Topic 7: Nursery Pigs Flashcards
How many days?:
Weaned pigs
Stay in nursery:
18-26 days old 12-20lbs (weaned)
36-46 days in nursery until 40-70 lbs at 6-7 weeks old
How do we fill the nursery?
AIAO
Consider agonistic behaviors
Sort based on weight
then you could sort based on gender
Barrows=higher feed intake than gilts so they grow faster
Temp for weaners in nursery
80F at least
Gradually cool them to 70F dropping .5F a day after 1st week in
Lower temp 10F at night
Where do pigs go to the bathroom?
Definitive areas so there are slotted floors
What could floors be made of?
Coated metal, plastic, woven wires
Large pen = how many pigs?
Small?
100
10
Feed space is how many inches?
What are feeders like?
What do we do about feeding?
12-14 inches
long (less pigs at once) or round (more)
prevent feed buildup
Dont restrict feed intake and keep at floor level
Pig shouldnt be able to climb into feeder
Waterers?
Nipple drinkers (more chance for injury)
Swinging drinkers (less chance of injury)
Bowls
What is the pen design like?
Raised decks with gates and grates
How do we treat nutrition after 21 day milk diet
High level of protein and digestible AA
Low level of feed intake that is high quality in nutrients and no much fat because they have a hard time utilizing it
They need these because a switch from liquid to solid is hard on gut biome
They developing an immune system and their digestive system is changing
What AA is high when on milk?
What does it gradually change to
Lactase is high
Protease and lipase gradually rise as their diet changes (protease breaks down sugar; lipase breaks down protein)
Phase I feeding
weaning to 11 lbs
multi protein sources (plasma, fish meal, whey, SBM)
Methionine is supplemented (essential AA first limiting in pigs)
lactose is added (20-25%)
carbohydrate component like oats or wheat
5-6% fat
Zinc oxide or copper sulfate added to promote growth
Phase II Feeding
11-15 lbs
Continuation of Phase I
decrease complexity of diet
no need to stimulate feed intake
increase SBM Gradually (most economical pig protein source)
Lactose added at 15-20%
3-5% fat
still give growth promotents
Phase III Feeding
15-25 lbs
Corn-SBM with dried whey
AA can be added
Alt. ingredietns ($) Could be included
3-5%fat
growth
Phase IV Feeding
25lbs
Grain-SBM
Lowest cost of phases to make
Most of total cost because consumption is greatest
