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...
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 Hinai-dori is a native breed of chicken from the Akita Prefecture in Japan. A cross between the Hinai-dori and Rhode Island Red breeds has been commercialized as the Hinai-jidori chicken, one of the most popular brands of chicken in Japan. Here, a method of discriminating between the Hinai-jidori and other chickens is described. Individuals (555) of the Hinai-dori breed were analyzed by usi...
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 ...
We compared the degrees of vitality 12 Korean native chicken breeds, such as Jaeraejong, Rhode Island Red (Rhode), White Leghorn, Cornish (Cornish), and Ogye breeds. The survival rate telomere length were measured vital markers. Telomere was analyzed via quantitative fluorescence in situ hybridization method using lymphocytes 466 chickens. found that decreased linearly with increasing chronolog...
