Dietary Supplementation of Some Antioxidants as Attenuators of Heat Stress on Chicken Meat Characteristics

Abstract

The study evaluated the effect of dietary chromium and vitamin C, Zinc, and sorrel wood powder supplements on chicken health and the nutritional, textural, and sensorial quality of chicken meat. A total of 120 Cobb 500 chickens (heat stress, 32 °C) were assigned into four treatments: control diet (C) and three test diets including 200 µg/kg diet chromium picolinate and supplemented with: 0.25 g vitamin C(VC)/kg diet (E1), 0.025 g Zn/kg diet (E2), and 10 g creeping wood sorrel powder (CWS)/kg diet (E3). Crude protein concentration increased in the breast meat from the E3 group; crude fat decreased in E1 and E3 compared to those fed the C diet. Dietary combinations of CrPic with VC, Zn, and CWS increased redness and decreased the luminosity parameter of breast meat compared with the C group. Dietary combinations of CrPic with VC and CWS lowered the hardness of breast meat. Significant positive correlation was found between hardness–gumminess (r = 0.891), gumminess–cohesiveness (r = 0.771), cohesiveness–resilience-EE (r = 0.861; r = 0.585), ash-L* (r = 0.426), and a negative one between ash–a* (r = 0.446). In conclusion, a dietary combination of CrPic with VC, Zn, and CWS as antioxidant sources could have a beneficial effect on quality without affecting sensory attributes.

Effects of Supplementing Sea Buckthorn Leaves (Hippophae rhamnoides L.) and Chromium (III) in Broiler Diet on the Nutritional Quality and Lipid Oxidative Stability of Meat

“…The analysis of proximate composition (dry matter, crude protein, ether extract, and ash) of plant and meat samples (breast and thigh) was determined according to [ 23 ]. Dry matter (ISO 6496/2001) and ash (ISO 2171/2010) were determined by the gravimetric method, crude protein (ISO 5983-2/2009) was analyzed by the Kjeldahl method, and ether extractives were performed by extraction in organic solvents (SR ISO 6492/2001).…”

Effects of brown seaweed products on growth performance, plasma biochemistry, immune response, and antioxidant capacity of broiler chickens challenged with heat stress

“…However, the current increase in the incidence of heat waves due to climate change further heightens HS concerns ( Chauhan et al, 2021 ). Recently, interests have involved the extensive use of bioactive substances to ameliorate HS in poultry ( Saracila et al, 2021 ) due to their beneficial effects on health and production ( Abdelli et al, 2021 ). These phytogenic feed additives can be incorporated into animal feed or water as extracts ( Gadde et al, 2017 ).…”

Effect of dietary supplementation of some antioxidant combinations on nutrient digestibility in heat-stressed broilers

“…Contrary to our findings on liver crude fat, other authors have shown different results on deposit tissues (breast and thigh). For example, some authors showed that Cr-Zn and Cr-VC supplementation to the diet of heat stressed broiler decreased the content of crude fat in breast (Untea et al, 2021) and thigh meat (Saracila et al, 2021a).…”

“…Creeping wood sorrel (Oxalis corniculata, CWS) contains a wide range of phytochemicals with antioxidant properties such as flavonoids, tannins, phytosterols, polyphenols, glycosides (Sharma & Kumari, 2014). Recent studies (Saracila et al, 2020;2021a;Untea et al, 2021) have shown that diet supplemented with Cr picolinate and CWS had a positive effect on meat quality from heat-stressed broilers.…”
