| effect of cecectomy on water and nutrient absorption of birds. | the effect of the removal of the avian digestive ceca on osmoregulation and on absorption of certain nutrients is reviewed. while data indicate that the ceca have the potential for absorption of a significant quantity of water, several studies have demonstrated that effects of cecectomy on water intake and output are transitory and that compensatory adjustments made within 2 to 3 weeks postsurgery allow cecectomized birds to eat and gain weight normally. however, cecectomized great horned owls e ... | 1989 | 2575133 |
| evolutionary history of the mariner element galluhop in avian genomes. | transposable elements (tes) are highly abundant genomic parasites in eukaryote genomes. although several genomes have been screened for tes, so far very limited information is available regarding avian tes and their evolutionary histories. taking advantage of the rich genomic data available for birds, we characterized the evolutionary history of the galluhop element, originally described in gallus gallus, through the use of several bioinformatic analyses. | 2017 | 28814978 |
| avian transgenerational reproductive toxicity test with in ovo exposure. | ecological risk assessment of environmental pollutants requires effective laboratory assays and extrapolation of the resultant data to wild species. because avian reproductive disorder and accumulation of persistent compounds in wild birds and their eggs have long been observed in polluted regions, we have developed an assay for investigating whether pollutants accumulated in eggs impair the reproduction of the exposed birds and the survival of the next generation using the japanese quail. a typ ... | 2006 | 16758213 |
| inverse relationship between functional maturity and exponential growth rate of avian skeletal muscle: a constraint on evolutionary response. | in this study, we investigate whether a tissue-level constraint can explain the general inverse relationship between growth rate and precocity of development in birds. on the whole, altricial (dependent) chicks grow three to four times faster than the less dependent, more able chicks of precocial species of similar adult mass. we suggest that an antagonism between growth and acquisition of mature function in skeletal muscle constrains postnatal growth and development in most species of birds. al ... | 1994 | 28564466 |
| parthenogenetic embryos from unfertilized chinese painted quail eggs alter albumen ph, gases, and ion concentrations during incubation. | parthenogenesis is a form of embryonic development that occurs without fertilization. recently, parthenogenesis has been reported in chinese painted quail eggs. in japanese quail, it has been shown that albumen ph of incubated fertile eggs is lower than that of incubated infertile eggs. however, it is unknown if alterations, similar to those in incubated fertile eggs, occur in albumen ph, gases, or ion concentrations from unfertilized eggs exhibiting parthenogenetic development. therefore, the o ... | 2016 | 26474681 |
| black soldier fly as dietary protein source for broiler quails: meat proximate composition, fatty acid and amino acid profile, oxidative status and sensory traits. | in the perspective of improving the sustainability of meat production, insects have been rapidly emerging as innovative feed ingredient for some livestock species, including poultry. however, at present, there is still limited knowledge regarding the quality and sensory traits of the derived meat. therefore, the present study tested the effect of a partial substitution of soya bean meal and oil with defatted black soldier fly (hermetia illucens) larvae meal (h) in the diet for growing broiler qu ... | 2017 | 28735587 |
