Valoración nutricional de la harina de tamo de maíz de la zona de Tambillo y su respuesta en el crecimiento y engorde de conejos

Abstract

In the laboratory of Animal Nutrtion and Food Science, Faculty al Animal Science, ESPOCH, proximal analysis of corn flour chaff on Tambillo area, Pichincha province was conducted with the following results 11.51% humidity, 4.06% ash, 7.05% crude protein, crude fiber 41.60%, 1.00% E.E. and 34,78% E.L.N. Cell walls was 72.81% for the FDN, 41.50% FAD and 5.77% lignin. The physical propertis of the fiber was 14.52% for solubity, 0,28g/ml density, volumen 18ml, 0,34 water adsortion capacity of 3.76 meq CBa, 2,69 meq CBb. The organic matter digestibility was 32.22 ±0.44%. They were then evaluated different levels of this grass (10-20-30%), in the feeding of the New Zealand breed rabbits, to the stages on growth and fattening with a control treatment (0%), 40 experimental units used. Submitted to analysis of variance and separation of means by Tukey test, the best effect was obtained with treatment 30%, resulting in highly significant differences for feed consumption of 3.22kg in the growth stage and 3.46 kg in the fattening phase. For other variables, weight again, feed intake, feed conversion, carcass weight and dressing percentage no significant differences were obtained. The higher profitability (B/C of 1.42), was to inclused 30% of this cereal, so it is recommended to include this level of corn flour chaff for feeding rabbits.
