Avaluació de l’esforç submàxim dels flexors dorsals i palmars de canell mitjançant dinamometria isocinètica

El SEC (Suma Excèntric- Concèntric) i sobretot el DEC (Diferència Excèntric-Concèntric) són paràmetres que, ja han sigut demostrats en la literatura, com a vàlids en diferents articulacions i accions, per a identificar esforços submàxims, és a dir, la possible falta de col•laboració, durant la realització de proves de força mitjançant dinamometria isocinètica. Aquest estudi, mitjançant una mostra de 20 individus sans, demostra que el DEC i el SEC són bones eines per detectar la falta de col•laboració en l’avaluació dels flexors dorsals i palmars de canell (articulació prèviament no estudiada) amb dinamometria isocinètica en subjectes sans.

Effect of vaccination against gonadotrophin-releasing hormone, using Improvac®, on growth performance, body composition, behaviour and acute phase proteins

The objective of this study was to evaluate the effect of vaccination against GnRH on performance traits, pig behaviour and acute phase proteins. A total of 120 pigs (36 non-castrated males, NCM; 36 males to be vaccinated, IM; 24 castratedmales, CM; and 24 females, FE)were controlled in groups of 12 in pens with feeding stations allowing the recording of individual feed intake. The two vaccinations (Improvac®) were applied at a mean age of 77 and 146 days. All pigswere individually weighed every 3 weeks from the mean ages of 74 to 176 days and backfat thickness (BT) and loinmuscle depth (LD) were also recorded ultrasonically. Twelve group-housed pigs for each treatment were video recorded during 2 consecutive days at weeks 9, 11, 20, 21, 23 and 25 of age to score the number of inactive or active pigs in each treatment group by scan sampling. Aggressive behaviour by the feeder and away from the feeder, and mounting behaviour was also scored by focal sampling. Blood samples from 12 NCM, 12 CM and 12 IM were taken to determine the concentration of circulating acute phase protein Pig-MAP atweeks 1, 2, 4, 11, 13, 21 and 25 of age. After slaughter, the number of skin lesions on the left half carcasswas scored. IMpresented overall a higher growth rate and daily feed intake compared to NCM (Pb0.05),whereas their feed conversion ratios did not differ significantly. In comparison with CM, IM presented a better feed conversion ratio (Pb0.05), since their overall dailyweight gaindid not differ significantly, butIM ate less. Final leanmeat percentage of IM and CM was lower compared to that of NCM (Pb0.05). Activity, mounting and aggressive behaviour of NCM was higher than in IM, CM and FE after the second vaccination. Pig-MAP concentrationswere significantly elevated just after surgical castrationand after bothadministrations of the vaccine (Pb0.05), but concentrations subsequently decreased throughout time. Skin lesions of NCM were significantly higher compared to that of IM and FE (Pb0.05). The effects of vaccination were especially remarkable after the second dose, when the higher feed intake and lower activity of IM compared to NCMmight result in higher final body weight and more fat. Results from this study indicate that some welfare aspects such as a reduced aggression and mounting behaviour may be improved by vaccination against GnRH, together with productive benefits like adequate feed conversion ratio and daily weight gain.

Application of ZnO-Functionalised-Sepiolite in weaning piglet diets

The objective was to evaluate the effect of ZnO-Functionalised-Sepiolite (ZnO-Sepiolite) to fulfil Zn requirements and health status of weaning piglets. Pre-starter Basal Diet (BD, corn– soybean based, from weaning till 14 days on trial) was calculated to provide 27 mg Zn/kg feed from raw materials and had no added ZnO and no antibiotics or organic acids. Treatments during pre-starter period were: 1) BD+90% of NRC Zn requirements completed with ZnO (ZnO90); 2) BD+90% of NRC Zn requirements completed with ZnO-Sepiolite (ZnOS90); 3) BD+3000 mg ZnO/kg of diet (ZnO3000); 4) BD+150 mg added Zn/kg diet from ZnO-Sepiolite (ZnOS150). The starter feed (corn–soybean based, from 14 till 31 days on trial) was common for all piglets, and met 90% NRC Zn requirements by adding ZnO. Diarrhea affected more than 50% of the animals of ZnO90, ZnOS90 and ZnOS150, and 33% of the ZnO3000 animals. Animals from ZnOS90 tended (Pb0.10) to improve Gain to Feed ratio (G:F) compared to animals from ZnO90 (0.830 kg/kg vs. 0.811 kg/kg for G:F). Performance of animals from ZnO3000 was not significantly different from the other treatments, and was numerically similar to animals from ZnOS90. The inclusion of ZnO at 3000 mg/kg of feed in the pre-starter period numerically decreased P in serum at the end of this period, with no effect on Ca level; normal levels were restored after 2 weeks of feeding the same levels of Zn than other animals. Animals fed ZnOSepiolite diets had numerically higher serum Ca than ZnO90 and ZnO3000 at 12 days and higher than ZnO90 at 28 days. Serum Zn levels were significantly higher for ZnO3000 than the other treatments.

Strategies of use of a specific immunoglobulin-rich egg yolk powder in weaning piglets

Two experiments were performed to determine the best strategy of use of the product TRACTcare® 4P (ITPSA) (TC, specific immunoglobulin-rich egg yolk powder within an energetic fatty acid matrix) in piglets from weaning and for 6 weeks, in diets without or with inclusion of antibiotics. Each trial was performed with 144 piglets in 24 pens, in a completely randomized design blocked by initial body weight. Feeds were formulated according to animal requirements in two periods. In the first trial no antibiotics were included in the feeds and no room disinfection from previous trial was performed; treatments were: 1) Negative control (NC); 2) NC+TC on top of the feed within the hopper for the first 3 days on trial (30 g/pig×day), and eventually if diarrhea appeared (TCOT); 3) NC+TC ad libitum provided in an extra hopper within the pen (TCAL); and 4) NC+TC at 5 g/kg added to the feed in the mixer (TC5). In the second trial, treatments were: 1) Positive control: basal diet that included 250 mg/kg amoxiciline (BD)+100 mg/kg colistine (AC); 2) BD+2 g/kg TC (TC2A); 3) BD+5 g/kg TC (TC5A); and 4) BD+8 g/kg TC (TC8A). In diets without antibiotics, the product TC at 5 g/kg in the feed numerically improved BW by 8% compared to Control animals, while G:F was almost identical between both groups. When antibiotics were used in the feed, replacement of colistin at 100 mg/kg for TC at 2 g/kg in feed numerically improved the performance compared to Positive control animals (for the whole trial period ADG 8% better: 390 g vs. 361 g; G:F 1% better: 0.748 kg/kg vs. 0.742 kg/kg), possibly due to the stimulation of feed consumption at weaning. In both trials, the lower number of dead and culled animals from TC5 and TC2A together with higher BW represented an advantage over Control treatments of 6% to 10% animals more and 15% to 17% total BW more at the end of the trial.

Probiotic microorganisms: 100 years of innovation and efficacy. Modes of action

AbstractArticle StructureFigures and TablesReferences Benefits from probiotic micro-organisms have been recognised for over 100 years, and as being useful in poultry for 50 years. Fuller (1989) redefined probiotics as ‘a live microbial feed supplement which beneficially affects the host animal by improving its intestinal microbial balance’. Benefits derived from this improved intestinal microbial balance could be reflected in performance or prevention of pathogen colonisation. Probiotic micro-organisms use in poultry production has been widely accepted and new opportunities arose from the 2006 EU ban on antimicrobial growth promoters. The majority of microbial products for compound feeds are made up from a relatively small number of micro-organisms that are normally present in the GI tract. They include non-sporulated bacteria, sporulated bacteria, fungi or yeasts; and presented from single to multi-strain products. A review on the proposed modes of action is presented including recent approaches to quorum sensing interference

Patacades, parenostres i sardanes : documentació i anàlisi de la festa de Sant Sebastià de Cadaquès

El tema en què se situa aquest projecte és el de “música i Festa”. El cas documentat i analitzat és el de la festa de Sant Sebastià de Cadaqués (Catalunya) que es celebra el 20 de gener, principalment a l’ermita situada a la muntanya del Pení. Se n’estudien els tres elements musicals principals relacionant-los amb el tot de la festa: la missa, les sardanes i les patacades, un ball en el qual es canten sàtires. L’objectiu principal del projecte és veure si, per com es realitzen i es conceben la música i el ball, l’esdeveniment té més característiques de la Festa, entenent aquesta com un camp d’estudi divers.

On Lundh's percolation diffusion

A collection of spherical obstacles in the unit ball in Euclidean space is said to be avoidable for Brownian motion if there is a positive probability that Brownian motion diffusing from some point in the ball will avoid all the obstacles and reach the boundary of the ball. The centres of the spherical obstacles are generated according to a Poisson point process while the radius of an obstacle is a deterministic function. If avoidable con gurations are generated with positive probability Lundh calls this percolation di usion. An integral condition for percolation di ffusion is derived in terms of the intensity of the point process and the function that determines the radii of the obstacles.

Sistemes de crèdit hipotecari en l'europa del segle XIX, en especial a Catalunya i Espanya: legislació hipotecària i bancs hipotecaris

Investigación producida a partir de una estancia en la Westfälische Wilhelms-Universität, Alemania, entre julio y septiembre del 2007. En este trabajo, se estudia la situación del crédito hipotecario en España a mediados de siglo XIX (con especial atención a Cataluña). En su desarrollo, se abordan tres cuestiones. La situación del crédito hipotecario en España a mediados de siglo XIX. La legislación hipotecaria española en el siglo XIX. En especial, se ha puesto de relieve su incapacidad para movilizar la riqueza inmueble, que sólo se solucionó con una completa reforma hipotecaria y registral. El “sistema de crédito territorial” que, ideado por el desconocido abogado catalán Joaquín Borrell y Vilá, debe considerarse como el verdadero primer paso jurídico hacia el futuro desarrollo de las instituciones de crédito hipotecario en España, aunque fue ignorado por el Gobierno y los agentes económicos.

Una revisió del sistema de seguretat pública de Catalunya a partir de l'estudi de la demarcació de Girona

En aquest sentit, no hem d’oblidar que l’èxit o el fracàs en la selecció d’un model de prestació de serveis de seguretat avançat depèn, de manera principal, de en quina mida serem capaços d’adaptar-nos als requeriments actuals i d’anticipar-nos a la demanda futura. No tinc cap dubte que és precisament aquí on està una part de la clau de l’èxit o el fracàs de les polítiques públiques de seguretat: en l’establiment d’una sintonia fina entre els productors de serveis seguretat -i aquí entra també la seguretat privada, a més de la pública- i els receptors d’aquests serveis –la ciutadania, entesa com a ciutadans i com a entitats ciutadanes. Per a trobar l’altra part de la clau cal donar un pas més: entendre que els ciutadans i les seves entitats són –a més de receptors- productors de seguretat, d’aquí la importància capital de la qüestió de la participació ciutadana.
