40 Withdrawl Period = Cattle Grubs = Insecticide = Time you must wait between giving a vaccine and using the meat or milk for human consumptionCattle Grubs =Larvae of the heel fly.Enter through heel, live in the spineThis is why you should not worm cattle between Nov 15 & Feb 15Insecticide =Process of TREATING cattle to remove parasites like lice
41 Why do we need to deworm cattle? Parasites (worms) make cattle unthriftyreduce weight gains, poor hair coats, reduce immunity to diseasesWays to Deworm AnimalsInjection - under the skinDrench - down the throatFeeding - ingest drugPour-on - on the back
42 Worm (parasite) Exposure Which type/class of animal is most affected by parasites?Newborn CalfFeeder Steer on PastureFeedlot SteerCow nursing a calf on PastureCattle get worms from eating grass. For the feeder steer on pasture the first exposure is the worst. Cows have had previous exposure so have some immunity.
43 Bovatec and Rumensin are examples Implant =Put a slow release hormone pellet in the ear of cattle (Ralgro, Synovex, etc..)Implants increase rate of gain, feed efficiencyand a leaner carcassProduct (not a hormone) added to feed to increase feed efficiency, rate of gain and acts to prevent coccidiosis.Ionophores =Bovatec and Rumensin are examples
