“…The quantity of colostrum supply was estimated by indirect measurement of serum Ig concentration using the immunocrit ratio of the piglets in the first 24 h post-partum [24]. The results of the immunocrit ratio in our study were in the range of 0.167-0.193 in the CON group and 0.157-0.203 in the RYE group.…”

A sustainable increase in livestock productivity cannot be achieved without the use of sustainable animal feed. Due to the growing awareness of the long-term benefits of sustainability, there is an increasing interest in replacing traditional feed resources with the most sustainable feedstuffs in pig production. Rye production is relatively sustainable compared to wheat. This farm study investigated whether the newborn body weight as well as antibody transfer in piglets (serum immunoglobulin immunocrit) are affected by feeding rye instead of wheat grain to transition sows. A total of 237 sows and their piglets (n = 711) from three farms located in northern Germany participated in this study. During the transition period, the sows were fed either a wheat-based diet used as the control diet (CON) or a 30% rye diet (RYE) for 7 days before the calculated farrowing date. On the day of farrowing, piglet body weights within 24 h post-natal (PN) were recorded, and blood samples were taken from the lightest, medium, and heaviest piglets in each litter to determine the quantification of immunoglobulins in the piglets. Feeding rye-based diets to the sows showed no differences in the body weight of the newborns (within 24 h) compared to the CON group in all body weight categories, except on Farm C in light and medium piglets, where high BW were observed in the CON group. The immunocrit ratio did not show any differences between both feeding groups. A relationship between newborn body weight and immunocrit ratios in the CON and the RYE groups was observed only on farm A. Overall, this study showed that including amounts of rye up to 30% in sows’ diets during the transition period had no negative effects on newborn piglet body weight or on antibody transfer and therefore can be considered an adequate replacement for wheat (up to 30%) in diets for transition sows. However, future research is needed to determine whether a higher proportion of rye may be used.

“…Therefore, the survival rate of piglets is positively correlated with the concentrations of Ig in plasma, particularly IgG [22]. Consequently, the measurement of the level of piglet serum Ig immunocrit could be used as an indicator of both sow colostrum production and the suckling ability of the piglets [23,24].…”

Background The immunocrit is a cost-effective and straightforward technique traditionally used to assess passive immunity transfer to newborn piglets. However, it has not been previously used for monitoring the effect of vaccination and/or infections. Therefore, this study aimed to evaluate the usefulness of the immunocrit technique as an immunological monitoring tool in a vaccination and challenge scenario, using porcine circovirus 2 (PCV-2) as pathogen model. The immunocrit ratio was monitored in PCV-2 vaccinated (V) and non-vaccinated (NV) 3-week-old piglets (study day 0, SD0) that were subsequently challenged with this virus at SD21 and followed up to SD42. Additional techniques (PCV-2 IgG ELISA, optical refractometry, and proteinogram) were performed to further characterize the results of the immunocrit analysis. Results Immunocrit, γ-globulin concentration and PCV-2 S/P values followed similar dynamics: descending after PCV-2 vaccination but ascending after an experimental PCV-2 inoculation. However, statistically significant differences between V and NV animals were only found with the PCV-2 ELISA. In this case, V animals had significantly higher (p < 0.05) S/P values (S/P ratio = 0.74) than NV (S/P ratio = 0.39) pigs only after challenge at SD42. On the other hand, serum total protein obtained by refractometer (STPr) were maintained from SD0 to SD21 and increased in both groups from SD21 to SD42. Correlations between techniques were low to moderate, being the most robust ones found between immunocrit and optical refractometry (ρ = 0.41) and immunocrit with γ-globulins (ρ = 0.39). In a subset of sera, the proteinogram technique was applied to the whole serum and the supernatant of the immunocrit, with the objective to characterize indirectly the immunocrit fraction. The latter one included all protein types detectable through the proteinogram, with percentages varying between 64.3% (γ-globulins) and 82% (β-globulins). Conclusion The immunocrit technique represented a fraction of the total serum proteins, with low to moderate correlation with all the complementary techniques measured in this study. Its determination at different time points did not allow monitoring the effect of vaccination and/or infection using PCV-2 as a pathogen model.
