Abstract: One hundred twenty-five Angus crossbred steers (215 +/- 2 kg initial BW) were blocked by weight and assigned to pens. Pens were randomly assigned to treatment (six pens/treatment). Treatments consisted of 1) control (no supplemental Cr), 2) CrCl3, 3) high-Cr yeast, or 4) Cr nicotinic acid complex. Chromium was added to provide .4 mg of supplemental Cr/kg of DM. Steers were fed diets containing 90% corn silage (DM basis) and 10% soybean meal-mineral-vitamin supplement. Steers were allowed to consume the diets o… Show more

“…It has been reported that supplemental Cr feeding may improve body weight and feed efficiency in pigs (Page et al, 1993), broiler chickens (Ahmed et al, 2005), goats (Paul et al, 2005) and dairy heifers (Biswas et al, 2006). On the other hand Cr supplementation has been found to have no relationship with body weight and associated performance traits in ruminating feeder calves (Bunting et al, 1994;Kegley and Spears, 1995), steers (Besong et al, 2001), dairy cows (Hayirli et al, 2001) and sheep (Kitchalong et al, 1995;Sano et al, 2000). Achieving discernible effects of supplemental Cr on the production and metabolic indices of adult ruminants is still a debatable issue owing to the fact that functional ruminants derive little glucose from intestinal absorption, and the role of insulin in ruminants is perhaps less well defined than that in non-ruminants (Brockman, 1986).…”

“…In contrast, Cr supplementation (3 mg/d; as a high-Cr yeast) did not affect Con A, phytohaemagglutinin (PHA), or pokeweed (Phytolacca americana) mitogen (PWM)-induced blastogenesis of lymphocytes obtained from calves following inoculation with bovine herpesvirus-1 (Arthington et al 1997). Other studies in cattle have reported no effect of Cr supplementation (0·4 mg/kg; as either a Cr-nicotinic acid complex, high-Cr yeast or CrCl 3 ) on PHA or PWM-stimulated lymphocyte blastogenesis (Kegley & Spears, 1995;Kegley et al 1996).…”

“…Cr supplementation in cattle decreased serum cortisol concentrations in some studies (Chang & Mowat, 1992;Moonsie-Shageer & Mowat, 1993;Kegley et al 1996), but not in others (Lindell et al 1994;Kegley & Spears, 1995;Kegley et al 1997). When serial blood samples were obtained from jugular-cannulated calves at 4 h intervals for 6 d Cr supplementation (high-Cr yeast) did not affect serum cortisol concentrations following inoculation with bovine herpesvirus-1 (Arthington et al 1997).…”

“…Vários autores não têm verificado efeito da suplementação de cromo no desempenho de bezerros em condições de conforto (Kegley & Spears, 1995;Depew et al, 1998;Danielsson & Pehrson, 1998). Entretanto, Moonsie-Shageer & Mowat (1993), encontraram aumento no ganho de peso diário, bem como na ingestão de alimentos por bezerros submetidos a estresse, mas não em situações normais.…”

“…Claeys et al (1994) e Depew et al (1998) também não encontraram diferença significativa no desaparecimento da glicose sangüínea. A tendência de desaparecimento mais rápido da glicose sangüínea é possivelmente devido a um aumento na atividade da insulina, como foi encontrado por Hayirli et al (2001), suplementando vacas leiteiras no período do pré-parto com cromo-metionina e também por Kegley & Spears (1995), que, suplementando bezerros mestiços Angus com cromo orgânico, por período de 56 dias, encontraram aumento no nível de insulina sérica, entre 15 e 30 minutos após a infusão de glicose.…”
