Extract

Dried citrus pulp (DCP) as a by-product from juice extraction of citrus fruit can be used as a feedstuff for ruminant animals (Belbaskis and Tsirgogianni, 1996). The DCP is composed of peel, inside portions, and culled fruits of the citrus family (e.g., orange, lemons, and grapefruit). The DCP is a pectin-rich bulky concentrate that is rich source of energy, fibre and calcium, but poor in CP and phosphorous. There is a different of opinion among researchers about the effect of DCP on milk yield, milk composition and blood metabolites components. The main objective of this experiment was to evaluated effects replacement of dried citrus pulp with barley grain on milk yield, milk composition and blood metabolites of dairy cows.
