Fibre plays a supporting role in poultry nutrition

Dietary fibre is the part of plant material consisting mainly of cellulosic and non-cellulosic polysaccharides, and a non-carbohydrate component, lignin. These components are highly resistant to hydrolysis by alimentary enzymes and cannot, therefore, be digested or absorbed in the blood stream. Yet fibre plays an important role in poultry diets, if applied properly.

By Dr Salah H. Esmail , Cairo, Egypt It is generally believed that fibre content of feedstuffs is associated with their bulkiness. In some cases, however, there is no marked relationship... read more »

How nutrition affects immune responses in poultry

Nutrient recommendations, such as those set by National Research Council (NRC) of the United States, are usually based on the needs of healthy birds under ideal management, and require adjustments for practical production situations. Attention should be given to those nutrients that are associated with the development of the immune system. read more >

Involvement of calcium and phosphorus in bone and shell quality of early maturing commercial layers

Leghorn strains are continuously changing to meet market demands. The age of maturity in commercial pullets has steadily decreased, and egg output and case weights continue to increase. Consequently, nutritional management also needs to change to meet the genetic potential of the new strains. When new genetic lines are introduced, issues such as calcium and phosphorus management need to be constantly evaluated. read more >

The use of essential oils and their compounds in poultry nutrition

Essential oil blends should be regarded as one of the tools available to animal nutritionists in formulating diets for poultry. Further research is continuing to develop our understanding of the real potential of these products. read more >

Discovering alternatives to antibiotics - Where do we go from here?

New strategies for the control of the microbial/immune and immune/ nonlymphoidal interfaces are critical in discovering alternatives to antibiotics as growth promoters. These strategies must not result in resistant microbes and must enhance or maintain immune function. read more >
