“…Miscellaneous disorders caused the second highest mortality and the main cause was crushing of new born by mother. Similar finding was also reported by Ramesh and Sivakumar (2007) and Edwards et al (1986). This can be explained by the fact that after farrowing in the side lie posture, the gilts stand up for a moment during the initial period and major movement of gilts occurs in pen more frequently than in crate because of availability of more space.…”

“…Weak and low weight piglets have much higher pre-weaning mortality than piglets of average weight (Edwards, Malkin and Spechter, 1986;Gardner, Hird and Franti, 1989), especially if they are born in large litters or in litters with great weight variation (English and Smith, 1975). Weak and low weight piglets have much higher pre-weaning mortality than piglets of average weight (Edwards, Malkin and Spechter, 1986;Gardner, Hird and Franti, 1989), especially if they are born in large litters or in litters with great weight variation (English and Smith, 1975).…”

Litter size and piglet performance. AbstractSixty gilts were allotted to one of the following feeding regimes: CR, a conventional diet offered at a restricted level according to Swedish feeding standards; SA, a simplified gestation diet (mainly oats and barley) offered at a restricted level and a conventional diet offered ad libitum during lactation; CA, a conventional gestation diet offered at a restricted level and the same diet offered ad libitum during lactation. The sows were followed for four parities. Piglet birth weight was unaffected by sow feeding, but differences in piglet live weight were found from 3 weeks of age to the end of the experiment when the piglets were 9 weeks old. CA piglets were heavier than SA piglets at 3 and 9 weeks of age and heavier than both CR and SA piglets at weaning (35 ± 3 days). Litter size was unaffected by treatment as was piglet mortality, whereas the cause of death varied with treatment. Mortality due to trauma was higher among CA piglets than among others, while mortality due to weakness was higher among SA piglets than others and there was also a tendency for higher mortality due to diarrhoea among CR piglets. It was concluded that the CA feeding regime was superior with regards to piglet performance.

“…One aim of the traditional farrowing crate, which has influenced its overall design, has been to restrict the sows' movement to reduce preweaning mortality attributable to crushing. An observation by Edwards and Malkin (1986) and Marchant et al (1996) showed that posterior crushing (when the sow changes from a standing to sitting position and traps piglets under her back legs) is one of two major movements performed by the sow that kills piglets. The other occurs when sows lie from a sitting position and piglets are trapped beneath her thorax.…”

Two hundred eighty-seven lactating Newsham sows and their litters were used to determine the effects of intensive indoor (n = 147) and intensive outdoor (n = 140) production systems on sow and litter productivity and behavior. All sows were of contemporary age and fed a completely balanced sorghum-based diet. Behavior data were collected by live observation on 40 sows and litters (20 indoor and 20 outdoor) using a 5-min scan sample over a 4-h period in the afternoon (1400 to 1800). The durations of lying (90.0 vs 72.1 +/- 2.76% of time observed) and drinking (4.42 vs 1.41 +/- 0.6% of time observed) were higher (P < 0.01) among indoor than among outdoor lactating sows. Nursing interval and feeding and sitting behaviors were not different (P > 0.05) between production systems. Piglets spent more (P < 0.05) time walking (10.1 vs 5.2 +/- 1.72% of time observed) and engaged in play activity (5.0 vs 1.7 +/- 1.26% of time observed) when housed outdoors than indoors. Outdoor piglets had more (P < 0.05) nursing behaviors directed toward the sow (27.5 vs 20.3 +/- 2.02% of time observed) but time spent in contact with the sow did not differ between environments (38.8 vs 39.2 +/- 2.78% of time observed). Treatments did not influence (P > 0.05) any of the sow or piglet production parameters. In conclusion, outdoor-kept Newsham sows and their piglets showed a richer behavioral repertoire, but the diverse environments did not influence production parameters.
