Where is the semen deposited in laparoscopic AI?
-
Cervix
-
Vagina
-
Ovary
-
Uterine horns
Correct Answer
A. Uterine hornsExplanation
In laparoscopic AI, the semen is deposited in the uterine horns. The uterine horns are part of the uterus and they are the site where fertilization occurs in many mammals, including humans. During laparoscopic AI, a small incision is made in the abdomen to access the reproductive organs, and the semen is directly deposited into the uterine horns using a specialized instrument. This allows for a more precise and targeted delivery of the semen, increasing the chances of successful fertilization.Rate this question:
-
- 26.
The sex of the offspring is determined by the male.
-
True
-
False
Correct Answer
A. TrueExplanation
The statement is true because the sex of the offspring is determined by the male. In most species, including humans, males have two different sex chromosomes, known as X and Y. Females have two X chromosomes. During reproduction, the male contributes either an X or a Y chromosome to the offspring, while the female always contributes an X chromosome. If the male contributes an X chromosome, the offspring will be female, and if the male contributes a Y chromosome, the offspring will be male. Therefore, the sex of the offspring is determined by the male.Rate this question:

The number of offspring born to a female is determined by the male.
-
True
-
False
Correct Answer
A. FalseExplanation
This statement is false because the number of offspring born to a female is not determined by the male alone. The number of offspring is typically influenced by both the male and female reproductive systems. The female's reproductive system plays a crucial role in determining the number of offspring through processes such as fertilization, implantation, and gestation. The male's contribution is limited to providing sperm for fertilization. Therefore, it is incorrect to say that the male solely determines the number of offspring born to a female.Rate this question:

Which diet helps to develop a young ruminant's rumen quicker?
-
Milk
-
Grass
-
Hay
-
Grain
Correct Answer
A. GrainExplanation
Grain helps to develop a young ruminant's rumen quicker because it is rich in carbohydrates. The high carbohydrate content in grain stimulates the growth of bacteria in the rumen, which helps in the breakdown of complex compounds and the production of volatile fatty acids. This process helps in the development and maturation of the rumen, allowing the young ruminant to efficiently digest and utilize forage and other feeds. Milk, grass, and hay do not provide the same level of carbohydrates as grain, making grain a more effective diet for rumen development.Rate this question:

Which volatile fatty acid (VFA) is the end product of fiber digestion?
-
Acetate
-
Proprionate
-
Butyrate
-
Caltrate
Correct Answer
A. AcetateExplanation
Acetate is the correct answer because it is the main end product of fiber digestion. When dietary fiber is broken down by bacteria in the colon, one of the byproducts is acetate. Acetate is then absorbed into the bloodstream and can be used as an energy source by various tissues in the body. Proprionate and butyrate are also VFAs produced during fiber digestion, but they are not the primary end products. Caltrate is not a VFA and is not produced during fiber digestion.Rate this question:

Consumption of which feedstuff is most likely to lower rumen pH and make it more acidic?
-
Hay
-
Grain
-
Silage
-
Grass
Correct Answer
A. GrainExplanation
Grain is most likely to lower rumen pH and make it more acidic compared to the other feedstuffs listed. This is because grains are high in starch content, which can be rapidly fermented by rumen microbes, producing volatile fatty acids (VFAs) such as propionic acid. The increased production of VFAs leads to a decrease in rumen pH, making it more acidic. Hay, silage, and grass have lower starch content and are typically fermented more slowly, resulting in a less acidic rumen environment.Rate this question:
