Pepsin is an enzyme needed to breakdown protein in food for example, amino acids and peptide substances then they are absorbed in the intestinal lining. chymotrypsin and trypsin the other enzymes that help break down protein.
Cows
Cows need protein in order to create milk and stay healthy. The proteins are broken down by microbes in the rumen and then into amino acids so it can be used in the cows body. They are in grains and similar sources of grains. More amino acids can be added to their diet so more can be used in the body.
Protein is essential and is seen in all cell membranes (hooves, muscles, hair and skin). They are structural components and help with muscle contraction, gene expression, metabolic regulation, enzyme catalysed reaction, and immune function. Actin, tubulin, myosin allow muscle contraction to occur. The majority of enzymes and hormones rely on protein to stay alive.
Cows get protein from mixed grains that they eat and some in grass and vegetables because they are herbivores so they cannot obtain it from meat. Every protein are made up of simple unit’s amino acids. There are hundreds of amino acids protein only has 20. 10 of these amino acids are essential in the diet because tissue synthesis is not enough to meet metabolic requirements (Pasquale, 2007).
Dogs
The dog’s teeth are made to grip and tear than to grind and chew, carbohydrates are broken down in their mouth. The meat goes down the oesophagus by the mouth to the stomach the food stays there for 4-8 hours. The stomach is acidotic allows for breakdown of meat protein. the contents in the stomach are broken down once they reach the small intestine, where the most digestion occurs.

If a dog has kidney disease they are carefully monitored to a particular amount of protein intake.
(Hoove, 2010).
Mealworms are the best protein for bearded dragons you must give the correct amount otherwise it can cause them health issues such as not been able to digest the food correctly. Feed them crickets twice a week as much as they wish in a 5- 10 minute period. Reptiles require 30-60% protein in their diet. However green iguanas need 28%. 18 to 20% for meat-eaters and 11 to 12% for plant-eaters (Kaplan, 2001).
Cats
Lions and other cats require the amino acid Taurine in their diet this is because they cannot maintain the amount they require in the body. If they do not get it they will get deficiencies in Taurine because the cat to be ill until the level is increased.
