ANS 313 FINAL EXAM 1998 Name: I am interested in being a TA for this class next year. YES MAYBE NO TRUE/FALSE 1. T F Near-Infrared Reflectance (NIR) works okay when analyzing pure alfalfa haylage for protein but wet chemistry should be used for analysis of minerals. 2. T F Of the 6 major nutrients, the only one that is not absolutely essential is carbohydrate. All the others are needed for maintenance of life. 3. T F Unless an animal practices coprophagy, all the microbial activity in the hindgut is basically unnecessary and the animal would almost be better off with no fermentation compartment. 4. T F The major difference between wheat straw and corn grain in their ability to supply usable energy to an animal is that corn has more lipid. 5. T F The Heat Increment of Feeding is wasted energy. However, if the environmental temperature increases above the upper critical temperature, this heat will be very useful. 6. T F Animals can synthesize glucose from fatty acids. 7. T F The major source of blood glucose in a dog after a high protein, high fat meal is dietary amino acids. 8. T F Generally, we consider that there are ten AA which are “essential” and are needed in an animal’s diet; however, in some young animals, there might actually be more than ten that are “essential”. 9. T F After entering a cell, lysine will either be used as a building block in protein synthesis or stored in the free L-lysine-hydrochloride form. 10. 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. 11. T F A major goal of controlled, intensive grazing systems is to match grazing activity with vegetative growth so that the herbage is eaten when it is most nutritious. 12. T F A major goal when making silage is to get the pH above 8 as quickly as you can. 13. T F A pig will eat more when the effective ambient temperature is below its thermoneutral zone. 14. T F Low blood non-esterified fatty acid concentrations in most monogastrics stimulate hunger. 15. T F Generally, as total food dry matter intake per day increases, the rate of passage increases and the total amount of food digested decreases. 16. T F Generally, as total food dry matter intake per day increases, the rate of passage increases and the percent of food digested decreases. 17. T F The compensatory gain phenomenon that occurs when growing cattle are switched from mostly forage to mostly grain diets seems to contradict the lipostatic theory of feed intake regulation. 18. T F The trans fatty acids found in partially-hydrogenated oil products (such as margarine) are just as much of a concern for human health as the saturated fatty acids found in butter. Multiple Choice 19. ___ Adequate effective fiber in a ruminant diet is necessary to stimulate rumination, which in turn stimulates salivation, which in turn is necessary to do this: a. decrease blood volume b. remove phosphorus from blood c. elevate rumen pH d. lower rumen pH 20. ___ All metabolic reactions must be thermodynamically favorable.
