This study investigated the effects of different amounts of wheat aleurone(WA)(0,15%,30%)inclusion in gestation diets on the reproductive performance,postprandial satiety,stress status and stereotypic be-haviors of sows.A total of 84 Landrace×Yorkshire sows(parity 4.87±1.32)at breeding were randomly allotted to one of the three isoenergetic and isonitrogenous dietary treatments based on parity and body *** results showed that,compared with the control(0),sows fed the WA diet had a higher serum concentration of peptide YY(PYY)(P<0.05)and glucagon like peptide-1(GLP-1)(P<0.05)and a lower concentration of saliva cortisol(P<0.01).Importantly,compared with the control group,only the 15%WA group had a higher concentration of the total antioxidant capacity(T-AOC)(P<0.05),lower pro-portions of sitting(P=0.05)and stillbirth rates(P<0.01).Accordingly,the production cost per piglet born alive($6.9 vs.$7.6)or per piglet born healthy($7.4 vs.$7.9)declined in the 15%WA group versus the control ***,15%WA inclusion in gestation diets contributed to enhancing postprandial satiety,alleviating stress status and decreasing stillbirth rate of *** study provides a reference for the application of WA as a partial substitute for conventional feed ingredients to improve sows'repro-ductive performance.

This study aimed to investigate the effects of different levels of black soldier fly(BSF)replacing soybean meal(SBM)in diets on the performance and health condition of piglets.A total of 180 weaned piglets were allocated into 5 treatments:BSF0(corn-soybean meal basal diet),BSF25(BSF replacing 25%SBM),BSF50(BSF replacing 50%SBM),BSF75(BSF replacing 75%SBM)and BSF100(BSF replacing 100%SBM).During the whole period,in comparison with BSF0,average daily gain(ADG)and average daily feed intake increased in the BSF25 and BSF50 groups,whereas ADG decreased in the BSF75 and BSF100groups(P<0.05).The result of quadratic fitting curve showed that piglets exhibited the highest ADG when BSF replaced around 20%*** with BSF0,organic matter and dry matter digestibility improved in the BSF25 group,whereas ether extract digestibility decreased in the BSF100 group(P<0.05).In comparison with BSF0,piglets from the BSF25 group showed a higher duodenal ratio of villus height to crypt depth,increased jejunal sucrase activity,serum neuropeptide Y and ghrelin levels,elevated ileal immunoglobulin(Ig)A,Ig G and Ig M contents and a lower leptin level,and piglets from the BSF100 group exhibited an increased relative weight of kidney(P<0.05).However,no significant differences were observed in the expression level of tight junction proteins and chitin-degrading ***,compared with BSF0,the abundance of short chain fatty acid producing bacteria such as Ruminococcaceae,Faecalibacterium and Butyricicoccus increased,and potential pathogenic bacteria decreased in piglets from the BSF25 group,whereas piglets from the BSF100 group had a greater abundance of harmful *** conclusion,BSF replacing 25%SBM in diets could improve digestive parameters,immune function and intestinal microbiota,and thus improved growth performance of ***,BSF replacing 100%SBM showed an adverse effect on piglet performance,and the reason might be related to the limited amount of chitin-degra

The offspring of super-multiparous sows face problems such as decreased growth performance,poor meat quality and even diseases in animal ***-aminobutyric acid(GABA)has long been known to promote growth and suppress inflammation,but little is known about the mechanisms.A total of 72 growing-finishing pigs from the 8th generation were randomly allotted to 2 groups with 6 replicates per treatment to receive a cornesoybean basal diet or the basal diet supplemented 20 mg/kg GABA for 60 *** the animal-trial period,samples of serum and liver were collected for further ***,a lipopolysaccharide(LPS)-induced inflammatory model using HepG2 cells was established to explore the role of GABA on regulating hepatic *** results indicated that inflammatory cell infiltration occurs in the liver of progeny of super-multiparous sows,and dietary supplementation with GABA influenced liver morphology,increased activities of antioxidant enzymes and decreased the expression abundance of pro-inflammatory cytokines,including tumor necrosis factor-α(TNFα)and interleukin(IL)-1β,in the liver of growing-finishing pigs(P<0.05).In addition,GABA supplementation increased mRNA expressions of peroxisome proliferator-activated receptor g(PPARg)and GABA receptors(GABARs),and reduced the expression of toll-like receptor 4(TLR4)/nuclear factor-kB(NF-kB)signaling(P<0.05).Additionally,an in vitro experiment demonstrated that GABA decreased the expressions of hepatic TLR4/NF-kB signaling via activating GABARs under LPS-stress(P<0.05).In summary,liver injury may affect the growth performance of growing-finishing pigs by changing hepatic mitochondrial metabolism,the expression of pro-inflammatory cytokines and TLR4/NF-kB pathway and that GABA supplementation has a restorative effect by acting on GABARs.
