Enzyme addition improved the silage's nutritive value by increasing in vitro organic matter digestibility (OMD), in vitro gas production at 48 h (GP_(48)) and in sacco degradation of DM at 48 h incubation (DMD_(48)), and the DMD_(48) in group 2 was the highest and 15.4% higher than that in the control (P<0.01).
It suggested that all the additives can improve the quality of alfalfa silage, and the treatments of FA+G (5.5ml/kg FA+1.0g/kg G) and PFJ+FA(2.5ml/kg PFJ+5.5 ml/kg FA, 5.0 ml/kg PFJ+5.5 ml/kg)had better effect on improving silage quality than other treatments.
long life span, early turn green in spring, resistance to cold, salt and alkaline, the plant height is 2￣2.5 m in the blooming stage, the grass fresh yield is 150￣200 t. hm -2 is 29.8%￣39.81%,and the hay and ensilage can be eaten by each livestock and poultry. It is the best ensilage cop for pigs and cattle, especially cow.
Some sensory assessments,such as colour,aroma ,taste and texture tests should be included inthe quality identification for ensilage beside pH value,and laboratory analysis on lactic acid,butyric acidand total acidity.
Two pure cultures of obligate methanotrophs, strains H-11 and O-12, growing in the temperature range from 30 to 61°C with a optimum at 55°C were isolated from samples of silage and manure.
A simple HPLC column-switching technique for the determination of deoxynivalenol (vomitoxin) in maize and corn silage
A method is described for the determination of deoxynivalenol (DON) in maize and corn silage with a detection limit by UV of 0.2 ppm after a simple separation by means of connected reversed-phase columns.
HPLC determination of catabolic amines in silage using their dansyl derivatives and an electrochemical detector
A chromatographic profile of amines from the proteolytic catabolism of maize silage byClostridia is shown.
