i recently bought seven hampshire barrows to raise (40 pounders). two days after they were delivered one of them had a white puss like film over his eyes and was sluggish. when he would get up to walk he would stagger from side to side. i saw him drink and eat only once. i gave him a round of antibotics (tylan). this morning, a week after delevery i found him dead. also today i noticed another one starting to exibit the some of the same symptoms. tomorrow i think i will seperate him from the herd. does anyone know what my problem is and is there anything i can do to prevent the others from being infected?
