Heat stress adversely affects sows' performance, which can be improved by applying proper nutritional strategies. This study was conducted to investigate the interactive effects of dietary fiber levels and sources on sows' reproductive performance, metabolic response during gestation, and the carry-over influence on litter performance in the lactation period during heat stress(average room temperature of 27.1°C). Fifty-four multiparous sows(Landrace × Yorkshire; initial body weight of 236.3 ± 16 kg; 2, 3and 4 parities) at d 90 of gestation were assigned to a 2 × 3 factorial arrangement(9 sows/treatment),involving 2 dietary fiber levels(4.5% and 6% crude fiber) and 3 dietary fiber sources(wheat bran [WB],palm kernel meal [PK], and beet pulp [BP]). Sows fed the BP diet had highest(P < 0.01) feed intake and constipation index and lowest(P < 0.01) farrowing duration. Piglet weight(P = 0.041) and litter weight(P < 0.01) at weaning were higher in sows in the BP treatment compared to PK treatment. Sows in the BP treatment showed the greatest(P < 0.01) digestibility of crude protein and neutral detergent fiber. The fecal concentration of acetate was the lowest(P < 0.01) in the PK treatment. Total short-chain fatty acid production was increased in the WB and BP treatments compared with the PK. Sows in the BP treatment showed the lowest(P = 0.036) hair cortisol. The blood insulin concentration of sows was higher(P = 0.026) in the high fiber(6%) treatment compared with the low fiber(4.5%) treatment at 90 min and120 min after the meal. The concentration of phthalic acid, succinic acid, phenylethylamine, hydrocinnamic acid, iron, linoleic acid, glycerol, ketone, and formamide were increased(P < 0.05) in the BP treatment compared with the WB. The BP treatment with high soluble fiber content improved the constipation index, farrowing duration, and litter performance, while high insoluble fibers increased sows comfort and reduced stress factors including respiratory rate and rectal

Background The study evaluated the effects of bacteriophage cocktail(BP)and ZnO administered during weaning time for piglets exposed to a non-sanitary *** bacteriophages were designed to eliminate Escherichia coli(K88,K99 and F41),Salmonella(typhimurium and enteritidis),and Clostridium perfreingens(types A and C).Forty 21-day-old crossbreed piglets were assigned to four treatments,including the PC(sanitary environment),NC(nonsanitary environment),BP(NC plus 108 pfu/kg BP),and ZO(NC plus 2,500 mg/kg ZnO).Piglets in the NC,BP and ZO were kept in a non-sanitary environment for 14 d,which was contaminated with the feces of infected *** Pigs in the BP and ZO treatments had a higher final body weight compared with the *** NC treatment showed the highest concentration of inflammatory cytokines including interleukin(IL)-1β,IL-6 and tumor necrosis factor-αin the *** administration of BP and ZO showed lower myeloperoxidase concentrations compared with the *** NC treatment showed a lower concentration of superoxide dismutase in serum compared with the *** the treatments in non-sanitary environment,the NC treatment showed a higher concentration of malondialdehyde compared with the *** PC treatment showed a lower concentration of butyric acid in the feces compared with the BP *** non-sanitary treatments,the villus height in the duodenum was greater in the BP and ZO compared with the *** lower abundance of Proteobacteria phylum was observed in the BP and PC treatments compared with the *** highest relative abundance of Eubacterium was recorded in the BP *** abundance of Megasphaera and Schwartzia was higher in the NC pigs compared with the BP *** abundance of Desulfovibrio was lower in the supplemented treatments(BP and ZO)compared with non-supplemented(NC and PC).The abundance of Cellulosilyticum genera was higher in the BP and ZO treatments rather than in the *** piglets in the NC treatment had the

The present study was conducted to test whether the dietary supplementation of β-mannanase affects amino acids(AA) digestibility,metabolizable energy(ME) contents of corn,wheat,soybean meal,distillers dried grains with solubles,and palm kernel meal(PKM),nutrient digestibility,and growth performance of *** Exp.1,22 cannulated pigs were used for 10 dietary treatments including 5 feed ingredients and 2 β-mannanase concentrations(0 and 0.5 g/kg of the diet) in 6 periods in an incomplete Latin square design to determine the AA and energy *** Exp.2,200 growing pigs were randomly allotted to 4 treatments with 2 nutrient levels(high and low) and 2 concentrations of β-mannanase(2×2 factorial arrangement) in 2 phases(phase 1,d 0 to 21;and phase 2,d 22 to 42).In Exp.1,β-mannanase increased the mean standardized ileal digestibility(SID) of AA in all feed *** amount of digestible energy was increased(P <0.05) in β-mannanase-treated *** fed β-mannanase showed a greater(P <0.05) digestibility of gross energy(GE).The feed-to-gain(F:G) ratio was improved(P <0.01) in pigs fed high-nutrient *** fed β-mannanase in the diets had greater(P <0.05) average daily gain and F:*** phase 2,the concentration of fecal ammonia was decreased(P <0.05) in pigs fed β-*** the 2 experiments,it can be concluded that β-mannanase increases the SID of AA,which has to be considered in balancing the rations.
