To prevent piglets losses during lactation Logo Feedia

Societals concerns about pig production impact major evolutions on farm: massive reduction of restraint (free-farrowing sows, exterior access), reduction of losses during lactation, stop of mutilations (tail docking, castration), reduction of antibiotics use…

In the same time, genetic progress on sow prolificity has reduced average piglet birth weight and litter quality. To this, colostrum intake is lower for each piglet, meaning smaller piglets and more sensitive to pathologies and non optimised performance.


To enhance piglets robustness 

In utero and soon as the farrowing, sows transfer their metabolic health to piglets : their microbiota, their oxidative status and their immunity. So, in the first hours after birth, colostrum is essential for surviving, its contributes to piglets energy, immunity and vitality. This is essential for developing their own immunity The increase of piglets number and heterogeneity in the litter, encourage the competition between piglets to get access to teats : smaller, more fragile and less vigorous piglets have difficulties to get access to udders.

Combining plant extracts known for their immunomodulating and regulating actions on inflammatory-type responses, Imun'up has been created to enhance piglets robustness.
Specific ingredients of Imun’Up contribute to influence the immune system of sows and piglets. With a colostrum of better quality, Imun'up prepares piglets at weaning without medication.

2 ways of actions :

  • Inflammatory route with a modulation of the non-specific response, meaning local inflammation with swelling, redness, heat
  • Immunogenic route with the increasing of the specific immune response, meaning a better response of humoral and cellular mediation (antibodies, cytotoxic killer cells)

With these two ways, IMUN’UP permits to increase passive and active piglet immunity by an enhancement of sow immunity and to reduce the immunity gap where immune security is lower.

Act on sow and piglets

Nutritionist experts of Feedia advise a IMUN’UP incorporation at 2 kg/T of peri partum feed to have an action on colostrum quality or at 1 kg/T of lactating feed. To continue the enhancement of immunity program, IMUN’UP is recommended [1]  at 2 kg/T of prestarter feed and at 1 kg/T of starter feed.

Imun’up efficacy is visible by his contribution to increase sows colostrum quality. Indeed, on average, colostrum IgG concentration from sampled sows is 15% higher with Imun’up than the control group. This immune quality improvement is for all sows, primiparous and multiparous.

This colostrum quality improvement generates a better litter quality. Imu'nup contributes to reduce the number of piglets dead before 48 hours after farrowing and also the number of crushed piglets

Feed to piglets, IMUN’UP contributes to enhance piglet robustness. Trials results show an increase of growth performance with IMUN’UP. Indeed, piglets have a better daily feed intake and average daily gain without degradation of the FCR (*Feed Conversion Ratio), meaning a potential gain of 1,5kgs at the end of the starter phase.

These actions to fix losses in the lactating period are not exhaustive. Other factors, such as parity, genetic, air circulation, feed system, can be key factors in breeding success. Softwares, nutritional recommendations, and technical skills exist to respond to these needs.
