Animal Husbandry MCQ Question and Answer | Agriculture MCQ Question

Wallowing is a common behaviour of Buffalo.
Wallowing in animals is comfort behaviour during which an animal rolls about or lies in mud, water, or snow.
To thermoregulate, they rely on wallowing in water or mud to cool the body. These animals lack functional sweat glands and are almost incapable of panting.

FMD (foot and mouth disease) is caused by viruses.
Foot-and-mouth disease (FMD) or hoof-and-mouth disease (HMD) is an infectious and sometimes fatal viral disease that affects cloven-hoofed animals, including domestic and wild bovids.
The virus responsible for FMD is an aphthovirus, foot-and-mouth disease virus. Infection occurs when the virus particle is taken into a cell of the host. The disease is characterized by a high fever that declines rapidly after two to three days, blisters inside the mouth that lead to excessive secretion of stringy or foamy saliva and drooling, and blisters on the feet that may rupture and cause lameness.

Disease caused by Clostridium septicum is Braxy.
Braxy is an infectious disease that causes sudden death in sheep. It is caused by the bacterium Clostridium septicum.
Braxy generally occurs in winter, when sheep eat frosted root crops or frosted grass. The frozen feed damages the mucosa (lining) of the abomasum, allowing C. septicum to enter, causing abomasitis and fatal bacteremia.

The biological value of buffalo meat is 65%.
Biological value measures protein quality by calculating the nitrogen used for tissue formation divided by the nitrogen absorbed from food. This product is multiplied by 100 and expressed as a percentage of nitrogen utilized.
Meat is a significant source of protein, which is of high biological value. Within developed nations, meat provides around 60% of protein intake compared with only 15% in poorer nations. The protein content of different meats and cuts varies inversely with fat content.

Circling disease in cattle is caused by Listeria monocytogenes.
Listeriosis is an infectious but not contagious disease caused by the bacterium Listeria monocytogenes, far more common in domestics animals, especially ruminants, than in human beings.
It is a localized ascending asymmetric infection of the brain stem of ruminants by Listeria monocytogenes.

Best pH for semen preservation is 6.8.
A high or low semen pH can kill sperm or affect how well they can move or can penetrate an egg. White blood cell count. A high number of white blood cells and bacteria in the semen may be a sign of infection.
Sperm banking is the process of collecting, freezing and storing sperm. It's also called sperm freezing or sperm cryopreservation.

Egg production starts in poultry at the age of $$5\frac{1}{2}$$ months.
Birds usually start to lay at around five months (20 - 21 weeks) of age and continue to lay for 12 months (52 weeks) on average, laying fewer eggs as they near the moulting period.
During ideal day length (14 - 16 hours of light) and with adequate nutrition, housing, and management, hens (depending on breed) should begin producing eggs when they are 18 - 22 weeks old.

Magra, Nali and Chokla breed carpet wool.
The Magra sheep breed also known as Bikaneri provides lustrous carpet wool. Magra sheep flocks have extremely white and lustrous fleece.
Nali breed is used for wool and meat production and is not used for milk production. The average wool yield is 1.5 - 3kg.
Chokla is fine carpet wool Indian sheep and is reared basically for its wool quality and suitability for migration. Chokla grows the finest carpet wool.

The oestrus cycle of goat is 21 days.
In goats, the length of the estrous cycle is an average of 21 days but can vary between 18 and 24 days.
Average duration of estrus is 36 hours. However, the oestrus stage may last 12 to 48 hours, depending on breeds and environmental factors, such as the presence of a buck and the season.
This cycle is characterized by four periods that are estrus, metestrus, diestrus, and proestrus. The oestrus or heat phase lasts 12 - 48 hours.

Dentation is best for age determination of animals.
Cattle dentition is generally used as an indicator of age when actual birthdates are not available. Eruption times and wear of the teeth are the major factors used to estimate bovine age.
The central pair of temporary incisors are replaced by permanent ones which attains full growth by 2 years. The fourth permanent incisors erupt after 30 months. The second pair of incisors is fully developed at 3 years.
