EVALUATION OF BIOLOGICAL VALUE OF COMPLETE FEED BASED ON CORN COB AND MIXED GRASS ON PRODUCTION PERFORMANCE OF ONGOLE. This study was aimed to obtain the feed formula, which is effective on the productivity of beef cattle (PO). This study consisted of two experimental stages, namely: 1). In vitro experiment, and 2). Biological (in vivo) experiment. t-test two sample assuming unequal variance was used as the statistical analysis on both experiments. The treatments of this research consisted of RA feed = 50% concentrate + 50% corn forage and RB feed = 50% concentrate + 50% mixed grass, and it was repeated 10 times. In vitro test was used to measure dry matter and organic matter digestibility and NH3 concentration (NH3). The biological experiment (in vivo) was used 20 PO cattles, 12-18 months of ages, with 120 - 180 kg of body weight to measure feed intake, nutrients digestibility DMD, OMD, Protein and energy digestibility, live weight gain (LWG) and feed conversion (FCR). The results showed DMD and OMD in vitro of RA were 67.88% dan 66.06%, respectively, lower than the DMD and OMD obtained in RB, i.e 71.15% dan 69.08%, respectively. Meanwhile, NH3 of RA was higher than RB, i.e: 3.20 vs 2.50 mM/L. The biological experiment showed the DMD, OMD, CPD, and DE (in vivo) of RA were 77.05%, 78.64%, 82.13%, and 83.48%, respectively, while the results obtained at RB were higher, i.e. 80.15%, 83.44%, 85.55%, and 87.46%, respectively. On the liveweight gain (LWG) of PO cattle, the RA ration produces 0.60 kg per head per day, lower than RB which produces 0.65 kg per head per day. The FCR of both ration was 0.11. It is concluded, complete feed based on forage corn and mixed grass can be used as standard feed for fattening of local beef cattle because it is able to give high nutrient digestibility and good feed conversion valueÂ Keywords: Complete feed, in vitro and in vivo digestibility, liveweight gain, feed conversion

EFFECT OF SUBSTITUTION OF FISH MEAL WITH MAGGOT (Hermetia Illucens) MEAL ON CALCIUM (Ca) AND PHOSPHORUS (P) DIGESTIBILITY OF BROILER CHICKEN. As an animal feed, maggot from black soldier fly (Hermetia Illucens) has high calcium (Ca) Â and phosphorus (P) content. Yet, little is known about the digestibility of calcium (Ca) and phosphorus (P) in the diet containing maggot. The present study was designed to determine the effect of substitution of fish meal with maggot (Hermetia illucens) meal in the diets on (Ca) and phosphorus (P) digestibility of broiler chicken. Twenty day old chicks (DOC) CP 707 broiler chicken of about 1300-1500 g body weight were assigned to each dietary treatment which was replicated four times in a Completely Randomized Design (CRD) arrangment. The experimental diet consisted of 5 treatments and 4 replications, formulated as follow: R0 = 100% fish mealÂ + 0% maggot meal; R1 = 75% fish meal + 25% maggot meal; R2 = 50% fish meal + 50% maggot meal; R3 = 25% fish meal + 75% maggot meal; and R4 = 0% fish meal + 100% maggot meal. Calcium (Ca) and phosphorus (P) digestibility were calculated using total collection method. Parameters measured were calcium (Ca) and phosphorus (P) digestibility. Differences were considered significant at P < 0.05. Tukey test (HSD) was employed to further analyze among treatment diferences. The results showed that calcium (Ca) digestibility was significantly (P < 0,05) increased as the level of maggot (Hermetia Illucens) meal in the diets increased; whereas the digestibility of phosphorus (P) was not significantly (P > 0,05) affected by the treatments. It can be concluded utilization of maggot (Hermetia illucens) meal up to 100% replaced fish meal or Â 15% in the diet, inreased calcium (Ca) digestibility and did not affect phosphorus (P) digestibility of broiler chicken. Â Key words: Fish meal, Maggot (Hermetia Illucens) meal, Calcium and Phosphours digestibility
