“…Loss of piglets from birth to weaning is considered an important one, either as a result of infectious diseases or nonpathogenic causes, therefore monitoring of piglets allows its optimization. Munsterhjelm et al (2006), Andersen et al (2009) and Oliviero et al (2010) state that appropriate health programs in herds of sows minimize the losses of piglets a er birth. According to Rootwelt et al (2012) the loss of piglets from birth to weaning in problematic herds reaches 16.20%.…”

The aim of the study was to evaluate selected reproductive parameters in sows. Observed parameters were analysed in two herds with different health status. The experiment involved 160 hybrid sows from the 1st to the 5th litter (80 sows with health status A and 80 sows with health status B). Highly statistically significant differences (P ≤ 0.001) and significant differences (P ≤ 0.05) were found between the two groups in length of gravidity, total numbers of piglets, numbers of live-born piglets, numbers of stillborn piglets, numbers of reared piglets and losses of piglets per litter in favor of group B with declared health status. Evaluation of phenotypic correlation between the total number of piglets and the live-born piglets in the sows without declared health status revealed high positive correlation (P ≤ 0.01). Strong positive dependence was found also between the live-born and the reared piglets in this group. In the sows with declared health status, high positive correlation (P ≤ 0.01) was found also between the total number of piglets and the number of live-born piglets and between the number of live-born and reared piglets.

“…A greater concentration of IgG, total protein, ß2-and ^-globulin, and neutrophils registered at d 1 protect against neonatal infections. Under other managerial conditions, with greater infectious challenges, a difference in survival to weaning may therefore have been registered, although infections are not the most common cause of mortality on the first day of life (Munsterhjelm et al, 2006). Immunoglobulin G is commonly found in the ^ fraction at electrophoresis (Eckersall, 2008).…”

Improving survival is a continuous objective in swine breeding. The aim of this study was to record 22 blood variables and BW gain on the first day of life in Landrace-Yorkshire-Duroc crossbred piglets and to find associations between these variables and survival at weaning. All live piglets from 18 litters were weighed and blood sampled at birth and on d 1 and were monitored to weaning at the age of 5 wk. A total of 261 piglets were born, of which 8.8% were stillborn. Additionally, 15.1% died before weaning. The blood variables glucose, immunoglobulins, and white blood cells increased from birth to d 1 (P < 0.001), whereas α(1)- and β(1)-globulin, red blood cells, hemoglobin, and hematocrit decreased (P < 0.001). At birth, concentrations of lactate (P = 0.004), pH (P = 0.007), red blood cells (P = 0.017), hemoglobin (P = 0.018), and hematocrit (P = 0.052) were associated with survival to weaning. Also, concentrations of lactate increased (P = 0.030) and pH decreased (P < 0.001) when piglets were born in the last third of a litter. On d 1, concentrations of glucose (P = 0.015), hemoglobin (P = 0.025), and BW gain (P = 0.001) were all decreased in piglets that did not survive to weaning. Body weight gain also decreased (P = 0.005) when piglets were born in the last third of a litter. Concentrations of IgG on d 1 was not associated with survival at weaning (P = 0.230) but decreased (P < 0.001) when piglets were born in the last third of a litter. We conclude that several blood variables recorded at birth and on d 1 and BW gain on d 1 were highly associated with survival at weaning and that piglets born in the last third of the litter had less favorable vitality.

Use of repopulation for optimizing sow reproductive performance and piglet loss

The objective of this study was to analyse sow reproductive performance and piglet loss from birth to weaning before and after repopulation of a selected farm. The observation was carried out on a productive sow farm; 160 sows were included in the experiment. Before repopulation, 80 sows from the 1 st to the 5 th litter were evaluated. The original population of sows was removed. Repopulated (newly stocked) group consisted of 80 gilts at the 1 st litter. Newly delivered gilts with a status of minimum disease were placed into a decontaminated stable with a strict batch, black and white breeding system with stringent hygienic provisions. The piglets were weaned at the mean age of 28 ± 3 days. A very highly significant difference (P ≤ 0.001) in favour of the repopulated group of sows was found in the evaluation of the total number of piglets, the number of live-born piglets and the number of stillborn piglets in %; a significant difference (P ≤ 0.05) in favour of the repopulated group of sows was found in the number of stillborn piglets. In reared piglets and losses of piglets, both in numbers and percentage, a highly significant difference (P ≤ 0.001) was found in favour of the repopulated group. This study brings important information on the benefits of repopulation pig breeding.Diseases, health of pigs, rearing, reproduction traits, status with minimum disease
