Abstract
Feed and nutrition play a crucial role in the quality and quantity of livestock
production, both ruminants and non-ruminants. As a result, the supply of feedstuff
resources has not met the needs of animal populations, which might lead to decreased
performance, poorer health, increased erosion, and overgrazing, which would increase
the number of livestock animals. To meet animal protein requirements, feed availability
with a low price containing high quality is a big challenge for nutritionists in the future
quality. Conventional methods were used to increase livestock improvements,
including livestock diseases, management, nutrition, genetics and breeding that resulted
in enhancing livestock production. Currently, these methods are no longer sustainable;
modern techniques, especially biotechnology, are required for optimum productivity.
Utilizing natural and organic resources, for controlling food-borne diseases, modern
biotechnology techniques are needed to implement the bitterness of the livestock
population, increasing food safety and reducing poverty for livestock farmers. Due to
advances in livestock nutrition, there has been a focus on enhancing livestock
requirements, to understand the demand and availability of the ingredients, and
composition and formulating cost-effective diets with optimum nutrient availability.
