EVALUATION OF Brachiaria Humidícola (CIAT 6369) UNDER PASTURING IN CONDITION OF GUALACA, PANAMA.
With the purpose of knowing aspects of production of meat and productivity, it was evaluated the promissory pasture Brachiaria humidicola CIAT 6369 during two years (1988-90), in the Gualaca Experimental Agricultural Station, under condition of acid and no fertile soil and about four months of drought. The management of pasturing was rotary of 10 days of pasturing and 30 rest days in four grazing field of 0.50 ha each. The pasture was fertilized with 75-40-30 kg of N, P2O2 and K2O, respectively. The animal load was the same during the dry season (four animals/ha) and during the rainy season was variable (4-6 animals/ha) with arrangements according to availability. Commercial Zebu animals of 200 kg were used and were, only fed with mineral salt. The average results of two years showed gain of average weight of 0.420 kg/animals/day during the rainy season and 0.125 kg/animals/day during the dry season. The animal load during the rainy season was of 4.9 animals/ha of 3.6 U.A./ha, and during the dry season was from 4.0 animals/ha to 2.0 U.A./ha. The meat production was of 555.6 and 22.7 kg/ha to the rainy and dry seasons, respectively, for a total of 578.3 of meat/ha/year. The available and residual forage was 1183.5 and 692 kg MVS/ha/cycle and the growth rate of 19.3 kg MVS/ha/day. The estimated pasturing pressure was of 2.34 kg MVS/100 kg of alive weight. The content of brute protein was from 4.7 to 8.4% during the rainy season and the digestibility was from 56.0 to 58.0%; during the dry season the brute protein was from 3.9 to 6.3% and the digestibility was of 52.5%. Under the conditions of this study, the B. humidicola CIAT 6369 showed low productivity in terms of daily weight gain per animal and production per unit of surface in comparison to other Brachiarias in Panama, so that the gramineous seems to tolerate high and showed a tendency to degrade in form of grass, although it kept a good coveraged, drastically reduced the availability of forage with the pasturing, wich was not been previously presented under cut. Due to the lost of productivity, it was not recommendable the propagation of this gramineous at farm level with soil and climate conditions similar to this research.
