*2.2. Animals and Experimental Design*

Five crossbreed Thai Native–Anglo-Nubian goats (50%) at 9 to 12 months of age and 20 ± 1 of body weight (BW) were used in this study. All goats were injected with ivermectin (IDECTIN® The British Dispensary (L.P.) CO., Ltd., Bangkok, Thailand) with 1 mL dose per 50 kg of BW to kill parasites before starting the experiment. Goats were assigned to a 5 × 5 Latin square design. Treatments were fermented discarded durian peel without additives (FDP), fermented discarded durian peel with 5% of molasses (FDPM), fermented discarded durian peel with 2% of cellulase (FDPC), fermented discarded durian peel with 1.0 <sup>×</sup> <sup>10</sup><sup>5</sup> cfu/g fresh matter of *L. casei* TH14 (FDPL), and fermented discarded durian peel with 5% of molasses, and 1.0 <sup>×</sup> <sup>10</sup><sup>5</sup> cfu/g fresh matter of *L. casei* TH14 (FDPML).
