A six-month feeding trial was conducted on eight lactating Murrah Buffalo cows to determine the effects of incorporating dried poultry manure (DPM) in their diet on their milk production and performance. The treatment rations were: T1 - feeding of standard concentrate mixture (control) and T2 - feeding of standard concentrate mixture substituted with 30% DPM. While the animals receiving T2 gained weight, those on T1 lost weight. The difference in changes in body weight was significant. Average daily milk yield, 4% FCM production and concentrate intake were significantly lower (P0.05) with T2 compared to T1. No significant differences were found in terms of butterfat, total solid, solid-non-fat, moisture content, specific gravity and acidity. Milk protein was significantly higher with T2 compared with T1 (P0.05). Off flavor was detected from the milk of T2 animals, the unpleasant flavor however, could be corrected by pasteurization. Income over feed cost was higher in T1 (P32.91) than T2 (P24.68). It is thus uneconomical to incorporate 30% DPM in concentrate ration for dairy buffaloes. Results obtained from this study indicated that the replacement of 30 percent DPM in the concentration ration of lactating cows did not significantly affect milk yield, composition and performance of the animals except in the milk protein which is significant. It was found likewise to be uneconomical.
