Fertilisation of the ovum in the hen takes place in the:
C. Infundibulum
The ovum is fertilised in the infundibulum within the short time (about a quarter of an hour) before albumen is added. Once the magnum lays down albumen, sperm cannot reach the germinal disc. Sperm are stored near the vagina but fertilisation does not occur there.
In which part of the oviduct does the forming egg spend about 20 hours?
B. Shell gland (uterus)
The shell gland holds the egg for about 20 hours, adding water and salts to the albumen and then the calcium carbonate shell, pigment and cuticle. The magnum takes about 3 hours and the isthmus a little over an hour.
In the domestic hen, the functional reproductive organs are:
A. The left ovary and left oviduct
Only the left ovary and oviduct develop in the hen; the right regress during embryonic life. This is why a hen has a single oviduct opening into the cloaca.
In birds, light stimulates reproduction largely through photoreceptors located in the:
C. Hypothalamus (deep brain photoreceptors)
Birds have photoreceptors deep in the brain, in the hypothalamus, which respond to light passing through the skull and drive GnRH release. Blind birds still respond to photoperiod, so the retina is not the only route.
A broiler flock was placed as 10,000 chicks; 9,550 birds were sold at an average live weight of 2.3 kg. Total feed used was 36,000 kg. What is the feed conversion ratio?
D. 1.64
Live weight produced = 9,550 × 2.3 = 21,965 kg. FCR = 36,000 ÷ 21,965 = 1.639. Using chicks placed (1.57) ignores mortality; 0.61 is the inverse (feed efficiency); 3.77 is kg feed per bird, not per kg.
20,000 broiler chicks were placed and 900 died or were culled before sale. What is the liveability?
B. 95.5%
Liveability = (placed − dead) ÷ placed × 100 = 19,100 ÷ 20,000 × 100 = 95.5%. 4.5% is the mortality; dividing by survivors gives 4.7%; inverting (placed ÷ survivors) gives 104.7%.
The incubation period of the Muscovy duck egg is about:
D. 35 days
Muscovy (Cairina moschata) eggs take about 35 days, clearly longer than common duck eggs (about 28 days). 17–18 days is the Japanese quail.
A fumigation protocol uses formalin and potassium permanganate in the usual ratio of 2 mL formalin to 1 g permanganate. If 60 g of permanganate is used, how much formalin is needed?
C. 120 mL
Formalin = 60 g × 2 mL/g = 120 mL. Halving (30 mL) reverses the ratio; 180 mL multiplies by the whole ratio (2 + 1) instead of the formalin part. Always add formalin to permanganate in a deep container and leave the room at once; formaldehyde is irritant and carcinogenic and restricted in some countries.
In the US grading standard, an egg with a Haugh unit value of 65 would be graded:
B. A
US standard: 72 and above = AA, 60 to 72 = A, below 60 = B. 65 falls in grade A.
The period for which a cleaned and disinfected poultry house is left empty before restocking is called:
D. Downtime
Downtime is the empty period between flocks after cleaning and disinfection. A withdrawal period applies to medicines before slaughter or egg sale; quarantine isolates new or sick animals.
