[Potentiality of silage elaboration with crop residues of five horticultural species]
1993
Vallejo G, Osvaldo Juan
At the Antumapu Experiment Station, a research was carried out in order to study the possibility of making silage with horticultural residues from Lycopersicum esculentum (tomato), Apium graveolens (celery), Cucumis melo (melon), Vicia faba (broad bean) and Phaseolus vulgaris (bean). The objectives of this study were to quantify the amount of residues available per hectare for each of the crops; to know the nutritive value of fresh residues and at different stages of fermentation and to know the quality of the silage. Four treatments, corresponding to 5, 10, 15 and 30 days of silage, and four replications per each were designed. Results indicated that the availability of these residues per hectare was variable, being the highest for tomato, with 4.238 kg of dry matter and the lowest for melon, with 1.684 kg of dry matter. Residues analyzed showed high values of water content, protein content, soluble carbohydrates and ashes. Also, they had high values of dry matter digestibility and medium to low values of cell wall. The nutritive value of the silage was high, comparable to that of a good quality corn silage, but with a higher content of crude protein. The quality of residue silage was variable, best results being obtained with bean and celery residues, followed by broad bean and tomato. The poorest results were by melon silage. The quality and nutritive value of the silage elaborated in this study clearly justify their utilization as feedstuffs for ruminants. However, further trials should be carried out to determine intake levels of these materials as well as their inclusion levels in the rations
