【摘要】：通過給蘇淮斷奶仔豬飼喂微生態(tài)制劑(植物乳桿菌為主)研究其對斷奶仔豬生長性能、器官重及其胃腸道發(fā)育的影響,分析仔豬生長性能與器官重、小腸形態(tài)、腸道pH的相關(guān)性,探討微生態(tài)制劑緩解仔豬斷奶應(yīng)激的可能機(jī)制。選取健康、胎次和體重相近[(9.34±0.33)kg]的144頭28日齡蘇淮斷奶仔豬,隨機(jī)分為對照組(基礎(chǔ)日糧)、抗生素組(基礎(chǔ)日糧+抗生素)、微生態(tài)制劑組(基礎(chǔ)日糧+微生態(tài)制劑),每組6個(gè)重復(fù),每個(gè)重復(fù)8頭仔豬。預(yù)試期為3d,試驗(yàn)于32日齡開始,59日齡結(jié)束時(shí)屠宰采樣。結(jié)果表明,與對照組相比,微生態(tài)制劑可顯著提高斷奶仔豬平均日增重(ADG)和平均日采食量(ADFI)(P0.05),降低料重比(F/G)和腹瀉率(P0.05);顯著提高(P0.05)斷奶仔豬脾臟相對重量;顯著增加斷奶仔豬十二指腸絨毛高度(P0.05),顯著降低十二指腸、空腸、回腸絨隱比(P0.05),十二指腸、空腸、回腸隱窩深度有下降趨勢,但差異不顯著(P0.05);顯著降低(P0.05)斷奶仔豬盲腸、結(jié)腸pH。與抗生素組相比,微生態(tài)制劑組對各指標(biāo)無顯著影響(P0.05)。相關(guān)性分析顯示,ADG增加與肝臟相對重量增加顯著相關(guān)(P0.05);ADFI增加與十二指腸和脾臟相對重量、回腸絨隱比增加顯著相關(guān)(P0.05),與結(jié)腸和盲腸pH、回腸隱窩深度降低顯著相關(guān)(P0.05);F/G降低與結(jié)腸相對重量增加呈顯著相關(guān)(P0.05);腹瀉率下降與十二指腸相對重、脾臟相對重量、十二指腸和空腸絨隱比增加呈顯著相關(guān)(P0.05)。由此看出,微生態(tài)制劑可通過增加器官重,改善腸道形態(tài),降低胃腸道pH,提高斷奶仔豬生長性能、降低腹瀉率,緩解斷奶應(yīng)激對仔豬的影響,該微生態(tài)制劑具有替代抗生素的潛力。
[Abstract]:The effects of microecological preparation (Lactobacillus plantarum) on growth performance, organ weight and gastrointestinal tract development of weaned piglets were studied by feeding suhuai weaning piglets, and the growth performance, organ weight and intestinal morphology of piglets were analyzed. The correlation of intestinal pH and the possible mechanism of microecological preparation to relieve weaning stress in piglets were discussed. 144 28 day-old Suhuai weanling piglets with similar birth order and weight [9.34 鹵0.33 kg] were selected. They were randomly divided into control group (basal diet), antibiotic group (basic diet antibiotic group), microecological preparation group (basic diet microecological preparation group, 6 repeats in each group). The pretest period was 3 days, and the sample was slaughtered at the end of 59 days at the beginning of 32 days. The results showed that, compared with the control group, there was no significant difference between the two groups. The average daily gain (ADG) and average daily intake (ADFI) of weaned piglets were significantly increased by microecological agents, and the feed / weight ratio (F / G) and diarrhea rate were decreased, and the spleen relative weight of weaned piglets was significantly increased. The height of duodenal villus of weaned piglets was increased significantly (P0.05), and the ratio of duodenum, jejunum and ileum to crypt was significantly decreased, but the depth of duodenum, jejunum and ileum recess was decreased, but the difference was not significant (P0.05); the cecum of weaning piglets was significantly decreased. Compared with the antibiotic group, the colonic pH.had no significant effect on each index. The correlation analysis showed that the increase of ADG and the relative weight of liver were significantly correlated with the increase of ADFI and the relative weight of duodenum and spleen. There was a significant correlation between the increase of the ileal cashmere ratio and the pH of colon and cecum, the decrease of ileal recess depth, the decrease of P0.05 / G and the increase of relative weight of colon, the decrease of diarrhea rate was associated with the relative weight of duodenum and the relative weight of spleen. There was a significant correlation between duodenum and jejunum in the increase of chorion ratio (P 0.05). It was concluded that microecological preparation could increase organ weight, improve intestinal morphology, decrease gastrointestinal pH, improve growth performance and reduce diarrhea rate of weaned piglets. The microecological preparation has the potential to replace antibiotics.
