  The present study investigated the relationship between addition of a commercial organic acid mixture to feed and feed microbiology. Feedstuffs′ composition and duration, temperature and humidity of feed storage were taken into account. The evaluated organic mixture contained formic acid, ammonium formate, propionic acid, ammonium propionate and inorganic phyllosilicate carrier. Microbiological changes were investigated in five types of feed using a 2x2x2 factorial design: organic acid addition (with/without), conditions of storage (22°C and 57% relative humidity (HR)/41°C and 65% HR) and storage duration (30/60 days). Supplementation of the organic acid mixture has positive effect on feed microbiology.

  The purpose of the current work was to extend the study of the effect of temperature on silage microbiology, with or without formic acid, and on the aerobic stability of corn and vetch-grain silages.
The silage samples were ensiled in 1.0-l anaerobic jars, with and without formic acid, at room (20°C) or elevated temperatures (30-37°C). After 45 days of ensiling, the silages were subjected to an aerobic stability test at room (20°C) and elevated (30-37°C) temperatures. The most intensive deterioration occurred at 30-37°C. Samples incubated at 30-37°C had the highest yeast and mould count, most prolific CO2 production.
The finding of the current study suggests that formic acid may decrease mould growth in silage samples. Unfortunately, formic acid does not reduce aerobic deterioration rate of silages. Applying a 5 g/kg formic acid on corn and vetch-grain silages was not very effective at high temperatures.

  Around the problems and success during the spreading of the innovations of the agricultural office of the province Tekirdag to determine 89 agricultural engineers of the agricultural office be came Tekirdag and 153 farmers to who cultivation of maize silage was taught asks. In the case of this investigation the succes of the advisors affecting factors be came like as well as professional experience, satisfaction, commucation with other advisory resembles conferences with teaching the agriultural tecniques until the futuring of the maize silage farmers like acknowledgment and preparation to maize silage animal and resembles mixtures, futuring for each kind that seized.
