Effects Of Solid Ferment Technological Parameter On Ferment Quality Of Rapeseed Meal

Growing pigs were used to study the effect of environmental protection feed and production technology by four processing experiments.The first experiment was conducted to study effects of essential amino acid supplementation of low protein diet on the performance and nitrogen output in fecal. 300 growing pigs(Duroc×Landrace×Large white) were divided randomly into control and four trial group by sex and weight.Each group had three repeat with twenty piglets. The pigs were fed diet containing 16.5%,15.5%,14.5%,13.5% and 12.5% crude protein,amino acid were added in low ptrotein diets. The results indicated that 14.5% crude protein supplementation with lysine and methionine could increase performance and decrease crude protein content in fecal,feed cost was increased.The second experiment was conducted to study the effects of interaction of low phosphorous and low protein diet on performance and phosphorous content of fecal in growing pigs.300 growing pigs(Duroc×Landrace×Large white) were divided randomly into control and four groups by sex and weight Each group had three repeat with twenty piglets.The results indicated that growing pigs fed diet containing 14.48% crude protein and 0.40% phosphorous ,adding phytase and non-starch polysaccharides enzyme preparation. feed gaion ratio was decreased and dialy gain was increased, phosphorous content of fecal was decreased.The third experiment was conducted to study the effects of interaction of low phosphorous,low protein and organic trace mineral on performance in growing pigs.240 growing pigs(Duroc×Landrace×Large white) were divided randomly into control and three groups by sex and weight Each group had three repeat with twenty piglets.The results indicated that low phosphorous,low protein and low organic trace mineral diet had no significant effect on performance,the trace mineral content was decreased in fecal.The fourth experiment was conducted to study the effects of probiotics on performance in low protein,low phosphorous and low organic trace mineral.360 growing pigs(Duroc×Landrace×Large white) were divided randomly into control and three groups by sex and weight Each group had three repeat with twenty piglets.The results indicated that perfomance was increased and pork achieve green food standard by Bacillus subtilis substituted flavomycin.In conclusion, environmental protection diet in growing pigs was 14.5% crude protein,0.40% phosphorous,low organic trace mineral and adding Bacillus subtilis.
