Abstract: The meta-analysis data were obtained from a survey of published articles over 15 years. The data were selected to classify the factors that impact broiler production and separated by influence aspects of animal production (thermal environment and other factors). The relevant data for each study were systematized, grouped and later tabulated and inserted into a database prepared in a spreadsheet. The variables used to analyze the thermal environment were temperature (comfort, high and low) and performance data … Show more

“…Heat stress is a challenge in tropical countries such as Brazil. Broilers exposed to heat stress impact performance (Zhou &Yamamoto, 1997;Quinteiro-Filho et al, 2012;Baracho et al, 2019) and decrease the relative weight of the lymphoid organs (Niu et al, 2009;Quinteiro-Filho et al, 2012). Usually, a controlled environment system is used by farmers to mitigate heat stress (Zhao et al, 2013).…”

“…The slaughter weight of broiler chickens was different elevation areas due to different temperatures, humidity, and precipitation, which the chickens' welfare. According to Baracho et al (2018) [6] and Baracho et al (2019) [7] , broiler welfare's contributing factors include temperature, humidity, and livestock. High environmental temperature is one of the challenges to the optimum performance of broiler chickens.…”

“…Annually, over ten billions of poultry meat are globally produced (Mench, 2018). However, some factors namely; poor poultry production as a result of diseases, poor ventilation and inadequate floor space (Baracho et al, 2019) are inhibiting the growth of the poultry meat industry in the humid tropical climate such as Nigeria.…”

“…Other factors that had been shown to influence poultry production include genetic strain, climatic conditions (Baracho et al, 2019), stocking density (Jones, et al, 2005), price of feed (Adebayo & Adeola, 2005), diet, veterinary care (Cernicchiaro et al, 2016), and environmental enrichment (Riber, et al, 2018).…”
