Study On Application Of Oil Origanum And Flavomycin In Dairy Cattle Production

The groWth promoters of anibiotic to domestic animal has been discoveredby Stockstad et al in tWenty forties. Primarily, antibiotic was mostly used inpoutw and stock.with the raPid development of cow industy and the deePerresearch in dairy cattle in the world, antibiotic has been widely used to retrainthe enter pathogenic microorsanism and to improve the digest absorb power ofcellulose in ramen in USA and E.E.C (Europe Economic Community).NoWadays, antibiotic as growth promoters was not widely tised in dairy cattle forthe POor cow industry in our country not to say the on residual additive such asRopadiap Flavomycin. It is necessny to research and develop a new growthpromoter additive specially used is dairy cattle to accelerate the develope of ourcounny cow induStryThere are 20 China HoIstein cows used in this experiment divided intO threegroups. The whole feed experiment period is 60 days. The treatment and cownumber of each group is as fol1ows: Group l (OiI origanum and flavomycin.7),GrouP II (Oil origanum and Monesin,7) Group III (Control grouP,6). Theresult of the exPeriment is: there are improvement obviously of milk production,milk fat otio,milk protein ratio of GI,G H compared with GnI, The difference issignifican (P<0.05).The milk production, milk fat ratio,miIk protein ratio anddry matt6r improved of GI,G II are separate 28.l2% and l7.92%, l4.62% andl4.20%, l2.50% and ll.92%, 5.74% and 5.84% compared with GIII. The milkproduction and quaity of GI,G II are suPer than GflI. And GI is a bit super thanG IIbut there on significan different betWeen GI and G II(P<0.05).GI has asignificam effect on prevent and cure subclinical mastitis.Oil origanum is exstract from a kind of plan named oregano, Itscommodity name is Ropadiar Oil origanum is an ideal additive for itS no drugwithdraw Period, and obviously improved miIk production and quality effective-2-to the subclinical mastitis. With China joined the World Trade Organization and the wove improving people's living condition, the move claimed for green and no polluted food Oil origanum for its green, high effect, safety is suit for this demand. This research is to synthesis value the Oil origanum and flavomycin effect milk production and quality subclinical mastitis so as to offer the science basis of application of Oil origanum et al to accelerate milk industry healthy development in China.Postgraduate: Liguo Yuan Major: Basic Veterinary MedicinTutor: Prof. Hengmin Tong...
