| Diğer Bilgiler: | Introduction. Forage legumes complement the forage offer and the protein content in grass-based cattle feed; however, there is little availability of these species adapted to the conditions of the dry colombian Caribbean. Objective. To evaluate the production and quality of forage from shrub legume genotypes during the rainy and dry seasons of the year in the colombian dry Caribbean. Materials and Methods. Dry forage production (PFS; kg ha-1) was measured and nutritional value was estimated by near-infrared spectroscopy (NIRS) in two genotypes of Leucaena diversifolia (LD15551, LD21242), one of Cratylia argentea (CA2238) and in Leucaena leucocephala cv Cunningham (control) during the rainy and dry seasons of 2018 and 2019. Analysis of variance was performed to determine the effect of species, season and its interaction under a randomized completed block design with a factorial structure. Results. The control presented the highest DFY with 1288.9 kg (p < 0.05; average seasons), the highest crude protein contents (CP; 24.7 %, p < 0.05) and dry matter digestibility (DMD; 73.7 %, p < 0,05) in the rainy season compared to the other materials. In CA2238 the highest neutral detergent fiber content (NDF) was observed with 45.9 % (p < 0.05; average seasons) and the lowest gross energy contents (GE; p < 0.05) in the rainy season and in the dry season (4.15 and 4.09 Mcal kg-1 DM). Conclusion. Differences were observed in forage production associated with the species and in most of the quality components evaluated associated with the species and time of year in which L. leucocephala showed the highest yield and similar quality to other genotypes. |
