    The dressing percentage for beef range is which of the following?

    • 55%-67%

    • 45%-58%

    • 65%-77%

    Correct Answer
    A. 55%-67%
    Explanation
    The dressing percentage for beef refers to the percentage of the live weight of the animal that remains after it has been slaughtered and dressed (removal of head, hide, internal organs, and feet). The correct answer is 55%-67%, which means that on average, beef carcasses will retain 55%-67% of their live weight after dressing.

    Rate this question:

  • 3. 

    Last rib fat in swine is factored into the USDA Grade calculation.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    The statement is true. In the USDA Grade calculation for swine, the last rib fat is taken into consideration. This means that the amount of fat present in the last rib of the swine is considered as a factor in determining the overall grade of the meat. This is done to assess the quality and marbling of the meat, as the amount of fat can affect the tenderness, juiciness, and flavor of the meat.

    Rate this question:

  • 4. 

    The preliminary yield grade is determined by the thickness of external fat over the ribeye. 

    • True

    • False

    Correct Answer
    A. True
    Explanation
    The preliminary yield grade is determined by the thickness of external fat over the ribeye. This means that the amount of fat present on the ribeye plays a role in determining the yield grade. A higher amount of external fat indicates a lower yield grade, as more fat means less meat available for consumption. Therefore, this statement is true.

    Rate this question:

  • 5. 

    Gut fill affects the dressing percentage of beef, sheep and swine.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    Gut fill refers to the contents present in the digestive system of animals, such as food, water, and other materials. The weight of the gut fill can significantly impact the dressing percentage, which is the proportion of the animal's live weight that remains after it has been slaughtered and dressed. As gut fill can vary in weight, it can affect the overall dressing percentage of beef, sheep, and swine. Therefore, the statement is true.

    Rate this question:

  • 6. 

    What are live lambs evaluated by?

    • Weight

    • Dressing percentage

    • Ribeye Area

    • Yield Grade

    • All the above

    Correct Answer
    A. All the above
    Explanation
    Live lambs are evaluated by their weight, dressing percentage, ribeye area, and yield grade. These factors are important in determining the quality and value of the lamb. Weight is a basic measure of the animal's size and can indicate its potential for meat production. Dressing percentage is the ratio of the carcass weight to the live weight, which provides information about the efficiency of the animal in converting feed into meat. Ribeye area is a measurement of the size of the eye muscle in the carcass, which is a major determinant of meat yield. Yield grade evaluates the amount of usable meat in the carcass, taking into account factors such as fat thickness and muscle content. Therefore, all of these factors are considered when evaluating live lambs.

    KpH stands for what?

    • Kennedy, Pelvic and Heat

    • Kidney, Pulse and Heart

    • Kelcie, Pelvic and Heart

    • Kidney, Pelvic and Heart

    Correct Answer
    A. Kidney, Pelvic and Heart
    Explanation
    KPH stands for Kidney, Pelvic, and Heart. This is the correct answer because KPH is an acronym that represents these three specific body parts. The other options, Kennedy, Pelvic, and Heat, Kelcie, Pelvic, and Heart, and Kidney, Pulse, and Heart, do not accurately represent the intended meaning of KPH.

    Rate this question:

  • 8. 

    Gut fill affects the dressing percentage of beef, sheep and swine.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    The statement is true because the gut fill refers to the contents in the digestive system of animals, such as food and water. When animals are weighed for dressing percentage, the weight of the gut fill is subtracted from the total weight to determine the weight of the carcass. Therefore, a larger gut fill would result in a lower dressing percentage, as it contributes to a higher overall weight. Hence, the gut fill does affect the dressing percentage of beef, sheep, and swine.

    Rate this question:

  • 9. 

    There are at least how many different fat  indicators when evaluating market beef?

    • 3

    • 4

    • 5

    • 6

    • We didn't evaluate beef

    Correct Answer
    A. 5
    Explanation
    When evaluating market beef, there are at least five different fat indicators. This suggests that there are multiple factors to consider when assessing the quality and fat content of beef in the market.

    The yield grade is determined by what?  Check all that apply.

    • Preliminary yield grade

    • Required ribeye area

    • Actual ribeye area

    • KPH

    • Chine bone

    Correct Answer(s)
    A. Preliminary yield grade
    A. Required ribeye area
    A. Actual ribeye area
    A. KPH
    Explanation
    The yield grade is determined by several factors, including the preliminary yield grade, required ribeye area, actual ribeye area, and KPH. The preliminary yield grade is an initial assessment of the meat's yield potential. The required ribeye area is a measurement that determines the amount of usable meat from the ribeye muscle. The actual ribeye area is the measured size of the ribeye muscle. KPH refers to the amount of kidney, pelvic, and heart fat, which can affect the overall yield. Therefore, all of these factors play a role in determining the yield grade.

    Dressing percentage is what?

    • Live weight divided by the carcass weight

    • Carcass weight divided by the live weight

    • The yield grade divided by the quality grade

    • It is a pure guess

    Correct Answer
    A. Carcass weight divided by the live weight
    Explanation
    Dressing percentage is a measurement used in the meat industry to determine the amount of usable meat on an animal carcass. It is calculated by dividing the carcass weight (the weight of the animal after it has been slaughtered and dressed) by the live weight (the weight of the animal when it was alive). This calculation helps in assessing the efficiency of meat production and can vary depending on factors such as breed, age, and fat content of the animal.

    Quality grading is based on what two factors?  Check all that apply.

    • Physiological maturity

    • Ribeye area

    • Fat cover

    • Marbling

    Correct Answer(s)
    A. Physiological maturity
    A. Marbling
    Explanation
    Quality grading in meat is determined by various factors, including physiological maturity and marbling. Physiological maturity refers to the age at which the animal was harvested, as this affects the tenderness and flavor of the meat. Marbling, on the other hand, refers to the presence of intramuscular fat within the meat, which enhances its juiciness and flavor. Therefore, these two factors play a significant role in determining the quality grade of meat.

    The preliminary yield grade is determined by the thickness of external fat over the ribeye. 

    • True

    • False

    Correct Answer
    A. True
    Explanation
    The preliminary yield grade is determined by the thickness of external fat over the ribeye. This means that the amount of fat present on the ribeye plays a role in determining the yield grade. If there is a higher amount of external fat, it indicates that there will be a higher yield of usable meat from the carcass. Therefore, the statement is true.

    Rate this question:

    The yield grade is determined by what?  Check all that apply.

    • Preliminary yield grade

    • Required ribeye area

    • Actual ribeye area

    • KPH

    • Chine bone

    Correct Answer(s)
    A. Preliminary yield grade
    A. Required ribeye area
    A. Actual ribeye area
    A. KPH
    Explanation
    The yield grade is determined by several factors, including the preliminary yield grade, required ribeye area, actual ribeye area, and KPH. The preliminary yield grade is an initial assessment of the meat's yield potential. The required ribeye area refers to the minimum size of the ribeye muscle, which is an indicator of the meat's quality and yield. The actual ribeye area measures the size of the ribeye muscle in the carcass. KPH stands for kidney, pelvic, and heart fat, which is another factor used to determine the yield grade. The chine bone, however, is not a factor in determining the yield grade.

    Correct Answer(s)
    A. Physiological maturity
    A. Marbling
    Explanation
    Quality grading in the context of beef is based on two factors: physiological maturity and marbling. Physiological maturity refers to the age at which the animal was harvested, as it affects the tenderness and flavor of the meat. Marbling, on the other hand, refers to the intramuscular fat that is distributed throughout the meat, which adds flavor, juiciness, and tenderness. Ribeye area and fat cover are not directly related to quality grading, although they can be indicators of certain characteristics such as size and fat content.

    Which of the following is not a muscle indicator in beef?

    • Forearm

    • Loin

    • Last Rib

    • Quarter

    • Rump

    Correct Answer
    A. Last Rib
    Explanation
    The last rib is not a muscle indicator in beef because it refers to a specific rib bone and not a muscle. Muscle indicators in beef typically refer to specific cuts or sections of meat that are commonly used in culinary preparations. The forearm, loin, quarter, and rump are all examples of muscle indicators in beef as they refer to specific muscle groups or sections of the animal's body.

    Last rib fat in swine is factored into the USDA Grade calculation.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    The statement is true because the last rib fat in swine is indeed factored into the USDA Grade calculation. This means that the amount of fat present in the last rib of a pig is taken into account when determining the quality grade of the meat. The USDA Grade is a system used to classify the quality of meat based on various factors such as marbling, tenderness, and juiciness. Therefore, the amount of fat in the last rib plays a role in determining the overall grade of the swine meat.

    Yield grade 1 is the lowest in cutability.

    • True

    • False

    Correct Answer
    A. False
    Explanation
    The statement "Yield grade 1 is the lowest in cutability" is false. Yield grade refers to the amount of lean meat that can be obtained from a carcass, while cutability refers to the ease of cutting and processing the meat. A higher yield grade indicates a higher percentage of lean meat, which means it is easier to cut and process, making it higher in cutability. Therefore, Yield grade 1 is actually the highest in cutability, not the lowest.
