【摘要】：運(yùn)輸應(yīng)激是一種復(fù)雜的受多方面因素影響的應(yīng)激,羊在發(fā)生運(yùn)輸應(yīng)激后所表現(xiàn)的狀態(tài)一般被稱為運(yùn)輸應(yīng)激綜合征。運(yùn)輸應(yīng)激的發(fā)生會(huì)同時(shí)影響被運(yùn)輸羊的神經(jīng)-內(nèi)分泌系統(tǒng)、免疫功能、血液生理指標(biāo)、血液生化指標(biāo)以及生產(chǎn)性能。本試驗(yàn)以經(jīng)過(guò)長(zhǎng)途運(yùn)輸?shù)男∥埠驗(yàn)樵囼?yàn)動(dòng)物,以黃芪多糖粉和可溶性銀黃粉為試驗(yàn)藥物,采用飲水給藥的方式進(jìn)行了為期14d的緩解應(yīng)激試驗(yàn)。本試驗(yàn)通過(guò)測(cè)定經(jīng)過(guò)長(zhǎng)途運(yùn)輸后小尾寒羊在不同時(shí)間的各項(xiàng)與運(yùn)輸應(yīng)激相關(guān)的指標(biāo)以及發(fā)病情況和生產(chǎn)性能的變化,分析確定了試驗(yàn)藥物對(duì)小尾寒羊運(yùn)輸應(yīng)激有良好的緩解作用,同時(shí)確定了試驗(yàn)藥物的最適用量,為生產(chǎn)實(shí)踐中緩解羊的運(yùn)輸應(yīng)激同時(shí)減少經(jīng)濟(jì)損失提供了相應(yīng)依據(jù)。結(jié)果表明:經(jīng)過(guò)長(zhǎng)途運(yùn)輸試驗(yàn)羊在試驗(yàn)開(kāi)始階段均處在強(qiáng)烈的運(yùn)輸應(yīng)激狀態(tài)下,其各項(xiàng)生理生化指標(biāo)均未在正常范圍內(nèi)。隨著試驗(yàn)的進(jìn)行試驗(yàn)羊的應(yīng)激狀態(tài)開(kāi)始得到緩解。在生產(chǎn)性能方面,運(yùn)用試驗(yàn)藥物的試驗(yàn)組與未用藥的對(duì)照組相比小尾寒羊的采食量與體重增加量均有顯著的差異,最適用藥量試驗(yàn)組羊的料肉比為4.89,明顯優(yōu)于對(duì)照組的5.80,表明試驗(yàn)組羊的生產(chǎn)性能明顯好于對(duì)照組。試驗(yàn)羊在試驗(yàn)期間的血液生化指標(biāo)的變化顯示,最適用藥量試驗(yàn)組羊的各項(xiàng)相關(guān)生化指標(biāo)的恢復(fù)速度明顯好于對(duì)照組,其中以肌酸激酶、乳酸脫氫酶以及皮質(zhì)醇的含量變化最為顯著。試驗(yàn)羊運(yùn)達(dá)后的三大臨床指標(biāo)顯示,試驗(yàn)組小尾寒羊的體溫、脈搏和呼吸頻率的恢復(fù)速度均明顯優(yōu)于對(duì)照組,可以更快的恢復(fù)到正常水平。試驗(yàn)羊在試驗(yàn)期間的血液常規(guī)指標(biāo)的測(cè)定結(jié)果顯示,經(jīng)過(guò)運(yùn)輸后各組試驗(yàn)羊的白細(xì)胞總數(shù)均高于正常值,而淋巴細(xì)胞百分比卻明顯低于正常值,隨著試驗(yàn)的進(jìn)行白細(xì)胞總數(shù)開(kāi)始逐漸降低而淋巴細(xì)胞百分比開(kāi)始回升,最適用藥量試驗(yàn)組羊的白細(xì)胞恢復(fù)速度明顯優(yōu)于對(duì)照組。試驗(yàn)期間試驗(yàn)羊的呼吸道疾病發(fā)病率和消化道疾病發(fā)病率明顯降低,其中對(duì)照組羊的呼吸道疾病發(fā)病率和消化道疾病發(fā)病率分別為3.26%和4.59%,最適用藥量組試驗(yàn)羊的相應(yīng)發(fā)病率分別為1.12%和2.55%。結(jié)論:經(jīng)過(guò)長(zhǎng)途運(yùn)輸處于應(yīng)激狀態(tài)的小尾寒羊,通過(guò)黃芪多糖粉和銀黃可溶性粉的聯(lián)用可以調(diào)節(jié)其機(jī)體的生理功能,改善臨床指標(biāo)以及生理生化指標(biāo),在提高生產(chǎn)性能的同時(shí)降低發(fā)病率,對(duì)緩解羊的運(yùn)輸應(yīng)激有良好的效果。本試驗(yàn)中黃芪多糖粉和銀黃粉的最佳用量為黃芪多糖粉1.0g/只/天+銀黃可溶性粉1.0g/只/天,可作為生產(chǎn)應(yīng)用的參考劑量。
[Abstract]:Transport stress is a kind of complex stress affected by many factors. The state of sheep after transport stress is generally called transport stress syndrome. The occurrence of transport stress also affects the neuroendocrine system, immune function, blood physiological index, blood biochemical index and production performance of the transported sheep. A 14-day stress relief experiment was carried out in small tail Han sheep which was transported over a long distance. Astragalus polysaccharide powder and soluble silver yellow powder were used as experimental drugs. In this experiment, the indexes related to transport stress and the changes of incidence and production performance of small tail Han sheep at different time after long-distance transportation were measured. It is concluded that the experimental drugs have a good relieving effect on the transport stress of the small tail Han sheep and the most suitable quantity of the experimental drugs, which provides the corresponding basis for alleviating the transport stress and reducing the economic loss in the production practice. The results showed that after long distance transportation, the sheep were in the condition of strong transport stress at the beginning of the experiment, and their physiological and biochemical indexes were not within the normal range. As the experiment was carried out, the stress state of the sheep began to ease. In terms of production performance, the intake and weight gain of small tail Han sheep were significantly different between the experimental group and the control group. The ratio of feed to meat in the experiment group was 4.89, which was better than that in the control group (5.80), which indicated that the performance of the sheep in the test group was obviously better than that in the control group. The changes of blood biochemical indexes during the trial period showed that the recovery rate of the relative biochemical indexes of the test group was significantly better than that of the control group, in which creatine kinase was used as the main biochemical index. The contents of lactate dehydrogenase and cortisol changed most significantly. The three clinical indexes showed that the recovery speed of body temperature, pulse and respiratory frequency of the small tail Han sheep in the test group was obviously better than that in the control group, and could recover to the normal level more quickly. The results of blood routine test showed that the total number of white blood cells was higher than the normal value, but the percentage of lymphocyte was lower than the normal value. As the total number of white blood cells began to decrease and the percentage of lymphocytes began to rise, the recovery rate of white blood cells in the test group was obviously better than that in the control group. During the trial period, the incidence of respiratory and digestive tract diseases in sheep was significantly decreased. The incidence of respiratory tract disease and digestive tract disease were 3.26% and 4.59% in the control group, and 1.12% and 2.55% in the optimum dosage group, respectively. Conclusion: the combination of astragalus polysaccharide powder and silver yellow soluble powder can regulate the physiological function and improve the clinical indexes and physiological and biochemical indexes of small tail Han sheep under long distance transportation. At the same time, it can improve the production performance and reduce the incidence, which has good effect on alleviating the transport stress of sheep. The optimum dosage of astragalus polysaccharide powder and silver astragalus powder was 1.0g/ / 1.0g/ / day, which could be used as a reference dosage for production and application.
