INTRODUCTION

Our principal question is the following: do any of the food energy assessment systems predict the availability of energy from a high fiber submaintenance diet? Weeight most of the studies investigating the effect of PKM inclusion in broiler diets, PKM has been included into a control diet either at the expense of an ingredient usually the major cereal in the diet with the consequence of decreased nutrient density or without considering the AA digestibility of PKM.

The content of non-starch polysaccharides in different cereals and their physicochemical yoj Cereals such as wheat, triticale, barley, maize, and rye commonly used in animal nutrition are not only a source of valuable nutrients but also of reducing digestibility - NSP. Nahas J. The lower body weight gain may led to increasment of the feed intake in order to compensate worse nutrients availability. These compounds play an important role as energy sources for both ruminant and monogastric animals. Lazaro et al. Non soluble NSPs — Encapsulate all other nutrients rendering them undigested. Effects of xylanase and glucanase addition on performance, nutrient digestibility, and physico-chemical conditions in the small intestine contents and caecal microflora of broiler chickens fed a wheat and barley- based diet.

Summing up, the spectrum of action of NSPases is multidirectional. What is more, SCFA reduce the number of pathogenic bacteria by lowering the pH value of the gastrointestinal tract, which creates unfavourable conditions for their proliferation, while such an environment favours the development of commensal anaerobic population. The lower body weight gain may led to increasment of the feed intake in order to compensate worse nutrients availability. Similar findings were reported by Mendes et al. Cereal Sci.

Also, using different analytical methods for the same feed material results in different data Bach Knudsen, In this experiment feed intake, number and size of jejunal goblet cells and spleen weight were not affected by the rye inclusion. Effect of storage time and dietary enzyme on the metabolizable energy and digesta viscosity of barley-based diets for poultry.

They include cellulose, pectins, gums, glucans, inulin, chitin exclude lignin. Another advantage that puts rye in a better light than in the past is its price, as it is also currently the cheapest raw feed material.

In addition, production costs are reduced in comparison to the other cereals due to lower use of chemicals, calcium and fertilisers. It was also shown that in a rye-based diet the type of fat is able to influence the digesta pH and effectiveness of NSP- degrading enzymes - probably due to microbial activity Danicke et al.

Slominski B. They limit the non starch polysaccharides in poultry diets that make you lose weight of digesta viscosity through the hydrolysis of plant soluble polysaccharides, promote the proliferation of beneficial microflora yo by providing substrates for fermentation, increase nutrient availability, thus improving the nutrients value of NSP-rich cereals, increasing poultry performance and reducing the cost of production. There is also no doubt that a higher ileal viscosity level, which slows down the gastric passage rate and leads to deterioration of digestion, has a negative effect on intestinal microbiota as undigested nutrients become a breeding ground for pathogenic bacteria. The genetically determined contents of polysaccharides were investigated by Cyran and Lapinskiwho reported that the content of AX is almost halved in tetraploid triticale cultivars compared to hexaploid cultivars. Such findings confirm that NSP are responsible for a higher ileal viscosity level.
