Six Belgian Blue bulls (double-muscled type) and six Friesian bulls were offered a fattening diet for 34 weeks. Plasma samples were obtained once a week and also every 20 min over a 24 h period, 7 weeks before slaughter. No differences were observed between the breeds in plasma glucose, urea and free amino nitrogen concentrations, while creatinine was significantly higher in the Belgian Blue bulls. Tri-iodothyronin, tetra-iodothyronin, insulin-like growth factor 1, insulin and testosterone concentrations were higher in the Holstein group. In contrast, the Belgian Blue bulls appeared to produce more growth hormone. The slaughter weight, carcass weight, dressing percentage and proportion of lean meat were significantly higher in the Belgian Blue group. The characteristics of muscle mass (carcass weight, dressing percentage and proportion of lean meat) were positively correlated with creatinine and with the total peak area or peak amplitude of growth hormone. The insulin concentration was positively correlated with the proportion of adipose tissue in the carcass and negatively correlated with the proportion of muscle. There were no correlations between the carcass characteristics and insulin-like growth factor 1 or testosterone. No further information was provided when the ratios of the hormones were correlated with carcass characteristics. [less ▲]

Six Holstein (light-muscled type) and six Belgian Blue bulls (double-muscled type) were fed a finishing diet. Average daily gain was 1.36 kg for the Holstein bulls vs 1.24 kg for the Belgian Blue bulls (P less than .05). Holstein bulls consumed more feed (2.3 vs 1.8 kg/100 kg body weight, P less than .001) than the Belgian Blue bulls. The dressing percentage (55.4 vs 65.8%, P less than .001) and the proportion of muscle (56.1 vs 71.3%, P less than .001) in the carcass were less, whereas the proportions of adipose tissue (28.3 vs 15.4%, P less than .001) and bone (15.7 vs 13.4%, P less than .05) were higher in the Holstein bulls. Plasma creatinine determined in samples obtained once a week was lower (11.0 vs 20.3 mg/liter, P less than .001) in the Holstein bulls. In contrast, Holstein bulls tended to produce more triiodothyronine (2.3 vs 1.8 nM, P less than .10), tetraiodothyronine (71.9 vs 54.7 nM, P less than .10) and insulin-like growth factor I (IGF-I; 340 vs 205 ng/ml, P less than .20) than the Belgian Blue bulls. Growth hormone, insulin, IGF-I and testosterone were measured at 20-min intervals during two 24-h periods. In wk 6, Holstein bulls tended to produce more growth hormone than the Belgian Blues, as indicated by higher total peak area (3,185 vs 2,431 ng), peak amplitude (34.1 vs 22.6 ng/ml, P less than .10) and baseline (4.6 vs 3.3 ng/ml, P less than .20). In wk 27, the trends were opposite.(ABSTRACT TRUNCATED AT 250 WORDS) [less ▲]

A finishing diet containing barley and sugarbeet pulp 500:200 or 200:500 g/kg was given to 12 bulls twice daily at 08.00 and 16.00 h. The high-pulp diet increased rumen acetic and butyric acids and decreased propionic acid compared with the high-barley diet. The diurnal patterns over a 24-h period of rumen pH, volatile fatty acids, glucose and ammonia were characterized by 2 cycles. The high-pulp induced more even fermentations as indicated by flatter curves with less extreme values than those produced by high-barley diet. Ammonia concentration was high before feeding and decreased subsequently during 4 to 6 h after the meal. No typical patterns were observed in plasma concentrations of glucose and alpha-amino nitrogen. Plasma urea concentration increased 2 h after feeding and dropped during the following 6 to 8 h. There were no effects of dietary carbohydrate composition on growth hormone concentration but plasma insulin was significantly reduced with the high-pulp diet. Furthermore, the insulin profile showed peaks after each meal with the high-barley diet but only after the afternoon feeding with the high-pulp diet. [less ▲]

Deux taureaux Pie-Noir jumeaux monozygotes obtenus par section d'un même embryon ont été utilisés et maintenus dans les mêmes conditions expérimentales. L'un a été traité au clenbutérol, l'autre a servi de témoin. En ce qui concerne les performances zootechniques, ce sont essentiellement le rendement et la qualité de la carcasse -augmentation de la proportion de viande au détriment de la graisse- qui ont été améliorés par le traitement. Les paramètres sanguins ont peu varié. Par contre, le bilan azoté a augmenté de façon nette chez l'animal traité. Une analyse histologique de fragments musculaires a montré que la surface des fibres était plus importante chez l'animal qui avait reçu le clenbutérol. [less ▲]

Twelve (Exp. 1) and 24 (Exp. 2) young growing bulls were used to compare the effects of long-acting, cholesterol-based implants with short-acting, lactose-based implants. Each implant contained 200 mg of trenbolone acetate and 40 mg of 17 beta-estradiol. The long-acting, cholesterol-based implants were applied once either 18 wk (early implantation) or 12 wk (late implantation) before slaughter. The lactose-based pellets were implanted once (6 wk before slaughter), twice (12 and 6 wk) or three times (18, 12 and 6 wk) before slaughter. Treated animals had higher live weight gains, a lower feed conversion ratio, a higher proportion of lean meat and a lower proportion of adipose tissue than control animals. In Exp. 1 live weight gain of bulls implanted early with a single cholesterol-based implant was similar to the gain of animals treated three times with a lactose-based implant, but in Exp. 2 the effects of the long-acting implants given early were not sustained. In Exp. 3, 24 young growing bulls were used in a 3 X 2 factorial design to compare the effects of three dose levels of trenbolone acetate (100, 200 and 300 mg) and two levels of 17 beta-estradiol (40 and 60 mg). There were no significant differences between treatment groups, but highest live weight gains were observed in animals implanted with 300 mg of trenbolone and 60 mg of estradiol. This group also yielded the highest proportion of lean meat and the lowest proportion of adipose tissue. There was a decrease in plasma urea concentration after each implantation. It appeared also that plasma trenbolone was higher with implants containing 60 mg of estradiol. There were no differences between groups in growth hormone response to arginine stimulation. [less ▲]
