Efficacy Of Live Infectious Bronchitis Vaccine Programs Against Infection By Qx-Like Strain Of Infectious Bronchitis Virus, Ekasingh Sarueng, Wisanu Wanasawaeng, Jiroj Sasipreeyajan, Niwat Chansiripornchai

The Thai Journal of Veterinary Medicine

The aim of this study was to evaluate the efficacy of live infectious bronchitis (IB) vaccine programs against infection by a QX-like strain of the IB virus isolated in Thailand. The experimental groups were divided into 5 groups. Group 1 broilers were administered with Poulvac IB QX-like at 1 day old. Group 2 broilers were administered with Poulvac IB QX-like at 1 and 14 days old. Group 3 broilers were administered with Nobilis IB H120 and Poulvac IB QX-like at 1 and 14 days old, respectively. Group 4 broilers were administered with Nobilis IB H120 and Nobilis IB 4-91 at …

The Effectiveness Of Vaccination With Two Live Infectious Bronchitis Vaccine Strains Against Qx-Like Infectious Bronchitis Virus Isolated In Thailand, Tawatchai Pohuang, Niwat Chansiripornchai, Achara Tawatsin, Jiroj Sasipreeyajan

The Thai Journal of Veterinary Medicine

The purpose of this study was to evaluate the level of protection generated by vaccination with 2 live attenuated vaccine strains against QX-like infectious bronchitis virus (IBV) isolated in Thailand. Eighty-four 1-day-old broiler chickens were randomly allocated into 6 groups with 14 chickens in each group. Groups 1-4 were vaccinated with different vaccination programs against IBV. Groups 5 and 6 did not receive any IBV vaccine and served as positive and negative control groups, respectively. At 1 day old, the chickens in groups 1 and 4 were vaccinated with H120 vaccine whereas the chickens in groups 2 and 3 were …


Study On The Relationship Between Single Nucleotide Polymorphisms Of The Coccidiosis-Resistance Candidate Zyxin Gene Exon 1 And Carcass Traits In The Jinghai Yellow Chicken, Guojun Dai, Dahui Sun, Mingming Sun, Yuxin Lin, Xiang Wang, Genxi Zhang, Kaizhou Xie, Miaomiao Shi, Olajide Olowofeso, Jinyu Wang Jan 2014

Study On The Relationship Between Single Nucleotide Polymorphisms Of The Coccidiosis-Resistance Candidate Zyxin Gene Exon 1 And Carcass Traits In The Jinghai Yellow Chicken, Guojun Dai, Dahui Sun, Mingming Sun, Yuxin Lin, Xiang Wang, Genxi Zhang, Kaizhou Xie, Miaomiao Shi, Olajide Olowofeso, Jinyu Wang

Turkish Journal of Veterinary & Animal Sciences

Previous research revealed that several single nucleotide polymorphisms (SNPs) of zyxin were significantly associated with coccidiosis-resistance parameters. In this research, the Jinghai yellow chicken was chosen to detect the SNPs of zyxin gene exon 1 by PCR-SSCP and DNA sequencing techniques, and was also used to analyze the effect of zyxin SNPs on carcass traits. A single mutation was found with 3 genotypes, designated as AA, AB, and BB. The results showed that BB was significantly different from AA and AB in terms of abdominal fat weight and slaughter rate for cockerel (P < 0.05), while there was no significant difference between AA and AB (P > 0.05). The heart weight, breast muscle rate, …
