Resumen
INTRODUCCIÓN: un aspecto importante en la nutrición de pollos de engorde esta referido a la
granulometría del alimento, que tiene un efecto benéfico en la digestión del alimento.
Generalmente se utilizan dietas peletizadas. Sin embargo, en dietas tipo harina cruda el tamaño
de las partículas es menor que el peletizado. Por lo que se requiere evaluar estrategias para mejorar
la granulometría del alimento en la fase de acabado. La utilización de granos de cereales entero
como el trigo mejora la granulometría del alimento y podría ser una alternativa para mejorar la
respuesta productiva de los pollos de engorde en la fase de acabado. OBJETIVO: evaluar el
efecto de la inclusión de grano de trigo entero en la dieta sobre la respuesta productiva, peso
relativo de órganos y margen sobre costo de alimentación de pollos de engorde macho en la fase
de acabado de 28 a 35 días de edad. MÉTODOS: de un lote de 200 pollos de sexo machos de la
línea Cobb 500, a los 28 días de edad, se seleccionaron 80 pollos de engorde. Se establecieron 4
dietas como tratamientos: testigo, sin inclusión de grano de trigo (T-1), 5% (T-2), 10% (T-3) y
15% de inclusión de grano de trigo entero (T-4). Los tratamientos fueron asignados
aleatoriamente bajo un diseño de bloques completamente al azar. Cada uno de los tratamientos
tuvo 4 repeticiones, dando un total de 16 unidades experimentales. Se evaluaron las variables de
peso vivo, ganancia de peso, consumo de alimento, conversión alimenticia, relación de eficiencia
proteica, conversión calórica, peso relativo de órganos, costo de alimentación, margen y
retribución económica RESULTADOS: la inclusión de grano de trigo entero afectó
significativamente (P<0.05) el peso vivo, ganancia de peso, consumo, conversión alimenticia,
eficiencia proteica, conversión calórica. El margen económico fue más alto con la inclusión de
granos de trigo. CONCLUSIÓN: la inclusión de 15% de grano de trigo entero en la dieta mejora
la respuesta productiva y mejora el costo de alimentación y margen económico en la fase de
acabado.
INTRODUCTION: An important aspect in the nutrition of broiler chickens is related to the feed granulometry, which has a beneficial effect on feed digestion. Pelletized diets are generally used. However, in raw meal type diets the particle size is smaller than in pelleted diets. Therefore, it is necessary to evaluate strategies to improve feed granulometry in the finishing phase. The use of whole cereal grains such as wheat improves feed granulometry and could be an alternative to improve the productive response of broiler chickens in the finishing phase. OBJECTIVE: evaluating the effect of the inclusion of whole wheat grain in the diet on the productive response, relative organ weight and margin on feed cost of male broiler chickens in the finishing phase from 28 to 35 days of age. METHODS: 80 broiler chickens were selected from a batch of 200 male Cobb 500 chickens at 28 days of age. Four diets were established as treatments: control, without inclusion of wheat grain (T-1), 5% (T-2), 10% (T-3) and 15% inclusion of whole wheat grain (T 4). The treatments were randomly assigned under a completely randomized block design. Each treatment had 4 replications, giving a total of 16 experimental units. The variables of live weight, weight gain, feed intake, feed conversion, protein efficiency ratio, caloric conversion, relative organ weight, feed cost, margin and economic return were evaluated. RESULTS: the inclusion of whole wheat grain significantly affected (P < 0.05) live weight, weight gain, intake, feed conversion, protein efficiency, caloric conversion. The economic margin was higher with the inclusion of wheat grains. CONCLUSION: the inclusion of 15% of whole wheat grain in the diet improves the productive response and improves the feed cost and economic margin in the finishing phase.
