Question 2 Report

Digestion in the rumen is mainly

catalytic

enzymatic

hormonal

microbial

Answer Details

Digestion in the rumen is mainly microbial. The rumen is the first stomach chamber of ruminants, such as cows, sheep, and goats, where food is broken down by microorganisms, such as bacteria, protozoa, and fungi, that live in the rumen. These microorganisms break down complex carbohydrates and fibrous material in the feed into simpler compounds that can be absorbed and utilized by the animal. This process is known as fermentation, and it produces short-chain fatty acids, which are a major source of energy for the animal. The microbial digestion in the rumen is an essential part of the digestive process of ruminants, and it allows them to extract maximum nutrition from their food.

Question 4 Report

The part labeled I and II are

oesophagus and crop

rumen and reticulum

ovary and oviduct

infandibulum and magnum

Answer Details

The part labeled I and II are parts of the female reproductive system of birds. The infundibulum is part I and it is the initial portion of the oviduct where the egg is fertilized. It catches the egg from the ovary and provides the sperm with a place to fertilize the egg. The magnum is part II and it is the region of the oviduct where the egg white or albumen is added around the fertilized yolk. This is where the majority of the egg white is added, providing the egg with protein. So, together, the infundibulum and magnum are responsible for fertilization and the addition of the egg white, respectively, in the production of a bird's egg.

Question 7 Report

Selection of animals based on performance of ancestors is called

mass selection

family selection

progeny selection

pedigree selection

Answer Details

The selection of animals based on the performance of their ancestors is called pedigree selection. Pedigree selection involves examining the ancestry or genealogy of animals to identify those with desirable traits, such as high productivity, disease resistance, or other desired characteristics. In pedigree selection, animals with superior genetic backgrounds or ancestors are chosen for breeding to produce offspring with better genetic potential. This is because desirable traits are often inherited from previous generations, and thus animals with a strong pedigree are more likely to pass on these traits to their offspring. Overall, pedigree selection is an important breeding strategy used to improve the quality of livestock and ensure that desirable traits are passed down to future generations.

Question 13 Report

Oestrus cycle in the ewe occurs every

7 - 11 days

12 - 16 days

17 - 21 days

22 - 26 days

Answer Details

The estrus cycle in the ewe occurs every 17-21 days. The estrus cycle, also known as the reproductive cycle, is the recurring process of sexual readiness and fertility in female animals. In the ewe, the estrus cycle lasts an average of 17-21 days, but can range from 14-19 days in some cases. During this time, the ewe undergoes several hormonal changes that prepare her body for mating and potential pregnancy. The estrus cycle is divided into four stages: proestrus, estrus, metestrus, and diestrus. During estrus, which lasts for approximately 30 hours, the ewe exhibits physical signs of sexual readiness such as restlessness, mounting other animals, and vocalization. This is the optimal time for breeding, as the ewe is most likely to conceive during this stage. In summary, the estrus cycle in the ewe occurs every 17-21 days, and during this time, the ewe undergoes hormonal changes that prepare her for mating and potential pregnancy. Estrus, the optimal time for breeding, lasts for approximately 30 hours.

Which of the following body systems determines the type of feed given to an animal?

Circulatory

Digestive

Excretory

Reproductive

Answer Details

The digestive system determines the type of feed given to an animal. The digestive system is responsible for breaking down food into nutrients that the animal can use for energy, growth, and repair. Different animals have different digestive systems that are adapted to their specific diets. For example, herbivores have longer digestive tracts with specialized organs like the rumen for fermenting plant material, while carnivores have shorter digestive tracts adapted for digesting meat. Therefore, the digestive system is the body system that determines the type of feed given to an animal.

Question 16 Report

The incubation period of chicken egg is

17 days

21 days

28 days

30 days

Answer Details

The incubation period of a chicken egg is 21 days. During this time, the egg is kept warm and humid in an incubator or under a brooding hen. The incubation period is the time it takes for the embryo inside the egg to develop and grow into a chick. During the incubation period, the temperature and humidity levels need to be carefully controlled to ensure proper development of the embryo. If the temperature is too high or too low, or if the humidity levels are not optimal, the embryo may not develop properly or may not hatch at all. On the 21st day of incubation, the chick will begin to "pip," or crack, the shell from the inside using its egg tooth, which is a small protuberance on the beak. After hatching, the chick will continue to rely on a heat source for several weeks until it is able to regulate its body temperature on its own. Overall, the incubation period of a chicken egg is 21 days and is a crucial time for the development of the chick inside.

Question 21 Report

The system in which a lamb is raised by another ewe is known as

feeding

fostering

rearing

weaning

Answer Details

The system in which a lamb is raised by another ewe is known as fostering. Fostering is a management practice commonly used in sheep farming, whereby a lamb is removed from its biological mother and placed with another ewe that is not its biological mother. The ewe that takes on the lamb acts as a foster mother, providing milk and care for the lamb as if it were her own offspring. This can be necessary if the biological mother has died, has too many lambs to care for, or if a lamb is rejected by its mother. In contrast, rearing refers to the general process of raising young animals, which includes feeding, care, and management until the animal reaches maturity. Weaning refers to the process of gradually transitioning a young animal from its mother's milk to solid food, typically by removing it from the mother's care and feeding it alternative sources of nutrition. Therefore, fostering is the correct term to describe the system in which a lamb is raised by another ewe.

Question 27 Report

The number of teats in a cow is

two

four

six

eight

Answer Details

A cow typically has four teats. Teats are the small projections on the udder of female mammals, such as cows, that secrete milk for their young. Cows are known for their large udders, which can contain up to four mammary glands, one for each quarter of the udder. Each mammary gland has its own teat, which is used to extract milk during milking. Having four teats is the most common arrangement in cows, although some may have extra teats, known as supernumerary teats. These extra teats do not produce as much milk as the regular teats and are often removed to prevent infection or injury to the cow. In summary, a cow typically has four teats, one for each quarter of the udder, which are used to extract milk during milking. While some cows may have extra teats, having four is the most common arrangement.

Question 29 Report

Which of the following identification methods could be used in poultry production?

Banding

Branding

Notching

Tattooing

Answer Details

The identification method that could be used in poultry production is banding. Banding involves attaching a small, numbered plastic or metal band to the bird's leg. The band is usually placed on the bird's right leg, although in some countries it is placed on the left leg. The band serves as a unique identifier for each bird, allowing farmers to keep track of individual birds and monitor their health, growth, and production. Branding and notching are also used as identification methods in some types of livestock, but they are not suitable for poultry because they can cause injury or infection. Tattooing, on the other hand, can be used in poultry production, but it is less common than banding because it requires specialized equipment and training. Tattooing involves placing a small, permanent mark on the bird's skin using ink or a needle. Overall, banding is a simple, safe, and effective method of identifying poultry in commercial production.

Question 31 Report

An example of a non ruminant herbivore is

cattle

horse

pig

sheep

Answer Details

An example of a non-ruminant herbivore is a horse. Non-ruminant herbivores are animals that have a simple stomach and cannot efficiently digest tough plant materials. Instead, they rely on microbial fermentation that occurs in their large intestine to break down fibrous plant materials. Horses are an example of non-ruminant herbivores as they have a single-chambered stomach and a relatively small, simple cecum (a pouch that connects the small and large intestine) where microbial fermentation occurs. In contrast, ruminant herbivores, such as cattle, sheep, and goats, have a complex, multi-chambered stomach that allows for more efficient fermentation of plant materials. Therefore, horses, being non-ruminant herbivores, have a different digestive system than cattle, sheep, and goats, making them an example of a non-ruminant herbivore.

The movement of digested feed into the bloodstream is known as

absorption

digestion

egestion

ingestion

Answer Details

The movement of digested feed into the bloodstream is known as absorption. Absorption is the process by which nutrients from digested food are taken up into the bloodstream to be transported to the rest of the body. This occurs in the small intestine, where the digested food is broken down into smaller molecules that can be easily absorbed into the bloodstream. Digestion is the process by which food is broken down into smaller, more easily absorbable molecules. Ingestion is the process of taking food into the body through the mouth. Egestion is the process of removing waste products from the body, typically through defecation. Absorption is an important step in the process of digestion as it allows the body to access the nutrients it needs to function properly. The nutrients are transported through the bloodstream to the cells and tissues where they are used to support growth, repair, and other functions.

Question 35 Report

Lush green forage is wilted before feeding to ruminants to prevent

anaemia

Bloat

Ketosis

tetany

Answer Details

The wilting of lush green forage is done to prevent Bloat in ruminants. Bloat is a condition that occurs when gas accumulates in the rumen (stomach) of ruminants, such as cows or sheep, and cannot be expelled. This can cause discomfort, difficulty breathing, and even death in severe cases. When fresh forage is consumed, it contains a lot of moisture and can produce excessive amounts of gas during fermentation in the rumen. This gas can cause the rumen to distend, making it difficult for the animal to breathe and leading to bloat. Wilted forage, on the other hand, has a lower moisture content and therefore produces less gas during fermentation in the rumen. This reduces the risk of bloat and makes it safer for ruminants to consume. In summary, the wilting of lush green forage is done to prevent bloat in ruminants by reducing the amount of gas produced during fermentation in the rumen.

Question 36 Report

Which of the following excretory organs maintains a healthly balance of body fluids in farm animals?

Kidney

Liver

Lung

Skin

Answer Details

The kidney is the excretory organ that maintains a healthy balance of body fluids in farm animals. The kidney is a vital organ that plays a crucial role in regulating the water balance and removing waste products from the body of farm animals. The kidney filters the blood, removing excess water, salts, and other waste products such as urea and creatinine. These waste products are then excreted in the form of urine. The kidneys also help to regulate the concentration of electrolytes such as sodium, potassium, and chloride in the body fluids of farm animals. They are able to adjust the amount of water and electrolytes that are excreted in the urine to maintain a healthy balance. In addition, the kidney plays an important role in maintaining blood pressure and producing hormones that help to stimulate red blood cell production and regulate calcium metabolism. Overall, the kidney is a vital organ in farm animals, ensuring that the body fluids are balanced and that waste products are removed from the body.

Muscle rigidity and non-responsiveness to stimulus in dead farm animals is known as?

muscle fatigue

tendering

rigor mortis

rough muscles

Answer Details

Muscle rigidity and non-responsiveness to stimulus in dead farm animals is known as rigor mortis. This happens due to the depletion of ATP molecules that cause the inability of muscle fibers to relax. As a result, the muscle fibers remain contracted, causing the body to become stiff and rigid. The onset of rigor mortis usually occurs within a few hours after death and can last for up to 48 hours, after which it gradually disappears due to the breakdown of muscle tissues.

Question 40 Report

Anaemia in farm animals is caused by

sulphur deficiency

magnesium deficiency

iodine deficiency

iron deficiency

Answer Details

Anaemia is a condition characterized by a deficiency of red blood cells or haemoglobin in the blood, which can lead to weakness, fatigue, and other health problems. In farm animals, anaemia is commonly caused by iron deficiency. Iron is an essential mineral that plays a key role in the formation of red blood cells and haemoglobin, which carry oxygen from the lungs to the body tissues. When an animal does not get enough iron in its diet, it cannot produce enough red blood cells, leading to anaemia. This can happen if the animal is not getting enough iron-rich feed or if its body is not absorbing iron properly. In addition to iron deficiency, other factors can contribute to anaemia in farm animals, including parasitic infections, chronic disease, and genetic disorders. However, iron deficiency is one of the most common causes of anaemia in livestock and can be prevented through proper nutrition and management practices. In summary, anaemia in farm animals is caused by a deficiency of red blood cells or haemoglobin in the blood, often due to inadequate iron intake. Iron deficiency can be prevented by providing animals with a balanced diet that includes sufficient iron-rich feed and managing their health and nutrition to prevent parasitic infections and other underlying conditions.
