![]() At the lower (more acidic) pH levels needed to digest raw foods most bacteria is killed off but it will thrive at the higher (less acidic) pH levels that cooked foods can be digested at. Raw meat and bones need a pH of around 1-2 where as cooked foods and kibbles only need a pH of around 3-4, in terms of stomach acid this is a BIG difference. "Īs well as having different digestion rates raw and cooked foods need different levels of pH in stomach acid to digest. ![]() In group 3, the food was observed in the duodenum 30 min after ingestion and emptying was complete 240-360 min after ingestion. The stomach appeared to be empty 420- 480 rnin after eating. In group 2, the food started to enter the duodenum after 270 f 30 min. After 900 f 60 min the stomach appeared to be completely empty. In group 1, the food remained unchanged in the stomach for 480 to 600 min (mean 534 min) after completion of the meal. After food ingestion the animals had no access to water or to any other type of liquid. "The types of food used were (1) dried food with 10 % moisture, (2) canned food with 70 % moisture and (3) fresh food (fish) with 75 % moisture. If raw food is fed at the same time as kibble it can be held in the digestive tract for too long and this can lead to health and digestion problems due to bacterial growth.Ī study published in the Cambridge Journal states the following results to support this: If you choose to feed a mixed diet it is best to feed any raw foods in the morning and cooked meats, kibbles or wet foods in the evening ensuring that there is enough time between meals for the food to be digested properly. However it only takes around 4-6 hours for raw meats and bones to be digested. It takes around 14-16+ hours for processed kibble and wet food to be digested and around 8-10 hours for cooked meats. It is important to remember that animals digest raw, cooked and processed foods at different rates. We always recommend feeding a fully raw diet and would not actively recommend mixing raw and cooked diets, but people have fed mixed diets where this is more convenient, just be aware of the issues that can arise by doing this. Can I feed a mixed diet of raw and kibble or raw and wet/tinned food?
