Reduction in footpad dermatitis
Footpad dermatitis (FPD) is one of the most frequent problems that occur in broiler chicken farms today. It is characterized by lesions on the feet of poultry, which can vary in size and severity. There are a number of reasons that can influence whether or not birds show incidence of FPD. The main single factor is the corrosive effect of wet or damp litter resulting from high amounts of liquid faeces. Therefore, besides water provision, stocking density, climatic conditions and ventilation, feed ingredients play an important role in the triggering of FPD.
Typical SBM contains 4.5-10% indigestible galacto-oligosaccharides (maily raffinose and stachyose), which are unable to be digested by birds, Thus, soy oligosaccharides pass through the small intestine undigested and increase passage rate and luminal fluid retention. So, such indigestible carbohydrates exert an osmotic effect in the gastrointestinal tract until they are fermented. However, the fermentation capacity in the chicken intestine is limited and, consequently, part of these oligosaccharides is not fermented, triggering the above mentioned osmotic effect. The higher osmotic effect makes the digesta watery, which reduces its transit time in the gastrointestinal tract of the chicken, increasing the excretion of liquid feces and the humidity of the litter, clearly FPD predisposing factors.
A series of trials conducted by Hamlet Protein in several feeding regimes, all replacing some SBM with enzyme-treated protein (with an extremely low oligosaccharide content) have shown that Hamlet Protein offers a reliable option for reduction of footpad dermatitis incidence and severity.
