       Singapore (新加坡) is a small island with a busy city, factories and a large port (港口). Nearly

all of the food is from abroad because the island is so small and it has very few farms. Hay Dairies is

the only goat farm on the island. 

       Goats are useful animals. They are able to produce milk for us to drink. The milk can also be

used to make many things including cheese, soap and beauty creams. Their meat can be eaten and

their hair can be made into beautiful clothes. Their skin can be made into leather. In some parts of

the world, goats are kept to carry heavy loads (重物). 

      The, 1,000 goats at Hay Dairies are kept for their milk. The farm was set up by John Hay, a pig

farmer who saw that there was a growing need in Singapore for goat's milk. One in five children in

Singapore suffers (患病) from Asthma (气喘), a disease which does a lot of harm to the breathing

pathway and leads to a sudden difficulty in breathing that can cause death if not treated quickly. Many

of these children cannot drink cow's milk as this can start an asthma attack and doctors believe goat's

milk is healthy choice.
