A Dietary Sugarcane-Derived Polyphenol Mix Reduces the Negative Effects of Cyclic Heat Exposure on Growth Performance, Blood Gas Status, and Meat Quality in Broiler Chickens

Abstract

<jats:p>Heat stress (HS) compromises growth performance and meat quality of broiler chickens by interrupting lipid and protein metabolism, resulting in increased oxidative damages. The experiment attempted to investigate whether dietary polyphenols (Polygain (POL)) could ameliorate the aforementioned adverse effects of HS on performance and meat quality. One hundred and twenty one day-old-male chicks were allocated to two temperature conditions, thermoneutral (TN) or HS, and fed with either a control diet (CON) or the CON plus four different doses of POL (2, 4, 6 and 10 g/kg). Heat stress caused respiratory alkalosis as evidenced by increased rectal temperature (p &lt; 0.001) and respiration rate (p &lt; 0.001) due to increased blood pH (p &lt; 0.001). Heat stress decreased final body weight (p = 0.061) and breast muscle water content (p = 0.013) while POL improved both (p = 0.002 and p = 0.003, respectively). Heat stress amplified muscle damages, indicated by increased thiobarbituric acid reactive substances (p &lt; 0.001) and reduced myofibril fragmentation index (p = 0.006) whereas POL improved both (p = 0.037 and p = 0.092, respectively). Heat stress impaired meat tenderness (p &lt; 0.001) while POL improved it (p = 0.003). In conclusion, HS impaired growth performance and meat quality whereas POL ameliorated these responses in a dose-dependent manner, and effects of POL were evident under both temperature conditions.</jats:p>

Potential Application of Cornelian Cherry Extract on Broiler Chickens: Growth, Expression of Antioxidant Biomarker and Glucose Transport Genes, and Oxidative Stability of Frozen Meat

“…Similarly, the body weight gain of broiler chickens improved after feeding with grape seed proanthocyanidin extract [ 46 ]. Additionally, a sugarcane-served polyphenol mix had a positive effect on the growth performance of broilers and modulated the negative effect of heat exposure [ 47 ]. Moreover, the consumption of berries, which have numerous bioactive phenolic compounds, was shown to upregulate the expression of growth-related genes such as insulin-like growth factor binding proteins [ 48 ].…”

Effects of sugar cane extract on steroidogenesis in testicular interstitial cells of male Japanese quail (Coturnix japonica)

“…The SCE food was prepared by mixing different dose of SCE powder with commercially available quail food. The dose used in present was determined based on the Shakeri et al (2020). The three groups are henceforward referred to as Control, 0.02%SCE, and 2%SCE.…”

“…Sugar cane extract (SCE) is the end product of glucose, fructose, and sucrose elimination in molasses. Over the recent years, the body of research has revealed various biological effects of sugar cane or its extract, such as its immunostimulatory, growth‐promoting, antithrombosis, anti‐inflammatory, antioxidation, modulation of acetylcholine release, and antistress activities (Akhtar et al, 2008; Amer et al, 2004; Cottrell et al, 2021; El‐Abasy et al, 2002, 2003; Khonyoung et al, 2019; Ledón et al, 2007; Shakeri et al, 2020; Takara et al, 2002). Although a number of biological effects of SCE were reported, it is still unclear whether SCE supplementation affects reproductive physiology.…”

Deleterious Effects of Heat Stress on Poultry Production: Unveiling the Benefits of Betaine and Polyphenols

“…Polyphenols have been investigated as food additives for livestock based on their important roles in oxidative stress, which have important implications for the quality of the final products [51,52]. Furthermore, as natural antioxidants, they are more acceptable by the market as they are considered safe for human health.…”
