The treated slices were subjected for drying in different modes of drying （oven, microwave oven and cabinet tray drying） and analyzed for various physico-chemical and organoleptic quality characteristics. The study revealed that the osmo-air dried slices of mango produced with partial dehydration facilitated by osmotic agent （sugar syrup of 60 °Brix. A fruit： sugar syrup ratio of 1：4 （w/v） for 18 h at 40 ℃ temperature） followed by mechanical drying showed superiority in sensorial quality attributes over other concentrations of ingredients and the rest of the modes of drying. The good quality osmotically dehydrated mango slices could be preserved with maximum retentions of vitamins with better dehydration, rehydration and sensorial quality characteristics.展开更多

Sixty Large White × Landrace primiparous sows were divided into four groups （fifteen sows per group）. The control group was fed with basal diet, the others were fed with basal diet supplemented with 0.02%, 0.04% and 0.06% PFA, respectively. Compared with the control, the sows in 0.04% PFA group had higher feed intake during lactation and higher litter weaning weight （P 〈 0.05）. At farrowing, glucose level in 0.04% PFA sows was higher than the control and sows in 0.02% PFA had the highest IgG content among the treatments （P 〈 0.05）. On day 7 of lactation, serum urea nitrogen contents were lower in response to PFA supplementation compared to the control （P 〈 0.05）. At the same time, sows fed the 0.06% PFA diet increased the lysozyme activity （P 〈 0.05）. The levels of milk lactose and IgG were increased in 0.02% and 0.04% PFA groups （P 〈 0.05）. In conclusion, feeding PFA improved sows and litter performance, serum metabolite concentrations, lgG level and lysozyme activity at postpartum and milk quality.展开更多
