Efecto de los taninos del fruto del cascalote (caesalpinia coriaria jacq. willd) sobre el comportamiento productivo, parámetros de fermentación ruminal, rendimiento y calidad de canal caprina

Abstract

Leaves and fruit of trees and shrubs containing secondary metabolites such as tannins are alternative resources for ruminants feeding. Secondary metabolites modified ruminal fermentation by inhibiting the ruminal NH3-N and CH4 productions, and this can help to increase the content of conjugated linoleic acid (CLA) in milk and meat. They provide nutrients to the animal, they work as antiparasitic and antioxidants in the meat, . Therefore the objective of the present study was to evaluate the dietary inclusion effect of condensed tannins, of cascalote fruit (Caesalpinia coriaria Jacq. Willd.) on the productive performance, ruminal fermentation parameters, yield and carcass characteristics in goats during 56 days, with periods of evaluation every 14 days. Twenty male goats were used (Nubia x Criollo, 18 ± 3 kg of live weight), were assigned under a completely randomized of 4 treatments (5 repetitions) as follow
