Glucagon is a peptide hormone secreted by the alpha-cells in the pancreas. As is known, the function of glucagon in the liver include ________________________.(A) decreasing glycogen breakdown(B) increasing gluconeogenesis (C) decreasing fatty acid breakdown(D) decreasing the synthesis of ketone bodies (E) all B, C, and D above

After a complete oxidation outside of an animal body, 2 grams of fat can release approximately 8 to 8.5 kilocalories of gross energy.

If two feed ingredients have same amounts of Metabolizable Energy (ME), one of the following statements will correctly describe the relationship between these two ingredients. (A) The Net Energy for maintenance (NEm) and Net Energy for growth (NEp) will be the same between these two ingredients.(B) The Net Energy for maintenance (NEm) and Net Energy for growth (NEp) would be the same between these two ingredients only if both were fed to the pig. (C) An animal will get more energy for maintenance than for growth from these two ingredients.(D) An animal will get less energy for maintenance than for growth from these two ingredients.(E) Whether an animal will get more energy for NEm or more energy for NEp from one of the feed ingredients would depend on the species of animal that we are talking about.

As long as we provide enough dietary gross energy for lay hens, these chickens will be able to use all the metabolizable energy to produce eggs.  

The clinical symptoms of human vitamin B2 deficiency include cheilosis, angular cheilitis, stomatitis, and glossitis.

Please describe the relationships between different energy systems used in animal nutrition study and practice?  [Hint: Remember the energy systems include GE, ME, etc. However, you need to describe them one by one and we should be able to see their relationships. You need to describe at least 2 types of NE.]

If you provide sufficient nutrients to a pig or a horse, you can definitely maximize the body weight gain and the feed efficiency at the same time.

Grass tetany of cattle is a problem caused by the magnesium (Mg) deficiency in the succulent, immature grass that the cattle graze on.

Chloride is a very important cation in animal body, which is required for the absorption of many other nutrients.

Insulin is a peptide hormone secreted by the beta-cells in the pancreas. As is known, the function of insulin in the body include ________________________.(A) increasing glycogen breakdown in the liver(B) decreasing gluconeogenesis in the liver(C) decreasing fatty acid breakdown(D) increasing the synthesis of ketone bodies (E) all B, C, and D above
