Comparable cortisol, heart rate and milk let-down in nurse sows and non-nurse sows [PDF]
Livestock Science, 2017 Increasing litter size in hyperprolific sows has led to the need for management systems for surplus piglets, one of which is the use of nurse sows. The aim of this study was to investigate physiological changes in salivary cortisol, heart rate and number

Effect of supplementing sows with Solanum glaucophyllum, a natural source of calcitriol, on farrowing performance, piglet survival and litter performance [PDF]
, 2022 Survival of piglets until weaning is a major contributor to the rentability of pig production systems. Large litters are often associated with complications and prolongation of the farrowing duration causing piglet mortality.

Acta Veterinaria Scandinavica, 1970 Of a total of 31,766 pregnancies 465 abortions were reported, in average 1.46 %. By comparison of the frequency of abortion at different times of the year a significantly higher percentage of abortion was found in sows inseminated during the summer months. No significant difference was found between 68 boars as to the frequency of abortion.

Alternative farrowing systems: design criteria for farrowing systems based on the biological needs of sows and piglets [PDF]
, 2010 The construction of a suitable farrowing environment is a continuing dilemma: the piglet's needs must be matched with those of the sow and the farmer during the main phases that constitute farrowing: nest building, parturition and lactation. Difficulties
