Growing-Finishing Pig Management Outline

• 1. Moving pigs into the GF-Barn
• 2. Feeding GF pigs and daily management
• 3. Health considerations
• 4. Performance objectives/benchmarking

3
1.1. Moving pigs into the GF barn

• Sort by size and sex
• Leave one or two pens empty
• Check feeders and water nipples

4
2. Feeding GF Pigs and daily management
5
2.1 Feeding GF Pigs

• Phase Feeding
• 3 to 5 diets during GF period
• Varies in amino acid and phosphorus content
• Feed according to smallest pigs in group
• If pigs lt 25 kg, include animal protein in diet 1
  (i.e. fish meal)
• Feed separate diets to barrows and gilts

6
2.2 Phase Feeding
LYSINE
125 kg
20 kg
7
2.3 Feeding GF Pigs, cont

• Restrict feed intake in late finishing if
  possible
• Feed low energy diet to barrows in late finishing
  if ad libitum feeding system

2.4 Lean Deposition and Feed Intake
Fat
Lean
FI
9
2.5 Dietary Amino Acids conc.

• Calculate amino acids as daily req.
• Diff. Between genotypes
• Use Ideal protein
• Find lysine req.
• If straw bedding, increase AA conc.

10
2.6 General Feeding Management

• Check feeders and water nipples
• Avoid feed wastage
• Check access for pigs

11
2.7 Daily Chores in GF barn

• Check pigs
• Get them up and moving
• Move small pigs and sick pigs if necessary
• Treat sick animals
• Check ventilation, heat, humidity

12
3. Health Consideration
13
3.1 Importance of Health

• 1 reason for poor performance in GF pigs is
  poor health
• Resp. Tract diseases most important
• Mycoplasma, Pneumonia, and PRRS
• GI-tract diseases
• Dysentery, ileitis

14
3.2 High health pigs

• High Health pigs
• SPF pigs
• SEW pigs
• Vaccinated pigs

15
3.3 If diseases in barn

• Bleed pigs
• Determine if vaccination should be initiated
• Determine if medication program will help

16
4. Performance Objectives/Benchmarking
17
4.1 What is important in GF barn

• Feed to gain conversion
• Feed price
• Average daily gain
• Death losses

18
4.2 What is important in GF barn, cont.

• Record keeping is important
• Set production goals
• Evaluate actual performance
• Check new technologies

19
4.3 Realistic objectives for performance

• ADG 900 g (From 20 to 120 kg)
• Gain to feed 0.4 (FCR 2.5)
• Mortality lt 2

20
4.4 How to evaluate performance

• Record all death losses and calculate percent
  mortality
• Record reasons for mortality
• Follow ADG and ADFI in a few average pens
• Weigh pigs every week
• Measure Feed intake
• Calculate ADG, ADFI, and GF

21
4.5 Turn around in barn

• From 20 to 120 Kg 100 kg gain
• 900 g ADG 111 days on average
• 111 days 16 weeks
• Add 2 weeks for tailenders cleaning
• Total turnaround 18 weeks
• Yearly turnaround 2.88

22
4.6 Calculating Capacity

• 1000 head GF barn
• 2.88 turns per year 2880 pigs/year

23
4.7 Importance of ADG
24
4.8 Calculating GF Needs

• 600 sow farrow to finish operation
• Biweekly farrowing schedule
• 600 pigs weaned every other week
• One barn constructed per weaning group

4.9 Number of GF barns needed
