The crude protein content and nitrogen free extract content of the regrowth of treatment Ⅱ were higher,while the crude ashes content and acid detergent fiber content were reverse.
However,alfalfa silage sprayed with previously fermented juice contained higher content of acid-detergent fiber,30.21%,while that of the control was only 28.83%(P<0.05).
6.39%, 37.04%, 163.33mg/kg, respectively. In the whole year, theAugust contents of crude protein and fluorine were the highest withADF, NDF the lowest.
An enzyme was added to fresh corn stover at four levels, 0, 500, 750, 1 000 mL/t corn stover (dry matter basis,DM) and silages were prepared All the silages were of high quality by evaluation of subjective criteria Addition of enzyme decreased contents of neutral detergent fibre (NDF) and acid detergent fibre (ADF) The highest level of enzyme addition decreased the contents of NDF and ADF by 7 0% and 4 8% ( p <0 05), compared to the control Lactic acid contents were 132 9, 122 5, 129 9, 1...
The characteristics of growth and quality of hybrid progenies of L.multiflorum and F.arundinacea was compared. The results showed that the plant height, dry matter yield and crude protein content of both progenies F 2-4S-8 and F 2-2-1 were higher, but the content both acid detergent fiber and neutral detergent fiber were lower than parent Kentucky 31.
The study of production characters and quality under light grazing (LG),medium grazing (MG),heavy grazing (HG)and no grazing(CK)was carried out on a russian wildrye grass( Psathyrostachys juncea (Fishch)Nevski)pasture during growing season(mid June to mid September)in 1997.The results showed that plant height declined with increasing of the grazing intensity,while the tiller quantities increased;the more of the tiller number,the less of the tiller weight in russian wildrye grass under grazing.The order ...
