鹅流行性感冒又称鹅流感、鹅出血性败血症,是由败血志贺氏杆菌引起的一种渗出性和败血性传染病.该病传染性强,发病率和死亡率高,鹅易感,鸡、鸭不易感.鹅大肠杆菌病是由致病性大肠杆菌感染所引起的一种致死性强的传染病.雏鹅感染多呈现急性败血症死亡,产蛋鹅多感染生殖系统、表现为卵巢炎、输卵管炎和卵黄性腹膜炎.由于大肠杆菌血清型众多,所以该病一般很难选择疫苗免疫,有条件的大型养殖场可以选择自家苗免疫.鹅巴氏杆菌病又称鹅霍乱或出血性败血症,是由多杀性巴氏杆菌感染鹅引起的一种急性败血性传染病.

牛支气管炎是因恶劣的外部环境条件、温度变化、吸入刺激性气体或是内外源非特异性细菌大量繁殖等因素,使牛的支气管黏膜防御机能减弱,诱发本病.在此从牛支气管炎的病因、诊断及防治措施等方面进行探讨. 1 发病原因 1.1 气候因素 牛支气管炎一般均在早春和晚秋发病,由于此时温度低且温差较大,致使牛呼吸道黏膜血管收缩,牛容易受到流感病毒的侵袭,特别是犊牛和弱牛易发病,低温还可使牛吸入气体温润不足,机体含水量减少,呼吸不畅、形成痰液黏稠、肺脏功能减弱,从而导致牛支气管炎的发生.

阴道肿瘤是母犬生殖器官的一种常见肿瘤,其阻塞产道,影响犬的生长繁殖性能,严重者可造成母犬丧失配种和繁育能力.近年来,犬阴道肿瘤的发病率呈上升趋势. 阴道肿瘤又称阴道息肉,是母犬生殖器官的一种常见肿瘤,占犬生殖道肿瘤的64％左右[１].母犬阴道肿瘤最常见平滑肌瘤和传播性性病肿瘤,其他肿瘤有纤维瘤、纤维肉瘤、神经纤维瘤、网状纤维肉瘤、鳞状细胞癌和淋巴肉瘤等[2].近年来,随着养犬数量的增加,母犬阴道肿瘤的发病率亦越来越高.目前,对于犬的阴道肿瘤的治疗主要以手术切除为主,辅助抗肿瘤药物治疗为辅.

<正>2012年春季,公主岭市桑树台镇多个猪场的断奶前后小猪发生了一种以体温升高、咳嗽、腹式呼吸、进行性消瘦为主,母猪不食、流产、呼吸困难,为主要临床症状的传染病,经过流行病学调查,临床症状和剖检变化及实验室检验。鉴定为胸膜肺炎放线杆菌和肺炎支原体混合感染。通过采取综合防制措施,病情得到有效控制。1流行病学调查2012年春季来得较晚,东北地区有倒春寒的情况,在较冷的几天里,刚开始有打喷嚏、流鼻涕的情况,按感冒治疗无效。调查的10个猪场中,断奶仔猪和育肥猪发病率高,最高达70%,母猪发病率也较高,高达50%,死亡率也达50%,病程较长可达2～3周。

120 Duroc×Landrace×Yorkshire growing-finishing pigs were divided into three groups randomly in this single factor test trial.The control group Ⅰwas fed with basal diet and the control groupⅡwas fed with basal diet plus antibiotics,and the experimental group was fed with basal diet added SOPIS(Soybean Oligosaccharides,Peptides,Isoflavones and Saponins).The result of feeding trial indicated that compared with control groupⅠSOPIS remarkably improved daily gain,feed/gain as well as diarrhea rate.Furthermore,three indexes of the experimental group was the same as control groupⅡ.According to the results obtained from this study we can draw the conclusion as follows: adding SOPIS in growing-finishing pig diet can completely substitute antibiotics feed additive.

多杀性巴氏杆菌是鹅霍乱的病原体,给我国养鹅业带来了巨大的经济损失,但尚无有效的预防和控制措施。本试验对吉林地区分离的巴氏杆菌分离株的培养特性、生化特性、对化学消毒剂的敏感性、致病性、药敏试验进行了研究。结果为生化特性符合巴氏杆菌特性;1:10000稀释的百毒杀和1:5000稀释的过氧乙酸可有效杀灭该菌;对小鼠有较强致病性;药敏试验结果表明对氟苯尼考、氨苄西林、阿莫西林敏感,这将为研制巴氏杆菌灭活疫苗奠定了重要基础。

<正>农村养猪,多以分散饲养为主,近年由于生猪市场看好,很多养猪户扩大饲养规模,向规模化发展,由于饲养管理水平低,防疫观念差,生猪及其产品流通频繁,加之规模扩大而忽视了环境污染。所以农村的猪病流行呈上升趋势。笔者在乡镇畜牧兽医站工作多年,在技术服务中,总结了农村猪病

Objective:Newcastle Disease (ND) is often taken in the birds, the disease is serious and difficult to permanently cure, the most ideal preventing and controlling method is the vaccine immunity. Survey and evaluate NDV Antibody from layer serum, yolk and chicks was determined by Hemagglutination Inhibition test(HI) and ELISA in this study and research. The deamplification regularity of antibody was observed, the ND antibody titer was 1:64 ～ 128 for 1 ～ 3 days chicks, but it decreased gradually with time-lapse, the titer of 18 days chicks ND antibody decreased below 1:4. The half life was 4 ～ 5d. Three effective immune procedures were examination to 3 days chicks with antibody level 1:40. Discovered the 2nd group of immune procedure is more ideal.

鸡大肠杆菌病是危害肉鸡饲养业的主要细菌性疾病之一,是由致病性鸡大肠杆菌引起的条件性疾病,主要临床表现为下痢、脐带炎、心包炎、肝周炎、气囊炎、腹膜炎,个别鸡还表现肿头、关节炎等症状.本病极易与鸡球虫病、鸡新城疫、鸡慢性呼吸道病发生混合感染,使病情复杂化,给防治工作增加难度,从而给养殖户造成较大的经济损失.
