Product title :

Protein nutrition for ruminants in European countries, in the light of animal feeding regulations linked to bovine spongiform encephalopathy

Author(s) : P. Sellier

Summary :

The outbreak of bovine spongiform encephalopathy (BSE) and the discovery of the central role played by meat-and-bone meal (MBM) as the vehicle of infection resulted, from the late 1980s onwards, in the implementation of new regulations on the incorporation of animal proteins, and then of most fats of animal origin, into diets fed to ruminants and other farmed animals. The BSE-related feed ban, which has gradually been reinforced over time, has led to the investigation of cost-effective routes for adequately replacing MBM and tallow by new sources of dietary proteins, minerals and lipids in the formulation of manufactured concentrates. As far as the technical fulfilment of the nutritive requirements of growing and lactating ruminants is concerned, efficient alternative solutions, based principally on recourse to food materials from vegetals already exist or hopefully will soon be available in most of the situations prevailing in Europe. However, related aspects, such as animal feed-processing, availability and traceability of certain food materials, quality of animal products, environmental constraints or disposal of animal waste from the meat industry give cause for concern. The expected consequences of the BSE-related feeding regulations on the organisational and economic framework of animal and crop production sectors throughout Europe and at world level must also be evaluated.
