[#576] The fat content of plain ice cream is
Correct Answer
(B) 10%
Explanation
Solution: The fat content of plain ice cream is 10%. The standard of identity of ice cream requires a minimum milk fat content of 10%. Fat reduction is a means of eliminating calories from food because fat provides more energy per gram than other macronutrients. Reduced fat ice cream is approximately 7% fat. Low-fat ice cream is no more than 3% milk fat.
[#577] Rinderpest is caused by
Correct Answer
(B) Virus
Explanation
Solution: Rinderpest is caused by Viruses. Rinderpest virus (RPV), a member of the genus Morbillivirus, is closely related to the measles and canine distemper viruses. The virus is particularly fragile and is quickly inactivated by heat, desiccation and sunlight. It was an infectious viral disease of cattle, domestic buffalo, and many other species of even-toed ungulates, including gaurs, buffaloes, large antelope, deer, giraffes, wildebeests and warthogs.
[#578] The most suitable method of milking is
Correct Answer
(A) Fisting (Full hand) method
Explanation
Solution: The most suitable method of milking is Fisting (Full hand) method. Milking is done either by stripping or by full hand method. Grasping the teat with all the five fingers and pressing it against the palm does fisting or full hand milking. The teat is compressed and relaxed alternatively in quick succession, thus the method removes milk much quicker than stripping as there is no loss of time in changing the position of the hand. Further full hand method is superior to stripping as it stimulates the natural suckling process by calf and the method exerts equal pressure on the large teats of cows and buffaloes.
[#579] The method of sex determination in birds is
Correct Answer
(C) ZX
Explanation
Solution: The method of sex determination in birds is ZX. The sex chromosomes in birds are designated Z and W, and the male is the homomorphic sex (ZZ) and the female is heteromorphic (ZW). In most avian species the Z chromosome is large, usually the fourth or fifth largest, and it contains almost all the known sex-linked genes.
[#580] Digestible crude protein (DCP) in legume fodder is
Correct Answer
(C) 2.5 - 3%
Explanation
Solution: Digestible crude protein (DCP) in legume fodder is 2.5 - 3%. The digestible crude protein (DCP) content of a feed, multiply by the digestibility coefficient of the crude protein with the crude protein content of the feedstuff. It is the amount of crude protein absorbed by the animal (crude protein minus the protein lost in feces).
