Method of feeding the cattle with feed additives that increases beef production and reduces liver abscess
The present inventions relates to a method of increasing beef production in cattle with feed additives, comprising feeding cattle with feed, comprising an effective amount of an ionophore in combination with a macrolide antibiotic, and thereafter feeding cattle with feed, comprising zilpaterol and essentially no ionophore or macrolide antibiotic for the succeeding about 20 to 40 days.
1. A method of increasing beef production in cattle with feed additives, comprising:
feeding cattle with feed, comprising:
an effective amount of an ionophore in combination with a macrolide antibiotic, and thereafter
feeding cattle with feed, comprising:
zilpaterol and essentially no ionophore or macrolide antibiotic for the succeeding about 20 to 40 days.
2. A method of reducing feed intake of cattle and maintaining beef production, comprising:
administering to cattle feed an effective amount of an ionophore in combination with a macrolide antibiotic up to the last 20 to 40 days of a 90- to 225-day feeding period before harvest;
administering for the last 20 to 40 days of the 90- to 225-day feeding period an effective amount of feed, comprising:
zilpaterol as the single β-agonist compound present with essentially no ionophore or macrolide antibiotic.
3. A method of reducing incidences of liver abscess in cattle fed with feed additives, comprising:
administering to cattle feed art effective amount of an ionophore in combination with a macrolide antibiotic up to the last 20 to 40 days of a 90- to 225-day feeding period before harvest;
administering for the last 20 to 40 days of the 90- to 225-day feeding period an effective amount of feed, comprising:
zilpaterol as the single β-agonist compound present with essentially no ionophore or macrolide antibiotic,
wherein the reduction of liver abscess is compared to ionophore and macrolide antibiotic fed cattle throughout 90- to 225-day period.
4. The method according to claim 1 , wherein the ionophore is monensin and the macrolide antibiotic is tylosin.
5. The method according to claim 2 , wherein the ionophore is monensin and the macrolide antibiotic is tylosin.
6. The method according to claim 3 , wherein the ionophore is monensin and the macrolide antibiotic is tylosin.
