Quail, like chickens, are susceptible to H5N1 subtype highly pathogenic avian influenza virus (HPAIV). Both birds experience high mortality, but quail usually survive a few more days than chicken. To understand why, we monitored quail and chickens after inoculation with 10(6) fifty-percent egg infectious doses of HPAIV A/whooper swan/Aomori/1/2008 (H5N1). The clinical course initiated as depres...

Background: The common quail, Coturnix coturnix, is a migratory bird hunted extensively across Europe. To satisfy this hunting interest, thousands of farm-reared birds are restocked every year. However, restocked individuals are not common quail but hybrids with domestic Japanese quail, C. japonica. Interbreeding between restocked and native birds in the wild allows the entry of alien alleles t...

Using highly extended lampbrush chromosomes from diplotene oocytes, we have examined the distribution of heterochromatin protein 1 beta (HP1 beta) and histone H3 modifications on chicken (Gallus gallus) and Japanese quail (Coturnix japonica) (2n = 78) microchromosomes. Acrocentric microchromosomes of chicken and submetacentric microchromosomes of quail differ in several morphological features. ...

the present study was conducted to investigate the effect of corn substitution with triticale in grower diets (zero, 50 and 100%) with/without exogenous enzyme supplementation on growth performance, digestive organs relative weight, jejunal morphology and blood lipids of quail chicks. two hundred and forty one-day-old unsexed japanese quail chicks were randomly assigned to a completely randomiz...

H9 influenza viruses have become endemic in land-based domestic poultry in Asia and have sporadically crossed to pigs and humans. To understand the molecular determinants of their adaptation to land-based birds, we tested the replication and transmission of several 1970s duck H9 viruses in chickens and quail. Quail were more susceptible than chickens to these viruses, and generation of recombin...

Two experiments were conducted to evaluate the effect of substituting different levels of hazelnut kernel oil meal (HKOM) for dehulled soyabean meal (DSBM) in diets for Japanese quail. Five diets in which HKOM was replaced with 0, 25, 50, 75 and 100% of DSBM protein in a growing diet for a 5 week period using 450 Japanese quails of initial age of 1 week and in a layer diet for a 112 days period...

We have shown previously that: (1) female Japanese quail, Coturnix japonica, increase and male Japanese quail decrease their tendencies to affiliate with potential sex partners after seeing them mate, and (2) in both sexes of quail, affiliative preferences and choice of a sex partner are highly correlated. Here we predict that because effects of a prior male's sperm on a second male's probabili...

Feed is one of the determining factors for success livestock production because it takes up 70-80% costs. High-protein feed ingredients are high-priced ingredients, so necessary to use non- conventional feeds. The golden snail a pest that interferes with rice growth in agricultural areas. has high protein content very efficient be used as source ingredient. In this study, fermented snails form ...
