Provided are an altrenogest injection and a preparation method and use thereof. The altrenogest injection includes 0.1-35 g altrenogest, 0.01-70 mL of polyethylene glycol, and a balance of an alcohol solvent per 100 mL of the altrenogest injection. The altrenogest injection can effectively inhibit estrus of sows, synchronize the estrus cycle of sows, and is more convenient and efficient to use, and the dosage is more precisely controllable. A single injection can effectively inhibit the estrus of sows for 6 to 12 days, which significantly reduces the labor costs for large-scale farms.
A method of feeding swine, comprising injecting sows with an altrenogest injection to synchronize an estrus cycle of the sows, wherein the altrenogest injection comprises 0.1-35 g altrenogest, 0.01-70 ml of at least one polyethylene glycol, and a balance of at least one alcohol solvent per 100 mL of the altrenogest injection.
