Abstract


DIGESTIBILITY OF DRY MATTER, NITROGEN RETENTION AND METABOLIC ENERGY IN RATION OF BROILERS USING YELLOW PUMPKIN MEAL (Cucurbita moschata). Research was conducted to evaluate digestibility of dry matter, nitrogen retention and metabolic energy corrected to nitrogen in ration of broilers using yellow pumpkin meal (Cucurbita moschata). The total of 20 unsexed broilers of CP 707 strain at age of 5 weeks old with the average body weight of 1073 grams were used in this study. The completely randomized design involving 4 treatments and 5 replications in each treatment was applied at the experimental unit. The significant treatments were tested using honestly significant difference test. The treatments were including 100% basal ration without yellow pumpkin meal (R0), 95% basal ration added with 5% yellow pumpkin meal (R1), 90% basal ration added with 10% yellow pumpkin meal (R2), and 85% basal ration added with 15% yellow pumpkin meal (R3). Results of analysis of variance showed that treatments significantly affected (P<0,05) nitrogen retention value, but did not significantly affected (P>0,05) dry matter digestibility and metabolic energy corrected to nitrogen in ration. Based on honestly significant difference test, treatments of R0, R1 and R2 were higher compared with R3. Among treatments of R0, R1 and R2 were not significantly different. Therefore, it can be concluded that yellow pumpkin meal (Cucurbita moschata) was potential to be the alternative material ingredient up to 15 percents in ration of broilers based on digestibility of dry matter, nitrogen retention and metabolic energy.

 Key Words: Broiler, Dry matter, Metabolic energy, Nitrogen retention, Yellow pumpkin meal.
