Considering temperature - humidity of house and defining mixturefeeddiet suitable for backyard chickensperiod from 1 to 18 day - age at Tra Vinh
This study was carried out from 28th October 2019 to 2nd January 2020 at experimental farm in veterinary husbandry of Tra Vinh University. Experience analyzed temperature zone for young chicken fed mix diet, there by evaluting effect of brooding floor and special rising spots temperature to growth performance as feed use of efficiency of chicken period 1 to 18 day - age. Processing research in showing temperature zone suitable for chicken from 25.4°C to 31.2°C with relative humidity of air middle as well as 65.79% of experimental period. Cloaca temperature change by day age, sex of chicken and time zone daily, index estimated from 39.32°C đến 40.77°C at those spots. Experiment was designed by completely randomized method consist of fourth treatments, every treatment repeated three times so total of young chickens which was assessed in growth rate and ability of feed conversion have 240 chickens. Most of livestock technical parameters show stable result under season convert climate condition. So that chicken herd growth well and illless through star phase. Body weight of chicken at 18 day - age from 172.8g to 185.0g/chick. The feed transferring was better with FCR achieve value ofmid range from 1.95kg to 2.16kg for all treaments and relatively suite of life with local condition and character of breeds.
