Purpose: Several studies have suggested that flavanols may have antiobesity effects; however, those effects clearly depend on the experimental conditions. In a previous study, we found that a single acute dose of grape seed proanthocyanidin extract (GSPE) has satiating effects. We therefore hypothesise that satiating doses of GSPE could be used to reduce body weight gain, and our present objective was to define the most effective dose. Methods: We assayed two GSPE doses in aged male Wistar rats. First we performed a subchronic (8-day) treatment by intragastric administration, which was repeated after a washout period. We measured body weight, energy intake and faeces composition; we performed indirect calorimetry; and we analysed the mRNA expression of genes involved in lipid metabolism to determine the target tissue for the GSPE. Results: We observed that 0.5 g GSPE/kg BW significantly reduced food intake and thus the amount of energy absorbed. This dosage also increased lipid oxidation in subcutaneous adipose tissue, thus causing a higher total energy expenditure. These combined effects caused a decrease in body weight. Conversely, 1 g GSPE/kg BW, which also reduced energy absorption after the first treatment, had a rebound effect on body weight gain which resulted in a lower response to the proanthocyanidin extract. That is, after the second treatment, the GSPE did not reduce the energy absorbed or modify energy expenditure and body weight. Conclusion: GSPE at a dose of 0.5 g/kg can reduce body weight by limiting food intake and activating energy expenditure in subcutaneous adipose tissue. © 2016 Springer-Verlag Berlin Heidelberg Source

A total of 26 head and body measurements and 8 indexes have been taken in 42 hens of each Balearian breed: Ibizan, Minorca and Majorcan. These hens have been bred in standard conditions. The results have shown that Ibizan has been the heaviest one, and the one which has scored the longest cranium and keel of sternum too. Furthermore it has also reported a higher tarsus diameter. Minorca has achieved the highest eye and wattle length and the biggest comb and ear lobes, the longest neck, back, tail, folding wing and thigh and the biggest ornithological measure and wingspan. Majorcan is the lightest one and it has scored minor values. Ibizan hen has obtained a higher cranium and ear lobe index. Minorca has scored the higher value for the wattle index and Majorcan has achieved a bigger comb index. Majorcan hen showed the lower chest index. Source

The presence of Apple mosaic ilarvirus (ApMV) was studied in different hazelnut cultivars growing in a trial at IRTA-Mas de Bover, Constantí (Tarragona), northeastern Spain, during a period of 9 years to test the natural transmission of the virus. Eleven cultivars from three different countries were planted in the trial. Two Spanish cultivars were infected by ApMV at the time of planting and the remaining material was ApMV free. A visual observation of leaves to check symptoms of mosaic and the enzyme linked immunosorbent assay (ELISA) to detect ApMV were periodically performed every two years. In general, no variation related to the presence of ApMV in the trial was detected. Only one tree of 'Lewis' cultivar, showing the characteristic mosaic symptoms, was positive to ApMV by ELISA in the last year. The rest of the initially healthy trees in the trial did not present any symptoms on leaves and remained free from ApMV infection. Source

Fruit set and fruit characteristics were evaluated in two self-compatible almond cultivars, 'Francolí' and 'Guara', during two years (2008 to 2009). Studies were carried out in two of IRTA's experimental orchards: Mas de Bover (Tarragona) with Mediterranean climate and Les Borges Blanques (Lleida) with continental climate. Before bloom, some branches of 'Francolí' and 'Guara' were bagged (self-pollination), and some others were marked as a control (openpollination). The number of flowers on two types of branches was noted. Bags were removed after bloom. Fruits from each branch were collected in mid August and were characterized by weight (individually and by branches), length, width, and thickness of nuts and kernels. Nearly 400 fruits from each cultivar and each pollination type were analyzed each year. No significant differences in fruit set were found between bagged and open branches for either cultivar. While both cultivars had only small differences in fruit characteristics, these were not in the same characters. Each cultivar responds differently to the pollination method. Source

1. Three experiments were carried out to study the effects of two experimental yeast cell wall (YCW) supplements, one from the yeast extract industry and the other from the brewery industry, added to maize or wheat based-diets, on performance and intestinal parameters of broiler chickens (Ross 308). 2. In the first and second experiments, a completely randomised block design with 4 experimental treatments was used: T-1) Negative control, no additives T-2) Positive control, avilamycin group (10mg/kg feed), T-3) Yeast extract-YCW (500 mg/kg), and T-4) Brewery-YCW (500 mg/kg feed). There were 6 replicates of 20 (experiment 1) and 22 (experiment 2) chicks per treatment. 3. In experiment 1 (wheat based diets), yeast extract-YCW increased BW and daily feed intake (42 d). The effects were comparable to those of avilamycin. In experiment 2 (maize based diet), avilamycin, yeast extract-YCW and brewery-YCW treatments improved the feed conversion ratio with respect to the negative control group (0 to 14 d). 4. At 24 d, in both experiments, the ileal nutrient digestibility and ileal bacterial counts were not affected by any experimental treatment. In maize diets, lower intestinal viscosity was obtained with avilamycin, yeast extract-YCW and brewery-YCW than with the negative control. In wheat diets, yeast extract-YCW and brewery-YCW reduced intestinal viscosity. 5. A third experiment was conducted to study the effect of yeast extract-YCW on animal performance, intestinal mucosa morphology and intestinal viscosity. A 2 × 2 factorial arrangement of treatments was used; one factor was the dietary yeast extract-YCW supplementation (0 or 500 mg/kg feed) and the other the cereal in the diet (maize or wheat). 6. At 43 d, the heaviest BW was in chickens fed on yeast extract-YCW compared to those given the negative control. At 22 d, yeast extract-YCW increased villus height, mucus thickness and number of goblet cells with respect to negative control. 7. Results of these experiments suggest that supplementation of yeast extract-YCW to broiler chicken diets increased animal performance by favouring intestinal mucosal development. © 2010 British Poultry Science Ltd.
