Cuddling is a kind of regurgitation. Sheep cud pre-chewed food again and again to extract more nutrients. So, they throw up the gastric content. This is a normal behavior of sheep. This is usually observed by the sheep owners.

1. RUMINAL ACIDOSIS / Grain Poisoning

this is also called grain poisoning. This condition occurs in sheep when they eat too much grain. As you know the pH of a rumen is acidic, too much grain means too much carbohydrate consumption. The rate of fermentation becomes high due to the large amount of carbohydrates present in the diet.

This all leads to the overproduction of lactic acid (a product of carbohydrate fermentation) that causes a severe drop in the rumen’s pH. This all causes rumen acidosis. Your sheep can show signs of throwing up, nausea, and severe dehydration.

In poisoning, sheep throw up frothy feed material out of their mouth. Additionally, if she ingests any foreign body such as nail, grits, etc through the feed, she will try to throw it out. Remember, if your sheep ingests any sharp or pointing material then it can put her life in danger.

These situations can be so much serious and life-threatening in lambs. So, contact your veterinarian without delay.

Grain Overload / Acidosis


This is an irritating and confusing condition that is mostly found in young sheep. Dysphagia(unable to eat anything) is one of the major causes of this. This occurs in lambs when their esophageal groove is not properly functional or any infection establishes. Any sharp or pointing object can also cause this cud spilling condition in lambs.

It has been discussed that there are various factors that cause throwing up in sheep such as acidosis, poisoning, or any other foreign object that goes in the rumen.

This is important to observe the overall health of sheep and keep an idea about what is the actual cause of throw-up. It is also wise to stay in contact with your veterinarian and to take his consultancy to deal with such situations.
