| Popis: | The present study investigated the litter performance of multiparous sows had different feeding frequencies during summer season. A total of 60 crossbred multiparous sows was allotted to one of two treatments based on body weight (BW) according to a completely randomized design. Two different feeding frequencies based on NRC (National Research Council) were applied as conventional feeding (T1; 2 kg per meal at 06:00, 11:00, and 17:00) and night feeding (T2; 1.5 kg per meal at 06:00, 11:00, 17:00, and 2 kg at 22:00). Sows in T2 treatment had lower (p < 0.05) BW changes during lactation. The backfat thickness change of sows was decreased in T2 treatment during lactation (p < 0.05). The daily feed intake differed significantly between T1 and T2 with increased feed intake of the T2 group at 5.47 kg/d to 5.14 kg/d in the T1 group (p < 0.05). There was a significant difference in total weight of weaned piglets between T1 (70.50 kg) and T2 (74.34 kg). A greater total litter weight gain was observed in sows in T2 treatment. Night feeding is suggested for lactating sows with significant beneficial effects on litter growth during summer season. |
