31
Q

Types of Digestion

A 
Chewing
Chemical Digestion (HCl is released into the stomach and bile is secreted in the small intestine)
32
Q

Break down food particles into their molecular constituents so that they are small enough to be absorbed across the intestinal wall into the blood and lymphatic system and eventually into the cells for body funciton.

33
Q

Function to break down food particles via microbial digestion in ruminant animals

34
Q

Monogastric

A

Animals who have one section to their stomach and a functioning cecum

35
Q

Sections of the Small Intestine

A

duodenum (where bile is secreted), jejunum and ileum

36
Q

Large Intestine Function

A

Resorb water and provide storage for undigested food

37
Q

40-50 gallon capacity section of the stomach known for storage, physical mixing of ruminal digesta and acting as a fermentation chamber with the help of bacteria, protozoa and fungi

38
Q

honeycomb pouch of the stomach that works to regurgitate food

39
Q

Stockman’s Bible (folds) section of the stomach that resorbs water from the rumen, allowing digesta to exit as a paste

40
Q

“true stomach” releasing MCl and pepsin as gastric juices similar to stomachs on non-ruminant animals

41
Q

Three primary factors that affect nutrient requirements within a given species includes:

A

weight of the animal, stage of production and level of performance

42
Q

Nutrient requirements peak at what stage of production?

A

two months postpartum (then they go down until the third trimester of the following pregnancy)

43
Q

chemical procedure that breaks down and ascertain nutrient value

A

proximate analysis

44
Q

Organic components (carbon, hydrogen, oxygen and nitrogen) that serve as energy and are available in a given feed sample

A

Total Digestible Nutrients (TDN)

45
Q

Carbohydrates (including cellulose) are associated with ____

A

Crude Fiber (CF): a measure of of the lowly digestible material in a feedstuff including cellulose, hemicellulose and lignin

46
Q

As forages grow and mature, crude fiber becomes a _______ percentage of the plant

A

larger (reducing energy and protein content

47
Q

Percentage of nutrient or weight of feed contained only in the dry matter fraction - moisture free

A

Dry matter (DM)

48

Protein supplements typically have more than ____ CP

60
Q

plant (soybean, cottonseed, linseed, sunflower and corn gluten meal), animal (blood meal, spray-dried plasma, meat and bone meal, and dried whey) or non-protein nitrogen sources (urea and ammonia).

A

Protein sources

61
Q

True or False: and food identified as a “meal” is typically considered a protein supplement

62

Minerals are most often added to feed rations through

64
Q

Feed ration can be discovered through use of

A

The Pearson Square
