Comparative study of broiler chicken performance in closed house and conventional system in North Sumatera

The influence of a comfortable environment provides good performance results on the quality of chicken meat for sustainability to improve the health quality of broiler chickens. This research was conducted from July 2021 to September 2021 in Deli Serdang, Serdang Bedagai and Simalungun districts. This research aims to look at the effects of maintaining closed house and conventional systems. The parameters observed are temperature, humidity, FCR, depletion, Performance Index. As primary data was conducted direct observation to the cage closed house JS population 30,000 tails and conventional cage RS population 4500 tails and interviewed as many as 104 samples (31 respondents closed house, 73 respondents conventional)with the sample method intentionally (purposive sample) and uses the formula Slovin. The appropriate temperature and humidity influence will result in a good performance of broiler chickens. Temperature and humidity detection using the HTC-2 thermohydrometer tool. Data processing results with statistical tests describe FCR results at closed house 1,516 and conventional 1,554; depletion closed house 3% and conventional 4.14% and IP on closed house389 and conventional 358.
