Efecto de sistemas silvopastoriles en la producción y composición de la leche bajo condiciones del valle medio del río Sinú, Colombia

ABSTRACT: The aim of this study was evaluated the effect of three silvopastoral models in production and compositional quality of milk, compared with a treeless prairie. Animals were used from a cross RHC with an average weight of 436 ± 64.2 kg and 56 ± 28 days in milk. The animals were subjected to a daily routine of milking in which production was recorded and samples were taken for analysis of compositional quality of milk. The results indicated no treatment effect on dry matter production (p> 0.05), contrary to this, the treatment effect was recorded in the percentage of PC for the grass Panicum maximum, indicating that with increasing tree cover increased to 12.6% PC, bought with 10% in the treatment without trees. There were no significant differences (p> 0.05) between treatments for Wood model parameters, and time to peak production at peak production, but appeared significant (p<0.05) in milk production per ha, indicating that treatment silvopastoral including shrubs, recorded the highest milk yield ha-1 day-1 with a value of 12.8 l. No significant effect of treatment on milk compositional quality assessed. The results indicated that the model that includes shrubs silvopastoral resulted in increased efficiency of production capacity per unit area, which was influenced by increased forage production and higher load capacity.
