Why you should feed your animals wet feed

Wet feed is the byproduct of other food productions that provide an alternative to traditional dry feed. These products ar often cheaper and have been noted for their positive effects for livestock.

What is wet feed

Wet feeds, particularly in TMR (total mix rations), are a great way to provide a nutritious diet to livestock. Many of the byproducts in commercial food production ferment during the storage and making process. The products used as wet feed have properties where sugars and starch decrease and the lactic acid, acetic acid and alcohol content increases. These byproducts are particularly useful in the diet of pigs and cattle.

What are the wet foods available

Wet feeds come in a variety of formats with different benefits being drawn from the different types of productions they come from.

Brewers grain

Thanks to the use of concentrated hops in beer making, which aren’t as bitter as regular hops, brewers grain is an enjoyable meal for pigs and cattle. Bewers grain improves the digestion of the cow thanks to the naturally occurring high content of rumen by pass product. The protein produced also helps reduce the concentration of fatty acids in the cow’s rumen, keeping your cow fit and healthy. Brewers grain is also a great source of fibre, which is helpful in pig farming. Sow’s require a high fibre diet while in their gestation period, making brewers grain an ideal choice of diet. The byproduct of this brewers grain is also noteworthy as it contains alcohol content unfit for human composition but safe for pigs to digest, helping with silence in the pig stable.

Wet cereal grains and feed products

Another source of wet food is the maize processing industry. This is thanks to the run off of starch and gluten, with the resultant effect being a high volume of fibre and gluten proteins. This produces a great source of protein and fibres and is noted for its positive effects on cattle and pigs. It has positive impacts on the growth of cattle and sow, with products that have used corn starch enzymes during production creating easily digestible fats and dextrose.


Potatoes have properties that make their byproducts beneficial to both cattle and pigs, but the variation means certain feeds are better for the particular species. For cattle, potato scraps are a great choice to help with digestion. Potato scraps consist of potato parts not suitable for deep fried products. The high levels of starch in these leftovers produces a high level of rumen by pass.However, the starch levels are unfit for pigs, who require cooked potatoes. These potatoes are often leftovers of items fried and contain a high amount of fat because of the cooking oil used. This cooking also releases the starch and makes them safe for ingestion for the pigs. Steamed potatoes offer an alternative that both cows and pigs can have. Because of the removal of peels with steam, the starch content is lowered and is made suitable for pigs. The juices of potato production is also a high source of protein that can be acquired for protein feeding young animals.

How to store

Conserving wet feed is important to keeping it for prolonged periods of time. Wet foods have a high concentration of liquid and can be vulnerable to bacteria. Cleaning the food storage area regularly and the addition of specific acids, either through adding the acid or natural acidification, can prevent this from happening.

What machine should you use

Because wet food rations are used in TMR, a mixer is required. All mixers by AusMix have been built with the ability to process heavy wet feed. This is thanks to the Fibre-X Auger which is the centrepiece of every AusMix mixer. This not only is useful in processing heavy wet feed, but also helps get the optimal amount of fibre from the feed.
