Distillers dried grains with solubles (DDGS) is a by-product from processing corn to produce bio-ethanol, and it contains almost three times higher protein, fat, and fiber than corn. Intake of higher amount of nutrients originated from corn in lactating sows may contribute to changes in milk composition and thus alter the growth of suckling piglets. Therefore, the objective of this study was to evaluate effect of supplementing DDGS in the diet of lactating sows on variation in the body weight of piglets. A total of 50 sows with parities of 3 to 5 were usedand allottedinto one of four treatments which included 0 (CON), 10% (DDGS10), 20% (DDGS20), or 30% (DDGS30) DDGS in the diet. Diets were fed to sows during the whole lactation period. Individual body weights of piglets were measured within 24 h after farrowing and at weaning. No significant differences were observed inthe coefficient of variation (CV) for body weight of piglets within a litter after farrowing and at weaning among the treatments (p>0.05). There was, however, a tendency of decreases in the CV for body weight of piglets within a litter at weaning compared with that after farrowingin the DDGS10 and DDGS20 treatments. At weaning, the percentage of the number of piglets weighing less than 4.5 kg in DDGS20 (4.86%, 7 out of 144; p<0.05) or DDGS30 (5.04%, 6 out of 119; p=0.059) was lower than that in CON (12.41%; 17 out of 137) although this pattern was not observed in DDGS10. In conclusion, addition of DDGS in lactating sow diets improved piglet performance by reducing the number piglets weighing less than 4.5 kg.
The aim of the present study was to investigate the influences of Curcuma aromatica or inositol monophosphate supplementation on body weight of sows at different stages, feed intake, backfat thickness of sows at different stages, body weight of piglets at different stages, and immunoglobulin G (IgG) concentration in sow blood and milk. Eighteen crossbred (Landrace × Yorkshire) sows (249.9 ± 3.2 kg) and their litters were used in a 28-day feeding trial to observe the effects of Curcuma aromatica or inositol monophosphate as dietary supplements on performance and IgG concentration of blood and milk in lactating sows and piglets. The dietary treatments comprised a control corn-soybean-based basal diet (CON); control diet + Curcuma aromatica at 0.5% (CA), and control diet + inositol monophosphate at 0.10% (IMP). Sow body weight at different stages, average daily feed intake, and sow backfat thickness at different stages were not affected in all three treatment groups. The body weight of piglets at weaning and average daily gain of piglets born to sows from the IMP group showed significant improvement compared to piglets of sows from the CA treatment group. Treatment had no effect on the IgG levels in blood and milk. In conclusion, supplementation of 0.5% CA or 0.10% IMP in sows has no effect on growth performance and IgG in sows and piglets compared with the control diet.

This study aimed to investigate the effects of dietary spray-dried plasma (SDP) on the gut microbiota of lactating sows and their piglets. A total of 12 sows were randomly assigned to one of two dietary treatment groups in a completely randomized design. The treatments were a sow diet based on corn and soybean meal (CON), and a CON diet with an added 1% SDP. The sows were fed the dietary treatments from d 30 before farrowing to weaning (d 28). The fecal samples of three sows from each treatment and two of their randomly selected piglets were collected to verify their fecal microbiota. There were no differences in the alpha diversity and distinct clustering of the microbial communities in the sows and their piglets when SDP was added to the sow diets from late gestation to weaning. The fecal microbiota of the lactating sows and their piglets showed a higher relative abundance of the phylum Bacteroidota and genus Lactobacillus and Ruminococcus and showed a lower relative abundance of the phylum Bacillota and genus Bacteroides, Escherichia/Shigella, and Clostridium in the sows fed the SDP diet than those fed the CON diet. Overall, these results show that the addition of SDP to the sow diet during lactation altered the gut environment with positive microbial composition changes. These results were similar in the nursing piglets, suggesting that the control of the sow diets during lactation may contribute to the intestinal health and growth in piglets after weaning.
The effect of dietary lysine supplementation on the performance of crossbred lactating sows (n = 49, total 92 litters) and suckling piglets during the warm and cool seasons was studied. Sows were randomly allocated to one of two experimental diets, which were fed throughout a 28-day lactation period. Two diets were formulated based on corn-soybean meal with 6% wheat bran, containing 15% crude protein, and with or without 0.25% lysine-HCl supplementation. No interaction was observed between season and dietary lysine supplementation. Dietary lysine supplementation significantly (p<0.05) increased weaning weight (7.11 vs. 6.46 kg) and daily gain (0.20 vs. 0.18 kg) of piglets. During the warm season lactating sows had significantly lower feed intake (3.78 vs. 6.11 kg, p<0.01), higher weight loss (19.81 vs. 9.73 kg, p<0.01) and backfat loss (0.23 vs. 0.06 cm, p<0.01), longer interval from weaning to estrus (9.32 vs. 6.21 days, p<0.05), lower litter weight gain (42.13 vs. 52.90 kg, p<0.01) and lower daily gain (0.17 vs. 0.21 kg, p<0.01) than lactating sows during the cool season. The results indicate that the influences of dietary treatment and season were independent. The 15.0% CP lactation diet with 0.25% lysine-HCl supplementation did not improve the performance of lactating sows and litter piglets, which was impaired by the warm season.
A total of twenty-four multiparous sows (Landrace × Yorkshire) and their litters were used in this 21-day experimental trial. Based on their body weight, sows were randomly allocated into one of three treatments with eight replicates. The dietary betaine supplementation contained three levels: (i) CON (Basal diet + 0% Bet), (ii) Bet 0.05% (CON + 0.05% Betaine), and (iii) Bet 0.15% (CON + 0.15% Betaine). The supplementation of betaine had no effect (p > 0.05) on body weight and feed intake of lactating sow. Moreover, no significant response was observed on backfat thickness, body condition score, and weaning of the estrus interval with the dietary supplementation of betaine. In addition, the litter weaning weight, litter weight gain, average litter daily gain, and survivability rate at birth showed no significant difference with the dietary betaine supplementation of the sow diet. Fecal scores of the lactating sows and suckling piglets were not affected (p > 0.05) with the dietary betaine supplementation compared with the control diet during the experimental periods. The findings of this study showed that betaine supplementation does not boost growth performance, feed intake, body conditions, and fecal score in lactating sows and suckling piglets fed a corn-soybean meal-based diet.
Twenty-five sows and 265 piglets (Landrace ${\times}$ Yorkshire) were used to evaluate the effects of dietary energy level on the pre-weaning and post-weaning performance of piglets and first parity sows. Sows with an average initial B.W. of $217.54{\pm}25.47kg$ were randomly assigned to 2 treatments. The treatments consisted of a T1 diet containing 3,100 kcal, and the T2 diet contained 3400 kcal of metabolizable energy (ME)/kg, respectively. Data were analyzed using Duncan statements to test the effect of the dietary energy levels on growth performance in lactating sows and piglets. In this study, Dietary T2 sows had a greater number of weaned piglets per litter (p < 0.05). Dietary T2 had a higher (p < 0.05) body weight than that of T1 in the weanlings, meanwhile it had a higher total average daily gain (p < 0.05) than that of T1. Dietary T1 had a higher average feed intake than that of T2 in gestation and lactation. There were no significant differences on the litter size or litter birth weight. No differences (p > 0.05) were noted in the survival of the piglets as well as in the backfat thickness and body weight loss in sows. In conclusion, these results show that high-energy diets had no effect on the body weight and backfat thickness of sows during gestation and lactation but influenced the body weight and average daily gain of weanling pigs during the lactation period.

The objective of this study is to investigate the effect of dietary glucose oxidase (GOx) supplementation on the reproductive performance, litter performance, total tract digestibility, and blood profile of lactating sows fed corn- wheat-based diet. A total of twenty multiparous sows (Landrace × Yorkshire) were allocated into one of four treatments with five replicates per treatment. The dietary treatments were as follows: CON (Basal diet), GO1 (basal diet + 200 U GOx/kg), GO2 (basal diet + 300 U GOx/kg), GO3 (basal diet + 400 U Gox/kg). Dietary GOx supplementation did not affect lactating sow's reproduction performance as well as body weight, backfat thickness, and body condition score during pre and post farrowing, and at weaning (p > 0.05). However, after farrowing to weaning period lactating sow's fed GOx supplement has linearly (p = 0.0196) decreased the bodyweight loss. While, there were no effects (p > 0.05) observed on sows backfat thickness loss, average daily feed intake, and estrus interval among treatment groups. Dietary supplementation of GOx has linearly improved the body weight gain (p = 0.049) and average daily gain (p = 0.040) of suckling piglets. The total tract digestibility of dry matter and nitrogen was linearly increased with the graded level of GOx supplement. Also, a linear effect was observed on the glucose and superoxide dismutase of blood profile with the dietary inclusion of GOx. In summary, our finding indicates that the dietary inclusion of GOx supplement with corn- wheat-based diet had a beneficial effect on the nutrient digestibility and blood profile of lactating sows and improved the growth performance of suckling piglets.

In the present study, offsprings of 14 sows were used to evaluate the effect of fermented milk substituted for creep feed to analyze its effect on growth performance, diarrhea score and blood profiles. The piglets of sows were randomly allocated into 1 of 2 treatments (1 treatment separated piglets of 7 sows). The dietary treatments includes: CF (creep feed) and FM (fermented milk). The CP and FM diets were given from 3 d after piglets were born to the day of weaning (21 d after piglets were born). No significant difference (P>0.05) were observed in number of born piglets, weaning pigs, survival rate, body weight of piglets at d 0, 7, 14, and 21, ADG and ADFI. At d 21, piglets fed with CP had a higher (P<0.05) IgG compared with piglets fed with FM. No significant difference (P>0.05) was observed in WBC among the treatments at d 21. At d 6, piglets fed with CP had a lower (P<0.05) number of diarrhea piglets compared to piglets fed with FM. In conclusion, FM substituted for CP had no adverse effect on growth performance in lactating piglets.

Objective: This study was conducted to evaluate the effects of β-glucan with vitamin E supplementation on the physiological response, litter performance, blood profiles, immune response, and milk composition of lactating sows. Methods: A total of 50 multiparous F1 sows (Yorkshire×Landrace) with an average body weight (BW) of 233.6±4.30 kg and an average parity of 4.00±0.307 and their litters were used in this experiment. All sows were allotted to one of five treatments, taking into consideration BW, backfat thickness, and parity in a completely randomized design with 10 replicates. The experimental diets included a corn-soybean meal-based basal diet with or without 0.1% or 0.2% β-glucan and 110 IU vitamin E/kg diet. Results: All treatments added with β-glucan or vitamin E were statistically higher in the average daily feed intake (ADFI) of lactating sows compared to those of the control (Diet, p<0.01). Additionally, the ADFI of lactating sows was significantly higher in the groups supplemented with 0.1% β-glucan compared to 0.2% β-glucan (BG, p<0.01). There was an increasing trend in piglet weight at weaning (BG, p = 0.07), litter weight at the 21st day of lactation (BG, p = 0.07) and litter weight gain (BG, p = 0.08) in groups supplemented with 0.1% β-glucan. The addition of 110 IU vitamin E/kg diet increased vitamin E concentration significantly in lactating sows (VE, p<0.01) and exhibited a trend for higher concentrations of vitamin E (VE, p = 0.09) in piglets. Adding 0.1% β-glucan compared to 0.2% β-glucan induced a decrease in the concentration of tumor necrosis factor-α in lactating sows (BG, p = 0.06) and in piglets (BG, p = 0.09) on the 21st day of lactation. There were no significant differences in the milk composition of sows. Conclusion: Adding 0.1% β-glucan and 110 IU vitamin E/kg to a lactating sow's diet was beneficial to the growth performance of piglets by leading to an increase in the feed intake of sows and efficiently supplying vitamin E to both the sows and piglets.

Offspring of 14 sows were used to evaluate the effect of yogurt substituted for creep feed on growth performance, diarrhea score and blood profiles. The piglets of sows were randomly allocated into 1 of 2 treatments (1 treatment separated piglets of 7 sows). The dietary treatments were as followed: CF, creep feed; YG, yogurt. The creep feed and yogurt diets were given from 3 d after piglets were born to the day of weaning (21 d after piglets were born). The body weight and feed consumption were weighed and recorded at d 0, 7, 14, and 21 after piglets were born for calculating average daily gain (ADG) and average daily feed intake (ADFI). At the weaning day, two piglets were randomly chosen from each pen and bled via jugular venipuncture to obtain blood samples for WBC and IgG measurement. All data were subjected to the GLM procedures of SAS (2002) as a randomized complete block design, with pen as the experimental unit. Differences among dietary treatments were separated by Duncan's multiple range test, and P < 0.05 was considered statistically significant. No significant difference (P > 0.05) were observed in number of born piglets, weaning pigs, survival rate, body weight of piglets at d 0, 7, 14, and 21, ADG and ADFI. At d 21, piglets fed with creep feed had a higher (P < 0.05) IgG compared with piglets fed with yogurt. No significant difference (P > 0.05) was observed in WBC among treatments at d 21. In conclusion, yogurt substituted for creep feed had no adverse effect on growth performance in lactating piglets.
