Anastomoses of intestinal tract as a sequela to rectal stricture in swine.

Rectal stricture with anastomoses of colon and/or small intestine to a spherical dilatation of the descending colon proximal to the stricture was observed in six swine. In three of these swine, feces bypassed most of the colon in passage from the small intestine to the dilated colon. Rectal stricture with an anastomosis of a loop of colon to the rectal stricture was observed in one pig where feces bypassed much of the stricture.     

Rectal prolapse.

Rectal prolapse is a common occurrence in cattle and small ruminants. This article discusses the causes, correction, and postoperative treatment of rectal prolapse in cattle and sheep.     

猪流感和猪感冒的区别与防治

一、猪流感和猪感冒的区别1、猪流感。猪流行性感冒是由猪流感病毒引起的一种呼吸道传染病。临床特征为突然发病,迅速蔓延全群。该病毒主要存在于病猪的呼吸道分泌物中,排出后污染环境、饲饮用具等,病猪、飞沫、空气、老鼠、蚊蝇等都是此病的传播途径。猪流行性感冒发生之初,病     

Anaesthesia of swine

Extract

The pig is a difficult animal to anaesthetize under practice conditions. The introduction in the last 5–6 years of several potent, effective drugs has made porcine anaesthesia more practicable. Although the ideal agent has yet to be found, many of the newer agents provide relatively simple, safe and effective chemical restraint of the pig.     

Passive protection of segmented swine colonic loops against swine dysentery

Swine-ligated loops were used to demonstrate passive protection against swine dysentery. Loops inoculated with immune sera containing complement and with homologous Treponema hyodysenteriae were normal at necropsy. Loops inoculated with heat-inactivated immune sera and heterologous T hyodysenteriae were not protected. Loops inoculated with heat-inactivated immune sera and homologous T hyodysenteriae were partially protected. Positive control loops inoculated with isolate B204 (88%) or B234 (44%) T hyodysenteriae and normal sera developed lesions typical of swine dysentery, whereas negative control loops inoculated with nonexposed sera only were normal.     

猪传染性胸膜炎与猪瘟混合感染的检疫

近年来,猪瘟的发病率呈上升趋势,病猪临床症状表现为多样化,主要以非典型猪瘟为主.患有非典型猪瘟的病猪不易被发现,易在猪群中散播病毒,使猪体抗病力降低,极易并发其他细菌感染,造成大批死亡.猪传染性胸膜肺炎是由胸膜炎放线杆菌引起猪的一种呼吸道传染病,以呈现胸膜炎症状和病变为特征.当猪瘟与猪传染性胸膜炎混合感染时,猪的发病率、死亡率均很高.
