A 3 × 2 factorial experiment consisting three levels (0, 200, and 400 μg/kg) of chromium (chromium picolinate) and two levels (0 and 250 mg/kg) of vitamin C was employed to evaluate the effects of these dietary supplements on performance, egg quality traits, and serum biochemical parameters of heat-stressed laying hens (Lohmann LSL-Lite) from 66 to 74 weeks of age. Feed intake increased when birds were given either 400 μg/kg chromium or 250 mg/kg vitamin C (P < 0.05), but the birds that… 
Effects of dietary supplemental chromium methionine, zinc oxide, and ascorbic acid on performance, egg quality traits, and blood parameters of laying hens subjected to heat stress
ABSTRACT Based on a 2 × 2 × 2 factorial, the effects of three dietary supplemental including chromium methionine (Cr) (0 and 400 μg/kg diet), zinc oxide (Zn) (0 and 30 mg/kg diet), and vitamin C
Influence of dietary supplemental chromium and magnesium on performance and metabolic parameters of laying hens subjected to heat stress
TLDR
Diet supplementation by Mg could have beneficial effects on feed conversation ratio, shell thickness and serum uric acid, whereas diet supplementation by Cr decreased serum glucose, total cholesterol, triglycerides and uric Acid of laying hens under heat stress condition.
Dietary Supplementation with Chromium Picolinate Influences Serum Glucose and Immune Response of Brown-Egg Laying Hens
TLDR
Results from this study indicated that supplemental CrPic decreased serum GLU and enhanced the immune function of brown-egg laying hens.
Short Effects of rosemary essential oil and zinc on performance, egg quality traits, and some serum metabolites in laying hens
This study was conducted to evaluate the effects of dietary supplementation of rosemary essential oil (REO) and zinc (as zinc sulfate) on performance, egg quality traits, and some serum metabolites
Effects of the supplemental chromium form on performance and metabolic profile in laying hens exposed to heat stress
TLDR
In conclusion, HS adversely affected laying performance, egg quality, and metabolic profile in laying hens, and both CrPic and CrHis partially alleviated the adverse effect of HS on these parameters.
Organic Chromium Form Alleviates the Detrimental Effects of Heat Stress on Nutrient Digestibility and Nutrient Transporters in Laying Hens
TLDR
The detrimental effects of HS on nutrient digestibility and nutrient transporters were alleviated by CrPic and CrHis, and the efficacy of Cr as CrHis was more notable than Cr asCrPic, which could be attributed to higher bioavailability.
Dietary Supplemental Vitamin E and Chromium on Egg
Since the range of thermoneutral temperature in chicken is narrow, they become easily exposed to heat or cold environmental stress. Heat stress in particular has a highly detrimental influence on
Effects of chromium and chromium + vitamin C combination on metabolic, oxidative, and fear responses of broilers transported under summer conditions
TLDR
The duration of tonic immobility (TI) was similar between nontransported control chicks and transported chicks without any supplements and Pretreatment with Cr’+ Vit C significantly reduced the duration of TI.
INFLUENCE OF CHROMIUM SOURCES ON PERFORMANCE OF GIMMIZAH CHICKENS FED LOW METABOLIZABLE ENERGY AND CRUDE PROTEIN DIETS
This study was done to investigate the influence of chromium sources (organic; Cr-Methionine and inorganic; Crcl3) on the performance of Gimmizah chickens fed low metabolizable energy (LME) or low

The Effect of Chromium Supplementation on Egg Production, Egg Quality and Some Serum Parameters in Laying Hens
TLDR
The results of the experiment indicated that chromium supplementation to the diet of layers may be of practical value due to the slight reduction in feed consumption and improvement in efficiency of feed utilisation and reduced egg cholesterol content without any adverse effect on egg quality.
