| genetics driven interventions for ex situ conservation of red junglefowl (gallus gallus murghi) populations in india. | genetics driven interventions (gdi) are imperative for ex situ conservation to exhort long-term sustenance of small and isolated populations in captivity as they are more prone to an increased extinction risk due to inbreeding and genetic drift. we investigated constitutive genetic attributes of four captive red junglefowl (rjf) populations in india, to facilitate the prioritization of the birds to formulate an effective breeding action plan. all the four rjf populations were found to be evident ... | 2013 | 23813667 |
| cryopreservation of indian red jungle fowl (gallus gallus murghi) semen. | the population of red jungle fowl is declining and needs special attention for its conservation with suitable approaches. for ex situ in vitro conservation of indian red jungle fowl, establishment of semen cryobank is an appropriate option, for which an extender with adequate retrieval capacity for functional spermatozoa is required. therefore, studies were designed to evaluate a wide range of extenders for cryopreservation of indian red jungle fowl (gallus gallus murghi) sperm to achieve maxima ... | 2016 | 27634420 |
| Intronic Deletions That Disrupt mRNA Splicing of the tva Receptor Gene Result in Decreased Susceptibility to Infection by Avian Sarcoma and Leukosis Virus Subgroup A. | The group of closely related avian sarcoma and leukosis viruses (ASLV) evolved from a common ancestor into multiple subgroups, A to J, with differential host range among galliforme species and chicken lines. These subgroups differ in variable parts of their envelope glycoproteins, the major determinants of virus interaction with specific receptor molecules. Three genetic loci, tva, tvb, and tvc code for single membrane-spanning receptors from diverse protein families that confer susceptibility t ... | 2011 | 22171251 |
| dimethyleacetamide improves the cryosurvivability of indian red jungle fowl (gallus gallus murghi) sperm. | it was hypothesized that dimethyleacetamide (dma) can be used as an alternate to glycerol for cryopreservation of indian red jungle fowl semen. four concentrations of dma (4%, 6%, 8% and 10%) in extender were compared with previously optimized cryopreservation protocol based on 20% glycerol (control) for indian red jungle fowl. sperm motility, plasma membrane integrity, viability, and acrosome integrity were assessed at the stage of post-dilution, cooling, equilibration, and freeze-thawing. the ... | 2017 | 28779613 |
| cryopreservation of indian red jungle fowl (gallus gallus murghi) semen with polyvinylpyrrolidone. | the indian red jungle fowl is a sub-species of the genus gallus native to south asia; facing high risk of extinction in its native habitat. during cryopreservation, permeable cryoprotectants like glycerol are usually employed and we previously showed encouraging results with 20% glycerol. because bird spermatozoa contain very little intracellular water, the possibility of replacing an internal cryoprotectant by an external one is opened. in the present study, we tested the replacement of interna ... | 2017 | 28757053 |
| effect of season and age on indian red jungle fowl (gallus gallus murghi) semen characteristics: a 4-year retrospective study. | the reproductive potential of the adult males is expected to vary with age/season and largely differ not only in closely related avian species but even in subspecies, breeds and/or strains of the same species. thus, it is pre-requisite to have knowledge of seminal parameters to achieve maximum production potential of at-risk species for ex situ in vitro conservation programs. a 4-year study was designed to evaluate the effect of age and season (spring, summer, autumn and winter) on semen charact ... | 2017 | 28708490 |
| genetic evidence from indian red jungle fowl corroborates multiple domestication of modern day chicken. | domestication of chicken is believed to have occurred in southeast asia, especially in indus valley. however, non-inclusion of indian red jungle fowl (rjf), gallus gallus murghi in previous studies has left a big gap in understanding the relationship of this major group of birds. in the present study, we addressed this issue by analyzing 76 indian birds that included 56 g. g. murghi (rjf), 16 g. g. domesticus (domestic chicken) and 4 g. sonneratii (grey jf) using both microsatellite markers and ... | 2008 | 18544161 |
