1

Selected from productive mothers weaned at least 10

2

Excellent conformation especially legs

3

Excellent growth rate up to 60 kg

4

A gilt rearing diet high Ca and PO4

5

Gilts which cycle within 10 days post-arrival/first contact with boar at 90 kg

6

A healthy gilt no mycoplasma, ileitis, erysipelas, PRRSv or SIV post-arrival. Note vaccine programme in place.

7

Good cycling and boar exposure protocols

8

Group houses from introduction to mating

9

Ad lib feeding 2nd cycle until mating - flushing

10

Good light in mating area 500 lux 16 hours on 8 off

11

Breed on the 3-5th cycle post-boar exposure

12

130 kg live weight

13

220 290 days of age

14

18+ mm back fat

 

these last three can only be achieved if gilt selected at 60kg

15

Semen from a boar older than 9 months of age including by AI

Pooled semen

17

Semen from a boar with 3 teats in front of the prepuce

18

Good housing, feeding and management first gestation

19

No mycotoxins in gestation diet

20

No Parvovirus infection post-mating

21

Careful and considerate farrowing area

22

Cool farrowing area post-one week

23

Minimum of 9 piglets to suckle to weaning

24

Extended lactation length to maximize 2nd litter

25

Aid to maximize feed intake 9+ kg by day 18 of lactation
