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 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.

Abstract The objective of this study was to determine the effects of increased AA and energy intake during late gestation on reproductive performance, milk composition, and metabolic and redox status of sows. A total of 118 Yorkshire sows (third through sixth parity) were randomly assigned to dietary treatments from day 90 of gestation until farrowing. Dietary treatments consisted of combinations of 2 standardized ileal digestible (SID) AA levels [14.7 or 20.6 g/d SID Lys, SID Lys and other AA met or exceeded the NRC (2012) recommendations] and 2 energy levels (28.24 or 33.78 MJ/d intake of NE) in a 2 × 2 factorial design. After parturition, all sows were fed a standard lactation diet. Blood samples were collected and analyzed for parameters on metabolism, redox status, and amino acid profile. The data were analyzed using the generalized linear mixed models to reveal the impact of dietary levels of energy, AA, and their interaction. Sows with increased intake of AA had greater BW gain (P < 0.01) during late gestation. Furthermore, the BW loss during lactation was increased in sows with increasing intake of energy (P < 0.05) or AA (P < 0.05). Sows fed high energy had higher total litter birth weights (20.2 kg vs. 18.4 kg, P < 0.05) and shorter duration of farrowing (261 min vs. 215 min, P < 0.05), compared with those fed low energy, which likely was due to higher (P < 0.05) plasma glucose and lower (P < 0.05) plasma lactate prior to parturition. High AA intake in late gestation increased the ADG of piglets during the following lactation (P < 0.05), and increased the concentrations of plasma urea, and the following AA: Lys, Met, Thr, Val, Ile, Leu, Phe, Asp, Ser, and Arg at farrowing (P < 0.05). In conclusion, the increased intake of energy increased total litter weight of newborns and shortened the farrowing duration, which likely was due to improved energy status at farrowing. Furthermore, sows with increased intake of AA led to higher growth rate of piglets during the following lactation, accompanying with the increasing levels of plasma urea and amino acids. Therefore, the higher energy intake in late gestation appeared to improve litter weight and farrowing duration, while higher AA intake may have positive effect on piglets performance in lactation.

Abstract This experiment was conducted to research the effects of different dietary levels of lactic acid bacterial (LAB) in sows’ diet during lactation on piglet growth performance, serum biochemical indices and amino acid of sows. 40 late gestation (110 d) sows with parity 3 or 4 were randomly divided into 5 groups with 8 sows per group. 0, 50, 100, 200, 300 mL Lactobacillus liquid (live LAB concentration was ≥1 *109 CFU/mL) was fed per sow per day for experimental groups L0, L50, L100, L200, L300, respectively. The durations of the test were 35 days. Results showed that, litter weight at weaning from group C grew slower than piglets from groups of L100, L200, L300 (P &lt; 0. 05). Average piglet weight gain from day 1 to 21 of lactation was higher in L200 compared with groups C and L50 (P &lt; 0. 05). Number of weaned pigs increased linearly with dietary LAB level (P = 0.037, r2 = 0.146, y=8.335 + 0.005x). Total litter weight gain from day 0 to 21 increased linearly with the dietary LAB level (P = 0.005, r2 = 0.288, y=15.797 + 0.040x). Serum GLU concentration was smaller in group L50 compared with other groups (P &lt; 0.05). Serum TC concentration was higher in group L100 and lower in groups L200 and L300 (P &lt; 0.05).The values of those amino acids such as leucine, lysine, valine, arginine, cysteine, ornithine were all higher in the sows fed 50 mL LAB than other groups (P &lt; 0.05).In summary, our results have revealed the ability of addition of LAB in sows’ diet during lactation significantly modify piglet growth. Addition of 200 mL LAB liquid seems to be more effective in elevating weight of weaning piglets.

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 &lt; 0.05) litter weight, fat and protein contents in colostrum compared with CON. Dietary FSE supplementation in sows could increase (P &lt; 0.05) total antioxidant capacity and superoxide dismutase contents, and decrease (P &lt; 0.05) the content of malondialdehyde in colostrum, and increase (P &lt; 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 &lt; 0.05) the content of immunoglobulin A in serum of their offspring compared with CON. Sows fed FSE had decreased (P &lt; 0.05) content of interleukin-6 (IL-6) and increased (P &lt; 0.05) content of IL-10 in serum and colostrum of sows, and decreased (P &lt; 0.05) contents IL-6 and IL-8 in serum of their offspring compared with CON. Sows fed FSE showed increased (P &lt; 0.05) content of glucose in colostrum and decreased (P &lt; 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 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.

Arginine Supplementation

Arginine (a non-essential amino acid) and its conversion to nitric oxide (NO) can promote formation of new blood vessels and cause vasodilation. This may reduce resistance and increase blood flow to the uterus and placenta, and the delivery of nutrients for fetal growth and survival. In pregnant rats, dietary arginine deficiency causes IUGR and increases fetal death and perinatal mortality, whereas dietary arginine supplementation reverses this. Human IUGR is associated with impaired NO synthesis, and eNOS activity in umbilical vein endothelial cells, but maternal arginine supplements have produced inconclusive results. We hypothesised that maternal arginine supplementation (MAS) in the pig (a species with naturally occurring IUGR), during late gestation, when placental angiogenesis and vascularity increase, would increase birth and placental weights. Large White (LW) and Landrace (LR) gilts (n = 285) and sows (n = 326), were fed either a control or arginine supplemented (+25 g/d arginine, Nutreco Progenos premix) diet (2.5 kg/d) in late gestation (d75-term at ~114 days). Number born, born alive, still born and mummified, birth weight and d10 weight of progeny were measured. Data were analysed using Univariate ANOVA. MAS in late gestation in gilts and sows reduced the number of still born (Con: 1.17 ± 0.13 piglets/litter; Arg: 0.84 ± 0.09 piglets/litter; P = 0.046). In LW gilts, MAS increased birth weight (Con: 1.21 ± 0.05kg; Arg: 1.34 ± 0.05kg; P < 0.05), and litter birth weight (Con: 13.38 ± 0.72 kg; Arg: 15.27 ± 0.73 kg; P < 0.05). MAS also increased birth weight in LW (Con: 1.17 ± 0.06 kg; Arg: 1.30 ± 0.06 kg; P < 0.05) and LR (Con: 1.47 ± 0.05 kg; Arg: 1.60 ± 0.05 kg; P < 0.05) sows, and reduced still borns in LW sows (Con: 1.12 ± 0.14 piglets/litter; Arg: 0.77 ± 0.09 piglets/litter; P < 0.05). MAS in late gestation improves pregnancy outcomes in terms of piglet survival and birth weight, in LW and LR gilts and sows. MAS during critical periods of placental development may enhance placental-fetal blood flow and nutrient transfer, thereby improving fetal growth and survival.

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.

AbstractScottish Blackface ewes (no. = 308) were scanned four times per year using X-ray computed tomography (CT scanning) (pre-mating, pre-lambing, mid lactation and weaning), from 18 months to 5 years of age, giving a maximum of 16 scanning events per ewe. Total weights of carcass fat, internal fat and carcass muscle were estimated from the CT images at each scanning event. Lambs produced by these ewes were weighed at birth, mid lactation and weaning to calculate litter growth traits: litter birth weight; litter weight gain from birth until mid lactation; and litter weight gain from birth until weaning. Genetic (rg) and phenotypic (rp) correlations were estimated between ewe CT tissue traits and litter growth traits. Correlations between ewe CT tissue traits and litter size (LS) were also estimated. Ewe CT tissue traits were either unadjusted or adjusted for total soft tissue weight (sum of weights of carcass fat, internal fat and carcass muscle) to investigate relationships with either absolute tissue weights of carcass fat (CFWT), internal fat (IFWT), and carcass muscle (CMWT), or relative proportions of carcass fat (CFP), internal fat (IFP), and carcass muscle (CMP). Litter growth traits were either unadjusted or adjusted for litter size, to investigate relationships with total lamb burden (total litter birth weight (TBW), total litter weight gain from birth until mid lactation (TWGM), total litter weight gain from birth until weaning (TWGW)) or average lamb performance (average lamb birth weight (ABW), average lamb weight gain from birth until mid lactation (AWGM), average lamb weight gain from birth until weaning (AWGW)).Moderate to large positive genetic correlations were estimated between absolute weights of all three ewe tissues (CFWT, IFWT, CMWT), or muscle proportion (CMP), and litter size (LS). Significant positive genetic correlations were also estimated between weight (CMWT) or proportion (CMP) of muscle carried by the ewe pre-mating and total birth weight (TBW) and weight gains (TWGM, TWGW) of her litter, largely due to the associated increase in litter size. Muscle proportion (CMP) was not significantly correlated to average lamb weights or weight gains (ABW, AWGM, AWGW). Pre-lambing carcass fat weight (CFWT) and proportion (CFP) in the ewe showed positive genetic correlations with average lamb weights and weight gains (ABW, AWGM, AWGW), whereas, after lambing, CFP was negatively correlated with these lamb traits. Internal fat weight (IFWT) pre-mating showed positive genetic correlations with all litter growth traits (TBW, TWGM, TWGW, ABW, AWGM, AWGW). Average lamb growth traits were negatively correlated with pre-lambing internal fat proportion (IFP), but positively correlated to IFP at mid lactation and weaning.Correlations were also estimated between each pair of CT traits. Total internal fat weight and total carcass fat weight were very highly correlated (rp= 0·75,rg= 0·96). Correlations with total carcass muscle weight were smaller and positive for both carcass fat weight (rp= 0·48,rg= 0·12) and internal fat weight (rp= 0·42,rg= 0·20).The results suggest that selection for increased carcass muscle weight or proportion in a Scottish Blackface hill flock would have a positive effect on total weights of litters reared, but that selection against carcass fat weight or proportion in a breeding programme for Blackface sheep may have an impact on the maternal ability of the ewe. However, maintaining fat in internal depots may reduce the depletion of carcass fat during pregnancy, allowing this depot to provide energy for lactation, and may have a positive impact on lamb growth.

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.
