in order to determine the optimal levels of energy and protein in grower diet of japanese quail, 360 dayold japanese quails were used in a 3×3 factorial arrangement of dietary treatments that comprised threelevels of metabolisable energy (2750, 2850, and 2950 kcal/kg) and three levels of crude protein (24, 26and 28 percent) with four replicates per treatment in a completely randomized design. f...
This paper proposes a patch antenna array as an alternative feed for dish antennas on board satellites to solve the weight problem constituted by conventional feed horns. An 8x1 linear, C-Band, circular patch antenna array configuration with a broadside radiation pattern is designed as feed for a dish antenna with F/D ratio of 0.36 corresponding to aperture illumination of 140. The result of an...
The aim of this study was to investigate the differences in production performance, use of nest box, and external appearance of 2 strains of laying hens kept in conventional and enriched cages. Lohmann Brown Classic (LB, n=532) and Lohmann LSL Classic (LW, n=532) hens were housed from 16 to 73 wk in either conventional cages or enriched cages. Enriched cages had a nesting area, scratch pad, per...
The purpose of this research was to evaluate the effect of early life nutrient restriction and subsequent intermittent lighting schedule on performance in broiler. In a factorial experiment, the effect of three levels of feeding regimes and two levels of lighting schedule were investigated using 480 day-old male Hubbard chicks. The broiler chickens were randomly distributed over two rooms consi...
The objective of this study was to investigate the effects of three levels of threonine (100, 95 and 90% of NRC requirements) with or without of multi strains probiotic (Primalac) on performance, carcass characteristics and blood metabolites of Japanese quails. A total of 180 one-day-old male Japanese quails were randomly allocated to six treatments with three replicates and 10 birds per each. ...
In this research, influence of Revabio enzyme on improving anti-nutritional of wheat bran (high in fiber, non-starch polysaccharides and phytate) were investigated. The total number of 320 commercial male broiler chicks (Ross 308) in a factorial experiment 4×2 with four replications were used. Treatment consists of four levels of wheat bran (0, 10, 15 and 20 percent) and two levels of enzyme (0...
the effects of different dietary levels of soybean oil (2, 4 and 6%) and probiotic primalac (0, 0.1 and 0.15 %) were investigated on performance and immune system of broiler chickens from day one to day 42 of age. for this purpose, five hundred and forty day-old male broiler chicks (cobb) in 9 groups of 60 each were used. the birds of each group were divided into 6 pens of 10 birds. the experim...
BACKGROUND Environmental exposure assessments often require a study participant's residential location, but the positional accuracy of geocoding varies by method and the rural status of an address. We evaluated geocoding error in the Agricultural Health Study (AHS), a cohort of pesticide applicators and their spouses in Iowa and North Carolina, U.S.A. METHODS For 5,064 AHS addresses in Iowa, ...
a one dimensional dynamic model for a riser reactor in a fluidized bed catalytic cracking unit (fccu) for gasoil feed has been developed in two distinct conditions, one for industrial fccu and another for fccu using various frequencies of microwave energy spaced at the height of the riser reactor (fccu-mw). in addition, in order to increase the accuracy of component and bulk diffusion, instanta...
