protein sources for swine
soybean meal dried distillers grains fish meal meat and bone meal sprayed dried plasma blood meal synthetic amino acids
important amino acids include
lysine
threonine
tryptophan
methionine
high protein causes
diarrhea
CP %
lysine %
1%
vitamins and minerals include
calcium/phosphorus (1.2:1 to 1.3:1) selenium/vitamin E vitamin D Na/Cl Zn Oxide
water
feed manufacturing: roller mill
high throughput; higher variability in particle size
high efficiency roller mill
slower; more consistent particle size
feed composed of
may cause gastric ulcers
need to sequence diets
phases of production
species
provided for medications
holding capacity
at mill
at farm
ingredients
you need _____ to determine feed conversion
feed
of a mill does multiple species, you could have an issue with pigs getting
coarse feed
pigs can be fed _____ unlike cattle
meat proteins
what is the holding capacity
the amount of ingredients
stored feed
cooks, adheres to side of bin, molds
feed outage
poor feed conversion; increased culls; scratches (fighting) tail biting
intestinal torsion
feed withdrawal
18 hours pre-harvest
reduces gut fill
less spillage of intestinal contents
what are the stages of production
boar gestation lactation creep feed/early wean pre-starter starter grower finisher gilt developer
gilts
restricted nutrition= restricted development
~4 lbs/day 2-3 post breeding
gestation BCS
3/5
gestation backfat
0.75-0.8
fetal weight will _____ in last month
double
lactation day 1
4 lbs + 1.5 lbs/piglet
lactation: increase feed for _____
3 weeks
piglets
colostrum/milk (antibodies IgA, fat and protein)
creep feed/early wean
prestarter (multiple phases)
starter (multiple phases)
split sex feedings
social dynaamics
different consumption rates
gilts benefit from higher protein longer
grower pigs
135 lbs
muscle building/frame size
finisher pigs
270 lbs
distributing fat
wet feeders beneficial
need 1 gallon water for every

meat quality
hard, white fat desirable
unsaturationlevel (idoine)
measured at harvest
more _____ fats are less desirable
oxidized
DDGS
cooked kitchen waste
intestinal torsion occurs when
change in feed/water availability
change in feed type
change in competition
change in time of feeding
gastric ulcers
finer ground foods
STRESS
treat with omeprazole
downer sow syndrome
osteoporosis
gestation Ca/P
15 g Ca/12 g P
lactation Ca/P
30-35 g Ca/20-25 g P
salt toxicity
lack of water for 24-36 hours
SLOWLY introduce water
may benefit from steroid admin
eosinophilic pervascular cuffing
mulberry heart disease
vitamin E/selenium deficiency
best, fastest growing
pale, acutely dead pigs
