“…Ability to produce colostrum and milk are some of the most important performance traits for lactating sows to ensure the survival of their piglets 1 , 2 . The main composition of sow colostrum and milk includes fat, proteins, lactose, vitamins, minerals as well as a series of immunoglobulins, which provide a good source of nutrients and passive immunity that support the growth and survival of piglets 3 , 4 .…”

The objective of this study was to investigate the impact of lactation stage and parity number on fatty acid and non-volatile polar metabolite profiles in sow colostrum and milk using a metabolomics approach. A total number of 63 colostrum, transient and mature milk were collected from primiparous and multiparous Landrace × Yorkshire crossbred sows. Macrochemical, fatty acid and non-volatile polar metabolite compositions of samples were analyzed using infrared spectrometry, gas chromatography coupled with mass-spectrometry and proton nuclear magnetic resonance spectroscopy, respectively. Univariate and multivariate statistical analysis demonstrated significant impacts of lactation stage and parity number on colostrum and milk compositions. Chemometric analysis revealed significant influences of sow parity on the distinction in fatty acid profiles of mature milk while the distinction in non-volatile polar metabolite profiles was more evident in colostrum. Alterations in the concentration of linoleic (C18:2n6), lignoceric (C24:0), behenic (C22:0), caprylic (C8:0) and myristoleic (C14:1) acid together with those of creatine, creatinine phosphate, glutamate and glycolate were statistically suggested to be mainly affected by sow parity number. Variations in the concentration of these compounds reflected the physiological function of sow mammary gland influenced. This information could be applied for feed and feeding strategies in lactating sows and improving lactating performances.

“…The current study showed that there were no significant differences in BW and BW changes by Se sources or levels, which matched previous studies. Backfat (BF) thickness is a significant parameter to evaluate fat storage in sows, and the change in BF thickness had a high c orrelation with sow BW loss and feed intake during the lactation period [19]. Mahan et al [20] reported that short-term feeding of either Se source at 0.15 or 0.30 ppm Se did not affect BF changes and feed consumption in lactating sows.…”

Objective: This study was conducted to evaluate the short-term effects of dietary selenium supplementation on lactating sows on the physiological response, litter performance, milk composition, and tissue selenium retention in piglets when selenium was provided by different sources and at different levels in a lactation diet.Methods: A total of 48 multiparous sows (Yorkshire × Landrace) with average body weight (BW), backfat thickness (BF), and parity were assigned to one of the four treatments with 12 sows per treatment using a 2 × 2 factorial arrangement in a completely randomized design (CRD). Inorganic or organic Se sources were added to the diet at 0.30 ppm and 0.50 ppm Se.Treatments were as follows: 1) IS30: basal diet + inorganic Se 0.30 ppm, 2) IS50: basal diet + inorganic Se 0.50 ppm, 3) OS30: basal diet + organic Se 0.30 ppm, and 4) OS50: basal diet + organic Se 0.50 ppm. Results:At Day 21 of lactation, a high tendency of litter weight (p=0.08) and litter weight gain (p=0.09) were observed when sows were fed an organic Se source. The milk Se concentration in the organic Se treatment was higher than that in the inorganic Se treatment at Day 21 of lactation (p<0.05). The serum Se concentrations of sows and piglets at Day 21 of lactation were significantly higher when lactating sows were fed organic Se instead of inorganic Se (p<0.01).During the suckling period, the kidney and muscle Se concentrations of piglets at Day 21 of lactation were significantly higher when the sow dietary Se source was organic (p<0.05). Liver Se concentrations were affected by Se source and level (p<0.05). This also resulted in an interaction response at 21 days of lactation (p<0.05). Conclusion:The supplementation of dietary organic Se in a lactating diet could improve sow feed consumption, piglet performance, milk Se levelcomposition, and the Se status of sows and A c c e p t e d A r t i c l e 3 piglets.

“…In relation to a 200 kg sow and a 300 kg sow, this means that the 300 kg sow has 50% more body mass, but only 35 % more heat production. This statement probably applies even more strongly today because, due to increased fertility performance, feed intake has increased in recent decades, especially during lactation (57). For this reason, large animals must consume less feed per kg of body mass than small animals; therefore, perhaps less metabolic heat is produced from feed intake.…”

Precision livestock farming can combine sensors and complex data to provide a simple score of meaningful productivity, pig welfare, and farm sustainability, which are the main drivers of modern pig production. Examples include using infrared thermography to monitor the temperature of sows to detect the early stages of the disease. To take account of these drivers, we assigned 697 hybrid (BHZP db. Viktoria) sows to four parity groups. In addition, by pooling clinical findings from every sow and their piglets, sows were classified into three groups for the annotation: healthy, clinically suspicious, and diseased. Besides, the udder was thermographed, and performance data were documented. Results showed that the piglets of diseased sows with eighth or higher parity had the lowest daily weight gain [healthy; 192 g ± 31.2, clinically suspicious; 191 g ± 31.3, diseased; 148 g ± 50.3 (p < 0.05)] and the highest number of stillborn piglets (healthy; 2.2 ± 2.39, clinically suspicious; 2.0 ± 1.62, diseased; 3.91 ± 4.93). Moreover, all diseased sows showed higher maximal skin temperatures by infrared thermography of the udder (p < 0.05). Thus, thermography coupled with Artificial Intelligence (AI) systems can help identify and orient the diagnosis of symptomatic animals to prompt adequate reaction at the earliest time.
