We have seen a 25%.50% reduction of the nº of birds affected by footpad dermatitis after a program with essential oils that target gut health. The trials have been made with broilers raised on rice husk litter.

Hi:Aside from material be used for litter that must have enough capacity to absorb water from faeces and waterer, enteritis and feed passage will exacerbate the bacterial growth and ammonia gas in house that induces footpad dermatitis. Hence management of gut health will be effective in preventing footpad dermatitis. Therefore, not only essential oil but also other product like prebiotic can be ef ...

The parents of broilers are defined as broiler breeders. In contemporary poultry industry practices, there are many selection criteria for broiler breeders. Beyond selecting for future broilers, maximizing broiler breeder characteristics (i.e. reproductive success) is also important. In essence, we are not only selecting for future broilers but future broiler breeders (grandparents, parents) as we ...

When an animal is infected by a pathogen, an immune response involving immune cell and immune molecule activity is stimulated and sickness behavior results.Sick chickens are difficult to identify because they rarely show signs of illness before it becomes severe. As a prey species, chickens are stoic ...

As the production systems become complex and the flock sizes increase, conventional welfare assessment methods can be inadequate. Technology can help us in that regard by reliably measuring behavioral and physiological indicators of welfare. In the recent years we have ...

Northern fowl mites (Ornithonyssus sylviarum) are one of the more common ectoparasites (external parasites) that can be present in a flock. These mites live on their host throughout their life and feed on poultry blood. They are most commonly found around the vent, tail, and breast of the birds. Although these mites prefer poultry as a host, they will move onto humans and will bite if trapped (for ...

Thanks for coming up with this interesting idea and article.At this point, I guess it is important to stress that, on the one hand, we create better conditions for animal welfare, reduce stress, cannibalism, some metabolic problems, including carcass alterations, leg problems, wooden breast syndrome (in the case of broilers). On the other hand, we significantly increase the risk of bacterial (salm ...
