The dairy cow normally has her first calf at the age of two when she will be producing around 35 litres of milk a day. In subsequent lactations this figure rises even higher. She will continue to be milked for 10 months - but will be made pregnant again in the third month. Professor John Webster, Department of Animal Husbandry, Bristol University says: "The dairy cow is the hardest working of all our farm animals and it can be scientifically calculated. It is equivalent to a jogger who goes out for six to eight hours a day which is a lunatic pursuit. He states that almost 100 per cent of cows suffer from laminitis - a disease which causes 'great pain to the cow' (MAFF). Tissue lining of the foot becomes inflamed and may lead to ulcers. <br /><br />NO COPYRIGHT INFRINGEMENT INTENDED. FOR EDUCATIONAL PURPOSE ONLY.
