EFFECT OF CAGE TEMPERATURE AND HUMIDITY ON BODY WEIGHT AND FEED CONVERSION OF BROILER CHICKENS (Pengaruh suhu dan kelembapan kandang terhadap bobot badan dan konversi ransum ayam broiler)

To improve the production performance of broiler chickens, three main factors are breeding, feeding and management. Superior seeds are obtained from the selection and cross-breeding process, with this process the resulting productivity will be maximized if supported by comfortable environmental conditions (Comfort Zone). The aim of the research was to determine the effect of using closed house cages on temperature, humidity, body weight gain and feed conversion for broiler chickens. This research was carried out from one day old to 35 days. The Day Old Chick (DOC) strain used were CP 707 with a population of 32,000 individuals. The research variables observed included temperature, humidity, body weight gain and feed conversion. Average temperature of 26.9ºC in the morning, 28.88ºC in the afternoon, 27.48ºC in the evening and an average humidity of 67.2% in the morning, 64.4% in the afternoon, 67.2% in the evening in a cage with a the closed house cage had a good effect on production results, namely chicken harvest weight of 2,196.3 grams and conversion ratio 1.50. Based on the research conducted, a cage with a Closed House system had a good influence on the increase in body weight of broiler chickens and ration conversion
