Seasonal influences on the litter size at birth of pigs are more pronounced in the gilt than sow litters
TL;DR: In this paper, the authors used data from herds to demonstrate the degree of seasonal influence on litter size at birth in gilts compared to sow parities 2, 3-5 and older (parities ⩾6) in a conventional, open-housing system for commercial pig herds in the northeastern part of Thailand.
Journal ArticleDOI
Weaning-to-service interval in primiparous sows and its relationship with longevity and piglet production
Wichai Tantasuparuk,Wichai Tantasuparuk,Nils Lundeheim,A.-M Dalin,Annop Kunavongkrit,S. Einarsson +5 more
TL;DR: The relationship between weaning-to-service interval (WSI) in first parity sows and longevity, including lifetime piglet production until parity eight were studied, and stayability variables, describing if the sow had farrowed her 2nd to 8th litter, were analysed.
Journal ArticleDOI
The association between growth rate, body weight, backfat thickness and age at first observed oestrus in crossbred Landrace × Yorkshire gilts
TL;DR: It is indicated that replacement gilts with a high GR (both GRe and GRs) tend to show sign of oestrus earlier than gilt with a low GR ( both G reand GRs), which is also seen in crossbred Landrace x Yorkshire Replacement gilts in the tropics.
Journal ArticleDOI
Influence of repeat-service and weaning-to-first-service interval on farrowing proportion of gilts and sows
TL;DR: It is concluded that repeat-service in gilts/sows resulted in a 12.5% decrease in farrowing proportion, and sows returning to oestrus later than 6 days after weaning had 7% lower FP than sows mated within 6 days of weaning.
Journal ArticleDOI
Effects of lactation length and weaning-to-service interval on subsequent farrowing rate and litter size in Landrace and Yorkshire sows in Thailand
Wichai Tantasuparuk,Wichai Tantasuparuk,Nils Lundeheim,A.-M. Dalin,Annop Kunavongkrit,Stig Einarsson +5 more
TL;DR: The aim of the present study was to investigate the influence of lactation length (LL) on weaning-to-service interval (WSI), and the effect of LL and WSI on the subsequent farrowing rate and litter size among purebred Landrace and Yorkshire sows under tropical conditions.
