Animal Husbandry MCQ Question and Answer | Agriculture MCQ Question

Ruminant's stomach is divided into 4 parts.
Ruminant stomachs have four compartments: the rumen, the reticulum, the omasum and the abomasum.
Rumen microbes ferment feed and produce volatile fatty acids, which is the cow's main energy source. Rumen microbes also produce B vitamins, vitamin K and amino acids.

The average per year egg production of Leghorn fowl is 200 - 250.
The Leghorn is a breed of chicken originating in Tuscany, in central Italy. Birds were first exported to North America in 1828 from the Tuscan port city of Livorno, on the western coast of Italy.
Leghorns are good layers of white eggs, laying an average of 200 - 250 per year and sometimes reaching 300, with a weight of at least 55 g. White Leghorns have been used to create highly productive egg-laying hybrids for commercial and industrial operations.

Magra, Nali and Chokla breeds provide carpet wool.
The Magra sheep breed also known as Bikaneri, provides the 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 - 3 kg.
Chokla is fine carpet wool Indian sheep and reared basically for its wool quality and suitability for migration. Chokla grows the finest carpet wool.

Hormone secreted from pancreas and lower blood sugar levels are Insulin.
Insulin is a peptide hormone secreted by the β cells of the pancreatic islets of Langerhans and maintains normal blood glucose levels by facilitating cellular glucose uptake, regulating carbohydrate, lipid and protein metabolism and promoting cell division and growth through its mitogenic effects.

The temperature for LTLT pasteurization is 61° - 63°C.
Pasteurization is a process of food preservation in which packaged and non-packaged foods are treated with mild heat, usually to less than 100°C (212°F), to eliminate pathogens and extend shelf life.
The LTST (Low Temperature Long Time) method depends on a mechanism in which low heat and low pressure are utilized to pasteurize a fluid milk product. In this process, milk is dispersed in the form of droplets into a process chamber and heated for 0.02 s at or below pasteurization temperatures (61° - 63°C).

Casein forms 80 - 83% of total milk proteins.
Casein is a family of related phosphoproteins (αS1, aS2, β, κ) that are commonly found in mammalian milk, comprising about 80% of the proteins in cow's milk and between 20% and 60% of the proteins in human milk. Sheep and Cow milk have a higher casein content than other types of milk with human milk having a particularly low casein content.

The animal resistant to Atherosclerosis is Cattle.
Atherosclerosis is a pattern of the disease arteriosclerosis in which the wall of the artery develops abnormalities, called lesions. These lesions may lead to narrowing due to the buildup of atheromatous plaque.
Atherosclerosis affects only herbivores except for cattle. Dogs, cats, tigers, and lions can be saturated with fat and cholesterol.

Rumen degradable protein content is highest for Groundnut cake.
Groundnut cake is a by product obtained after the extraction of oil. The cake contains 45 - 60% protein, 22 - 30% carbohydrate, 3.8 - 7.5% crude fibre and 4 - 6% minerals.
A higher ruminal degradability of protein has been reported for groundnut cake at 0.46 and 0.42.

Equine plague is also called African Horse sickness.
African horse sickness (AHS) is a highly infectious and deadly disease caused by African horse sickness virus. It commonly affects horses, mules and donkeys.
This disease can be caused by any of the nine serotypes of this virus. AHS is not directly contagious, but is known to be spread by insect vectors.

Expulsion of foetus in cow is known as Calving.
Calving is the process of giving birth to a calf. A calf is a young domestic cow or bull. Calves are reared to become adult cattle or are slaughtered for their meat, called veal, and hide. Calves may be produced by natural means, or by artificial breeding using artificial insemination or embryo transfer.
Dairy cows can only produce milk after having calved, and dairy cows need to produce one calf each year to remain in production.
