Effect of Supplementing Fresh and Ensiled Cratylia argentea cv. Veraniega on Milk Production of Dual-Purpose Cows in the Subhumid Tropics of Costa Rica Marco Lobo and Vidal Acuña MAG, Costa Rica This study aims to evaluate the effect of the shrub legume Cratylia argentea cv. Veraniega, on milk production when offered as fresh forage or ensiled to dual-purpose cows. Materials and Methods Trials were carried out on two farms located in Costa Rica’s subhumid tropical Central Pacific region, between 0 and 250 masl, and well-defined dry (December-April) and rainy (May-November) seasons. The average temperature is 26 °C and the average annual precipitation is 2,500 mm. Experiment 1. Six cows of third parturition and in second month of lactation were selected from a herd of 45 milking cows that presented broad genetic variation, on a farm located in Barbudal de Barranca, Miramar. Cows produced, on average, 5.5 kg milk/day. After a 12-day period of adjustment to the new diets, each animal was offered the forage supplement for 3 hours/day after milking. The trial lasted 30 days, during which 6 animals were rotated per treatment over a 10-day period, which was divided into 7 days of adjustment and 3 days for individual measurement of milk production per cow. Milk quality, especially in terms of fat and total solids contents, was determined. The treatments evaluated were as follows: T1, check animals grazing the pasture alone; T2, supplement of 12 kg sugarcane, 8 kg C. argentea, 0.6 kg semolina, and 0.5 kg molasses; and T3, 12 kg sugarcane, 3 kg chicken manure, 0.6 kg semolina, and 0.5 kg molasses. The plants of C. argentea used had approximately 4 months regrowth, with an average nutritive value of 16% CP and 33% DM. A Latin square design was used in a changeover system (Lucas, 1983), with three treatments and two animals per treatment. The separation of averages was performed by the Waller-Duncan test (Steel and Torrie, 1988). 61
