“…Messenger RNA and protein levels of TNFα were shown to be highly induced in adipose tissue from obese and diabetic rodents (Hotamisligil et al., 1993). Ebara et al. (2010) reported that intramuscular adipose size of longissimus muscle was 1.82‐fold larger in F1 steers fed mainly with concentrate than in those fed with only roughage at 10 months of age and also that the expression of peroxisome proliferator‐activated receptor gamma 2, CCAAT/enhancer‐binding protein alpha, stearoyl‐CoA desaturase, glucose‐6‐phosphate dehydrogenase, fatty acid synthase and leptin genes was significantly greater in F1 steers fed mainly with concentrate than in those fed with only roughage at the same age.…”

The objective was to investigate the impact of nutrient intake during the early growth period on the expression of glucose metabolism-related genes in skeletal muscle of cross-bred cattle. From 1.5 to 5 months of age, group H (n=7) animals were intensively fed a high-protein and low-fat milk replacer [crude protein (CP) 28%; ether extracts (EE) 18%; max: 2.0 kg, 12 l/day], and group R (n=7) animals were fed a restricted amount of normal milk replacer (CP 25%; EE 23%; max 0.5 kg, 4 l/day). From 6 to 10 months of age, group H cattle were fed a high-nutrition total mixed ration mainly prepared from grain feed, and group R cattle were fed only roughage. Blood samples were taken from each animal at three biopsy times (1.5, 5 and 10 months of age), and the blood plasma concentration of glucose and insulin was analysed. In glucose concentration, there were no significant differences; however, the concentrations of insulin were higher in group H than in group R at 5 and 10 months of age. Muscle samples were taken by biopsy from longissimus thoracis muscle (LT) at 1.5, 5 and 10 months of age. We analysed mRNA expression levels using the quantitative real-time polymerase chain reaction (PCR) assay for glucose transporters (GLUT1 and GLUT4), insulin receptor, phosphatidylinositol 3-kinase (PI-3K), protein kinase B (PKB, also known as Akt), hexokinase 1 (HK1) and tumour necrosis factor alpha (TNFα). Although no differences were detected at 1.5 and 5 months of age, at 10 months of age, GLUT1, HK1 and TNFα mRNA expression levels were significantly higher in group H than in group R. These results suggested Glut1 that affects insulin-independently mediated glucose uptake was more responsive to improved nutrition during early growth stage than GLUT4 that insulin-dependently mediated glucose uptake in LT of cattle.

“…This finding suggests that increased intake in protein or energy is a crucial factor for increased plasma IGF‐I levels. In addition, on the effects of intensive feeding in calves, Ebara et al . (2010) recently reported that three‐fold intensively fed crossbred steers had a significantly greater body weight at 4 and 10 months of age, and this feeding system significantly increased mRNA expression corresponding with intramuscular adipogenesis.…”

In order to evaluate the effects of an elevated amount of modified milk replacer on body weight, daily gain, starter intake, plasma endocrine parameters and expression of nutrient transporters in small intestinal epithelia, Holstein bull calves (n=24) were fed for 60days either with the usual amount of 24% crude protein (CP) and 20% fat milk (CF) replacer (C group), or with a double amount of a modified milk replacer of 28% CP and 16% CF (E group). Body weight from D20 to D60 and daily gain before D40 was greater or tended to be greater for the E group than the C group. Plasma concentrations of insulin-like growth factor-1 (IGF-I) and insulin were greater for the E group than the C group on D28 but not on D56, without changing plasma growth hormone levels. Gene expression for sodium-dependent glucose transporter 1 and fatty acid translocase (CD36) was altered in day- and intestine-dependent manners. From these findings, we conclude that an elevated intake of milk replacer given up to 40days old is sufficient to enhance body weight, which may be associated with increased plasma IGF-I concentrations, in Holstein bulls.

Resumo -O objetivo deste trabalho foi avaliar o desempenho, as características de carcaça e as suas correlações com as expressões gênicas em tourinhos. Quarenta animais Red Norte foram confinados e distribuídos em delineamento inteiramente casualizado, em arranjo fatorial 2x2, e alimentados com grãos de soja moídos ou gordura protegida, com ou sem inclusão de monensina. As dietas foram formuladas para serem isonitrogenadas, com teores de extrato etéreo semelhante (6,5%), e tiveram silagem de milho como volumoso (40%). O período experimental foi de 84 dias, precedido por 14 dias de adaptação. Foram avaliadas as expressões dos genes PPARA, SREBP1c e SCD1. Animais alimentados com gordura protegida tiveram maior ganho de peso nos primeiros 56 dias de confinamento. O uso da monensina não afetou o ganho de peso diário dos animais, mas proporcionou aumento do rendimento de carcaça. Houve correlação de -0,40 entre o ganho de peso dos animais e a expressão do SCD1. O uso de gordura protegida aumenta o desempenho dos animais no início do confinamento, e a monensina proporciona maior rendimento de carcaça.Termos para indexação: bovinocultura de corte, gordura protegida, ionóforos, PPARA, soja, SREBP1c. Performance, carcass traits, and gene expression in young bulls fed lipids and monensinAbstract -The objective of this work was to evaluate performance, carcass traits, and their correlation with gene expression in young bulls. Forty Red Norte animals were feedlot and distributed in a completely randomized design, using a 2x2 factorial arrangement, and fed ground soybean grains or rumen-protected fat, with or without monensin supplementation. Diets were formulated to be isonitrogenous, with similar ether extract contents (6.5%), and had corn silage as roughage (40%). The experimental period lasted 84 days, preceded by 14 days of adaptation. The expressions of the PPARA, SREBP1c and SCD1 genes were evaluated. Animals fed rumen-protected fat had greater average daily gain in the first 56 days of feedlot. Monensin did not affect the daily gain, but increased carcass weight. There was -0.40 correlation between animal daily gain and SCD1 expression. The use of rumen-protected fat increases animal performance at the beginning of feedlot, and monensin provides greater carcass weight.
