**7.3 Comparison between intensive and extensive animal farming**

The animal feeding pattern and milk production system were compared in a study carried out in Sri Lanka where the author concluded that animals reared in the intensive farming system had highest herd size (3.7 animal unit) with better feeding level when compared with extensive farming system (2.7 animal unit). The average milk production under extensive systems was significantly lower (P < 0.01) at 3.9 animal units per day compared to 5.41 animal units per day under the intensive farming system. Livestock farming is an important source of income for peoples of Sri

Lanka and dairying under an intensive farming system is proven more profitable than an extensive farming system [47].

In Bangladesh, performance traits of buffalo selected randomly from 14 farms under both intensive and extensive systems were evaluated and it was found that dry milk yield and live weight were considerably higher in the intensive farming system. Reproductive traits were moderately higher under the intensive farming system. Intensive farming system is currently under application in Bangladesh for better milk production [48].
