♪ (music) ♪ Aaron: Ionophores are a nutritional biotechnology used commercially in beef cattle and poultry with limited use in lactating dairy cattle diets Ionophores are commonly fair to all classes of beef cattle resulting in increased feed efficiency and improved average daily gains They are commonly fair to broilers, broiler breeders, and replacement pollets to control the diesase, coccidiosis Examples of Ionophores used in the beef cattle industry include Menoshin, marketed under the trade name: Rumensin Lasalasin, marketed under the trade name: Bovatec and Lalamonsin, marketed under the trade name: Cattlyst Ionophones are classified as a polyether antibiotic in that they cause a shift in the rhema microorganism populations This shift in microbia population affects how feeds are fermented and creates a decrease in acetate production and an increase in propionate production Both are volatile fatty acids produced through rumen fermentation which along with butyrate are used as a primary source of energy for the ruminant animal Farm animals that are considered ruminants include beef and dairy cattle, sheep, and goats This increase in beneficial bacteria and protozoa through the use of an ionophore decreases the loss of energy through the production of methane gas and carbon dioxide during rumen fermentation Methane is a greenhouse gas that along with carbon dioxide are waste products of rumen fermentation that represent an inefficiency of that fermentation the addition of ionophores increases the efficiency of the use of ingested feed Thus increasing the overall energy status of the animal which leads to increased weight gain and stalker and backgrounder cattle and a reduction in the amount of feed required per unit of gain in feed lock cattle There is also a decrease in the incidents of bloat and acidosis in ionophores fed cattle Both of which inhabitant feed intake Additionally, ionophores are used to reduce the incidents of coccidiosis Which is a diarrheal condition caused by protozoa parasites that can have a negative impact on animal performance An added benefit of the use of ionophores is that they are a completely different class of compounds and will not contribute to antibiotic resistance in humans Today, we’re going to talk a little about the ionophores and the ionophores are a polyether antibiotic Uh that causes a shift in the ruma microbial population and basically makes the animal more energetically efficient uh, now we talked about polyether antibiotics and it can be confused with antibiotics that we might use in human medicine um And cause bacterial resistance This a completely different class of compounds uh that uh there is no antibiotic in the human world that uh that looks like this and so we don’t have to be concerned about this uh bacterial resistance problem The reason why we use ionphores is to increase weight gain in cattle that are on a high forage diet In cattle on a high energy diet will respond a little differently by increasing feed efficiency And, the net result of that is is that we will reduce some of the carbon emissions like in methane or carbon dioxide simply because we make the rumen much more efficent and causing the shift in microbial population and increasing the volatile fatty acid called propranate Uh one of the side benefits of using ionophores is that it does help control coccidiosis which is a parasite uh challenge on the animal And another benefit would be reduction in bulge uh which could be important to some of our feeder steers and some of our 4-H calves The other part of the benefit is I think of the ionophores is that it helps stabilize feed intake uh making the cattle a little bit more of a snack eater instead of a big meal eater And, that then helps reduce the amount of uh potential asidosis or the lowering of ph of a rumen on a high concentrate diet Ionophores are a nutritional biotechnology that shift rumen microorganism populations causing an increase in the efficiency of rumen fermentation by decreasing the losses associated with methane and carbon dioxide This increases feed efficiency and performance in beef cattle Additionally, ionophores are used to control coccidiosis in beef cattle and poultry diets Even though, they are considered an antibiotic, they are completely seperate from those used in human medicine And, do not contribute to antibiotic resistance issues Reference to any specific commercial product or corporation name is for general informational purposes only And that reference or the exclusion of an example does not constitute an endorsement, recommendation, or certification of any kind by Purdue University ♪ (music) ♪ This presentation was the production of the animal sciences department at Purdue University ♪ (music) ♪
