What your sheep bloods are telling you
Clinical biochemistry and haematology can be useful in farm animal practice, not only for diagnostic purposes in individual animals, but also routine flock investigations and monitoring. For example albumin and globulin levels can serve as a relatively cheap screen in the investigation of ill-thrift and chronic disease processes, as well as the assessment of colostrum intakes. Assessment of liver enzymes can prove helpful in screening for subclinical liver damage in the early stages of chronic copper toxicity. Assessment of the extent and severity of metabolic disease is essential for the prevention of diseases, especially in sheep in late pregnancy. Blood samples taken 3 - 4 weeks prior to the start of lambing can be used to assess energy and protein status prelambing, helping to reduce perinatal lamb mortality and ewe metabolic disease.
- 1) Choose appropriate biochemistry and haematology tests in sheep
- 2) Interpret clinical biochemistry results in sheep
- 2) Justify use of specific biochemical parameters for the investigation of ill-thrift in ewes and lambs
- 4) Formulate a nutritional monitoring plan for sheep in late pregnancy using metabolic profile blood testing
