Most farmers give it weekly or fortnightly at the standard dilution of 1:20 to 1:50, added to water troughs or feed. Frequency can be adjusted to suit your conditions:
Regular use: Weekly or fortnightly, as an ongoing part of the diet.
Higher-demand periods: During dry seasons, when feed quality is poor, or in late pregnancy and around calving, foaling and lambing, keep to a regular weekly or fortnightly routine.
Good feed conditions: When pasture and feed quality are good, some farmers reduce to monthly or a few times a year.
It is a naturally cold-fermented liquid kelp supplement containing naturally occurring kelp compounds, such as alginates and fucoidans, along with minerals and the beneficial microbes produced during fermentation. This makes it a natural direct-fed microbial (DFM).
Kelp has a long history of use as a livestock feed ingredient, and many farmers add it to the diet as a natural source of minerals, particularly when feed quality is poor.
This Liquid Seaweed analysis shows its mineral content and microbial counts from previous testing.
