Resumen
The objective of this trial was to evaluate the behavioral patterns and performance of lactating sows and
their litters under the effect of artificial vocalization. Twenty-eight sows and their litters were distributed
in a completely randomized design in a 2x2 factorial scheme (artificial vocalization x lactation week). The
behavior of the animals was monitored during 24 hours on the 7th and 15th days of lactation, analyzing the
number, interval, and frequency of nursings. The body condition and performance of the sows were also
evaluated. Artificial vocalization promoted higher frequencies of eating for sow and nursing for piglets (P
<0.05), increased inactive sow behavior (P <0.05), and reduced sow alert in activity (P <0.05). The number
and duration of suckling sessions at the 15thday of lactation were reduced (P <0.05). The use of artificial
vocalization did not affect the body condition or milk production of the lactating sows, or the performance
of the litter during lactation (P> 0.05). The use of maternal artificial vocalization during lactation of sows
promoted greater lactation efficiency and longer rest time, favoring the sows’ welfare.
