Microclimate parameters (ammonia, ambient temperature, heat index, and relative humidity) surrounding birds affect the production health status of poultry. Therefore, this study aimed to evaluate impact adding natural zeolite litter Japanese quail on improving microclimate its reflection in growth performance, blood gases, biochemical parameters. A total 1152 chicks were obtained from same hatch at 20th selection generation. Chicks allocated into two groups based composition: Group 1: wheat...

Six new (1, 2, 6, 8, 13, and 20) twenty previously isolated (3-5, 7, 9-12, 14-19, 21-26) steroids featuring thirteen different carbocycle motifs were from the organic extract of soft coral Sinularia polydactyla collected Hurghada reef in Red Sea. The structures relative configurations natural products have been determined based on extensive analysis their NMR MS data. cytotoxic, anti-inflammatory, anti-angiogenic, neuroprotective activity compounds 3-7, 14-20, 22-26, as well effect androgen...

Baker's yeast, Saccharomyces cerevisiae, is a key component in bread baking. Total of 12 commercial baker's yeast and 2 hybrid strains were compared using traditional quality parameters. 5 with high leavening power the selected evaluated for their alpha-amylase, maltase, glucoamylase enzymes, random amplified polymorphic DNA (RAPD). The results revealed that all have low level alpha-amylase maltase enzymes. Meanwhile, Egyptian strain (EY) had highest content enzymes followed by YH strain. EY...

The main objectives of this study were to detect the most appropriate random regression model (RRM) fit data monthly egg production in 2 lines (selected and control) Japanese quail test consistency different criteria choice. Data from 1,200 female quails for first 5 months 4 consecutive generations an line selected month (EP1) was analyzed. Eight RRMs with orders Legendre polynomials compared determine proper analysis. All choice suggested that adequate included second-order fixed effects,...

The main objectives of this study were to estimate genetic parameters for the survival, longevity and evaluate risk factors occurrence mortality in a Japanese quail line selected high growth rate during period from hatch 21 days age (GR1-21) eight generations its control.

Abstract A total of 1180 1-day-old Japanese quail ( Coturnix japonica ) chicks were used to investigate the effect feathering rates on growth and slaughter traits. Feathering classified based results stepwise regression using numbers lengths both primaries secondaries tail length at 7 10 days age as predictors. At old, number primary feathers had phenotypically positive low correlations (rps) with body weight (BW), whereas medium rps BW different ages. Lengths primary, secondary highly...

This study aimed to investigate the effects of selection for high early growth rate during 1-21 days age (GR1-21) on traits, some plasma constituent and carcass characteristics.An experiment was carried out at farm Poultry Research Center, Faculty Agriculture, Fayoum University continued six generations including 10,024 two lines (the selected line, HGR1-21 control CL) Japanese quail chicks.The had better BW21, BW35, GR1-21, GR1-35 BWG1-35 than CL.Generation significantly affected all...

A total number of 598 Japanese quail chicks from the same hatch at eighth generations selection for high body weight 28 days age (BW ) were used to draw growth curves two lines using Gompertz, Richards and Logistic functions.Line significantly affected all studied weights (BWs) except BW favoring selected line.Males had higher 7 14 than females which 42 .The line highest asymptotic parameter (β 0 relative rate 2 values control both sexes.The program has clearly on increasing pattern in...

Since prehistoric times, medicinal plants and their extracts had been used as prolific sources of medications.Pomegranate is a symbol life, longevity in Aurvedic medicine; pomegranate considered pharmacy up to itself.Despite several previous studies centered the phytochemistry pharmacological actions all Punica granatum L. components, however, date, few reports about variety nana, which implies that this species yet under-investigated.Punica var.nana dwarf popularly planted an ornamental...

Abstract Offspring sex ratios in avian species are of significant scientific interest, with implications for evolutionary biology and poultry production. This study investigated Japanese quail ( Coturnix japonica ), a valuable model other due to its rapid generation interval. The examined the impact selection over generations, age at first egg (AFE), body weight AFE (BW ) on offspring ratios. dataset included 4,282 records from 968 dams eight comprising two lines: one selected high growth...

This research aims to examine the relation between access finance by Micro/Small businesses in term of volume and number on creating new employment opportunities hence positively impacting country financial performance.Based empirical literature, model expressed relationship Micro SME Financing Financial Performance, is obviously discussed delicately examined. Consequently, conceptual, linkage, assumed four hypotheses tested Financed amount micro small enterprises reduction unemployment;...

Abstract The world is suffering from a protein shortage due to population growth and increased food demand, increasing the pressure on poultry breeders boost production. Additionally, Japanese quail (JQ), with their small size, rapid growth, short generational interval, high egg production, offer promising solution address this challenge. A ten-generation study conducted at Fayoum University Poultry Research Center involved 17,806 JQ chicks, which were divided into two lines: one was...

Eighty male New Zealand White (NZW) rabbits aged 5 weeks, with average body weight 823.17±11.13g were randomly distributed into two experimental groups (40 each) till 10 weeks of age.The 1 st group (T ) received diet contains 17% CP (low) vs. 19% (high) for 2 nd ), respectively.Initial and final (IBW FBW), feed intake (FI), daily gain (DBWG), conversion ratio (FCR), an economic evaluation determined.Results showed that the in T significantly improved FBW, DBWG performance index (PI)...

Egg production data used in this work were obtained from records of Fayoumi chickens flock belongs to El-Takamoly poultry project at Al-Azab, Fayoum Governorate. over a 52-wk egg laying period related 1900 hens. All was summarized on weekly basis as eggs per hen week hen-day (survivor) basis. Regarding Wood and McNally models, (a) stands for initial production, parameter value very low (0.001) both models. The increasing rate the peak (parameter b) 2.90 model 2.19 model. Similarly, c,...

easonal abundance of the Egyptian mealybug, Icerya aegyptiaca (Douglas) and relation between population activity, weather factors were studied during 2014 season on ornamental trees Ficus virens Ait at Cairo Giza Governorates.At El-Mireland Garden, Governorate data indicated that total stages mealybug have two activity generations; first one with highest number occurred beginning May while 2 nd generation in early October.On other hand, nymphs also infestation periods, 1 st period was...

Throughout a selection experiment, which extended over five generations: the base and four generations of for augmenting early growth rate (GR) during period from hatch to 21 days age in Japanese quail, total number 8724 birds were used: 1726 population, 5176 selected line (HGR 1-21 ) 1822 control line.The most important results obtained as follows: Genetically, heritability (h 2 all body weights (BW) showed moderate h ranged 0.19 0.29.The GR positively correlated with weekly measured except...
