“…There is evidence that Cr supplementation period may affect the responses of the pigs. In a 29-day trial before slaughter, Rodrigues et al (2020) did not verify any effect of CrY on growth performance. However, Boleman et al (1995) observed an increase in carcass muscle percentage and a reduction in carcass fat with a 50-day Cr supplementation; and Caramori Júnior et al (2017) reported an increase in muscle depth with a Cr supplementation period of 66 days, and Matthews et al (2001) showed an increase in carcass length with supplementation of 102 days.…”

“…Chromium increases cellular sensitivity to insulin and results in a greater cellular uptake of glucose, which provides more energy for metabolism (JACKSON et al, 2009). However, the effects of chromium supplementation on the lipid profile are inconsistent and vary with the source, dosage, and supplementation period (RODRIGUES et al, 2020). In this study, there were no differences in the lipid profiles between the two sources of chromium, when compared to that in CON and Cr YST; however, they had greater effects on the amount of fatty acids.…”

This study identified the effects of dietary supplementation with ractopamine, chromium picolinate, chromium yeast, or an energetic feed restriction on the growth performance and lipid profile of subcutaneous fat, in late finishing gilts. Twenty genetically similar gilts with initial body weight of 105.35 ± 4.77 kg and a final body weight of 131.37 ± 5.58 kg were distributed in a completely randomized block design with five treatments (control; ractopamine: 20 ppm; chromium picolinate: 0.48 ppm; chromium yeast: 0.80 ppm; and energetic feed restriction: -150 kcal kg-1 of metabolizable energy), with four replicates of one animal each. The experimental diets were isonutritives, except for the metabolizable energy level of the diet fed to the group subjected to energy restriction. There were no effects on the growth performance and carcass characteristics. Ractopamine and organic chromium (picolinate and yeast) supplementation increased the concentration of total polyunsaturated fatty acid. The proportion of α-linolenic fatty acids were higher when the diets were supplemented with ractopamine or chromium yeast. The energy restriction increased the n-6:n-3 ratio and reduced α-linolenic acid concentration. Therefore, ractopamine, chromium picolinate, chromium yeast supplementation, and energetic feed restriction did not affect the growth performance or carcass characteristics but altered the lipid profile of subcutaneous fat in finishing gilts. Ractopamine and organic chromium supplementation increased PUFA in the fat of finishing female pigs.

“…Chromium is a potential alternative (CARAMORI JÚNIOR. et al, 2017, RODRIGUES et al, 2020. Chromium acts as a glucose tolerance factor (GTF), increasing the fluidity of the cell membrane, enabling the insulin receptor binding (EVANS & BOWMAN, 1992) and promoting the synthesis of muscle proteins.…”

This study evaluated chromium supplements and energy restriction as substitutes for ractopamine in the diets of late finishing gilts. Sixty gilts were used, with initial weights of 98.87 ± 0.25 kg and final weights of 122.69 ± 10.97 kg, distributed in a randomized block design with five diets: control; yeast chromium (0.8 ppm); chromium picolinate (0.48 ppm); ractopamine (20 ppm) and energy restriction (reduction of 150 kcal of EM kg-1 of feed), with six replicates and two animals per experimental unit. Feeding diet containing ractopamine enabled better (P<0.05) feed conversion and greater weights of the hot carcass of the gilts. The diet containing ractopamine exhibited a lower (P<0.05) cost of feed per kilogram of gain and higher economic efficiency, when compared to diets containing chromium and energy restriction; these exhibited better outcomes, compared to the control diet. Diets supplemented with chromium and ractopamine resulted in a higher (P<0.05) percentage and quantity of lean meat and a higher rate of carcass bonus, when compared to the control diet and energy restriction. The energy reduction did not harm the gilts’ responses, compared to the control diet. Ractopamine supplementation allowed for a better feed conversion, lower feed cost per kilogram of gain, and a higher economic efficiency index. Supplements of chromium and ractopamine increased the percentage and quantity of lean meat and the bonus index of the carcasses. Therefore, chromium picolinate and chromium yeast are potential substitutes for ractopamine for optimizing the gilts carcass characteristics.
