Se despejan las dudas sobre las ventajas que presenta el huerto escolar y cu??les son sus principales inconvenientes. A trav??s del huerto se fomenta la creatividad, toma de decisiones, actitud cr??tica y responsable, en temas como el consumismo, etc. Cualquiera de los ejercicios que vienen en el libro de texto se puede modificar y adaptar a contenidos del huerto.

Se presenta una actividad interdisciplinar del ??rea de Pl??stica y Lengua que gira en torno a la creaci??n de un personaje relacionado con la alimentaci??n: la Superberenjena. A trav??s de ella se trabaja la comida sana, haciendo incursiones en el comedor del centro, protagonizando obras teatrales representadas por el alumnado y otras aventuras de lo m??s did??cticas. Los resultados de esta experiencia son muy positivos, llegando a convertirse la Superberenjena en la mascota del centro.

Sixty-nine entire male pigs with different halothane genotype (homozygous halothane positive – nn-, n=36; and homozygous halothane negative – NN-, n=33) were fed with a supplementation of magnesium sulphate (Mg) and/or L-tryptophan (Trp) in the diet for 5 days before slaughter. Animals were housed individually and were submitted to stressful ante mortem conditions (mixed in the lorry according to treatments and transported 1h on rough roads). Individual feed intake was recorded during the 5-day treatment. At the abattoir, pig behaviour was assessed in the raceway to the stunning system and during the stunning period by exposure to CO2. Muscle pH, colour, water holding capacity, texture and cathepsin activities were determined to assess meat quality. The number of pigs with an individual feed intake lower than 2kg/day was significantly different among diets (P<0.05; Control: 8.7%; Mg&Trp: 43.5%; Trp: 17.4%) and they were considered to have inadequate supplement intake. During the ante mortem period, 15.2% of pigs included in the experiment died, and this percentage decreased to 8.7% in those pigs with a feed intake > 2kg/day, all of them from the stress-sensitive pigs (nn). In general, no differences were observed in the behaviour of pigs along the corridor leading to the stunning system and inside the CO2 stunning system. During the stunning procedure, Trp diet showed shorter periods of muscular excitation than control and Mg&Trp diets. The combination of a stressful ante mortem treatment and Mg&Trp supplementation led to carcasses with high incidence of severe skin lesions. Different meat quality results were found when considering all pigs or considering only those with adequate supplement intake. In this later case, Trp increased pH45 (6.15) vs Control diet (5.96) in the Longissimus thoracis (LT) muscle (P<0.05) and pH at 24h (Trp: 5.59 vs C: 5.47) led to a higher incidence of dark, firm and dry (DFD) traits in SM muscle (P<0.05). Genotype affected negatively all the meat quality traits. Seventy-five percent of LT and 60.0% of the SM muscles from nn pigs were classified as pale, soft and exudative (PSE), while none of the NN pigs showed these traits (P<0.0001). No significant differences were found between genotypes on the incidence of DFD meat. Due to the negative effects observed in the Mg&Trp group in feed intake and carcass quality, the utilization of a mixture of magnesium sulphate and tryptophan is not recommended

Sixty-one animals with different Halothane genes (homozygous halothane positive, n=34; and homozygous halothane negative, n=27) were fed with three diets (controlgroup, with no supplement; magnesium (Mg) group with 1.28g MgCO3/kg and tryptophan (Trp) group with 5g L-Trp/kg) during the last 5 days before slaughter. Animals were submitted to minimal stress ante mortem conditions. Pig behaviour was recorded at the experimental farm, raceway to the CO2 stunning system and during the stunning period. Corneal reflexes were recorded after stunning as well. There were no differences in feed intake among diets (p>0.05) during the 5 days of treatment. The halothane positive (nn) group had lower intake than the halothane negative (NN) group (p<0.01). The behaviour of the pigs in the raceway did not differ (p>0.05) among treatments or halothane genotype. A significant (p<0.001) interaction diet*halothane was found in the time to appear the first retreat attempt during the exposure to the CO2 system. In the nn group, the time of performing the first retreat attempt was later in the Mg (p<0.05) than the Control group. Moreover, in the Mg group, the nn had a later (p<0.05) first retreat attempt than the NN. Thus, Mg supplementation could have a positive effect on welfare of nn pigs. The nn had a lower proportion of animals that showed corneal reflexes after stunning than NN, indicating a higher effectiveness of the stunning method in nn pigs. Neither Mg nor Trp affected carcass quality and meat quality parameters, although significant differences were found between genotypes

Esta comunicación versa sobre una experiencia educativa con estudiantes de una materia impartida en el segundo curso del Grado en Nutrición Humana y Dietética de la Universitat de València. La experiencia consiste en una serie de seminarios cuya finalidad es doble: por un lado, se pretende que el estudiante adquiera algunas competencias y habilidades propias de la investigación social aplicada a la salud y, por otro lado, se quieren potenciar competencias de exposición oral y expresión escrita de carácter científico, transversales al título. La metodología docente de los seminarios se ha planteado en la línea de reforzar el trabajo en equipo, el aprendizaje cooperativo y la implicación de los estudiantes en todo el proceso de aprendizaje. Esta comunicación explica las ventajas e inconvenientes de esta experiencia
