Abstract
Livestock management includes the systems of maintenance, reproduction, and waste utilization. This study aims to examine the potential of feed sources for ruminants (cows and buffaloes) and efforts to maintain continuous feed availability associated with ruminant livestock development strategies. The data used were primary and secondary data of feed sources. Furthermore, the variables observed include cattle and buffalo population, agricultural waste production, digested dry matter (DDM), and carrying capacity. The results showed that Seruway sub-district had the highest population of cattle with 8,378 cows (4,933 ST) or 20.35% while Karang Baru sub-district had the highest population of 70 buffalo (34 ST) or 40.23%. Meanwhile, Manyak Payed sub-district produced the highest agricultural waste with 5,029.32 DDM tons/year while the low district was Kuala Simpang city. Moreover, the commodity that produces the highest agricultural waste is rice which is scattered in all districts with a total of 19,370.65 DDM tons/year. Although the cassava plant was not in all districts, it has the potential of producing 48,154.5 tons/year DDM. Furthermore, the sub-district with a great opportunity was Karang Baru which produces an unutilized potential of 2,718.23 tons/year and a carrying capacity of 2,384.41 (ST/year). This showed that Kejuruan Muda subdistrict has insufficient agricultural waste for cattle and buffalo, therefore, breeders in this sub-district get feed from the plantation and other wastes. Based on the results, Aceh Tamiang district has the potential to increase the ruminants population by utilizing forage feed from agricultural waste.
Highlights
One of the steps to reduce feed limitations is the utilization of waste as a source of feed for ruminants which minimizes costs and increases livestock populations
An effort is required to use local nuts as a source of cheap vegetable protein for humans [3] while the waste is used as ruminants feed
The application of technology in the integrated system is more emphasized to meet the needs of animal feed through processing plant waste [5] so that farmers overcome the feed availability problem by utilizing agricultural waste in the integrated system [6]
Summary
One of the steps to reduce feed limitations is the utilization of waste as a source of feed for ruminants which minimizes costs and increases livestock populations. The development effort is concerned about the availability of natural resources that increase economic growth to support people's welfare. The application of technology in the integrated system is more emphasized to meet the needs of animal feed through processing plant waste [5] so that farmers overcome the feed availability problem by utilizing agricultural waste in the integrated system [6]. This integrated system is very profitable because livestock is used as feed. The agricultural waste given to livestock is to be a mixture of different agricultural wastes [7]
