Animal which chew the cud are
Maelezo ya Majibu
The group of animals that chew the cud are "ruminants." Ruminants are a group of mammals that include animals such as cattle, sheep, goats, buffalo, and deer. These animals have a unique digestive system that allows them to break down tough plant material, such as grasses and leaves, by regurgitating and re-chewing their food (known as cud). This process helps to release more nutrients from the plant material, which can then be absorbed by the animal's digestive system. Amphibians, aves (birds), and reptiles do not chew the cud and have different digestive systems.

Management practices in a piggery include the following except
Maelezo ya Majibu
The management practice in a piggery that is not included is weekly vaccination of pigs. Disinfecting pens helps prevent the spread of disease by killing germs and bacteria. Regular cleaning of feed and water troughs ensures that the pigs have access to clean food and water, promoting their health and well-being. Isolating sick animals helps prevent the spread of disease to healthy pigs, and is an important part of disease control in a piggery. However, weekly vaccination of pigs is not a standard practice in a piggery. Pig vaccination schedules vary depending on the specific disease being targeted, the age and health of the pigs, and other factors. Typically, pig vaccination is done on a regular basis, but not necessarily every week. It is important to consult with a veterinarian to develop an appropriate vaccination schedule for your pigs.

Which of the following may cause disease in a fish pond?
Maelezo ya Majibu
All of the options listed can contribute to disease in a fish pond, but poor management practices are particularly significant. Poor management practices can include things like overstocking the pond, failing to maintain proper water quality, not properly cleaning and disinfecting equipment, and not providing adequate nutrition to the fish. These practices can create an environment that is favorable for the growth and spread of disease-causing pathogens, leading to outbreaks of disease in the pond. Mixed stocking refers to the practice of stocking a pond with different species of fish. This can increase the risk of disease by introducing new pathogens or by creating stress in the fish that weakens their immune systems. Liming is the practice of adding lime to a fish pond to adjust the pH of the water. While liming is important for maintaining the health of the fish, it can also increase the risk of disease if not done properly. Harvesting refers to the removal of fish from a pond. While harvesting itself is not a direct cause of disease, it can disrupt the balance of the pond and increase the risk of disease if not done properly. For example, if fish are harvested too frequently or if diseased fish are not properly disposed of, it can create an environment that is favorable for the growth and spread of disease-causing pathogens.

Capital in agriculture includes the following item except
Maelezo ya Majibu
Capital in agriculture refers to the resources and assets used to produce crops and livestock. It includes items such as machinery, buildings, and land. The option that does not belong in this list is "labour". While labour is an important input in agriculture, it is not considered a capital asset. Capital assets are long-term investments that are used to produce goods over time, while labour is a more immediate input that is used to carry out specific tasks. So, labour is considered an operational cost or an expense, rather than a capital asset, in agriculture. To produce crops and livestock, farmers need both capital assets and labour inputs, but labour is not considered a part of the farmer's capital.

The best control ensure for rinderpest disease in cattle is
Maelezo ya Majibu
The best control measure for rinderpest disease in cattle is vaccination. Rinderpest is a highly contagious viral disease that affects cattle and other species of cloven-hoofed animals. It is spread through direct contact between animals or through contaminated feed, water, or equipment. Vaccination is the most effective way to prevent the spread of the disease and protect cattle from getting sick. By vaccinating cattle, they will develop immunity to the virus and will not get sick if they are exposed to it. This helps to break the chain of transmission and reduce the spread of the disease to other animals. Sanitation, such as cleaning and disinfecting pens and equipment, can help to reduce the risk of spreading the virus, but it does not provide immunity to the cattle. The use of antibiotics may help to treat secondary infections, but they do not cure rinderpest itself, which is a viral disease. The eradication of infected stock may help to control the spread of the disease in the short term, but it is not a sustainable solution on its own, as new cases of infection can occur. In conclusion, the best control measure for rinderpest in cattle is vaccination, which provides immunity to the cattle and helps to prevent the spread of the disease.

Maelezo ya Majibu
Birds temporarily store their food in the crop. The crop is a small pouch-like organ located near the bird's throat. It can stretch and expand to store food before it moves down to the rest of the digestive system. The food is softened and moistened in the crop, and then gradually passed on to the gizzard, which is a muscular part of the stomach where food is ground and broken down further. The gizzard is followed by the proventriculus and duodenum, where the food is further processed and digested.

Maelezo ya Majibu
Leguminous cover crops do not reduce the soil microbial population. In fact, they do the opposite - they aid in increasing the soil microbial population. This is because leguminous cover crops have the ability to fix nitrogen from the air and add it to the soil, providing a source of nutrition for soil microorganisms. Additionally, their roots and leaves also add organic matter to the soil as they decompose, which further supports the growth of soil microorganisms. So, leguminous cover crops are beneficial for soil health and fertility, not detrimental.

Maelezo ya Majibu
Cassava is mainly propagated by cuttings. Cassava is a tropical root crop that is widely grown for its edible starchy roots. To grow cassava, farmers usually take cuttings from mature plants and plant them directly into the ground. These cuttings will then sprout roots and grow into new plants. This method of propagation is relatively simple and efficient, and it ensures that the new plants will have the same characteristics as the parent plant. Other methods of plant propagation, such as layering, budding, and growing from seedlings, can also be used, but cuttings are the most commonly used method for propagating cassava.

Maelezo ya Majibu
The recommended agricultural practice in farm settlement schemes is mixed farming. Mixed farming involves the integration of both crop and livestock production on the same farm. This approach provides farmers with a more diverse and stable source of income, as they can earn money from both crops and animals. Additionally, mixed farming can help to improve soil fertility and reduce the risk of crop failure, as the manure produced by livestock can be used as a natural fertilizer for crops. This type of agricultural practice is considered to be more sustainable and resilient than relying solely on one type of production, such as cash crop production or poultry farming.

Under normal circumstances, the concept of consumer sovereignty in agriculture implies that
Maelezo ya Majibu
Consumer sovereignty in agriculture refers to the idea that the consumer, not the farmer, determines what should be produced in the agricultural sector. This means that farmers produce what consumers want to buy, rather than what they think is best to grow. Essentially, the demand of the consumers drives the supply of agricultural products. For example, if consumers demand organic produce, farmers will shift their production towards organic crops to meet that demand. In this way, consumer sovereignty ensures that the needs and preferences of the consumers are being met. However, it's important to note that the concept of consumer sovereignty can sometimes be limited by various factors such as government policies, production costs, and environmental constraints.

Maelezo ya Majibu
The national tree-planting campaign is aimed at stimulating afforestation. Afforestation refers to the process of establishing a forest, or stand of trees, in an area where there was no forest. The goal of the national tree-planting campaign is to increase the number of trees in a specific area, either for conservation purposes, to provide timber, or for other benefits such as improving air quality and reducing soil erosion. Taungya farming involves the planting of trees in fields, where crops are also grown. This type of farming provides benefits to both the trees and the crops, as the trees provide shade and improve soil fertility, while the crops provide food and income. Forest reservation involves setting aside forests for conservation purposes, usually to protect wildlife and their habitats. While all of these practices can contribute to improving the health and sustainability of forests, the primary focus of a national tree-planting campaign is likely to be on afforestation.
