چکیده
Abstract The objective was to evaluate the impact of sow location, within farrowing room, on reproduction during periods heat stress. Data were collected 1,866 sows at a 3,600-sow commercial farm in eastern North Carolina from May August 2021. In buildings, evaporative cool cell pads cooled air entering hallway. Cooled air, hallway, then entered rooms through inlets front room and pulled by fans back room. For data analysis, each divided into four zones. Zone 1 included near letting air. 4 where exited building embedded wall. Zones 2 3 intermediate. Each housed between 18 36 sows. After farrowing, had ad libitum access lactation diet. Traits piglet survival (number weaned ÷ total number born) percentage conceiving 7 days after weaning, subsequent born, born alive, stillborns, caliper score prefarrow, weaning loss. Results are shown Table 1. Piglet greater (P < 0.05) for that farrowed inlets. Similarly, litter weight heavier relative part conceived farrowed, linearly associated with zone. Sows lost less body condition more piglets showed condition, survival, weights likely be rebred conceive

The effect of farrowing crate heat lamp location on sow and pig patterns of lying and pig survival.
Three experiments were conducted to study sow and pig behavior during the 1st 3 d after birth and pig survival during the 1st 2 wk after farrowing. In Exp. 1, 23 sows were housed in conventional farrowing crates that were divided into five sections: a .5- x 1.5-m front creep section and the remaining area divided into four sections, .75 x 1.05 m each. Air temperature was maintained at 19 degree...
متن کاملEffects of heat stress on mammalian reproduction.
Heat stress can have large effects on most aspects of reproductive function in mammals. These include disruptions in spermatogenesis and oocyte development, oocyte maturation, early embryonic development, foetal and placental growth and lactation. These deleterious effects of heat stress are the result of either the hyperthermia associated with heat stress or the physiological adjustments made ...
متن کاملHeat stress effects on farrowing rate in sows: genetic parameter estimation using within-line and crossbred models.
The pork supply chain values steady and undisturbed piglet production. Fertilization and maintaining gestation in warm and hot climates is a challenge that can be potentially improved by selection. The objective of this study was to estimate 1) genetic variation for farrowing rate of sows in 2 dam lines and their reciprocal cross; 2) genetic variation for farrowing rate heat tolerance, which ca...
