  1. Efficacy of Newbouldialaevis Extract and Nutrient Density on Gastrointestinal Nematode In Sheep Managed Semi-Intensively O. S. Sowande, S. O. Iposu, O. A. Sonibare, A. O. Oni, J. A. Olanite and A. O. Yusuf

  2. Introduction • Infection with gastro-intestinal nematodes is major constraint to sheep production in Nigeria and elsewhere. • Increase resistance of gastrointestinal parasite to conventional anthelmintics caused economic loses. • Suggested alternatives are: • biological control, grazing management (Marley et al., 2006) • vaccination (Hein and Harrison, 2005) • nutritional management (Hosteet al., 2005; Iposuet al., 2008) • genetic control (Grilloet al., 2007) • Plant extracts (Hounzangbe- Adoteetal., 2005)

  3. Objectives • To determine: • the effect of oral administration of extracts from N. laevison performance, faecal parasite egg counts in semi-intensively managed sheep. • the effect of nutrient density on performance and faecal parasite egg counts in semi-intensively managed sheep. • the effect interaction of oral administration of extracts from N. laevisand nutrient density on performance and faecal parasite egg counts in semi-intensively managed sheep.

  4. Materials and Methods • Leaves of matured Newbouldialaevis(Border tree) were collected, air dried, crushed and extracted with 70% ethanol. • Newbouldialaevis extract was administered at 0, 30 and 60mg/BW. • Concentrate supplement were Low Energy, Low Protein(7.71 ME/KJ and 75.8g/kg CP) and High Energy, High Protein (13.24 ME/KJ and 176.3g/kg CP). • 24 WAD rams aged 12 - 15 months were used. • Grazing of Stylosantheshamata,Pennisetumpedisellatumand natural pasture was allowed 6hrs/day • Data was collected on concentrate DMI, weight changes, faecal egg count, PCV, WBC, RBC, Hb, glucose, total protein, alaninetransaminase (ALT) and aspartatetransaminase (AST). • Data was arranged as a 2 x 3 factorial format in a completely randomized design.

  6. Conclusion • Grazing sheep should be supplemented with high energy- high protein concentrate diet and drenched with 60mg/BW Newbouldialaevis extract monthly for improved performance and reduction of worm burden.
