Resumo: |
The aim of this work was to evaluate the technical feasibility of the use of gypsum, sodium chloride and plaster residue as a source of mineral for growing kid goats, and still study the clinical and nutritional aspects of their use. The results aimed at the technical and economic feasibility of raw materials and mineral supplement for goats. Such research helped in the generation of scientific data to enable future research involving gypsum, sodium chloride and plaster residue as a source of mineral supplementation in animal feed taking advantage of local gypsum and plaster residue for other purposes not only the construction. Six experimental groups of three Anglo Nubian breed goats were used aged 60 days. The animals were divided in accordance with the mineralization to be received: plaster residue (G1), Gypsum (G2), sodium chloride (G3), plaster residue associated with sodium chloride (G4), Gypsum associated with sodium chloride (G5), the control group that received no mineralization (G6). The animals received this treatment for 120 days and were periodically assessed by clinical examination, radiographic and laboratory tests, including blood tests, fecal tests and serum for biochemical analysis of calcium, phosphorus, magnesium, urea, creatinine and examinations bromatological diets. In the data analysis techniques were used descriptive statistics: absolute distributions, percentages, the statistical measures: mean and standard deviation and correlation coefficient of Spearman and inferential statistical techniques via statistical tests of Kruskal-Wallis test and the null hypothesis of correlation. Statistical tests were performed with an error margin of 5.0%. Given the various observations made during the study adding to the interpretation of the results of statistical analysis, concluded that, in the herd studied factors such as high degree of parasitism and the lack of mineralization in the diet can reduce body weight gain in kids in growth; the average weight in each group increased with time evaluation, the mean weight of G6 were correspondingly smaller groups of other mineralized, there was greater weight gain in G4 and good yield in bone mineralization. All the goals pursued by the results of this research are directly involved in the production of goat in several stages, the mineralization to be closely involved with many aspects of the productive development of ruminants. |
