The utility model relates to the technical field of animal houses, in particular to a breeding fence for sows in a lactation period, which supports an equipment main body through a supporting device, facilitates cleaning of pig manure, adjusts the temperature of a local area in the supporting device through a temperature control device, and facilitates feeding of the sows by an operator through a feeding device. The condition that food is arched out to the body of a feeding person due to the fact that sows arch food in the feeding process is reduced, and the practicability of the device is improved; comprising a supporting device, a temperature control device and a feeding device, the temperature control device is installed on the supporting device, and the feeding device is installed on the supporting device.

The invention discloses a lactating sow feed additive and a preparation method thereof, and relates to the technical field of lactating sow feed. The preparation method comprises the following steps: mixing vitamin E and a rosemary extract in proportion, emulsifying to prepare an emulsion, compounding with a polylysine solution, curing with calcium chloride, and centrifugally drying to prepare an inner core; then mixing acid protease with sorbitol to prepare a stable solution, compounding the stable solution with the inner core, and drying to obtain a composite core; and finally, preparing a coating solution from cellulose acetate succinate and glycerol, and carrying out bottom spraying type spray coating to prepare the double-layer microcapsule.
