Veterinary Interventions to Improve Neonatal Survival on British Beef and Sheep Farms: A Qualitative Study

Improving triplet lamb survival: management practices used by commercial farmers

Introduction

Prolificacy has become an important breeding goal in sheep farming to increase farm profitability. With the adoption of improved genetics and management practices leading to increased lambing percentages, the proportion of triplet-born lambs has also increased on farms. However, mortality rates of triplet lambs are higher than for single- and twin-born lambs, and additional management inputs may be needed to support survival. The aim of this study was to identify factors that affect management practices that are considered important for triplet lamb survival by commercial farmers from the United Kingdom (UK), the Ireland (IRE), and New Zealand (NZ).

Methods

An online survey was developed and disseminated to farmers in each country, focusing on farmer demographics, flock characteristics, management practices and production outcomes. A total of 448 farmers completed the survey, from the UK (n = 168), IRE (n = 218), and NZ (n = 62).

Results

Respondents had larger flocks, higher scanning and lambing percentages than the country average for the UK and IRE. The mean percentage of triplet litters born within flocks was 9%, and lambs lost between scanning and lambing were 14% for UK, 15% for IRE, and 25% for NZ respondents (P = 0.063). Overall, 60% of all respondents reported to lamb indoors and 40% lambed outdoors, however NZ farmers almost exclusively lambed outdoors, whereas UK and IRE farmers lambed in both systems (P < 0.001). NZ farmers were more likely to rear all triplet lambs with the ewe, whereas UK and IRE farmers were more likely to remove a lamb to rear by another ewe or artificially (P < 0.001). Factors that influenced triplet lamb management practices of respondents in this study were respondent country of origin, flock size, age, and gender. In general, younger respondents (P < 0.001), and female respondents (P < 0.05), were more likely to engage in management activities that were considered to promote better triplet lamb survival, compared to older and male respondents respectively. These practices were associated with better lamb survival reported by respondents but were less likely to be carried out when flock size increased (P < 0.001).

Discussion

The results of this survey highlight future priorities or communication strategies needed to improve triplet lamb survival.

Access to veterinary care: evaluating working definitions, barriers, and implications for animal welfare

Humans have a moral obligation to meet the physical and mental needs of the animals in their care. This requires access to resources such as veterinary care, which is integral to achieving animal welfare. However, "access" to veterinary care is not always homogenous across communities and currently lacks a consistent definition. The objectives of this scoping review were to (1) understand how "access" to veterinary care has been defined in the literature, (2) map a broad list of potential barriers that may influence access to veterinary care, and (3) identify how access to care impacts the welfare of companion and livestock animals. The literature search yielded a total of 1,044 publications, 77 of which were relevant to our inclusion criteria, and were published between 2002 and 2022. Studies were most frequently conducted in the United States (n = 17) and Canada (n = 11). Publications defining access to veterinary care (n = 10) or discussing its impacts on animal welfare (n = 13) were minimal. However, barriers to accessing veterinary care were thoroughly discussed in the literature (n = 69) and were categorized into ten themes according to common challenges and keywords, with financial limitations (n = 57), geographic location (n = 35), and limited personnel/equipment (n = 32) being the most frequently reported. The results of this scoping review informed our proposed definition of access to veterinary care. Additionally, our findings identified a need to further investigate several understudied barriers relating to access to care (i.e., veterinarian-client relationship, client identity) and to better understand how they potentially affect animal welfare outcomes.

Farmers Views on the Implementation of On-Farm Emergency Slaughter for the Management of Acutely Injured Cattle in Ireland

Four management options for acutely injured cattle in Ireland exist: treatment, unless cattle are severely injured; on-farm emergency slaughter (OFES); casualty slaughter (CS) if the animal is certified fit for transport; or euthanasia. OFES is designed to prevent transport of welfare-compromised cattle. An online survey of farmers in Ireland was carried out between April and July 2021 and focused on events during 2020. A theoretical framework of capacity, willingness, and opportunity was used to explore farmers' perceptions. Responses from 94 farmers (49 dairy and 45 beef) were analysed; not all respondents answered all questions. Respondents indicated that the incidence of acutely injured cattle in Ireland is low. A majority reported not having an acutely injured animal for greater than 36 months. Most respondents had a positive attitude towards OFES for animal welfare reasons and were aware of relevant regulations and guidelines. Barriers to OFES included a lack of availability of OFES, and dairy farmers indicated that it had a similar financial impact as euthanasia. A parallel study with veterinarians indicated a higher incidence of acutely injured cattle in Ireland; the current results may be due to the demographic or the sensitivity of the topic. Nationwide electronic data capture on the cause of mortality could support improvements in the management of acutely injured cattle and enable surveillance of the proportion of these cattle undergoing OFES, euthanasia, or CS.
