ÖZETBu çalışmada üreli ve ürezsiz yemlerle beslenen iki tosundanalman rumen iizsuyu numuneleri anaerobik şartlarda inkübasyonatabi tutularak 0, 6, 12 ve 24 üncü saatlerde üreaze aktivitesiuçucu ya~ asitleri konsantrasyonu total canlı bakteri sayısı ve hidrojeniyon konsantrasyonu yönlerinden incelenmiştir.Her iki rumen özsuyu numunesinde de üreaze aktivitesi ve totalcanlı bakteri sayısı başlangıçta en yüksek olup inkübasyon müddetincedereceli olarak azaldığı, uçucu yağ asitleri konsantrasyonuise yükseldiği mi1şiihade edilmiştir. Rumen özsularınıri hidrojeniyon konsantrasyonunda belirli bir değişiklik olmamıştır. Bütünhallerde total canlı bakteri sayısı ve uçııcu yaif asitleri konsantrasyonu üreliyem ile beslenen hayyanda üresiz yemle beslenenden daha fazlabulunmuştur.SUMMARYSTUDJESON UREASE ACTIVITY OF RUMEN MICROFLORAIn Vitro Changes In Urease Acbvity,Concentrations of Volatile FartyAeİdis and Number of Viable Baeteriaof Rumen LiquorRumen fluid obtained from twopermanently fistulated steers was incubatedanaerobically at O, 6, 12 and24 hour intervals for(l) urease activity,(2) Volatile Fatty Acids (VFA) cocentrations,(3) total number of viablebacteria and meolytic viable bacteriaand (4) hydrogen jan eoncentration.The rations of one animal (I)consisted of eorn-alfalfa hayand thatof the other (II) consisted of anemiched one containing com cobs,alfalfa hay, soybean meal, urea andmineral salts.The urease activity and the numberof the viable bacteria and viableureolytic baeteria of the rumen fluidwere bighest at zero time then graduallydeereased for both animals over a24 hours incubation period whileVFA coneentrations of the mmenluquor increaced over the same period.No difference was observed beıweenthe urease activity of the mmenf1uid fr9m animal i and II. in alı cases,~VFA eoncentrations and number ofviable bacteria and viable ureoloyticbaeteria of the animal II were higherthan that" of animal LNo changes were observed in thepH of the rumen liquor over a 24hour ineubatian period.
