“…In our study, the Cr contents of breast meat and blood were very significantly increased with the inorganic and CEBS supplemented. Our results here showed that the supplemental Cr in CEBS had a significant influence on Cr content of breast muscle in agreement with a previous report [28]. The effect of CEBS was greater than for inorganic Cr in this experiment, suggesting that CEBS had greater bioavailability as a Cr resource.…”

BackgroundBoth chromium (Cr) and probiotic bacillus own the virtues of regulating animal metabolism and meat quality. Purpose of this study was to evaluate the efficiency of supplemental Cr and bacillus in the form of chromium-enriched Bacillus subtilis KT260179 (CEBS) on chicken growth performance, plasma lipid parameters, tissue chromium levels, cecal bacterial composition and breast meat quality.MethodsSix hundred of 1-day-old Chinese Huainan Partridge chickens were divided into four groups randomly: Control, inorganic Cr, Bacillus subtilis, and CEBS. The feed duration was 56 days.ResultsAfter 28 days of treatment, broiler feed CEBS or normal B. subtilis had higher body weights than control broiler, and after 56 days, chickens given either CEBS or B. subtilis had greater body weights than control broiler or those given inorganic Cr. Plasma total cholesterol, triglycerides, and low density lipoprotein cholesterol levels declined significantly in the CEBS group compared with the control, whereas plasma high density lipoprotein cholesterol levels increased significantly. The concentration of Cr in blood and breast muscle increased after CEBS and inorganic Cr supplementation. B. subtilis and CEBS supplementation caused a significant increase in the numbers of Lactobacillus and Bifidobacterium in the caecum, while the numbers of Escherichia coli and Salmonella decreased significantly compared to the control. Feed adding CEBS increased the lightness, redness, and yellowness of breast meat, improved the water-holding capacity, decreased the shear force and cooking loss.ConclusionsIn all, CEBS supplementation promoted body growth, improved plasma lipid parameters, increased tissue Cr concentrations, altered cecal bacterial composition and improved breast meat quality.

Trivalent chromium is considered an essential element in the nutrition of both animals and humans. Animal studies confirm many beneficial effects of organic and inorganic chromium compounds on carbohydrate, protein and lipid metabolism in the body. Glucose tolerance factor (GTF) has been demonstrated to involve an active form of trivalent chromium, which sustains normal glucose metabolism. Cr(III) compounds form enzymes and ribonucleic acids, accelerate blood clotting and increase β-glucuronidase activity. Chromium also participates in antioxidant processes, in the synthesis of RNA and DNA and in the immune response, as well as affects secretion of hormones and some vitamins. It has been demonstrated that chromium improves lean body mass in animals, increases growth rate and feed conversion and improves feed intake and energy efficiency. Organic chromium reduces mortality and improves animal reproduction parameters. It also enhances immunity and strengthens response to preventive vaccination. It has been noted in many animal species that a diet low in chromium leads to deficiency symptoms, such as reduced feed intake, lower weight gains, reproductive disorders and increased lipid levels. Chromium deficiency can also result from stress. Moderate chromium deficiency is a risk factor of ischemic heart disease with myocardial infarction. Such a condition may pose a great risk of coronary artery disease. Dietary chromium requirement of an animal body is probably 300 μg Cr/kg d.w. of feed, which is usually satisfied by the ration provided. The highest concentration of chromium is found in the hair, skin and teeth, followed by the liver, kidneys, spleen, and slightly lower in the heart, muscles, pancreas, lungs, bones and brain. Chromium absorption rates in the human intestine range between 0.5 and 2% of the daily intake of inorganic Cr forms, and from 25 to 30% of the element ingested as organic complexes. Clinical studies show that the kinetics of chromium excretion from the system are complex and can be described by a multi-range model, the half-life ranging from 13 min to 192 days. Dietary chromium nanocomposite supplementation (CrNano) used in pigs nutrition has significantly increased Cr content in the blood, longissimus muscle, heart, liver, kidneys, jejunum and ileum. Chromium nanocomposite supplementation acts more effectively on the tissues and, as a consequence, increases the accumulation of the element. .

“…In mouse, Anderson et al (1989) reported that supplemental chromium resulted in an accumulation of Cr in the liver. Zha et al (2007c) reported that nanoparticles chromium supplementation shown effects on primary tissues such as kidney, liver and hind leg muscle in rats. In addition, Cr has been shown that supplemental chromium led to increased Cr and Zn in serum, liver, kidney and longissimus muscle of laying hens and Japanese quails (Sahin et al, 2002a;Sahin et al, 2002b), but Fe concentrations were not affected in Japanese quails.…”

This study was conducted to investigate the effects of various levels of nanoparticles chromium picolinate on performance, egg quality, minerals retention, and tissues accumulation of layer chickens. This study used 54 seventy-week old post-molt laying hens randomly allocated into 0 (control), 500 ppb (µg kg -1 ) Cr and 3000 ppb Cr groups for a 60-day experiment. The chromium was nanosize (80.8 ± 2.7 nm) chromium picolinate (NanoCrPic) and each treatment was undertaken with six replicates. In the meantime, a total of 18 birds (1 bird/replicate) were used for metabolic experimentation. The results of the experiment indicated that there were no significant effects on body weight, feed intake, feed efficiency, and egg production of layers. Supplemental NanoCrPic could significantly (p < 0.05) improve egg quality, or retention of chromium and zinc, but decrease shell ratio in the 60 th day eggs. The addition of NanoCrPic resulted in increased minerals accumulation in tissues such as Cr, Ca, and P concentration in the liver, Cr concentration in the yolk and Ca concentration in the eggshell. In conclusion, supplemental NanoCrPic improved Cr and Ca accumulation in the liver and egg, improved Zn and Mn retention in layer chickens.
