EQUINE | Equine Disease Update mid-1960s, it was suggested that horses should be de- wormed for strongyles every six to eight weeks. This frequent deworming was thought 1) not to provide time needed for Strongylus spp. to mature, 2) to help decrease potential cyathostome egg deposition on pas- tures, and 3) not to allow time for ascarids to mature High strongyle fecal egg counts indicate contamination of pastures and increased potential for ingestion of in- fective larvae by grazing horses. Thus, profiling the num- ber of eggs per gram (EPG) of feces has been used in up- dating deworming 66VGVW266R7G&wW27&Pr&&VǒV6VFW&VBFWv&֖r66VGVR6&P&RfW&RVf'GVFVǒFW&R2F&V7B&VFЧ6&WGvVVUrfVW2B7F7FRV&W'27VvvW7FVBFWv&֖r&w&22fw3( "W7F&Ɨ67G&wRUr&fRf"FfGV'6W0&FW"FFWv&֖r'6W37GVGb@F&Vv'&VB&W26vVBFBRfV66ЧƖrW"'6Rv27Vff6VBf"W7F&Ɨ6r7G&ЦwRUr&fR( "f"7G&wW2W6RfW&V7F"FV7FP"6&FvF&VFVGv6RV.( @66FW"G&VFrFR7&rBfvR&VЦ֖FW2B&FV&RVffV7FfR7ЧF7FW2FW&RVff66W2G&VFrFW &6FR7V6W2( "G&VBf2WfW'VvBvVV2bvRf"66&BЦfV7FVFFW&V6RV&Ɩw3&VFR07W'&VFǒ66FW&VBFRG'Vrb66RfvVB'fV&VFR( "6G&7G&wFW2vFfW&V7F"&VFЧRBFWv&2vF&VFV"&FVFRF'G&FRv6fWpFRWF'&Vb6&Ff&6VFF2VGV6( 0#f7&v266W&rFFRWVRGW7G'vRB2&vR66R26VV#vR&R6VRЦr&R66W2bFRF6V6RFR#rf7&शVGV6FFR7B6WfW&V'2fwW&R6&Ff&6VFF2v2f'7BFVFfVBB6"Ц7FW&VBFR֖B26WVV6rbFR6W6FfPvVG2VBFFRFW&( 6&Ff&( GVRFFRЦvV2&VFVFW72bF2&vRf֖ǒb&7FW&FP7B6&v62fR&VVFVFfVB2f&ЦW2ז6F62B7G&WFז6W27B7&76ЦVWVWF6W2g&6&Ff&6VFF26&vRg&&'FFVƗfW'bvV'WBf&Rf2"FVƗfW'b&f3WF6W2&RFWVFV@WFR6WfW&GbFR6VFF26R66W2f0&RBf&RB&RWWF旦VB#GVRF7V"Ч6FW2Bf"6VF7V&֗762BW֖FFR&W76Rg&FR6WVRGW7G'v2W6WЧFBFRTdDvFW76VBFR&vW7BV&W"`6&Ff&6VFF266W27V&֗GFVB&V6&BFPvBWw2v2FBsW&6VBbFR#66W2&RЧ7VFVBf&Rf266W&2b7&V6VB6FV6R`6&Ff&6VFF2FR#rf7&7W&f6V@6F7CRBǖ2BVǖ3VVGRS#УRvVvV6WVR&W6V&66VFW"VfW"Ч6GbVGV6WwF6&Ff&6VFF2g&WFV֖Ю( "fVR"( "VR#r( #
