Evaluation of six tree shrubs consumed by goats in Mixteca Poblana, Mexico

Abstract

An evaluation of the nutritional composition of six tree shrubs (Palo de Brasil, Barba de chivo, Huamúchil, Tlaxistle negro y Cubata) consumed by goats was carried out In Maninalcingo and Tehuaxtla communities, located in Mixteca region, Puebla, Mexico, during the rainy season. Three family production units, where leaves, flowers and fruits were collected, were analyzed. In order to compare average hourly bite and the part of the plant consumed by goats Tukey test was applied together with descriptive statistics, the latter to determine the dispersion among bromatological components of the different parts of each plant in the total population of tree shrubs evaluated. The samples were constituted of 200 green weight grams (dehydrated after). Organic matter (MO), ash (Ce) and raw protein (PB) were obtained AOCA technique (1997). For the case of neutral detergent fiber (DDN), acid detergent fiber (FDA) and lignin (Lig.) Van Soest method was used. Results show that Huamúchil (Pithecellobium dulce) mixed with leaf and sheath had a better PB rate (18.3% ±1.08), being the best PB rate (14.4% ± 0.42) for Tehuistle (Acacia bilimekii var. Robusta Miranda) leaf fraction and 94.4%±1.02 in MO. Huamuchil mixed with leaf and sheath showed also the highest rate of Ce (12.3±0.88), while the mixture of Cubata sheath and rind achieved 52.7%±1.8 and 49.8%±1.04 of FDN y FDA, respectively. In the case of lignin, Tehuiste leaf achieved 18.4%±0.98.
