Effects of an organic modifier on body weight gain in zebu cattle in the tropics of Peru
The aim of this study was to evaluate the effects of a commercial organic modifier (Modivitasan) on body weight gain in zebu cattle. Thirty six Nellore steers were used. Animals were 25 ± 7.7 months old and had an initial body weight of 208.9 ± 40.2 kg. They were distributed in a treated group (n=20) that received three I.M. injections (1 ml/50 kg b.w.) of the organic modifier at 30 day-interval, and in a control non-treated group (n=16). Both groups were kept under a rotational grazing scheme in three paddocks with a mixture of Brachiaria decumbens, B. brizantha, Pueraria phaseloides, Paspalum plicatulum and Desmodium ovalifolium for 90 days. Animals were dewormed with 3.15% Ivermectin 15 days before the trial. Body weight gain in the treated group was 43.4 ± 9.2 kg and in the control group was 30.1 ± 5.4 kg (p<0.01). The superior body weight gain of the treated group could be explained for the additional supply of minerals, energy, vitamins and proteins contained in the organic modifier in a herd that was under detrimental nutritional conditions before the study. The use of the organic modifier would constitute an alternative for improving the efficient use of low quality pastures in the tropical lowlands of Peru.

El objetivo del presente estudio fue evaluar el efecto de un modificador orgánico (MO) comercial (Modivitasan) sobre la ganancia de peso de ganado cebú. Se utilizaron 36 toretes Nellore de 25 ± 7.7 meses de edad y con peso inicial de 208.9 ± 40.2 kg, distribuidos en un grupo tratado (n=20) con tres aplicaciones del MO, vía IM, en dosis de 1 ml por cada 50 kg/p.v. con intervalos de 30 días, y un grupo control no tratado (n=16). Ambos grupos estuvieron en un sistema de pastoreo rotacional en tres potreros sobre una mezcla de Brachiaria decumbens, B. brizantha, Pueraria phaseloides, Paspalum plicatulum y Desmodium ovalifolium por 90 días. Los animales fueron desparasitados con Ivermectina al 3.15% 15 días previos al inicio del estudio. La ganancia de peso del grupo tratado fue de 43.4 ± 9.2 kg y la del grupo control fue de 30.1 ± 5.4 kg (p<0.01). La mayor ganancia de peso en el grupo experimental se explicaría por el aporte adicional de minerales, energía, vitaminas y aminoácidos del modificador orgánico, lo que podría sugerir que el hato se hallaba en una situación de deficiencia marginal importante antes del inicio del experimento. El uso del modificador orgánico constituiría una alternativa para el mejor aprovechamiento de las pasturas de baja calidad del ganado bajo las condiciones de la selva baja del Perú.
