奶牛肢蹄病的发病原因与防控要点分析

奶牛肢蹄病已成为现代奶牛饲养过程中,严重影响奶牛场经济效益的疾病之一。肢蹄病发生后,明显影响奶牛的运动和采食能力,影响奶牛产奶量和繁殖性能,严重者甚至被过早淘汰。本研究对奶牛肢蹄病的现状、发病原因等介绍分析,指出奶牛肢蹄病的发病原因有遗传因素、日粮营养因素、场地因素、管理因素、病原因素等,进而总结出防控本病的措施。在治疗方面,可以采取蹄部外用药和封闭疗法;在预防方面,要调整奶牛日粮结构,定期进行蹄浴,加强蹄部保健,加强日常管理工作,培育优良品种。     

奶牛蹄病的防治

在奶牛极易出现的几种疾病中,蹄病是影响较大的。据报道,夏、秋季节蹄病发病率较高,由于奶牛营养不均或饲养环境不当,均易发生此病。而且当饲养员在奶牛肢蹄保健方面出现疏忽大意时,肢蹄病也容易发生。发病时,奶牛的行走将受到很大的影响,若不治疗,疾病恶化还将导致奶牛出现下肢瘫痪,逐渐影响到奶牛的生产性能,给养殖场带来巨大的经济损失。     

奶牛肢蹄病的原因及防治措施

奶牛肢蹄病是导致奶牛淘汰的主要原因之一.受营养、管理、疾病、遗传等多方面因素的影响,奶牛可发生蹄部疾病而产生疼痛,表现为行走时蹄部无法受力而跛行,对奶牛健康影响极大.目前可通过营养调控、饲养管理及预防诊治等途径进行控制.     

浅析奶牛蹄病及蹄叶炎与腐蹄病的防治

正蹄病的防治在奶牛饲养中具有重要的意义,奶牛蹄病不仅能够导致奶牛的繁殖性能、产奶量和乳品品质降低,而且能使奶牛饲养医药成本和淘汰率增加,从而给奶牛饲养者造成较大的经济损失。奶牛蹄病的发生与遗传因素、圈舍环境、饲料营养、饲养管理、保健措施、病菌毒的感染及消化、生殖系统等疾病的继发密不可分,本文就奶牛蹄病的病因及防治进行浅析。1奶牛蹄病发生的原因(1)遗传直接决定牛对蹄病的易感程度,奶牛肢蹄     

奶牛蹄病的护理和中西医结合治疗

正奶牛蹄病是危害奶牛生产的三大疾病之一,是奶牛牧场养殖中比较常见的疾病,也是造成牧场牛只淘汰的重要原因之一,因蹄病淘汰的奶牛占4%~5%。奶牛蹄病临床上主要有蹄变形和腐蹄病两种。据报道,我国奶牛蹄病的发病率在30%以上,夏季炎热地区尤为严重。本病发生后奶牛蹄部疼痛不仅会影响发情,而且在治疗期间会导致弃奶和增加治疗费用,给奶牛生产造成较大经济损失。患本病的奶牛痊愈后,在后续的生产和繁殖方面,对奶产量和繁殖影响均较大。因此,预防奶牛蹄部疾病的发生,对提高奶牛养殖

Effect of age on serum chemistry profile, electrophoresis and thyroid hormones in beagle dogs two weeks to one year of age

Chemistry tests were conducted on serum from young Beagle dogs in order to deter mine the effect of age on these parameters. Blood was collected at regular intervals from 25 normal Beagle puppies (13 males and 12 females) at ages ranging from 2 weeks to 12 months. Serum chemistry profiles, protein electrophoresis and radioimmunoassays for thyroxine and triiodothyronine were included. Rapidly changing age related differences were observed in several parameters. Urea nitrogen, cholesterol, triglycerides, lactate dehydrogenase, thyroxine, glucose, gamma glutamyl transpeptidase, and total bilirubin values were elevated early in life, and decreased during the first 6 to 8 weeks, while alanine aminotransferase activity was low initially and increased during this period. Lactate dehydrogenase, thyroxine, gamma glutamyl transpeptidase, total bilirubin and alanine aminotransferase attained stability by 3 months, but the remaining parameters showed slight changes subsequently, gradually approaching adult values. More gradual age related changes were observed in other parameters. These included alkaline phosphatase, inorganic phosphorus and calcium values, which were higher in younger dogs, and creatinine, aspartate aminotransferase and total protein values, which were lower in younger dogs. Creatinine and aspartate aminotransferase values were stable by approximately 6 months; alkaline phosphatase, inorganic phosphorus, calcium and total protein values continued to change gradually up to 1 year.     

Concentrations of macro- and micro-elements in the milk of pasture-fed thoroughbred mares

OBJECTIVE: To determine the changes in Ca, P, Mg, Na, K, S, Cu, Fe and Zn concentrations of milk during the lactation in pasture-fed Thoroughbred mares and then calculate the dietary mineral requirements of the sucking foal and the lactating mare. PROCEDURE: Milk was sampled on days 1, 3, 7, 14, 21, 28 and at various times between 55 to 65, 85 to 95 and 135 to 150 days after parturition from 21 pasture-fed mares. The concentrations of macro- and micro-elements in the milk were determined by inductively coupled plasma emission spectrometry. RESULTS: Concentrations (mg/L) of these elements were highest in colostrum (Mg 302, Na 561, K 955, S 1035, Cu 0.76, Fe 0.79 and Zn 5.5) except for Ca (1245) and P (895), which where highest on day 7. The mean milk mineral element concentrations (mg/L) over days 55 to 150 were Ca 843, P 543, Mg 47, Na 120, K 590, S 219, Cu 0.19, Fe 0.34 and Zn 2.1. The mean plasma element concentrations (mg/L) over the same period were Ca 120, P 77.1, Mg 17.0, Na 3110, K 168, S 983, Cu 1.1, Fe 1.5 and Zn 0.49. Concentration gradients between plasma and milk were observed and, in the case of Ca, P, Mg, K and Zn, their concentrations in milk were greater than those in plasma, while a reverse situation was observed for Na, S, Cu and Fe. CONCLUSION: With the exception of Ca and P, the highest concentrations of mineral elements were observed in the colostrum. The nursing foal should have access to good pasture or creep feed, because the intakes of Ca, P and Cu from milk may be less than optimum to meet the daily mineral element requirements.
