Description
Pastures of Digitaria decumbens (Dd) and Cynodon nlemfuensis (Cn) were each grazed by 64 native suckling ewes ( 40 ewes/ha) in Martinique. Forage characteristics, ewe feeding behaviour and lamb growth were studied. The available herbage mass (kg DMJLW0-75/day) was lower for the Dd pastures than for the Cn pastures: 295 v. 355 for the leaves (P<0.05) and 820 v, 1360 for the stems (P<0.01), respectively. There was no difference in the diurnal activities (grazing, ruminating) between the ewes in the 2 groups. Number of bites/min was higher on Dd pasture than that for Cn: 31 v. 26 (P<0.001), Preweaning daily weight gain (g/day) was higher for the Dd lambs group than for Cn: 170 v. 140 (P<0.01). The lamb mortality rate(%) was respectively: 15 v. 27 (P<0.05). Pasture management problems are discussed.
