DanBred breeding animals have an ordinary genetic doable for reproductive efficiency. When a piglet is produced inside the sow all the way through gestation, we additionally need that piglet to live on. And your feeding technique for gestating sows might if truth be told be extremely correlated in your luck within the farrowing unit.
Underneath, our well known pig professional, Thomas Sønderby Bruun, Senior specialist in SEGES Innovation, supplies his key issues at the optimum feeding technique for gestating sows to verify necessary piglets.
1. The significance of optimum feeding all the way through gestation
A not unusual function for pig manufacturers around the globe is that we wish the sow to offer delivery to necessary piglets. We additionally need fast farrowings with a top survival price and a low want of delivery help. The optimum feed technique for gestating sows performs crucial section in achieving that function.
Feeding all the way through gestation serves 3 functions:
- A hit conception and embryo implantation
- Ultimate frame situation for the lactation length
- Optimal uterine and maternal expansion
By way of that specialize in having uniform sows on the finish of gestation, you’ll build up the clutter weight achieve right through lactation.
2. Center of attention on frame situation
You’ll be able to optimise the lactation efficiency of your hyper-prolific sows by means of that specialize in sow frame situation, i.e., backfat.
Backfat size is straightforward to accomplish after a bit follow, and it may be the important thing to extra uniform sows and to succeed in the optimum backfat stage at farrowing. In accordance with a Danish find out about with greater than 3,900 lactation sessions, it is strongly recommended to try for at backfat thickness of 14-17 mm at farrowing to maximize the nursing capability of the sow, and therefore, moderate day by day clutter weight achieve.
The backfat will have to be evaluated at:
- Weaning
- Round 28 days of gestation (or after being pregnant detection)
- 70-80 days of gestation (non-compulsory)
- Farrowing
It is very important put in force a balanced feeding curve right through gestation. You will have to staff the sows in keeping with frame situation: thin, skinny, moderate, and fats sows – and feed them in keeping with that.
3. Feed components for gestating sows
Opting for sure nutritional feed components right through gestation does no longer turn out to be a very simple technique to enhance moderate piglet delivery weight. Extra lysine does no longer build up piglet delivery weight. Whilst different feed components, akin to L-cartinine or arginine, have the possible to impact delivery weight, the consequences aren’t constant.
However, top lysine and protein ranges right through gestation will leads to an excessive amount of muscles, which isn’t excellent. We wish to regulate frame weight achieve of the sows and favour restorage of backfat right through gestation. We wish the sows to have the very best backfat thickness at farrowing.
4. Early to mid-gestation feeding
The touch between the oocyte and the uterus occurs in very early gestation and that’s when the placenta is shaped. You will have to feed the sows to verify optimum placental building to protected robust, necessary piglets.
A new trial at SEGES Innovation will center of attention on carried out feeding of sows in mid-gestation to discover imaginable certain results on piglet delivery weight. The effects are anticipated to be launched round October 2024.
5. Optimum feed stage in overdue gestation
A feed stage of three.4 kg is perfect for sows in overdue gestation, i.e., 3-4 weeks prior to farrowing and till farrowing. This is given to the sow each for upkeep, but in addition to protected the foetal expansion and expansion of the udder.
SEGES Innovation has studied the results of giving further feed in overdue gestation:
- Including 1 further kg feed does no longer impact piglet delivery weight.
- Giving further feed, further amino acids, and additional protein for overdue gestation additionally does no longer have any impact on delivery weight.
Opting for the optimum feeding technique right through gestation to succeed in uniform sows at farrowing will give a contribution to more straightforward control and luck within the farrowing unit. Then, you’ll produce robust, necessary piglets and make sure a excellent sow once more on the subsequent farrowing.
