Abstract

GUEVARA VIERA, Raúl V et al. Effect of Ground Corn Stalks on the Productive Response of Dairy Grazing Cows. Rev. prod. anim. [online]. 2016, vol.28, n.1, pp.16-22. ISSN 2224-7920.

The productive response of dairy grazing cows using ground cornstalks was assessed. The study was developed in two different Ecuadoran settings (Costa Region and Sierra). At the Costa, on a 29.1 ha farm, the cows grazed on star clusters (Cynodon nlemfuensis) and panic grass (Panicum maximum), with legumes of different genera, such as Alysicarpus, Centrosema, Desmodium, Galactia, supplemented with corn stalks, cv. INIAP 125. The animals received 0.46 kg from the third kg onward, and ground corn stalks in 30- and 28- day periods, respectively (M-30 and M-28), and a control group without stalks for 36 days (M-0). In another region, the estate had 14.2 ha and 23 milking cows, grazing on clusters of West African pennisetum (P. clandestinum) and rye grass-white clover (L. perenne and T. repens) and whole corn stalks (60-70 % ripe grain), at a ratio of 18 kg green/cow/day for 48 days and balanced at a ratio of 0.5 kg/l of milk following the fourth kilogram, and minerals. In both cases, stalks effected (P < 0.05) on cow response. In the Sierra region, the milk yield increase observed was 1.68 kg/cow, and in the Costa region, it was between 1.1 and 2.5 kg/cow. Corn stalks meant nutritional supplementation to grazing clusters in both regions, increased milk/animal yields, and cost reductions.
