Abstract This study aims to evaluate the effects of dietary Forsythia suspensa extract (FSE) supplementation in sows during late gestation on reproductive performance, colostrum composition, antioxidant status and immune function [NSFC 31772612]. Forty Yorkshire × Landrace gestating sows (average parity of 3.28 ± 0.61; average body weight of 240.16 ± 6.81 kg) were assigned to 2 treatments with 20 sows per treatment based on body weight, back fat thickness and parity. From d 85 of gestation to farrowing, sows were supplemented with a control diet (corn-soybean meal basal diet, CON), and a FSE diet (basal diet + 100 mg / kg FSE). The results showed that sows fed FSE had increased (P < 0.05) litter weight, fat and protein contents in colostrum compared with CON. Dietary FSE supplementation in sows could increase (P < 0.05) total antioxidant capacity and superoxide dismutase contents, and decrease (P < 0.05) the content of malondialdehyde in colostrum, and increase (P < 0.05) the contents of catalase and glutathione peroxidase in serum of their offspring compared with CON. Additionally, sows fed FSE could also increase (P < 0.05) the content of immunoglobulin A in serum of their offspring compared with CON. Sows fed FSE had decreased (P < 0.05) content of interleukin-6 (IL-6) and increased (P < 0.05) content of IL-10 in serum and colostrum of sows, and decreased (P < 0.05) contents IL-6 and IL-8 in serum of their offspring compared with CON. Sows fed FSE showed increased (P < 0.05) content of glucose in colostrum and decreased (P < 0.05) content of serum urea of their offspring compared with CON. In conclusion, dietary FSE supplementation in sows during late gestation could improve litter weight, colostrum fat and protein contents, antioxidant status, immunoglobulin, inflammatory cytokines of sows and piglets.

Abstract Lactating sows face various stresses, leading to poor reproductive performance and high mortality in piglets. Previous studies have demonstrated Forsythia suspensa extract (FSE) has antioxidant and antibacterial functions in broilers and piglets. However, rare researches focus on the effect of FSE in lactating sows. Therefore, this experiment was conducted to investigate dietary FSE supplementation on performance, antioxidant status and immunity in sows and piglets. 24 healthy Yorkshire × Landrace sows (average body weight of 234 ± 6.81 kg; average parity of 3.38 ± 0.61) were allotted into 2 dietary treatments with 12 sows per treatment based on parity, back fat thickness and body weight. Sows were fed a corn-soybean meal basal diet (CON), or a FSE diet (basal diet+100 mg/kg FSE) from d 107 of gestation until d 21 of lactation. Compared with CON, sows fed FSE showed decreased (P < 0.05) estrus interval, body weight loss from farrowing to weaning, and increased (P < 0.05) average daily gain from d 7 to 21 in piglet, as well as enhanced (P < 0.05) lactose, fat and protein contents on d 14, and IgA level on d 7 in milk. These sows also had increased (P < 0.05) T-AOC content, reduced (P < 0.05) MDA content in placenta, and improved (P < 0.05) serum T-AOC, GSH-Px and CAT contents at farrowing and weaning. Their piglets behaved higher (P < 0.05) SOD content and lower (P < 0.05) MDA content in serum on d 0, 7, 14, as well as increased (P < 0.05) serum T-AOC and GSH-Px contents on d 21. These piglets also had higher villus height and villus height to crypt depth ratio in jejunum on d 21 compared with CON. In conclusion, dietary FSE supplementation improved performance, antioxidant status and immune function in lactating sows and suckling piglets.

Arginine Supplementation

This study was conducted to evaluate the effects of L-arginine supplementation levels during late gestation on reproductive performance and piglet uniformity in high prolific sows. A total of 60 F1 multiparous sows (Yorkshire × Landrace), with an average body weight of 238.2 kg, were allotted to one of three treatment groups in a completely randomized design. The dietary treatments were divided by the supplementation level of arginine during the late-gestation period, from day 70 to farrowing, as follows—(1) CON: corn-soybean meal-based basal diet (Arg 0.72%), (2) Arg10: basal diet + L-Arg 0.28% (Arg 1.0%), and (3) Arg15: basal diet + L-Arg 0.79% (Arg 1.5%). The same lactation diet was provided ad libitum to sows during the lactation period. There were no significant differences in body weight and backfat thickness in sows during late-gestation and lactation. Dietary arginine levels had no significant influences on the number of total born, stillbirth, and born alive. However, increasing inclusion level of L-arginine supplementation tended to increase (p < 0.10) alive litter weight linearly, and also linearly increased (p < 0.05) the piglet weight gain and litter weight gain during the lactation period. In piglet uniformity, the standard deviation of piglet birth weight (p < 0.05) and the coefficient of variation for piglet birth weight (p < 0.10) increased linearly, as dietary arginine levels increased in the late gestation period. Increasing L-arginine supplementation to late gestating sows linearly increased (p < 0.05) the blood concentrations of arginine and ornithine at day 90 and day 110 of gestation. On the other hand, dietary arginine levels in late gestation did not affect the blood parameters related to the nitrogen utilization. Increasing dietary arginine levels for the late gestating sows did not affect the milk composition for colostrum and milk at day 21 of lactation. In conclusion, the inclusion level of arginine in the diet for late gestating sows, by up to 1.5%, could improve the alive litter weight at birth and litter weight gain during lactation, whereas the piglet uniformity at birth was decreased due to the increase of survival for fetuses with light birth weight.

Abstract Sow feed intake during lactation is crucial to the maintenance of sow body condition, milk production, and litter performance. Loss of body weight or condition during this time could compromise future reproductive performance. Two groups (n = 52 total) of breeding age gilts and sows were used to evaluate whether a sensory additive would improve intake during the lactation period. Gilts/Sows were weighed, and back fat depth was measured, at 110 d of gestation prior to entering the lactation room, and again at weaning. The sows were sorted by parity and then allotted by BW at d 110 to Control or 0.075% sensory additive (Luctamax® SowVive, Lucta S.A., Barcelona, Spain). Experimental lactation diets were offered upon entry to the lactation room and fed through weaning. During this time feed was weighed back every three days. Gilts/sows were fed 2.72 kg/head/day until farrowing, and sows were placed on full feed 24 hours post-farrowing and allowed to eat ad libitum. Data was analyzed using the PROC MIXED of SAS as an RCBD with treatment as the fixed effect and group as a random effect. During lactation sows on the sensory additive diet showed an increase in intake during days 10 to 21 when compared to sows on the control diet (Table 1). Although it was not significantly different, sows fed sensory additive had numerically heavier weaning BW (239.4 vs 236.2 kg, P = 0.42) and increased litter weight gain (51.96 vs 48.69 kg, P = 0.24) compared to control fed sows. However, backfat thickness change during lactation did not differ between control and sensory additive fed sows (-4.74 vs -5.81 mm, P = 0.65). In conclusion, in the current study lactation diets supplemented with a sensory additive stimulated sow appetite during the lactation period.

Abstract Most sows are fed a constant energy and amino acid supply throughout gestation, in line with the recommendations of most authorities and swine genetic companies. These recommendations for sow feeding have seen little change in decades, despite the many ways that sows have changed dramatically in reproductive performance. Beginning in about the year 2000, sow litter size has steadily increased as a result of genetic selection. With this increase in litter number has been a steady decline in birth weight, and the resulting negative effects of lower birthweight on subsequent piglet performance. Many experiments using so-called ‘bump’ feeding, or increased energy intake in late gestation, have been conducted in attempts to arrest this decline in birthweight and piglet performance. Generally, these experiments have shown little to no improvement in birthweight and often have negative effects on sow feed intake during gestation. These experiments have ignored the fact that the energy:amino acid ratios (lysine, threonine, isoleucine, tryptophan) in late gestation are different than during early and mid-gestation. In recent research in Australia we hypothesised that rapidly increasing essential amino acid levels in late gestation would increase birth weight and potentially improve subsequent reproductive performance. Three hundred and thirty-four multiparous PIC sows (average parity 3.6, average LW 261 kg) were housed in a dynamic gestation pen after mating and randomly assigned to one of two diet regimes. Two 13.5 MJ/kg DE gestation diets were formulated and created by blending in an ESF. The Control diet contained 0.48 g SID lysine per MJ DE and SID threonine, methionine+ cysteine, isoleucine and tryptophan at 68%, 65%, 58% and18% of SID lysine and offered at 2.2kg/day from d 28 to d 110. Sow were then moved to the farrowing house and placed on a lactation diet at 3.5kg/d. The Treatment diet contained 0.55 g SID lysine/MJ DE and SID threonine, methionine+cysteine, isoleucine and tryptophan at 78%, 65%, 60% and 20% of SID lysine and offered at 2.1kg/d from d 28 to d 85 and then increased to 2.4 kg/d to d 110 d. Increasing essential amino acid levels in late gestation increased gestational weight gain (5.6 kg, P=0.004), increased total litter birth weight (1.25 kg, P=0.003), and increased the birthweight of liveborn pigs from 1.286 to 1.329 kg, (P=0.04). There was no significant effect on the total number born or born alive. Piglet performance is not available because this commercial farm practices cross-fostering. Effects of continuation of this feeding regime in the same sows during subsequent parities is currently being evaluated.

Abstract In this study, the effects of maternal energy sources during late gestation and lactation on the performance, glucolipid metabolism, and oxidative status of sows and their offspring were investigated using a total of 75 (2 to 6 of parity) Landrace × Large White sows at day 85 of gestation under 3 different dietary treatments: SO diet (basal diet plus 3.0% and 5.0% soybean oil during late gestation and lactation, respectively), FO diet (basal diet plus 3.0%/5.0% fish oil during late gestation and lactation, respectively), and CS diet (basal diet plus 32%/42% corn starch during late gestation and lactation, respectively). All the 3 groups showed no obvious differences (P > 0.05) in the number of total piglets born, born alive, after cross-fostering, and at weaning, whereas the CS group exhibited a shorter farrowing duration (P < 0.05) and lower stillbirth rate (P < 0.05) when compared with the SO group. In addition, litter weight at birth was significantly higher in the CS group than in the SO or FO group (P < 0.05). Despite no notable differences in the ADG of suckling piglets among dietary treatments (P > 0.05), the CS group had greater feed intake than the SO group during the lactation period (P < 0.05). In neonatal piglets with normal birth weight (NBW, 1.3 to 1.5 kg), the CS group was lower than the SO group in the content of liver glycogen (P < 0.05) and the mRNA abundances of fatty acid synthase, acetyl-CoA carboxylase, fatty acid-binding protein 1, and acyl-CoA oxidase (P < 0.05). Interestingly, compared with the SO group, the FO group had a lower preweaning mortality rate (P < 0.05), but greater liver glycogen pools (P < 0.05) in neonatal piglets with low birth weight (LBW, <1.1 kg). Compared with the CS group, the FO group showed an increase in the plasma malondialdehyde levels (P < 0.05) of sows, as well as an increase of 8-hydroxy-deoxyguanosine (P < 0.05) and a decrease of ferric reducing ability of plasma (P < 0.05) in NBW piglets. Overall, the diet rich in starch decreased the stillbirth rate and increased the litter weight of neonatal piglets, the dietary supplementation with fish oil decreased preweaning mortality rate, and the diet with a low n6:n3 ratio increased the oxidative status of sows and their offspring.

Weight Variation

The high within-litter birth weight variation has become a big issue in multiparous animals. The present study was conducted to investigate the effects of leucine supplementation in premating diet on the reproductive performance, maternal antioxidative capability, and immune function in primiparous rats. Six-week-old female SD rats were assigned to basal diet or 0.6% leucine supplemented diet for two weeks. After mating during the eighth week of age, the rats were fed with regular gestation diet. Maternal blood samples were collected on the day before mating (day −1) and day 7 and day 20 of pregnancy, while ovaries and uteruses were obtained on day −1 and on day 7, respectively. The results indicate that, compared with control group, within-litter birth weight variation was significantly decreased, while birth weights were significantly increased in the leucine group (P<0.01). Also, leucine improved the embryo distribution uniformity and the number of implantation sites in uterine. The ovarian gene expressions of LHR, CYP19A1, and VEGFA were upregulated, while Mucin-1 was decreased significantly (P<0.05). Leucine also increased the maternal antioxidant capacity and immune function. Conclusively, leucine supplementation in premating diet could improve the reproductive performance, which could be attributed to the improved oxidative and immune status.

The effect ofHibiscus sabdariffaL. (Hs) calyx extract on fat absorption-excretion and body weight in rats, was investigated. Rats were fed with either a basal diet (SDC = Control diet) or the same diet supplemented with Hs extracts at 5%, 10% and 15% ( , and ). Only did not show significant increases in weight, food consumption and efficiency compared to . The opposite occurred in group which showed a significant decrease for these three parameters. The responses were similar to , with the exception of food consumption. In both and groups, no body weight loss was observed; however, only in the latter group was there a significantly greater amount of fatty acids found in feces. A collateral effect emerging from the study is that components of Hs extract at the intermediate and greater concentrations used in this experiment could be considered possible antiobesity agents.

Abstract The impacts of probiotics supplementation on reproduction performance and noxious gas emission in sows was evaluated in an experiment with a total of thirty sows (second-parity), from 4 weeks prior to farrowing, to day 21 of lactation. The gestation and lactation diets of sows were supplemented with probiotics containing Bacillus subtilis (1.2 × 107 cfu/g) and Lactobacillus acidophilus (1.15 × 106 cfu/g). Treatment included: basal diet (CON), basal diet + 0.1% probiotics (PB0.1), and basal diet + 0.2% probiotics (PB0.2). The supplementation of dietary probiotics significantly improved average daily feed intake during the lactation period (quadratic, P = 0.0429), sow backfat thickness during the weaning period (linear, P = 0.0385), and initial body weight of piglets (linear, P = 0.0054) as compared with CON, respectively. Furthermore, the supplementation of dietary probiotics reduced noxious gas emission as compared with CON (linear, P<0.05 for day 5 and day 10), respectively. In conclusion, dietary probiotics containing B. subtilis and L. acidophilus improved the growth performance of sows, resulted in increased weaning body weight of piglets, and induced an effective and significant reduction in fecal noxious gas emission in lactating sows, as compared with CON.
