Hi Click,
A lot of people think that once an axie's (or any animal's) metabolism slows down, every system slows down, this is actually not true.
For example, in colder environments, our peripheral blood circulation (skin) slows down hence we get the palor. What happens is the blood actually gets preferentially shunted towards the vital organs such as the brain, the liver, the heart, the kidneys etc. This increase in circulation to these organs actually allows them to work better, concentraing and focusing on regeneration and repair.
In an impacted and fridged axie, it is definitely true they will have decreased appetite. However, continual feeding has many advantages. Firstly, the enterocytes or intestinal cells gain their nutrition for repair and growth directly from ingested food. Secondly, feeding will stimulate regular peristaltic movements along the gastrointestinal tract and prevent a condition called paralytic ileus. In all, feeding will ensure healthy functioning of the intestinal tract. Feeding will obviously also provide nutrition for immunity, energy and prevent the axie reaching terminal starvation point.
The reason why we offer food daily is because we would not know when the axie 'feels' like eating. It is more of a "just in case' measure. I do tend to recommend mash food while fridged because they are much easier to digest.
Because the act of eating and even attempting to eat will stimulate the gut's peristaltic movement, it will facilitate the passage of impactions. Furthermore, the gut lining will become more 'moist' from activating mucus producing cells called goblet cells. The increased lubrication along the gut will further help the axie pass out the offending material.
Cheers.
