日本养鸡产业的一体化经营模式

日本蛋鸡产业的一体化主要由作为龙头企业的孵化场和饲料加工厂为源头展开的。这些龙头企业采用的模式是委托养鸡农户加工生产。根据龙头企业的类型来分,日本的养鸡产业一体化可以分为（1）孵化场型的一体化;（2）鸡蛋批发商型一体化;（3）饲料商社型一体化;（4）综合商社型一体化;（5）农协型一体化。（1）孵化场型的一体化：孵化场采用合同的方式委托农户养鸡。孵化场向合同农户提供建设鸡舍的图纸,教授饲养的技术。农户按照龙头企业提供的资料和技术,建造鸡舍,养鸡,然后龙头企业派专车到农户农场回收鸡蛋。孵化场的一体化的特点是,龙头企业把农户的合同生产同自己生产总计划连接起来。     

探究日本养鸡业一体化经营模式

或许你不会相信,在日本买1千克普通冬笋的钱足可以买上10千克鸡肉,但是不由你不信,因为这是事实。 众所周知,日本的劳动力成本很高,那么他们为什么能生产出价格如此低廉的鸡肉呢?这就有赖于他们已经形成的低成本运作的一体化经营模式。     

美国养鸡产业一体化经营模式

发达国家养鸡产业经过多年的发展,其生产水平已跃升到一个很高的台阶。特别是在养鸡实践中不断形成与逐步完善的一体化经营模式,对丰富我国现有的以“公司 (基地) 农户”为主的模式将起到极其巨大的促进作用。     

山西省蚕桑产业一体化经营模式构建

根据蚕桑产业一体化经营模式有关理论及原理,结合山西的实际情况,重点构建了4种适合各个不同发展阶段的山西省蚕桑产业发展模式。即：“蚕技中心＋农户”模式,“蚕技中心＋基地＋农户”模式,“丝厂（市场）＋蚕桑协会＋农户”模式,“公司（市场）＋蚕农合作社＋农户”模式。

韩国糕点食品添加剂问题波及养鸡产业

最近糕点业界由于添加剂问题，消费对糕点的恐惧已经波及到养鸡业界。 4月8日韩国KBS的追踪60分节目上，播出了名为“糕点的恐怖，威胁我们的健康”的报道，报道指出糕点可诱发甚至加重过敏性皮炎，自此之后，韩国的糕点及鸡蛋的销售出现明显下降。

肉鸡难养,从管理中找缺陷

一、养殖环境的优化问题:鸡舍布局不合理,排污设施不完善,多数养殖户间相互串门,进出鸡舍不采取必要的消毒措施,鸡舍无通风换气设施,鸡舍简陋,隔热保温性能差,多数鸡场不绿化、不硬化,裸露于风吹日晒之下,舍内条件差.     

Footpad dermatitis in broiler chickens in Japan

The prevalence of footpad dermatitis (FPD) in broiler chickens in Japan was investigated. In the first examination at slaughterhouses, lesions were commonly observed on the footpads of a total of 8,985 broiler chickens from 45 flocks on 36 farms. In 3 flocks, all the birds examined had lesions. In the other 42 flocks, the incidence of FPD ranged from 31.9% (81/254) to 99.5% (1/222). The footpad lesions were classified into 4 categories according to the severity of dermatitis as follows; score 0, 1,181 birds (13.1%); score 1, 2,992 birds (33.3%); score 2, 3,000 birds (33.4%); and score 3, 1,812 birds (20.2%). The mean scores of the flocks varied widely from 0.31 to 2.69. Males had higher mean scores than females. No significant differences were found between the mean scores of birds reared in windowless houses and those in open-sided houses. On 4 farms, the investigation was carried out in different seasons, and 3 of them showed higher mean scores in winter than in summer. Next, observation of 2,255 birds from 15 flocks on 5 farms during a 4-week rearing period revealed that FPD was already produced at 7 days of age and worsened with age.     

Pathology of listerial encephalitis in chickens in Japan

Neural signs (torticollis, drowsiness) and mortality were observed in five chickens of a native chicken flock (reared for meat) that included 450 male birds on a farm that had 2300 native chickens and 1120 layers. Histologic lesions were observed in the medulla oblongata, optic lobe, cerebellum, and spinal cord of the affected birds. The lesions, which were most severe in the medulla oblongata, were massive abscesses with rarefaction (demyelination and malacia) of the parenchyma with gram-positive bacteria. The degenerative and necrotic areas were characterized by fibrin thrombosis, hemorrhages, and congestion in the blood vessels. Immunohistochemically, the bacteria positive for L. monocytogenes antigen were observed in the medulla oblongata, cerebellum, and spinal cord. Ultrastructurally, the small rod-shaped and thin-cell-walled bacteria were observed in the parenchyma of the medulla oblongata. Listeria monocytogenes (serotype 4b) was isolated from the medulla oblongata and spinal cord. The pathogenesis of listerial encephalitis in chickens was discussed.     

冬季鸡群的饲养与管理

冬季气温比较低，气温变化无常，是慢性呼吸道疾病的多发季节。冷应激将会给鸡的饲养管理带来一定的困难。如果不能做到及时处理，轻者会造成鸡产蛋率的下降及生长受阻，重者会造成鸡只的死亡．严重影响经济效益。因此，加强寒冷季节鸡的饲养管理．提高鸡群的产蛋率，对提高养鸡经济效益至关重要。
