Abstract This study was conducted to compare the effects of adding sodium butyrate (SB), medium-chain fatty acids (MCFAs), or n-3 polyunsaturated fatty acids (n-3 PUFAs) to the diet of sows during late gestation and lactation on the reproductive performance of sows and the growth performance and intestinal health of suckling piglets. Twenty-four sows (Landrace × Large-White hybrid; third parity; 200 ± 15 kg) were randomly assigned to receive 1 of 4 diets: basal diet (control group), basal diet + 1 g SB/kg (SB group), basal diet + 7.75 g MCFA/kg (MCFA group), or basal diet + 68.2 g n-3 PUFA/kg (n-3 PUFA group). The experiment began on day 85 of gestation and ended day 22 of lactation. Colostrum samples were collected from each sow. After the experiment, blood and tissue samples were collected from 1 randomly selected piglet. The results showed that the weaning-to-estrus interval of sows in the SB, MCFA, and n-3 PUFA groups was shorter than that of sows in the control group (P < 0.05). The incidence of diarrhea in suckling piglets in the SB, MCFA, and n-3 PUFA groups was lower than that of piglets in the control group (P < 0.05). The fat, protein, IgA, IgG, and IgM concentration in colostrum from sows increased following dietary supplementation with SB, MCFA, or n-3 PUFA (P < 0.05). Comparison with the control group, the mRNA expression of claudin-1, zona occludens 1, and interleukin-10 increased in the jejunum mucosa of suckling piglets in the SB, MCFA, and n-3 PUFA groups, while that of TLR4 decreased (P < 0.05). Compared with the control group, the Chao1 and ACE indexes of microbial flora in the colon contents of piglets in the SB, MCFA, and MCFA groups increased (P < 0.05), while the relative abundance of Firmicutes, Actinobacteria, and Synergistetes decreased at the phylum level (P < 0.05). In conclusion, during late pregnancy and lactation, dietary SB supplementation had a greater effect on intestinal health and caused a greater decrease in preweaning mortality of suckling piglets than did dietary MCFA or n-3 PUFA supplementation; dietary MCFA supplementation shortened the weaning-to-estrus interval of sows to a greater extent than did dietary SB or n-3 PUFA supplementation; and dietary n-3 PUFA supplementation increased the fat and protein content in the colostrum to the greatest extent.

Abstract Forty-seven sows and their progeny were used to determine if feeding gestating and lactating sows a Bacillus licheniformis direct-fed microbial (DFM), an organic acid blend of medium chain and short chain fatty acids (OA), or in combination improves sow lactation feed and water intake, litter growth, and subsequent reproductive performance. On approximately d80 of gestation, sows were fed one of four diets in a 2 x 2 factorial design: 1) gestation control (CON; 0.55% SID Lysine), 2) CON with DFM (1.6x109 CFU/kg of complete feed), 3) CON with 0.4% OA, 4) CON with both DFM and OA. Dietary treatments were also fed throughout lactation (1.00% SID Lysine) starting on approximately d112 of gestation when sows entered farrowing facility. There was a tendency (P = 0.079) for DFM to decrease the amount of sow body weight loss in lactation by approximately 6% compared to sows not consuming the DFM, likely related to DFM sows numerically (P = 0.124) consuming 8.4% more feed during d7-14 of lactation. Sows fed the OA diets had fewer mummies/litter (P = 0.038) compared to diets not containing OA. Sows fed diets with the DFM gave birth to lighter pigs born alive (P = 0.003) compared to non-DFM fed sows, and a tendency for an interaction (P = 0.092) existed where feeding OA+DFM lessened the decrease in born alive BW. There was an interaction tendency (P = 0.133) where sows fed DFM returned to estrus 22 hours sooner than CON, but only 8 hours sooner when sows were fed the OA+DFM diet. In conclusion, feeding a Bacillus licheniformis DFM to sows may decrease pig born alive weight but reduce sow BW loss through 6.4% more lactation feed intake, quickening the return to estrus. Feeding the OA alone or in combination did not improve sow reproductive and litter growth performance in this study, and may require a larger sample size.

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 &lt; 0.05) estrus interval, body weight loss from farrowing to weaning, and increased (P &lt; 0.05) average daily gain from d 7 to 21 in piglet, as well as enhanced (P &lt; 0.05) lactose, fat and protein contents on d 14, and IgA level on d 7 in milk. These sows also had increased (P &lt; 0.05) T-AOC content, reduced (P &lt; 0.05) MDA content in placenta, and improved (P &lt; 0.05) serum T-AOC, GSH-Px and CAT contents at farrowing and weaning. Their piglets behaved higher (P &lt; 0.05) SOD content and lower (P &lt; 0.05) MDA content in serum on d 0, 7, 14, as well as increased (P &lt; 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.
