Abomasal Tympany

• RISK FACTORS

NO offering of water to calves

Poor milk hygiene/ intermittent feeding of

large volumes of milk/cool milk temperature

Dietary changes

Abomasal bezoar

Page 3: Calf bloat /abomasal tympany by Dr.Amandeep

Risk Factors

Organisms like C.perfringens , Campylobacter,

Sarcinia

Compromised immunity from inadequate colostrum

Ingestion of foreign bodies

Vitamin / mineral deficiency

PATHOPHYSIOLOGY

Large

quantity of

milk replacer

at infrequent

intervals

Proliferation

of

lactobacilli ,

E.coli,

C.perfringen

s

Fermentatio

n of sugars

produces

CO2

Clinical Signs• Colic

• Refusal to drink milk

• Restlessness & Depression

• Succusion of distended abdomen produces

splashing & metallic sounds

• Passage of stomach tube fails to relieve

distension

• Reduced fecal output & occasionally melena

• Metabolic alkalosis followed by metabolic acidosis

Page 6: Calf bloat /abomasal tympany by Dr.Amandeep

Treatment

• Prevent further suckling

• Don’t tube the calf

• Paracentesis- through right flank

• Right flank lapratomy

Page 7: Calf bloat /abomasal tympany by Dr.Amandeep

Treatment

• I/V fluids- correct dehydration electrolyte &

metabolic derangement

• Earlier antibiotic Rx sometimes effective

• Addition of 0.1% formalin(37%

formaldehyde) to milk replacer reduces

incidence

Recent Developments

• Length of tube to reach the stomach is typically

length from mouth to last rib on calf’s side

• After insertion, lift front end of calf up so that

calf is sitting/standing in near vertical plane

• Procaine penicillin (10 cc of 10,000 IU/ml

solution) mixed in 2 cups of mineral oil should

be administered into the tube,

Page 9: Calf bloat /abomasal tympany by Dr.Amandeep

Recent Developments

• With a cup or two of warm water as a “chaser” to

push the medication out of the tube and into the

stomach

• Subcutaneous administration of procaine

penicillin (4 cc of 10,000 IU/ml solution per 100

lbs of bodyweight, 1-2 times per day)

• Injection of 50-100 mg of intravenous or

subcutaneous flunixin meglumine

Continue....

• ScourGuard from Pfizer

• Scour Bos 9 from Novartis

• These products contain toxoid against C.

perfringens & are designed to be given to

pregnant cow prior to calving

Management

• Monitor protein, energy, vitamin, and trace mineral

• Adequate colostral intake by newborn calves is must

• Monitor changes in the volume of milk ingested by a

hungry calf

Page 12: Calf bloat /abomasal tympany by Dr.Amandeep

Management

• Prolonged interruption of suckling must be made

time-efficient in order to limit engorgement of the

udder and subsequent ingestion by the neonate of

a larger than normal milk meal

• Sudden and severe changes in weather may cause

dams and their offspring to seek shelter or remain

recumbent for prolonged periods of time

Ruminal bloat

Page 14: Calf bloat /abomasal tympany by Dr.Amandeep

Risk factors

• Rumen putrefaction

• Obstruction of cardia or

esophagus

• Vagal indigestion

Page 15: Calf bloat /abomasal tympany by Dr.Amandeep

Pathophysiology

Large quantities of milk

by escaping

esophageal groove

Putrefactive

decomposition by

proteolytic bacteria

Aerobic population

converts into anaerobic

Page 16: Calf bloat /abomasal tympany by Dr.Amandeep

Clinical signs

• Diarrhoea

• Poor development

• Rough hair coat

• Recurrent bloat

• Complication of severe bronchopneumonia

Page 17: Calf bloat /abomasal tympany by Dr.Amandeep

Management

• Reduction in the volume of milk fed per feeding

• Feeding from nipple rather than bucket

• Introduce calf starter to promote rumen

development

• Course of oral antibiotics(500 mg oxytetracycline)

o.d help in killing of putrefactive gut flora

• Placemant of fistula( buff’s screw trocar)
