Shade for Cattle on Pasture: A Guide for Ontario Producers
In tropical climates, adequate shade may be essential to ensure the survival and productivity of grazing animals, but in the temperate Ontario climate, the necessity or benefits of providing shade for grazing cattle are less clear, and have proved controversial. Meteorological data indicate that beef cattle in Ontario may be at risk of suffering from heat stress on more than 25% of days during July and August, and may decrease feed intake and benefit from the provision of shade for more than 50% of days during the two hottest summer months. A booklet, entitled ‘Beat the Heat. A Guide to Hot Weather and Shade for Ontario Cattle Producers’, has been written for the Ontario Cattleman’s Association, as a means of providing basic information on heat biology in cattle, and as a focus for discussion on the value of shade to Ontario beef producers
Methods for assessment of keel bone damage in poultry
Keel bone damage (KBD) is a critical issue facing the laying hen industry today as a result of the likely pain leading to compromised welfare and the potential for reduced productivity. Recent reports suggest that damage, while highly variable and likely dependent on a host of factors, extends to all systems (including battery cages, furnished cages, and non-cage systems), genetic lines, and management styles. Despite the extent of the problem, the research community remains uncertain as to the causes and influencing factors of KBD. Although progress has been made investigating these factors, the overall effort is hindered by several issues related to the assessment of KBD, including quality and variation in the methods used between research groups. These issues prevent effective comparison of studies, as well as difficulties in identifying the presence of damage leading to poor accuracy and reliability. The current manuscript seeks to resolve these issues by offering precise definitions for types of KBD, reviewing methods for assessment, and providing recommendations that can improve the accuracy and reliability of those assessment
Effect of Piglet Age on Distress Associated with Gas Euthanasia, Neonate vs. Weaned
The objective of this study was to compare the effectiveness of euthanasia gases administered to 2 age groups of piglets: neonates (less than 3 days, n=160, BW 2.61 ± 0.81 kg) and weaned (16 to 24 days, n=160, BW 4.62 ± 0.76 kg). Two different gases were explored in this study: 100% CO2 and a 50:50 CO2:Argon (CA) gas mixture. Each gas was administered at 3 flow rates: 35%, 50% and Prefill + 20%, chamber volume exchange rate per minute. Latencies, durations and occurrence of behavior and physiologic changes were observed using direct observationand video. Neonate piglets were euthanized as quickly as or faster than weaned piglets for all gases and flow rates. For the neonate relative to the weaned piglet, average loss of posture over all gas treatments was 99 vs. 142 (seconds) and last movement was 360 vs. 392 (seconds). Neonates also displayed fewer incidences and shorter durations of behavioral indicators of distress and sensation relative to the weaned piglets. Thus concerns for gas euthanasia, when applied appropriately, are not greater for the neonate relative to the weaned piglet. Additionally, procedures developed to euthanize weaned piglets will likely be successful when applied for the neonate, but not viceversa
Comparativa de la situación de la mujer en la educación Española y Alemana
Treball Final de Grau en Mestre o Mestra d'Educació Infantil. Codi: MI1040. Curs acadèmic: 2016/2017Este trabajo tiene como objetivo principal conocer el papel de la mujer en la sociedad y cómo esto influye en la educación infantil, además de ofrecer una comparativa con otros países Europeos con una ideología conservadora similar a la de España, como pueden ser Alemania o Inglaterra, cuya religión mayoritaria no es el catolicismo.
Para conseguir nuestro objetivo hemos realizado un trabajo basado en la recogida de información de diversas fuentes, entre ellas, libros, artículos de revista, materiales digitales.
Esto nos ha ayudado a comprender que hay una gran diferencia de género entre los docentes de educación infantil a consecuencia de una larga tradición histórica que sigue perdurando hoy en día. Para comprender esto también se ha analizado el desarrollo histórico de la educación infantil a lo largo de la historia, centrándonos principalmente en dos países como hemos dicho anteriormente, España y Alemania.
Finalmente se presentan una serie de conclusiones donde se reúnen todas las informaciones encontradas y la síntesis a la que nosotros llegamos tras realizar el siguiente trabajo
Educación para la diversidad afectivo-sexual desde la perspectiva de las familias homoparentales
Treball final de Grau en Mestre o Mestra d'Educació Infantil. Codi: MI1040. Curs acadèmic 2016-2017Este proyecto tiene como objetivos conocer la opinión de algunas familias homoparentales acerca del trabajo de la diversidad afectivo sexual en las escuelas, acercarnos al trato que reciben algunas familias homoparentales en lasaulas y descubrir qué mejoras educativas proponen las familias homoparentales para fomentar la inclusión del colectivo LGBT en el ámbito escolar.
Para llevar a cabo este trabajo, en primer lugar, se ha realizado una primera aproximación a la materia a través de la búsqueda de autores y documentos que avalen la necesidad de trabajar este tipo de diversidad, cómo se trata este tema en el sistema educativo actual, así como la necesidad de introducir a las familias en las aulas.
Después, para averiguar de primera mano la visión de las familias homoparentales acerca de este tema, se han realizado entrevistas a tres familia de diferentes edades, procedentes de diferentes lugares y con diferente grado de participación en asociaciones LGBT. Para llevar a término estas entrevistas, se ha utilizado una metodología cualitativa, basada en una entrevista semiestructurada y preguntas abiertas. Estas preguntas están separadas en temas, todos relacionados con los objetivos propuestos (sistema educativo, relación familiar, relación con la escuela,…).
Para finalizar, a partir de las respuestas de las tres familias se ha realizado el análisis de datos. Este se ha llevado a cabo a través de la comparación y el contraste de las diferentes visiones de las familias. A raíz del análisis se han podido deducir las siguientes conclusiones: en las escuelas no se trabaja la diversidad afectivo-sexual o no se introduce en toda su complejidad, la educación para este tipo de diversidad podría solucionar el aumento de las agresiones homófobas, el colectivo LGTB continúa viviendo situaciones de desigualdad respecto a los heterosexuales y en el sistema educativo sigue vigente la heteronormatividad
Investigation Into the Humaneness of Slaughter Methods for Guinea Pigs (Cavia porcelus) in the Andean Region
Guinea pigs (Cavia porcelus) are an important source of nonhuman animal protein in the Andean region of South America. Specific guidelines regarding the welfare of guinea pigs before and during slaughter have yet to be developed. This study critically assessed the humaneness of 4 different stunning/slaughter methods for guinea pigs: cervical neck dislocation (n = 60), electrical head-only stunning (n = 83), carbon dioxide (CO(2)) stunning (n = 21), and penetrating captive bolt (n = 10). Following cervical neck dislocation, 97% of guinea pigs had at least 1 behavioral or cranial/spinal response. Six percent of guinea pigs were classified as mis-stunned after electrical stunning, and 1% were classified as mis-stunned after captive bolt. Increased respiratory effort was observed during CO(2) stunning. Apart from this finding, there were no other obvious behavioral responses that could be associated with suffering. Of the methods assessed, captive bolt was deemed the most humane, effective, and practical method of stunning guinea pigs. Cervical neck dislocation should not be recommended as a slaughter method for guinea pigs
