Abstract
El presente trabajo de investigación se realizó en la Comunidad Campesina de Rosario de la Región Puno con el objetivo de evaluar la suplementación con concentrado en vacas Brown Swiss cruzadas alimentadas con forraje verde y conservado, sobre la producción y composición química de la leche durante la época seca. La base de la alimentación de todas las vacas fue con 7 kg de heno de avena + 6 kg de ensilado de avena + 3.5 kg heno de alfalfa + pastoreo con retoño verde de asociación de alfalfa, ryegrass y trébol de 4 – 6 kg por día y se plantearon tres tratamientos, T1: 0 kg concentrado; T2: 2 kg concentrado y T3: 4 kg de concentrado. Para analizar los valores de los parámetros productivos se utilizó un diseño de sobre cambio simple con juego de arreglo de diseño Cuadrado Latino 3 x 3 (3 vacas x 3 periodos), la evaluación se realizó en tres periodos y tres tratamientos con 6 vacas en cada periodo haciendo un total de 18 observaciones individuales. Se utilizaron 6 vacas Brown Swiss cruzadas multíparas de 3 a 4 partos durante el segundo tercio de lactación (106±21 días), distribuidas al azar durante 60 días suplementadas con concentrado en la época seca. Se evaluaron los parámetros de producción de la leche y composición química de la leche (proteína, grasa y sólidos totales). En cuanto a la producción de leche se encontró diferencia significativa (p≤0.05) de los tratamientos con suplementación (T2 y T3) en comparación al control (T1). En composición química de la leche como la grasa total, proteína total y sólidos totales, de la leche no se observó diferencias estadísticas por efecto de la suplementación con concentrado, registrando sólo diferencias numéricas (p>0.05) entre tratamientos. Se concluye que la producción de leche aumentó significativamente por efecto de la suplementación con concentrado en la época seca; sin embargo, la composición química de la leche fue similar entre tratamientos, no existiendo efecto significativo de la suplementación en la época de seca en la Región de Puno.
The present research work was carried out in the Rosario-Puno Farming Community with the aim of evaluating the effect of supplementation with concentrate in Brown Swiss crossbred cows fed with green and preserved forage, on the production and chemical composition of milk dairy cows during the dry season. The basis of feeding all the dairy cows was 7 kg of oat hay + 6 kg of oat silage + 3.5 kg alfalfa hay + grazing with fresh alfalfa shoots of 4 – 6 kg per day and three were treatments proposed, T1: 0 kg concentrate feed; T2: 2 kg concentrate feed and T3: 4 kg concentrate feed. A simple over change design with arrangement kit was used 3 x 3 Latin Square design arrangement (3 cows x 3 periods), the evaluation was carried out in three periods and three treatments with 6 cows in each period making a total of 18 individual observations. Six multiparous Brown Swiss crossbred cows with 3 to 4 births were used during the second third of lactation (106±21 days), randomly distributed for 60 days, supplemented with concentrate in the dry season. Milk production parameters and chemical composition of milk (protein, fat and total solids) were evaluated. Regarding milk production, a significant difference (p≤0.05) was found between treatments with supplementation; T2 and T3 compared to the control (T1). In chemical composition of milk such as total fat, total protein and total solids, no statistical differences were observed due to the effect of supplementation with concentrate feed, recording only numerical differences (p>0.05) between treatments. It is concluded that milk production increased significantly due to the effect of supplementation with concentrated in the dry season; However, the chemical composition of the milk was similar between treatments, with no effect of supplementation in the dry season in the Puno Region.
