There are many factors that affect the energy needs of the broilers. The most important factors are: (1) Weight: body weight, fast weight gain, and more energy; on the contrary, the weight is small. Slow weight gain requires less energy. However, energy needs are calculated based on body weight. Smaller-weight chickens are larger than large-bodied chickens. (2) Egg production rate and egg production weight: High egg production and large eggs require more energy. (3) Feeding methods: Grazing rearing requires more energy than feeding, and rearing requires more energy than cage rearing. (4) Ambient temperature: After 28 days of age, the optimum growth temperature of Chai broilers is 20-25°C. If the temperature exceeds 25°C, the energy in the feed should be increased accordingly, so as to meet the insufficient energy intake caused by high intakes of temperature. When the ambient temperature is lower than 20°C, the energy concentration in the feed can be appropriately reduced. For breeder chickens, the suitable egg production temperature is 12-30 °C, the suitable growth period temperature is above 18 °C, and after 42 days, the temperature can be controlled above 21 °C; (5) Feeding purposes: The use of fat for meat as a substitute for the broiler chicken requires less energy than the firewood breeder.
