COMPORTAMENTO ALIMENTAR DE FÊMEAS SUÍNAS EM LACTAÇÃO MANTIDAS EM AMBIENTE QUENTE

Food intake (CR) was evaluated in 36 females of 1st, 2nd, 3rd, ³4th birth order, in three stages of lactation (E1= from equalization to the 7th day; E2= 8-14th; E3= 15th to weaning), maintained in a hot environment, at morning, afternoon and night. The frequency and duration in which the sows remained standing in idle (OEP) or in activity at the feeder or fountain (PACB), were obtained on thee 17th day of lactation, evaluated in four periods of the day: P1= 6 p.m. to 12 a.m.; P2= 12 a.m. to 6 a.m.; P3= 6 a.m to 12 p.m. and P4= 12 p.m. to 6 p.m. Showed the interaction for CR, with smaller consumption for the primiparous in E1 in the afternoon period. The CR increased next to weaning (E3). The frequency and time of OEP were not modified. The females of 3rd birth used more time in PACB. The greater frequency and time used in this activity occurred between 6 a.m. to 6 p.m.
