Extract

Biotechnology is the application of biological procedures and processes to manufacture and service industries (Armstrong, 1988). Any processes which require microorganisms (natural or genetically modified) or biological extracts should be related to biotechnology. Biotechnology has played a vital role in the production of novel products using a variety of microbes. These products have immense potential in improving not only the nutritive quality of crops (Chaudhry and Miller, 1994) but also utilization of food by animals. One such product is recombinant DNA-derived bovine somatotrophin (BST) which has been widely used for years to stimulate milk yield in dairy cows. However, its prolonged use adversely affects health, reproduction and birth weight and skeletal size of the offspring (Dr. Robert Cook, personal communication). Other products of importance are microbial cultures and purified enzymes. The cultures or enzymes are generally mixed with diets to enhance digestive efficiency of livestock by altering microbial activities in the rumen or gastrointestinal tract. They are safe to handle and kind to animals and environment (Dawson, 1992). Whilst biotechnology has a wide range of applications for livestock industry its role in ruminant nutrition is particularly emphasized.
