“…Our results did not show any significant difference in piglet serum immunoglobulins between S and L piglets at birth or over time. Conversely, Schnier et al [ 32 ] reported numerically lower immunocrit values in S piglets compared to L piglets. On the other hand, Morton et al [ 33 ] reported that piglet birth weight did not affect serum immunocrit values, which is in line with our results.…”

We studied the fecal lactobacilli count and species diversity of growing pigs along with immune parameters associated with intestinal lactobacilli. Thirty pigs categorized as small (S, n = 12) or large (L, n = 18) at birth were followed from birth to slaughter in two commercial herds, H1 and H2. Herds differed in terms of their general management. We determined sow colostrum quality, colostrum intake, piglet serum immunoglobulins, and pig growth. We took individual fecal samples from pigs in the weaning and finishing units. We studied lactobacilli count and identified their diversity with 16S PCR. Total lactobacilli count increased in H1 and decreased in H2 between samplings. Lactobacilli species diversity was higher in H1 in both fecal sampling points, whereas diversity decreased over time in both herds. We identified altogether seven lactobacilli species with a maximum of five (one to five) species in one herd. However, a relatively large proportion of lactobacilli remained unidentified with the used sequencing technique. Small pigs had higher lactobacilli counts in both herds but the difference was significant only in H2 (p = 0.01). Colostrum quality was numerically better in H1 than in H2, where colostrum intake tended to be associated with total lactobacilli count (p = 0.05).

“…The selection was focussed on clinical variables that can be assessed easily by farmers and resulted in body weight, rectal temperature, crown-rump-length, a vitality score and an IUGR score. As clinical variables are often estimated being “subjective” compared to “objective” laboratory parameter, additionally a set of laboratory measurements was selected, expected to be appropriate in predicting the death of a newborn piglet [ 34 – 36 ].…”

Killing underweighted low viable newborn piglets: Which health parameters are appropriate to make a decision?

Background The aim of this study was to estimate the mortality risk and associated factors within the first days of life for underweight or low-vital neonatal piglets. This risk estimation should start a discussion concerning the preconditions for timely killing of compromised newborn piglets to prevent unnecessary pain and suffering. In an observational study, various clinical and laboratory variables were examined in 529 piglets out of four farms. Body weight, crown-rump-length, rectal temperature, a 4-stage vitality score, an intrauterine-growth-retardation score, glucose, lactate, haemoglobin and immunocrit were assessed on the first day of life. Vitality was scored by three factors: movement, abdominal palpation, and colour of the skin. Afterwards the death of the piglets (by killing or spontaneously) was monitored until day 5 of age. Results Body weight, rectal temperature and vitality score were significantly associated with probability of death. Piglets with rectal temperatures ≤ 37.5 °C, a body weight < 0.86 kg and impaired vitality scores were found to have the highest probability of death until day 5 of age. Conclusion The clinical findings, identified by this model, allow a first estimation of mortality risk for newborn piglets within the first days of life. In a further step veterinarians, farmers and ethicians now need to clarify what probability of death should justifiy the killing of a newborn piglet.

Background The aim of this study was to estimate the mortality risk within the first days of life for underweight or low-vital neonatal piglets. This risk estimation should start a discussion concerning the pre-conditions for the killing of compromised new-born piglets for the prevention of unnecessary pain and suffering. In a field study, various clinical and laboratory variables were examined in 529 piglets out of four farms. Body weight, crown-rump-length, rectal temperature, a 4-stage vitality score, an intrauterine-growth-retardation score, glucose, lactate, haemoglobin and immunocrit were assessed on the first day of life. Vitality was scored by three factors: movement, abdominal palpation and colour of the skin. Afterwards death or survival of the piglets was monitored up until the fifth day of age. Results Body weight, crown-rump-length, rectal temperature, vitality score, IUGR-score, glucose and immunocrit were significantly associated with the probability of death (univariate model, p = < 0.0001). The final predictive multivariate model comprised the factors body weight, rectal temperature and vitality score. Piglets with a rectal temperature ≤ 37.5°C and moderate vitality score were found to have the highest probability to die until day 5 of age. Conclusion The clinical findings, identified by this model, allow the estimation of mortality risk for a new-born piglet within the first days of life. In a further analysis veterinarians, farmers and ethics need to clarify which probability of death justifies the killing of a new-born piglet.
