The experiment was conducted to evaluate physical quality of meat in broiler fed diets with addition of tapioca by-product and tofu waste fermented with a combination Aspergillus niger and Rhizopus oligosporus as a substitution for corn. Two hundred DOC’s unsex Lohmann Platinum strain were randomly divided into 25 groups containing eight birds each. Experiment was designed by using “Completely Randomized Design” with five treatments, replicated five times. The treatments of feed used were P0 = basal diet + corn P1 = basal diet + Corn subtituted 5% OAF, P2 = basal diet + Corn subtituted 10% OAF, P3 = basal diet + Corn subtituted 15% OAF, P4 = basal diet + Corn subtituted 20% OAF. Chickens were raised for 35 days. Drinking water and feed were given ad libitum. Meat samples (Pectoralis superficialis) were taken to determine the physical qualities of meat. The results showed that addition of OAF did not exertisignificant effect on carcass presentage, pH, water-holding capacity, and cooking loss of meat of broiler. The conclusion was that the additional of OAF cannot improve the quality of physical broiler meat. The best result showed at third treatment with 15% OAF substitution of feed.

Lovebird is a type of bird that many people have as a pet or for a competition. This bird needs adequate nutrients for survival. In reality, there are many of them that over or low nutrients. This study will discuss about how to optimized the composition feeds of lovebird and minimize the costs without reducing the nutrition. Particle Swarm Optimization (PSO) is one of the optimization methods that used for the formulation process and the composition to keep fulfilling the nutrient needs with minimal cost. The PSO algorithm process starts with the initialization process for position, velocity, pBest values as much as the particles and gBest. Then proceed to update the velocity, position, pBest and gBest as much as the iteration that has been determined. Based on the results of the test that have been done in this study, the writer obtains the optimal parameters such as the number of particles as much as 60, the number of iterations is 600 and the value of coefficient k is 0.3. By using these parameters, the price difference is Rp 5,540.00.

The experiment was conducted to evaluate the production performance and egg quality of laying hens supplemented with phytobiotics and magnetized drinking water. This experiment used 2700 gauss level in Magnetized Drinking Water (MDW). The phytobiotics had two form: the non-encapsulated phytobiotics (PTO) and encapsulated phytobiotics (EPTO). There were untreated water (control) and the treated water (MDW, PTO, PTO+MDW, EPTO, EPTO+MDW). The treatments were presented by 0.6% for each treatment. The result showed highly significant (p<0.01) improvement on feed conversion ratio (FCR) but no significant effect on other production performance variables including feed intake, hen day production (HDP), egg mass, and income over feed cost (IOFC). The results indicated a highly significant improvement (p<0.01) on egg weight and yolk cholesterol. There were no significant effects on shape index (SI), shell weight, shell thickness, Haugh unit (HU), albumen height, yolk weight, yolk index (YI), and yolk color of egg quality variables. It was concluded that the encapsulated form (EPTO and EPTO+MDW) had the best improvement on FCR and yolk cholesterol, on another hand the non-encapsulated form (PTO and PTO+MDW) increased the egg weight of laying hens
