A study was conducted to investigate indications for, typical findings during, and outcome of repeat laparotomies in 57 cattle with gastrointestinal disorders. Cattle were grouped according to the reason the initial laparotomy had been performed. Group-1 cattle (n = 46) had had left or right displacement of the abomasum (LDA or RDA) or right volvulus of the abomasum. Group-2 cattle (n = 10) had had ruminal, reticular, or abomasal obstruction or perforation. Group-3 cattle (n = 7) had had obstruction, volvulus, distention, or perforation of the small or large intestine. Median interval between laparotomies was 1 month (range, 1 day to 38 months). Intraoperative findings during repeat laparotomy in group-1 cattle included LDA (n = 18), RDA (9), right volvulus of the abdomen (5), pneumoperitoneum (1), diffuse abdominal adhesions (1), cecal adhesions (1), adhesions of the rumen to the body wall (1), abscess in the cranial portion of the abdomen (1), reticular adhesions (1), localized necrosis (1), and idiopathic rumen distention (1). Intraoperative findings during repeat laparotomy in group-2 cattle included abscess in the cranial portion of the abdomen (4), no abnormalities (1), distended rumen (1), ruptured abomasum (1), recurrent abomasal impaction (1), diffuse abdominal adhesions (1), and pyloric fat necrosis (1). Intraoperative findings during repeat laparotomy in group-3 cattle included LDA (3), RDA (1), cecal volvulus (1), anastomotic rupture (1), and impacted colocolostomy (1). Seven cows and 1 calf underwent additional repeat laparotomies. Forty-four (77%) of the 57 cattle were discharged following final laparotomy. Fourteen of the 20 group-1 cattle, 1 of the 6 group-2 cattle, and 2 of the 3 group-3 cattle for which follow-up information was available were productive after repeat laparotomy.
Twenty-eight of 104 mature bulls in a herd were examined to determine the cause of scrotal enlargement. Ascites was determined as the source of a transudate that accumulated in and expanded the scrotal vaginal cavity to induce a scrotal hydrocele. In our experience, scrotal hydrocele in mature bulls usually is caused by the accumulation of fluids in the scrotal vaginal cavity without evidence of local inflammation or traumatic lesions. In the bulls reported here, ascites was associated with intestinal edema that was tentatively attributed to a hypersensitivity reaction to gastrointestinal nematodes. Ascites in mature bulls with scrotal hydrocele in which primary lesions of the scrotum and scrotal contents are not detected should induce practitioners to perform additional diagnostic procedures to determine the cause of the fluid.
Three groups of eight calves, naturally infected with gastrointestinal nematodes and artificially infected with Dictyocaulus viviparus were used to evaluate the efficacy of moxidectin pour-on at dose rates of 0.35 mg/kg and 0.5 mg/kg bodyweight. With both doses the efficacy was 100 per cent against adult D viviparus, Trichostrongylus axei, Ostertagia species and Nematodirus helvetianus. It was more than 99 per cent against Ostertagia and Nematodirus species fourth stage larvae. A small number of Cooperia species were found after treatment, and for this parasite, the efficacy of moxidectin ranged from 97.6 per cent against the larval stages to 98.8 per cent against the adults. No adverse reactions to the moxidectin treatment were observed.
