Abstract:In this study, we investigated the effects of tannin extract of chestnut (Farmatan) obtained from sweet chestnut on alfalfa silage. Alfalfa harvested at the flowering stage was chopped to 1-2 cm in size and laid on a flat surface. Farmatan at the levels of 0 (control group), 1.5, 3.0 and 4.5% was uniformly spread by hand on the silage material. After thoroughly mixing the silage material, it was placed in 1.5-2.0-kg airtight plastic bins and stored for two months. Farmatan had significant effects on the compos… Show more
Usage of high quality forage that enhances the production efficiency in the livestock industry is a quite important issue. During a famine period or when it is unavailable to reach fresh forage due to seasonal factors, the ensiled forage becomes a vital role for feeding ruminants. Lactic Acid Bacteria (LAB) is the most important microorganisms in silage for desired fermentation. In this work, LAB isolation in epiphytic flora from diverse field forage crops and ecologies in Turkey were made in order to determine their fermentative capacity and to develop a high-quality silage inoculant. For this purpose, the forage crops were collected from several rangelands from different altitudes of 39 to 1516 m and isolations were made from both fresh forage and ensiled material. Total acid production capacities of isolates were determined and 70 isolates were selected in terms of acid zone creation in growth media containing CaCO 3. Then, LA production levels in MRS broth media of isolates were determined and final 10 isolates were selected for inoculation trials. Also, morphological, physiologic, biochemical properties of selected 10 isolates were analyzed and identified by the BIOLOG kit on species level. Isolates that have outstanding properties about lactic acid productivity are left to use further inoculation research work.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
