IMPACT OF GRAZING ON THE QUANTITY OF MILK BY THE COWS B.RAVICHANDRANE, TGT TKRSP GHSS, KORAVELIMEDU, PUDUCHERRY-607402 INTRODUCTION: Milk is the most important nutrient not only for the Children but also for the elders. It becomes an important part of our diet. Milk is a great source of calcium, which is essential for healthy bones. It contains protein, which helps to rebuild muscles. Nowadays milk and milk products are very much used in towns as well as in villages. Moreover milk production becomes one of the major occupations in villages. The effect of feeding habit plays a major role in the milk production and the health of the cows. Nowadays most of the cows are grown in homes while less number is sent for grazing. AIM: * To prove that cows which are sent for grazing produce more milk METHODOLOG Usually grazing cows looks more healthier and also gives more milk than the home feeding cows. To prove our hypothesis we selected the village Koravelimedu which is nearby our school and done a survey with 60 cows with due permission from their owners. We selected 30 cows each with similar variety, age group, locality, environment etc., with different feeding habits i.e., Grazing and Home feeding. We observed these 2 groups of cows for a period of 9 weeks. We have accounted the quantity of milk they produced both in the morning and in the evening in terms of litres. Finally we came to the following conclusions. Sl.No. | Week | Milk Production in Litres | | | 30 Grazing cows | 30 home feeding cows | 1 | I | 1197 | 1176 | 2 | II | 1186 | 1197 | 3 | III | 1238 | 1186 | 4 | IV | 1228 | 1188 | 5 | V | 1249 | 1218 | 6 | VI | 1240 | 1219 | 7 | VII | 1206 | 1179 | 8 | VIII | 1218 | 1175 | 9 | IX | 1227 | 1120 | Total | 10989 | 10658
