【摘要】：研究了肉桂醛制剂替代保育猪和生长前期猪饲粮中抗生素类饲料添加剂的效果。本研究包括试验1和试验2两个试验,试验1研究了肉桂醛制剂替代保育猪饲粮中金霉素、杆菌肽锌合剂的效果；试验2探讨了肉桂醛制剂替代生长前期猪饲粮中粘杆菌素和杆菌肽锌合剂的效果。试验1选取180头42日龄健康的杜×长×大三元杂交保育猪,按照体重相似和性别比例相同的原则将其分为三组,即对照组、试验A组和试验B组。每组60头猪,分为4个重复,每个重复15头猪。对照组猪被喂以猪场常规的保育猪饲粮,其中含有多种抗生素；分别用肉桂醛制剂A和B取代猪场常规的保育猪饲粮中金霉素和杆菌肽锌合剂,而后相应地喂试验A组猪和试验B组猪。肉桂醛制剂A在保育猪饲粮中添加量为400mg/kg；肉桂醛制剂B在保育猪饲粮中添加量为600mg/kg。饲养试验周期为21天。饲养试验结果如下：用肉桂醛制剂A和B替代保育猪饲粮中联用的金霉素和杆菌肽锌,可显著降低保育猪的腹泻率和腹泻指数(P0.05)。试验A、B组猪增重和饲料转化率都较对照组高,其中试验B组猪增重提高幅度达到显著的程度(P0.05)。试验B组猪血清总蛋白含量显著(P0.05)地高于对照组；试验A、B组猪血清GPT活性低于对照组,其中试验B组达到显著(P0.05)的水平；试验B组猪血清GOT活性显著(P0.05)地高于对照组和试验A组；试验A、B组猪血清SOD、CAT、GSH-Px活性和T-AOC显著(P0.05)或极显著(P0.01)地高于对照组；试验A、B组猪血清MDA含量极显著(P0.01)地低于对照组。试验A、B组猪瘟抗体、猪蓝耳抗体、猪圆环病抗体水平都不同程度地高于对照组,达到显著的水平(P0.05)；试验B组猪伪狂犬抗体水平显著地高于对照组(P0.05)。试验2选取180头63日龄健康的杜×长×大三元杂交生长前期猪,按照体重相似和性别比例相同的原则将其分为三组,即对照组、试验A组和试验B组。每组60头猪,每组4个重复,每个重复15头猪。对照组猪被喂以生长前期猪常规饲粮,其中含有粘杆菌素和杆菌肽锌合剂；分别用肉桂醛制剂A和B替代生长前期猪常规饲粮中抗生素粘杆菌素和杆菌肽锌合剂,而后相应地喂试验A组猪和试验B组猪。肉桂醛制剂A在生长前期猪饲粮中添加量为400mg/kg；肉桂醛制剂B在生长前期猪饲粮中添加量为600mg/kg。饲养试验周期为28天。饲养试验结果如下：试验A和B组猪的腹泻率和腹泻指数显著地(P0.05)降低；增重和饲料转化率显著地(P0.05)提高；血清TP含量、CAT、SOD、GSH-Px活性和T-AOC均不同程度地高于对照组(P0.05或P0.01),血清MDA含量显著(P0.05)或极显著(P0.01)地低于对照组,试验A、B组猪血清GPT活性低于对照组,其中试验B组达到显著(P0.05)的水平：血清中猪瘟、蓝耳病抗体、伪狂犬病抗体和猪圆环抗体水平都显著地高于对照组(P0.05),试验B组猪口蹄疫抗体水平高于对照组(P0.05)。试验A组猪口蹄疫抗体和IgG含量都不同程度地多于对照组。试验1,2中三组猪血清Glu、UN含量以及GOT活性无显著的差异(P0.05)。根据以上的试验结果可推断：①肉桂醛制剂能替代保育猪饲粮中金霉素、杆菌肽锌合剂和生长前期猪饲粮中粘杆菌素、杆菌肽锌合剂,且肉桂醛制剂的应用效果更好。②肉桂醛制剂能有效地预防控制猪的腹泻病的发生。③肉桂醛制剂对保育猪和生长猪具有促生长和提高饲料转化率的作用。④肉桂醛制剂能显著地改善猪体营养生化代谢。⑤肉桂醛制剂B的应用效果比肉桂醛制剂A更好。
[Abstract]:The effect of cinnamaldehyde on the substitute for the antibiotic feed additive in the pig and the pre growth pig diet was studied. This study included the experiment 1 and the experiment 2 two experiments, and the experiment 1 studied the effect of cinnamaldehyde on the substitution of the chlortetracycline and bacilli zinc mixture in the diet of the protected pig; and the test 2 studied the cinnamaldehyde preparation instead of the prophase pig feeding. The effect of the mixture of Bacillus mucinin and Bacillin zinc mixture in the diet. 1 selected 180 head 42 days old Du x long x large three yuan hybrid pigs were divided into three groups according to the principle of weight similarity and the same sex ratio, that is, the control group, the test A group and the test B group. Each group of 60 pigs was divided into 4 repetitions, each repeated 15 pigs. The control group was fed to the pigs. The conventional preserved pig diet contained a variety of antibiotics, with cinnamaldehyde preparation A and B, respectively, to replace A and B in the pig farm, and then feed the A group pigs and test B pigs. The cinnamaldehyde preparation A was added to the protected pig diet, and the cinnamaldehyde preparation B was fed in the pig feed. The experiment period of adding 600mg/kg. in grain was 21 days. The results of feeding test were as follows: using cinnamaldehyde preparation A and B to replace the combined use of chlortetracycline and bacilli zinc in the Fed pig diet, the diarrhea rate and diarrhea index (P0.05) of the protected pigs were significantly reduced. The test A, the pig weight gain and the feed conversion rate of the B group were higher than those of the control group, of which the B group was tested in the B group. The total protein content in the test group B was significantly higher (P0.05). The serum total protein content of the pig was significantly higher than the control group (P0.05). The test A, the GPT activity of the pig serum in the B group was lower than the control group, of which the test B group reached a significant level (P0.05); the test B group of serum GOT activity (P0.05) was higher than that of the control group and the experimental A group. Serum SOD, CAT, GSH-Px activity and T-AOC significantly (P0.05) or extremely significant (P0.01) higher than the control group; test A, B group pig serum MDA content is significantly lower than the control group. Test A, B group swine fever antibody, porcine blue ear antibody, porcine circate antibody level is higher than the control group, reaching a significant level The level of rabies antibody was significantly higher than that of the control group (P0.05). Test 2 selected 180 heads of 63 days old and 63 day old hybrids. According to the principle of weight similarity and sex ratio, they were divided into three groups, that is, the control group, the test group A and the test B group. Each group of 60 pigs, each group of 4 repeats, each repeated 15 pigs. The control group of pigs. The normal diet of pre growth pigs was fed with the mixture of Bacillin and bacilli zinc, and the A and B of cinnamaldehyde were used to replace the antibiotic Mycobacterium and bacilli zinc mixture in the routine diet of porcine pre growth, and then the pigs in the A group and the test B group were fed in the A group. The dosage of cinnamaldehyde, A, was 400mg/ in the pre growth pig diet. Kg; cinnamaldehyde preparation B was added to the pre growth porcine diet for 28 days. The results of the feeding test were as follows: the diarrhea rate and diarrhea index of the pigs in the A and B groups were significantly decreased (P0.05), the weight gain and feed conversion rate were significantly increased (P0.05), and the serum TP content, CAT, SOD, GSH-Px activity and T-AOC were different degrees. The serum MDA content was significantly higher than that of the control group (P0.05 or P0.01), and the serum MDA content was significantly (P0.05) or significantly lower than the control group. The test A and B group were lower than the control group, and the experimental B group reached a significant level (P0.05): the serum levels of swine fever, blue ear disease, pseudorabies antibody and hog antibody were significantly higher than those of the control group (P0.0). 5) the level of FMD antibody in the test group B was higher than that of the control group (P0.05). The test of pig foot and mouth disease antibody and IgG content in group A were more than the control group. There was no significant difference between the serum Glu, UN content and GOT activity in the test group 1, 2 (P0.05). The results of the above test can be concluded: (1) cinnamaldehyde can be used as a substitute for the Fed pig diet. Chlortetracycline, bacilli zinc mixture and prophase porcine diet, Bacillin, bacilli zinc mixture, and cinnamaldehyde have better application effect. (2) cinnamaldehyde preparation can effectively prevent and control the occurrence of diarrhea in pigs. (3) cinnamaldehyde has a role in promoting growth and raising feed conversion rate for protected and growing pigs. (4) cinnamaldehyde The preparation can significantly improve the nutritional and biochemical metabolism of pigs. Cinnamaldehyde B is better than cinnamaldehyde A.
