Twelve cows in mid-lactation received 4 dietary treatments of varying levels of ipil-ipil (Leucaena leucocephala) leaf meal (ILM) and dried poultry manure (DPM), the control ration containing neither ILM and/or DPM. Each cow underwent four 24-day feeding periods to rotationally receive the 4 rations in a randomized complete block design (RCBD). The control ration was found to have significantly higher in vitro digestibility than the 3 test rations. No significant differences were observed in nutrient intake, body weight changes and income over feed cost. Likewise, insignificant differences were found on milk production, composition and quality as a result of treatment. The data suggests that DPM and ILM can be used at levels of 10 to 20 percent and 10 to 30 percent of dry matter, respectively, in corn silage-based complete rations for lactating cows having passed peak milk production.
