This set of Agricultural Biotechnology Multiple Choice Questions & Answers (MCQs) focuses on “Agriculture – New Approaches to Animal Culture”.
1. What is the minimum number of days required to detect pregnancy after breeding using a monoclonal antibody test?
a) 12
b) 24
c) 36
d) 48
View Answer
Explanation: Scientists have developed and patented a monoclonal antibody test to diagnose pregnancy in cows, which could be an important advancement for dairy farmers and cattle breeders.
2. What is the percentage of increase in milk production by genetically engineered bacteria to produce the hormone?
a) 10%
b) 20%
c) 30%
d) 40%
View Answer
Explanation: Bovine growth hormone (BGH) is a naturally occurring hormone that increases milk production in cows. The animal’s milk composition does not change, although it requires greater amounts of and more nutritious feed.
3. Daily injections of BGH to cows is regarded as impractical.
a) True
b) False
View Answer
Explanation: Researches are developing injectable slow release formulations, as well as ways to transfer the BGH gene into the animals. The latter process is complicated by the fact that farmers would not want unregulated release of the hormone.
4. Which is the animal to which PGH is injected and administered?
a) Dogs
b) Pigs
c) Cows
d) Rats
View Answer
Explanation: PGH stands for porcine growth hormone. PGH greatly stimulates the pig growth performance. It elevates their growth rate, feed efficiency and ratio of muscle to fat.
5. PGH depresses the growth of fatty tissue.
a) True
b) False
View Answer
Explanation: As PGH depresses the growth of fatty tissue, the nutrients are redirected to the muscle growth. As PGH is a naturally occurring protein hormone, it is metabolized by the animal.
6. __________ gene boosts the incidence of twinning and triplets in sheep.
a) Huntingtin
b) ABO
c) Booroola
d) BRCA2
View Answer
Explanation: This gene gives an overall 20-40 percent increase in the number of lambs weaned. Introducing the Booroola gene into other sheep and cattle could offer a fast and reliable way to increase the productivity of ewe and cow herds.
