“…A proteína total e a glicose sanguínea não foram afetadas pela composição das dietas. Segundo Camargo et al (2005), a elevação da proteína da dieta de 30 para 50% resultou em aumento linear do hematócrito de alevinos de jundiá (de 33 para 38%). Entretanto, Melo et al (2006a) observaram que o hematócrito do jundiá aumentou significativamente até 27% de proteína da dieta, e, após isto, houve redução nos valores dessa variável.…”

“…A carpa capim (Ctenopharyngodon idella), embora tipicamente herbívora, apresenta crescimento reduzido e deformidades quando alimentada exclusivamente com forragem, devido à deficiência de vitaminas e aminoácidos essenciais (Camargo et al, 2006). O teor de proteína da dieta recomendado para juvenis de carpa capim até 10g varia de 22 a 48% (Ding, 1991) e está relacionado a diversos fatores, como tamanho, idade do peixe e temperatura da água.…”

RESUMOAvaliou-se a resposta de juvenis de carpa capim (Ctenopharyngodon idella) à inclusão de proteína bruta (PB) em dietas práticas, em um experimento com 120 juvenis e 80 dias de duração. As dietas eram compostas por farinha de carne suína, farelo de soja, milho e farelo de trigo com 22, 30, 36 ou 44% de PB. Dez juvenis (153,0±1,5g) por tanque (850L) foram alimentados duas vezes ao dia (3% da biomassa). Foi observado efeito linear positivo da PB para peso final, ganho em peso, taxa de crescimento específico, rendimento de carcaça e filé, coeficiente de retenção proteica, taxa de eficiência proteica, deposição de gordura e proteína e hematócrito. O mesmo efeito também foi observado para triglicerídeos e colesterol total no sangue, indicando que a proteína da dieta foi utilizada como fonte energética. Conversão alimentar aparente e gordura no peixe inteiro apresentaram efeito quadrático, com pontos de máxima em 40,6 e 37,1% de PB, respectivamente. Pode-se concluir que a porcentagem mínima de PB para a carpa capim na fase de recria foi de 44% e que a variação da proteína da dieta promoveu alterações no metabolismo dos juvenis de carpa capim, refletidos nos parâmetros sanguíneos e de carcaça.Palavras-chave: peixe, Ctenopharyngodon idella, deposição de gordura, ganho de peso, parâmetros sanguíneos, recria ABSTRACT

“…Nutritional requirements of fish are usually determined on nutrient dose–growth response trials. However, several studies have demonstrated that differences in haematopoiesis and blood cell function can also be indicative of dietary manipulation (Greene & Selivonchick 1990; Klinger, Blazer & Echevarria 1996; Camargo, Pouey & Martins 2005). Interrelationships between macro responses, such as growth and metabolism, are controversial especially in warm water fish and data relating dietary protein contents and metabolism remain scarce, especially regarding Brazilian novel aquaculture species (Vieira, Inoue & Moraes 2005).…”

Haematopoiesis and blood cells'functions can be in£uenced by dietary concentration of nutrients. This paper studied the e¡ects of dietary protein:energy ratio on the growth and haematology of pacu, Piaractus mesopotamicus. Fingerling pacu (15.5 AE 0.4 g) were fed twice a day for 10 weeks until apparent saciety with diets containing 220, 260, 300, 340 or 380 g kg À 1 crude protein (CP) and 10. 88, 11.72, 12.55, 13.39, 14.22 MJ kg À 1 digestible energy (DE) in a totally randomized experimental design, 5 Â 5 factorial scheme (n 5 3). Weight gain and speci¢c growth rate were a¡ected (Po0.05) by protein level only. Protein e⁄ciency ratio decreased (Po0.05) with increasing dietary protein at all levels of dietary energy. Daily feed intake decreased (Po0.05) with increasing dietary energy. Mean corpuscular haemoglobin concentration was a¡ected (Po0.05) by DE and interaction between dietary CP and DE. Total plasma protein increased (Po0.05) with dietary protein and energy levels. Plasma glucose decreased (Po0.05) with increasing dietary protein. The CP requirement and optimum protein:energy ratio for weight gain of pacu ¢ngerlings, determined using broken-line model, were 271g kg À 1 and 22.18 g CP MJ À 1 DE respectively. All dietary CP and DE levels studied did not pose damages to ¢sh health. r 2008 Blackwell Munksgaard 486 No claim to original US government works Aquaculture Research, 2009, 40, 486^495 Growth and haematology of pacu A Ł J deAlmeida Bicudo et al. r 2008 Blackwell Munksgaard No claim to original US government works, Aquaculture Research, 40, 486^495 Ã Haematocrit. wTotal red blood cell count. zHaemoglobin. ‰Mean corpuscular volume. zMean corpuscular haemoglobin. kMean corpuscular haemoglobin concentration.

“…Haematological comparative studies between wildlife animals and those maintained in captivity from the same species showed variations for those parameters (Hasselmeier et al 2008, Pires et al 2009). Dietary differences between wildlife Giant anteaters and the ones in the present study have direct influence on erythrocyte production (Camargo et al 2005, Baeta 2015.…”

Giant Anteater (Myrmecophaga tridactyla Linnaeus, 1758) of the brazilian cerrado: hematology and storage effect. Pesquisa Veterinária Brasileira 37 (7): [773][774][775][776][777][778][779][780]. Laborató-rio Clínico Veterinário, Hospital Veterinário, Departamento de Medicina Veterinária, Escola de Veterinária e Zootecnia, Universidade Federal de Goiás, Rodovia Goiânia Km 8, Campus Samambaia, Goiânia, GO, Giant Anteater (Myrmecophaga tridactyla) is a vulnerable species because of progressive habitat destruction, mostly affected by wildfires and car accidents. The increasing number of animals that are attended by wildlife rescue centres reinforces the need of knowledge about haematological parameters, especially for those that inhabit Brazilian cerrado biome. For this purpose and in order to establish reference values for this species and also to compare them with previous studies, haematological analysis of captive giant anteaters from Brazilian cerrado were performed. Moreover, the alterations of blood samples after 24 and 48 hours of storage at refrigeration temperatures (4 o C) and preserved with two different EDTA concentrations (5% and 10%) were studied. Means and standard deviations of haematological parameters analysed immediately after collection were: RBC: 2,07 x106/µL ± 0,40; hematocrit: 38,08%± 5,93; haemoglobin: 11.33g/dL±2.15; MCV:186.52 fL±21.72; MCHC: 29.68g/dL±2.56; MCH: 55.08pcg±5,94; total leucocytes: 8.142/µL±2.441; neutrophils: 5.913/µL±2.168; lymphocytes: 1.460/ µL±740; eosinophil: 522/µL±385; monocytes: 247/µL±176; thrombocytes: 123.458/ µL±31.362 and total plasma protein: 6.23g/dL±0.49. This data shows evidence of the existence of important differences between these values and others from other areas, either from Brazil or from other South American countries. Those variations might be connected to environment, genetic, nutritional and/or management factors. Regarding the storage effect analysis, it can be concluded that in giant anteaters, haematological analysis can be performed until 24h after collection without any significant alterations on the haematological parameters, except for thrombocytes. Concerning the different EDTA concentrations, it can be concluded that there are no quantitative differences in haematological variables. Nevertheless, relevant morphologic alterations in blood cells can be observed after a 24h storage period, being most noticeable in the leucocytes. Those alterations can lead to misinterpretation of the results, interfering diagnosis, prognosis and treatment. (6,23g/dL±0,49). Tais dados permitem afirmar que existem importantes diferenças entre os valores hematoló-gicos destes em relação aos animais provenientes de outras regiões, tanto do Brasil quanto de outros países da América do Sul. Provavelmente, tais divergências estão associadas a fatores ambientais, genéticos, nutricionais e/ou de manejo. Quanto à análise das amostras estocadas, conclui-se que, em tamanduás-bandeiras, as amostras para a realização de hemograma podem ser processadas até 24 horas após a...
