[#366] Most common method used for animal breeding is
Correct Answer
(D) Out breeding
Explanation
Solution: Most common method used for animal breeding is Out breeding. Out-crossing or out-breeding is the technique of crossing between different breeds. It is a useful technique in animal breeding. The outcrossing breeder intends to remove the traits by using new blood. This is the practice of introducing distantly related genetic material into a breeding line, thereby increasing genetic diversity.
[#367] The time temperature combination in plate pasteurization is
Correct Answer
(B) 72°C for 15 seconds
Explanation
Solution: The time temperature combination in plate pasteurization is 72°C for 15 seconds. Most liquid products were heat treated in a continuous system where heat can be applied using a plate heat exchanger or the direct or indirect use of hot water and steam. The minimum pasteurization conditions are those having bactericidal effects equivalent to heating every particle of the milk to 72°C for 15 seconds. Modern HTST pasteurization processes must be designed with flow-rate restriction as well as divert valves which ensure that the milk is heated evenly and that no part of the milk is subject to a shorter time or a lower temperature.
[#368] Jersy is native of
Correct Answer
(B) England
Explanation
Solution: Jersy is native of England. The Jersey is a British breed of small dairy cattle from Jersey, in the British Channel Islands. It descended from cattle stock brought over from the nearby Norman mainland, and was first recorded as a separate breed around 1700. Jersey adapts well to various climates and environments, and unlike many breeds originating in temperate climates, these cows can tolerate heat very well. The milk is high in butterfat and has a characteristic yellowish tinge.
[#369] Humpless cattle belong to group
Correct Answer
(A) Bos tauras
Explanation
Solution: Humpless cattle belong to the group Bos taurus. Bos taurus includes European-origin cattle breeds that are characterized by the absence of a hump. Bos indicus: Refers to zebu cattle, which are humped and are primarily found in tropical regions. Bos bubalis: Includes domesticated water buffalo, which are unrelated to humpless cattle. Bos arni: Refers to wild water buffalo and is also unrelated to humpless cattle. Thus, the correct choice is Option A: Bos taurus, as humpless cattle fall under this group.
[#370] Body temperature of cow is
Correct Answer
(C) 101°F
Explanation
Solution: Body temperature of cow is 101°F. Cows are warm-blooded and need to maintain a constant core body temperature. Normal rectal temperature for a cow is around 38°C (101°F).
