الملخص EN

Feed additives are defined as products used in animal nutrition for improving the quality of feed or the animals’ performance and health.

Feed additives are “Non_nutritive substances added to feed to improve its efficiency of utilization and acceptance, metabolism and health of the animal”.

Feed additives are the substances that are added to the feed and don’t have any nutritional value.

Before the addition of additives to the diet, their adverse effects are checked by continuous experimentation.

They are added to ruminant feed to enhance digestion, promote growth, increase palatability, and maintain rumen environment etc.

Additives have their biological and economic benefits.

According to the increasing human population in the world which reached about seven billion people and it continuously increases.

In this background, the food source of both animal and plant origin must be accordingly increased.

Therefore, we must use and add some feed additives such as antibiotic, probiotic, prebiotic, post biotic and synbiotic for the animal feeds to increase production (meat, egg, milk and fish) and improve health.
