Have you ever wondered about how a goat\u2019s stomach works? Many new goatkeepers don\u2019t actually realize quite how amazing a goat\u2019s stomach is. But, in reality, your goat\u2019s stomach is an evolutionary work of art, and it\u2019s truly amazing how the goat\u2019s stomach works! With this thought in mind, today, we\u2019re looking at some key questions you may have wondered, including how many stomachs a goat has, how a goat\u2019s stomach works, and the like.<\/p>\n\n\n\n
As a ruminant, a goat only has a single stomach \u2013 but we often say that they have \u201cfour stomachs\u201d due to their stomach\u2019s four-chambered design. The goat\u2019s \u201cfour stomachs\u201d are the reticulum, the rumen, the omasum and the abomasum.<\/p>\n\n\n\n
All goats have a four-chambered stomach, and this is the same between all species of goats. The ruminant bioplan evolved around 50 million years ago, so you would have to look farther back than this to find ancestors of the goat that did not have multiple stomach chambers.<\/p>\n\n\n\n
However, it\u2019s worth noting that the exact size of the stomach will vary between goats of different ages, breeds, and the like. Furthermore, a heavily pregnant doe or nanny will have a smaller stomach capacity than other animals since the growing goat kids can place pressure on her stomach.<\/p>\n\n\n\n
The purpose of having multiple stomach chambers is simple: it allows goats \u2013 and other ruminants \u2013 to make much better use of rough, coarse, and nutritionally low feeds. If you\u2019ve ever seen a goat munching happily on a twig or a little bit of fresh barley straw, you\u2019ll see what we mean here! <\/p>\n\n\n\n
As such, ruminants are much more efficient at using poor forages. In fact, without their rumens and advanced stomach structure, it\u2019s unlikely that ruminants and goats would be able to survive in so many rough, seemingly inhospitable terrains. It\u2019s worth noting, though, that a lot of this success is owed to the immense population of microbes living within the rumen; as such, as birth, a goat still has a sterile rumen, and so the rumen does not function until the goat is a little older. That\u2019s why you cannot hope to wean a goat kid until its rumen is fully developed; it is immature and ineffective at birth!<\/p>\n\n\n\n
After food has passed through the stomach, it\u2019s already more digested than in many other herbivorous and omnivorous species. Thereafter, the intestines help digest and absorb any remaining minerals, allowing goats to make use of poor forages to the best of their abilities.<\/p>\n\n\n\n
Goats are ruminants, alongside many other common herbivorous species such as cattle, deer, and sheep. The ruminant is largely defined by its incredibly well-adapted stomach structure, which makes it highly efficient at breaking down and digesting highly coarse, fibrous, and hard-to-digest foods, such as grasses, that many other species struggle with.<\/p>\n\n\n\n
As we\u2019ve already mentioned, the ruminant\u2019s stomach structure has four chambers: the reticulum, the rumen, the omasum, and the abomasum. This differs from most other animals, where the stomach structure is much simpler; for example, our own stomach is just a single large \u201csac\u201d where acids begin to break down our food.<\/p>\n\n\n\n
The four chambers of the goat\u2019s stomach each carry out a different role. The reticulum stores food after it\u2019s swallowed (we\u2019ll look at this in a minute). The rumen acts as a fermentation vat and is by far the largest part of the stomach, where a massive community of bacteria ferment the forage and convert it into more easily digestible materials (VFAs \u2013 volatile fatty acids). Next, the omasum absorbs water from the feed. Finally, the food then passes into the abomasum (often called the \u201ctrue stomach\u201d where standard digestion through hydrochloric acid and digestive enzymes takes place on the already-broken-down matter.<\/p>\n\n\n\n
In contrast, in other animals, the stomach process is far simpler and mainly relies on digestive enzymes and acids. As such, by the time plant matter reaches the ruminant\u2019s true stomach, it\u2019s already much more broken down and easily digestible.<\/p>\n\n\n\n
By contrast, species such as horses work differently. Horses are hindgut fermenters; they still ferment their food to get the most from it; however, this occurs at the end of their digestive tract in an enlarged cecum. As such, they are much less able to make use of roughages than a ruminant.<\/p>\n\n\n\n
It\u2019s worth considering that the goat\u2019s ruminant digestive system is very different from our own, since food doesn\u2019t stay solely in the stomach before passing along the rest of the digestive tract. In fact, your goat will regurgitate some of their newly-eaten food when they feel comfortable and happy to re-chew it. This process is called chewing the cud.<\/p>\n\n\n\n
Some people mistakenly believe that non-ruminants also chew the cud; for example, Chris Packham from the BBC once claimed that horses and cattle both chew the cud. However, in reality, only ruminants are able to actively chew their cud. Since horses are actually classed as hindgut fermenters, they do not have the ability to chew their cud.<\/p>\n\n\n\n
If you\u2019ve ever wondered, how many stomachs does a goat have, the answer is actually a little more complex than you may have realized. Indeed, by definition, a goat only has a single stomach. However, we often claim that goats and other ruminants have four stomachs since their four-chambered stomach design means each section does something a little bit different.<\/p>\n\n\n\n
It really is quite amazing to see a goat in action, digesting roughages and course leaves that look simply inedible to us. However, as with other ruminant species, they can do this thanks to their \u201cfour stomachs.\u201d Hopefully, today\u2019s guide will have helped you understand more about the goat\u2019s four-chambered stomach, how this works, and what this means for their health and wellbeing.<\/p>\n","protected":false},"excerpt":{"rendered":"
