A survey of biosecurity-related practices, opinions and communications across dairy farm veterinarians and advisors.

Biosecurity at farm-level can often be poorly implemented, and lack of information has been cited by many studies as a potential explanation. Veterinary practitioners (VPs) and dairy advisors (DAs) play a central role in the provision of animal health and management services to dairy farmers. The objective of this study was to document and compare biosecurity-related practices and opinions across VPs and DAs in Ireland. A selection of veterinary experts (VEs) from outside of Ireland was also surveyed. Questionnaires were completed and response rates of 47% (VPs), 97% (DAs), and 65% (VEs) were achieved. Significant differences were identified in the promotion and implementation of biosecurity between VPs and DAs, with a higher proportion of VPs regularly receiving requests from (P = 0.004), and dispensing advice to (P < 0.0001), their farm clients. Communication between DAs and VPs was sub-optimal with over 60% of each group not in regular communication with each other. With regard to the main farmer motivation for biosecurity implementation, the majority of VPs (62%) prioritised external factors such as 'economic benefit' and 'mandatory obligation', while the majority of DAs prioritised health/animal-related factors (69%), which were similar to those of farmers (83.1%), although they remained significantly less likely (OR = 1.8) than farmers to choose such motivators (P = 0.005). Inconsistencies in the implementation of, and in opinions relating to, farm biosecurity were highlighted across all the groups surveyed emphasising the need for standardised information and improved communication.

Implementing biosecurity measures on dairy farms in Ireland.

Dairy farms in Ireland are expanding in preparation for a new era of unrestricted milk production with the elimination of the European Union (EU) production quotas in 2015. Countries experiencing a changing agricultural demographic, including farm expansion, can benefit from documenting the implementation of on-farm biosecurity. The objectives of this study were to document and describe influences on biosecurity practices and related opinions on dairy farms. A representative response rate of 64% was achieved to a nationwide telesurvey of farmers. A 20% discrepancy was found between self-declared and truly 'closed' herds indicating a lack of understanding of the closed herd concept. Although >72% of farmers surveyed considered biosecurity to be important, 53% stated that a lack of information might prevent them from improving their biosecurity. Logistic regression highlighted regional, age, and farm-size related differences in biosecurity practices and opinions towards its implementation. Farmers in the most dairy cattle dense region were three times more likely to quarantine purchased stock than were their equivalents in regions where dairy production was less intense (P=0.012). Younger farmers in general were over twice as likely as middle-aged farmers to implement biosecurity guidelines (P=0.026). The owners of large enterprises were almost five times more likely to join a voluntary animal health scheme (P=0.003), and were over three times more likely to pay a premium price for health accredited animals (P=0.02) than were those farming small holdings. The baseline data recorded in this survey will form the basis for more detailed sociological and demographic research which will facilitate the targeting of future training of the farming community in biosecurity.
