RESUMO
This study aimed to measure the consumption of different types of plant waste by the diplopod species Trigoniulus corallinus, in order to determine which would be the most suitable for the millicomposting process. To this end, a waste consumption experiment was carried out in the laboratory, using a completely randomized experimental design with 15 replicates and 13 organic residues from different sources. After 10 days, the following parameters were evaluated: dry mass of the waste used to feed the diplopods, dry mass of the fecal pellets, and diplopod mortality. Significant differences were observed in the consumption rates of the diplopods in the different treatments, with the highest rates being observed for Mimosa caesalpiniifolia, with 44.49%, followed by Gliricidia sepium chips, with 38.24%. The highest values for pellet mass were obtained from the decomposition of Mimosa caesalpiniifolia litter (0.891 g). The treatment with Syngonium auritum shavings showed 93% mortality after consumption, followed by the treatment with Heliconia psittacorum shavings, which showed 53%. Both species are ornamental and widely found in gardens and backyards. The diplopods have a preference for Mimosa caesalpiniifolia litter and Gliricidia sepium shavings. There is limited consumption of ornamental plant waste, with reports of toxicity to other organisms. Based on these results, a mixture of waste will be tested for millicomposting in urban farming areas that excludes toxic plants.

Prothrombin time (PT) and the activated partial thromboplastin time (aPTT) are useful tools for the diagnosis and monitoring of coagulation disorders in Veterinary Medicine. Our objectives were: to establish reference intervals (RI) for PT and a PTT for the dog using the Start®4 (Stago), to compare the obtained RI with literature; to evaluate the effects of gender and age on the coagulation profile. Plasma samples of 122 healthy dogs (57 males; 65 females) aged between 4 months and 18 years, divided into three age groups (0-2 years old; 3-10 years old; > 10 years old) and grouped in to males and females were analysed. The RI were estimated following the ASVCP guidelines with the Reference Value Advisor software. The RI were: PT 6.7'' to 10.8''; aPTT 9.0'' to 14.8''. PT was significantly higher in females than in males. Dogs aged 10 years or older have significantly higher mean aPTT times than younger dogs. RI comparison showed a considerable percentage of cases outside the reference RI of the literature (PT - 79.3%; aPTT - 77.1%), demonstrating the need of each laboratory to calculate its own RI. The RI established in this study are applicable for the coagulation profile assessment in dogs.
O tempo de protrombina (TP) e o tempo de tromboplastina parcial ativada (TTPa) são ferramentas úteis para o diagnóstico e monitorização das alterações da coagulação em Medicina Veterinária. Os objetivos deste estudo foram: estabelecer intervalos de referência (IR) para TP e TTPa para o cão utilizando o Start®4 (Stago), de modo a comparar os IR obtidos com a literatura; avaliar os efeitos do sexo e da idade no perfil da coagulação. Foram usadas amostras de plasma de 122 cães saudáveis (57 machos; 65 fêmeas) com idades entre quatro meses e 18 anos, divididos em três grupos (0-2 anos; 3-10 anos; > 10 anos) e agrupados em machos e fêmeas. Os IR foram calculados seguindo as diretrizes da ASVCP com o software Reference Value Advisor. Os IR obtidos foram: PT 6,7 '' a 10,8 ''; TTPa 9,0 '' a 14,8 ''. O TP foi significativamente maior nas fêmeas do que nos machos. Os cães com 10 anos ou mais apresentaram tempos médios de TTPa significativamente maiores do que cães mais jovens. A comparação de IR mostrou uma percentagem considerável de casos fora do IR de referência da literatura (TP - 79,3%; TTPa - 77,1%), confirmando a necessidade de cada laboratório calcular seu próprio IR. Os IR estabelecidos neste estudo são aplicáveis na avaliação do perfil hemostático em cães.
