Los principales géneros de hongos potencialmente toxigénicos en la cadena productiva de la maca son el Fusarium, Penicillium, Aspergillus y Rhizopus, el primero procedente del campo y los restantes durante su manipulación poscosecha. La humedad de la maca fresca, es precursor de su presencia en la cadena productiva. La humedad en las harinas de maca cruda, gelatinizada y precocida inhiben su crecimiento sin embargo los tratamientos tecnológicos no garantizan su ausencia en el producto. Los azúcares reductores en la maca y derivados son el principal sustrato y el pH en ellos es óptimo para el crecimiento de los hongos.

Summary The reproductive performances of livestock play an essential role in the economic management of the farm. The improvement of semen quantity and quality through the use of food supplements that lack substances which are forbidden in animal feeding, or that may have detrimental effects, is an important goal. Maca (Lepidium meyenii) is a plant that has been used for centuries in the Andes for nutrition and fertility enhancement in humans and animals. The aim of this study was to evaluate the effects of food supplementation of stallions with maca during the breeding season on spermatozoa parameters such as DNA fragmentation and shape, which are two predictive indexes of spermatozoa functionality. For this purpose, ejaculate volume, semen gel-free volume, sperm concentration and motility, total sperm count, sperm DNA fragmentation and sperm head parameters (length, width, perimeter, area, shape factor, roughness) were measured in four stallions. Maca food supplementation in stallions during breeding reduced the percentage of spermatozoa with fragmented DNA, increased significantly sperm concentration and exerted an elongation of the spermatozoa head, a condition that is believed to improve spermatozoa functionality, suggesting that food supplementation of maca could be useful in horse breeding during the breeding season.
