Conventional feedstuffs especially corn, fish meal or soybean meal are lacked of supply and the prices have increased continuously. Therefore, studies finding the unconventional feedstuffs would help to reduce feed cost. Nakhon Ratchasima province is the largest area of cassava production, approximately 45% of the total production is used to produce cassava starch and generated by-product approximately 2-3 tons annually. Since cassava pulp still remains high in starch content, therefore the pulp has widely used as an alternative energy source in animal diets (Khempaka et al., 2009; Khempaka et al., 2014). However, the fresh pulp also contains high moisture content approximately 70-80% which can cause a problem of drying in raining season. The combination of fresh cassava pulp and dried Napier Pakchong grass may help to resolve this problem. Napier Pakchong grass is fast-growing grass and wildly produced in Nakhon Ratchasima area. This grass yield 70-80 tons/rai/year and contains 10-12% protein on DM basis. Therefore, the objective of this study was to evaluate the effects of mixed cassava pulp and Napier Packhong grass on nutrient digestibility and retention in laying hens.
