GOMEZ-VEGA, Sergio; CAICEDO-PINZON, Ronald y VARGAS-MARTINEZ, Juan. Strategic supplementation effect in a dairy system in Cundinamarca, Colombia. Rev. investig. vet. Perú [online]. 2019, vol.30, n.3, pp.1109-1116. ISSN 1609-9117. http://dx.doi.org/10.15381/rivep.v30i3.15302.
The aim of this study was to evaluate the effect of strategic supplementation on the productive and economic response of a dairy system in Cundinamarca, Colombia. Six lactating cows were selected. Animals were 455 ± 65 kg body weight, 100 ± 4.94 days in milk and 10 ± 0.2 L of daily milk production. Cows were randomly distributed in two supplementation schemes: commercial (forage + commercial supplement) and strategic (forage + strategic supplement). Dairy production and composition, feed intake and body condition were determined during three periods of 20 days each. In addition, production costs and economic indicators were determined. The productive variables were analyzed through a switch back model, while the economic ones through randomized complete blocks. The results suggest that strategic supplementation did not modify feed intake, milk production, milk composition, or economic indicators. However, the costs of the supplement decreased by 37.5%. In conclusion, the strategic supplementation would reduce feed costs without affecting productive parameters in a dairy production system.
