Efecto del uso de bioles elaborados a base de suero y microorganismos benéficos nativos (MB) sobre la calidad de la leche

Abstract

This research was conducted to evalue the effect of biols made from whey and native beneficial microorganisms (BMOs) on the quality and composition of milk; it was performed on two farms at different altitudes: Hacienda Guandug (A) and Hacienda Rosa de Oro (B). In each one, 20 Holstein female cattle were grouped into two sets of 10 animals, selected according to their stage of lactation (one-third) and the number of calving. Treatments to be evaluated wew T0 (Control) and T1 (Biols supplementation) crossed in a 2X2 design, with the effect of each Hacienda (A and B). The variables evaluated were: altitude above sea level, milk composition (somatic cell count, fat, protein, lactose, non-fat solids, total solids, salts, density, and pH of milk), and the pH of bovine feces. The results obtained in the study showed that, with the inclusión of biols in cattle feed, there are changes in the levels of lactose and total solids. However, the somatic cells count, fat protein, non-fat solids, salts, and the Ph of the cow¬¬¬'s feces were not affected. In conclusion, the inclusión of non-fat solids in milk regardless of tge geographical location. Nevertheless, further study of the activity of BMOs in rumiants is required to support their effectiveness. Keywords: yeast, cattle, eficient microorganisms, milk composition
