Animal Husbandry MCQ Question and Answer | Agriculture MCQ Question

Failure of the retractor penis muscles to relax and allow the penis to extend from the sheath is known as Impotentia coeundi.
The retractor penis muscle occurs in marsupials and carnivorans, but it is absent in humans. A stag's penis forms an S-shaped curve when it is not erect and is retracted into its preputial sheath by the retractor penis muscle.
Impotentia coeundi is characterized by normal sexual desire and normal ability to copulate but the fertility is either subnormal or absent.

Diamond skin disease is primarily a disease of Sow.
Erysipelas, also called diamond-skin disease, can cause issues at all stages of pork production, causing acute septicemia, and reproductive issues such as sudden abortions or even lameness.
This disease is zoonotic and mainly an occupational hazard since the transmission occurs through cuts or skin punctures.

A. Goat ⇔ Kidding
Kidding, the act of the birthing process in goats is the culmination of the breeding process in goats. Goat kids are the primary source of income in commercial goat breeding herds.
B. Horse ⇔ Foaling
Foaling, also referred to as parturition, is the process of a mare giving birth to a foal. Foaling occurs approximately 338 to 345 days from the last breeding date, however, this period can range from 320 to 365 days or more.
C. Sheep ⇔ Lambing
Lambing is the time in the spring when female sheep give birth to lambs. Lambing is the climax of the sheep farmer's year, the lambing season.
D. Buffalo ⇔ Farrowing is not correctly matched.
Buffalo breed throughout the year, conceive at 250 - 275 kg body weight, calve for the first time at 3 - 5 years following a gestation period of 305 - 320 days, and produce two calves every 3 years.

Erythritol sugar plays important role in the pathogenesis of Brucella sp.
Erythritol is a four-carbon sugar preferentially utilized by Brucella spp. The presence of erythritol in the placentas of goats, cows, and pigs has been used to explain the localization of Brucella to these sites and the subsequent accumulation of large amounts of bacteria, eventually leading to abortion.

A. Diene's stain - Mycoplasma
It involves the use of Diene's stain, which is widely used to detect animal mycoplasmas and plant spiroplasmas in culture. Diene's stain was prepared by dissolving 2.5 g of methylene blue, 1.25 g of azure II, 10.0 g of maltose, and 0.25 g of sodium carbonate in 100 ml distilled water.

B. Fontana stain - Spirochaetes
Masson-Fontana silver stain provides direct evidence of spirochaetes and hence can be used as a supplemental or confirmatory test for primary syphilis.

C. Machiavello stain - Chlamydia
The Macchiavello technique is very widely used in rickettsia, especially for infected yolk sacs, and chlamydia even though the colour differentiation of the rickettsiae is undependable and usually of low contrast.

D. Acid fast stain - Staphylococci is not correctly matched.
Staphyloccocus aureus is non-acid-fast bacteria, which upon treatment with acid-alcohol solvent, loses the primary red colour, due to the absence of mycolic acid in gf `its cell wall. This step is followed by the addition of a counterstain, methylene blue. This stains Staphyloccocus aureus blue.

Fat in separated milk is not more than 0.1%.
Most skim milk is created by spinning whole milk in a centrifuge so that the fat droplets separate. To make low-fat milk, one can simply mix skim and whole milk in a fixed ratio.
The fat content of skim milk is 0 - 0.1%.

Order of tolerance of aflatoxin is Guinea fowl > Chicken > Duck.
The presence of aflatoxin B₁ (AFB₁) in poultry diets decreases the hatchability, hatchling weight, growth rate, meat, and egg production, meat and egg quality, and vaccination efficiency, as well as impairing the feed conversion ratio and increases the susceptibility of birds to disease and mortality.
It is greatest in Guinea fowl, then in Chicken followed by Duck.

For production of 1 ml of milk 400 - 500 ml of blood passes through udder.
To produce 1 liter of milk 500 liters of blood have to pass through the udder. When a cow produces 60 liters of milk per day, 30,000 liters of blood are circulated through the mammary gland. This represents a blood flow of 1250 liters per hour.

Proventriculus is a spindle-shaped glandular stomach of the bird.
The avian stomach is divided into a proventriculus and ventriculus or gizzard. The proventriculus is a glandular stomach producing digestive enzymes similar to the stomach in dogs and cats.

Gestation period in horses is 336 days.
Gestation is the period of development during the carrying of an embryo, and later fetus, inside viviparous animals (the embryo develops within the parent).
It is measured in weeks, from the first day of the woman's last menstrual cycle to the current date. A normal pregnancy can range from 38 to 42 weeks. Infants born before 37 weeks are considered premature. Infants born after 42 weeks are considered postmature.
