Microwave radiation (2.45 GHz) was examined as a heat source for rewarming chilled neonatal piglets. A multi-mode cavity (60 x 60 x 60 cm) was constructed of 22 gauge perforated galvanized steel. The radiation applicator was a slotted waveguide, 70 cm in length, which was located centrally 46.5 cm a...
Effects of increasing the frequency of suckling, induced by maternal vocalizations, on the live weight of piglets. / Determinación del efecto de una mayor frecuencia de amamantamiento, inducido por vocalizaciones maternas, sobre el peso de cerdos lechones hasta el destete
The objective of this study was to determine if using maternal sounds, at a higher frequency, associated with lactation, would indirectly influence milk production by the sow, thus increasing litter weight. The litters of 36 crossbred sows were allocated into 4 experimental groups. The study was div...
