The Chelonians represent one of the main bilological resourses of the Amazon region and stand as a important food source for the people that live by the rivers. For that reason, the possibility of commercial rising came forth. Biometries have been made to develop barometric equations in order to determinate the biometry of the amazon turtle and evaluate functions that can be.used for the barometry of the animals at two commercial rinsing fields. Living weight records was used separate heavy and light samples to each site. Because the great variation of the living weight, it was converted to logarithmic scale. To compare two different levels of years and sites, a multivariated variance analysis was performed. A discriminating analysis was adopted by using a canonic variable. The great living weight variation in each year and site reveals that in samples with same age and origin, the animals show great heterogeneity for living weight. The result of the canonic correlation for two rising fields indicates that the living weight can be explained in 86% and 96% when a linear relation is established. Excepting the head width and tail length variables, all others demonstrated highly correlated to the living weight. Therefore, there are a high variation of the living weight among animals created in captivity. The biometries are highly related to the living weight and should be included in studies that seek barometry.

Desempenho e características de carcaças de cordeiros suplementados com diferentes níveis de resíduo de biodiesel
(Universidade Federal do Pará, 2011-02-15) SOARES, Bruno Cabral; ÁVILA, Sandra Cristina de; http://lattes.cnpq.br/9683521652094464; http://lattes.cnpq.br/8940750096354420; SILVA, André Guimarães Maciel e; LOURENÇO JÚNIOR, José de Brito; http://lattes.cnpq.br/2919433679918544
Was aimed verify the effect from different levels of supplementation from biodiesel residue originating from dendê. Were utilized 25 male ovines, Mutt, gelded, with middleweight live of 20 kg. The experimental delineation utilized were randomized blocks, with 5 replicates per treatment, for the weight gain data and carcass characteristics. The biometrics data were analyzed in a subdivided parcel scheme. The experimental period was 84 days, with 14 days of adaptation and 70 days to obtain study variables. The feeding was split in 2 meals, at 7h00 and 17h00. Diets were composed 34% hay Panicum maximum cv. Massai and 61% concetrated, from broken corn, soy bran, minerals and 5% of dendê oil or dendê biodiesel residues, on increasing levels (zero, 25,50,75 and 100%), respectively. At the beginning of the trial period and each 14 days were realized morning weighings, before the first meal for performance evaluation, biometric measures and slaughtered on final of the trial period for carcass characteristics evaluation after passing 12h fasting of solids and liquid diet. Significant effects were observed (p<0,05) from inclusion levels of biodiesel residue originating from dendê. The regression equations presented increasing linear effect, for variables: dry matter consumption (DMC), live weight (LW), weight gain (WG), body score (BS), body length (BL), thoracic perimeter (TP), chest width (CW), and quadratic for PCQ, PCF,RCB, RB. Dendê biodiesel residues utilization, in replace of dendê oil on lambs food, promotes increasing effect on dry matter consumption and weight gain, improves carcass characteristics and becomes an alternative to increase energetic density of growing ovines diet.
