Animal Husbandry MCQ Question and Answer | Agriculture MCQ Question

Conception rate in A.I. is 58% - 75%.
The genetics underlying the physiological processes responsible for CCR, the proportion of cows able to conceive and maintain a pregnancy at each breeding, are not well characterized.
Factors such as body condition loss, heat detection errors, and less than optimum semen handling and placement, make it readily apparent why many herds have conception rates.

Cow milk is not complete food because it is deficient in iron content.
Excessive consumption of cow's milk can lead to iron deficiency anemia caused by dietary imbalance, decreased consumption of solids, and increased consumption of an iron-deficient milk diet; Cow's milk contains predominantly non-heme iron, which is much less digestible than heme iron.

Largest organ of the body of poultry is Gizzard.
This specialized stomach constructed of thick muscular walls is used for grinding up food, often aided by particles of stone or grit. In certain insects and molluscs, the gizzard features chitinous plates or teeth.
The gizzard can grind the food with previously swallowed grit and pass it back to the true stomach, and vice versa.

In species with estrous cycles, females are generally only sexually active during the estrus phase of their cycle. This is also referred to as being "in heat".
a. The heat period of Swine is 1 - 5 days.
b. The heat period of Goat is 1 - 3 h.
c. The heat period of Cow is 18 - 24 h.
d. The heat period of Sheep is 24 - 48 h.

Zoonotic diseases are perpetuated in nature by a single vertebrate species is by Direct zoonosis.
Zoonosis is an infectious disease that has jumped from non-human animals to humans. Zoonotic pathogens may be bacterial, viral or parasitic, or may involve unconventional agents and can spread to humans through direct contact or food, water or the environment.
Direct zoonosis may be perpetuated in nature by a single vertebrate species, such as dogs or foxes for rabies or cattle, small ruminants or swine for brucellosis.

Synchronisation of heat (controlling heat) is desired in Sheep.
It is the process of targeting female mammals to come to heat within a short time frame. This is achieved through the use of one or more hormones.
Methods to improve our ability to synchronize the reproductive process and result in 'timed insemination' without the detection of heat have been developed.

In Johne's disease, corrugation is not the feature in Sheep and Horses.
Johne's disease is an infectious wasting condition of cattle and other ruminants caused by Mycobacterium avium subspecies paratuberculosis, commonly known as Map. It is closely related to the organism that causes tuberculosis.
Johne's disease (paratuberculosis) is a chronic debilitating disease that affects the intestines of all ruminants, including cattle, sheep and goats. It is characterized by progressive emaciation, chronic diarrhea, and a thickened and corrugated wall of the intestines.

The ligament is primarily responsible for the udder 'breaking down' in Median suspensory.
The median suspensory ligament is the most important part of the suspensory system in cows. It is composed of two adjacent heavy yellow elastic sheets of tissue that arise from the abdominal wall and that attach to the medial flat surfaces of the two udder halves.

The largest cattle fair is held in Harihar area Sonpur (Bihar).
Sonepur Cattle Fair is held on Kartik Poornima (the full moon day) over November and December in Sonepur, Bihar, on the confluence of river Ganges (Gandak). It is also known as Harihar Kshetra Mela.
The Sonepur Cattle Fair was used to attract traders from places as far away as Tamil Nadu and Delhi. In 2018, the Fair started on the 21^st of November and continued until the 22^nd of December.

The best age for dehorning is 1 week.
Dehorning is the process of removing the horns of livestock. Cattle, sheep, and goats are sometimes dehorned for economic and safety reasons.
It can be performed on older animals and is normally performed with local anesthesia by a veterinarian or a trained professional. Removal of larger horns is usually performed during spring and autumn to avoid the fly season.
