Animal Husbandry MCQ Question and Answer | Agriculture MCQ Question

Incubation period (days) in chicken (Gallus gallus) is 21.
Fertile chicken eggs hatch at the end of the incubation period, about 21 days.
Development of the chick starts only when incubation begins, so all chicks hatch within a day or two of each other, despite perhaps being laid over two weeks or so. Before hatching, the hen can hear the chicks peeping inside the eggs and will gently cluck to stimulate them to break out of their shells.

All India co-ordinated Research project on cattle was established in 1987.
The Central Institute for Research on Cattle (CIRC) formerly known as Project Directorate on Cattle (PDC) was established on 3^rd November 1987 at Military Farms School and Research Centre, Meerut by upgrading the status of All India Coordinated Research Project (AICRP) on Cattle.

Milk sugar lactose is made up of Glucose + Galactose.
Milk sugar is composed of glucose and galactose. Galactose is less suitable as an energy source than glucose. Thus, it has been a puzzle as to why mammals utilize galactose as a major component of milk sugar.
This is one of the types of sugar molecules that make up lactose, the main type of sugar in milk and all products that contain milk. Galactose is found in milk and all milk products such as cottage cheese, yogurt, ice cream, buttermilk and cheese.

A. Bovidae ⇔ Sheep, goat cattle, buffalo
The Bovidae comprise the biological family of cloven-hoofed, ruminant mammals that includes cattle, bison, buffalo, antelopes, and caprines. A member of this family is called a bovid.

B. Suidae ⇔ Swine
Suidae is a family of artiodactyl mammals which are commonly called pigs, hogs or swine. All suids, or swine, are native to the Old World, ranging from Asia to Europe and Africa.

C. Equidae ⇔ Horse
Equidae (sometimes known as the horse family) is the taxonomic family of horses and related animals, including the extant horses, asses, zebras, and many other species known only from fossils.

D. Cammelidae ⇔ Ass is not correctly matched.
Camelids are members of the biological family Camelidae, the only currently living family in the suborder Tylopoda. Camelids are even-toed ungulates classified in the order Cetartiodactyla, along with species like whales, pigs, deer, cattle and antelopes.

Umbilical hernia is most commonly seen in Cattle.
Umbilical hernias are the most common birth defect in calves. They occur when the umbilical ring fails to close after birth, allowing abdominal contents to protrude through the opening.
Umbilical hernias vary in severity from those that will spontaneously heal to those that will need surgical repair.

The egg trays are tilted in artificial incubation at 180°.
Artificial incubation involves removing eggs from incubating parents and using an incubator to hatch them.
An incubator is a device simulating avian incubation by keeping eggs warm at a particular temperature range and in the correct humidity with a turning mechanism to hatch them. It lets the fetus inside the egg grow without the mother needing to be present to provide the warmth.

Enzyme coagulated milk product is Cheese.
Coagulation is the push-off-the-cliff that turns milk into cheese. Liquid milk is converted into a solid mass. This solid mass is often called “curd”, “gel” or the “coagulum”. Coagulation can occur in a few different ways like enzyme action, acid addition, or acid/heat addition.
When pH levels drop in milk, it turns acidic and milk protein (casein and others) molecules attract one another to form "curdles" or lumps. These lumps then float on the surface of the solution. The lumps are formed faster at warmer temperatures.

Egg shell made up of CaCO₃.
Egg shell is made almost entirely of calcium carbonate (CaCO₃) crystals. It is a semipermeable membrane, which means that air and moisture can pass through its pores.
The shell also has a thin outermost coating called the bloom or cuticle that helps keep out bacteria and dust.

a. Mastitis is a bacterial disease.
Mastitis is an inflammation of breast tissue that sometimes involves an infection. The inflammation results in breast pain, swelling, warmth and redness.

b. Plague is caused by bacteria.
Plague is an infectious disease caused by the bacterium Yersinia pestis. Symptoms include fever, weakness and headache.

c. Ringworm is caused by Fungi.
Ringworm is a common infection of the skin and nails that are caused by fungus. The infection is called “ringworm” because it can cause an itchy, red, circular rash. Ringworm is also called “tinea” or “dermatophytosis.”

d. Milk fever is caused by Calcium deficiency.
Milk fever is a metabolic disorder caused by insufficient calcium, commonly occurring around calving. Milk fever, or hypocalcaemia, is when the dairy cow has lowered levels of blood calcium.

The origin of Tharparkar is Tharparkar (Hyderabad).
Tharparkar is a breed of cattle originating in Tharparkar District in Sindh province in present day Pakistan and also found in neighbouring nations of India.
It is a dual purpose breed known for both its milking and draught potential. The cattle are of medium to large build and have white to gray skin.
