Answer Details

(a) Three factors that could affect the hatchability of specimen J (Egg) are:

1. Temperature: The incubation temperature must be maintained within the optimal range to ensure proper development of the embryo inside the egg.
2. Humidity: The correct level of humidity must be maintained throughout the incubation period to prevent the egg from drying out and to facilitate proper gas exchange.
3. Egg Quality: The quality of the egg itself, such as the age of the egg and the health of the parent bird, can affect hatchability.

(b)(i) Four operations that should be carried out on the first day of production of specimen K (Chick) are:

1. Cleaning and disinfecting the brooding area: The brooding area should be thoroughly cleaned and disinfected before the arrival of the chicks to prevent the spread of diseases.
2. Checking the temperature: The temperature of the brooding area should be checked and adjusted to the appropriate level for the age of the chicks.
3. Providing clean water: Fresh, clean water should be provided to the chicks immediately upon arrival.
4. Providing feed: A starter feed should be provided to the chicks as soon as they arrive.

(ii) Three diseases for which specimen K requires vaccination before it is six weeks old are:

1. Marek's disease: A viral disease that can cause tumors, nerve damage, and other symptoms.
2. Newcastle disease: A viral disease that can cause respiratory problems, nervous system damage, and other symptoms.
3. Infectious bronchitis: A viral disease that can cause respiratory problems, decreased egg production, and other symptoms.

(c)(i) The type of housing unit used for rearing specimen K on arrival at the farm is called a brooder.

(ii) Four equipment which are required in the brooder are:

1. Brooder heater: A heating device is required to maintain the temperature inside the brooder at the appropriate level for the age of the chicks.
2. Waterers: Clean water should be provided to the chicks at all times, so a waterer is necessary.
3. Feeders: A feeder should be provided to the chicks to allow them to access feed easily.
4. Bedding material: The floor of the brooder should be covered with a suitable bedding material, such as wood shavings or straw, to provide a comfortable and clean environment for the chicks.
