The present application relates to the technical field of feed additive, and discloses a lactation-promoting functional feed for lactating sows containing high-efficiency plant lactogenic factors, which is made of the following raw materials: sodium-based montmorillonite, fenugreek extract, motherwort extract, ion intensity regulator, lysophosphatidylcholine, tributyl citrate and high-purity silicon dioxide, and is prepared through the following steps: mixing and drying sodium-based montmorillonite with the ion intensity regulator to prepare a regulation carrier; adding fenugreek and motherwort extract and mixing them by strong shearing to form an active core; atomizing and spraying a mixture of lysophosphatidylcholine and tributyl citrate on the surface of the core to form a functional layer; and finally adding high-purity silicon dioxide and mixing uniformly to obtain the feed. Through the construction of the structure with ion-pretreated montmorillonite as the core and the functional layer as the shell, the present application realizes the protection, sustained release and efficient absorption of the active ingredients, and improves the bioavailability.

The application discloses a functional feed additive composition for improving lactation performance of lactating sows and uniformity of piglets and application thereof, and belongs to the technical field of livestock feed additives. The additive is composed of a core functional component, a composite modified slow-release functional agent and a carrier auxiliary material according to percentage by weight. The application can improve the lactation yield of sows by more than 15% through synergistic effect of components, shorten the weaning estrus interval, reduce the standard deviation of piglet body weight by more than 20%, and greatly reduce the weak piglet rate and the diarrhea rate. The process is suitable for large-scale production, the economic benefit is remarkable, and the application is suitable for feeding of lactating sows in large-scale pig breeding.

This invention relates to the field of sows, and more particularly to an intelligent feeder for lactating sows. The feeder includes a support frame, a platform (3) arranged above the support frame, an auger motor (1) arranged on the platform (3), the auger motor (1) being able to drive the auger (4) to work; a funnel (2) arranged on the auger (4), the outlet at the end of the auger (4) being a pipe opening (5), the pipe opening (5) being arranged downwards; a hole arranged on the platform (3) for accommodating the pipe opening (5); the support frame includes casters (7) below; a downward-facing support arm (13) is also arranged on the platform (3), the end of the support arm (13) being provided with a caster (7); the caster (7) is able to travel along the groove (9) on the track wall (5) of the feeding area; the auger motor (1) includes a switch.

The present application relates to a kind of compound acidifier for improving the feed intake of lactating sow and its preparation method, belong to the technical field of feed additive.The compound acidifier includes wall material and core material, the wall material includes cystine-gamma-polyglutamic acid and arginine-chitosan;The core material includes organic acid, organic acid salt and fermentation broth.The compound acidifier of the present application uses cystine crosslinked gamma-polyglutamic acid and arginine grafted chitosan as wall material, forms microcapsule with intestinal target release function by wrapping organic acid, can effectively improve the utilization efficiency of acidifier and the feed intake of lactating sow.
