Sažetak
The aim of the study was to compare and analyze the effect of isotonic protein drink (IPD) on pre-weaning mortality (PWM) and number of weaned piglets (NW) per litter. The study was carried out in commercial conditions on 36 litters of F1 offspring generation of hyperprolific line of Landrace x Large White cross sows, with 18 litters in the experimental group (EX) and control group (CG) each. On postpartum day 2, litters in the EX and CG groups were equalized according to management procedure and monitored for four weeks of suckling. Statistical analysis was performed by GLM procedure with the following parameters included in the model of calculation: Gender (G, ≤5 or ≥7 male piglets per litter), Parity Order (PO, primiparae, secundiparae and multiparae) and Number of Born Alive piglets (≤12 or ≥13 born alive piglets per litter), including the farm PWM of 11.2% in the model. Values were expressed as least squares mean ± standard error (LSM±SE). On day 2 of equalization, the mean number of piglets per litter was 12.02±0.09 in the EX group vs. 12.03±0.09 in the CG group. Upon weaning, the mean NW per litter in the EX and CG group was 11.65±0.23 and 10.85±0.22, respectively. Significant between-group difference (P=0.02) was found in the number of weaned piglets. PWM percentage was lower in the EX group (5.07%) as compared with CG (9.22%), which was significantly lower than the average PWM recorded on the farm. The mentioned differences may also be in part attributed to closer monitoring of the groups during the trial. These preliminary results pointed to the favorable effect of IPD including a significantly lower PWM rate in the EX group relative to the farm average rate, as well as 45% reduction in PWM as compared to CG group. Further analyses with more litters and higher piglet load per sow during suckling period will provide new information on the effect of IPD on NW per litter and PWM in piglets.
