Poor lactation
Poor quality/quantity of colostrum
Higher piglet mortality

Anoestrus at weaning
45
What is wallowing?
Wallowing is a behaviour seen in pigs where they will roll around and cover themselves in mud or water to cool off and protect their skin from the sun
46

Increased number of teats
Good mothering
47
What are the three methods of boar contact that can be used to stimulate puberty in gilts?
Full contact
Adjacent pens
Vocal and visual contact
48
At what age should gilts be served?
32 to 34 weeks of age (or after 2 to 3 oestrous cycles)
49
What is the ideal weight for a gilt before being served?
140 - 150kg
50
What are the four factors which could affect oestrus onset in sows?
Lactational anoestrus
Stressors
Nutrition during lactation and post-weaning
Seasonal effects (sows are less fertile in autumn)
51
What are the three signs of oestrus in a sow?
Restlessness
Mounting
Moist, red, swollen vulva
52
What are the three advantages of artificial insemination (AI) in the pig industry?
Introduces new genetics into the herd
Disease control
Supplements natural service so the boar isn't overworked
53
What is the main disadvantage of artificial insemination (AI) in the pig industry?

54
At what temperature should boar semen be stored for artificial insemination?
17.5°C
55
What are the two essential post service management procedures?

Reduce feed level for 72 hours to maximise embryo survival
56
How should you alter the sow diet during gestation?
Four to five days post-serving, increase the feed according to body condition and maintain this increased feed for the first 7 weeks of gestation to assist in placental growth. At day 90 of gestation, drop the feed back to maintenance feed. Reduce feed further two days prior to farrowing to prevent udder congestion
57
What are the six signs of farrowing in sows?
Restlessness
Loosened vulva
Nesting
Colostrum dripping
Tail twitching
Straining
58
What are the three main factors contributing to piglet mortality at birth?
Low birth weight
Below ambient temperature
Poor maternal behaviour
59
Which three management procedures can be done to reduce piglet mortality at birth?
Dry the piglets
Use heat lamps/heat pads
Ensure adequate colostrum intake
60
What should be done to treat splayed legs in piglets?
If only the hindlimbs are splayed, the legs can be tied
61
Which three processing procedures should be carried out in piglets?
Tooth reduction
Tail docking
Iron supplemention
62
What can be done to reduce the risk of Post Weaning Diarrhoea in piglets?
Creep feeding from 4 days old to mature the gut in anticipation of weaning
63
In the UK, what is the minimum age at which piglets can be weaned from the sow?
Piglets can only be weaned from the sow at 28 days of age
64
How should the sow diet be altered post weaning?
When the piglets have been weaned from the sow, reduce the sow feed by half for the first 24 hours. The sow can then be fed ad lib in an attempt to quickly return the sow to a positive energy balance
65
What kind of diet can be used to reduce the weaning to service interval in sows?
A high stach and high sugar diet (known as flushing) can reduce the weaning to service interval in sows
66
What is the most common indoor housing system for weaner pigs?
Flat deck housing
67
What can be done to allow less dominant pigs to access adequate feed?
Leave the lights on during the night to allow less dominant pigs to access food when the more dominant pigs are sleeping
68
How do you calculate the food conversion ratio (FCR)?
FRC = Feed Intake / Weight Gain
69
What is the ideal daily live weight gain for a piglet that has been weaned?
500g/day
70
Which behaviour is indicative of boredom in pigs?
Chewing on the bars or other pigs indicates that pigs are not able to exhibit their natural rooting behaviour
71
What is the ideal live weight for a pig before being slaughtered?
88kg live weight
72
How are pigs below 5kg euthanised?
Blunt trauma
73
How are pigs above 5kg euthanised?
