The invention discloses a synbiotic
feed additive for growing and fattening of pigs. The synbiotic
feed additive is prepared from composite
probiotic agents,
maltodextrin, isomaltooligosacharide, glucose,
citric acid, composite vitamins, composite trace elements,
charcoal, attapulgite, leguminosae,
dioscorea opposita, poria cocos,
atractylodes macrocephala rhizomes, dried unripe fruits of citrus aurantium, common vladimiria roots, Chinese thorowax, dried ripe fruits of
crataegus pinnatifida, oblongleaf
kadsura stems or roots and
bidens pilosa. The invention further provides an application method of the additive. During the growth and fattening period of pigs, the synbiotic
feed additive for growing and fattening of pigs is added to a feed according to the addition quantity of the synbioticfeed additive to the
body weight of fattening pigs being 0.1-5% for feeding. Through adoption of the synbiotic feed additive for growing and fattening pigs and the application method disclosed by theinvention, the weight increment speed of the
body weight of the pigs can be increased, the
lean meat proportion is increased, the nutrients are comprehensive, the feed feeding quantity can be reduced, the
utilization rate of the feed can be increased, the
growth speed of the pigs is high, the meat quality is bright red, tender in nature and good in mouth feel, the
economic benefits are increased,and the synbiotic feed additive has good application prospects.
