    ​​​​​​​Hélène Quesnel, INRAE, Saint-Gilles, France

    Hélène Quesnel is a senior scientist at INRAE, in France. INRAE was created in 2020 by merging INRA (the National Institute for Agronomic Research) and IRSTEA (the National Research Institute of Science and Technology for the Environment and Agriculture). Hélène Quesnel specialized in reproduction and lactation physiology in swine. Since 2006, she has worked on the nutritional, hormonal, and environmental effects on colostrum and colostrogenesis in sows and on the impacts of colostrum, in terms of quantity and composition, on the survival, growth and health of the piglets. The purpose of her research is to reduce the mortality and morbidity of piglets through the management of pregnant and lactating sows.​​​
    Roles of colostrum in piglet performance
    Piglets are born with very low energy reserves, without immune protection and with a rather immature gastrointestinal tract. Colostrum provides the piglet with energy for heat production and metabolism, passive immunity to help prevent infections, and growth factors that stimulate growth and maturation of tissues and organs. Colostrum, thus, is essential in ensuring piglet survival within the few days after birth and health and growth until weaning. Long-term effects on growth and mortality were also reported. Both colostrum yield and composition are highly variable among sows. In this review, a focus is made on the immune quality of colostrum, and especially on the impact of maternal feeding. Various ingredients that presumably have immuno-modulating effects (such as fish oil, prebiotics and probiotics) increased concentrations of immunoglobulins G, A and (or) M in sow colostrum when they were provided during the last weeks of gestation.

    ​​​​​​​Peter Kappel Theil,  Aarhus University, Denmark.

    Peter Kappel Theil is professor at Department of Animal Science, Aarhus University, Denmark. Dr. Theil’s research focus on improving sow productivity, piglet survival and piglet growth and major attention is paid to impact of nutrition of sows during gestation, transition and lactation. His research projects benefit the pig industry and are typically carried out in collaboration with partners within the swine industry including private feedstuff companies. Other academic activities include teaching and supervision of students, oral presentations, opponent at examinations, reviewer of scientific papers and research proposals, leader of the thematic group “monogastric nutrition and physiology” at Aarhus University and member of the Danish National Board for Nutrient recommendations for pigs. 

    Importance of sow feeding and nutrition on farrowing performance and colostrum production

    The transition from late gestation into early lactation is crucial for sow productivity because the majority of piglet mortality occur during or within 1-2 days after farrowing. Piglet mortality is caused both by stillbirths and by neonatal mortality, and therefore the farrowing process and the colostrum production are key aspects for achieving success in the farrowing unit. Proper nutrition in late gestation and around farrowing is important for improving the farrowing process and the sow colostrum production, and optimal feed supply and feed composition is of paramount importance for minimizing piglet mortality.The talk will provide state of the art knowledge within colostrum formation and how nutrition of late gestating sows affects the farrowing dynamics and colostrum production.

    Importance of the first hours and weeks on piglets life : from colostrum to creep feed

    A good start in life is crucial for piglets health and performances, especially with hyperprolific sows and demedication. The piglet is born with low energy stores and devoid of immune protection. Colostrum provides energy and maternal immunoglobulins. Therefore, the immune quality of colostrum is very important for the piglet immune system. By measuring its quality and improving the content of immunoglobulins, it enhances piglet immune system development. Moreover, its immune system is challenged by stresses during weaning period. At the same time, the quantity of maternal immunoglobulins decreases, and the piglet starts to produce its own immunoglobulins. By receiving enough milk and a good quality creep feed, the consequences of weaning stresses are reduced and the immune system is stronger. The speech will provide information on how to measure immune quality of colostrum, how to improve it and explain why creep feed is important.
