In an attempt to determine the seroprevalence of avian leukosis virus (ALV) in exotic broiler chickens and Nigerian local chickens in Zaria, Nigeria, a total of 600 sera (300 from exotic broiler chickens and 300 from Nigerian local chickens), obtained from the live bird market in Zaria, Nigeria, were tested for ALV p27 antigen by the antigen capture enzyme linked immunosorbent assay (ac-ELISA) ...

The rearing of large numbers of broiler chickens at geographically dispersed sites means that they have to be transported by road, over various distances, to centralized processing plants for slaughter. The birds may be exposed to a variety of stressors during transit, including the thermal demands of the transport microenvironment. The thermal environments experienced by broiler chickens durin...

the objective of this study was to find a relationship between blood gas parameters and thyroid hormoneactivity with ascites syndrome in broiler chickens exposed to cold temperature and receiving a high qualitydiet. one hundred and sixty one-day-old broiler chicks were randomly divided in two equal groups. toincrease the incidence of ascites, chicks of group 1 were fed ad libitum with a higher ...

In 2003, Brazil was recognized as a pathogenic Newcastle Disease Virus (NDV) strain-free country for commercial poultry. This research was conducted in Brazil between December 2003 and March 2005 to verify the maintenance of this virulent NDV-free status. Serum samples from 5,455 flocks for commercial poultry farms were collected, comprising 81,825 broiler chickens. The farms were located in ni...

Pulmonary hypertension syndrome (PHS), commonly called ascites, is a costly metabolic disease occurring in rapid-growing chickens. Research has shown that dietary sources of energy (KHAJALI and FAHIMI, 2010) and protein (IZADINIA et al., 2010) have significant effects on pulmonary hypertensive response in broiler chickens. It has been suggested that rapid-growing broilers may be in the status o...

The results of this study constitute a part of a project aiming at developing a cross-breed suitable for an extensive rearing system, utilising local biodiversity. Hybrids from mating a commercial broiler’s male component (C) with Green-legged Partridgenous (GP) or Sussex (Sx) hens were compared with Cobb broilers. The study included 720 chickens of 3 genetic groups. Up to the third week of age...

The aim of this study was to determine the presence of genes coding for alpha (cpalpha), beta (cpbeta), epsilon (epsilontx), iota (iotaA), enterotoxin (cpepsilon) and beta2 (cpbeta2) toxins in Clostridium perfringens isolates from broiler chickens and parent broiler breeder hens, using multiplex polymerase chain reaction (PCR) assay. The prevalence of C. perfringens in the intestinal segments a...

The objective of this experiment was to assess the use of different vitamin D metabolites in the feed of broiler chickens and the effects of the metabolites on performance, bone parameters and meat quality. A total of 952 one-day-old male broiler chicks were distributed in a completely randomised design, with four treatments, seven replicates and 34 birds per experimental unit. The treatments c...

The aim of the study was to determine effect Cu and Zn chelates on levels these microelements in blood broiler chickens successive weeks rearing. re-search material Ross 308 chickens. carried out two buildings with 30,000 each. From each building, 50 were randomly selected form experimental control groups. Blood for analysis collected from wing vein every 7 days, first day fattening 42. In grou...

This study was designed to evaluate the occurrence of Clostridium difficile in both broiler chicken farms and packed chicken parts sold at market places in Mashhad, the second most popular Islamic pilgrimage city after Mecca in northeastern Iran. The fresh faecal samples were obtained from broiler farms, while the chicken packs were purchased from retail outlets across the city at market places...
