摘要:

The development of new anthelmintics for use in livestock has been probably the most rapidly expanding area in the field of pharmaceutical research of recent years. Scarcely a month goes by without the reporting of yet another new compound being introduced for its novel anthel-mintic activity.

摘要:

The results of a postal survey which yielded a 43% response on the prevalence, treatment and control of footrot in Central Otago flocks is presented. Analysis of data showed that footrot is an important and emerging disease, particularly of fine-wool flocks, and that most farmers have a poor knowledge and understanding of the epidemiology, treatment and control of the disease.

摘要:

Phosphorus deficiency was diagnosed in a 90 cow seasonal supply dairy herd which showed low milk production, ill-thrift, infertility and osteophagia. Serum inorganic phosphorus and pasture phosphorus levels were low, pasture Ca:P ratios high and soil phosphorus levels very low; the soil phosphate retention value was 96%. The deficiency, which had probably existed for several years, was considered to be due to inadequate annual phosphate fertiliser applications on a high phosphate retaining soil. Phosphorus deficiency may have been exacerbated by the application of lime without phosphate several months before the onset of severe clinical disease. The finding of low sodium levels in pasture samples suggested that sodium deficiency may have co-existed and contributed to the clinical picture.

摘要:

Groups of four stag fawns, weighing 51 ± 0.8 kg, were infected with 30,000 larvae of one of three nematode parasites:O. circumcincta, O. ostertagia, orH.contortus. A further four remained as control. Individual feed intake, body-weight, faecal egg count and plasma pepsinogen concentration were measured during seven weeks after infection.
