E-mail: aemurakami@uem.br An experiment was carried out to evaluate the effect increasing levels of yeast wall and broiler breeders’ age levels on lymphoid organs weight, cellular immune response and hematological parameters in broilers. A total of 3,360 Cobb broilers were allotted, in a completely randomized design and a 2x5 factorial arrangement, and two controls, compound of two broiler breeders age (34 and 57 weeks of age) and five yeast wall levels (zero, one, two, three and four kg of yeast wall/ton of diet). Broiler breeders’ age affected all studied variables. The inclusion of 3kg of yeast wall/ton of meal increased, at 57 weeks age broiler breeders, more intense inflammatory reaction when compared to control diet; however the circulated heterophils and lymphocytes numbers were not increased. In conclusion, the use of yeast wall, associated or not to sorghum on broilers diet still needs complementary studies, for example, purified components of yeast wall (MOS and ß-glucano).

Foram utilizados 3.360 pintos de corte da linhagem Cobb, distribuídos em delineamento inteiramente casualisado, em esquema fatorial 2x5, mais dois controles, sendo duas idades de matrizes (34 e 57 semanas de idade) e cinco níveis de suplementação de parede de levedura (zero, um, dois, três e quatro kg de parede de levedura/tonelada de ração). A idade das matrizes influenciou a resposta de todas as variáveis. A inclusão de 3kg de parede de levedura/tonelada de ração promoveu, na progênie de reprodutoras de 57 semanas, reação inflamatória mais intensa quando comparada a dieta controle, no entanto não houve aumento significativo no número de heterófilos e linfócitos circulantes. Conclui-se que a utilização da parede de levedura associada ao sorgo ou não em rações de frangos de corte ainda necessita de estudos complementares, que incluam, por exemplo, os componentes purificados da parede de levedura (MOS e ß-glucano).

E-mail: everton_unesp@yahoo.com.br Attempting to avoid difficulties associated to triple pelvic osteotomy (TPO), the sacroiliac wedge method was experimentally developed to increase the acetabular ventroversion. The goal of this study was to apply the techniques of sacroiliac wedge and TPO to canine cadavers and radiographically evaluate the efficacy of acetabular ventroversion. Ten cadavers of adult dogs weighting 15-25 kg were used. To each right hemipelvis the technique of TPO with 20° and 40° plates was applied. In the left hemipelvis, 20° and 40º wedges in the sacroiliac joint were applied. Radiographic evaluations in standard projections were carried out for measurement of the acetabular covering of the head of the femur in the two techniques. There was no significant differences between TPO and the use of sacroiliac wedge using implants of 20° and 40°, however a significant difference (p<0,05) could be observed before and after application of the 20° and 40° implants, as well as between those that received 20° and of 40° implants. The application of sacroiliac wedge produced similar results of those observed in TPO, and it is more feasible.

E-mail: everton_unesp@yahoo.com.br Na tentativa de evitar algumas das dificuldades associadas à osteotomia pélvica tripla (OPT), foi desenvolvido experimentalmente o método de aplicação de cunha na junção sacroilíaca para aumentar a ventroversão acetabular. O objetivo deste estudo foi aplicar as técnicas de cunha sacroilíaca e OPT em cadáveres e avaliar radiograficamente a eficácia da ventroversão acetabular. Para tal, foram utilizados 10 cadáveres de cães, adultos, com 15-25 kg. Em cada hemipelve direita foi realizada OPT com placas de 20° e 40°. Na hemipelve esquerda foram aplicadas cunhas nas articulações sacroilíacas de 20° e 40°. Avaliações radiográficas em projeções ventrodorsais foram realizadas para mensuração da cobertura acetabular à cabeça femoral nas duas técnicas. De acordo com os dados obtidos pode-se observar que não houve diferença entre a técnica de OPT e o uso de cunha sacroilíaca utilizando implantes de 20° e 40°, mas ocorreu diferença significativa (p<0,05) entre os cães antes e após a aplicação dos implantes de 20° e 40°, e também entre os que receberam implantes de 20° e os de 40°. A aplicação de cunha sacroilíaca produziu resultados semelhantes à OPT, e também se mostrou como de mais fácil aplicação.

In order to obtain additional reference values of left ventricular diastolic parameters and investigate influence of common variables, peak E wave (peak E), peak A wave (peak A), E/A ratio (E/A), E wave deceleration time (EDT) and isovolumic relaxation time (IRVT) were studied in 40 clinically healthy dogs, by pulsed wave Doppler. The following values were obtained: peak E = 0.747 ± 0.117 m/s, peak A = 0.487 ± 0.062 m/s, E/A = 1.533 ± 0.198, EDT = 88.7 ± 9.2 ms and IRVT = 0.080 ± 0.009 s. Some parameters were influenced by heart rate (peak E, peak A and IRVT), by age (peak A and E/A) and by body weight (TRIV). Gender influence was absent. Values obtained can be used as reference for canine specimens but its interpretation should consider on the influence of related variables.

However, circulatory arrest, event occasioned by this technique, may produce serious metabolic and neurological consequences to the patient. In this study, 12 mongrel dogs were used, divided into two groups, A and B, which were submitted to 7 and 8 minutes of total circulatory arrest, respectively, using “Inflow Occlusion” technique. Normothermia was tried during surgical procedures. Clinical and behavior evaluation were performed after surgery to both groups, and biochemical data were collected to compare pre and post-operatory moments. There were two transoperatory deaths in Group B. Transitory clinical problems were observed in group A until moment M7 (48 hours after surgery), and in Group B these problems were more intense and seen even after M7; and permanent blindness in one animal of Group B was present during all follow up period. Despite all alterations found during the study, it might be safe to use “Inflow Occlusion” technique for periods up to 7 minutes, however, it is contra-indicated for longer periods.

E-mail: benito.blanco@pq.cnpq.br The aim of this study was to determine whether goats could be averted from consuming Mascagnia rigida, a toxic plant found in the semiarid region of northeastern Brazil. Fourteen male goats not previously familiarized to M. rigida were randomly allocated to two treatment groups: control (treated with 5.5mL water orally by a drenching gun) and lithium group (treated with 100mg LiCl/kg body weight orally by a drenching gun). For conditioning, goats were allowed to feed on M. rigida leaves for 15 min, followed by LiCl or water administration. The time spent on eating M. rigida leaves was measured. The conditioning was repeated daily until the LiCl-treated goats stopped eating M. rigida. On the 10th, 17th, and 24th day after conditioning, extinction trials of the M. rigida aversion were performed in goats by using single-choice tests. There was no difference between the two treatment groups with respect to the consumption of M. rigida on the first day of aversion conditioning, however, controls ingested increasing amounts of the plant on consecutive conditioning days. On the second day, five out of the seven goats in the lithium group did not eat the leaves, but on the third day, all the goats in the lithium group did not ingest M. rigida. This aversion persisted throughout all evaluated days. This indicates that goats can be easily conditioned by using lithium chloride to avoid eating M. rigida temporarily

Serum was obtained from 923 animals of both sex, over three months of age from 17 properties in different cities. For the diagnosis, the indirect immunofluorescence reaction (RIFIe”16) and a questionnaire about health to collect epidemiological information and the reproductive cycle of every goat were used. Among all properties, 15 foci of T. gondii were diagnosed with seropositivity ranging from 2.70% to 81.25%. Neither association between the frequency of seropositivity and the sex of animals nor occurrence of reproduction failure of goats was identified. There was positive influence of anti-T. gondii antibody rate due to the older age of the animals and the presence of cats in pens. The risk of transmitting T. gondii to the public health must be considered, once in some properties where the positive serology was verified natural, products such as milk and/or meat are commercialized. Results were discussed at 5% level of significance.

E-mail: santin@ufpr.br From 253 wild birds attended at the Wild Animal Ambulatory of the Veterinary Hospital, Paraná Federal University, between August 2003 and August 2006, 45 cases (17.8%) were related to the species Serinus canarius (Belgian Canary). Within these attended birds and its respective orders, most morbid conditions occurred with the Psittaciforme order and were caused by traumatism, in 45 cases (14.32%). Of these, 17 animals (30.91%) had bone fractures; the most common were on radius-ulna (17.65%). Other conditions were presence of ectoparasites (12.50%) and endoparasites (10.68%), respiratory disease (10.42%), dermatological ailments (6.51%), neoplasms (4.95%), ophthalmic illnesses (4.43%), gastrointestinal diseases (3.91%), cachexia (3.39%), neurological diseases (2.86%), self-mutilation (2.86%), obesity (2.34%), aggression by other animals (1.56%), nutritional deficiencies (1.30%), egg retention (1.04%), avian poxvirus (0.78%) and uric gout (0.52%), as well as there was clinical routine measures to be taken (7.55%). Traumas and illnesses were observed as the highest prevalence on the casuistic, which could be prevented by correct husbandry practices.

E-mail: rfecchio@gmail.com Traction effort was applied perpendicularly to the axis of toucan beaks and for accomplishment of the essay a dynamometer was used. The beak was completely fractured when submitted to traction of 270.40 N. For fixation of the fractured beaks acrylic resin was applied using a strip of 2.0cm of width. The second beak presented resistance up to 69.75 N. The third beak was submitted to acid conditioning and resisted to force of 63.29 N. Other two new tests were accomplished the whole surface of the rhinotheca filled out. The fourth beak was not submitted to the acid attack and it resisted up to 134.40 N, and the fifth was submitted to the acid etch and it resisted up to 101.50 N. The present work did not observe statistical correlation and, consequently, differences among the procedures with previous use of acid attack and those without the use of the same.
