A whelping box (also nesting box or whelping pen) is designed to protect puppies during birth (whelping) and early life by keeping them safely contained, protected from cold, and safe from the danger of crushing or smothering by the mother.

Most boxes will include a low railing (termed rails, pig rails, or roll-bars) fixed to the inside perimeter of the box.

Hmm- coś mi tu jednak nie pasuje...... Zresztą pig rail nie odnosi się do pig:) czy piglet:)

Attended Farrowings

Research indicates that attending and assisting at farrowing can increase piglet survival and the number of pigs weaned. By being present at farrowing, one can quickly identify disadvantaged piglets and begin to assist them. However, each producer should weigh carefully the costs and benefits of supervised farrowings. Having many litters to supervise at one time (through batch farrowing or continuous farrowing in a multiple farrowing room complex) makes more efficient use of labor.

Prevent Chilling

The farrowing quarters need to provide two different microclimates: a cool one for the sow (60-65°F) and a hot one for the newborn piglets (85-95°F the first few days, then decreased to the 70-80°F range). To achieve this goal, maintain a room temperature at approximately 65-70°F and provide zone heating for the litter.

Closely monitor the sow and litter’s responses to the zone heating to ensure their thermal needs are met. If the amount of heat provided by the zone heaters is excessive, piglets will move away from the heat source. This not only wastes power but can cause the sow to become too warm and increase piglet mortality. The thermal needs of piglets are met if they are lying in a prone position gently touching each other. If they are piled, attention should be given to providing more heat.

Provide zone heating in the farrowing quarters beginning 24 hours before expected farrowing. Heat lamps, heat pads, radiant heat devices, and hovers are common ways to provide zone heating in farrowing houses. Many times, however, the zone heating is placed only to the side of the sow in the creep area. Research indicates that having an additional heat lamp placed at the rear of the sow during farrowing reduces piglet mortality. The extra heat source assures the piglet of immediate warmth following birth. The key is to have the supplemental heat directed behind the sow before farrowing and until farrowing is completed. If there is no extra heat present behind the sow during farrowing, position disadvantaged piglets in a heated area immediately after birth.
