Abstract

The tree-shrub vegetation consumed by goats was studied in three family-operated units of caprine production in the municipality of Piaxtla of the Mixteca Poblana in Mexico, during the rainy season (June to November 2004). The natural mountainous foraging land in question is composed of low, thorny deciduous forest, xerophytic vegetation, secondary tree-shrub vegetation, and small areas of oak trees and grassland. The climate is warm sub-humid with rain in summer (350 to 800 mm annual total) and semi-arid and hot in the dry season (23ºC annual mean temperature). Animal preference for the different plants and their parts was determined by observing the number of bites/h received and nutritional value by chemical analysis of vegetative material sampled between 8:30 and 12.00 h. Forty tree-shrub type plants were identified of which the following six species were the most consumed: Haemotoxylum brasiletto, Acacia bilimerkii var., A. pennatula, Pithecellobium acatlense, P. dulce, and Amelanchir denticulada. The percentage distribution of the plant parts consumed was: leaf, flower and fruit, 35; leaf, flower and pod, 23; flower and pod, 14; leaf and pod, 10; pod and bark, 8; bark, 5; and flower, 5. In percentage chemical composition the most favorable were P. dulce (leaf and pod) and A. dnticulada (leaf) with contents of PB, NDF and ADF of 18.3. 35.3, and 25.1; 13.1, 30.9, and 17.7, respectively, while A. bilimekii var. (leaf) was poorest with corresponding values of 14.4, 50.3, and 39.6.
