This study aimed to determine the effect of feeding mash or pelletized sugarcane bagasse based diet to growing crossbred Boer male goats (Boer X Damascus) on feed intake, growth performance, nutrients digestibility, some rumen parameters, serum parameters and the economic outcome. Twenty of growing crossbred Boer goats (averaged 7 months of age and weighted 19.72 ±0.87 kg) were divided into two equal groups (10 animals each), the first group received mash form bagasse while the second group received pelleted form bagasse diet. The results showed that pelleted group diet was significantly (P< 0.005) higher in nutrients digestibility, and dry matter intake compared to the other group. Ruminal ammonia nitrogen (NH₃-N), TVFA and total nitrogen were increased (P<0.05) for goats fed pelted form diet compared with this fed the mash form diet. Average daily gain, total weight gain and feed conversion were significantly higher (P<0.05) for goat's consumption diet in pelleted form compared with mash form diet. Dry matter intake, TDNI, CPI were significantly higher (P<0.05) in pelleted form group compared with mash group diet. Serum concentrations of total protein, albumin, globulin, cholesterol, GOT, GPT and urea were higher (P<0.05) for group fed pelleted diet compared with another group. The results indicated that using sugarcane bagasse in pelleted form in growing crossbred Boer goats improved nutritional digestion, growth performance and reduced feed costs without any negative effect on performance
