(6ai)
physiological status: Physiological status of farm animals, such as whether they are pregnant, lactating, growing, or in maintenance, significantly influences their nutrient requirements.

(6aii)
Age: Age directly impacts the nutrient requirements and digestive capacity of farm animals. Young animals have higher nutrient needs for growth and development compared to mature animals

(6aiii)
Nutrient composition of feedstuff: Formulating feeds based on the nutrient composition of feedstuff ensures that animals receive balanced diets that meet their specific nutrient requirements.

(6b)
(PICK ANY FIVE)

(i)process of slaughtering
(ii) undergoes dressing
(iii)Cutting and Boning
(iv)transforming raw meat into value-added products
(v)Packaging using appropriate materials
(vi)Storage and Distribution

(6c)
(i)selection: selection refers to the process of choosing animals with desirable traits for breeding purposes, with the goal of improving the overall genetic quality of the herd or flock.

(ii)Pasture: Pasture is an area of land covered with grasses, legumes, or other forage crops that is utilized for grazing by livestock.

(iii)Artificial Insemination: Artificial insemination (AI) is a reproductive technology used in animal production to breed livestock without natural mating

(6d)
(PICK ANY THREE)

(i)meat
(ii)Pelts
(iii)Manure
(iv)Pets
======================

(1a)
(PICK ANY FOUR)
(i) Cattle are ruminants with a complex four-chambered stomach (rumen, reticulum, omasum, abomasum), while poultry have a single-chambered stomach.
(ii) Cattle chew their cud and have the ability to ferment fibrous plant materials in the rumen, while poultry lack this capability.
(iii) Cattle have a longer digestive tract compared to poultry, allowing for more efficient digestion of roughage and cellulose.
(iv) Poultry have a crop and a gizzard, which help grind and store food, while cattle do not have these structures.
(v) Cattle rely more on microbial fermentation in the rumen for nutrient absorption, while poultry have a shorter and more simple digestive system.
(vi) The digestive enzymes and pH levels differ between the two species, with cattle being better adapted to digest fibrous plant materials.

(1b)
(PICK ANY FOUR)
(i) Regularly administering effective anthelmintic (dewormers) to eliminate worms.
(ii) Rotating grazing areas, avoiding overstocking, and properly managing manure to break the worm lifecycle.
(iii) Maintaining clean housing, feeders, and waterers to reduce worm transmission.
(iv) Providing a balanced diet and appropriate nutritional supplements to support the animal’s immune response.
(v) Introducing natural predators of worms, such as certain nematophagous fungi, to reduce worm populations.
(vi) Selecting animals with genetic resistance or tolerance to worm infections to gradually improve the herd’s or flock’s resilience.

(1c)
(PICK ANY THREE)
(i) Crossbreeding: Introducing genetic material from high-performing exotic breeds to improve the productivity and adaptability of local breeds.
(ii) Selective breeding: Identifying and selectively breeding the most desirable traits within the local breed population to enhance desirable characteristics.
(iii) Genomic selection: Utilizing genetic markers and genomic information to guide selective breeding programs and accelerate genetic progress.
(iv)Improving management practices: Optimizing feeding, housing, healthcare, and other management factors to support the expression of the local breed’s genetic potential.

(1d)
(i) CREEP FEEDING
(PICK ANY THREE)
(i) Increased growth rate and weight gain in young animals
(ii) Improved feed conversion efficiency
(iii) Enhanced immune function and disease resistance
(iv) Earlier weaning and transition to solid feed

(ii) DEHORNING
(PICK ANY THREE)
(i) Reduces the risk of injuries to animals and handlers
(ii) Prevents damage to housing, equipment, and other animals
(iii) Facilitates easier handling and management of the animals
(iv) Helps maintain a more uniform herd or flock appearance

=============================
(2a)
(i) Improved animal health and welfare.
(ii) Better control of environmental factors like temperature and humidity.
(iii) Reduced risk of disease transmission.
(iv) Increased productivity and growth rates.
(v) Enhanced reproductive performance.
(vi) Minimized stress levels leading to higher quality products.

(2b)
(i) Preventing aggression and injury among different age groups.
(ii) Avoiding competition for resources such as food and water.
(iii) Minimizing the spread of diseases between age groups.
(iv) Tailoring feeding and management practices to specific age-related needs.

(2c)
(i) Cleaning and disinfecting the entire facility.
(ii) Checking and calibrating heating equipment to maintain appropriate temperature levels.
(iii) Providing clean bedding material.
(iv) Ensuring adequate ventilation.
