Answer Details
Question 4 Report
Which of the following forage crops best controls soil erosion in a pasture?
Answer Details
Centrosema pubescens is the forage crop that best controls soil erosion in a pasture. Centrosema pubescens is a leguminous forage crop that has a deep-rooted system that helps to stabilize soil and prevent erosion. It also has a spreading growth habit that helps to form a dense ground cover, which reduces runoff and protects the soil from erosion. In addition, Centrosema pubescens is known for its ability to fix nitrogen, which helps to improve soil fertility and reduce the need for chemical fertilizers. Therefore, Centrosema pubescens is an excellent choice for farmers looking to control soil erosion in their pastures.
Question 5 Report
Failure of the testes to descend into the scrotal sac in livestock is referred to as___________
Answer Details
The failure of the testes to descend into the scrotal sac in livestock is referred to as "cryptorchidism". Cryptorchidism is a condition where one or both testes fail to descend from the abdomen into the scrotal sac, where they normally reside. This condition is relatively common in many species of livestock, including bulls, rams, and boars. Cryptorchidism can have negative effects on fertility and is a heritable trait, meaning that it can be passed on to offspring. Therefore, it is important for livestock producers to identify and cull cryptorchid animals from their breeding programs to maintain herd health and productivity.
Question 6 Report
In the marketing of animal products, middlemen create artificial scarcity in order to_______
Answer Details
The correct answer is "make abnormal profit." Middlemen are individuals or companies who act as intermediaries between producers and consumers of goods or services. In the marketing of animal products, middlemen may create artificial scarcity by limiting the supply of animal products available on the market. By doing so, they can create a situation where demand for the products outstrips supply, which in turn allows them to charge higher prices and make abnormal profits. Artificial scarcity can be created in a number of ways, such as by hoarding products, restricting access to markets, or manipulating prices. In some cases, middlemen may even resort to unethical or illegal practices in order to create scarcity and drive up prices. Ultimately, the practice of creating artificial scarcity can be harmful to both producers and consumers of animal products. Producers may be forced to sell their products at lower prices or may be unable to sell them at all, while consumers may be forced to pay higher prices for essential products.
Question 7 Report
The keeping of honey bees is known as_________
Answer Details
The correct answer is "Apiculture." Apiculture is the practice of keeping honey bees in hives for their honey, beeswax, and other products. Honey bees are important pollinators and play a crucial role in agriculture by helping to fertilize crops and ensure their growth and productivity. The practice of apiculture dates back thousands of years, and has been an important part of human history and culture. Today, beekeeping is practiced around the world, and is an important source of income and livelihood for many people. An apiary is a location where beehives are kept and managed for the purpose of apiculture. Aviculture is the practice of keeping and breeding birds, while silviculture is the management of forests and forested lands. These practices are related to agriculture, but are not the same as apiculture.
Question 8 Report
The process of obtaining wool from a live sheep is known as_______
Answer Details
The correct answer is "Shearing." Shearing is the process of removing the wool fleece from a sheep's body. It is typically done once a year, usually in the spring or early summer, when the sheep's wool is at its longest and heaviest. Shearing is an important part of sheep husbandry for several reasons. First, removing the wool helps to keep the sheep clean and healthy by reducing the risk of parasitic infestations and skin infections. Second, the wool is a valuable commodity that can be used to make a variety of products, including clothing, blankets, and carpets. During shearing, the sheep is typically restrained on a special shearing stand or table. The fleece is then removed using electric or manual shears, which cut the wool close to the skin without injuring the sheep. The wool is then sorted by quality and sent to a processing facility, where it is cleaned, carded, and spun into yarn. Overall, shearing is an important part of the wool production process and helps to ensure the health and well-being of sheep while providing a valuable resource for the textile industry.

Trypanosomes can cause diseases such as African trypanosomiasis, also known as sleeping sickness, and Chagas disease in humans, as well as nagana and surra in animals. Therefore, the answer to the question is Trypanosoma sp.
Question 14 Report
Staggered gait and rough coat are signs which indicate that the animal is_________
Answer Details
Staggered gait and rough coat are signs that indicate that the animal is sick. A staggered gait refers to an unsteady or uneven walking pattern, which can be a sign that the animal is in pain or discomfort. A rough coat can indicate that the animal is not feeling well, as a healthy animal will usually have a smooth, shiny coat. These signs can be caused by a variety of illnesses or diseases, and it is important to seek veterinary care if you notice these symptoms in your animal. Early diagnosis and treatment can help to prevent the illness from becoming more severe and improve the chances of a full recovery.

In West Africa, farm animals are mostly kept for___________
Answer Details
In West Africa, farm animals are mostly kept for food and as a source of income. Livestock such as cows, sheep, goats, and chickens are important sources of protein and other nutrients for many people in West Africa. They are also a source of income, as they can be sold for meat or dairy products, or used for plowing fields and transportation. In addition to their practical uses, farm animals also have cultural and social significance in many West African communities, and may be kept for reasons such as prestige or as a symbol of wealth. Overall, farm animals play a vital role in the daily lives and economies of many people in West Africa, and are kept for a combination of practical, cultural, and economic reasons.
Question 18 Report
Which of the following activities are involved in the process of rumination?
I. Re-chewing
II Regurgitation
III, Vomiting
Answer Details
Rumination is a process of digestion that occurs in ruminant animals like cattle, sheep, and goats. During rumination, the animal regurgitates and re-chews partially digested food, which is also called cud. This process helps to break down the plant matter more thoroughly and extract more nutrients. Vomiting is not part of the process of rumination because it involves the expulsion of undigested food from the stomach, rather than the re-chewing of partially digested food. Therefore, the correct answer is (a) I and II only.
Question 19 Report
An area of land on which forage grass and legumes naturally grow is called________
Answer Details
Question 20 Report
In order to prevent overgrazing of pasture, a farmer should adopt___________
Answer Details
To prevent overgrazing of pasture, a farmer should adopt controlled stocking. Controlled stocking is a management strategy where the number of animals grazing on a particular pasture is regulated to prevent excessive grazing that can lead to degradation of the pasture. This is important because overgrazing can result in the loss of plant cover, which can lead to soil erosion and the degradation of soil quality. By limiting the number of animals grazing on a particular pasture, the farmer can allow the vegetation to recover and regrow, ensuring the sustainability of the pasture for future use. Therefore, the answer to the question is controlled stocking.
Question 21 Report
Which of the following animals is kept mainly for animal traction?
Answer Details
The animal that is mainly kept for animal traction is the "bullock". A bullock is a castrated male cow that is trained to pull heavy loads, such as carts or plows, as a form of animal power. Bullocks are preferred for animal traction due to their strength and docile nature, which makes them easier to train than other animals such as horses or donkeys. In many parts of the world, bullocks are still used for agriculture and transportation, especially in rural areas where machinery is not readily available or affordable. Therefore, the correct option is "bullock".
Question 22 Report
A farmer who has a supply order from a pharmaceutical company is keeping farm animals mainly for_________
Answer Details
The correct answer is "raw materials." When a farmer receives a supply order from a pharmaceutical company, it is likely that they are keeping farm animals for the purpose of providing raw materials for the pharmaceutical industry. Many pharmaceuticals are derived from animal products, such as insulin from pigs or cows, and antibodies from rabbits or goats. By keeping farm animals, the farmer is able to provide a reliable and sustainable source of these raw materials. Farm animals can also provide a variety of other raw materials, including meat, milk, eggs, and leather. These materials are used in a wide range of industries, from food production to fashion. While farm animals may provide some degree of security by providing a source of food and income, and may also have social or recreational value for some people, the primary purpose of keeping them in this context is to provide raw materials for the pharmaceutical industry.
Question 23 Report
Mad cow disease can easily spread on a farm through___________
Answer Details
Mad cow disease, also known as bovine spongiform encephalopathy (BSE), can easily spread on a farm through "overcrowding". Overcrowding occurs when too many animals are kept in a confined space, which can lead to increased stress, aggression, and the spread of infectious diseases. In the case of BSE, the disease is caused by an abnormal protein, called a prion, that can be transmitted through the consumption of contaminated feed or contact with infected nervous tissue. Overcrowding can increase the likelihood of contact between animals and the spread of BSE through contaminated feed or by direct contact with infected animals. Therefore, it is important for farmers to maintain appropriate stocking densities and to implement biosecurity measures to prevent the spread of BSE and other infectious diseases.
Question 24 Report
Which of the following organisms is an ectoparasite?
Answer Details
An ectoparasite is a type of parasite that lives on the outside of the host's body, feeding on blood or other bodily fluids. Among the options provided, the flea is the only organism that fits this description and is an ectoparasite. Fleas are tiny insects that live on the skin of animals, such as dogs and cats, and feed on their blood. They can cause itching, irritation, and even transmit diseases to their hosts. In contrast, the liver fluke and roundworm are internal parasites that live inside the body of their host, while the cattle egret is a bird that does not feed on the bodily fluids of other animals and is not a parasite. Therefore, the answer to the question is Flea.
Question 25 Report
One disadvantage of selection is that_________
Answer Details
One disadvantage of selection is that some good traits may be eliminated. Selection is the process of choosing individuals with desirable traits for breeding purposes. While this process can result in improvement of the population over time, it can also have the unintended consequence of eliminating some good traits that were not the focus of the selection process. For example, if a farmer is only selecting for larger size in their livestock, they may unintentionally eliminate traits such as hardiness or disease resistance that are also important for the health and survival of the animals. This is why it is important to consider multiple traits when selecting individuals for breeding, and to be mindful of the potential trade-offs between different traits. By considering a variety of factors, farmers can help to ensure that their populations continue to be healthy and productive over time.
