ANS 313 FINAL EXAM 1999 Name: 1. I am interested in being a TA for this class next year. YES MAYBE NO (any answer gets 1 pt) TRUE/FALSE 2. T F In general, the slower the rate of passage of digesta through the tract, the greater the extent of digestion. 3. T F The major difference between corn grain and tallow in their ability to supply usable energy to a cow is that tallow is simply more energy-dense even on a gross energy basis. 4. T F Comparing the energy of 1 kg of wheat straw and 1 kg of corn grain fed to a horse, the ME but not the DE would be greater for the corn than the straw. 5. T F Metabolic body weight (BW in kg) is BW .75 ; it correlates with the fasting heat production of different sized mammals 6. T F Because of the Heat Increment of Feeding, the range of temperatures for the thermoneutral zone of a fed animal is lower than that of a fasted animal and the fed animal is comfortable in a colder environment. 7. T F Animals can synthesize glucose from fatty acids. but not fatty acids from glucose. 8. T F Lipids that contain more saturated fatty acids have higher melting points than those with mostly unsaturated fatty acids—in other words, they will more likely be solid at room temperature. 9. T F Heating a feedstuff will generally make protein less degradable in the rumen. This is good for a high- producing dairy cow unless it also makes the protein less digestible. 10. T F Animal proteins usually have higher biological values than the proteins of cereal grains. 11. T F The protein to energy ratio in a swine diet should increase with age. 12. T F If an animal is fat, it is in positive energy balance. 13. T F Increasing the activity level of a horse increases its energy requirements. 14. T F In general, profitability is greatest when growing and finishing market animals are fed cheap diets to minimize feed costs rather than spending any extra money to maximize gains. 15. T F The compensatory gain phenomenon that occurs when growing cattle are switched from mostly forage to mostly grain diets directly contradicts the lipostatic theory of feed intake regulation. 16. T F Although you don’t need much of it, a little arsenic is actually good for you. 17. T F One reason growing animals usually handle cold weather better than hot weather is that they tend to eat more when it gets hot but eat less when it gets cold. 18. T F Animal products are a great source of phosphorus and sodium, two minerals that many American college-aged women don’t get enough of. 19. T F The entire lifestyle, not just eating habits, of most people in developed countries is resource- demanding. 20. T F When it comes to food, the best advice is to eat a variety of foods, to eat each in moderation, and to eat when you are hungry but quit when you feel satiated. Multiple Choice
