Production responses of lactating dairy cows and heifers given thiabendazole at parturition.

A field trial was conducted to examine the effects on productivity of dairy cattle in 6 herds given thiabendazole at parturition. Criteria examined were milk and fat production, calving interval, services per conception, culling rate, and (in a subset of cows) hematologic response. Analysis of the data for all cows as a group did not indicate a significant effect. For first-calf heifers in 1 herd, a significant (P less than 0.01) and economically important increase in milk production was observed; why the effect was seen was not determined.

Economic decisions in food animal practice: to treat or not to treat?

The food animal practitioner is faced repeatedly with the dilemma of whether to intervene with treatment or to recommend sale of an animal for salvage value. An algorithm is presented that allows a clinician to choose between intervention or sale for salvage value in cases where the economics of the decision are not obvious. The algorithm allows an objective evaluation of the economic factors that are pertinent to such a decision. These factors are the cost of intervention, the salvage value of the animal, and the prognosis for a favorable outcome following intervention. A graphic approach has also been derived which allows rapid interpretation of the algorithm in field situations.

A field evaluation of benzimidazole and nonbenzimidazole drugs in a herd of dairy goats.

A study was conducted to investigate the efficacy of six anthelmintics in a herd of dairy goats. Pretreatment larval cultures indicated that the goats were infected with Haemonchus contortus and Trichostrongylus colubriformis. Three separate treatment regimens were administered. In each trial, mature nonlactating goats were allocated into two treatment groups and a control group. Treatment groups received thiabendazole (TBZ) or levamisole (LEV), mebendazole (MBZ) or fenbendazole (FBZ), and morantel tartrate (MOR) or ivermectin (IVR). LEV, MOR, and IVR reduced fecal strongyle egg counts by 99% to 100% of pretreatment values. The benzimidazole (BZD) drugs changed pretreatment fecal egg counts by +2% to -32%. Results of posttreatment larval culture demonstrated the presence of H contortus larvae following the administration of BZD drugs.
