“…Vit.E has the antioxidant impact on broilers by improving in the secretion of the growth hormones, feed efficiency, digestion, the hepatic, and lipid profile that reflected on blood parameters (Rehman et al 2018). Zn plays an essential role in various enzymatic activities by improving the digestion and absorption of nutrients (Naz et al 2016). 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).…”

This experiment was aimed to determine the best strategies for alleviating the detrimental effects of heat stress by feed restriction (FR) in hot times and dietary supplementation with Vit.+Min. (vitamins and minerals) by their impacts on growth parameters, mortality rate, serum biochemistry indices and carcass traits of broiler under summer conditions in the open-sided house. A total of 420 broilers of Ross 308 (unsexed 7-day-old) were equally divided into 7 treatments (T). Throughout the experiment, chicks in T1 (control) fed ad libitum on basal diets, FR was applied in T2, T3 and T4 as followed 2, 3, 4 hours (h) without feeding respectively. Supplemental vitamin C (Vit.C) + vitamin E (Vit.E) + chromium (Cr) + zinc (Zn) as followed 100+100+0.5+50 (T5), 150+150+1.0+75 (T6), 200+200+1.5+100 (T7) mg/kg diet respectively. It was found that FR and feed additives improved body weight, weight gain, and significantly decreased feed conversion, mortality rate, and abdominal fat of stressed broiler. Applying FR (3, 4 h) and supplementation with Vit.+Min. (T6, T7) significantly increased total serum protein and statically decreased total serum cholesterol. Overall results conducted that FR for 3 h (T3) and dietary supplementation (T7) have the most significant results which indicate the vital role of FR and supplementation with Vit.+Min. in stressed broilers.

“…Minerals are also beneficial for the living cell and mostly involved in the metabolic pathways and help in the regulation of metabolism (Huskisson, Maggini, & Ruf, 2007). For example, copper scavenges the free radical especially superoxide radical (Martínez & Reina, 2017) and also an important part of superoxide dismutase (Naz et al, 2016). Zinc (Zn) plays an important role in the antioxidant defence system of the body (Khan et al, 2014;Shah et al, 2018).…”

The aim of the current study was to evaluate the effect of dietary supplementation of Pinus ponderosa leaves (pine leaves) and α‐tocopherol acetate (vitamin E) powder on male reproductive system, serum metabolites and carcass characteristics of Japanese quails. A total of 360‐day‐old male quails were purchased from the open market and kept at poultry shed for ninety‐four days. After ten days of adaptation, all quails were randomly assigned into 4 groups, control (IC); supplemented with α‐tocopherol acetate (IE) at the rate of 150 mg/L; Pinus ponderosa leaves (IP) at the rate of 150 mg/L; and 70 mg α‐tocopherol acetate and 70 mg Pinus ponderosa leaves (IEP). Pinus ponderosa leaves and α‐tocopherol acetate supplementation had not significantly (p > .05) effected on final body weight gain, feed intake and feed conversion ratio of quails. The high‐density lipoprotein cholesterol (HDLC) and total cholesterol (TC) were significantly (p > .05) affected by IE and IP groups as compared to IC and IEP groups. Triglyceride (TG), glutathione peroxidase (GPx) and superoxide dismutase (SOD) significantly (p < .05) increased in all treatment groups except for the IC group. Aspartate transaminase (AST) significantly (p > .05) decreased in treatment groups as compared to control group. Overall, the mineral levels significantly (p < .05) increased in treatment groups as compared to control. Cloacal gland index values, the quantity of foam production and testis weight were significantly (p < .05) increased in treatment groups. It was concluded that the supplementation of Pinus ponderosa leaves and α‐tocopherol acetate improved the testis weight, foam production, serum antioxidant enzymes and mineral level especially zinc in Japanese quail considered an indicative characteristic of higher sperm production rate and improved sexual activity. Further, higher gametogenesis rate, sperm production or reproductive behaviour including different hormonal level will be analysed in future study.

“…Zn is also considered an indispensable component for the antioxidant system of animals (Naz et al, 2016). It is a cofactor of the enzyme SOD, which acts on the conversion of superoxide anions to hydrogen peroxide (Niles et al, 2008).…”

“…In addition, Zn increases the synthesis of metallothionein, a cysteine-rich protein that acts as a free radical scavenger (Sahin et al, 2005); and prevents the formation of hydroxyl radicals (OH.) by competing for transition metal binding sites such as iron and copper from the hydrogen peroxide (H2O2) molecule (Naz et al, 2016). Bun et al (2011) reported that supplementation of organic Zn up to 40 mg/kg of feed was effective in reducing lipid peroxidation levels measured by malondialdehyde (MDA) concentration, and increased levels of GPx and hepatic SOD.…”

Intestinal integrity, oxidative stress, and immune competence of broilers exposed to heat stress and supplemented with Zn amino acid complex To determine the effect of zinc-amino acid complex (ZnAA; Availa Zn) dietary supplementation on intestinal integrity, oxidative metabolism and performance of broilers raised under chronic cyclic heat stress, two experiments were designed; Experiment 1 was divided in two identical trials repeated over time to assess biological parameters and Experiment 2 consisted of a floor pen trial to determine performance results. For both trials of Experiment 1 the treatments followed a 4 × 2 factorial arrangement, including four levels of supplemental ZnAA (0, 20, 40 and 60mg/kg diet) and two environmental conditions (thermoneutral-TN-and a chronic cyclic heat stress-HS). The dietary treatments were applied from placement. At 21d of age, a total of 12 birds per treatment combination were randomly allotted to three battery cages in environmentally controlled rooms. TN temperature was 24 °C and HS was set to depart 9 °C. For Experiment 2, 1,800 broiler chicks were allotted into 4 treatments (levels of ZnAA) in 10 replicates of 45 birds each. All chicks used were males from Cobb 500 strain. The unsupplemented diet (0 mg ZnAA/kg) was based on corn, soybean meal, and soybean oil and was adequate in all nutrients, except Zn. As for Experiment 1, birds were fed dietary treatments from placement and heat stress protocol started at 21d of age and lasted 21 days. All the assessments were performed at 42d. HS impaired virtually all parameters assessed. HS resulted in increased body temperature and respiratory frequency; worsened performance and immunological parameters; increased oxidation products and antioxidant enzyme activity in blood (erythrocyte), liver and intestine (jejunum); impaired histomorphometry parameters as well as gut integrity. Dietary ZnAA supplementation proved to be an excellent tool for broilers under oxidative stress (caused by heat stress). It has linearly improved body weight and feed conversion ratio; linearly improved bursa relative weight and gammaglobulins quantification; linearly decreased oxidation products in blood and liver; quadratically increased antioxidant capacity in blood and influenced histomorphometric parameters differentially for thermoneutral or heat stressed birds. Under heat stress, ZnAA improved gut integrity measured by FITC-d and enhanced occludin and ZO-1 proteins quantification (Western Blot analysis). In the performance assessment (Experiment 2), supplemental ZnAA linearly increased body weight and body weight gain for the total experimental period (1 to 42). The HS treatment applied in this study has revealed to be a model of gut barrier disruptor and ROS (reactive oxygen species) generator. ZnAA supplementation, in turn, showed potential to improve immune competence of broilers raised under both environmental conditions tested, to diminish the effects of oxidative stress and improve intestinal integrity measured by FITC-d and quantification of ...
