**4.4 Organic animal farming**

Organic farming is a type of animal farming system whose primary aim is to produce high-quality food without the use of synthetic chemicals, that is, chemical fertilizers or pesticides, etc. Additionally, animals are grown in open spaces and fed on natural resources [34].

Livestock represents all animal types like buffaloes, cattle, goats, sheep, horses, and pigs, etc. and they are reared primarily for milk, meat, and wool production. Livestock farming is associated with the production of eggs, milk, and meat from domesticated animals [35].

The basic purpose of these farming systems is the production of agricultural products such as cereal, crops, rice, sheep, fish, and fowl. These all-farming systems are dependent on plants as their primary food source, which in turn, rely on the soil. Merely, the production of farming is influenced by the type of farming system and agricultural action chosen. **Figure 1** [36] depicts the typological classification of the farming system.
