Quiz: Assistant Agriculture Officer: Animal Husbandry: 01

Correct Answer: 3-5
Colostrum is significantly richer in proteins, especially antibodies, compared to normal milk, typically containing 3-5 times more protein.

Correct Answer: Chokla
The Chokla breed of sheep, found in Rajasthan, is known for producing high-quality carpet-grade wool.

Correct Answer: Changthangi
Pashmina wool, known for its fineness, is obtained from the Changthangi breed of goat found in the high-altitude regions of Ladakh.

Correct Answer: 280-285 days
The average gestation period for cows is approximately 9 months, falling within the range of 280-285 days.

Correct Answer: 20-25 sq. ft.
For adult cows, a covered floor space of 20-25 square feet within the shed is generally considered adequate for basic comfort and movement.

Correct Answer: 15-20%
Hay is forage dried to a low moisture content to preserve it for animal feed. Ideal moisture content is typically between 15-20% to prevent mold and spoilage.

Correct Answer: Virus
Foot and Mouth Disease (FMD) is a highly contagious and economically important disease of cattle, pigs, and other cloven-hoofed animals caused by a virus.

Correct Answer: 2-2.5 kg/100kg body weight
For calculating balanced rations for indigenous cattle, dry matter intake is commonly estimated at a rate of 2 to 2.5 kg per 100 kg of the animal's body weight.

Correct Answer: 10%
Young calves require adequate milk for growth. A common guideline for the first few weeks is to feed milk at a rate of 10% of the calf's body weight daily.

Correct Answer: River buffalo
The vast majority of buffaloes found in India belong to the River buffalo category, which are primarily raised for milk production.

Correct Answer: Chokla
The Chokla sheep breed is native to the arid and semi-arid regions of North West India, particularly Rajasthan, and is well-adapted to these conditions.

Correct Answer: Tympanitis
Feeding excessive amounts of lush, rapidly fermentable green fodder can lead to a build-up of gas in the rumen, causing bloat, also known as Tympanitis.

Correct Answer: HF × Sahiwal
Frieswal is a crossbred cattle strain developed in India by crossing Holstein-Friesian (HF) bulls with Sahiwal cows. The aim was to combine the high milk yield of HF with the heat tolerance and disease resistance of Sahiwal.

Correct Answer: All of the above
Marwari is recognized as a breed name for Camel, Goat, and Horse, all originating from the Marwar region of Rajasthan. Therefore, 'All of the above' is the correct collective answer in this context.

Correct Answer: 3
Avishaan is a composite sheep breed developed by crossing three breeds: Rambouillet, Chokla, and Malpura. It was developed for improved carpet wool production.

Correct Answer: Within 4 to 8 hrs of parturition
Normally, the placenta (afterbirth) in cows is expelled within 4 to 8 hours after calving (parturition). Retention beyond 12 hours is considered abnormal (Retained Foetal Membranes).

Correct Answer: Age
As a cow ages, particularly over successive lactations, there tends to be a gradual decline in milk components like protein, fat, and Solids-Not-Fat (SNF) percentage. Milk yield might increase initially but component percentages often decrease in later life.

Correct Answer: 16-19 days
The normal length of the estrous cycle (the recurring reproductive cycle) in ewes (female sheep) is typically 16 to 19 days, with an average of about 17 days. The period of estrus (heat) itself lasts about 24-36 hours.

Correct Answer: 3-10 days after birth
Disbudding, the removal of horn buds before they attach to the skull, is best performed on calves at a young age, typically between 3 to 10 days after birth. This minimizes stress and risk compared to dehorning older animals.

Correct Answer: Making hay
Making hay, which involves drying forage crops like grasses or legumes to a low moisture content, is a widely practiced, economic, and satisfactory method for preserving forage quality for later use. Straw is primarily bedding, while bundles and heaps are less standardized preservation methods.
