Item Efeito da inclusão de farinha de minhoca com e sem zeólita natural na dieta de tilápia (Oreochromis niloticus) sobre os parâmetros de carcaça(2022-10-07) Oliveira, Elton Francisco de; Ludke, Maria do Carmo Mohaupt Marques; http://lattes.cnpq.br/4629657233206289; http://lattes.cnpq.br/3930176884309812The purpose of this research is to evaluate the effect of the addition of earthworm flour and the inclusion of zeolite (clinoptilolite) on carcass composition parameters. In the experiment, 280 tilapia of the species Oreocrhomis niloticus were used, with an initial and final weight of 2.826±0.0896g and 13.59±0.75g, respectively. The treatments were 8 diets corresponding to a 4 x 2 factorial arrangement, with 4 levels of inclusion of earthworm flour (0, 3.5; 7.0 and 10.5%) and levels of 0 and 2% of zeolite (Clinoptilolite ), the fish were distributed in a randomized block design with 5 replications. The following parameters were evaluated: carcass yield (RC), carcass dry matter (MSC); carcass organic matter (MOC); Mineral Substrate Matter (MMC); carcass energy based on dry matter (EMSC); ethereal substrate extract (EEC); energy retention coefficient (CRE); crude carcass protein (CBP); RE= Energy retention coefficient; CRP= Protein retention coefficient; TEP= Protein Efficiency Rate; IHE= Hepatosomatic Index; IVS= Viscerosomatic Index; At the end of the experiment (85 days) the animals were stunned with eugenol and then sacrificed and frozen, later they were lyophilized for analysis. The data were submitted to analysis of variance, in order to observe the main effects and the interaction between the factors (Worm meal levels and Zeolite inclusion) on the composition and protein and energy retention in the fish body. All analyzes were performed using the GLM procedure of the SAS computational package, at a 5.0% significance level. According to the data, there was a significant reduction in the amount of lipdis (p=0.0208) and in the energy retention coefficient (CRE) (p=0.0376) in the carcass of these animals when adding Zeolite in the diets. As for earthworm meal, a significant effect (p=0.0500) on CRE was observed, where when performing the regression there was a linear increase (P=0.0188) when including this ingredient in the diets of these fish. With this, we can add up to 10.5% of earthworm meal in diets for Tilapia, however Zeolite reduced energy efficiency, not interfering with other carcassItem Avaliação da composição corporal através da tomografia computadorizada em cães submetidos à restrição calórica(2022-06-12) Madruga, Luiza Borba de Almeida; Costa, Fabiano Séllos; http://lattes.cnpq.br/6876055943439186; http://lattes.cnpq.br/7933258477308497Item Validação de equações de predição da composição química da carcaça de ovinos Santa Inês(2021-12-03) Soares, Raquel Cristina Carvalho; Véras, Antonia Sherlânea Chaves; http://lattes.cnpq.br/0074248045711399; http://lattes.cnpq.br/1279928414920644With the growth of sheep farming in Brazil, further studies in the field of nutrition are needed in search of better carcasses with a view to greater meat production and better quality meat. From this premise, equations were proposed to estimate carcass chemical composition in ruminants. However, one of the most widely used methods is the section between the 9th and 11th ribs, which was initially tested on taurine, and has also been evaluated for predicting the chemical composition of the sheep carcass. In one study, equations were proposed to predict the chemical composition of the carcass of sheep using data from different experiments conducted, using among other independent variables the section of the 9th and 11th ribs. However, these equations need to be validated. Therefore, the objective was to evaluate the prediction equations of: water; protein (PB); ether extract (EE) and energy (EN) in the carcass of Santa Inês sheep. The carcass water, EE and EN contents were satisfactorily estimated, proving to be accurate and accurate models. However, to estimate the CP contents, the model was accurate, but not very precise, needing adjustments to better estimate the carcass protein of Santa Inês non-castrated male sheep.Item Predição da composição física e química da carcaça por meio da perna em ovinos Santa Inês(2020-10-30) Souza, Elder Bruno de; Véras, Antonia Sherlânea Chaves; http://lattes.cnpq.br/0074248045711399; http://lattes.cnpq.br/1503874613747770The objective of the present work was to evaluate whether the physical and chemical compositions of the leg cut can predict the physical and chemical compositions of the Santa Inês sheep carcass and generate simple linear equations for the prediction of these components in the carcass. 42 male Santa Inês lambs were used, un-castrated, with BW 19.48 kg ± 1.86 kg, and aged between 6 and 7 months, housed in individual pens provided with feeders and drinkers, and fed with a roughage:concentrate ratio of 50:50 in diet. After 14 days of adaptation of the animals to management and diet, four animals were slaughtered, and the others after 63 experimental days. Before slaughtering, all animals were weighed after fasting solids for 16 hours to obtain body weight at slaughter (SBW). After slaughter and obtaining the carcass, it was cooled to 4 ° C for 24 hours, for later obtaining the cold carcass weight (CCW). In a refrigerated environment, the carcasses were divided in the dorsal midline to obtain two half carcasses, sectioning the left half carcass in the meat cuts neck, palette, rib, saw, loin and leg that were weighed, placed in plastic bags, vacuum packed and frozen for further dissection, removed from the freezer and thawed in a refrigerator at 4 ° C. The dissection aimed to separate and quantify (g) the physical components of muscle, fat, bones and other tissues. The physical composition of the half carcass was obtained by adding the physical components of the leg and the rest of the carcass. The correlations between the physical and chemical components of the reconstituted carcass and the respective physical and chemical compositions of the leg were evaluated. The criteria adopted for the classification of the correlation coefficients (r) were strong (r> 70%), moderate (30% < r < 70) and weak <30%. The correlated data (P <0.05) were used to propose parameters of simple linear equations to predict the physical and chemical components of Santa Inês sheep carcass from these constituents in the leg section. There was a moderate to strong correlation between the tissue and chemical components of the cut leg and their respective components in the carcass. Simple linear equations were proposed to predict these components in the carcass. The physical and chemical composition of Santa Inês sheep carcass can be predicted by means of the physical and chemical composition of the leg.Item Perfil antropométrico e fisiológico de jovens em idade escolar praticantes de natação(2019-02-06) Silva, Flávio Henrique Viana da; Lima, Anna Myrna Jaguaribe de; http://lattes.cnpq.br/6743434574905339; http://lattes.cnpq.br/9683009795205478The body composition of the world population, including children and adolescents, has undergone changes in its characteristics. There is a reduction in malnutrition rates and an increase in the number of overweight and obese children and adolescents, thus determining a nutritional epidemiological transition. The regular practice of physical exercise is among the behavioral habits that can bring benefits in both the short and long term. Therefore, the study aimed to describe the anthropometric and physiological profile of children and adolescents, of school age, that takes swimming lessons. The sample that originated the data was composed of 56 students from the University’s Project named Barbatanas da Rural, 40 boys and 16 girls, aged 12.6 ± 2.1 years old. The evaluations were carried out at the Physical Education Department of the Federal Rural University of Pernambuco and the components were the body mass index (BMI), the fat percentage through the sum of triceps and subscapular folds, the static force through the handgrip test, the flexibility through the sit and reach test, upper limb strength through the arm flexion test and abdominal resistance through the abdominal flexion test. Regarding BMI and fat percentage, there was no difference between the sexes. However, for BMI, 17.86% of the sample was overweight and 23.21% of the sample was obese, with boys averaging 20.78 ± 4.78 kg / m2, girls 20.72 ± 3.25 kg / m2 and the total sample 20.76 ± 4.37 kg / m2. For the fat percentage, 23.21% of the sample was moderately high, 10.71% high and 12.50% excessively high, presenting the boys an average of 21.23 ± 11.22%, the girls 24.39 ± 4.29% and the total sample 22.14% ± 9.82%. There was no difference between boys and girls when comparing the values of flexibility (22.13 ± 7.38cm vs. 24.43 ± 7.97cm, respectively) and the number of arm flexion repetitions (9.48 ± 7.86 repetitions vs. 7.00 ± 4.89 repetitions, respectively), remaining only 44.64% of the sample above the average for the flexibility values, with a distribution of 56.25% of the female sample and 40.0% of the male sample. For arm flexion, 73.21% of the sample was above average, with a distribution of 93.75% of the girls and 65% of the boys. The boys presented higher values in the handgrip test (26.72 ± 9.65 kgf vs. 20.75 ± 3.40 kgf, respectively) and in the abdominal test (29.1 ± 10.71 and 24.00 ± 5, 05 repetitions) when compared to girls. 100% of the sample had values below the average for the handgrip test and 87.50% of the abdominal resistance sample was below average, with a distribution of 82.50% of the boys and 100% of the girls. Based on the results obtained, we observed that a large percentage of the sample was overweight, obese and fat percentage above ideal values. In addition, static strength and abdominal resistance were higher in boys compared to girls; flexibility and arm flexion showed no difference between groups.
