Surveys of PWM on commercial units have suggested that two major predisposing factors are low birth weight and low body temperatures in the early period after birth.
You may need to download version 2.0 now from the Drying piglets at birth with a desiccant or warming them in a warming box (at 96 to 100oF) for 30 minutes were equally effective at minimizing the magnitude of piglet body temperature decline after birth. Low post-natal body temperature is a predisposing factor for piglet mortality. Recent research has demonstrated that mean body temperature reductions of 4.4°C … The piglet has no brown fat (used by mammals to generate heat quickly) so the piglet cannot use fat to generate heat in cold conditions.
A part of Pork Checkoff’s sow-lifetime productivity project, these studies confirmed that all piglets experience a significant decrease in body temperature after birth. This research project was carried out to develop an understanding of the effect of piglet birth weight on changes in rectal temperature after birth, and to evaluate practical approaches (namely drying, warming, or oxygenation) that could be applied at birth to mitigate this risk and increase piglet survival under commercial conditions.
Piglets are born without any antibody protection, their bodies contain fat energy for about one day of life, and they cannot regulate internal body temperature well until they are a few days old.
Increases in litter size are associated with a decrease in average piglet birth weight and, particularly, an increase in the number of low birth weight piglets (i.e., piglets weighing less than ~2.2lb at birth).

Piglets require environmental temperatures of 34°C or more for the single neonate, or 25-30°C or more for the piglet able to huddle in order to maintain body temperature. European project to help limit antibiotic use in pig production. Available now from 5mBooks.com. Over recent years, both litter size at birth and pre-weaning mortality (PWM) have increased significantly in US commercial swine herds.
Six studies were carried out under typical farrowing house conditions involving a total of 1,032 sows and 13,208 piglets.Javascript must be enabled for the correct page display Husbandry.
Temperature recording from the rectum. Another way to prevent getting this page in the future is to use Privacy Pass. Thus, anything that may lead to a reduction in milk production or consumption, such as chilling or exposure to disease organisms, compromises the health and well-being of newborn piglets. This study investigated the effect of birth weight on piglet body temperature over 24 h after birth under typical conditions. Latest articles. However, the combination of drying and warming of piglets at birth was more effective in this regard than using either approach independently. These two factors are related; low birth weight piglets exhibit the greatest temperature decline early after birth and have the highest level of PWM. On-farm procedures. 29 Jul 2020. Normal body temperature is between 101 and 103 degrees Fahrenheit (38.3 and 39.4 degrees Celsius).
The body temperature change can reflect the health status change of the pig in time.
