Web Quizzes 1, 2, and 3 due by 12:00 AM, July 9, 2001. 

    Web Quiz 1 

• Concentrate on the six basic nutrients, their function and deficiencies and sources.  Know the chemical make up of the nutrients (e.g., carbohydrates contain C, H, and O; proteins contain C, H, O and N) .  DO NOT memorize chemical structures.  Know a little about their classification (e.g., monosaccharide vs. polysaccharide, etc.). 
• Skip section 2  under F on page 8, but understand how VFA are formed and their role in metabolism (see figure on page 10).  VFA are especially important to ruminants (see section C at the top of page 11).
• Lipids (fats) page 11. Nutritionally, the true fats are the most important.  Concentrate on what a true fat is, and the two groups of fatty acids; know the function of fat in the animals body (4 major functions on page 13).
• Protein - know the basic  unit of proteins (amino acids); understand why amino acids are classified differently; be able to distinguish between the essential and nonessential amino acids; SKIP section C on page 19, but the protein terminology section is very important; understand the concept of protein quality (see section on page 20). Understand the concept of protein quality in ruminants pages 20-21 and the role of ruminal bacteria and bypass protein. Have a basic understanding of the cause protein (amino acid) deficiency.  Have a basic idea how proteins are utilized differently by ruminants (cattle, sheep, goats) as compared with nonruminants (swine, poultry, humans, dogs, horses...).
• Ch. 1, pp. 1-24, sections I - V,  Related study  questions (pp. 48-50), Short answer questions (SAQs) pp. 50 1-4, 9. Problems p. 51 - #s 1-2.

    Web Quiz 2

• Ch. 1, pp. 24-38, sections VI - VII, Related study questions, SAQ  # 5 and Problem #3.
• Minerals and vitamins: mainly know the classification of each and concentrate on questions in III-A on page 50. Understand the concept of vitamin stability and how prolonged storage, heat damage, or UV exposure may decrease the nutritional value of a feed.
• Nutrients in Metabolism, p. 37.  Basically, you need understand what nutrients are being used for by the animal.  What nutrient(s) are the most critical in each process?

    Web Quiz 3

• Ch. 1, pp. 39-47, section VIII, Related study questions, SAQ # 10.
• Digestive systems (p. 38) Understand how animals classified (i.e., carnivores, herbivores...).  Explain the basic differences and unique features of the animals discussed.  Don't spend a lot of time on this section.
•  

Due on July 11, 2001.

    Web Quiz 4

• Ch. 2, pp. 55-60, section I, Related study questions, SAQ #4 and problems,1 and 2 (pp. 77-80)
• Why do we have laboratory procedures for measuring nutrient content of feeds?
• Basically know why each process of the Proxmate Analysis System (PAS)is conducted (i.e, what nutrient in being measured; refer back to the fibure 1-1 on page 2.
• Briefly describe each procedure involved in the PAS.
• Describe the Van Soest Method of Forage Evaluation.  See practice quiz for this section!
• What is the advantage of Near Infrared Reflectance Spectroscopy (NIRS) over more traditional methods of chemical analyses?  Can all nutrients be analyzed using NIRS?
• A lot of this information is covered in Exercise 1.

    Web Quiz 5

• Ch. 2, pp.60 -76, section I, Related study questions, SAQs  1, 2, and 3 and problems 3,4 and 5 ( pp. 77-80)
• Section G on page 60 is covered in Exercise 2.
• Outline the procedure for conducting a digestion or metabolism trial (see page 63, but skip section C).  In exercise 2, you will get experience doing digestibility calculations.

Due by July 12, 2001. 

• Exercise 1.

Due by July 13, 2001.

Exercise 2

Web Quiz 6

• Ch 3, pp. 81-89 & 176-192 sects. I-III, Related study questions, SAQ 4 and Problem 2.
• Be able to classify the feeds and know the general characteristics.  
• Be able to state why a feed is included in a livestock diet (e.g., corn grain is included because it is high in starch and therefore provides a highly digestible, economical source of energy (DE, ME, TDN, ect.) for the animal.
• Be able to look at a nutrient analysis of a feed and have a good idea of its classification (e.g., energy feed, protein supplement, forage, etc.)

Due by July 16, 2001.

Web Quiz 7

• Ch 3, pp. 192-229,  section IV-IX, Related study questions, SAQs 1, 3, 5, 6, 7 8, and 10.
• Be able to classify roughages (see section C on page 233).
• Describe the stage of maturity effects on nutritive quality of pasture (or hay).
• Identify some special problems associated with grazing livestock.
• Compare and contrast silage with hay.
• Discuss mineral and vitamin sources (potential problems or limitations of certain sources, stability in feed concerns...)
• Discuss the purpose of processing feeds (grinding, rolling, pelleting, roasting, extruding)
• Describe the types of mixers and the sequence of ingredient addition to batch mixers.

Due by July 20, 2001.

Web Quiz 8

• Chapter 4 problems 1-8 and extra problems listed on Chapter4 web page.  Also, a link to the solutions to problems 1-8 is available on the Chapte 4  web page.
• Work on these problems early in case you have questions. DO NOT wait to the last minute!
• You will need to learn how to these, because you will be doing more problems later.

Due by July 23, 2001
