Efecto de inclusión de cebada (Hordeum Vulgare) en la dieta pollos de engorde de la línea Ross-308 en etapa de finalización.

Abstract

The present study was carried out in Cúcuta, northern Santander, with the objective of evaluating the effect of the inclusion of barley (Hordeum vulgare) in the diet of broilers of the ROSS-308 line, from the San Marino Bucaramanga poultry farm. The effects ofthe use ofbarley (Hordeum vulgare) and its beneficial effects on weight gain, feed conversion, productivity index and carcass yield in broilers were evaluated, analyzing the general weight, weekly weight increase, yield comparison, to evaluate the production cost per bird. An experimental study with a quantitative approach was used, a variable was intentionally manipulated to analyze the results at different levels of inclusion ofbarley in the diet of broilers. A statistical factorial model A x B was used, where A = (sex ofthe bird: male and female) x B (three levels of inclusion: 0, 5 and 10 % of barley (Hordeum vulgare) with three replications, the experimental unit being a cage containing 5 birds. The factorial model was 3 x 2 (3 diets and 2 sexes). In the results obtained for the variables according to the diets evaluated, the final weight (g), the birds fed with the control diet and the diet with 5% inclusion presented statistical differences (P≤0.05) with respect to the diet with 10% inclusion, showing the highest final weight in the latter (2428.93 ± 164.72). The highest weight gain was obtained with D10% (1588.47 ± 170.24) and the birds fed with D0% (1489.38 ± 92.24) and D5% (1450.77 ± 191.92) presented the lowest weights. In terms of feed conversion, the best results were obtained with the D10% diets, when analyzing the conversions obtained with D0% and D5%. It can be indicated that weight gain, feed conversion and carcass weight give good results with inclusion levels ofup to 10% (Hordeum vulgare) in the diet of broilers of the ROSS-308 line. As for the economic analysis, it was determined that the production of one kilogram of feed with the inclusion of barley (Hordeum vulgare) represents a higher cost than acquiring one kilogram of commercial concentrate.
