracks of a bicycle, which do not allow to determine, which way the bicycle went) are given, which differ from circles. Starting point is the differential equation given by the author in [8, 9].

this experiment was carried out to study the effects of different levels of canola meal of different fat sources on the egg quality, performance as well egg yolk cholesterol during the first 12 weeks of age in laying hens (hy-line w-36). throughout the experiment a total of 432 hens were employed in a completely randomized design in a factorial arrangement of 3×4, with three levels of canola me...

The aim of this study was to evaluate different feeding schedules and their relationship to calcium (Ca) and phosphorus (P) plasma levels and egg quality of broiler breeders. The feeding schedules were: single feeding at 8:00 AM; twice daily feeding (50% at 8:00 AM and 50% at 3:00 PM) and single feeding at 3:00 PM. 330 female and 45 male Cobb 500 broiler breeders were used from 40 to 60 weeks o...

Synopsis A computer-based technique has been developed for the determination of specific gravity distribution profiles. It has been designed to overcome many of the practical and technical problems that are often encountered in conventional methods of determining specific gravity profiles, such as heavy-liquid analysis. The new technique relies on a minimum of easily obtainable input data (assa...

In recent years, increasing attention has been paid to household impoverishment in Italy. Most of works dealing with this issue are based on summary statistics, which do not capture the whole information contained in the income distribution. The paper applies a non-parametric tool, the “relative distribution”, to Italian household income data during 2002-2004. The relative density function is a...

BACKGROUND This study compares the efficiency of identifying the plants in an area of semi-arid Northeast Brazil by methods that a) access the local knowledge used in ethnobotanical studies using semi-structured interviews conducted within the entire community, an inventory interview conducted with two participants using the previously collected vegetation inventory, and a participatory worksho...

A preliminary study of the mechanical properties of auxetic cellular material consisting of re-entrant hexagonal honeycombs is presented. For different scales of the honeycombs, the finite element method (FEM) and experimental models are used to perform a parametric analysis on the effects of the Poisson's ratio (cell angle) and the relative density (cell thickness) of honeycombs on bearing cap...
