MAPPING THE POTENTIAL OF FOOD CROP BY-PRODUCTS AS FEED TO SUPPORT THE INCREASING OF BEEF CATTLE POPULATION IN MALANG DISTRICT
Abstrak
Malang Regency as one of regions in East Java has a large potential for the development of beef cattle
population. One of the problems faced by breeders in Malang Regency was the fluctuation of forage. Using
food crop by-products as feed becomes an alternative to meet the nutritional needs of livestock. This study
mapped the potential of rice straw, corn straw, soybean straw, peanut straw, cassava straw and sweet
potato straw as a source of feed to support the increasing of beef cattle population. The potential was
determined based on the capacity of area per district due to the production of dry matter, crude protein
and total digestible nutrients. The results showed that Donomulyo, Singosari and Kepanjen sub-districts
had the greatest potential in increasing the population of beef cattle in average by 35.814 heads per year.
Key words: beef cattle, Malang Regency, population, straw
