Microbial Activities in Alfalfa and Orchard Grass Ensiled Under Certain Conditions in Experimental Silos

摘要: I t is generally recognized that microorganisms are active in silage and lactic acid bacteria perform a useful role the preservation of forage through production acids (1, 2, 11, 1.t). The obviously on at time ensiling 3), but they present such small numbers (8) their usefulness depends favorable conditions for growth prolonged activity. Control bacterial activity by addition mineral (the A.I.V. method) to arrest development (16) has been only partially successful (6) not recommended some because it economically impractical. Similarly, use various additives as selective inhibitors destructive action opposed advocated investigators, must depend basic studies under conditions. effect carbohydrates forms, molasses milk by-products, flora studied investigators (2, 7, 18). Carbohydrates were found be effective lowering p i silage, opinions differ value making high quality silage. Stone et al. (14) was indicated when sugar content low, believed typical fermentation took place irrespective treatment after 2 days storage lactobacilli predominated. Salisbury (11) capacity greater simple sugars than more complex carbohydrates, occur cereal grains. Investigators who have made detailed ensiled observed rapid changes soon (5, 13, 15) attributed these directly or indirectly presence plant juices adequate moisture. Results recent indicate change begins cut. Wilting legume forages field lower moisture (18) practiced widely silages, advantages this method processes largely unknown. In general, literature indicates there methods enhancing very little fundamental information available practical controlling
