Animal Husbandry MCQ Question and Answer | Agriculture MCQ Question

The most suitable temperature for the separation of cream by centrifugal cream separator is 40°C.
By regulating the cream discharge opening by adjusting the cream screw, we can maintain the desired fat % in the cream. The ideal temperature for separation is 35° - 45°C.
The purpose of the skimming process is to separate the raw milk into skim milk and cream. The product temperature should normally be kept to ensure optimal skimming efficiency.

Spore-forming bacteria Bacillus and Clostridium.
Spore-forming bacteria include Bacillus (aerobic) and Clostridium (anaerobic) species. The spores of these species are dormant bodies that carry all the genetic material as is found in the vegetative form but do not have an active metabolism.
These bacilli are ubiquitous, and because they form spores, they can survive in the environment for many years.

Ovum produces Fertilizin.
ovum is the female reproductive cell, or gamete, in most anisogamous organisms (organisms that reproduce sexually with a larger, female gamete and a smaller, male one).
A chemical substance called fertilizin attracts the male epitokes and stimulates the shedding of sperm. It is secreted by a mature egg also known as the ovum.

The buffalo is commonly known as an Asian animal.
The buffalo (Bubalus bubalis), also called the Asian water buffalo, is a large bovid originating in the Indian subcontinent and Southeast Asia.
The skin of the river buffalo is black, but some specimens may have dark, slate-coloured skin. Water availability for buffalo is important in hot climates since they need wallows, rivers, or splashing water to assist in thermoregulation.

Substance responsible for increased penetration of Lyssa virus is Hyaluronidase.
Hyaluronidase is an enzyme that breaks down a substance in the body called hyaluronic acid. Hyaluronic acid is found throughout the body in connective tissue, skin, and fluids in the joints and inside the eye.
Lyssavirus is a genus of RNA viruses in the family Rhabdoviridae that are enveloped, with bullet-shaped geometries. These virions are about 75 nm wide and 180 nm long. Lyssavirions have helical symmetry, so their infectious particles are approximately cylindrical. This is typical of plant-infecting viruses.

The characteristics of Streptococcus are it is Gram-positive cocci and is arranged in chains. It is Catalase - Ve.
Streptococci are nonmotile, non-spore forming, catalase-negative cocci that occur in pairs or chains. Older cultures may lose their Gram-positive character. Most streptococci are facultative anaerobes, and some are obligate (strict) anaerobes.

The milk production is maximum in India in UP.
India has the world's largest dairy herd with over 300 million bovines, producing over 187 million tonnes of milk. India is first among all countries in both production and consumption of milk.
UP is at the top in the country in milk production, having 16 percent of the country's dairy production. Today UP produces 319 lakh metric tonnes per annum (MTPA) milk and is top in the country.

Goat tissue vaccine (GTV) is used against Rinderpest.
Goat tissue virus vaccine is developed at IVRI, Izatnagar in 1927.
Rinderpest was an infectious viral disease of cattle, domestic buffalo. 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.

For fatty acid synthesis, Acetyl Co-A comes from mitochondria to cytoplasm as Citrate.
The biosynthesis of fatty acids is a multi-step process in the cytoplasm, mainly of the liver and fat cells.
Acetyl-CoA, a significant carbon input into the citric acid cycle, can be derived from glucose or fatty acids, however, a substantial portion of acetyl-CoA comes from glucose or more specifically, pyruvate. In the mitochondrial matrix, acetyl-CoA is condensed with oxaloacetate to form citrate through the action of citrate synthase in the tricarboxylic acid cycle.

Diluent for preservation of buffalo semen is Citric acid whey.
Citric acid is a superior diluent for the preservation and freezing of buffalo semen. Samples of the semen from each bull were placed in each diluent.
Citric acid plays a vital role in the liquefaction of seminal fluid and thus has an indirect effect on the motility of the sperm and the eventual fertility of the male.
