DOI: 10.1007/s00484-024-02792-5
Abstract: Heat stress in hyper-prolific lactating sows is recognised as a factor reducing feed intake, milk production, and welfare, with significant losses in farm productivity. Individual capacities for body thermoregulation during environmental hyperthermia determine the adaptation… read more here.

DOI: 10.1093/jas/skaa054.165
Abstract: The objective was to determine phosphorus (P) requirement of lactating sows using 24-hour urinary P excretion as the response criteria. The underlying assumption was that urinary P remains low and constant until the requirements are… read more here.

DOI: 10.1093/jas/skaa261
Abstract: The present study investigated the effect of optimizing the total dietary arginine-to-lysine ratios on metabolism of lactating sows and piglet performance by supplementation with L-arginine (Arg) during lactation. A total of 200 multiparous sows (3… read more here.

DOI: 10.1093/jas/skac222
Abstract: Abstract Precision feeding (PF) aims to provide the right amount of nutrients at the right time for each animal. Lactating sows generally receive the same diet, which either results in insufficient supply and body reserve… read more here.

DOI: 10.1093/jas/skad129
Abstract: An accurate understanding of heat stress (HS) temperatures and phenotypes that indicate HS tolerance is necessary to improve swine HS resilience. Therefore, the study objectives were 1) to identify phenotypes indicative of HS tolerance, and… read more here.

DOI: 10.1093/jas/skae102.038
Abstract: Farrowing facility macroenvironment temperatures (TMacro) are often maintained at the upper end of the thermoneutral zone (24–25°C) of lactating sows, which may result in heat stress and reduced milk quality and quantity. Therefore, the study… read more here.

DOI: 10.1093/jas/skae102.353
Abstract: Optimal dietary phosphorus (P) is important for sows, not only to maintain P homeostasis and prevent premature culling due to lameness and locomotion, but also to support growth of their offspring. The objective of this… read more here.
