Alphamune, a yeast extract antibiotic alternative, has been shown to stimulate the immune system, increase BW in pigs, and reduce Salmonella colonization in chickens. The influence of Alphamune on gastrointestinal tract development has not been reported. Two trials were conducted to evaluate the effects of Alphamune on gut maturation of 7- and 21-d-old turkey poults. Poults were fed a standard ...

Turkey poults were randomly placed in batteries and fed one of four dietary treatments: control (C); control plus 4ppm diacetoxyscirpenol (DAS); control plus 300ppm Fusaric Acid (FA); and control plus 4ppm DAS and 300ppm FA (FD). There were 10 poults per pen with 6 replicate pens per treatment. Individual BW, BW gains (BWG) and feed consumption by pen were determined at d6, d12, and d18. Period...

Commercial Australian White turkey poults, kept in small pens, were fed commercial diets until 8 weeks. Poults were then fed either 20 per cent dietary protein, with or without added lysine, or 24 per cent dietary protein, each with a metabolizable energy content of either 11.5 or 12.75 MJ/kg. The poults fed on the 24 per cent protein diet were heavier than those on the 20 per cent protein diet...

The effectiveness of an injected caprine serum fraction-immunomodulator (CSF-I2) as an immunostimulant in male and female F-line and commercial turkey poults infected with fowl cholera (Pasteurella multocida) was examined in separate trials. In the first 2 of 3 controlled trials, the effects of an i.m. injection of CSF-I2 given 24 h prior to a P. multocida challenge, administered by s.c. inject...

Globalisation and international trade facilitate the rapid spread and transmission of foodborne pathogens. This study was designed to determine the serovars, distribution of virulence genes (invA, avrA, ssaQ, mgtC, siiD, sopB, gipA, sodC1, sopE1, spvC, bcfC) and antibiotic resistance profiles in salmonellae recovered from imported and domestic day-old turkey poults in Egypt. The prevalence of s...

This study was conducted to test the effects of dietary supplementation of feed grade L-Met on growth performance and redox status of turkey poults compared with the use of conventional DL-Met. Three hundred and eighty five newly hatched turkey poults were weighed and allotted to 5 treatments in a completely randomized design and the birds were fed dietary treatments for 28 d, including a basal...

As effective probiotic Bacillus isolates that can increase BW gain (BWG) are identified, they may offer advantages in terms of stability, cost, and feed application over probiotics limited to drinking water application. Additionally, an effective direct-fed microbial (DFM) may offer an effective alternative to antibiotic growth promoters. Previously, 4 Bacillus isolates were identified and eval...

Bordetella hinzii is commonly acquired from the respiratory tract of diseased poultry but is generally regarded as nonpathogenic in avian hosts because attempts to demonstrate disease following experimental infection of chickens and turkeys have failed. Recently, with the availability of highly specific DNA-based methods for identification of this agent, it was recognized that some isolates use...

Turkey astrovirus type-2 (TAstV-2), turkey rotavirus (TRotV), and turkey reovirus (TReoV) have been implicated as possible causes of enteric diseases and poor production in turkeys; however, numerous studies with each individual virus have failed to reproduce the disease as observed in the field. Therefore, in this study we evaluated the pathogenesis of all possible combinations of one, two, or...

Introduction: Routine surveillance samples disclosed seropositivity to influenza A virus (IAV) in a Norwegian turkey breeder flock. Simultaneous reports of influenza-like symptoms in farm workers and a laboratory confirmed influenza A(H1N1)pdm09 (H1N1pdm09) infection in one person led to the suspicion of a H1N1pdm09 infection in the turkeys. Animals and methods: H1N1pdm09 infection was confirme...
