【摘要】：試驗(yàn)旨在研究日糧中添加啤酒酵母細(xì)胞壁(yeast cell wall extracts,YCWE)對母豬繁殖性能、乳成分和免疫指標(biāo)的影響。選取60頭體況相近的"長×大"經(jīng)產(chǎn)妊娠母豬(3~6胎),根據(jù)胎次和體況分成兩組,每組30個(gè)重復(fù),每個(gè)重復(fù)1頭母豬。對照組母豬飼喂基礎(chǔ)日糧,試驗(yàn)組母豬飼喂添加YCWE 1.5 g/kg的試驗(yàn)日糧。試驗(yàn)時(shí)間從母豬妊娠第1 d至哺乳21 d斷奶結(jié)束。結(jié)果表明:與對照組相比,日糧中添加YCWE顯著降低了母豬死胎數(shù)量和宮內(nèi)生長遲緩(Intrauterine growth retardation,IUGR)仔豬發(fā)生率(P0.05);顯著提高了活仔窩重、斷奶仔豬數(shù)和斷奶窩重(P0.05);活產(chǎn)仔豬數(shù)(P=0.10)和仔豬斷奶體重(P=0.07)有改善的趨勢。YCWE組顯著提高了母豬哺乳第10 d常乳中乳蛋白、乳糖和非脂固形物含量(P0.05),且哺乳第21 d乳中乳糖含量(P=0.08)仍然有提高的趨勢。此外,日糧中添加YCWE顯著提高了母豬初乳中免疫球蛋白Ig G、Ig M和哺乳第10 d常乳中Ig A、Ig M的濃度(P0.05)。結(jié)果表明:母豬妊娠期和哺乳期日糧中添加酵母細(xì)胞壁能顯著降低母豬死胎和IUGR仔豬發(fā)生率,并提高活產(chǎn)窩重;同時(shí),妊娠期和哺乳期日糧中添加酵母細(xì)胞壁還能通過改善母豬乳成分及提高母豬初乳和常乳中免疫球蛋白水平,提高哺乳期仔豬生長性能。
[Abstract]:The purpose of this study was to study the effects of the addition of yeast cell wall extensions (YCVE) on the reproductive performance, milk composition and immune index of sows. The "long and large" with similar body conditions was selected to be divided into two groups according to the fetal and body conditions, and each group was divided into two groups according to the fetal and body conditions, each of which was 1 sow. The control group was fed with the basal diet, and the test group was fed with the test diet supplemented with YCVE 1.5 g/ kg. The duration of the test was the end of weaning from the first day of gestation to the second day of lactation of the sow. The results showed that, compared with the control group, the addition of YCVE in the diet significantly reduced the number of stillbirth and IUGR in the sows (P0.05), and significantly increased the number of live litter, the number of weaned piglets and the weight of weaned piglets (P0.05). The number of live-born piglets (P = 0.10) and the weaned weight of the piglets (P = 0.07) had an improved tendency. In the YCVE group, the milk protein, lactose and non-fat solid content in the 10-d normal milk of the sows were significantly increased (P0.05), and the lactose content (P = 0.08) in the 21-d milk of the lactation period was still improved. In addition, the addition of YCVE in the diet significantly increased the concentration of Ig A and Ig M in the normal milk of the sow's colostrum (P0.05). The results showed that the addition of yeast cell wall to the diet of sows during pregnancy and lactation could significantly reduce the incidence of the stillbirth and IUGR piglets in the sows, and increase the weight of live births. The addition of yeast cell wall in the diet of pregnancy and lactation can improve the growth performance of the piglets by improving the milk composition of the sow and improving the level of the immunoglobulin in the colostrum and the normal milk of the sow.
