This study was investigate the effect of untreated or biological treated with fungus (Trichoderma reesie) watermelon vine as a replace of berseem hay in ration of lactating goats on their performance and rumen fermentation. Twenty-five lactating goats 2-4 years old were assigned randomly to five groups (five goats in each) using a randomized complete block design. Animals fed ration contained BH plus CFM (1:1) and served as control R1, while groups R2, R3, R4 and R5 fed two levels of sun-dry watermelon vine (WMVH) or biological treated watermelon vine with fungus Trichoderma reesie (WMVF) (25 and 50 %), respectively by replacing BH in the ration. Results showed the goats fed R1 and R4 had significant (P<0.05) improved have been observed in milk production milk fat, protein yield, fat corrected milk (FCM) and feed conversion compared with R2, R3 and R5. The animals fed R1 and R4 were significantly (P<0.05) higher in NH3-N, TVFA's concentrations and propionate than compared the other experimental ration. The animals fed R1, R4 and R5 had significantly (P<0.05) lower values for CO2 and CH4 than R2 and R3. So, it could be recommended that safety introduced of watermelon vine after treating it with fungus in diets without any adverse effect on their performance.
