Resumen

In Peru, large volumes of chicken manure are produced, whose compost applied at normal levels improves the ryegrass yield and protein intake, to obtain organic products and contribute to animal, environmental and human health. To evaluate the biofortifying effect of Chicken Manure Compost (CMC) incorporated in (T1): 0, (T2): 10 and (T3): 20 t ha-1 levels, on Green Forage (GF) yield, Dry Matter (DM), Total Protein (TP) and Plant Height (PH) of Italian ryegrass, in pasture located in Huancayo, Peru (3250 altitude); two cuts were made, the first one was 42 days after the first fertilization and the second was 42 days after the first cut and second fertilization. In second cut, GF yield, in T1, T2 and T3 was 70.05; 61.50 and 97.20 t ha-1 (P <0.05); the DM yield was 10.39; 8.44 and 23.34 t ha-1, respectively (P <0.05); TP yield was 1.76; 1.74 and 2.80 t ha-1, respectively (P <0.05) and the PH was 97.0; 93.8 and 99.63 cm, respectively (P <0.05). The application of 10 t ha-1 had no greater effect in front of the control. The use of 20 t ha-1 of CMC allows to obtain organic forage with higher yield of dry matter and protein and therefore it is possible to obtain organic livestock products, with the advantage of reducing the negative impact of bird manure to public health, when is traditionally eliminated to environment.
