Can you fight three defenses and four defenses all year round?

No, the injection time of the triple vaccine is spring (late February-early March) or autumn (late August-early September) every year.

Three-in-one and four-in-one vaccines for sheep are used to prevent diarrhea, sudden onset, enterotoxemia and rapid epidemic diseases in sheep. It is an infectious disease that must be prevented in raising sheep. The use of this vaccine must be strictly in accordance with the requirements. Vaccines are usually immunized from mid-February to the end of March. And generally choose to immunize in sunny morning or noon, and try not to vaccinate in rainy weather to prevent allergic reactions caused by decreased body resistance.

15-day-old lambs cannot be vaccinated with the triple vaccine, because the lambs are not weaned at this time, the interference of maternal antibodies will lead to poor immune effect, and the vaccine has a strong stress response to lambs, so lambs under 2 months old (before weaning) should not be vaccinated as much as possible.

Ewes can be injected 1 month before delivery, which can prevent lamb dysentery. Sheep in the third trimester are not recommended! Observe after vaccination, and take emergency measures as soon as possible to prevent unnecessary losses if there are adverse reactions.
