Weight Gain and Feed Conversion of Broiler Chickens in Reviewed from Cage Temperature and Humidity

Abstract

Background: Broiler chicken production is influenced by several factors, namely genetic, management, and environmental factors. Genetically superior chickens will not produce maximum results if not supported by a comfortable environment for chickens (comfort zone) because they are animals that will grow optimally at a certain temperature range. in addition, humidity also affects the production and health of chickens. So that the selection of the cage becomes important to create comfortable environmental conditions for chickens. Cage with a relatively stable temperature will greatly affect the production results, including body weight and feed conversion. Purpose: To determine the effect of temperature and humidity of semi-enclosed cages on weight gain and feed conversion of broiler chicken. Method: Observation was carried out during a period of maintenance of broiler chickens on farms and data collected in the form of the recording of chicken weight and feed conversion. Result: Temperature and humidity of semi-enclosed cages have a good effect on production results, with chicken harvest weight of 2197.3 grams and feed conversion of 1.52 kg. Conclusion: this study indicate that temperature and humidity have a good influence on weight gain of chickens and feed conversion value.

Lohmann Broiler Growth Performance using Positive Pressure Barn System

“…Broiler rearing in high environmental temperatures causes broilers to suffer from heat stress (Tamzil et al, 2013, Tamzil, 2014, which in turn has a negative impact on the growth and development of muscle tissue (Nawaz et al, 2021;Oktavia et al, 2021). Reduction of feed intake in broilers suffering from heat stress is an adaptive mechanism to minimize metabolic heat production, so that broilers suffering from heat stress grow more slowly compared to groups of chickens that do not suffer heat stress (Nawab et al, 2018;Kim et al, 2021).…”

“…P oultry is a homeothermic (warm-blooded) animal with body temperatures ranging from 40.5-41.5 o C (Cândido et al, 2020;Erwan et al, 2013;Erwan et al, 2014). The level of environmental temperature and relative humidity affect the performance of growth and egg production (Oktavia et al, 2021). Maintenance at high temperatures will result in poultry suffering from heat stress (Dayyani and Bakhtiari, 2013;Renata et al, 2018) as well as affecting muscle activity and tissue metabolism (Heat Production/ HP) as well as the amount of heat lost due to environmental influences (Heat Loss/HL) (Chang et al, 2018, Gicheha, 2020.…”
