ObesityWhat factors influence body weight gain in pets?- Calories, exerciseWhat are the repercussions of obesity to the animal?- Heart disease, reduced mobility2. Safe rate of weight lossAssume you have a 40kg dog that is 10kg overweight, according to your veterinarian. A safe rate of weight loss is 1.5% of current body weight (40kg) per week. How long will it take this dog to lose 10kg?- 16.67 weeks- .015/wk = 0.6 kg/wk- 10kg x .6kgHow many calories should this dog be fed per day? (Assume that this dog is at maintenance, feed at 60% of requirement.)- 750kcal/dayCarnivore/Omnivore Digestive anatomy – List the function AND draw a diagram including the 5 Parts below.1. Mouth:a. Chews2. Stomach:a. Digests, breaks down into smaller pieces3. Small Intestine:a. Absorption of nutrients, more digestion4. Cecum:a. Fermentation, absorbs water5. Large intestine:a. More fermentation, absorbs waterMeat only diets – dog/catRefer to the table labeled, “Meat! It’s (Not Only) What’s for Dinner!” on the slides for today. Do you think that an all meat diet provides all necessary nutrients for a 20-lb dog? Why or why not? - No, the calcium to phosphorus ratio is too much. The calcium percentage should be higher than the phosphorus percentage; in the meat diet it is reversed. There is 4 times the amount of protein that they need. The calcium and iodine levels are too low which can lead to thyroid problems.Sustainability of pet diets1. Describe sustainability with regard to pet food. What issues are important?- Sustainability has to do with a food system providing sufficient energy and essential nutrients in order to maintain good health.
