Abstract

WINA S. NABABAN: The Study of Agriculture by Product Potency as Feed Resources for Cattle in Subdistrict Dolok Masihul, Regency Serdang Bedagai. Under the supervision of TRI HESTI WAHYUNI and ADE TRISNA. The land use change and climate limit the availability of forage, which is the principal feed ruminants. Optimization of the utilization of agricultural by product and agro-industries can improve the availability of feed. Integration with the business of agriculture is an alternative for sustainable livestock development. This study analyzes the potential of agricultural by product as ruminant feed in the District Dolok Masihul Serdang Bedagai. The parameters were the production of fresh, dry matter (DM), crude protein (CP) and total digestible nutrients (TDN) of agricultural by product, carrying capacity of agricultural by product in animal unit (AU) and carrying capacity index of agricultural by product. The results showed the amount of fresh production based on agricultural by product material fresh, dry matter, crude protein and TDN such as 176 700 tonnes; 62.148,030 tons, 16.686,827 tons and 36.861,537 tons respectively with a carrying capacity of agricultural by product as a source of feed is 13.832 AU, 16.129 AU, 69.240 AU and 21.954 AU respectively. Carrying capacity of the waste based on the index of food crops in the district Dolok Masihul, supply is still insufficient. So the district could potentially add Dolok Masihul cattle based on fresh, BK, PK and TDN as 7.279 AU, 8.893AU, 43.844 AU and 13.792 AU to optimize the potential of agricultural by product.
