The objective of the present study was to quantify the associations between climate data and
either weaning-to-first-mating interval (WMI) or adjusted 21-day litter weights of sows during …

The objectives of this study were to determine the associations between climatic factors and
production factors for returns to service of female pigs during summer and to quantify the …

The objective of this study was to examine interactions between climatic factors, parity, and
weaning-to-first-mating interval (WMI) for total number of pigs born at subsequent parity …

The objective of the present study was to quantify the associations between age at first
mating (AFM) in gilts and the climatic factors of photoperiod (PP; h), number of hot days (HD) …

The aim of this study was to examine the respective associations between farrowing rate
and either environmental or production factors in female pigs in commercial herds. We …

Heat stress is known to influence sow reproduction, but it is unknown to which extent under
temperate climates. Therefore, the impact of temperature and temperature‐humidity index …

Context Large-scale genetic evaluation is promising for efficiently improving sow lifetime
productivity, and therefore, a reasonable operational model should be pursued to analyse …

The objective of the present study was to retrospectively investigate causes of variation on
litter size at birth (total number of piglets born per litter (TB) and number of piglets born alive …

High temperature is an environmental factor that impairs sow fertility. In this study, we
identified the critical weeks for heat stress effects on aspects of fertility performance, namely …

ABSTRACT A total of 179 lactations obtained on 71 multiparous sows [30 Creole (CR) and
41 Large White (LW)] between June 2001 and July 2004 were used to determine effects of …
