Why feeding a prestarter during the suckling period??
Confirmed by several independant research
After weaning, the villus length is reduced substantially

What factor is mostly affecting performance during the nursery period?
Birth weight
Weaning weight
Prestarter intake
Is weaning weight really that important?

100 gram more prestarter (pre weaning) intake is resulting in 50 g/d higher gain during the nursery period
44% of difference in gain during the nursery period can beexplained by a difference in prestarter intake during the sucklingperiod

So feeding a prestarter post-weaning preventing the weaning dip however is it also cost effective?

Post Weaning growth
2 times feeding Pre-weaning:
Dry feed: 6,0 kg/piglets
Week 1: 66,6 g/DLWG (6,4 kg)
Week 2: 228 g/DLWG (7,9 kg)
Week 3: 329 g/DLWG (10,2 kg)
Week 4: 385 g/DLWG (12,9 kg)
Week 5: 500 g/DLWG (16,4 kg)
(FIELD TRIAL DATA DK, 2013)
5 times feeding before weaning:
Dry feed: 6,0 kg/piglets
186 g/DLWG(7,3 kg)
257 g/DLWG (9,1 kg)
371 g/DLWG (11,7 kg)

The effect of a good feeding strategy
The proven health effect
High feed intake reduces intestinal leakage
Average daily feed intake day 0-12 , low FI group: 9 g/d; high FI group: 200 g/d.

Feed, Feeding strategies and health!
Prestarter intake during the suckling period is
▪ Compensate for the limitation in milk production▪ 100 gram extra FI untill wenaing = 50 gram extra DLWG in Nursery▪ Higher amylase and protease = better digest starch and vegetable
protein ▪ Less risks for diarrhea and higher feed intake▪ Less risks for diarrhea = less usage of medication
Prestarter intake post-weaning is
▪ Decreasing the weaning dip = Longer villi = Less ri sk for diarrea▪ Less risks for diarrhea = less use of medication▪ Increasing the feed intake and gain post-weaning ���� finally decreasing days to slaughter▪ Higher slaughter weight = more value per pig
Investment in prestarter pre- and post-weaning, prev ents theweaning dip, is cost effective and improve lifetime preformance!
