Abstract
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.
Highlights
IntroductionThe tropical regions of Mexico, held 36.8% of the national inventory of sheep and in a smaller percentage goats inventory, the predominant production system is extensive or traditional, where the diet of the animals depends on grazing and browsing native species of trees and shrubs, whose nutritional value decreases rapidly with maturity; and during the dry season, food is very nutritious usable [1].In this system, the caprines are kept in good state only 5 or 6 months of the year, retarding their growth and reproductive efficiency in the dry season; to counteract seasonal variations in forage availability is administered as a supplement block [2].When supplementing molasses in multinutritional blocks represents an alternative for easy use by small farmers, in addition to several regional ingredients, it can be used in the manufacture of the blocks
Pithecellobium acatlense or goatee, is considered a tree belonging to the legume family, it is highly edible plant goats of the MixtecaPoblana
With regard to Pithecellobium acatlense consumption by goats Mixteca region in the two groups managed in the study (A, B) multinutritional blocks, the group B showed 20% higher in group A, in terms of popularity and taste when consumed consistently in 8 days allocated for consumption, this was quantified on the weight of the debris left by withdrawing the goats of the place assigned to the block for consumption during grazing
Summary
The tropical regions of Mexico, held 36.8% of the national inventory of sheep and in a smaller percentage goats inventory, the predominant production system is extensive or traditional, where the diet of the animals depends on grazing and browsing native species of trees and shrubs, whose nutritional value decreases rapidly with maturity; and during the dry season, food is very nutritious usable [1].In this system, the caprines are kept in good state only 5 or 6 months of the year, retarding their growth and reproductive efficiency in the dry season; to counteract seasonal variations in forage availability is administered as a supplement block [2].When supplementing molasses in multinutritional blocks represents an alternative for easy use by small farmers, in addition to several regional ingredients, it can be used in the manufacture of the blocks. Multinutrient bloc is a dietary supplement rich in nitrogen, energy and generally in minerals, occurring as a solid mass that cannot be consumed in large quantities by its hardness, due to a cementitious material that is added in its preparation.
