| Summary: | This study was conducted to determine the best level of noni fruit extract (Morinda citrifolia L) addition into citrate-yolk extender on the motility of boer goats spermatozoa preserved at 5℃. Semen was collected using artificial vagina once a week from 1 healthy male aged ±7 years,. The treatments were citrateyolk administrated by noni fruit extracts (P0: 0 g, P1: 2 g/100 ml, P2: 4 g/100 ml, P3: 6 g/100 ml, P4: 8 g/100 ml) and stored at 5℃. The parameters were motility spermatozoa percentage. Observations were made at 2, 24, 48, 72 96 hours after refrigeration. The data obtained was analyzed with split plot analysis of variance (ANOVA) follo wed by Duncan test. The average percentage of sperm motility after refrigated for 96 hours in the groups P0; P1; P2; P3; and P4 respectively was 24,20±0,83%; 34,40±4,61%; 40,20±5,71%; 14,64±21,63%; and 9,54±21,33%. The results showed that giving of noni fruit extract significantly affected (p<0,05) on the percentage of motility spermatozoa of boer goat after refrigeration. It was concluded that the administration of 4 g/100 ml noni fruit extract in citrateyolk after stored at 5℃ resulted a greater sperm motility for up to 96 hours.
