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...

increase in feed intake of broiler breeder hens, results to incidence of metabolic and hormonal changes and finally leads to poor reproductive performance. an experiment was conducted to evaluate responses of feed-satiated and feed-restricted laying breeder hens to daily injection of an acute dose of progesterone (p4). a total of 64 cobb 500 hens were fed either restricted or ad libitum from 27...

this experiment was conducted to evaluate the effect of increasing levels of alfalfa leaf meal (alm) on egg production, egg traits and blood parameters of laying hens with 144 hy-line (w36) laying hens from 65-75 weeks of age in 4 treatments, 3 replicates and 12 hens in each replicate in a completely randomized design. experimental groups included: 1) control group, 2) group with 1% of alm, 3) ...

BACKGROUND Recent functional studies have demonstrated that the microRNAs (miRNAs) play critical roles in ovarian gonadal development, steroidogenesis, apoptosis, and ovulation in mammals. However, little is known about the involvement of miRNAs in the ovarian function of fowl. The goose (Anas cygnoides) is a commercially important food that is cultivated widely in China but the goose industry ...

A 3 × 2 factorial arrangements with completely randomized design, with a total of 72 Leghorn Hy-line (W-36) laying hens in the second cycle (98 wk old) of production were randomly assigned to 24 wire cages (45.7×30×30 cm3) and fed with diets containing three levels of guar meal (GM; 0, 4 and 8%) and two levels of β-mannanase (Hemicell®) enzyme (0.00 and 0.05%) for 12 wk period. There...

Class noise refers to the incorrect labeling of examples in classification, and is known to negatively affect the performance of classifiers. In this contribution, we propose a boosting-based hybrid algorithm that combines data removal and data reparation to deal with noisy instances. A experimental procedure to compare its performance against no-preprocessing is developed and analyzed, laying ...
