A 1-month-old female llama was examined because of signs of acute abdominal pain. Physical and ultrasonographic examination revealed a cylindrical mass in the left caudal quadrant of the abdomen. Results of serum biochemical analyses and CBC were within reference ranges. Exploratory laparotomy revealed an ileocecocolic intussusception. Ileocecal resection and end-to-end ileocolic anastomosis were performed. After surgery, fecal examination revealed many coccidial oocysts, although a direct association between coccidiosis and intussusception could not be determined. The cria recovered without serious complications.

Postmortem examination of a 3-year-old male Iranian native sheep with a history of anorexia and severe colic, revealed an intussusception of the small intestine, 30 cm proximal to the ileocaecal junction. Scattered hyperplastic lesions were present in the jejunal and ileal mucosa especially in intussuscipien. Microscopic examination of these lesions showed severe papillary hyperplasia of the epithelium associated with developmental stages of coccidia in the epithelial cells. An unusual type of intussusception and the presence of the proliferative nodular form of coccidiosis in the intestinal wall of intussuscipien suggested that coccidiosis could be considered as the possible cause of the problem.

Three out of 12,974 fowl in 13 floor pen tests spanning 7 years developed intestinal intussusceptions. Multiple (two separate) intussusceptions in the same bird and a single intussusception with prolapsed colon are conditions both reported for the second time only. One of the three birds had coccidiosis and two had coccidiasis. It is suggested on the basis of these and previously published data that the coccidiosis or coccidiasis sometimes associated with intussusceptions might develop secondarily following reduction of intake of food and, therefore, of anticoccidial agent, caused by the latter condition. Intussusception is probably not caused by starvation per se, since it is rarely associated with poultry diseases which cause primary anorexia. The morphology of the fowl's intestine probably makes invagination physically difficult and induction of an intussusception probably stems from an area of induration, exacerbated by any of several inconsistent predisposing factors. Probably no single cause of intestinal intussusception is identifiable.

In a flock of 1017 pullets aged 7 weeks feeding was reduced from 2 to 0.5 bags a day due to feed scarcity. The pullets became weak and some died 5 days later. Necropsy showed duodenal coccidiosis, often an empty gastro-intestinal tract and intussusception of the ileum near the ileocaecal junction. The tips of the caecae and/or their mesentery were often telescoped into the ileum. Affected areas were inflamed, necrotic and often gangrenous and sloughing. On another farm with 328 pullets of 12-weeks-old intussusception of the ileum near the ileocaecal junction was again observed when feeding was reduced from two bags in 3 days to 1 in 5 days. The caecae and/or their mesentery were also involved. Examinations for coccidiosis gave negative results. These observations indicate that starvation may cause intestinal intussusception in fowls.

In a large population of animals, it is normal to have some die each day from causes not related to disease, which is often referred to as natural causes. In poultry production, this phenomenon is commonly referred to as daily mortality. In egg-producing chickens, many of the natural causes of death are associated with making an egg. The causes of normal mortality in commercial egg-laying chicken flocks have been described very little to date. A commercial chicken egg farm, housing approximately two million single-comb white leghorn chickens (Gallus gallus domesticus) in 16 egg-producing flocks, was visited on a monthly basis to monitor bird health, body conditioning, skeletal integrity, and causes of daily mortality in an attempt to provide early detection of health abnormalities. A representative sample of daily mortality from each flock was necropsied to determine the cause of death. Reported herein is a summary of visits for a period of 38 mo from June 2011 to July 2014. The top 15 causes of normal mortality, in rank order of prevalence, were determined to be the following: egg yolk peritonitis, hypocalcemia, gout, self-induced molt, salpingitis, caught by spur, intussusception or volvulus (twisted intestine), cannibalism (pick out), tracheal plug, septicemia, fatty liver syndrome, internal layer, layer hepatitis, persecution, and prolapsed vent. Other causes noted were hyperthermia (during summer), trauma, coccidiosis, ovarian neoplasia, being egg bound, urolithiasis, peritonitis (not egg yolk induced), leg fracture, caught in the structure, tumor (other than ovarian origin), wing fracture, exsanguination, and cardiomyopathy.
