“…This can indicate that Cr propionate has a dose-dependent effect on body weight. Our results are in consistence with previous studies on Cr supplementation in broilers ( Sands and Smith, 1999 , Sahin et al., 2003 , Toghyani et al., 2006 ).…”

There is evidence to suggest that poultry may have a dietary requirement for metabolically available chromium (Cr) that exceeds the amount provided through wheat soybean meal diets. The objective of the present study was to investigate the effects of dietary supplemental organic Cr from Cr propionate at different dose levels (control = 0 μg/kg, T1 = 200 μg/kg, T2 = 400 μg/kg) on the growth performance, carcass traits, and meat quality of broilers. Weight gain and feed intake of each treatment were recorded at the start and after 14, 28 and 35 d, and feed conversion ratios (FCR) were calculated accordingly. At 35 d of age, birds were randomly selected and euthanized for carcass evaluation. Results of the first trial indicate that both Cr propionate treatments increased final body weight ( P < 0.05), feed efficiency ( P < 0.05) and body weight gain ( P < 0.0001). Furthermore, Cr propionate supplementation improved ( P < 0.0001) all carcass characteristics. Interestingly, with increased Cr dosage, carcass yield, dressing percentage and breast meat yield increased linearly ( P < 0.0001). The second study reveals that the feed intake in the control group was significantly higher compared to both Cr propionate supplemented groups (T1 & T2). Furthermore, the Cr propionate supplemented T2 group displayed a significantly lower FCR than the control and T1 group ( P = 0.027). Finally, Cr propionate supplementation increased the dressing percentage compared to control birds ( P < 0.0001). In the third experiment, Cr propionate supplementation (T1 & T2) increased final body weight and decreased FCR compared with the control treatment. These effects were highly significant ( P < 0.0001) throughout all feeding phases of the trial. Cr propionate supplementation also increased ( P < 0.0001) carcass yield, dressing percentage, breast meat yield, leg and thigh weights compared with the control treatment. In conclusion, growth performance, feed conversion, carcass yield, breast and leg meats of broiler birds can be significantly improved by dietary inclusion of Cr propionate. Cr propionate can be supplemented to broiler birds from 1 d old of age at a level that provides 200 or 400 μg/kg organic Cr and can increase the efficiency of broiler production.

“…However supplemented groups had lower FCR than the control group and T 1 and T 2 recorded same FCR. Toghyani et al (2006);Chaudhari et al (2006); Anandhi et al (2006) and Suksombat and Kanchanatawee (2005) however, observed the non-significant effect on weekly feed conversion ratio in the chromium supplemented broilers and their observations are in tune with present findings. The findings of present experiment were found contrary to Samanta et al (2008) who observed the significantly improved feed conversion ratio in broilers at 2nd, 3 rd and 5 th week, however, Kaoud (2010) observed increased feed conversion ratio only at 3 rd week in broilers.…”

| The present study was conducted to evaluate the impacts of dietary supplementation of chromium yeast alone and in combination with antioxidants on growth, feed conversion and nitrogen retention in broilers during winter season. A total of 180, Cob-400 straight run broiler chicks at one day-old, were randomly distributed into four equal groups replicated three times with 15 birds per replicate. The treatments consisted of 4 experimental groups as follows: T 0 , T 1 , T 2 and T 3 . Chicks were fed corn-soya based broiler mash (basal diet) maintained as control (T 0 ), the basal diet supplemented with chromium (Cr)at 0.5 mg Cr/kg diet from chromium yeast (T 1 ), the basal diet + 0.5 mg Cr /kg diet from chromium yeast + 250 mg of ascorbic acid /kg of diet (T 2 ), and the basal diet + 0.5 mg Cr /kg diet from chromium yeast + 250 mg vitamin E /kg of diet (T 3 ). Body weight and feed consumption were recorded to evaluate the growth performance and feed conversion ratio (FCR). Nitrogen retention was observed by conducting metabolic trial during 6 th week. The climatic data revealed that there were huge variations in house air temperatures within a day. In house relative humidity ranged from 29.01% to 44.21% during the experimental period. The average weight gains were numerically higher and FCR values were lower in supplemented groups particularly in T 2 group than T 0 group. The significantly higher (p< 0.05) nitrogen retention values were recorded in T 2 group followed by T 1 than T 0 group. It was concluded that Cr in combination with ascorbic acid yielded better results in terms of performance in broilers, thus suggesting some synergetic action of both Cr and ascorbic acid that need to investigate further with specially designed projects.

“…Heat stress (36°C), applied for 10 h per day from the 21 th to the 42 nd days of life decreased performance parameters in broilers in the present study. These data are in agreement with those reported elsewhere in similar contexts [5,6,27,28] . Chromium was reported to modulate feed intake of heat stressed chickens [27,29,30] , and our findings are corresponded with those documents.…”

This experiment conducted to investigate the effects of dietary chromium (III) picolinate (CrPic) and chromium (III) picolinate nanoparticles (NanoCrPic) supplementation on growth performance, organs weight and immune function of broilers exposed to heat stress. Heat stress (36°C) was applied for 10 h per day from the 21 th to the 42 nd days. Among 8 experimental treatments; only group T1 represented the non-heat stressed control group fed with a basal diet in comfort zone whereas group T2 represented the heat stressed control group fed with a basal diet. Heat stressed T3, T4, T5 groups were fed with basal diet supplemented with 500, 1.000, 1.500 ppb of CrPic/kg while T6, T7, T8 groups were fed with bsal diet supplemeted with 500, 1.000, 1.500 ppb of NanoCrPic/kg respectively. Results of the current experiment showed that the non-heat stressed group had a higher final BW, daily weight gain and daily feed intake compared with heat stressed groups during the experiment period (d 21-42), Among heat stressed groups, FCR values improved by supplementation of Cr into the diet. NanoCrPic 1.500 treatment had the lowest (P<0.05) FCR (2.14) of the total experimental period among heat stressed groups. The liver weight values of the day 35 of experiment differed significantly (P<0.05). Serum complement component C3 of experimental broilers was severely affected by the Cr supplementation. The results indicated that the nanoparticle supplementation might be an influential method for reduction of heat stress induced disorders which may attribute to the lowering of FCR and provoking the hepatic related alteration including the liver weigth.
