Effect of Glycolysis and Emulsification Feed on Performance, Immunity and Dietary Nutrient Digestion of Lactating Sows
摘要
Abstract
In order to study the effects of glycolysis and emulsification feed on performance, immunity and di-etary nutrient digestion of lactating sow, a total of 160 sows ( Landrace×Yorkshine) with similar parity and due date were randomly assigned to 5 groups with 4 replicates in each group and 8 sows in each replicate. The 5 groups were control group, malt dextrin and glucose group, fermented soybean meal group, emulsifying fat group, and glycolysis and emulsification feed group. Sows in control group was fed a basal diet, and those in malt dextrin and glucose group, fermented soybean meal group, emulsifying fat group and glycolysis and emul-sification feed group were fed diets containing 1. 5% malt dextrin+1. 5% glucose, 5. 0% fermented soybean meal, 3.0% emulsifying fat and 10.0% glycolysis and emulsification feed, respectively. The experiment lasted for 34 days, which from begining of 108 days of pregnancy ( parturition in 114 days of pregnancy) , and at the end of piglet weaning of 280-day-old. The results showed as follows: 1) compared with the control group, malt dextrin and glucose group, fermented soybean meal group and emulsifying fat group, the average daily feed intake of lactating sows in glycolysis and emulsification feed group was increased by 7.08% (P<0.05), 5.88% (P>0.05), 5.78% (P>0.05) and 4.83% (P>0.05), after weaning to estrus interval of lactating sows was short by 26.58% (P<0.01), 15.94% (P<0.05), 10.77% (P<0.05) and 9.38% (P<0.05), average daily gain of weaning piglets was increased by 10.78% ( P<0.01) , 5.15% ( P>0.05) , 8.20% ( P<0.05) and 3.55% (P>0.05), and survival rate of 28-day-old piglets was increased by 6.14% (P<0.05), 0.78% (P>0.05), 2.09% (P>0.05) and 2.83% (P>0.05), respectively. 2) The content of serum immunoglobulin ( Ig) A, IgG, IgM and phytohemagglutinin ( PHA) lymphocyte transformation rate of lactating sows in glycol-ysis and emulsification feed group were increased by 23.93% (P<0.01), 39.17% (P<0.05), 19.28% (P<0.05) and 17.64% ( P<0.01) , respectively, while the content of serum cortisol was decreased by 5.97% ( P<0.05) than those in the control group. 3) Compared with the control group, the apparent digestibility of ether extract, organic matter and gross energy in glycolysis and emulsification feed group was significantly increased by 4.93%, 4.78% and 5.10%, respectively, and the differences were significant ( P<0.05) . The results indi-cate that glycolysis and emulsification feed can improve the lactating sow’ performance and apparent digestibil-ity of some dietary nutrients, and enhance immune function, especially in cellular immunity and humoral im-munity.关键词
