In summary: I think that the chicks of gouldian finches benefit more with their parents than foster parents because they get the natural flora and fauna of the gut.

I was reading a post on a bird forum earlier and someone mentioned that the chicks of gouldian finches benefit more with their parents than foster parents because they get the natural flora and fauna of the gut; however, another poster said that this wasn't as important in birds as they have a different system to animals. Anyway, pick that part to bits if you wish, but my actual query is: what is the flora and fauna of the gut?

That question applies to humans, animals, birds... whatever. I suppose I could've easily looked it up, but I'm sure the posters on here will give a more thorough response.

The flora and the fauna of an animal refers to the microorganisms that forms a symbiotic relationship with an animal. the flora will be different from species to species and from individual to individual. Some organism living in the gut are unique to given specie and can only be isolated from that specific specie.

Cows have a very special flora/fauna that is very complex. The rument has predator fungi and protozoan that feed on the other microorganism. Also, without this flora cows and other ruminant would die because they cannot digest cellulose and the flora does it for them.

The flora and fauna found in the gut generally aloows the host to more efficiently utilize food energy. It is usually a very important aspect of the digestive system in animals that are vegetarians, like the cow mentioned by iansmith. One might also say that it provides some means of resistance to harmful, invasive microbes, since the good bacteria are already established and therefore have a "homefield advantage" over the potential invasive species. There are different ways of establishing the gut flora, one common means is coprophagy, or consuming the fecal matter of an individual that already has an established system. Such practice would be a reason to keep a developing animal with it's parents.

As far as birds, and specifically finches, I'm no expert, but I found the following link that describes the "sterile bowel" of more evolutionarily advanced species of birds. It's an interesting theory, but I couldn't find much else about it on the web therefore caveat emptor.

Thanks both. Very interesting articles, too.
 

1. What is the role of flora and fauna in the gut?

The flora and fauna in the gut, also known as gut microbiota, play an essential role in maintaining our overall health. They help with digestion, absorption of nutrients, production of vitamins, and protection against harmful pathogens.

2. How is the flora and fauna of the gut affected by diet?

Diet can greatly impact the composition and diversity of gut microbiota. A diet high in fiber and plant-based foods can promote the growth of beneficial bacteria, while a diet high in processed foods and sugar can lead to an imbalance and decrease in beneficial bacteria.

3. Can the flora and fauna of the gut be altered?

Yes, the composition of gut microbiota can be altered by various factors, such as diet, antibiotics, stress, and aging. This can result in an imbalance of bacteria, which has been linked to various health conditions.

4. How does the flora and fauna of the gut affect our immune system?

The gut microbiota plays a crucial role in regulating our immune system. They help educate the immune system, and an imbalance of gut bacteria has been linked to autoimmune diseases and allergies.

5. What are some ways to promote a healthy flora and fauna in the gut?

Eating a balanced diet rich in fiber and probiotic foods, avoiding unnecessary use of antibiotics, managing stress levels, and incorporating physical activity into daily routines can help promote a diverse and healthy gut microbiota.
