The aim of the experiment was to find out the effects of steaming sago (Metroxylon Spp) and golden snail meal (Pomacea Spp) combination for yellow corn substitution, on the performance of male Alabio, Mojosari, and their cross(MA). One hundred and ninety two young male ducks from the three breeds of 7 day old were assigned in 48 units of pens (4 ducks/pen). The experimental design was Completely Randomized Design with factorial (3x4) the first factorwas duck breeds (a) consisted of three duck breeds, Alabio, Mojosari, and Raja ducks, and the second factor was the type of ration of: R0 (control/100% basal ration), R1 (basal ration + 13% steaming sago and 2% golden snail flour), R2(basal ration + 26% steaming sago and 4% golden snail flour) and R3 (basal ration + 39% steaming sago and 6% golden snail flour). All treatments were repeated four times. The observed variables were the performance of ducks(body weight, body weight gain, ration consumption, and feed conversion ratio). The results indicated that breed had significant effects (P<0.05) on body weight, body weight gain, and ration conversion. Meanwhile, types of feed hadsignificant effects (P<0.05) on feed consumption, body weight gain, and final body weight. It was concluded that the combination of steaming sago and golden snail meal up to 45% of the ration could replace the need for yellow corn assource of energy without affecting the performance of male ducks of 1–8 weeks old. Cross male ducks were better than male Alabio and Mojosari ducks because they were more efficient in converting ration in to meat which resulting inhigher body weight gain.(Key words: Steaming sago, Golden snail flour, Male ducks, Performance)

The research was conducted to analyze the effect of seaweed Gracilaria edulis in the diets on the performance of pullet. One hundred and twenty six Lohmann Brown Strain pullets of 14 weeks old were divided into seven seaweed diet treatments. The treatment diets were R0, R1, R2, R3, R4, R5, and R6 contentaining 0.00; 2.50; 5.00; 7.50; 10.00; 12.50 and 15.00 of seaweed, there was three replications, six pullets of each. The collected data were feed consumption, weights and ages of sexual maturity, feed conversion ratio, weight of egg and Iodine content in the egg. The collected data were analyzed by analysis of variance of one way classification, followed by Duncan’s New Multiple Range Test (DMRT). The results showed that the treatments had not significant differences on feed consumption, body weight at sexual matuarity, feed conversion ratio, but significans (P<0.05) on ages at sexual matuarity and egg yolk color (P<0.01). Feed consumption were 80.94 g/chicken/day; 81.02 g/chicken/day; 80.95 g/chicken/day; 81.43 g/chicken/day; 81.69 g/chicken/day; 82.25 g/chicken/day and 82.72 g/chicken/day, body weight at sexual matuarity1898.56 g; 1977.78 g; 1947.78 g; 1947.78 g; 1949.78 g; 1981.67 g; 1949.44 g, FCR 5.78; 5.35; 5.45; 5.08; 5.57; 5.86 and 6.25, egg yolk color 10.23; 11.27; 11. 83; 12.11; 12.44; 12.44 and 12.83 for R0, R1, R2, R3, R4, R5, and R6 respectively. Egg weights were 51.25 g; 54.50 g; 50.89 g; 51.66 g; 51.36 g; 51.36 g and 50.83 g, for R0, R1, R2, R3, R4, R5, and R6 repectively. There had not significant differences on content of egg yolk iodine were 0.47 ppm; 0.48ppm; 0.50 ppm; 0.52 ppm; 0.55 ppm; 0.56 ppm and 0.60 ppm. It was concluded that the use of seaweed Gracilaria edulis until 15.00% in the diet did not decrease the performance of pullet phase and increased egg yolk color, also did not increase iodine in the yolk.(Key words: Seaweed Gracilaria edulis, Diets, Chicken’s work, Pullet phase)

his research aims to determine the physical characteristics and quality of eggs of mountain Maleo bird (Aepypodius arfakianus) in Papua and to determine hatching rate by using some modified hatching method to improvethe egg’s hatchability. This research used observation method to analyze variable egg hatching, temperature and humidity. There were three experiments of hatching method, which were semi-natural hatching outside of the habitat(ex-situ), hatching by using soil and serasah as the media, and hatching by using electric shelves as the media. Observation data of natural hatching showed that the temperature inside of the nest was about 30-35oC with humidityof 70-90%. The variables measured were embryo durability or fertility, hatchability, period of incubation, hatch weight, and embryo mortality. The data were analyzed using descriptive statistics and correlations for some data required and was presented as mean values and standard deviation (SD). Hatching using electric shelves as the media showed the best result. Length of incubation, egg fertility, hatchability, embryo mortality and hatch weight were 40.14±0.69 days,90.00%, 77.78%, 22.22%, 112.94±7.84 g, respectively; those of ex-situ modification were 47.50±0.71 days, 80%, 25%, 75%, 109.05±2.33 g, respectively; and those of soil and serasah media were 41.33±0.58 days, 90%, 33.33%, 66.67%, 113.33±5.05 g, respectively. Hatching modifications using electric shelves improves the quality of hatching, shorten theperiod of incubation, and reduced the mortality.(Keywords: Mountain Maleo (Aepypodius arfakianus), Hatching modification, Hatchability)
