“…On the other hand, the duration of farrowing is positively correlated with a large litter size [13], resulting in an increase in the number of stillborn piglets primarily due to perinatal asphyxia [14]. Researchers and practitioners have continuously studied and implemented mechanisms to mitigate these effects, enhancing the nutritional intake and the productive and reproductive indices of gilts or sows in intensive production systems [15]. Nutrient intake during gestation greatly influences reproductive performance and the release of reproductive hormones in sows [16].…”

The late gestation period is crucial for fetal growth and development, impacting swine enterprises’ profitability. Various nutritional strategies have been explored to enhance reproductive performance in sows, but findings regarding birth weight and litter size have been inconsistent. This study investigated the effects of increased feeding allowance during the late gestation period on the reproductive performance and farrowing behavior of primiparous and multiparous sows. A total of 28 sows (Landrace × Yorkshire) were used in this experiment, and fed 2.50 kg/d or 3.50 kg/d from 84 days of gestation until farrowing. Farrowing behavior was monitored using a DeepEyesTM M3SEN camera. The data were analyzed using the 2 × 2 factorial within Statistical Analysis System (SAS, 2011, Version 9.3) software. The results indicated that regardless of the parity number, sows fed a high diet exhibited a numerical increase in the total number of born piglets and a significant increase in milk yield (p = 0.014) and piglet birthweight (p = 0.023). Backfat thickness loss was significantly higher in sows with a 2.50 kg feeding allowance (p = 0.022), and the total number of piglets born, live births, and litter size were numerically higher in sows fed 3.50 kg per day. Moreover, stillborn piglets, mortality rate, and re-estrus days were numerically lower in sows with a high feeding allowance. The diet and parity did not individually affect the average duration of farrowing and farrowing intervals. However, the duration of postural changes in sows after farrowing was significantly reduced (p = 0.012). The principal component analysis revealed 81.40% and 80.70% differences upon partial least-squares discriminant analysis. Therefore, increasing feeding allowance during the late gestation period, regardless of parity, could positively influence sows’ reproductive performance and piglets’ growth performance during the lactation phase.

“…The primary controller of body weight is feed intake. Historically, efforts have been made to improve sow condition and piglet performance by regulating feeding strategies [4,7,8]. Numerous studies report that sows with high feed intake and substantial weight mobility during gestation yield larger litter sizes and superior growth performance [9,10].…”

“…Inadequate maternal nutrition can result in insu cient supply of nutrients to meet fetal demand, especially in late gestation and lactation where nutritional requirements increase and voluntary feed intake is often insu cient to satisfy nutrient needs (WU et al, 2006;KIM et al, 2013). During these critical periods, the study of functional nutrients has attracted attention as an attempt to better meet sow nutritional requirements and consequently improve reproductive and growth functions in both sows and their offspring (JI et al, 2017;WU et al, 2017;PEREIRA et al, 2020). In this regard, it is known that large amounts of glutamine (Gln) are mobilized from the maternal body stores to the fetus and mammary gland during gestation and lactation periods, respectively (MANSO FILHO et al, 2008.…”

In order to assess the effects of glutamine (Gln) supplementation on sow and suckling offspring performance, eighty gestating multiparous sows were used in a completely randomized experimental design and a 2 × 2 experimental design in late gestation and lactation, respectively. Females were assigned to a control diet or a Gln-supplemented diet (1% of L-glutamine) from 85 days of gestation until farrowing. In lactation, dietary treatment groups were CON_C: without Gln supplementation; CON_G: Gln only during lactation; GLN_C: Gln only during gestation; GLN_ GLN: Gln during gestation and lactation. At d 105 of gestation, sows fed Gln supplemented diet had greater backfat thickness at point P1 (P = 0.039) and loin depth at point P2 (P = 0.099) than control sows. Litter born from Gln supplemented sows tended to be heavier at birth (P = 0.080) compared to control litters, reducing the probability of piglets weighing less than 1.5 kg. In addition, litters from supplemented sows had a lower standard deviation of BW at birth (P = 0.002). There were no effects of dietary treatments during lactation period. Maternal Gln supplementation during late gestation improved piglet weight and litter uniformity at birth without affecting sow body composition after farrowing.
