Mycotoxins in poultry
Common mycotoxins associated with mycotoxicoses in poultry include aflatoxins, fumonisins, zearalenone, ochratoxins, and trichothecenes such as deoxynivalenol and T-2 toxins. Diagnosis requires detection and quantification of the specific mycotoxin. Treatment includes removal of the source of the mycotoxin and supportive care. Mold mitigation strategies can be used for prevention. Mycotoxicoses are diseases caused by the poisonous effects of the toxins produced by filamentous microfungi (ie, toxigenic molds). Hundreds of mycotoxins are known and can produce mild to severe toxic effects when they occur above levels of concern. The importance of mycotoxin problems in poultry is probably considerable yet difficult to measure. Chronic low levels of exposure to more than one type of mycotoxin appears to be a commonality, yet is less clinically evident.
INTRODUCTION Agric Trade business in Day Old Chicks( DOC) and value chain products is still poorly developed in the West Africa sub region, and must be strengthened in order to contribute and impact on the intra regional agricultural business and trade movement in other to increase poultry food security in the region in line with the presidents Global Food security Response (GFSR). ...

The Livestock Industry Foundation for Africa has been very proactive in educating rural and peri-urban farmers about mycotoxin and its effects on livestock production in Africa. The organization discussed at Ogun State with farmers and hatchery operators about the role the mycotoxins play in the quality of their day old chicks.
The topic was "Day old chick health status and early mortalities: consequences of mycotoxins on breeder...

Introduction Worldwide, necrotic enteritis (NE) leads to important production losses, increased feed consumption and mortality rates, and a reduced welfare of broiler chickens [1–4]. The causative agent of NE is Clostridium perfringens, a Gram-positive spore forming bacterium which occurs ubiquitously in the environment, in feed and in the gastrointestinal tract of animals...

1. Introduction Aflatoxins, which are secondary metabolites produced by the Aspergillus flavus and parasiticus species of mold, are among the most potent natural carcinogens. No animal species is immune to the toxic effects of consuming food contaminated with aflatoxin and Aspergillus species are known to infect important agricultural crops. Therefore, in cases where preventative management strategies in...

At the conclusion of the 9th World Mycotoxin Forum and the 14th IUPAC International Symposium on Mycotoxins -that took place last June at Winnipeg, Canada-, this were the main lessons learned, as explained by General Conference Chairs Rudolf Krska and Hans van Egmond, and the session chairs.
1st lesson: We are living in a changing world
• Changing world = changing technology, changing mycotoxin patterns, diverse dietary...

Pancosma & Associates released its annual mycotoxin survey, in partnership with Labocea, covering 1740 raw material and animal feed samples, evaluating the risk posed to livestock animals by 46 different mycotoxins, mainly in Europe. The comprehensive analysis extended beyond simply detecting contamination, to take into account the differing levels of sensitivity across various animal species. The data gathered show large variations in levels of mycotoxin...

Introduction Mycotoxins are secondary fungal metabolites, whose presence in feed and foodstuffs. Ochratoxin A (OTA) is one of the most known mycotoxins with greatest public health and agro-economic significance (Duarte 2011). Whereas, OTA is considered a potent nephrotoxic and hepatotoxic effects (Stormer and Lea, 1995). In commercial birds, consumption of OTA-contaminated diets has been related to clinical signs of...

Hello, These lesions appear in broilers beginning with 20 days of age. It is random and exclusive to 30% of the farm not 100%. Initially I thought the black content (found in the gizzard and in the crop, until the duodena, but not in the cecum) was digested blood. Now I don't know what to think. The chick are not eating, not drinking, first with low mortality, now more... the feed is from the same place as all the farm, and every one is from the same hatchery,...

Mycotoxins are a large group of toxins produced by moulds and they can be very toxic for animals, plants and humans. To date we know of approximately 300 different mycotoxins and data from the UN has shown that mycotoxins are present in more than 30% of the cereals produced worldwide. The challenge with mycotoxicosis is that it is very difficult for the producer to clearly diagnose. However, every poultry producer knows that mycotoxins...

Introduction There has been a steady increase in the poultry meat and egg production globally during the past few decades. Though the high biological value of eggs and poultry meat have resulted in an increasing demand for these two products, growing awareness for food quality and safety are becoming increasingly significant in determining the market value. The importance of mycotoxins as one of the major detractor of...

It has been known for decades that aflatoxin B1 severely depresses the growth rate and viability of poultry species with younger animals being most susceptible. Intensive investigations since that time have demonstrated that certain phyllosilicates, usually addressed as hydrated sodium calcium aluminosilicates (HSCAS), have the ability to bind aflatoxin B1 and alleviate clinical symptoms of aflatoxicosis. The purpose of this experiment was to test the...

1. Introduction Avian mycotoxicosis refers to all the diseases caused by the effect of mycotoxin in birds. These diseases may not be pathognomonic and sometimes subclinical and difficult to diagnose. The problem is worldwide but effort will be made to localise the effect of these diseases in developing countries. Developing countries have more than 50% of total meat and egg production in global poultry market: [1]. The...
