Animal Husbandry MCQ Question and Answer | Agriculture MCQ Question

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.

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.

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.

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).

Wound that does not heal is known as Ulcer.
A chronic wound is a wound that does not heal in an orderly set of stages and in a predictable amount of time the way most wounds do; wounds that do not heal within three months are often considered chronic.
An ulcer is a wound that does not heal quickly. It is an open wound or sore that will not heal or keeps returning.

Yellow fever is transmitted by Ades aegypti.
Yellow fever is a viral disease of typically short duration. In most cases, symptoms include fever, chills, loss of appetite, nausea, muscle pains particularly in the back and headaches.
The disease is caused by the yellow fever virus and is spread by the bite of an infected mosquito, primarily by Aedes aegypti, a type of mosquito found throughout the tropics and subtropics.

Amino acid precursor of lignin is Phenylalanine.
Lignin is a class of complex organic polymers that form key structural materials in the support tissues of most plants.
The biosynthesis begins in the cytosol with the synthesis of glycosylated monolignols from the amino acid phenylalanine. The reactions are shared with the phenylpropanoid pathway.

Chemical used for dehorning is Caustic potash.
Removing horns by disbudding or dehorning is a common management practice to reduce the risk of injury and bruising to other cattle.
Caustic potash or caustic soda is the common chemical used for dehorning. These are available in the form of paste or solution. Clip the hair around the horn buds and surrounding area, and a ring of Vaseline to protect the eyes against chemicals.

Crude fibre in roughages is > 18%.
Crude fibre is the insoluble residue of acid hydrolysis followed by an alkaline one. This residue contains true cellulose and insoluble lignin. It is also used to assess hair, hoof, or feather residues in animal by-products.
The National Research Council classifies a roughage as a feedstuff with a minimum crude fiber content of 18% and a maximum content of total digestible nutrients (TDN) of 70%. Roughages provide a range of nutrients to animals.
