Development of online learning activities to enhance student knowledge of animal behaviour prior to engaging in live animal handling practical sessions  [PDF]
Julie M Old, Ricky-John Spencer
Open Journal of Animal Sciences (OJAS) , 2011, DOI: 10.4236/ojas.2011.12009
Abstract: Learning activities were developed to increase the awareness of animal behaviour among first year students enrolled in animal-associated degrees prior to students engaging in hands-on live animal practical sessions. Learning activities were developed in an easy to use collegial online environment and to encourage student engagement in learning activities. One hundred and one students were given a preliminary and post learning activity survey to assess their initial knowledge and experience of animal behaviour, as well as to determine if the learning activities increased the students’ knowledge of animal behaviour after engaging in the learning activities. Of the students surveyed, most currently owned pets or have had pets (91.1%), some had animal-related qualifications (22.8%) and currently worked in an animal-related position (24.8%). There was a significant difference (70.3% increase) in student responses after engaging in the learning activities with the major change occurring in the students’ understanding of the term ‘ethology’, regardless of the level of qualifications or animal-related career experience. In addition, after engaging in the learning activities, most students believed that they could better articulate and interpret animal behaviors based on their observations. Overall, the inclusion of learning activities successfully increased the ability of students to understand behavioral traits of animals, which will increase safety in live animal practical sessions. The learning activities also encouraged a collegial learning environment that enhanced new knowledge construction amongst the students.

Open Journal of Animal Sciences (OJAS) , 2012, DOI: 10.4236/ojas.2012.21008
Abstract: In Italy, Law no. 189/2004 (enforced by law n. 201/2010) on safeguarding animal welfare establishes penalties for anyone keeping animals in conditions that are incompatible with their physiological or ethological needs. Thus, in order to recognize the condition of poor welfare or mistreatment, the training of a veterinarian needs to adopt a new approach to animal well being —that is somewhat different from the health ideas that have been prevalent so far. In this research we carry out an evaluation of the competence of veterinary students after a theoric 20-hour course in ethology and after three weeks of practical horses handling class. For two years 24 students were selected to took part in a program of horse management, in order to reach a high level of practical competence, from the ability to recognize non-verbal signals from horses, to cleaning and grooming, and to a more specific and refined ability—the establishment of a relationship with horse. While the skill level at the beginning was generally low, being the students’ backgrounds mainly urban, at the end of the practical course nearly 90% of them succeeded in the area of horse-human relationship, reaching evaluations in a range of good-excellent scores (p < 0.01). By combining over the years the applied ethology knowledge with the more profession-oriented health-related subjects, veterinary education will give students the resources that can better assist them in facing the challenges they will meet in their working lives. The fact that too many unlawful horses’ estab-lishments are often found all over the countries point indeed to a need for new experienced, well-trained professional people.
Comparative study of the nesting behaviour of Tachysphex inconspicuus (Kirby) (Hymenoptera: Crabronidae) in two locations in southeast Brazil

Abstract: the nesting behaviour of the solitary wasp tachysphex inconspicuus (kirby) was comparatively studied based on observations made in two environmentally distinct locations in southeast brazil: upper portions of two sandy beaches and a dirt road in a forested area. motor patterns related to nest construction were similar in all observed wasps, but some behavioural features, which were different among the observed wasps in the two environments, seem to be constrained by ecological factors. t. inconspicuus can be behaviourally differentiated from several other species of the genus by the following combination of features: they close the nest temporarily during its provision, do not let the excavated sand to form into a mound in front of the nest entrance, construct unicellular nests, and provision the nest with cockroaches. moreover, females t. inscospicuus use their hind legs in a peculiar way to manipulate the prey, which allows them to associate the use of the mandibles in prey transport with the possibility of excavating the temporary plug and entering the nest without releasing the prey. chorisoneura lopesi albuquerque, c. excelsa albuquerque & silva, and unidentified species of riatia (blattodea: blatellidae) were found as prey and amobia floridensis (towsend) (diptera: sarcophagidae) as parasitoid of t. insconspicuus.

Abstract: animal welfare is an ethical element of the integral "meat quality" concept. consumers, besides demanding innocuous food, everyday demand food produced under ethical animal handling. the knowledge of bovine ethology, and cattle handling favoring their natural behavior, reduce the risks of the staff's occupational accidents, and prevent unnecessary suffering of animals. this article presents the management guidelines for the implementation of pre-slaughter practices based on cattle behavior as well as the importance of staff training and auditing.

Abstract: this study aimed to evaluate the effect of feed restriction on the ingestive behavior of guzerat and sindhi heifers. a total of 36 heifers were used, 18 from each breed, randomly distributed in a completely randomized design, in a 2 x 3 factorial scheme. the treatments used were 20 and 40% restriction compared to intake by animals from the third group, which were fed ad libitum (without restriction). for the behavioral analysis, the scan sampling method was used by logging and recording times in five-minute intervals during 24 hours, thus estimating the time spent feeding, ruminating and idling. with regard to the imposed restrictions, it was observed that non-restricted animals showed greater feeding time and lower resting time (p < 0.05); the two breeds showed the same feeding efficiency. when subjected to levels up to 40% of feed restriction, both studied genotypes perform similarly with regard to ingestive behavior, feeding efficiency and cud chews. however, there was an effect of the restriction levels on the patterns of ingestive behavior and cud chews, although there were no changes to feeding efficiency or chewing time per cud.
O que as ciências da etologia e da primatologia nos ensinam sobre as práticas científicas?
Despret, Vinciane;
Fractal : Revista de Psicologia , 2011, DOI: 10.1590/S1984-02922011000100005
Abstract: the article discusses known studies conducted with animals, as well as the version in which the results acquired are biased by researcher's subjectivity. following the reflections on the research practices, we can consider the animals good models to the investigation about human beings. they can teach a lot about ourselves, since we have not neglected the way to make them understand our questions and we should know which question, indeed, they answer.

Abstract: this study evaluated the effects of aversive and non-aversive management on behaviour of holstein cows for the following variables: reactivity (re), defecation (de), urination (mi), time spent in the milking parlour (tpo), duration of milking (tor), milk production (pl), chemical composition of milk and somatic cells counting (ccs). thirty two 60-96 months old holstein cows, raising under semi-extensive system were used and submitted to the following treatments, in complete randomized blocks: t1= aversive management and t2= non-aversive management. significant differences were found between managements for reactivity (p<0.0001), defecation (p= 0.0208) and urination (p= 0.0007). cows aversively managed were the most reactive and showed the highest occurrence of defecation in the milking parlour. however, cows submitted to aversive management showed the lowest occurrence of urination in the milking parlour. there was significant interaction (p<0.0001) for management and days, regarding to tpo and tor. for milk production there was significant interaction (p= 0.0062) between management and cow age. cows averaging 60 months of age, submitted to aversive management produced less milk than cows non-aversively managed (8.68 kg milk/day and 11.50 kg milk/day), respectively. no significant differences were found for milk components and somatic cells. the aversive management alters the behaviour of dairy cows in the milking parlour, affecting the animal well-being and reducing milk production of cows with an average age of 60 months.

Abstract: the few data on the marine shrimp litopenaeus vannamei (boone, 1931) behavior related to artificial food offer in feeding trays may result an inadequate feeding by the animal, increasing the cost/benefit relation in shrimp culture and its potential environmental impact. in order to provide tools for optimizing feeding management in shrimp farms, a behavioral study was developed, using 64 l. vannamei juveniles (7,57 ± 1,01 g). they were submitted to artificial photoperiods, half of them in reversed cycle, in order to register their behavior during light and dark phases. in established intervals, the following activities were registered before and after food exposition: exploration, swimming, feeding and inactivity (instantaneous sampling). swimming occurred mostly during the dark phase. feeding time was higher in the half hour following food offer, especially during light phase. food offering worked out in both phases as an inductor of substrate exploration, making the shrimp more active in all the intervals following its introduction.

Abstract: the objective of this trial was to study the behavior of lactating holstein cows grazing pasture containing elephantgrass (pennisetum purpureum schum.) and a mixture of black oat (avena strigosa schreb.) plus ryegrass (lolium multiflorum lam.). data from six early to mid lactating cows were collected every 10 minutes interval by two observers (from 6 p.m. to 6 a.m. and from 8 a.m. to 4 p.m.) at three grazing cycles: 06/17, 08/04, and 09/16 of 2004. the following variables were measured: elephantgrass grazing time, black oat plus ryegrass grazing time, total grazing time (sum of elephantgrass and oat plus ryegrass), rumination time, and idle time. initial herbage mass, chemical composition of ingested forage, and environmental conditions were also evaluated. cows spent more time grazing after each milking and decreased thereafter. diurnal grazing time was longer than nocturnal. black oat plus ryegrass grazing time was greatest when the percentage of leaf lamina was lowest in the elephantgrass. idle time decreased and rumination time increased during grazing cycles as a consequence of reduction in the proportion of leaf lamina and elevation on that of stems in the winter species (black oat plus ryegrass). elephantgrass was grazed at all three grazing cycles. availability of plant species with different growth cycles allowed animals to select a high quality forage diet.
