“…Lien et al (1999) reported that 1600 and 3200 µg/Cr Pic supplementation in a broiler diets increased feed intake and improved live weight gain. Kim et al (1996) also observed that 1600 µg/Cr picolinate supplementation increased the weight gain and feed intake without affecting feed conversion in broilers. It has been shown that Cr supplementation cause significant changes in the chemical composition of animal carcasses (Lukaski, 1999).…”

The present study aimed to the effects of chromium (Cr) supplementation with different levels on growth performance, digestibility nutrients, carcass characteristics, some blood constituents and economic efficiency of the growing Japanese quail. A total number of 450 one-day-old Japanese quail's chicks was used divided randomly into five experimental groups. Each group was distributed by 3 replicates pens containing (30 birds in each) until 6 weeks of age. The 1 st group fed the basal experimental diet without supplementation (as control), while the other groups were fed on diets supplemented with 200, 400, 800, and1200 µg chromium (Cr)/kg ration as chromium picolinate (Cr pic.), respectively. The results showed that the addition of chromium in the diets of growing Japanese quail resulted in an improvement (P<0.05) in body weight, and weight gain of group which received 1200 µg Cr/kg diet as compared to control one at the first three and six weeks of age. Moreover, at the same level addition of chromium in quail diets significantly (P≤0.05) improved the feed conversion, protein efficiency ratio and efficiency of energy utilization when compared with those fed unsupplemental diet, during the experimental periods (0-3 and 0-6 weeks of age). However, the addition up to 800 µg /kg of Cr in the diets improved significantly (P<0.05) the digestibility of organic matter and nitrogen free extract, while crude protein, crude fibre and ether extract digestibility were insignificantly affected. The results, also demonstrated that the abdominal fat decreased as the levels of chromium increased while, carcass percentage was increased. Serum total cholesterol, glucose were significantly (P<0.05) decreased by Cr supplementation. On the other hand total lipid, total tri-glycerides and high density lipoprotein cholesterol (HDL %) showed the inverse trend. The highest value of economic efficiency (EE) was obtained for quails fed on diets supplemented by Cr up to 800 µg /kg. The results from this study demonstrate that a supplementation up to 800 µg /kg of Cr in the ration improved the growth performance, digestibility, carcass characteristics and blood constituents of the growing Japanese quail.

“…Por outro lado, Sands & Smith (2002) utilizaram picolinato de cromo e manganês proteinado na dieta de frangos de corte e não observaram variação nas concentrações sorológicas de ácidos graxos não-esterificados, triglicérides, HDL e colesterol total, porém os níveis de ácidos graxos não-esterificados tenderam a uma diminuição. Kim et al (1995) relataram aumento dos níveis de HDL, redução do colesterol total e elevada relação HDL:CHOL em frangos sob suplementação com picolinato de cromo.…”

RESUMO -Avaliou-se o efeito da suplementação de cromo na dieta sobre o desempenho, o rendimento de carcaça, a qualidade da carne, o teor de colesterol no peito e os parâmetros bioquímicos do sangue de frangos de corte. O delineamento experimental utilizado foi o inteiramente casualizado, com cinco níveis de tripicolinato de cromo (0, 150, 300, 450 e 600 μg/kg de cromo) e seis repetições de 50 aves por unidade experimental. A utilização do tripicolinato de cromo não teve efeito no desempenho dos frangos de corte. Os níveis de cromo não influenciaram o rendimento de carcaça nem o pH do peito dos frangos aos 42 dias de idade. Em avaliação da composição de matéria seca, proteína bruta e extrato etéreo da carne de peito, apenas a porcentagem de extrato etéreo foi influenciada, e de forma quadrática, pelos níveis de cromo na dieta.O nível de 218,2 μg de cromo diminuiu a porcentagem de extrato etéreo em 7,03 em comparação à ausência de cromo.A suplementação de cromo nas dietas não influenciou o teor de colesterol total na carne do peito, mas alterou os níveis de HDL aos 14 dias de idade e os de VLDL e os triglicérides aos 21 dias de idade. A suplementação dietética de cromo não influenciou o desempenho e rendimento de carcaça. Níveis entre 218,2 e 360,3 ìg de cromo interferem no teor de gordura da carne e nos níveis de lipídeos do sangue dos frangos de corte.Palavras-chave: colesterol na carne, desempenho, lipídeos, rendimento de carcaça Chromium influence on performance, meat quality and concentration of lipids in broiler blood plasmaABSTRACT -The aim of this work was to evaluate the effect of dietary chromium supplementation on performance, carcass yield, meat quality, cholesterol level on the breast and blood biochemical parameters on broilers. It was used a complete randomized experimental design with five levels of chromium tripicolinate (0, 150, 300, 450 and 600 μg/kg of chromium) and six replicates with 50 broilers per experimental unit. The use of chromium tripicolinate had no effect on the performance of broilers. The levels of chromium did not change the carcass yield neither the breast pH of the broilers at 42 days of age.At evaluation of dry matter composition, crude protein and ether extract of breast meal, only the percentage of ether extract was quadractly affected by the dietary chromium level. Chromium level of 218.2 μg reduced the ether extract percentage by 7.03 when compared to the lack of chromium. The addition of chromium in the diets did not influence the total cholesterol level in the breast meat but it did change the levels of HDL at 14 old, the VLDL and triglicerides at 21 days old. The dietery suplementation of chromium did not influence the performance neither the carcass yield. Levels of chromium ranging from 218.2 to 360.3 ì g affects fat meat and levels of blood lipids of broiler chickens.

Three hundred female broilers were assigned to five groups with six replicates and were fed with either a basal diet (two control groups) or the basal diet supplemented with 800-mg vitamin C/kg (Vit C group), 1,200-μg Cr(+3) from chromium (Cr) chloride/kg (Cr group) or 800-mg Vit C and 1,200-μg Cr(+3) from Cr chloride/kg (Vit C + Cr group) from 42 to 49 days of age. Treatments did not affect performance. Transport decreased insulin level in the control and Cr groups and increased glucose/insulin (G/I) ratio in the groups. The level of insulin was higher in the Vit C + Cr group than those in the control and Cr groups after the transport. The G/I ratio was lowest in the Vit C + Cr group after the transport. The transport significantly decreased triiodothyronine (T3) concentration in the groups except the Vit C + Cr group and only increased thyroxin (T4) concentration in the Vit C + Cr group. The T3/T4 ratio was significantly decreased in the groups except the Cr group by transport. The T3/T4 ratio was greatest in the Vit C + Cr group before the transport. Alkaline phosphatase activity was decreased in the Vit C + Cr group due to transport. Transport decreased triglyceride levels in the groups and also decreased low-density lipoprotein cholesterol levels in the Vit-C-supplemented groups. Transport increased malondialdehyde concentration in the control and Vit C groups and also increased glutathione peroxidase (GPx) activity in the Cr-fed groups. The GPx activity was higher in the Vit C + Cr group than those in the control and Cr groups after the transport. Ferric reducing/antioxidant power (FRAP) value was decreased in the Vit C and Cr groups by transport. Either alone or in combination, Cr increased the FRAP value before the transport. Neither transport nor treatments had significant effects on the duration of tonic immobility (TI) and number of inductions to induce TI.
