In August 2016, training on (semi)close house management for broiler farm managers of different farms in West Java was organized by Mr Rajali Yahya on behalf of DIFS-live. The training, given by Wageningen-UR expert Dr. Rick van Emous, focused on the different aspects of broiler farm management in (semi)closed houses such as a comfortable climate, effective temperature, litter and equipment (water, feed, light).

Broiler production under tropical circumstances is a challenging task as the broilers face high ambient temperatures which can have a devastating effect. When these high temperatures are combined with high humidity levels, heat stress can occur causing an even more harmful impact. Heat stress occurs in a situation where the sum of the temperature and the relative humidity level exceeds 100 for more than 5 hours. Prevention of heat stress in open houses is possible, however the effect is limited. Therefore a transition from open to (semi)closed houses for broilers is proposed in order to achieve improved and sustainable broiler production in Indonesia.

It is estimated that broiler farmers who change from an open house to a (semi)closed house, can improve their gross margin with 25 to 30% on average. This is caused by a 15% lower feed conversion rate, a 30% higher daily bodyweight growth rate, a 70% lower mortality rate and by a doubled stocking density. Besides the above stated positive effects on production performance, it is also suggested that the use of antibiotics can be reduced as a result of the transition.

More knowledge on how to manage a (semi)closed broiler house is however necessary to optimize the potential of these systems. Therefore, a training session was organized on the 8th and 10th of August for the interested pilot farms within the project. The training took place in Bogor and Bekasi and in total 35 broiler farm managers participated.
