Introduction Feed supply is important for animal production and any factor that affects the security of the feed supply is a significant constraint to production. Feed spoilage by moulds may result in heating, reduced palatability and the loss of nutritive value (Christensen, 1974). In addition, the affected commodity may become contaminated with mycotoxins. The biological reactions following ingestion of one or a...

Introduction
Moulds and their toxins in feed are an increasing global challenge, and multiple environmental and pre-harvest and post-harvest agricultural practices may contribute to this increase. Mouldy feed and mycotoxins have been associated with lower feed intake, reduced digestibility and health disorders in ruminants. An array of mycotoxins can be present in mouldy silage, some of which are not normally...

INTRODUCTION In Cameroon, the production of sorghum is mostly done in the soudano-sahelian zone on approximately 300.000 hectares for an average production of 100.000 tons. This places the northern region of Cameroun on the first rank for cereal production within the sub region of Central African countries. Sorghum also occupies an essential place as food for millions of Cameroonians. The good image of the sorghum in the...

As producers, nutritionists and veterinarians we are used to seeing molds on the farm. Molds are ubiquitous in the environment and it has been well documented that some of these molds have the ability to produce poisons known as mycotoxins. Because of their ability to survive many environmental conditions, different species of molds have the ability to grow on the crop in the field pre-harvest, during harvest and also post harvest. It has also been documented that mycotoxin...

INTRODUCTION Livestock industry in West Africa has seen a tremendous growth with the best application of nutritional technologies (John Prabakaran and Dhanapal, 2009). However, feed safety is a concern for achieving productivity (Jimoh and Kolapo, 2008). Even with the best quality control systems in the world, animal producers often find themselves owning mycotoxin contaminated grains or...

Introduction The primary objective in fish nutrition is to provide a nutritionally balanced mixture of ingredients to support the maintenance, growth, reproductive performance, flesh quality and health of the animals at an acceptable cost. The diet should also have a minimal effect on water quality and culture systems. In order to achieve these goals the diet must provide all required nutrients in the correct balance and must be formulated to keep any anti-nutritional...

The fungus Aspergillus flavus causes Aspergillus ear rot, one of the most important diseases in corn. The fungus produces a mycotoxin — known as aflatoxin — inside the diseased corn kernels. The presence of aflatoxin will affect grain quality and marketability, as well as livestock health if the grain is consumed. Aspergillus ear rot is commonly observed during hot, dry years on stressed plants (such as those exhibiting symptoms of...

With high temperatures and dry conditions being prevalent during this season's corn grain-fill period, the risk of Aspergillus ear rot is high. Caused by the fungus Aspergillus flavus , Aspergillus ear rot is observed as a yellowish-green mold growing on corn kernels. Areas in fields that have insect- and bird-damaged ears may be affected more severely by the disease. Aspergillus flavus produces a mycotoxin known as aflatoxin,...

Microbial deterioration of grain, feedstuffs and animal feed is of great concern to all segments of the production animal industry. Molds are a group of microorganisms that cause deterioration of grains or feeds, various infections in livestock and intoxication due to the formation of mycotoxins in feedstuffs. It is reported that as much as 25% of the world's cereal grains may be contaminated with mycotoxins. Since mycotoxin production and feedstuff...

Aflatoxins are a group of chemicals produced by certain mold fungi. These fungi, Aspergillus flavus and Aspergillus parasiticus , can be recognized by olive green or graygreen, respectively, on corn kernels, in the field or in storage (Figure 1). Although aflatoxins are not automatically produced whenever grain becomes moldy, the risk of aflatoxin contamination is greater in damaged, moldy corn than in corn with little mold. Aflatoxins are harmful or fatal to...

The significant research focus on mycotoxins in recent years has dramatically increased our awareness and understanding of mycotoxin nature, occurrence and impact on modern animal production. Mycotoxins in feedstuffs represent an unavoidable risk due largely to environmental factors. As a result, analytical tools using a holistic approach are needed to understand multiple mycotoxin contamination patterns. Application of Alltech's 37+ Program...

Introduction Paddy harvesting, threshing and its storage are major agricultural activities in south Asia during the November. Such rice straw is the major fodder for cattle and buffaloes during winter lean period. It´s a fact that rice production needs source of water supply for irrigation as water is indispensable throughout production period. The rice straw should be properly dried before feeding otherwise the undried straw might...

Grain infected by mold may contain toxic fungal metabolites called mycotoxins. The word mycotoxin was derived from mycotoxicosis, which was a term first used in 1955 to describe diseases of animals caused by fungal toxins. The presence of mycotoxins in feed grains or ingredients may cause illness or death in livestock. Mycotoxins also pose a potential hazard to human health. The Food and Drug Administration (FDA) has established an action level of 0.5 parts per billion (ppb) of the...

How feed can be protected from being infected from moulds? can any temperature treatment help? and how can we diagnose that feed grains are infected with moulds? Is there any specific laboratory tests that may guide us? I wil be very thankful if you people help me more about how to protect feed ingredients from being infected with moulds and how should i get checked my feed for this purpose. Thanks, Dr. Syed ...

Mycotoxins are metabolites produced by molds (fungi) which are toxic when consumed in significant amounts by livestock. The resulting pathological syndromes are referred to as mycotoxicoses. Mold growth on grains and subsequent mycotoxin synthesis is regulated by numerous factors of which moisture content is usually the most important. Toxigenic fungi generally grow best under humid, warm, aerobic conditions. High moisture grains are, therefore, particularly susceptible to...

The occurrence of toxins can be classified into different groups. The most frequent occurring toxins are those produced in feed grain. These toxins can be divided into toxins formed before harvest and toxins formed after harvest. Toxins can also occur in different protein sources such as soy-, rapeseed- and sunflower products. FAO estimates that about 25% of the world's crops production contains toxins. There is a big...

The global frequency of mycotoxin contamination of feedstuffs and the severity of mycotoxicosis in livestock has increased in recent years. Wheat-based feed and food supply chains can be contaminated with mycotoxins produced by a variety of fungi, in particular by Fusarium species. Since wheat is an important source of energy in human nutrition and in nutrition of monogastric animals its quality is crucial. This paper gives an overview of the occurrence...
