The paper starts with a description of parasites of small ruminants in the Philippines. It then discusses host-parasite relationships and worm control options; looks into worm control programs; and examines impact of helminths on production. It then discusses anthelmintic plants and biological co...

The purpose of this chapter is two-fold. First, the information available on breeds of sheep and goats that are resistant or resilient to helminthiasis (mainly the GI nematodes) infections are reviewed. This is important information for inclusion of appropriate breeds in integrated endoparasite c...

The CIAT/CIRAD collaborative project aims to use recurrent selection to create and improve populations and gene pools containing the male-sterile gene and, from this, to develop improved lines and progenitors with traits needed by national programs. This study was to improve germplasm resistant t...

We studied and characterized populations PCT-4 and PCT-7 and gene pool GPIRAT-10 at the Instituto de Investigación del Arroz at rice experiment station, situated south of Jíbaro in the Province of Sancti Spíritus, Cuba, between the 1996 wet season and the 1999 dry season. We aimed not only to cha...

The focus of this volume is on small ruminant production, the effects that nematode parasites have on their productivity and ways of overcoming these effects. In some chapters, avoidance takes on more significance than direct confrontation. This volume is arranged in two sections. The first secti...
