Caracterización y efecto de bioensilaje en la producción y calidad de la leche bovina.

Abstract

The investigation had as objective to characterize and to validate the technology of bioensilaje production starting from the residuals of crop of corn, elaborated with different simbióticos with the help of serum of milk, bovine manure and the combination of the same ones, for then to be used in the feeding of cows Holstein, to increase the production of milk and quality of the same one. To such an end the experimental scientific method was used where the treatments were distributed totally at random under a design on the experimental units, the same ones that were managed by means of direct shepherding and silage supply to reason of 2 Kg/día, during 150 days of experimentation. The obtained results when concluding the experiment, demonstrate that the biggest lactic acid production and nitrogen true, as well as smaller acetic acid content and ammoniacal nitrogen in the bioensilaje of residuals of corn with the help of simbióticos of Serum of Milk, being also reported respectively bigger content of gross protein and fat with 16,69 and 1,77%, as well as smaller fiber content with 20,31%. On the other hand with the use of this bioensilaje in Cows Milkmaids the best gain of weight was obtained reaching a value of 5,46 Kg, bigger production of milk with 8,75/vaca/día and more efficient nutritious conversion, being also obtained a bigger protein content and fat in the milk with 3,50 and 4,12% in its order, with the same treatment a bigger profitability was obtained reaching an indicator of beneficio/costo of 1,22 USD. Being concluded that the cows tried with bioensilaje of residuals of corn with the help of simbióticos of Serum of Milk, obtained the best parameters productive and better chemical characteristics in the produced milk, as a result of a better silage quality. For the previously exposed thing, bioensilaje of residuals of corn is recommended with the help of simbióticos of Serum of Milk, in the diet of cows Holstein, since presented the best results presently study.
