this study was conducted at beresa watershed district of guraghe administrative zone, the southern regional state of ethiopia to evaluate the on-farm reproductive and egg production performances of local kei and its f1 crosses with fayoumi and rhode island red (rir) chicken breeds under farmers’ management. the local kei paternal line was mated with maternal lines of fayoumi and rir chickens to...

The objective of this study was first to investigate the prevalence of poultry coccidiosis and to identify the coccidial species occurring in the study area on local strain and Rhode Island Red breed chicken. The study involved questionnaire survey, fecal examination, necropsy examination and identification of coccidial species based on their morphology, predilection site in the intestine and s...

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 ...

This study aimed to characterize production and reproduction performances in Rhode Island Red-White strain chicken developed and maintained at the Central Avian Research Institute, Izatnagar. Three hundred and forty six fertile eggs were set in automated electric incubation and 234 chicks were investigated in three hatches. The performance data was analyzed by least squares analysis of variance...

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 ...

the aim of this study was to investigate the range utilization of rhode island red hens, grazing outdoor (under tropical conditions) and to scan their activities inside the house as well as during their outdoor visits. the activities of rir hens, raised in indoor floor pens connected with outdoor areas covered with natural vegetation, were scanned and recorded individually within 15 minute inte...

Poultry farming not only provides high nutritious food but also creates employment opportunity for rural masses. Documented evidences elaborates that helminth parasitism is most deciduous problem of chickens especially in developing world. Ascaridia (A.) galli, a nematode of small intestine, has been considered as the most common and important parasite of chicken. The present study was carried ...

Blood samples were collected from eight native Japanese breeds of chickens (Miyadi-dori, Ohiki, Onaga-dori, Shoukoku, Tosa-Jidori, Tosa-Kukin, Toutenkou and Uzurao) and two foreign breeds of chickens (White Leghorn and Rhode Island Red) to examine the genetic variability and relationships among the breeds by using a microsatellite DNA technique. Except for the Shoukoku breed, the other Japanese...

the objective of this study was to evaluate the effect of the sto feeder layer on prepubertal rhode island red rooster sscs culture and proliferation in vitro. testis cells from 30 prepubertal rhode island red chicken (4-8 weeks of age), were individually separated and cultivated in the presence of  bfgf and lif growth factors on four well plates with two treatments and three replicats and five...

This study aimed to estimate microsatellite based genetic diversity in two lines (the selected RIR(S) and control line RIR(C)) 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 samp...
