The objective of this work was to evaluate the quantitative and qualitative characteristics of carcass and meat of Dorper x Santa Ines crossbred lambs finished in a silvopastoral system, pasture or feedlot. Twenty-four non-castrated male lambs were used (8 animals in each production system). The experimental design was completely randomized, with three production systems and eight replications. The production systems were: pasture of Megathyrsus maximus cv. Aruana, without shading + feed supplementation (Pasture); pasture of Megathyrsus maximus cv. Aruana, with natural shading provided by the native laurel tree (Cordia trichotoma) + feed supplementation (Silvopastoral) and feedlot. The cold carcass weight, empty body weight, cold carcass yield, fat color, fat consistency and carcass compactness index showed significant differences (P < 0.05) between production systems, with higher values observed in the feedlot. The shoulder weight and the percentage of shoulder components (bones, muscle, fat and others), did not significantly differ (P > 0.05) between production systems. The pasture silvopastoral systems presented similar results and also, when contrasted with the feedlot system, did not influence the parameters related to meat. Feedlot provided better quantitative and qualitative characteristics to the lambs’ carcassess. O objetivo deste trabalho foi avaliar as características quantitativas e qualitativas da carcaça e da carne de cordeiros mestiços Dorper x Santa Inês terminados em sistema silvipastoril, a pasto e confinamento. Foram utilizados 24 cordeiros machos não castrados (8 animais em cada tratamento). O delineamento experimental foi inteiramente casualizado com três tratamentos e oito repetições. Os tratamentos foram: pastagem de Megathyrsus maximus cv. Aruana, sem sombreamento + suplementação alimentar (Pastagem); pastagem de Megathyrsus maximus cv. Aruana, com sombreamento natural proporcionado pela espécie arbórea Louro-Pardo Nativo (Cordia trichotoma) + suplementação alimentar (Sivilpastoril) e confinamento em aprisco. O peso de carcaça fria, peso de corpo vazio, rendimento de carcaça fria, cor da gordura, consistência da gordura e índice de compacidade da carcaça apresentaram diferença significativa entre os tratamentos (P < 0.05), com valores superiores observados no confinamento. O peso das paletas e a porcentagem dos componentes da paleta (ossos, músculo, gordura e outros), não diferiram significativamente (P > 0.05) entre os sistemas de produção. Os sistemas a pasto sem sombreamento e silvipastoril apresentaram resultados similares, e quando contrastados ao confinamento não apresentaram influência nos parâmetros relacionados a carne. O confinamento proporcionou melhores características quantitativas e qualitativas às carcaças dos cordeiros.

A osteotécnica é uma ferramenta de ensino em anatomia e zoologia para a fixação didática de conteúdos e que pode promover a conscientização ambiental, além de a preparação das peças proporcionar o contato com diferentes espécies permitindo ao acadêmico expandir seu conhecimento e desenvoltura no trabalho em equipe. O objetivo do trabalho foi preparar peças anatômicas para o desenvolvimento técnico e cientifico dos acadêmicos, além de servir como material didático e de auxílio na conscientização ambiental. Os animais preparados foram provenientes de atropelamentos e doações do Zoológico de Cascavel, o trabalho foi desenvolvido no Laboratório de Zoologia da Universidade Tecnológica Federal do Paraná (UTFPR), Campus Dois Vizinhos. Os animais preparados por meio da osteotécnica foram macaco-prego (Sapajus apela - Illiger, 1815), gavião carcará (Caracara plancus - Miller, 1777) e uma coruja suindara (Tyto furcata - Temminck, 1827). Os espécimes foram acrescentados ao acervo do Laboratório de Zoologia da UTFPR-DV, proporcionando aos alunos e público em geral a oportunidade de conhecer a anatomia de diferentes espécies animais.

This research aimed to evaluate the effect of 5% aqueous extracts of marjoram (Origanum majorana L.) and pomegranate (Punica granatum L.) on Cobb chicken (Gallus gallus domesticus L.), as a model to birds as non-target organisms for pest control. The extracts were prepared using dried ground leaves. The powder obtained was then added to distilled water to obtain 5% extract (w/v). After 48 h, the plant extracts were filtered and added to the feed of 36 female birds. For that, the chicken (12 days old) were acclimated for 3 days before starting the experiment. The plant extracts were administered for 6 days, always preceded by at least 14-h starvation. The birds were evaluated for 11 days, assessing behaviour, feed consumption and animal performance. After sacrificing the birds, histopathological examination was performed, and intestinal villi were measured. No death nor any alteration occurred during the experiment. There was no statistical difference among the treatments regarding feed consumption and performance even though there was intestinal villi reduction.

Extracts of Matricaria chamomilla, Maytenus ilicifolia and Echinodorus grandiflorus have been integrated as viable pest management strategy for controlling bronze bug Thaumastocoris peregrinus (Hemipetra: Thaumastocoridae) due to their insecticidal activities. However, the side effects of these extracts on Cleruchoides noackae (Hymenoptera: Mymaridae), the main biological control agent against the bronze bug of eucalyptus, have never been studied. The objective of this study was to verify the effect of 5% aqueous extracts of M. chamomilla, M. ilicifolia and E. grandiflorus on C. noackae. Tests with eggs treated before being offered to the parasitoid female (pre-parasitism) and tests on which the eggs were treated 1 and 7 days after the female had performed oviposition (post-parasitism) were carried out. There was no difference between the treatments and the control group regarding parasitoid emergence in none of the tests. Although, there was increase in egg viability and number of emerged parasitoids when comparing the eggs treated 1 and 7 days after parasitism for all treatments. In conclusion, none of the plant extracts caused any harmful effect on C. noackae under lab conditions, indicating they may be an environment-friendly option to control the bronze bug of eucalyptus.
