Question 1
4 / -1

The term "breed" refers to

A
a group of animals not related by descent but similar in most characters

B
a group of animals related by descent and similar in most characters

C
a group of animals related by descent but have almost different characteristics

D
a group of animals neither related by descent nor have similar characteristics

Solution

Breed is a group of animals related by descent and similar in most characters like general appearance, features, size, configuration, etc.
Question 2
4 / -1

Which of the following is the "bird flu virus"?

A
H₅N₁

B
Haemophilus influenzae

C
HIV

D
Rhino virus

Solution

Bird flu is a form of influenza occurring in poultry mainly in Japan, China and Southeast Asia. It is caused by a virus, H₅N₁ capable of spreading to humans.
Question 3
4 / -1

Given below are four statements (A - D) each with one or two blanks. Select the option which correctly fills up the blanks in any two statements.
(A) Multiple ovulation (i) transfer technology is for (ii) improvement.
(B) In it a cow is administered (i) to induce follicular maturation and (ii) ovulation.
(C) Instead of one egg per cycle, (i) eggs are produced through it.
(D) The fertilised (i) at (ii) celled stages are recovered non-surgically and transferred to surrogate mothers.

A
(A)-(i) sygote, (ii)pureline; (B)-(i)oestrogen, (ii) poly

B
(A)-(i) embryo, (ii) herd; (D)-(i) zygote, (ii) 4-6

C
(C)-(i) 6-8; (D)-(i) eggs, (ii) 4-8

D
(B)-(i) FSH, (ii) super; (C)-(i) 6-8

Solution

Multiple Ovulation Transfer Technology is a programme for herd improvement. In this, a cow is administered with FSH activity to induce superovulation by follicular maturation due to which it yields 6-8 eggs per cycle instead of one egg. The fertilised eggs at 8-32 celled stages are recovered non-surgically and transferred to surrogate mothers. The genetic mother is available for another round of superovulation. This technology helps to increase herd size in a short time.
Question 4
4 / -1

Study the following statements regarding inbreeding and select the incorrect ones.
(i) The inbreeding strategies allow the desirable ualities of two different breeds to be combined.
(ii) It increases homozygosity.
(iii) It also helps in elimination of less desirable genes.
(iv) Continued inbreeding increases fertility and productivity.

A
(i) and (ii)

B
(ii) and (iii)

C
(iii) and (iv)

D
(i) and (iv)

Solution

Inbreeding strategies allow the desirable qualities of more closely related individuals to be continued within the same breed for 4-6 generations. It increases homozygosity and thus, is necessary for evolving a pure line. Continued inbreeding, especially close inbreeding usually leads to reduces fertility and even productivity. This is called inbreeding depression.
Question 5
4 / -1

Artificial breeding of cattle is brought about by

A
Artificial insemination

B
Superovulation and embryo transplantation

C
MOET

D
All of these

Solution

Artificial breeding method of cattle involves following methods:
(i) In artificial insemination (Al) method, the semen of superior male is collected and injected into the reproductive tract of the selected female by the breeder. The semen can be used immediatel or can be frozen for later use.
(ii) In multiple ovulation embryo transfer technology (MOET) method, hormones (with FSH-like activity) are given to the cow for inducing follicular maturation and super ovulation. Instead of one egg, which they usually giver per cycle, they produce 6-8 eggs. The cow is either mated with a best bull or artifically inseminated. The embros at 8-32 cells stage are recovered and transferred to surrogate mothers. The genetic mother is available for another super ovulation. MOET has been done in cattle sheep, rabbits, buffaloes, mares, etc.
Question 6
4 / -1

Crossing of individuals of two different species to produce a hybrid is called

A
interspecific hybridization

B
intervarietal hybridization

C
intergeneric hybridization

D
intravarietal hybridization

Solution

In interspecific hybridisation, a species is mated with a different related species of the same genus. Interspecific hybrids are generally difficult to produce, but they are important in plant breeding, particularly in breeding for disease resistance. This is also called intrageneric hybridisation.
Question 7
4 / -1

A is an improved breed of cattle and B is an improved breed of chicken, Which of the following options correctly identifies A and B?

A
A-Jersey, B-Leghorn

B
A-Surti, B-Sangamneri

C
A-Marwar, B-Sirohi

D
A-Beetal, B-Jamunapari

Solution

Jersey is an exotic cattle breed from Island of Jersey in English channel. Leghorn is a Mediterranean breed of chicken.
Question 8
4 / -1

Given below are four statements (i)-(iv). Which two of the following statements are correct?
(i) It is estimated that more than 70 percent of the world livestock population is in India and China.
(ii) Stringent cleanliness and hygiene (both of the cattle and the handlers) are paramount importance while milking, storage and transport of the milk and its products.
(iii) Out-breeding is the breeding between animals of the same breed only.
(iv) Crosses between different breeds is called inbreeding.

A
(i) and (ii)

B
(iii) and (iv)

C
(i) and (iv)

D
(ii) and (iii)

Solution

Out-breeding is the breeding of unrelated animals which may be between individuals of the same breed but having no common ancestors for 4−6 generations or different breeds or different species. Inbreeding is breeding between animals of the same breed for 4−6 generations.

Solution

Dairy farming is the management of animals for milk and its products for human consumption. The processes and systems that increase yield and improve the quality of milk are: health care and social well being of the animals; suitable environmental conditions like adequate ventilation, optimum temperature, sufficient light etc; protection against disease; regular inspection by veterinary doctor and proper record keeping.
Question 15

Honey is used as laxative, antiseptic and sedative.

Solution

Products of honeybee are honey, beeswax, bee venom and royal jelly. Medicinal importance includes its uses as laxative, antiseptic, sedative, etc. It is also used against digestive disorders.
