title: Effects of management system, legume feeding and anthelmintic treatment on the performance of lambs in north Sumatra.
abstract: Sixty-four lambs in North Sumatra were used in a factorial experiment comprising two systems of management (grazing and stall-feeding), four levels of legume supplementation (0, 250, 500 and 1,000 g/d Pueraria javanica) and two anthelmintic treatments (none and albendazole every four weeks). The experiment lasted five months. The mortality rate for lambs not given anthelmintic was 28%, significantly higher (P less than 0.05) than for animals given anthelmintic which had zero mortality. Anthelmintic treatment increased growth rate from only 2 g/d to 29 g/d (P less than 0.05) and reduced faecal egg count from 1,700 epg to 270 epg. When not given anthelmintic grazing lambs had a higher mortality rate (38%) than stall-fed lambs (19%) but this difference was not significant. When given anthelmintic grazing lambs has a slightly higher growth rate (32 g/d) than stall-fed lambs (26 g/d). System of management had no apparent effect on egg count. Legume supplementation reduced the egg count of lambs not given anthelmintic but had no significant effect on mortality or growth rate.
