母猪喂服中药"黄白痢散"对仔猪黄白痢的预防效果 总被引：4，自引：0，他引：4
根据中兽医辨证施治理论，选择了穿心莲、白头翁等中草药配成预防仔猪黄白痢的制剂“黄白痢散”，通过拌料喂服母猪进行了预防仔猪黄白痢的试验。18头胎次、体重、年龄、分娩期相近的待产母猪随机分为3组，一组为对照组(CK)，其余两组为处理组，两个处理组的母猪从产前5—7d开始，每头每天分别喂50g和100g黄白痢散1次，产后l一2d连喂2次，之后每隔7d再喂1次，直至断奶。结果表明：(1)“黄白痢散”煎剂在平板对所分离的大肠杆菌的平均抑菌圈直径为14．3mm；(2)添加“黄白痢散”的两个处理组分别获得83．22％和94．29％的保护率，效果显著(P＜0．01)，与CK相比，处理组黄白痢发病率分别下降了46．10％和58．06％，平均断奶窝重分别提高8．8lkg和11．06kg，而窝收益分别增加98．22元和l17．22元。由此可见，通过母猪饲料喂服“黄白痢散”，对大肠杆菌有一定的抑菌效果，可有效预防仔猪黄白痢，有显著的经济效益。 相似文献

为研究发酵型生乳散对母猪及仔猪生产性能的影响,采用单因子试验法,选体况相近、妊娠95 d的母猪120头,随机分为4组,每组3个重复,每个重复10头,分别为空白对照组和试验Ⅰ、Ⅱ、Ⅲ组。对照组饲喂基础日粮,Ⅰ、Ⅱ、Ⅲ组在饲喂基础日粮的同时,分别投喂生乳散(10 g/头/d)、发酵型生乳散(10 g/头/d)、乳酸菌(10 mL/头/d),自母猪妊娠第95天开始投喂,至产后21 d结束。试验期间统计母猪生产性能及仔猪生长性能的指标,并测定仔猪20日龄时血清抗氧化指标。结果表明:(1)与对照组相比,试验Ⅰ、Ⅱ、Ⅲ组平均窝活仔数、窝断奶仔猪数及仔猪平均断奶重均显著提高(P0.05),妊娠后期便秘率及哺乳仔猪腹泻率大幅降低,其中又以Ⅱ组的各项指标最优(P0.05);(2)Ⅱ组母猪断奶7 d内发情率和情期受胎率均为100%,优于其他试验组;(3)Ⅱ组仔猪总抗氧化能力(T-AOC)、过氧化氢酶(CAT)、谷光甘肽过氧化酶(GSH-P_X)及超氧化物歧化酶(SOD)均显著高于其他试验组,丙二醇(MDA)显著低于其他试验组(P0.05)。综上所述,发酵型生乳散能显著提高母猪和仔猪的生产性能与健康状况,增强仔猪血清抗氧化能力,其整体作用效果优于未发酵生乳散和乳酸菌。 相似文献

This study was conducted to measure the concentrations of strontium (Sr), barium (Ba), cadmium (Cd), copper (Cu), zinc (Zn), manganese (Mn), chromium (Cr), antimony (Sb), selenium (Se), and lead (Pb) in canine liver, renal cortex, and renal medulla, and the association of these concentrations with age, gender, and occurrence of chronic kidney disease (CKD). Tissues from 50 dogs were analyzed using inductively coupled plasma mass spectrometry. Cu, Zn, and Mn levels were highest in the liver followed by the renal cortex and renal medulla. The highest Sr, Cd, and Se concentrations were measured in the renal cortex while lower levels were found in the renal medulla and liver. Female dogs had higher tissue concentrations of Sr (liver and renal medulla), Cd (liver), Zn (liver and renal cortex), Cr (liver, renal cortex, and renal medulla), and Pb (liver) than male animals. Except for Mn and Sb, age-dependent variations were observed for all element concentrations in the canine tissues. Hepatic Cd and Cr concentrations were higher in dogs with CKD. In conclusion, the present results provide new knowledge about the storage of specific elements in canine liver and kidneys, and can be considered important reference data for diagnostic methods and further investigations. 相似文献

Breed differences for weight (CW), height (CH), and condition score (CS) were estimated from records (n = 12,188) of 2- to 6-yr-old cows (n = 744) from Cycle IV of the U.S. Meat Animal Research Center's Germplasm Evaluation (GPE) Program. Cows were produced from mating Angus and Hereford dams to Angus, Hereford, Charolais, Shorthorn, Galloway, Longhorn, Nellore, Piedmontese, and Salers sires. Samples of Angus and Hereford sires were 1) reference sires born from 1962 through 1970 and 2) 1980s sires born in 1980 through 1987. The mixed model included cow age, season of measurement and their interactions, year of birth, pregnancy-lactation code (PL), and breedgroup as fixed effects for CW and CS. Analyses of weight adjusted for condition score included CS as a linear covariate. The model for CH excluded PL. Random effects were additive genetic and permanent environmental effects associated with the cow. Differences among breed groups were significant (P < 0.05) for all traits and were maintained through maturity with few interchanges in ranking. The order of F1 cows for weight was as follows: Charolais (506 to 635 kg for different ages), Shorthorn and Salers, reciprocal Hereford-Angus (HA) with 1980s sires, Nellore, HA with reference sires, Galloway, Piedmontese, and Longhorn (412 to 525 kg for different ages). Order for height was as follows: Nellore (136 to 140 cm), Charolais, Shorthorn, Salers, HA with 1980s sires, Piedmontese, Longhorn, Galloway and HA with reference sires (126 to 128 cm). Hereford and Angus cows with reference sires were generally lighter than those with 1980s sires. In general, breed differences for height followed those for weight except that F1 Nellore cows were tallest, which may in part be due to Bos taurus-Bos indicus heterosis for size. 相似文献

In experiment 1, 6 pregnant mares received a concentrate that contained a trace mineral premix that provided 14.3 mg Cu, 40 mg Zn, 28 mg Fe, 28 mg Mn, 0.08 mg Co, 0.16 mg I, and 0.16 mg Se/kg concentrate (group A). Seven mares received the same concentrate plus 502 mg Zn and 127 mg Cu once daily (group B). No differences (P > .05) in foal growth data, or Cu, Zn, and Fe concentrations of mare milk, mare serum, or foal serum were observed. In experiment 2, 6 pregnant mares received the same concentrate as group A (group C), and 8 mares received the same concentrate fortified with 4× the trace mineral premix (group D). Group C mares had higher serum Zn concentration at 1 day (P < 0.01) and 56 days (P < 0.04). Group C mares had higher milk Fe concentration at 28 days (P < .01), and group D mares had higher milk Cu concentration at 56 days (P < .01). Group C foals had higher serum Cu concentration at 14 days (P < .03). The results from this study provide no evidence to indicate that supplementing late gestating and lactating mares with higher dietary trace mineral levels than those recommended currently by NRC has any influence on foal growth and development, or on the Cu, Zn, and Fe concentrations of the mare milk, mare serum, or foal serum. 相似文献

A simple two step procedure for the isolation of caprine, ovine, bovine, equine, canine, porcine and human peripheral blood granulocytes is described. After enrichment of granulocytes by centrifugation, contaminating erythrocytes are lysed hypotonically. Recovery, purity, and viability of the granulocyte suspensions are determined. FACScan analysis of the cell suspensions measuring cellular size by forward and sideward light scatter is compared with the corresponding analysis of whole blood leukocytes. Constituencies of the isolated cell suspensions and loss of granulocyte subpopulations through isolation procedure is discussed with regard to granulocyte function assays. 相似文献

The present context investigated the comparative study on the supplementation of antibiotic, probiotic, organic acid, vitamin C, and herbal extract after vaccination into drinking water and their effects on performance, carcass quality, blood biochemical parameters, immune system, and intestinal flora in broiler chicks for 42 days. A total of 420 one-day-old male broiler chicks (Ross 308) were randomly assigned into 7 treatments with 3 replicates (pens) per treatment and 20 male chicks for each replicate (pen). The experimental treatments consisted of drinking water (control, without additive); drinking water + antibiotic sulfamet; drinking water + C-Vet-50; drinking water + antibiotic sulfamet + C-Vet-50; drinking water + probiotic Primalac; drinking water + butyric acid; and drinking water + extract of Echinacea purpurea Moench (coneflower). There were no differences observed among the treatments for feed intake, but during the whole experimental period, the highest body weight gain was found in the chicks fed with drinking water + antibiotic sulfamet + 50 cc vitamin C (P < 0.05). There were no differences (P > 0.05) observed among the treatments for feed conversion ratio (P > 0.05). Moreover, there were no differences reported among treatments for carcass characteristics at the end of the experiment. Among the treatments, drinking water + 50 cc vitamin C, and drinking water + extract of E. purpurea reduced (P < 0.05) the levels of cholesterol, triglycerides, and low-density lipoproteins. Drinking water + 50 cc vitamin C, drinking water + Primalac, and drinking water + extract of E. purpurea increased (P < 0.05) the lymphocytes count and decreased the heterophils count and heterophil:lymphocyte ratio. The highest Escherichia coli count and lowest Lactobacillus count in ileal content of the broilers were observed in the control group (P < 0.05). The additives used in this study may be incorporated in the drinking water of broiler chickens as growth promoters and for improved performance. A further, wider supplementation study is required to understand the performance, immune system, variation in the intestinal microbial counts, and any other possible alteration in the intestinal biota of the broilers. 相似文献

Circular excised skin wounds in the thoracic and metatarsal regions of the dog were studied. A similar sequence of events took place in the two regions although differences did occur due to the different reactions of the tissues which surrounded the wounds. None of the wound cavities became filled with exudate during the early stages of healing. In the thoracic wounds the cavities were largely filled by the swelling and inward movement of adipose tissue. Epithelium first grew on the wound surface in the sector of the wound that was situated in the direction of hair flow. The average time to complete epithelization was similar in both sets of wounds. A zone of alopecia developed around the wounds. 相似文献
