Recent advances in role of chromium and its antioxidant combinations in poultry nutrition: A review

Abstract

Poultry is reared in open side houses in most of the tropical countries, which results in huge temperature variation in shed causing stress resulting in increased demand of antioxidant supplementation. Since cooling of poultry houses or environment control is very expensive, thus methods focused on nutritional modifications appears to be the much logical approach. Stress increases mineral and vitamin mobilization from tissues and their excretion. Effect of some minerals and vitamin supplements such as chromium (Cr) and ascorbic acid to elevate the negative effects of environmental stress is well documented. Cr functions as an antioxidant and its deficiency are said to disrupt carbohydrate and protein metabolism. Cr has been utilized for weight gain, to improve feed conversion ratio, increase relative organ weight, muscle development, decrease cholesterol, increase high-density lipoprotein cholesterol, and improve nutrient digestion. Therefore, the present review discusses the beneficial aspects of Cr with its effect in different doses and antioxidant combinations to explore and promote its optimum utilization in poultry nutrition and production.

Dietary supplementation with pioglitazone hydrochloride and chromium methionine manipulates lipid metabolism with related genes to improve the intramuscular fat and fatty acid profile of yellow‐feathered chickens

“…Decreased proportions of C14:0, C16:0 and C18:0 and increased proportions of C16:1 and C18:2n‐6 were also observed in the PGZ plus CrMet group. Collectively, these changes could be attributed to the fatty deposit capacity of PGZ and the oxidation resistance of CrMet …”

“…Following increases in IMF content, lipid oxidation is an adverse factor that damages meat quality . Chromium methionine (CrMet), in particular, has been considered one of the best options for protecting the increased IMF content from oxidation . However, studies on the antioxidant effect of CrMet have mainly focused on mammals .…”

Strategies to combat the deleterious impacts of heat stress through feed restrictions and dietary supplementation (vitamins, minerals) in broilers

“…Khan et al (2014) found that adding Cr to broiler diets increased lymphoid organ weight (spleen). The combined effects of Cr and vitamin C in broiler diets under HS improved quality and carcass traits (Haq et al, 2016). Broilers fed supplemental Cr 500, 1000, and 1500 ppb under summer conditions showed significantly improved carcass yield and reduced abdominal fat (Toghyani et al, 2006).…”

Nutritional strategies to alleviate heat stress effects through feed restrictions and feed additives (vitamins and minerals) in broilers under summer conditions

“…In addition, the positive impacts of Cr on growth performance and blood parameters have been connected to chromodulins ability to improve the sensitivity of tissue receptors to insulin (Vincent 2000). Cr participation in the metabolism of carbohydrate including glucose (uptake and utilization) for lipogenesis and glycogen production (Haq et al 2016).…”
