This technique can be used with all strains and for single and repeat samples. Use of the artery is normally used for larger volume samples or for arterial blood, but carries a greater risk of haematoma and bruising (Diehl et al., 2001).
Local anaesthetic cream (e.g. EMLA cream) can be applied to the site 30 minutes prior to blood sampling. The technique should be carried out aseptically and the dorsal surface of the ear should be shaved or clipped.
The rabbit should be restrained in sternal recumbency and the ear held out by the assistant (Brown, (2016)).
Blood is taken from the tip of the ear, away from the base of the ear. Serial blood samples can be taken by moving towards the base of the ear on the same vein and by alternating ears. The ear should be warmed in order to dilate the vessel. This can be done by gently stroking; it should not be necessary to use a heat lamp. The technique should be carried out aseptically and the dorsal surface of the ear should be shaved or clipped.
HORSE
The most suitable vein to take blood from in the horse is the jugular vein, this is because it has a good blood supply, very accessible and other veins such as the saphenous would be too dangerous to take blood from for a routine …show more content…
MUST FIND OUT WHY THIS VEIN IS USED
The animal is put into a crush. Raise the tail vertically with one hand until it is horizontal with the ground and wipe the underside of the tail to remove any manure present. The tail is then held in one hand such that the ventral surface is accessible. The ventral surface of the tail is cleaned with a swab to remove faecal material. A needle is then inserted perpendicular to the skin surface on the midline between (approximately) the third and fourth coccygeal vertebrae, (Zubair Shabbir et al., (2013))

The Packed cell volume or PVC is an estimate of the percentage of cells within the blood (Reeder, (2009)).
Total protein (TP) = A total serum protein test measures the total amount of protein in the blood. It also measures the amounts of two major groups of proteins in the blood: albumin and globulin (WebMD, 2016).
Fibrinogen is a soluble glycoprotein synthesized by the liver. . It is used to diagnose and monitor a variety of inflammatory conditions in the horse (Gerros,
