Abstract: The low availability and quality of forage for livestock during the dry season is the main problem faced by the farmers in Indonesia. To alleviate the problems, the use of agricultural by-products that their nutritive value has been improved like ammoniated straw as animal feed is recommended. However, most farmers have poor understanding about ammonisation of straw technology. For this reason, an extension on ammonisation of straw technology was introduced to the farmers. However, after teaching on the ammonisation technology, practice of making ammoniated straw and demonstration on the superiority of using ammoniated rice straw as animal feed had been introduced to the farmers, only one of 20 farmers followed the training who adopted the technology. It is suggested that the purpose of raising the cattle is the main factor determining adoptability of the technology by the farmers.
