Citrus pulp is an important by-product for sub-tropical and tropical ruminant animal production. In this study two wethers (38 ± 1.5) were used insitu method. Wetheres equipped with ruminal cannulas. Ruminal DM and CP disappearances were measured 0, 4, 8, 12, 24, 36, 48, 72 and 96h. The gas production was measured at 2,4,6,8,12, 24,36 and 48 h. Dry matter degradabilities of Orange, Grape fruit, Lemon and Tangerine at 96h were 92.1, 94.3, 86.3 and 92.1 respectively. Crude protein degradabilities of mentioned citrus pulps were 40.0, 37.1, 31.0 and 35.9 respectively. DM and CP in situ degradability at 96h showed significant differences (P < 0.05). Orange pulp showed high level of metabolizable protein (73.97 %) there were significant differences (P < 0.05). the most rate of gas production is related to grapefruit pulp showed significant differences (P < 0.05). data showed that citrus pulp can be used as a high energy feed in ruminant rations to support growth and lactation, with fewer negative effects on rumen fermentation than starch rich feeds.
