Abstract

The present work was developed with the objective of evaluating the effect of the regrowth age on the chemical composition, digestibility and polyphenol content of the Jatropha curcas in an area of Cauto Valley. Was used piece of ground of Jatropha curcas with two years of establishment. A randomized block design with six replicas was used. The treatments were regrowth ages of 60, 120 and 180 days. At the beginning of each seasonal period a homogeneity cut was made at 1 m above the ground level. From there the sampling was carried out in 10 random plants eliminating the edge effect in an area of 0.5 ha, according to the treatments. The chemical composition of Jatropha curcas the dry matter content, DNF, ADF, ADL, increase with age with its best results at 180 days with 28.82; 51.53; 33.44 and 20.22%; while the CP and cellular content decrease with its highest results at 60 days 27.78 and 58.79%. The minerals showed a very variable behavior. The highest energy contribution and digestibility percentage at 60 days of age with a decrease of 11.04; 7.40; 8.90%; 1.58 and 1.11 MJ / kg. Polyphenolic compounds increase with age with the best results at 180 days of age with 11.26, 21.10, 113.93, 111.49 and 2.46 g / Kg, respectively; for total tannins, total phenols, TCT, TBCT and FTC. The results of the present investigation evidenced the marked effect of climatic factors and age on the quality of the Jatropha curcas, as the maturity of the forage progressed, its nutritional contribution decreased with a decrease in the CP, the nutrient content, digestibility and energy, as well as an increase in the fibrous fraction and the content of polyphenolic compounds.
