Thirty-four sheep were infected with nematode parasites ( Trichostrongylus spp. and Ostertagia circumcincta ) during central incisor formation. The tooth enamel was examined for defects of mineralization at eruption and compared with that of 14 contr

The hypothesis that diffuse opacities in enamel result from a chronic, mild disturbance to ameloblast activities was tested using fluoride. Three sheep (HF) were dosed orally with 0.5, and 3 (LF) with 0.2 mg fluoride/kg body weight daily for 6 months

Thirteen young pigs from a minimal disease herd were infected with 4,000 larvae of Hyostrongylus rubidus and killed at intervals. The stomachs were examined for evidence of pathological changes. Worms were recovered and examined to determine the stag
