Recent discoveries that high prolificacy in sheep carrying the Booroola gene (FecB) is the result of a mutation in the BMPIB receptor and high prolificacy in Inverdale sheep (FecXI) is the result of a mutation in the BMP15 oocyte-derived growth factor gene have allowed direct marker tests to be d...
In the Philippines, management of grazing flock like rotational grazing is not being done as a parasite control, but to improve the condition of the pasture and the nutritional status of the animals. Posas (1981) compared goat production and impact of soil, pasture, and coconut production. Rotati...
There have been numerous Reports of resistance to anthelmintics in Southeast Asia, from Malaysia (Rahman, 1994), Thailand (Kochapakdee et al., 1995) and Indonesia (Dorny et al., 1995). In the Philippines, benzimidazole resistance in a field population of Haemonchus contortus from sheep has been d...
Presents the objective of the programme, viz., to implement currently available options for nematode control including rotational grazing systems and identification of effective dewormers. Preliminary results on these are presented here. Research on the identification of resistants genotypes is i...
One of the alternative control strategies being advocated by scientists and goats raisers is the identification of breeds of goats that are resistant specifically to endoparasites that commonly affect existing breeds and exotic genotypes. Due to the Reported large genetic variation existing among...
The effectiveness of protein supplementation and genetic selection to enhance the resistance of periparturient Merino ewes to infection from gastrointestinal parasites was tested in a replicated grazing experiment. One hundred and twenty ewes from lines selected for increased resistance (R) to Ha...
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...
