Abstract: Egg production, infrared thermography, natural diet supplement.Submitted: September/2014 Approved: March/2015 ABSTRACT Laying hens reared under tropical conditions are usually under heat stress. Propolis is known for its pharmaceutical properties, such as increasing cell tolerance to hyperthermia, because of its antioxidants effects. This study aimed at evaluating the influence of different dietary propolis inclusion levels on the performance, egg quality, and bird surface temperature of layers. In this exp… Show more

“…Additionally, Seven, Seven, Yilmaz, and Simsek () found a significant useful effect of beehive products on egg weight at a recommended dose of 2 and 5 g of ethanol extract of propolis/kg of feed. However, other researchers reported non‐significant effects of propolis supplementation on egg production and quality traits (Arpášová et al., ; Belloni, Almeida Paz, Naeaes, & Productive, ; Ting, Yeh, & Lien, ). The RJ‐treated birds in the current work exhibited an improved eggshell ratio and thickness.…”

“…On the other hand, Al-Daraji et al (2012) reported that the chicks from eggs injected with L-arginine presented higher weight gains than control groups. Researchers (Biavatti et al, 2003;Ziaran et al, 2005;Acikgoz et al, 2005;Canogullari et al, 2009) observed that the addition of propolis to broiler diets did not significantly influence broiler body weight and body weight gain, or the performance of laying hens (Belloni et al, 2015). In the current study, the amount of propolis biological material may have been insufficient to promote positive broiler performance because, according to Biavatti et al (2003), the effects of propolis on broilers body weight and body weight gain are observed only after 14 days of age, depending on the level of concentrate.…”

“…In agreement with our result in the current study, Arpasova et al (2016) and Tatli reported that VitC or propolis had no effect on yolk index. Belloni et al (2015) concluded that propolis supplementation to laying hen diets had no significant effect on egg specific gravity. Abdel-Kareem and El-Sheikh (2017) reported that propolis supplementation to the layer diets (250, 500 and 1000 mg) did not influence EW.…”

“…Antibiotics, used in poultry diets to improve production performance, have been prohibited because of their negative subsequences in birds and human health (Zulkifli et al 2000;Casewell et al 2003;Apata 2009). Stressors (regardless of their sources) have a highly detrimental influence on laying hens (Puthpongsiriporn et al 2001;Belloni et al 2015), which depresses feed intake (FI), body weight, egg production (EP) and egg quality (Puthpongsiriporn et al 2001(. Bee glue or propolis, which contains wax (30%), resin (50%), essential oils (10%), pollen (5%) and some other substances (Kumova et al 2002;Arpasova et al 2016) and looks an adhesive, dark yellow to brown coloured balsam, is one of the products from beekeeping which is found in the hives (Galal et al 2008); since bees collect propolis from various origins, namely buds, leaves and similar parts of trees and other plants such as pine, oak, eucalyptus, poplar and chestnut (Valle 2000;Seven et al 2010) its composition differs depending on a wide variety of factors including collecting location, time and plant source.…”
