Elaboration and costs multi-nutritional blocs with goatee leaves (Pithecellobium acatlense) consumed by goats in the Mixteca Poblana, Mexico

摘要

The elaboration of multinutritional blocs (MB) is an alternative that allows supplement energy, protein, vitamins and minerals, and additionally, it can be administered and take natural resources as protein banks, mainly in the dry season, raising their cost and the concentrates decreasing profitability to producers. An aid is green or dried foliage of the tree-shrub of the Mixteca Poblana that drop their leaves to the ground (dry hay) in the dry season, thus becomes valuable forage consumed by goats, being great for your protein content and low cost in diets of small ruminants in silvopastoral production systems, at the dwindle the foliage of woody perennials in a time of the year. The aim of this study was to develop and meet production costs multinutrient blocks with goatee sheets (Pithecellobium acatlense) consumed by goats in the Mixteca Puebla. The study was done in the community of Tehuaxtla, belonging to the municipality Piaxtla in the Mixteca Poblana, which shows a secondary vegetation (arboreal, shrubby) that is consumed by goats in that region. 8 multinutritional blocks were used with Pithecellobium acatlense into two groups of 30 goats. Chemical analysis threw goatee 11.7% CP during the dry season and 14.8% CP for rains regarding consumption of BM group A showed 20% less compared to Group B, with respect to consumption of the block multinutrient the group A was 56 g/day/goat, whilst the group B has consumed 73 g/day/goat, where he converted ±0.14 g/goat/day for this preparation (MB), with a cost /goat when consuming block/8 days 0.14 USD.
