Animal Husbandry MCQ Question and Answer | Agriculture MCQ Question

Desi hen is said to be ideal for hatching chicken.
Desi hens proved to be ideal for this purpose. Only 10 to 12 eggs can be put under 1 hen. This method of hatching is highly unsatisfactory for large-scale production of baby chicks. Incubators, which provide similar environment as that of broody hens, but are more efficient, are used at present for hatching of eggs.

Yellow colour of egg is due to Xanthophyll.
The yolk is the nutrient-bearing portion of the egg whose primary function is to supply food for the development of the embryo.
Egg yolk is a source of lecithin, as well as egg oil, for cosmetic and pharmaceutical applications. Based on weight, egg yolk contains about 9% lecithin.
The yellow color is due to lutein and zeaxanthin, which are yellow or orange carotenoids known as xanthophylls.

Silica is most important in inhibiting the digestibility of paddy straw.
The presence of silica in the outer layer of rice straw reduces enzymatic hydrolysis and ethanol production yield.
Silica removal from rice straw was investigated through various alkali treatments. The results showed that sodium carbonate could effectively remove silica from the straw (> 91%).

Maize fodder (green) comes under poor grade in quality.
Maize green forage has a relatively low protein content (3 - 13% of DM) and a high fibre content (crude fibre 19 - 36% of DM).
Depending on the stage of harvesting, it can be rich in starch (up to 30% of DM or more) and, therefore, a source of energy.

The largest nematode of domestic animals is Dioctophyma renale.
The Dioctophyma renale is a worldwide occurring nematode, known as giant kidney worm. It is the largest parasite nematode infecting domestic animals.
Parasitism by this nematode has been described in different animal species, including in humans.

The dose of a drug that kills 50% of the population is known as LD₅₀.
LD stands for "Lethal Dose". LD₅₀ is the amount of a material, given all at once, which causes the death of 50% (one-half) of a group of test animals. The LD₅₀ is one way to measure the short-term poisoning potential (acute toxicity) of a material.
The LD₅₀ can be found for any route of entry or administration but dermal (applied to the skin) and oral (given by mouth) administration methods are the most common.

Seasonal breeders are Sheep.
The animals that undergo mating only during a specific time of the year are called seasonal breeders.
Sheep are seasonal breeders in temperate regions, meaning that they experience distinct periods of sexual activity or inactivity annually. Specifically, sheep are short day breeders, breeding at times of the year when the day length is shorter and night time longer.

The body temperature of pig is 100.9° - 104.9°F.
Pigs can't sweat, they need help staying cool on hot days. During hot weather a pig's temperature may be elevated. If its temperature is raised, allow the pig to cool off and re-take the temperature in 15 minutes.

Ranching is common practice in Australia.
Ranching is the practice of raising herds of animals on large tracts of land. Ranchers commonly raise grazing animals such as cattle and sheep.
Ranching is common in temperate, dry areas, such as the Pampas region of South America, the western United States, the Prairie Provinces of Canada, and the Australian Outback. In these regions, grazing animals can roam over large areas.

Urea treatment of straw increases CP and DCP, TDN and Dry matter digestibility and feed intake.
Urea, when used for the treatment of straw enhances the nutritional quality of straw in terms of increased nitrogen content, improved palatability and digestibility of straw. During the treatment process, ammonia is generated from urea, and in the presence of water it forms the alkali named ammonium hydroxide.
CP is Crude protein, DCP is Digestible crude protein, and TDN is total digestible nutrient.
