RESEARCH RESULTS Component 2: Developing New Feeding Systems for Dual-Purpose Cattle Activity 2.1. On-farm evaluation of different forage systems for beef cattle in dual-purpose systems Highlights • Forage-based feeding systems for strategic supplementation during the dry season reduce the need to purchase animal feed concentrates and increase the income in dual-purpose farms. • The use of legumes with an energy source during the dry season maintains milk production. 48
Milk Production in Dual-Purpose Cows Grazing Pastures of Brachiaria brizantha cv. La Libertad Alone and Associated with Arachis pintoi cv. El Porvenir in the Subhumid Tropics of Costa Rica Marco Lobo and Vidal Acuña MAG, Costa Rica Costa Rica has a land area of 51,023 km 2 , of which 25,100 km 2 (49.2%) are under agricultural and livestock exploitation according to the 1984 National Agricultural and Livestock Census. Of the area under cultivation, grasses occupy the largest proportion—16,500 km 2 , in other words, 65.7%. Beef cattle are raised on 51,000 farms; their population is estimated at 2,150,000 heads of cattle, of which 75% have been crossbred, at different levels, with Zebu breeds. Among the main problems affecting beef cattle development in Costa Rica are low meat and milk productivity, low reproductive rates, nutritional deficiencies (especially because of the low forage availability and quality during the dry season), and health problems. Forage is the most available and inexpensive source of feed for livestock in Costa Rica; however, a high percentage of pastures are now degraded, reducing forage availability and quality. The improvement of both the quality and quantity of forage resources through the recovery of degraded pastures is important to increase overall livestock productivity. The study aims to evaluate milk production of dualpurpose cows grazing a recovered pasture of Brachiaria brizantha cv. La Libertad alone and associated with Arachis pintoi cv. El Porvenir and Centrosema brasilianum. Materials and Methods The trial was carried out on a farm located in San Jerónimo de Esparza, in the subhumid tropical central Pacific region of Costa Rica, at an average altitude of 250 masl. The region is characterized by having well-defined dry (December-May) and rainy (June-November) seasons, with an average annual precipitation of 2,500 mm. Four hectares of Brachiaria brizantha cv. La Libertad were planted in a paddock where a degraded pasture of Brachiaria ruziziensis existed. The area was divided in half and 2 ha were 49
