JUNIPER PUBLISHERS - OPEN ACCESS JOURNAL OF DAIRY & VETERINARY SCIENCES   Abstract Dairy animals are exposed to many toxic organic chemicals due to the increase in industrialization, heavy traffic exhaust, use of persistent organic chemicals in agriculture and incomplete combustion of wastes. Pesticides are one of the potent organic chemicals used regularly in Agriculture sector to protect the plants from insects, herbs and rodents and to increase the plant growth in all over the world. These chemicals are entered into the animal body through inhalation or using pesticides contaminated feed and water. Due to its prolonging exposure, residues of these hazardous chemicals are present in food of animal origin (milk & meat). Use of pesticides contaminated milk and meats are controlled in some advanced countries through strict legislation but its complete control and abolition is still a serious issue worldwide.

Journal of Dairy & Veterinary Sciences - Juniper Publishers   Introduction Intensive and semi-intensive dairy farms invest in automatic milking systems motivated by increased milk production per goat. Milking frequency is an important factor determining milk yield and quality of dairy goats that requires adequate feeding, welfare, health and environmental conditions [ 1 ]. The potential advantage of increased milking frequency for milk production and composition used to be main reason for applying this kind of management; nowadays, however, the production model that takes priority is one known as "low cost, high return"[ 1 ]. Since more frequent milking requires more variable costs, knowledge about the real increment of production per goat under a double milking system is necessary to decide if this practice will be adequate for each dairy system. For the twice daily milking frequency, increases in milk production of 6-...
