The Effects of Nano and Micro Particle Size of Zinc Oxide on Performance, Fertility, Hatchability, and Egg Quality Characteristics in Laying Japanese Quail.

The current trial was conducted by using the 288 Japanese quails to evaluate the effects of a zinc-deficient diet supplemented with nano and micro zinc oxide on performance, fertility, hatchability, and egg quality characteristics. In this experiment, birds were randomly allocated to 9 dietary treatments includes diets supplemented with nano or micro particles of zinc oxide (amount of ZnO supplement for each treatment) to supply 49, 74, 99, and 124 mg zinc per kilogram of diet in a factorial arrangement (2 × 4) and a control non supplemented diet (24 mg/kg) with four replicates of eight birds (six females and two males) in each pen. Birds were fed the experimental diets from 47 to 75 days of age and had free access to water and feed during the experimental period.

A high-efficient batch-recirculated photoreactor packed with immobilized TiO2-P25 nanoparticles onto glass beads for photocatalytic degradation of phenazopyridine as a pharmaceutical contaminant: artificial neural network modeling.

In this study, removal efficiency of phenazopyridine (PhP) as a model pharmaceutical contaminant was investigated in a batch-recirculated photoreactor packed with immobilized TiO2-P25 nanoparticles on glass beads. Influence of various operational parameters such as irradiation time, initial concentration of PhP, volume of solution, volumetric flow rate, pH and power of light source was investigated. Results indicated that removal percentage increases with the rise of irradiation time, volumetric flow rate and power of light source but decreases with the rise of initial concentration of PhP and volume of solution.

Genetic polymorphism of the CAPN1 gene is associated with meat quality traits in Japanese quail.

1. The objective of the study was to investigate the polymorphisms in two regions of the calpain 1 (CAPN1) gene and their association with breast and thigh meat quality in Japanese quail (ultimate pH (pHu), lightness, redness, yellowness, drip loss, thawing-cooking loss, water holding capacity and shear force, SF). 2.

Effects of different levels of hatchery wastes on the performance, carcass and tibia ash and some blood parameters in broiler chicks.

This experiment was conducted to evaluate the effects of different levels of Hatchery Wastes (HW) on performance, tibia ash, blood calcium and phosphorus concentrations in broiler chickens. Birds were fed a corn-soybean meal diet for 7 days. The experimental treatments included a corn soybean meal diet and 3 other treatments containing 1.
