Descripción de los parámetros productivos, reproductivos y de las tecnologías de producción en sistemas intensivos de ganadería bovina en el sur del Valle geográfico del río Cauca
The study was carried out in the plain zone of the south of Cauca Valley, Colombia. The main productive and reproductive parameters and the more representative technological characteristics were estimated and analized comparatively for nine (9) farms, classified as intensive cattle production systems. The results were (means and confidence intervals): a) Production parameters: Cattle units/ha: 2.7 (2.5-2.8); animal/ha: 3.2 (3.0-3.4); lactation length, days: 320 (292-349); daily milk production per cow, 1:8.1 (6.4-9.8); productive cows, % 74.3: 64.2-84.4) Yearly milk production per cow, 1: 2850 (2231-3370); herd cow - day production, 1: 5.75 (4.2 -7.3). b) Reproduction parameters: birth rate, %: 80.5 (71.6-89.5); parity intervals, months: 14.7 (13.7-15.9); parturition-conception intervals, days: 166 (129-202); matings per conception (Al): 1.7 (1.3-2.1); age at first mate, months: 23 (20.6-25.3). That analyzed farms have parameters, which were above that expected for intensive cattle productive systems in Colombia. Farms showed a high degree of intensification linked to the utilization of technologies suitables to the system, such as the use of: improved breeds, improved pastures, chemical fertilizers, agrotoxics, irrigation, intensive rotation of pastures, concentrate feeds, forage conservation (silage and hay), vaccines, deworming drugs, artificial rearing and insemination, milking parlor equipment. However is not common the use of technologies for the utilization of crop residues, agroindustry by products, legumes associated with grasses or foliage legumes.
