Generally, the improvement of forage production seeks to increase biomass yield and productivity, mainly evaluating the yield of green forage, dry matter and in some cases the plant height however, it is important to evaluate the nutritional composition, especially the yield and quality of protein. The production of ryegrass in 2018 was 196,384 tons and the harvested area was 6,656 ha, with a yield of 29.5ton ha -1.
29,649.30 ha are corresponding to cultivated pastures, of which 27,633.20 ha are in the Junín mountain range. In the Junín region, the area of natural pastures is 1,104 300.04 ha. Īmong the most used pastures, ryegrass, in association with alfalfa and clover, are important for feeding cattle and other herbivorous species in the inter-Andean valleys of Peru they have a useful life of 3 to 5 years, with a biomass production of high nutritional quality. The livestock sector is the world’s largest consumer of agricultural land, through grazing and use of forage crops however, about 20% of pastures have deteriorated due to overgrazing and compaction.
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. The application of 10 t ha-1 had no greater effect in front of the control. 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 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.
