Interpretive Summary:

Technical Abstract: The objective was to investigate the interaction between high protein supplementation and copper oxide wire particles (COWP) to control gastrointestinal nematodes (GIN) in growing female goats. Haemonchus contortus is the primary GIN during summer months on this farm. In early August 2006, Boer and Spanish x Boer does (193 ± 2 days of age) were assigned randomly in a 2 x 2 factorial design to receive no or 2 g COWP and were supplemented with 220 g corn/SBM (CSB; 14% CP; 9 untreated and 8 COWP-treated does/supplement) or cottonseed meal (CSM; 41% CP; 8 untreated and 9 COWP-treated does/supplement) while grazing two bermudagrass pastures at a stocking rate of 14 does/ha. To minimize differences in forage quality between pastures does were rotated between the two pastures every 7 days. Supplement was withdrawn on Day 42 (Day 0 = day of first COWP administration). A second 2 g bolus of COWP was administered to all kids on Day 42 to assess value as an anthelmintic in does administered no or 2 g COWP previously. Body weight was determined every 28 days and feces and blood collected every 7 days for fecal egg counts (FEC) and blood packed cell volume (PCV) analyses. There was a marked reduction in FEC in COWP-treated goats within 7 days, which remained lower than untreated does until Day 21 in CSB does and Day 28 in CSM does (COWP x day, P<0.001; supplement x day, P<0.08). PCV tended to increase in COWP-treated compared with untreated does (P<0.08). All goats responded similarly to COWP administered on Day 42 with a 79% reduction in FEC from previous week. FEC of Spanish x Boer crossbred goats were lower (834 ± 198 < 1437 ± 269 eggs/g; P<0.04) and PCV higher (27.0 ± 0.3 < 25.1 ± 0.4%; P<0.002) compared with Boer goats. Body weight was similar among treatment groups throughout experiment (Day 0: 21.2 ± 0.5 kg; Day 49: 28.8 ± 0.5 kg). There was no advantage to supplementation with CSM compared with CSB for reduction of GIN. COWP was effective in control of existing GIN infection in both supplementation groups.
