How Does the Addition of Gel at the Time of Vaccination Affect Overall Nursery Pig Performance?

Swine industry feed suppliers are continually striving to create techniques and tools to reduce the additive stressors imposed on the weanling piglet, to increase advantageous behaviors (feeding and drinking) and to reduce aggrieve interactions. In addition to social reorganization, pigs are often vaccinated during the nursery phase to reduce the impact of potentially harmful diseases. It has been noted by swine practitioners that at the time of vaccination many pigs lie down, rest more and reduce the amount of feed consumption over the vaccination period. One product on the market is a gel-based feed that is designed to ease the transition from a liquid diet (sow\u27s milk) to dry ration. This gel-based feed contains high quality ingredients; it is highly palatable and provides the young pig with both a feed component and a water component thereby influencing feed consumption and intestinal health. The gel can be used in addition to a standard weaned pig solid ration. Although, often recommended to be used at the time of weaning, the possibilities of implementing the gel around the time of vaccination is a novel concept that might impact the individual pig’s overall performance. The objectives of this study were to determine if the addition of gel at the time of vaccination provided benefits to the nursery pigs’ performance

Differences in Nursery Pigs’ Behavior on the Day of Vaccination

Swine industry feed suppliers are continually striving to develop techniques and tools to reduce the additive stressors imposed on the weanling piglet, to increase advantageous behaviors (feeding and drinking) and to reduce aggressive interactions. One product on the market designed to ease the transition from a liquid diet (sow\u27s milk) to a dry ration is a gel-based feed supplement that was incorporated in this trial as a means to positively affect feeding and drinking behaviors. The objectives of this study were to determine if there were differences in the nursery pigs’ behavior on the day of vaccination when provided a gel supplement. A total of 29 d crossbred pigs (5.94 kg) were housed in Double L® confinement nursery buildings. Four treatments were compared. No vaccine and no gel (control n = 4) defined as unvaccinated and without supplemental gel at days 8 to 10. No vaccine and gel (n = 4) defined as pigs that were provided supplemental gel at days 8 to 10 without vaccination. Vaccinated and no gel (n = 4) defined as pigs that were vaccinated but did not receive supplemental gel at days 8 to 10. Vaccinated and gel (n = 4) defined as pigs that were provided supplemental gel at days 8 to 10 and were vaccinated. The group of four pigs housed together in a pen was considered the experimental unit for data analysis. Definitions for the behaviors and postures recorded and summarized for the trial included the following: Active was defined as standing, this included any upright postures. Inactive posture was defined as sitting or lying postures (both lateral and sternal). Time at drinker was defined as when an individual pig’s mouth was around the water nipple. Time at feeding stations was defined as the time when the individual pig’s head was inside the creep (that contained gel) or the three hole feeder (dry pelleted feed). Nursery aged pigs were less active (P \u3c 0.05; Figure 1) and spent less time (P \u3c 0.05; Figure 2) at the feeding stations 1- h after receiving Mycoplasma hyopneumoniae vaccination, indicating a short term behavioral response to this stressor. These behavioral alterations continued for approximately 6- h (or 5:00 PM the vaccination day afternoon). After this time, all nursery pigs regardless of treatment engaged in the same behavioral repertoire. However, the behavioral repertoire of these nursery pigs were not different over the 3-d trial (previously published worked by Johnson et al., 2008) suggesting that the effects of this vaccination stressor and product were not long lasting

The Effect of Supplementing Dry Feed with a Nutritional Gel Product at the Time of Vaccination on Nursery Pig Maintenance Behaviors and Postures

Swine industry feed suppliers are continually striving to develop techniques and tools to reduce the additive stressors imposed on the weanling piglet, to increase advantageous behaviors (feeding and drinking) and to reduce aggressive interactions. One product on the market designed to ease the transition from a liquid diet (sow\u27s milk) to a dry ration is a gel-based feed supplement that was incorporated in this trial as a means to positively affect the aforementioned parameters. The trial was conducted in the spring of 2007. A total of 64 3-week old, crossbred pigs (4.2 kg) were received from a commercial farm and housed in Double L ® confinement nursery buildings. Four treatments were compared. Control groups (n = 4) were defined as unvaccinated and without supplemental gel at days 9 to 11. Treatment one (TRT 1 n = 4 groups) was provided supplemental gel at days 9 to 11 without vaccination. Treatment two (TRT 2; n = 4 groups) was vaccinated but did not receive supplemental gel at days 9 to 11. Treatment three (TRT 3; n = 4 groups) received supplemental gel at days 9 to 11 and were vaccinated. The group of four pigs housed together in a pen was considered the experimental unit for data analysis. Definitions for the behaviors and postures recorded and summarized for the trial included the following: Active was defined as standing, this included any upright postures. Inactive posture was defined as sitting or lying postures (both lateral and sternal). Time at drinker was defined as when an individual pig’s mouth was around the water nipple. Time at feeding stations was defined as the time when the individual pig’s head was inside the creep (that contained gel) or the three hole feeder (dry pelleted feed). There were no differences between treatments for active (P = 0.60), inactive (P = 0.99) or time at drinker (P = 0.37), respectively. There was a difference (P = 0.0085) between treatments for the percentage of time spent at the feeding stations with pigs receiving vaccine and no gel spending the least amount of time at the feeding stations compared to the other three treatment groups. Therefore, the availability of a gel product when pigs are vaccinated provided some benefit, as the time spent at the feeding station was higher compared to pigs that did not have access to the gel

Pedagogías emergentes : Repensando la educación desde las tic, la virtualidad y la ruralidad

Este libro es una apuesta de docentes, egresados y estudiantes de la Licenciatura en Comunicación e Informática Educativa de la Universidad Tecnológica de Pereira que, comprometidos con la formación integral del ser humano, cuestionan su papel como creadores de cuestionamientos y hacedores de respuestas contextualizadas y abordadas no solamente desde la Universidad, sino también desde el análisis y requerimientos del entorno. Así, a modo de recopilación de experiencias y reflexiones educativas que se agrupan en capítulos según afinidades temáticas, estos jóvenes docentes, egresados y estudiantes intentan develar la significación del proceso de la enseñanza y el aprendizaje desde lo crítico y lo complejo; como también desde el cuestionamiento sobre los retos y la responsabilidad social.

Discovery of Ophiostoma tsotsi on Eucalyptus wood chips in China

Ophiostoma species such as O. quercus are the most frequent causal agents of sapstain of freshly felled hardwood timber and pulpwood. Many species are regarded as economically important agents of wood degradation. The aim of this study was to identify a collection of Ophiostoma isolates, resembling O. quercus, found on stained Eucalyptus pulpwood chips in China. DNA sequences of the internal transcribed spacer regions, including the 5.8S region, of the ribosomal DNA, and parts of the β-tubulin and elongation factor-1α genes, revealed that the isolates were not O. quercus. Surprisingly, they represented O. tsotsi, a wound-infesting fungus recently described from hardwoods in Africa. In addition, sequence data from an isolate from agarwood in Vietnam, identified in a previous study as belonging to an unknown Pesotum species, were also shown to represent O. tsotsi. A high level of genetic variability was observed among isolates of both O. quercus and O. tsotsi. This was unexpected and suggests that both species have been present in Asia for a significant amount of time.National Research Foundation (NRF), South Africa; members of the Tree Protection Co-operative Programme (TPCP), South Africa; THRIP initiative of the Department of Trade and Industry (DTI), South Africa; Department of Science and Technology (DST), South Africa; Ministry of Science and Technology of China (MOST
