Animal Husbandry

The width of a single row animal shed is typically standardized as 20 feet to provide adequate space and comfort for the animals, ensuring proper ventilation and movement.

The gestation period of sheep is approximately 150 days, which is the typical length of pregnancy before lambing.

Mahshana is recognized as a hybrid breed of buffalo. It is developed by crossbreeding Murrah and Surti breeds of buffalo to combine desirable traits like higher milk production and adaptability. The hybridization aims to improve overall productivity and resistance to local environmental conditions.
- Soorti is a distinct breed native to Gujarat, known for moderate milk production.
- Murra is a well-known high milk-yielding breed from Punjab.
- Bhadawari is another Indian breed, known for its fat-rich milk.
Therefore, Mahshana, resulting from crossing Murrah and Surti, is categorized as the hybrid breed.

The hair type known as 'bagh ka hair' or tiger's hair refers to offset hair. Offset hair is characterized by a unique pattern where the scales on the hair shaft are offset or staggered, resembling the texture and appearance of tiger hair. This type of hair has distinctive properties used to describe such patterned hair types.
The other types of hair:
- Woolly hair refers to tightly coiled or curly hair.
- Tandem hair refers to hair arranged in pairs or groups, different from offset.
Hence, the correct answer is Offset hair.

In spraying machines used for pest control, the thick cone type nozzle is preferred. This nozzle produces larger droplets that penetrate dense foliage effectively and reduce drift, ensuring better coverage and pest control efficiency.
- Hollow cone nozzles produce finer droplets which are more prone to drift.
- Flat fan nozzles provide a uniform spray but are generally used for herbicides, not insecticides.
Hence, the thick cone nozzle is the most suitable for spraying insecticides.

Castration in goats is ideally performed at the age of 4 to 6 weeks. Performing castration at this age helps in better healing, reduced stress, and fewer complications. Early castration also influences the growth and development of the goat in a controlled manner.

The average lactation period of a buffalo is approximately 332 days. This period represents the duration during which the buffalo produces milk after giving birth, and it is generally longer than in many other dairy animals. Proper management during this period is crucial for optimal milk production.

The typical volume of semen used for artificial insemination in cows is between 1 to 2 cubic centimeters. This quantity is sufficient to fertilize the cow while ensuring maximum efficiency and minimizing wastage of semen.
