Client communication is the key to success in practice as it is an important skill to narrow down the gap between owner of the animal and the veterinarian. In other words, it is a meaningful exchange of information between attending veterinarian and the owner of the ailing animal for improving health care outcome. In client centered world (where client satisfaction is in the core of practice), communication with client  has assumed greater significance whether it is related to educating him about preventive health care; explaining about disease diagnosis, prognosis and treatment options; or explaining about chronic disease condition and its outcome. Communication also influences the wellbeing of the patient. Therefore, development of trust in client-veterinarian relationship is crucial as it not only enhances the quality of history taking but also help in better clinical diagnosis and subsequent clinical care. Importance of Communication •     Client experience and feedback is important for providing good clinical

History and History Taking History in medical/ veterinary terminology is a record of information about the health, illness (past and present), diet, feeding, management,preventive health schedules (vaccination,deworming, dipping, sprays) and hygiene etc. History taking and physical examination is the important step in making a correct diagnosis as it provides valuable information to determine the cause of clinical manifestations. The main purpose of taking history is to get detailed information about the animal, its activities, behavior, diet, health care practices, nutritional status, housing, development of abnormal signs and treatment given, if any. The animal may be cared by owner himself or by an attendant. In the event of animal care given by an attendant, information obtained from the attendant may not be complete and fully reliable as sometimes attendant may not provide correct events and complete picture to hide his mistakes. For obtaining right information a good rapport is to be made with the owner or the attendant. A complete history not only suggest diagnostic possibilities but can also suggest diagnostic probabilities. For example a calf or heifer is unlikely to have Johne’s disease or an adult cow is more likely to suffer from parturient paresis than a first calf heifer. History can also provide a lead for further examination or which system is to be paid special attention.

Small ruminants are grazing mammals and this group consists of sheep (Ovis aries) and goats (Capra hircus).Advantage of these animals is their low cost, small size and marginal land use, which convert into high quality animal products. Sheep is a grazing animal and goat is a browsing animal. They are generally kept in flock. Therefore flock management is more important than the individual animal. Though, procedure of history taking and physical examination is almost similar to other animals, some peculiarities warrant a separate discussion. Sheep The general methods of history taking and physical examination of sheep are similar to cattle and goat starting from owner’s complaint (history), signalment of the patient, history of the ailing

In pigs, making a diagnosis of disease is no way different from that of other species. It is based on assessing the owner’s complaint, history of the farm and the ailing pig, signalment factors, detailed observations of the ailing pig, the other pigs in the group and their environment, detailed physical examination. These observation may lead to a provisional diagnosis. Further clinical tests, clinical pathology and a post-mortem examination of the dead pigs are to be taken up to confirm or refute the provisional diagnosis. Because pigs are kept in groups and owing to infectious nature of many diseases, the health of other pigs in the group should also be taken into account. History and General Examination General examination of swine is conducted without handling them. The physical examination of swine includes history taking, examination of environment, examination of group of swine, post mortem examination

History and thorough physical examination is crucial procedures in making diagnosis in horses. Mental attitude of a horse may help in understanding whether it has a localized problem or is systemically ill. Horse is better approached by its left side, keeping himself/herself next to the shoulder. Examination of the horse should be started in a non-threatening, easy, and quiet way. Generally physical examination starts at the head to prevent possible injury to unfamiliar examiner. Abnormalities in demeanor and mentation can be assessed by watching the horse’s initial response to the environment. The locomotor and neurologic systems are examined by observing the horse’s movements and gait at walk and trot, both on straight line and in turns, and backing. Horse weight should be taken. General inspection of the horse should be conducted by standing back keeping a safe distance and looking at the horse for it condition, abdominal shape, muscle symmetry,

Making a correct and an early diagnosis is very much important for undertaking rational and effective treatment for fast recovery, avoiding unnecessary medication, reducing the load of so many drugs on body metabolism, reducing environmental pollution and the cost of treatment. There are four important pillars for making a correct diagnosis viz. the history, the systematic clinical examination, the correct clinical diagnostic techniques and the laboratory support. History Taking Clinician’s first step in making a diagnosis is through asking the owner’s complaint. Accurate and complete history may be obtained from focusing on the details of the patient (name, number, species, breed, age, sex and weight), vaccination status, deworming schedule, nutritional history, past and present medical history and environmental history.

Medication refers to administration of drugs. The route, dose and frequency of the drugs administration is most important in providing health care and welfare of the animals. Wide range of body size and their weight in animals and rearing practice makes the treatment and drug administration strategies a bit complex. Because of this complexity wide range of drug formulary and drug delivery strategies has been developed in animals for health care. Route of drug administration varies from oral administration, parenteral administration to local application on skin and mucus membrane. Similarly forms of the drugs varies from liquids, semisolids to solids for oral administration; from clear solution, suspension, emulsion to powder for parenteral administration; and from powder, cream, paste, suspension, ointment, solutions to emulsifiable concentrates for local application. Oral Administration of Drugs All three forms of drugs viz. liquids (solution, emulsion, suspension), semisolids (paste), and solids

Ruminant Ruminant's gastrointestinal tract is unique and different from equines, canines and felines because of complex stomach (polygastric) compartmentalized as rumen, reticulum, omasum and abomasum leading to a different digestive process as well as their diseases. In gastrointestinal dysfunction of ruminant, a complete examination, starting from history, systemic states, visual inspection of abdomen, examination of buccal cavity and esophagus, examination of left and right abdomen, per rectal examination, radiographic examination, paracentesis abdominis to laparoscopy is recommended. History •     A detail history, with respect to status of pregnancy, lactation, dietary nature (grazing, stall fed), diet

Liver is one of the largest and most sensitive organ in the body performing important role in digestion and metabolism; regulation of nutrient; and production of proteins, enzymes, hormones, clotting and immunological factors. Liver also plays significant role in detoxification. Liver is affected in both primary and secondary liver diseases. Clinical signs of the hepatic dysfunction appears only after a large portion of the liver (about 75%) is inactive because liver has a large reserve of function. Therefore, a systematic clinico-pathological examination of the liver becomes mandatory to identify liver abnormalities. Clinical Signs of The Liver and Biliary Disease Jaundice (pre hepatic, hepatic, post hepatic or extra hepatic), nervous signs (hyperexcitability, convulsions, coma, weakness, muscle tremors, dullness, compulsive walking head pressing, mania),

Farm Animals and Horses Urinary system mainly comprises of kidneys, ureters, bladder and urethra. In farm animals, diseases of urinary bladder and urethra are diagnosed with more frequency than that of kidneys. Renal insufficiency is observed as a sequel in cases of nephritis (pyelo or embolic nephritis), nephrosis or amyloidosis. Urinary diseases are clinically manifested with pain, dysuria, and variation in urine flow (polyuria, oliguria to anuria) and changes in urine (proteinuria, hematuria, hemoglobinuria, myoglobinuria, glycosuria, ketonuria, crystalluria, pyuria, and cellular casts). Decreased body weight, loss of appetite, polyuria, polydipsia and ventral edema are seen in chronic renal failure. Like dogs and cats, urinary tract is not accessible in large farm animals for clinical examination. Trans abdominal palpation of kidneys is feasible in calves and small ruminants. Rectal palpation, urine examination and renal function tests provide diagnostic assistance in the diseases of urinary tract in large animals. Clinical Manifestations Dysuria and abdominal pain are generally seen in urinary tract disease. Acute pain from urinary tract disease is not common.
