The demonstration of the use and measuring of the effects of improved concentrate feed on the performance of the dairy cows on nine demo farms in each of the coops KPSP Saluyu Kuningan and KPGS Cikajang Garut started in November. Compared with the standard concentrate feed produced by the coops, the improved concentrate feed is composed of a lower number of ingredients of a more stable quality while also a commercial mineral/vitamin premix of Trouw Nutrition Indonesia is added. The improved concentrate feed has a higher protein content and better mineral content. On the demo farms, milk production and amounts of feed given per cow etc are measured on a daily basis.
