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.
Poultry, swine and dairy producers admit today that the presence of mycotoxins in the feed is one of the main factors affecting animal production. As a result of the higher prices of feed ingredients, their quality is getting worse, with some grains showing higher levels of mycotoxins. High contamination levels can also be found in distillers grains, an ingredient in increasing supply, originated from the use of corn in ethanol production in the US. Some producers consider that...

Introduction The presence of mycotoxins in feed grains is rious for both broilers and broiler performance. In order to reduce the negative effects of mycotoxins in animals, mycotoxin-adsorbing additives with different neutralization abilities are used. The purpose of this study was to determine the in vitro aflatoxin-adsorbing ability of T5X SD in broilers. ...

Introduction Anti-nutritional factors depress nutrient quality of the feed and hence the health and performance of poultry. Mycotoxins are one such anti-nutritional factor present in feed ingredients and complete feed. They are the secondary toxic metabolites produced by various genera of fungi. Fungi that produce mycotoxins of major significance in the poultry industry include Aspergillus, Fusarium and Penicillium. Though hundreds of mycotoxins have been implicated in animal...

1.- HT-2 toxin and trichotecene mycotoxins
The HT-2 toxin belongs to the group A of the trichotecene toxins. These mycotoxins are produced by molds of the genus Fusarium , such as, Fusarium tricinctum, F.nivale, F.roseum, F.graminearum, F.solani, F.oxysporum, F.lateritium, F.sporotrichioides, F.rigidiusculum, F.episphaeria and F.poae . Other molds also can produce trichotecene...

FIGAP 2026: The Scientific And Technological Exhibition Of The Livestock Industry
Suggested link
Days ago, the XXIII edition of the World Poultry Congress was held in Queensland (Australia), organized by the World Poultry Science Association (WPSA), with the main objective of promoting researching and scientific and technical exchange among top specialists and professionals of the poultry industry, and currently being one of the most active and renowned organizations globally. At this time, it counts on more than 7,000 members, all of them technicians, professionals and...

This work was conduced to determine the performance parameters of initial-phase turkey poults fed 7 different doses of aflatoxins in the diet. Three hundred thirty-six 1-d-old male turkey poults were used in this research. Turkeys were divided into 7 treatments according to aflatoxin doses (T1 = control; T2 = 20 ppb aflatoxins; T3 = 50 ppb; T4 = 100 ppb; T5 = 200 ppb; T6 = 500 ppb; T7 = 1,000 ppb). Birds were killed in 2 periods: half of them after 21 d of experiment and the remaining birds...

Mycotoxins are fungal metabolites that can reduce performance and alter metabolism of livestock and poultry (Wannemacher et al., 1991). The pathological states arising from the consumption of feeds contaminated with mycotoxins are termed mycotoxicoses. Mycotoxins can be formed in the field preharvest and may continue to be formed under suboptimal storage conditions postharvest. High moisture content often predisposes feedstuffs to fungal growth and mycotoxin...

The immune system is the defense mechanism of the body of which key organs are thymus, bursa, liver and spleen. In poultry bursa of Fabricius (located in the lower back of the chicken) and thymus (in the neck) are key sites for immune responses and hence termed as chief immune organs. It is common...
