Syllabus

2. Animal Physiology

2.1 Physiology of blood and its circulation, respiration; excretion.

  • Endocrine glands in health and disease.

2.2 Blood constituents – Properties and functions-blood cell formation

  • Haemoglobin synthesis and chemistry, plasma proteins production, classification and properties, coagulation of blood;
  • Haemorrhagic disorders-anticoagulants-blood groups-Blood volume
  • Plasma expanders-Buffer systems in blood.
  • Biochemical tests and their significance in disease diagnosis.

2.3 Circulation – Physiology of heart, cardiac cycle, heart sounds, heartbeat, electrocardiograms.

  • Work and efficiency of heart
  • effect of ions on heart function
  • metabolism of cardiac muscle, nervous and chemical regulation of heart, effect of temperature and stress on heart, blood pressure and hypertension, osmotic regulation, arterial pulse, vasomotor regulation of circulation, shock.
  • Coronary and pulmonary circulation, Blood-Brain barrier- Cerebrospinal fluid- circulation in birds.

2.4 Respiration – Mechanism of respiration,

  • Transport and exchange of gases -neural control of respiration-chemoreceptors-hypoxia-respiration in birds.

2.5 Excretion-Structure and function of kidney-formation of urine-methods of studying renal function

  • Renal regulation of acid-base balance:
  • physiological constituents of urine-renal failure-passive venous congestion
  • Urinary secretion in chicken-Sweat glands and their function.
  • Bio-chemical test for urinary dysfunction.

2.6 Endocrine glands – Functional disorders their symptoms and diagnosis.

  • Synthesis of hormones, mechanism and control of secretion
  • hormonal receptors classification and function.

2.7 Growth and Animal Production

  • Prenatal and postnatal growth, maturation, growth curves,
  • measures of growth, factors affecting growth, conformation, body composition, meat quality.

2.8 Physiology of Milk Production, Reproduction and Digestion-

  • Current status of hormonal control of mammary development, milk secretion and milk ejection,
  • Male and Female reproductive organs, their components and functions.
  • Digestive organs and their functions.

2.9 Environmental Physiology

  • Physiological relations and their regulation; mechanisms of adaptation,
  • environmental factors and regulatory mechanisms involved in animal behaviour, climatology – various parameters and their importance.
  • Animal ecology.
  • Physiology of behaviour. Effect of stress on health and production.
