Potential of agricultural waste (rice and corn straw to development of cattle in Harau District, Lima Puluh Kota Regency

The development of livestock business requires the availability of feed, both in quantity and quality. Limited feed can cause disruption of production and reproduction of both poultry, small and large livestock.
