*NUMBER 1 👇🏻👇🏻*
*(1a)*
Fertilization in farm animals is the process by which a sperm cell from the male fuses with an egg cell from the female to form a zygote. This process typically occurs within the female reproductive tract and marks the beginning of the development of a new individual. Fertilization results in the combination of genetic material from both parents, leading to the formation of a genetically unique offspring.
*(1bi) Prolactin :*
*(Pick Any One)*
--- Stimulates milk production in the mammary glands.
--- Influences reproductive behavior and function.
--- Plays a role in regulating the immune system.
--- Affects metabolic processes in various tissues.
--- Influences maternal behavior and bonding.
*(1bii) Oxytocin :*
*(Pick Any One)*
--- Stimulates uterine contractions during labor.
--- Facilitates the milk ejection reflex during breastfeeding.
--- Promotes social bonding and trust between individuals.
--- Influences sexual arousal and behavior.
--- Helps reduce stress and anxiety levels.
*(1biii) Relaxin :*
*(Pick Any One)*
--- Relaxes the pelvic ligaments during pregnancy.
--- Facilitates cervical dilation during labor.
--- Promotes blood vessel growth in the uterus.
--- Aids in the remodeling of collagen in tissues.
--- Exhibits anti-inflammatory properties.
*(1biv) Testosterone :*
*(Pick Any One)*
--- Promotes the development of male secondary sexual characteristics.
--- Stimulates the production of sperm in the testes.
--- Enhances muscle mass and strength.
--- Increases bone density and strength.
--- Influences mood and behavior.
*(1c)*
*(Pick Any Four)*
--- Snails are a good source of protein, iron, and other essential nutrients.
--- Snail farming can be a profitable venture, providing income for farmers.
--- Snail farming requires minimal investment and is easy to manage.
--- Snail farming is environmentally friendly and requires little space.
--- Snail slime has potential medicinal applications, including wound healing.
--- Provides an alternative source of protein, contributing to food security.
--- Snails are a delicacy in many cultures, enhancing culinary diversity.
*NUMBER 3 👇🏻👇🏻*
*(3a)*
In animal nutrition, a diet refers to the combination of feed ingredients provided to an animal over a period, which meets its nutritional requirements for maintenance, growth, reproduction, and lactation. A balanced diet ensures that the animal receives all the necessary nutrients, including proteins, carbohydrates, fats, vitamins, and minerals.
*(3b)*
*(Pick Any Two)*
--- Molasses is rich in sugars, which promote the growth of lactic acid bacteria, improving the fermentation process and the preservation of the silage.
--- The sweet taste of molasses makes the silage more palatable, encouraging animals to consume more.
--- Molasses adds energy to the silage, which is beneficial for the animals' growth and productivity.
--- Molasses helps to bind the silage particles together, reducing dust and making the feed easier to handle and less wasteful.
--- Molasses can help to regulate the moisture content of the silage, preventing spoilage due to excessive dryness or wetness.
*(3c)*
*(Pick Any Three)*
--- High nutritional value
--- Diverse plant species
--- Good ground cover
--- Pest and disease resistance
--- Sustainability
*(3d)*
*(Pick Any Three)*
--- Implementing rotational grazing systems to prevent overgrazing and allow vegetation recovery.
--- Introducing improved forage species and reseeding degraded areas to enhance plant diversity and productivity.
--- Applying appropriate fertilizers and soil amendments to improve soil health and plant growth.
--- Developing water sources and irrigation systems to ensure adequate water supply for plants and animals during dry seasons.
--- Implementing measures such as contour plowing, terracing, and planting cover crops to prevent soil erosion and maintain land productivity.
*NECO ANIMAL HUSBANDRY :*
*NUMBER 5 👇🏻👇🏻*
*(5a)*
*(Pick Any Three)*
--- Regular immunization schedules to protect animals against common infectious diseases.
--- Providing balanced diets to strengthen the immune system and overall health.
--- Maintaining clean living environments, including regular cleaning of barns and equipment.
--- Controlling the movement of people, animals, and equipment to prevent the introduction and spread of pathogens.
--- Routine health inspections to detect and treat diseases early.
*(5b)*
*(Pick Any Two)*
--- Isolating infected or exposed animals to prevent the transmission of contagious diseases.
--- Monitoring animals for signs and symptoms of illness before they join the main herd.
--- Meeting legal requirements for animal movement and disease control.
--- Safeguarding the health of existing livestock by preventing the introduction of new pathogens.
--- Minimizing the financial impact of disease outbreaks through early detection and containment.
*(5c)*
*(Pick Any Five)*
--- Skin Irritation, causing intense itching, redness, and inflammation.
--- Hair Loss, leading to bald patches due to excessive scratching and grooming.
--- Weight Loss, resulting from stress and decreased feed intake.
--- Reduced productivity, leading to lower milk yield, egg production, or growth rates due to discomfort and stress.
--- Secondary Infections, causing increased susceptibility to bacterial or fungal infections due to damaged skin.
--- Blood lood from feeding mites, leading to a reduction in red blood cells.
--- Restlessness, irritability, and decreased social interactions.
--- Severe infestations can lead to death, especially in young or weakened animals.
