“…The sciatic nerve runs through the hindlimb, the largest nerve in the body 32 . Vaccinating the wrong location in dairy cow cadavers strayed sufficiently close to the sciatic nerve to risk damage, which, in live animals, would cause pain, nerve function compromise and limb paralysis 18 . What is not clear is whether individuals would stray close to these structures in sheep, as there is no comparative study.…”

“…[15][16][17] Poor vaccination techniques in cattle are linked to iatrogenic sciatic nerve damage when injected into the gluteal muscle. 18 Further work is needed to confirm whether hindlimb IM injection in sheep may cause similar iatrogenic nerve damage based on injection site location.…”

Surveying UK sheep farmers’ vaccination techniques and the impact of vaccination training

Background Vaccines are commonly used in sheep farming. However, compliance with vaccination protocols and subsequent suboptimal vaccination techniques are concerns in the industry. Methods An online survey containing 31 questions encompassing vaccination storage, technique and training was distributed to UK sheep farmers. Respondents were asked to mark on a sheep diagram where they would administer intramuscular (IM), intradermal, and subcutaneous (SC) vaccines. Results Of 370 respondents, only 26.1% identified the correct location for SC, 38.0% for intradermal, and 7.7% for IM vaccination. Almost half (45.5%) stored their vaccines in a fridge specific to veterinary medicines, only 33.9% used a temperature logger, and 6.4% checked their fridge temperature daily. Almost half (45.5%) kept their vaccines 48 hours or longer after broaching, and 11.1% kept them until the next time. Significantly more respondents who had received training correctly identified the location for IM vaccination (p < 0.01). However, training had no significant influence on the the correct identification of the other vaccination sites, vaccine storage or administration. Conclusion Suboptimal vaccination techniques are not due to unwillingness to learn; 83.8% responded that they would consider taking a course to improve their use. However, the majority (73.9%) were unaware of the training courses available. Therefore, the industry needs to respond and promote courses.

Iatrogenic diseases in veterinary medicine are often related to malpractice or lack of skill. For this retrospective study, 4262 clinical records of cattle admitted to the veterinary teaching hospital of the University of Milan between 2005 and 2017 were analysed, and 121 cases (2.8 per cent), referred for an iatrogenic-related disease, were selected. The findings showed that iatrogenic diseases were more often caused by farmers (92.6per cent) than by bovine practitioners (7.4 per cent). Iatrogenic diseases were caused mainly by the improper administration of drugs (43.0 per cent), forced extraction during calving (19.8 per cent), forced milk or colostrum feeding, which was often performed by awkward administration using a nipple bottle (14.9 per cent) or by oral oesophageal tubing (15.7 per cent). Moreover, farmers often performed medical, nursing and zootechnical procedures without adequate training. The role of the practitioner is fundamental in farmer education. Clinicians, especially in some professional branches such as neonatology, should not delegate medical procedures to untrained farmers. Effective tutoring and good communication with farmers play a key role in dairy herd health and consequently in public health. This then can lead to a decrease in improper drug administration, the prevention of antibiotic resistance and the reduction of treatment costs.

“…In dairy systems, injections are often performed in the milking parlour and are given in the gluteal region but caution should be taken when injecting in this site to avoid damaging the sciatic nerve. Where safety permits and where no injection site is specified, the neck region is always preferable (Kirkwood and others 2018) and appropriate handling systems such as races and feed barriers with self‐locking head yokes can help to facilitate this.…”

Veterinary medicines that are stored on the majority of UK farms include antimicrobials, anthelmintics, non-steroidal anti-inflammatory drugs and vaccines. All prescription veterinary medicines have storage requirements as directed on the datasheet or summary of product characteristics (SPC) and there are also specific instructions for how, when and where medicines should be administered. Vaccines often have storage and handling instructions on the SPC in addition to those applied to other medications; most also require maintenance of the ‘cold chain’ consistently between 2 and 8°C and have short shelf lives (usually hours) once bottles have been broached. This article highlights areas where the on-farm handling and storage of medicines (particularly vaccines) could be improved and provides suggestions for how veterinary practices can support clients to ensure that medicines are used to their maximum benefit.
