Efectos de algunos parámetros productivos, técnicos y administrativos sobre la calidad composicional de la leche en hatos Antioqueños

Abstract

El objetivo de esta investigación fue determinar algunos parámetros productivos, nutricionales y de manejo que afectan la calidad composicional de la leche en hatos lecheros de Antioquia. La investigación se realizó en 14 hatos del departamento de Antioquia en los cuales predomina el pasto kikuyo (Pennisetum Clandestinum) está compuesta por información productiva, reproductiva y de calidad composicional de la leche con un total de 2289 registros. Se realizaron dos etapas en la primera de ellas permitió caracterizar los hatos para conocer algunos elementos de manejo técnico y administrativo y en la segunda se establecieron posibles asociaciones ente parámetros técnicos y administrativos con características de producción y calidad composicional de la leche. Se halló que la franja de pastoreo en un dia tuvo una media de 39.1 ± 17.7

Abstract: the objective of this research was to identify the production, technical and administrative parameters that impact the compositional quality of milk produced on dairy farms in Antioquia. The dairy industry has one of the biggest shares on the economy of the region, and it is the source of most of the rural employment. In this area the milk production is based on pasture, which forces the use of fertilizers and food supplemental in order to improve efficiency and productivity. Tools and methods: The research was conducted in fourteen (14) herds located in Antioquia, most of them sown with kikuyu grass (Pennisetum Clandestinum), we collected 2289 records that include production, reproduction and milk composition quality data. This data was gathered on a year term with samples collected monthly. A model to analyze the impact associated to each fact was improved with the figures gathered. This model a uses the relationship between handling variables and production facts (PDLT, PROT, GLT, KGPROT and KGGRA) to analyze the impact related to each fact, taking in to account a wide range of variables. It was found that the strip grazing in a day had an average of 39.1 ± 17.7 m 2 / cow, total animal
