Abstract

Widespread anthelmintic resistance in small ruminants has necessitated alternative means of gastrointestinal nematode (GIN) control. The objective was to determine the effectiveness of copper oxide wire particles (COWP) administered as a gelatin capsule or in a feed supplement to control GIN in goats. In four separate experiments, peri-parturient does (n=36), yearling does (n=25), weaned kids (n=72), and yearling bucks (n=16) were randomly assigned to remain untreated or administered 2g COWP in a capsule (in Experiments 1, 2, and 3) or feed supplement (all experiments). Feces and blood were collected every 7 days between Days 0 and 21 (older goats) or Day 42 (kids) for fecal egg counts (FEC) and blood packed cell volume (PCV) analyses. A peri-parturient rise in FEC was evident in the untreated does, but not the COWP-treated does (COWP x date, P<0.02). In yearling does, FEC of the COWP-treated does tended to be lower than the untreated (COWP, P<0.02). FEC of COWP-treated kids were reduced compared with untreated kids (COWP x date, P<0.001). FEC of treated and untreated bucks were similar, but Haemonchus contortus was not the predominant nematode in these goats. However, total worms were reduced in COWP-fed bucks (P<0.03). In sum...Continue Reading

Anthelmintics

Anthelmintics or antihelminthics are a group of antiparasitic drugs that expel parasitic worms (helminths) and other internal parasites from the body by either stunning or killing them and without causing significant damage to the host. Discover the latest research on anthelmintics here.

Anemia

Anemia develops when your blood lacks enough healthy red blood cells. Anemia of inflammation (AI, also called anemia of chronic disease) is a common, typically normocytic, normochromic anemia that is caused by an underlying inflammatory disease. Here is the latest research on anemia.
