چکیده

this investigation aimed to assess genetics of body conformation and feed efficiency traits in a control line of rhode island red (rir) chicken taking single hatched out pedigreed 100 chicks at central avian research institute, izatnagar, india. data was analyzed by least squares analysis of variance. least squares means of chick weight (cw), body weight (bw), shank length (sl), keel length (kl), breast angle (ba), body weight gain (wg), feed intake (fc) and feed conversion ratio (fcr) were estimated at various weeks of age. sex had significant effect on ba at 4th week, sl at 12th week, sl and kl at 16th week; males being better than females throughout the ages, but sex did not show any significant effect on any feed efficiency traits; though males performed better than females almost at all ages. sire had significant effect on cw, kl at 6th week, sl, kl and ba at 12th week, bw and ba at 16th week. sire also affected (p

Estimating microsatellite based genetic diversity in Rhode Island Red chicken

This study aimed to estimate microsatellite based genetic diversity in two lines (the selected RIRS and control line RIRC) of Rhode Island Red (RIR) chicken. Genomic DNA of 24 randomly selected birds maintained at Central Avian Research Institute (India) and 24 microsatellite markers were used. Microsatellite alleles were determined on 6% urea-PAGE, recorded using GelDoc system and the samples ...

a contrastive study of rhetorical functions of citation in iranian and international elt scopus journals

writing an academic article requires the researchers to provide support for their works by learning how to cite the works of others. various studies regarding the analysis of citation in m.a theses have been done, while little work has been done on comparison of citations among elt scopus journal articles, and so the dearth of research in this area demands for further investigation into citatio...
