Abstract

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 ℃).Fifty-four multiparous sows(Landrace x Yorkshire;initial body weight of 236.3±16 kg;2,3 and 4 parities)at d 90 of gestation were assigned to a 2 x 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 and 120 min after the meal.The concentration of phthalic acid,succinic acid,phenylethylamine,hydro-cinnamic 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 temperature.Therefore,both soluble and insoluble sources of fiber are necessary to be added to the diet of gestating sows.
