These have been developed from wild ancestors by selective breeding.
Dog was the first to be domesticated used for hunting and later for tracing criminals, drug peddlers, prowlers, to lead the blinds and to draw sledges of the Eskimoes, it symbolizes topmost companion of man

Cattle Management and Feeding

India has largest number (227 million) of cattle in the world and stands 2nd in milk production. Its management includes feed, keep up (medical care) and breeding.

Except some managed farm most livestock feed by grazing on open land. Prepared feeds are of various categories:

Roughages : fodder, silage, hay and straw with high fibre content.

Concenterates : preparations of cereals, millets, forage crops with high leaf proteins, oil seeds, cakes, animal byproducts have high nutrient value.

Minerals and vitamins are also added for high yielders.

Ratio of these differs for calf, adult and the milking mothers etc.

Smoking of tobacco dried and cured leaves of plant ‘Nicotiana tobacum’ and N. rustica in the form of cigars, cigarettes, bides etc. is very toxic to the body. Smoke of tobacco contains about 300 compounds. The main compounds are nicotine, CO, HCN, polycyclic aromatic hydrocarbons, certain other stimulating products etc. Nicotine in the blood stimulates the nervous system, relax the muscles, release adrenalin hormone and increase the rate of heart beats. In pregnant ladies growth of fetus decreases and loss of weight may takes place.
Diseases Caused by Smoking : Smoking causes the following diseases.

  1. Cancer : Benzpyrene present in tobacco smoke is carcinogenic. About 95% victims of lung cancer are due to smoking.
  2. Cardio-vascular Diseases : Tobacco smoking causes increase of adrenalin secretion which increases blood pressure, heart beat rate by constricting the arteries. High blood pressure increases the chances of heart diseases.
  3. Emphysema : Tobacco smoke may break down the walls of alveoli of the lungs, decreasing the surface area for gas exchange, causing emphysema.
  4. Coughing and Bronchitis : Tobacco smoking irritates the mucous membrane of the pharynx (throat) and bronchi causing coughing and bronchitis.
  5. Pulmonary Tuberculosis : Smoking can spread bacteria of pulmonary tuberculosis from infected person to healthy persons.
  6. Gastric and Duodenal Ulcers : Smoking increases the secretion of gastric juice containing HCl. Excess of HCl causes gastric and duodenal ulcers.
  7. Effect on Immune System : Smoking reduces immunity of the body.
  8. Decrease in Oxygen carrying Capacity : Carbon monoxide of tobacco smoke rapidly binds haemoglobin of RBC and causes co-poisoning which reduces oxygen carrying capacity of haemoglobin.



Regular consumption of alcohol either in low concentration (beer, wine, etc.) or in high concentration (brandy, whisky, rum, gin, Vodka, etc.) causes dependency on alcohol which is called alcoholism. The person who has become a habitual drinker is called an alcoholic.
