The hypoxia adaptation to high altitudes is of considerable interest in the biological sciences. As a breed with adaptability to highland environments, the Tibetan chicken (Gallus gallus domestics), provides a biological model to search for genetic differences between high and lowland chickens. To address mechanisms of hypoxia adaptability at high altitudes for the Tibetan chicken, we focused o...
The aim of this work was to seek a different approach to conserving important domestic animals in imminent danger. A Qingyuan partridge chicken embryonic fibroblast line, containing 336 cryovials with 8x10(6) cells each, was successfully established from 60 Qingyuan partridge chicken embryos using explant culture and cryopreservation techniques. The cells were morphologically consistent with fi...
A QTL involved in the primary antibody response toward keyhole limpet hemocyanin (KLH) was detected on chicken chromosome 14 in the experimental population, which was created by crossing commercial White Leghorn and a Polish native chicken breed (green-legged partridgelike). The current QTL location is a validation of previous experiments pointing to the same genomic location for the QTL linked...
This study evaluates the growth performance, body linear parameters and egg quality of Yoruba ecotype chicken their F1 F2 crosses using Lohmann brown cocks under a low-input management system. Ten were mated with thirty indigenous hens to obtain progenies. also back Also, ten male 30 female as basis for comparison. Mating was done at 1:3 in all groups. Incubation hatching naturally properly mon...
Poultry products are an important source of Salmonella enterica. An effective way to reduce food poisoning due to Salmonella would be to breed chickens more resistant to infection. Unfortunately host responses to Salmonella are complex with many factors involved. To learn more about responses to Salmonella in young chickens of 2 wk old, a cDNA Microarray containing 13,319 probes was performed t...
Aseel and Naked neck are major chicken breeds of the tropics well-known for their thermotolerance robustness. However, both them especially very susceptible to Avian Influenza (AI) which cause huge mortalities. The role cytokines in relation pathology severity disease caused by endemic strain (H9N2) AIV these remained thus far unclear. aim this study was investigate effects H9N2 on expression l...
Phenotypic Performance and The Characterization of Growth Hormone (GH|AluI) in Bangkok Chicken Breed
This study aimed to determine Bangkok chicken’sphenotypic characteristics and growth hormone genes using the PCR-RFLP method. The samples used were 50 chickens. Research in field is taking phenotypic traits data. laboratory carried out by DNA isolation, amplification, restriction. showed that DOC weight,body weight, bodyweight gain of DOC-1 month, 1-2 months, 2-3 months chickens significantly d...
