The ruminant digestive system is made up of the following
- A.
Reticulum, abomasum, omasum and rumen
- B.
Crop, large intestine and rumen
- C.
Rumen, reticulum, crop and proventriculus
Correct Answer
A. Reticulum, abomasum, omasum and rumenExplanation
The correct answer is reticulum, abomasum, omasum, and rumen. These four components make up the ruminant digestive system. The reticulum is responsible for the initial breakdown of food, while the rumen is the main fermentation chamber where bacteria and other microorganisms break down cellulose. The omasum absorbs water and nutrients, and the abomasum acts as the true stomach where further digestion occurs. The other options listed do not include all four components of the ruminant digestive system.Rate this question:

The omasum is the stomach of a ruminant that secretes hydrochloric acid to digest food
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
The omasum is not the stomach of a ruminant that secretes hydrochloric acid to digest food. The omasum is actually the third compartment of a ruminant's stomach, and its main function is to absorb water, electrolytes, and some nutrients from the partially digested food before it moves on to the abomasum for further digestion. The abomasum is the true stomach of a ruminant where hydrochloric acid is secreted to break down proteins and other nutrients. Therefore, the correct answer is False.Rate this question:

Methane and carbon dioxide is produced
- A.
By a ruminant as a by product of protein digestion
- B.
By a monogastric as a byproduct of microbial protein
- C.
By a ruminant as a byproduct of carbohydrate digestion
Correct Answer
C. By a ruminant as a byproduct of carbohydrate digestionExplanation
Ruminants have a unique digestive system that allows them to break down and ferment plant material in their rumen, a specialized stomach chamber. During this fermentation process, carbohydrates are broken down by microbes into volatile fatty acids, which are then absorbed by the ruminant as a source of energy. However, not all of the carbohydrates can be fully digested, and some are converted into methane gas by methanogenic microbes. Therefore, methane is produced by a ruminant as a byproduct of carbohydrate digestion. Carbon dioxide is also produced during this process as a byproduct of microbial metabolism.Rate this question:

Ruminants are able to use urea to produce amino acids and protein
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Ruminants, such as cows and sheep, have a unique digestive system that allows them to break down and utilize urea, a waste product of protein metabolism, as a source of nitrogen. Urea is converted by specialized bacteria in the rumen into ammonia, which is then used by the ruminant's body to produce amino acids and ultimately protein. This adaptation enables ruminants to efficiently utilize low-quality forages, which often contain high levels of fiber and low levels of protein. Therefore, the statement that ruminants are able to use urea to produce amino acids and protein is true.Rate this question:

The feed conversion rate is defined as follows:
- A.
The weight of feed eaten divided by the weight gained by animal
- B.
The weight gained by the animal divided by the weight of feed eaten
- C.
The weight of the animal divided by the average weight of the herd
Correct Answer
A. The weight of feed eaten divided by the weight gained by animalExplanation
The correct answer is "the weight of feed eaten divided by the weight gained by animal." This is because the feed conversion rate is a measure of how efficiently an animal converts the feed it consumes into weight gain. By dividing the weight of feed eaten by the weight gained by the animal, we can determine how much feed is required for a certain amount of weight gain. The lower the feed conversion rate, the more efficient the animal is in converting feed into weight gain.Rate this question:
