a total of 2000 records of egg quality of 746 birds and body weight data from 17th generation of fars native fowl breeding station were used to estimate the genetic parameters of egg quality and body weight traits. six univariate animal models with different random effects were fitted for each trait. a model with direct additive genetic and maternal permanent environmental effects was the most ...
abstract tasks nowadays are at the center of attention in sla research. task types is one of the critical issues in this regard, their effectiveness and suitability to any particular context, their characteristics and the result they yield are among some of these issues. on the other hand, discourse markers (dms) have been very much investigated and their effectiveness in conveying the meaning...
The present study was conducted to investigate the variation in the lipid profile between Egyptian breed Fayoumi and commercial strain ISA-Brown. Forty 32-wk-old ISA-Brown and thirty-five 36-wk-old Fayoumi were housed individually in separated layer cages in opensystem housing. Four weeks later, Body weight was recorded and egg weight, number, and composition were measured. In addition, lipid p...
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...
effects of mating sex ratios on production performance in indian peafowl were investigated at punjabwildlife research institute, gatwala faisalabad. research was conducted from may through august 2007 toexplore the most productive mating sex ratio. the sex ratios have a significant effect on egg production.maximum mean eggs (1.63) were produced by the sex ratio 1:2 while maximum egg fertility (...
Turkeys from two BW groups (which averaged 11.8 and 12.9 kg, Normal and Heavy, respectively) were photostimulated at either 29 or 31 wk of age to determine what effects age-associated changes in hen carcass characteristics, egg weight, and egg components have on subsequent poult weight at hatching during the first 10 wk of production. Carcass measurements were determined from a subsample of hen...
An experiment was carried out to study the effect of different levels (3.06, 3.23, 3.4, 3.57 and 3.74%) of calcium and vitamin D3 supplementation (2000, 2200 and 2400 IU/kg diet) on the performance of laying hens. In a completely randomized design and in a 5 × 3 (15 treatments) factorial arrangement, two hundred and forty (240) white leghorn laying hens strain Hy-Line W 36, 26 weeks old, were d...
this research was conducted to examine the effect of a concurrent training on rest level of leptin of plasma and some hormonal factors in non-athlete subjects. the research population included non-athlete men who didn’t participate in any organized sport activities. 30 men were chosen voluntarily among the above-mentioned population and were divided into 2 groups: experimental (15 subjects) an...

The purpose of this study was to establish the effects of ultrasonic treatment of eggs on egg weight loss, hatchability, tibia mineral content, chick performance, and eggshell microbial activity. A total of 600 fresh eggs was randomly divided into 5 groups. Treatments were no ultrasound, 35 kHz for 5 min, 35 kHz for 10 min, 35 kHz for 15 min, and eggs sprayed with benzalkonium chloride solution...
