A 4-year experiment has been conducted on finishing Belgian Blue cull cows of double-muscled type in order to study the effects of diets containing adequate levels of metabolizable protein, but either normal (NENP), low (LENP) or medium (MENP) levels of metabolizable energy, on animal performance, carcass and meat characteristics, and plasma metabolites and hormones. The LENP diet was offered during the whole (LENP group) or second half of the finishing (NENP-LENP groups), and the MENP diet during the whole finishing (MENP group). The degree of fatness required for the slaughter of animals from NENP groups was close to 4.5 (scale from 0 (very lean) to 5 (very fat)). In each underfed group, the slaughter of the animals was synchronized to that of NENP cows, by degressive degree of fatness. The same duration of finishing was thus obtained for all groups. The experimental feeding strategies reduced the amounts of fat deposited in the carcass and the meat while muscle deposition was remarkably preserved. The proportions of saturated and monounsaturated fatty acids in intramuscular fat were also decreased while their proportions increased in plasma free fatty acids. Plasma insulin levels were also reduced and those of IGF-1 were, surprisingly, maintained. The low energy diet promoted thus the settlement of a discrete lipolytic state while high levels of IGF-1 preserved muscle deposition. This feeding strategy should be evaluated in other breeds of cattle. [less ▲]

Forty-three cattle seronegative to bovine herpesvirus-1 (BHV-1) were given from one to five intradermal injections of BHV-1 inactivated antigen at four-week intervals. This delayed hypersensitivity test was assessed by the increase in skin thickness. The activity of the antigen was assessed in five animals which had a previous natural BHV-1 infection with clinical signs and seroconversion. Anti-BHV-1 antibodies were detected by seroneutralisation and an enzyme-linked immunoassay. Only one animal showed a significant but slight increase in skin thickness after the first test, but it was negative after a second test. The animals remained seronegative after the first test. Seroconversion was identified in 11 of the 43 animals (25 per cent) submitted to repeated delayed hypersensitivity tests. Five of 37 animals seroconverted after only two tests. The serological response was transient in seven of 11 seroconverted calves. Repeated hypersensitivity tests were therefore able to induce a serological response in seronegative calves but the response was weak and often transient. The test must therefore be applied cautiously to seronegative animals. [less ▲]

Dandruff is known to be controlled by fungistatic shampoos active against Malassezia spp. These products also remove the loosely attached scales. This study was performed to assess the effect of a 5-min residence time on the efficacy of antidandruff shampoos. Two commercially available shampoos were used in two groups of 21 panelists with severe dandruff. They contained either 1% ketoconazole or 1% piroctone olamine. In each group, intraindividual comparisons were made by a split-scalp design between the effect of a 5-min residence time versus no residence time. Both shampoos induced significant reductions in scaliness and yeast colonization. The beneficial effects were obvious immediately after one single shampooing and 3 days later as well. The improvement was greater with a 5-min residence time. The piroctone olamine treatment benefited more than the ketoconazole treatment from the extension of shampoo-exposure time. In conclusion, the benefit of a residence time in treating dandruff is documented. The level of improvement in efficacy may vary according to the nature of the shampoo. [less ▲]

The aim of the present study was to evaluate the effect of restraint stress, which is commonly practised in the field, on plasma concentrations of cortisol, progesterone (P4) and bovine pregnancy-associated glycoprotein-1 (boPAG-1) in pregnant heifers between Days 30 to 40 of gestation. Twelve Holstein-Friesian heifers between Days 30 (Day 0 of experiment) and 40 (Day 10 of experiment) of pregnancy in a Hungarian dairy farm were used in the present study. The heifers were exposed to an acute stressor consisting of immobilisation (restraint stress) in a crush for 2 h (Group 1, n = 6) on Day 2 (Hour 48) and for 2 × 2 h (Group 2, n = 6) on Days 2 and 3 (Hour 72) of the experiment. Transrectal ultrasonography (7.5 MHz linear-array rectal transducer) was performed daily from Day 0 to Day 10 of the experiment to detect embryonic heartbeat or the fate of the conceptus. Blood samples were withdrawn before each ultrasonographic examination. Additional blood samples were withdrawn by 1 and 2 h (at Hours 49 and 50 in Groups 1 and 2 and Hours 73 and 74 in Group 2) of the onset of applying the stressor. Plasma cortisol, P4 and boPAG-1 concentrations were measured by radioimmunoassay. Acute restraint stress significantly (P < 0.001) increased the plasma cortisol level in pregnant heifers at 1 h of the exposure to the stressor at Days 2 (48 h) and 3 (72 h) of the experiment. On the other hand, the restraint stress did not affect the concentration of P4 and boPAG-1 concentrations in both groups. In conclusion, restraint stress for 2 h during early pregnancy in heifers increased blood cortisol, but it did not affect the concentrations of P4 and boPAG-1 between Days 30 to 40 of gestation.

OBJECTIVE: Rimonabant, the first selective cannabinoid type 1 (CB1) receptor blocker, has been shown to improve multiple cardiometabolic risk factors in overweight/obese patients. This analysis assessed the impact of rimonabant on blood pressure in the pooled population from four large trials with similar design - the Rimonabant-In-Obesity (RIO) programme. METHODS: RIO-Europe (n = 1507) and RIO-North America (n = 3040) recruited overweight/obese patients, and RIO-Lipids (n = 1033) and RIO-Diabetes (n = 1045) recruited overweight/obese patients with untreated dyslipidaemia or type 2 diabetes, respectively. At study entry (screening), 37.2% (n = 2463) of patients had hypertension, 71.4% (n = 1757) of whom were taking an antihypertensive treatment. RESULTS: After 1 year of treatment, mean change in systolic blood pressure (SBP) from baseline was -0.8 mmHg for rimonabant 20 mg versus +0.3 mmHg for placebo (P = 0.007); diastolic blood pressure (DBP) decreased by -0.8 versus -0.3 mmHg (P = 0.029) respectively. In the subgroup of patients with high blood pressure at baseline, SBP change was -7.5 mmHg for rimonabant 20 mg versus -4.7 mmHg for placebo (P = 0.005); DBP change was -5.2 versus -3.0 mmHg (P < 0.001). Reductions were more pronounced in patients with dyslipidaemia and type 2 diabetes. There was no effect of rimonabant 20 mg on blood pressure beyond that expected from weight loss alone. Overall, there was a similar incidence of adverse events (AEs) at 1 year in the placebo (81.8%) and rimonabant 20 mg (86.0%). The most common AEs occurring with rimonabant were nausea, dizziness, arthralgia and diarrhoea. A slightly higher proportion of patients in the rimonabant 20 mg group discontinued as a result of AEs (13.8%) versus placebo (7.2%). CONCLUSIONS: Rimonabant 20 mg led to modest, but significant SBP and DBP reductions in overweight/obese patients. The effect of rimonabant on blood pressure appears to be mediated by weight loss.

BACKGROUND: Risedronate increases bone mineral density in elderly women, but whether it prevents hip fracture is not known. METHODS: We studied 5445 women 70 to 79 years old who had osteoporosis (indicated by a T score for bone mineral density at the femoral neck that was more than 4 SD below the mean peak value in young adults [-4] or lower than -3 plus a nonskeletal risk factor for hip fracture, such as poor gait or a propensity to fall) and 3886 women at least 80 years old who had at least one nonskeletal risk factor for hip fracture or low bone mineral density at the femoral neck (T score, lower than -4 or lower than -3 plus a hip-axis length of 11.1 cm or greater). The women were randomly assigned to receive treatment with oral risedronate (2.5 or 5.0 mg daily) or placebo for three years. The primary end point was the occurrence of hip fracture. RESULTS: Overall, the incidence of hip fracture among all the women assigned to risedronate was 2.8 percent, as compared with 3.9 percent among those assigned to placebo (relative risk, 0.7; 95 percent confidence interval, 0.6 to 0.9; P=0.02). In the group of women with osteoporosis (those 70 to 79 years old), the incidence of hip fracture among those assigned to risedronate was 1.9 percent, as compared with 3.2 percent among those assigned to placebo (relative risk, 0.6; 95 percent confidence interval, 0.4 to 0.9; P=0.009). In the group of women selected primarily on the basis of nonskeletal risk factors (those at least 80 years of age), the incidence of hip fracture was 4.2 percent among those assigned to risedronate and 5.1 percent among those assigned to placebo (P=0.35). CONCLUSIONS: Risedronate significantly reduces the risk of hip fracture among elderly women with confirmed osteoporosis but not among elderly women selected primarily on the basis of risk factors other than low bone mineral density.

Current theories on the alternative mating tactics suppose that individuals may opt for particular behavioral patterns depending of their morphological status. Facultative paedomorphosis in newts and salamanders is a suitable process to explore this question because it implies the coexistence of two different morphological morphs differing by the presence of gills and epigamic traits. The aim of this study was to find out whether paedomorphs and metamorphs use similar tactics to attract mates in the presence of a rival and whether there are differences in sexual activity and success between alternative morphs. Sexual interactions in triadic encounters were staged and analyzed in a standardized experimental design. The two kinds of males did not differ in terms of sexual activity, spermatophore deposition or female responsiveness. Both rival paedomorphic and metamorphic males exhibited sexual interference, but in most encounters, intruders just disturbed the courting pair. Sperm transfer success was lower in triadic encounters than in dyadic encounters. These results illustrate that intermorph breeding also occurs in the presence of competitors but that the success rate of the newts is considerably decreased in such competitive situations. Moreover, newts do not use alternative reproductive tactics depending on their status (i.e., paedomorph or metamorph). [less ▲]

Two trials were conducted to evaluate the effect of rumen-degradable protein balance (OEB) deficit on voluntary intake (trial 1), microbial protein synthesis, andNmetabolism (trial 2) in growing doublemuscled Belgian Blue bulls. In trial 1, six bulls (339 ± 26 kg of initial BW) were used in a replicated 3 × 3 Latin square and received a diet of 60% corn silage and 40% concentrate with ad libitum intake (DM basis). Three concentrates were formulated by adding urea at the expense of barley to give similar dietary contents of intestinal digestible proteins, NE for fattening, and fermentable OM, but with different levels of OEB. Thus, 2 levels of OEB deficit (−23.7 and −9.2 g of OEB/kg of DM) were compared with a diet providing a slight OEB surplus (5.3 g of OEB/kg of DM). Voluntary DMI decreased linearly (P = 0.02) with decreasing rumen-degradable protein balance. This decrease in intake could explain the linear decrease in ADG observed when negative OEB diets were fed. In trial 2, six bulls (304 ± 12 kg of initial BW) with cannulas in the rumen and proximal duodenum were used in a replicated 3 × 3 Latin square and fed diets similar to those used in trial 1 at an intake level of 85 g of DM/kg of BW0.75. Diurnal variations of ruminal NH3-N and plasma urea-N concentrations were greatly influenced by the level of OEB in the diet. No differences in NDF and starch degradation in the rumen, microbial N flow at the duodenum, or efficiency of microbial protein synthesis in the rumen were noted among the levels of OEB in diets. The reductions of the OEB value from 5.3 g/kg of DM to −9.2 g/ kg of DM and −23.7 g/kg of DM were associated with reductions of 26.5 and 48.8% in urinary Noutput. Absolute amounts of N retained by the bulls increased significantly with the level of OEB in diets. Indeed, 51.4% of the incremental supply of N was excreted between −23.7 and −9.2 g of OEB/kg of DM diets, and 74.6% of the incremental supply of N was excreted between −9.2 and 5.3 g of OEB/kg of DM diets. Feeding diets characterized by an adequate intestinal digestible protein supply and a OEB close to −10 g of OEB/kg of DM could be a feeding strategy to reduce N losses from the farm with little effect on the animal performance and voluntary intake. Reduced OEB may reduce N excretion in the environment but may also result in decreased N retention. [less ▲]
