Impact of Environmental Pollution on Healthy and Productivity of Farm Animals

Abstract
Pollution may be defined as addition of undesirable material into the environment as a result of human activities. Pollution may be of the following types: air pollution, water pollution, soil pollution, thermal pollution, radiation pollution and noise pollution. The impact of different pollution as a general on healthy of farm animals are cancer, neurobehavioral disorders, cardiovascular problems, reduced energy levels, premature death, asthma, asthma exacerbations, headaches and dizziness, irritation of eyes, nose, mouth and throat, reduced lung functioning, respiratory symptoms, respiratory disease, disruption of endocrine and reproductive and immune systems. Exposure to environmental pollutants affected reproductive functions and in particular, produced adverse effects on pregnancy outcomes, fertility, and fetal health. Exposures to ambient levels of pollutants are associated with low birth weight, intrauterine growth retardation, prematurity, neonatal death, and decreased fertility and decrease of sperm quality in males and indicated also that female fertility was also disturbed. The most common disorder of male fertility is the insufficient production of normal sperm, with good mobility in the somniferous tubules. Polluted drinking water by chemicals produced waterborne diseases like, typhoid, liver and kidney damage. In this paper the effects of various environmental factors on healthy, function of animal, fertility and reproductive efficiency are reported.
