Bu araştırma, bir homofermantatif laktik asit bakteri (LAB) inokulantının ve formik asit temeline dayalı bir koruyucunun (FAT) düşük kuru maddeli (KM) küçük balya mısır (Zea mays L.) silajının aerobik stabilite ve yem değeri üzerine olan etkisinin belirlenmesi amacı ile yürütülmüştür. Mısır süt olum döneminde hasat edilmiş (%26,4 KM) ve yaklaşık 2,0 cm boyutunda parçalanmıştır. Araştırmada LAB inokulantı olarak Pioneer 1132 H/M F, FAT olarak KemiSile 2000 adlı ticari ürünler kullanılmıştır. Katkı maddeleri mısıra sırasıyla, LAB 106 cfu/g; FAT 3, 4 ve 5 g/kg; LAB+FAT 106 cfu/g+3 g/kg, 106 cfu/g+4 g/kg, 106 cfu/g+5 g/kg düzeyinde katılmıştır. Kontrol ve katkı maddeleri ile muamele edilen mısır her uygulama için 3’er tekerrür olmak üzere 30 kg kapasiteli plastik torbalara silolanmıştır. Silolamadan 60 gün sonra açılan silajlarda kimyasal ve mikrobiyolojik analizler yapılmış, silajlara 5 gün süre ile aerobik stabilite testi uygulanmış ve ayrıca silajların in vitro organik madde (OM) sindirilebilirlikleri ve metabolik enerji (ME) değerleri saptanmıştır. Sonuç olarak, homofermantatif LAB inokulantı, FAT ve LAB+FAT kombinasyonu düşük KM’ li mısır silajlarının aerobik stabilitelerini etkilemezken, in vitro OM sindirilebilirliklerini ve ME değerlerini düşürmüştür.

Oregano, which grows widely in the temperate regions of Europe, Asia and North Africa, has been known as a medicinal plant since ancient times. Thyme used in the spice industry and in the pharmaceutical industry due to its anti-fungal and antiseptic properties because it has an aromatic smell, also contains some vitamins and minerals that humans and animals need. The use of oregano, which comes to the forefront in the feeding of small ruminants during the times when animal feeds are scarce in our country, is becoming more and more important in small head and poultry production and good agriculture and organic farming applications due to some secondary metabolites it contains.

This study was carried out to determine the effects of lactic acid bacteria (LAB) inoculants and lactic acid bacteria+enzymes (LAB+E) inoculant on the fermentation, aerobic stability, and feed value of rye silages. Whole crop rye was harvested at dough stage. Biosil (Wuthenow, Germany), Silaprilis Pro (Timac Agro, USA) and Sil-All (Allteck, UK) were used as lactic acid bacteria and lactic acid bacteria+enzyme mixture inoculants. Inoculants were applied to silages at 6.00 log10 cfu/g levels. After the treatment, alfalfa was ensiled in 1.0-L special polyethylene vacuum bags. The bags were stored at 20±2°C under the laboratory conditions. Three bags from each group were sampled for chemical and microbiological analyses 2, 4, 8 and 75th days after ensiling. At the end of the ensiling period, all silages were subjected to an aerobic stability test for 5 days. In addition, in vitro dry matter, and organic matter digestibility of experiment silages were determined. The results showed that lactic acid bacteria and lactic acid bacteria+enzyme mixture inoculants increased characteristics of fermentation and aerobic stability of rye silages. Lactic acid bacteria+enzyme mixture inoculants decreased neutral detergent fiber, acid detergent fiber and celluloses content in the silages. Lactic acid bacteria+enzyme mixture inoculants increased in vitro dry matter digestibility, organic matter digestibility and metaboze energy of rye silages. Therefore, lactic acid bacteria and lactic acid bacteria+enzyme mixture inoculants might improve the fermentation properties and feed values of rye silages harvested at dough stage.
