Liquid Feeding

What is liquid feeding?

Liquid feeding is the use of a diet that is prepared from either liquid or dry components, which are thoroughly mixed with water in a dedicated mixing tank, then transported to the pig. It is possible to simply add water to a regular complete feed mix, but the real advantage of liquid feeding is being able to utilize a wide variety of valuable and low-cost feed components; such as whey, co-products from the food industry or high moisture corn.

The entire mixing process is under computer control and the resulting feed will be 20 to 30% dry matter. Liquid feeding should not be confused with a wet/dry feed system, where water and feed are provided separately to the feeder and the pig chooses how much of each to consume. While not extremely common in the United States, liquid feeding is very popular in other areas of the world, particularly in Europe and parts of Canada.

HydroMix Liquid Feeding System for Sows

Big Dutchman’s HydroMix Liquid feeding system can be applied to feed sows in all production phases:

  • For gilts kept in groups
  • For empty and pregnant sows in individual stalls
  • For empty and pregnant sows in free-access stalls
  • For sows housed in groups with CallMatic ESF stations
  • For lactating sows in farrowing pens
Why feed sows liquid?

Economic benefits

  1. Utilize valuable low-cost co-products to significantly reduce feed costs
  2. Improve profit and efficiency with fast payback

Benefits for sows and production

  1. Sows love liquid feed: therefore higher feed intake and proven better feed conversion compared to dry feeding
  2. Feeding liquid during gestation is the best possible preparation for high feed intake during lactation
  3. Despite restrictive feeding, sows are more satisfied and less stressed during gestation
  4. More accurate individual feeding results in high feed intake during lactation
  5. Increased dry matter intake of lactating sows
  • minimal loss of body fat and protein
  • shorter weaning-to-estrus period
  • increased litter weight

    How does higher feed intake during lactation effect litter weight?

    Example for 23% higher feed intake:

 Dry FeedLiquid Feed
Average feed intake13 lbs16 lbs (+23%)
Additional milk production per day +3lbs (1:1)
Additional litter weight per day: 0.75lbs
Litter weight increase after 21 days: 15.75lbs

Health and Hygiene benefits

  1. Liquid feed has a positive influence on overall pig health
  2. Reduction of dust and better overall hygiene: healthier atmosphere pigs and caretakers

Practical benefits

  1. Convenient pipeline system adaptable to any building lay-out
  2. High accuracy of feeding
  3. With multi-phase feeding, automatic adjustment of diets to nutritional needs
  4. Excellent monitoring and control over production
  5. Reduced cost of labor

Typical Co-Products and homegrown feed

  • Whey or other products from the dairy industry (yogurt, ice cream, etc.)
  • Beer yeast
  • Starch residues
  • Potato products
  • Bakery products
  • Ethanol residues (CDS)
  • Home-grown feed such as high moisture corn
