 | Abstract 411Comparative evaluation of grasses for milk production. I. Bermuda grass cv. Coastcross 1, Bermuda grass cv. Callie and Guinea grass cv. SIH-127.Lamela,-L; Pereira,-E; Silva,-O Estacion Experimental de Pastos y Forrajes "Indio Hatuey", Perico, Matanzas, Cuba. Pastos-y-Forrajes. 1984, 7: 3, 395-408; 13 ref. In experiments in Cuba, Cynodon dactylon cv. Coastcross 1 and Callie and Panicum maximum cv. SIH-127 pastures were grazed rotationally over a 3-year period at a stocking rate of 3 cows/ha. Within each pasture, paddocks were rested for 15 and 20 days in the wet and dry seasons, resp. Data on the chemical composition and yield of the forages in both seasons and botanical composition of the pastures are presented. Daily milk production/cow was highest with cv. SIH-127 (9.5-10.1 kg) and lowest with cv. Coastcross 1 (8.5-9.3 kg), but no differences were detected in milk composition. DM availability decreased with grazing for both C. dactylon cv. but increased for cv. SIH-127. It was concluded that P. maximum cv. SIH-127 showed the greatest potential on the basis of milk yield, DM availability and persistence. This abstract relates to the following species: |
