“…Overall, SP outperformed GP during the pre-weaning period, as reflected in their heavier weights and faster growth, which agrees with numerous studies [3,11,[38][39][40][41]. The poorer growth of GP has been attributed to a variety of factors such as reduced milk yield [21,42], reduced passive immunity in the perinatal period, and poor growth and development in the pre-weaning period [25].…”

Feeding fibre and branched-chain amino acids (BCAA) to sows during late gestation and lactation, respectively, have been shown to improve litter weights at weaning. Therefore, supplementing primiparous sow diets with lucerne chaff, a feedstuff high in fibre, BCAA and tryptophan, may improve the performance of their progeny. Experiment 1 investigated the effects of feeding primiparous sows (n = 118) either (i) a control diet (CON); (ii) CON with 1 kg of lucerne chaff (LUC); or (iii) a diet formulated to have a similar digestible energy and BCAA content as CON + LUC (SIMLUC 1) until farrowing. The LUC and SIMLUC 1 diets improved day 21 litter weight (p = 0.055). In Experiment 2 primiparous (n = 111) and multiparous sows (parities 2–5, n = 112) were fed either the CON or SIMLUC diet (SIMLUC 2) from day 110 of gestation to farrowing (PreF), or to day 10 post-farrowing (PreF + PostF). The SIMLUC 2 diet tended to be more beneficial to primiparous compared to multiparous sows when fed PreF, as indicated by an interaction between diet and parity on day 21 average piglet weights (p = 0.078). Overall, SIMLUC is most effective in improving primiparous progeny performance as evidenced by their D21 weights.

“…It is also possible that there is reduced gastrointestinal permeability in gilt progeny compared to sow progeny [32], limiting their ability to absorb certain components within colostrum and (or) milk. Restriction of fetal growth in late gestation may be responsible for a reduction in development of gastrointestinal tissue and skeletal muscle in neonatal gilt progeny [33,34], and these differences have been shown to persist up to weaning [33,35]. Colostrum production may be affected by number and size of mammary cells [16] and therefore may be compromised in primiparous sows.…”

It is important to understand the biological factors influencing the poorer lifetime performance of gilt progeny in comparison to sow progeny and determine whether this may be partially due to differences in lactation performance between primiparous and multiparous sows. It was hypothesized that primiparous sows would have lower levels of immunoglobulin G (IgG) in colostrum and milk compared to multiparous sows, and lower levels of other energetic components. Differences in colostrum and milk composition between ten primiparous and ten multiparous sows (parities 3 and 4) from a commercial herd were examined throughout lactation (day 0, 1, 2, 3, 7, 14, and 21). Overall, there were no (p ≥ 0.05) parity differences in total IgG, fat, protein, lactose, and net energy (NE) concentrations. Primiparous sows had higher lactose levels at day 2 (parity by timepoint interaction; p = 0.036) and lower NE at day 3 (p = 0.091), and multiparous sows had higher lactose levels at days 14 and 21. Results suggest that shortcomings of gilt progeny are unlikely due to insufficient nutrient levels in colostrum and milk, and more likely to reduced colostrum and milk intake and their capacity to digest and absorb each component.

“…After weaning, however, environmental factors appear to prevail and account for the differences in ADG and ADG-CV observed in the present study. Nevertheless, it cannot be ruled out that factors related to parity, such as the ones affecting gastrointestinal morphology (Alvarenga et al, 2013) and muscle fiber development (Silva et al, 2013), may not impair the postnatal performance of piglets.…”

“…Among the causes of low birthweight and high withinlitter heterogeneity, sow parity is of particular interest. The physiological differences between low-and high-parity sows are known to affect piglet prenatal development (Foxcroft and Town, 2004;Silva et al, 2013). However, the impact of parity on piglet postnatal development, mortality rates, and carcass traits is not well understood.…”

Impact of piglet birthweight and sow parity on mortality rates, growth performance, and carcass traits in pigs

et al. 2017

A total of 5502 piglets from 435 sows were selected for evaluation of the effect of piglet birthweight and sow parity on mortality rate (MR), growth performance, and carcass traits in pigs. Piglets were distributed into one of eight categories according to their weight (<600, g) and sows were classified according to parity (1-5). The maximum MR during lactation (day 0 to day 21) was found in category <600 g, whereas the lowest was observed in categories ≥1401 g. Pigs with greater body weight (BW) at birth were equivalently greater until 59 days of age. Average daily weight gain (ADG) was improved by increasing piglet birthweight between 0 and 21 days as indicated by a linear regression effect. After weaning, this effect was reduced up to 168 days, indicated by a quadratic, as opposed to linear, regression effect. The increase in growth rates corresponded to improved lean meat content and hot carcass weight. Increasing sow parity corresponded to a quadratic improvement of BW and ADG during lactation, but not after weaning. However, the improved pre-weaning performance was concomitant with a linear increase of within-litter BW and ADG variation. No effect of parity was observed on carcass traits. Piglet birthweight and sow parity influence litter postnatal development, mainly during early life. After weaning, these effects are less evident with a minor impact on carcass traits.
