Design and evaluation of a technological system for bovine feeding in a calid zone at alto Magdalena

Abstract

The present study was carried out in AGRINSA CORP (Tolima), the objective was to evaluate a technological system of appropriate handling for the intensive bovine feeding. 30 young bull commercial Zebu were used with an average first weight of 210 kg within a design of blocks totally randomized in three treatments, which consisted on the inclusion of 57,7% (T1), 47,1% (T2) and 36,8% (T3), from the mixture of fuzz of Rice with brioler litter, the other ingredients were: Cotton seed, flour of rice, cotton dung, tortave, molasses, and a premixture of vitamins and minerals. The test took 105 days, when concluding the experiment an increase of live weight was observed, it was bigger in animals that were into the third Treatment (p <05) with values of 1,012 (g/day), followed by treatment two with 840 g/day and Treatment one with 680 gr/day. The evaluation of feed intake showed that the third treatment was the best, with statistics differences among the treatments (p <05); however the best nutritious conversion was evidenced within the second Treatment (6,91) overcoming to treatment three (7,04). In the digestibility analysis of diets, the best index obtained was in the third treatment with 63,38%, followed by the second treatment (59,11%) and the first Treatment (51,53%), in the same order the treatment with more profitability was the third Treatment (12,4%), in Treatment two was obtained a percentage of 9,94%, and the first treatment obtained a negative percentage of -6,58%. The handlings of the young bulls in mobile, folding and disable facilities were appropriate and completed the purpose for this design.
