Resumo: The effects of fat sources on intake, nutrient digestibility and plasma urea nitrogen were evaluated in lactating water buffalo. Twelve females were randomly distributed into four treatments: without additional lipid, soybean grain, soybean oil and cottonseed. The experimental period was 84 days, with four 21-day periods (14 days for diet adaptation and 7 for collection). Diets were offered ad libitum, twice daily, as total mixed ration. At the collecting period, samples of food and surpluses were weighed and collected for chemical analysis. Faeces samples were collected from rectum for estimation of faecal dry matter production, using indigestible neutral detergent fiber as indicator, and consequently for apparent digestibility calculations. Dry matter (DM), crude protein (CP), neutral detergent fiber (NDF) and acid detergent fiber (ADF) intakes were similar between treatments. The ether extract intake was higher for soybean oil diet. The same behavior was observed for the total digestible nutrient (TDN) intake for this diet, since the previous diet showed higher TDN percentage. The digestibility coefficient for DM, CP, non-fibrous carbohydrate, and serum urea nitrogen were similar between diets. Different lipid sources in the diets for lactating water buffalo did not influence the DM intake and digestibility coefficient, when ether extract content was under 5%. However, the ether extract and fibrous fractions digestibility coefficients in diets with soybean grain and cottonseed were the lowest.
