This study aims to determine the effect of the use of various liquid probiotics in drinking water on the quality of the reproductive tract and quail production. The study uses a Completely Randomized Design with directional pattern with four treatments, namely: quail gets drinking water without liquid probiotics (P0), quail gets drinking water with commercial probiotics A (P1), quail gets drinking water with commercial probiotics B (P2), and quail gets drinking drinking water with commercial probiotics C (P3), 5 replications and 5 quails in each study unit. Drinking water is given ad libitum with a liquid probiotic concentration of 2ml / liter. Quail feed contains 22.2% PK and 3032.5 kcal energy. The treatment affected the weight of the reproductive tract + eggs, egg weight and length of the reproductive tract, weight before slaughtered, weight after slaughtered, weight after hair removal, heart weight, gastrointestinal weight, (P <0.01) but had no effect on carcass weight, liver weight, follicular weight, gizard weight, digestive tract length and caeca length. The treatment of liquid probiotics in drinking water increases several indicators of quail reproduction and production.

The research was aimed to evaluate the effect of biogas liquid waste as a fermentation starter of rice husk to the nutrient content, gross energy and bulk density. The method used laboratory experiment using a completely randomized design (CRD) on factorial pattern (6 x 5) with the level of biogas waste liquid : P0-treatment (0% negative control), P0+ (Cellulomonas sp as positive control), P1 (5%), P2 (10%), P3 (15%), P4 (20%) ml/g, and the incubation time : T0 (0 day control ), T1(7 days), T2 (14 days), T3 (21 days) and T4 (28 days). The variables measured was the content of ash, crude protein, crude fiber, crude fat, gross energy and bulk density. Data were analyzed by analysis of variance (anova) CRD Factorial pattern and if there is a significant difference was followed by Duncan's Multiple Range Test. The results of research was the level of biogas liquid waste and the incubation time provides a significant influence (P<0.01) on the nutrient content, gross energy and bulk density of rice husk. The interaction level liquid waste provision of biogas and incubation time was highly significant (P<0.01) on the nutrient content, gross energy and bulk density. It can be concluded that the addition of biogas liquid waste 15% (ml/g) with a time of incubation for 21 days have best rice husk quality content based on improvement of crude protein, crude fat, and gross energy with lowest crude fiber.

This research aimed to compare the characteristics of free-range eggs consumers, to analyse their buying decision process and consumer satisfaction level, and to formulate the implication on free-range marketing mix across wholesalers and retailers in Purworejo districts. The research sample was 32 respondents, consisted of 16 wholesalers and 16 retailers selected with purposive sampling because of the limited number of respondents in each sub-district. The consumers were selected through snowball sampling from one respondent to another. The parameters included the general characteristics, the decision to buy free-range eggs, consumers’ satisfaction level, and marketing mix implications. The Data were analysed descriptively using Chi-Square, Mann-Whitney Customer Satisfaction Index (CSI), and Importance and Performance Analysis (IPA). The result found different characteristics across consumers of free-range eggs in both wholesalers and retailers regarding age group, marital status, education background, gender, occupation, and geographic locations. The different process of buying decision making was due to need identification. Regarding gathering information, the wholesaler consumers relied on electronic media and their neighbours, whereas the retailer consumers only from their neighbours. The main consideration to purchase free-range eggs among wholesaler consumers was the cleanliness of eggs, whereas the retailer consumers were the cleanliness and price of eggs. The consumer satisfaction index on consumers in wholesalers and retailers was 65.16 and 68.82, respectively, indicative of the satisfied category. The marketing mix implication on both sellers was improving the cleanliness of free-range eggs and the market area, matching selling price with the market price, controlling the quality of free-range eggs from the suppliers, and revisiting the supply system to ensure the real-time availability of free-range eggs.

Poultry is susceptible to mycotoxicoses caused by aflatoxins. Two experiments were carried out, where twenty-four, 28days old and 144 one-day-old broilers were assigned to six diets respectively. The diets were: diet1 (no aflatoxin and not fermented), diet2 (no aflatoxin and fermented without yeast), diet3 (no aflatoxin and fermented with yeast), diet4 (contained aflatoxin and not fermented), diet5 (contained aflatoxin and fermented without yeast) and diet6 (contained aflatoxin fermented with yeast). The aflatoxins were 20.034 and 30.08ppb for the first and second experiments respectively. In the first experiment, each diet was assigned to 4 chickens for 7days adaptation and 7days for feces and leftover collection. The feces were oven dried for the determination of dry matter digestibility (DMD), metabolizable energy (ME) and nitrogen (MN). In the second experiment, each diet was assigned to six chicks, replicated 4 times for 21days. Leftovers and mortalities were recorded daily and chicks were weighed on a weekly basis. The results showed that DMD and MN were significantly (p<0.05) affected by fermentation. Natural fermentation improved DMD of the clean and contaminated diets. No difference found in feed intake and body weight gain. However, gain: feed ratio was significantly (p=0.048) better in broilers fed diets fermented naturally. The mortality rate was 75.0% in chicks fed on aflatoxin diet which was not fermented. Therefore, natural fermentation is the best method of improving the quality of aflatoxin contaminated feed for broilers.
