A total of 1,320 tracheal samples from 66 broiler flocks sent to slaughterhouses and 42 tracheal samples from 42 flocks of local chickens in the field were collected for infectious bronchitis virus (IBV) gene detection by reverse transcription polymerase chain reaction using nucleocapsid-specific primers and spike-specific primers. Prevalence in broiler flocks was 39.4% (26/66) and in local chi...

Avian intestinal spirochaetosis (AIS) is a disease complex affecting adult laying and breeding chickens associated with infection by anaerobic intestinal spirochaetes of the genus Brachyspira. Options for control of AIS are limited, as few effective antimicrobial agents are registered for use in laying chickens. One of the two most commonly encountered pathogenic species in AIS is B. intermedia...

Introduction and insects which can act as reservoirs or vectors for a range of bacterial and helmintic diseases( Permin Poultry outnumbers all other forms of livestock in et.al.,1997). A study on the incidence of worms in Nigeria, and, not surprisingly, are found throughout the chicken farms in Nigeria found that the most common country, wherever there is human settlement. Chickens species were...

Retail organic (n = 198) and conventional (n = 61) chickens were analyzed. Most organic (76%) and conventional (74%) chickens were contaminated with campylobacters. Salmonellae were recovered from 61% of organic and 44% of conventional chickens. All Salmonella enterica serovar Typhimurium isolates from conventional chickens were resistant to five or more antimicrobials, whereas most S. enterica...

Gross lesions characterized by swollen livers and spleens accompanied by diffuse white miliary spots, which resembled those of Marek's disease, were detected in two flocks of local meat-type chickens at a Japanese poultry processing plant in June and August 2010. The microscopic examinations revealed proliferative foci consisting of spindle or polymorphic cells in the interstitium of livers, sp...

In Experiment 1, chickens from various white leghorn experimental lines were inoculated with strain ADOL-Hcl of subgroup J avian leukosis virus (ALV-J) either as embryos or at 1 day of age. At various ages, chickens were tested for ALV-J induced viremia, antibody, and packed cell volume (PCV). Also, at 4 and 10 wk of age, bursal tissues were examined for avian leukosis virus (ALV)-induced prene...

Food independence is a reference for country in solving various problems related to the availability of necessities life people who do not depend on other countries, especially livestock sector. Prioritizing development local such as native chickens producers food products animal origin, able answer challenges world husbandry it today. This study aims to: (1) conduct an analysis factors that in...

This study aimed to examine local feed ingredients such as sorghum, cassava and whole sago the substitution of corn in ration through growth broiler chickens. The observed variables were consumption, final body weight, weight gain, conversion mortality during from 1-5 week age. experimental design conducted was a completely randomized with 4 treatments, namely commercial rations (P0), containin...

In the present study, we have explored the genetic relationships between red junglefowls and domestic chickens in Southeast Asia by using single nucleotide polymorphism (SNP) markers. We genotyped 475 individuals from 17 populations of red junglefowls (4 subspecies, n=39), native chickens (10 populations, n=346) and commercial breeds (3 breeds, n=90) using PCR-RFLP for the 98 autosomal SNP mark...

This study sought to assess mitochondrial DNA (mtDNA) diversity and phylogeographic structure of chickens from five agro-ecological zones of Zimbabwe. Furthermore, chickens from Zimbabwe were compared with populations from other geographical regions (Malawi, Sudan and Germany) and other management systems (broiler and layer purebred lines). Finally, haplotypes of these animals were aligned to c...
