Produção de forragens nativas usando água residuária e avaliação de feno de maniçoba no desempenho de frangos caipira.

Abstract

It was aimed at to verify the effect of the residuary water use of carcinocultura tanks and fish farming in the irrigation of native forages and the effect of the pardal substitution of the conventional ration for the maniçoba hays about the acting and quality of carcass of chickens of cut tacky type. The experiments formed accomplished in the experimental farm in the municipal district of Barra de Santa Rosa. For the test with the residuary water maniçoba were used, herb salt, jureminha and silk flower. I begin it of the experiment she felt for the production of seedlings through estaquias and seeds. The percentages of germination and arising of the forages (fodder plants) and final stand of 6 months of the same ones in the field. To the six months a cut was accomplished in the herb salt and jureminha and made one it bromatologic analyzes of the whole plant and of the parts of the herb salt. One was also accomplished it analyzes of the quality of the used water. In the acting with the birds, 192 animais of four lineages were used with age of 38 days. The birds had been weighed and distributed in an entirely casual ized delineation, with three treatments and four repetitions constituted by 16 birds (two couples of each lineage). The treatments consisted of the substitution of 0, 7,5 and 15% of the basal ration for the maniçoba hay. The appraised variables had been : ration consumption (CR), weight gain (GP), alimentary conversion (CA), final weigh (PF), absolute and relative weigh of the noble cuts, abdominal fat and eatable vísceras (heart, gizzard and liver). It was still accomplished analysis morfométrica of the small intestines and thick. To the 80 days of age the animais were ali abated. For the brotação indexes it is germination, the forages showed a good propagation efficiency. The forages were shown quite resistant to the conditions of semi-arid and with a good development when irrigated with residuary water of fish farming and carcinocultura tanks. In agreement with the composition data, the plant herb salt presented a good forager potential when compared with the jureminha, same being irrigated with water containing high tenor of salts. The use of up to 7,5% of substitution of the ration is a viable alternative, where superior levei can come to interfere in the meat production.
