Exploring the Opinions of Irish Dairy Farmers Regarding Male Dairy Calves

Trends and factors associated with dairy calf early slaughter in Ireland, 2018-2022

Dairy systems require that each cow calves annually to have an efficient milk production cycle. In systems where milk production is maximized, the male offspring from dairy breed sires tend to have poor beef production traits and, therefore, can be of low economic value. Few studies have been published on the factors impacting early slaughtering of calves in peer-reviewed literature. Here we present an analysis of national data on calves slaughtered from 2018 to 2022 in Ireland. Data (Jan 2018-May 2022) on all cattle <6 months of age were collated at a national level and were described at calf-, herd-, and county-levels. These data were statistically analyzed at per-capita slaughter rates (calves/calf born) using negative binomial regression models with an offset. There were 125,260 calves slaughtered early (1.09% of total births) recorded in the dataset from 1,364 birth herds during the study period, of which 94.8% (118,761) were male. 51.7% were classified as Friesian-cross (FRX), 11.5% Friesian (FR) and 32.1% Jersey-cross (JEX). The median age at slaughter was 16 days (Mean: 18.9 days; IQR: 13-22). The median calves/herd slaughtered was 16 (mean: 91.8); median calves/herd/year slaughtered was 21 (mean: 42.0). There was substantial variation in counts of calves slaughtered across herds, years, and counties. Herd calf slaughter rates and per capita calf slaughter rates increased significantly in 2022, with the highest rates over the time series. Calf slaughter rates varied significantly with herd size, year, and major breed (Jersey; JE). Herds which were more recently established tended to have higher calf slaughter rates. Herds that repeatedly slaughtered calves over 2 or more years tended to be larger and slaughtered more calves/herd/year. The slaughtering of calves is not widespread across the dairy industry in Ireland. The distribution of calves slaughtered per herd demonstrate that a small number of herds contributed disproportionately to calf slaughter numbers. Such herds tended to be very large (herd size), more recently established (2016 onwards), and have higher proportions of JE/JEX breed cattle. The outcomes of the present study provide an evidential base for the development of targeted industry-lead interventions with the aim of ending the routine early slaughter of calves.

Canadian dairy farmer views about animal welfare

Concerns regarding the welfare of farm animals continue to grow. Traditionally, research efforts have largely focused on refining existing management practices to improve welfare. However, the incorporation of views from those directly involved in animal care is equally, if not more, important. This study investigated the perspectives of Canadian dairy farmers on animal welfare. We conducted 16 interviews with a total of 22 participants from four provinces across Canada. Recorded audio files and field notes were transcribed, anonymised, and coded using deductive and inductive thematic analysis. The interview data revealed two major themes: (1) animal dimension of animal welfare, including views related to biological functioning, naturalness and affective states; and (2) dairy farmer identity, including, the voice of the 'city', what it means to be a good 'cow-man', and the nature of human-animal relationships. Dairy farmers emphasised biological functioning, but they made numerous references to the emotional and natural living aspects of their animals' lives. Our work also provides evidence that farmers believed it was their duty to care for their animals beyond simply milking cows and making a profit. In terms of the larger debate, this study identified potential shared values with members of the public: opportunities for natural living and agency, attentiveness to individual animals, and the value of life over death. Finally, the emotional relationship that farmers developed with their animals highlights the values dairy farmers have for their animals beyond simply utilitarian function. Overall, these shared values could contribute to constructive dialogue.

Prevalence of respiratory disease in Irish preweaned dairy calves using hierarchical Bayesian latent class analysis

Introduction

Bovine respiratory disease (BRD) has a significant impact on the health and welfare of dairy calves. It can result in increased antimicrobial usage, decreased growth rate and reduced future productivity. There is no gold standard antemortem diagnostic test for BRD in calves and no estimates of the prevalence of respiratory disease in seasonal calving dairy herds.

Methods

To estimate BRD prevalence in seasonal calving dairy herds in Ireland, 40 dairy farms were recruited and each farm was visited once during one of two calving seasons (spring 2020 & spring 2021). At that visit the prevalence of BRD in 20 calves between 4 and 6 weeks of age was determined using thoracic ultrasound score (≥3) and the Wisconsin respiratory scoring system (≥5). Hierarchical Bayesian latent class analysis was used to estimate the calf-level true prevalence of BRD, and the within-herd prevalence distribution, accounting for the imperfect nature of both diagnostic tests.

Results

In total, 787 calves were examined, of which 58 (7.4%) had BRD as defined by a Wisconsin respiratory score ≥5 only, 37 (4.7%) had BRD as defined by a thoracic ultrasound score of ≥3 only and 14 (1.8%) calves had BRD based on both thoracic ultrasound and clinical scoring. The primary model assumed both tests were independent and used informed priors for test characteristics. Using this model the true prevalence of BRD was estimated as 4%, 95% Bayesian credible interval (BCI) (1%, 8%). This prevalence estimate is lower or similar to those found in other dairy production systems. Median within herd prevalence varied from 0 to 22%. The prevalence estimate was not sensitive to whether the model was constructed with the tests considered conditionally dependent or independent. When the case definition for thoracic ultrasound was changed to a score ≥2, the prevalence estimate increased to 15% (95% BCI: 6%, 27%).

Discussion

The prevalence of calf respiratory disease, however defined, was low, but highly variable, in these seasonal calving dairy herds.

Dairy producer perceptions toward male dairy calves in the Midwestern United States

Male dairy calves are often sold from the farm of birth within the first few days of life. Research describing the care of male calves is limited, with an emphasis on parsing differences between the care of male and female calves. The aims of this study were to describe dairy producers’ self-reported care practices for male relative to female calves, as well as their perceptions toward male calf care and welfare. Overall, 24 dairy producers in Ohio and Indiana participated in 1 in-person focus group (n = 10) or were individually interviewed (n = 14) using a semi-structured questionnaire with closed and open-ended questions about neonatal calf care and welfare. Discussions were audio recorded and transcribed verbatim. Data from closed-ended questions are described quantitatively, and thematic analysis was used to identify common themes discussed by producers for open-ended questions. A majority of producers described using different care protocols for male and female dairy calves (64%; 9/14 interview participants). Low input care practices were more commonly consistent between male and female calves, such as colostrum protocols (71%; 10/14 interview participants) and navel care (100%; 14/14 interview participants) than more costly treatments. Of the producers that provided disease prevention products to female calves (79%; 11/14 interview participants), only a few also administered them to male calves (27%; 3/11 interview participants). Three major themes were constructed from the open-ended questions, including factors affecting male dairy calf care, attitude toward male calf welfare, and opportunities to improve male dairy calf welfare. Producers described multiple factors that influenced male calf care on the dairy, such as time and money required to care for them. There was divergence in concern among producers about male calf welfare, with some producers expressing concern, particularly for calves slaughtered soon after birth; yet others described feelings of indifference about the topic. Potential ways to improve male calf welfare, including greater sale prices and the involvement in specialized marketing schemes, were suggested by some producers. These findings highlight potential concerns for male calf welfare and ways to improve future care on dairy farms.

What Do the Public Want to Know about Farming and Why? Findings from a Farmer-Initiated Public Consultation Exercise in Ireland

With advances in information communication technologies and sustainability-driven changes in consumer behavior, farmer–citizen communication is a communicative dyad that is receiving attention. Farmers and citizens view farming practices through very different lenses of prior knowledge, experiences, beliefs, and values, presenting unique communication challenges. Dialogue-based communication can help to build empathy and trust. Initiated by a committee of farmers, a public consultation exercise was carried out to facilitate citizens to deliberate over farming and farming practices in Ireland to better understand their views and perspectives, and identify information needs and knowledge gaps. Employing a participatory deliberative approach, 10 focus groups were carried out with members of the public (n = 65) carefully selected to represent diverse demographics in the general population. Findings are structured around two central themes. ‘Bridging the disconnect’ reflects the strong support found across the focus groups for farmer-led dialogic communication with citizens on farming practices. ‘Understanding knowledge gaps’ revealed the nature and underlying motivations of public information needs and knowledge gaps in specific areas: (1) the basics of farming; (2) the life of the farmer; (3) minding animals; (4) minding the environment; and (5) buying local and natural. Dialogue-based communication between farmers and citizens offers opportunities for supporting connected and sustainable food and farming systems through value-driven and responsive behavior change.

Current Consumer Perceptions of Animal Welfare across Different Farming Sectors on the Island of Ireland

Simple Summary

The well-being and welfare of animals on farms is a topic of interest to many people. On the island of Ireland, this issue has received increased attention because of political and governance changes, including Brexit and COVID-19. Policy-makers and industry are considering labelling schemes to inform the food consumer about welfare standards on farms. Focus groups and an online survey were carried out with members of the public on the island of Ireland to explore their awareness, perceptions, and attitudes toward farm animal welfare standards on farms in Ireland and Northern Ireland. Most consumers believed farm animal welfare standards were high, although different farming sectors were rated differently: beef and dairy farms were viewed more positively, and pig and poultry farms were viewed less positively. The living conditions of the animal, size and intensity of the farm, national standards and schemes, and visibility all influenced perceptions of welfare standards. The public also expressed a lack of knowledge and information on the topic. In developing new policies and labelling schemes, it is important to be apprised of the current awareness, attitudes, and perceptions that the public has regarding farm animal welfare standards, as identified in the current paper.

Abstract

There has been increased public interest and concerns in issues such as farm animal welfare (FAW) on the island of Ireland, stoked in part by political and governance changes, such as Brexit and COVID-19. Front-of-pack food labelling represents a primary information channel for many people. In advance of considering formalised food labelling schemes, specifically relating to FAW, it is important to ensure an up-to-date understanding of current consumer perceptions of FAW. With this aim, the current study utilised a mixed methodology. Nine focus group discussions (n = 41) and an online survey (n = 972) with food consumers in Ireland and Northern Ireland explored perceptions of FAW. Results suggest that overall perceptions of FAW are high, and consumers perceive FAW to have improved in the last decade. Quantitative (ANOVA) and qualitative results show variations in perception of FAW between sectors. Results from the focus group discussions identified factors underlying consumers’ perception of FAW: the living conditions of the animal, size and intensity of the farm, national standards and schemes, and visibility. Information insufficiencies and knowledge gaps were identified. The findings are discussed in relation to policy implications for the role of public engagement, front-of-pack welfare labelling, and quality assurance schemes.

Exploring the Opinions of Irish Beef Farmers Regarding Dairy Beef Integration

Background: There has been very little previous research in Ireland on the opinions of farmers regarding dairy beef integration. The need for increased dairy beef integration has assumed a greater importance in Ireland in recent years due to a rapid expansion in dairy production, and associated increase in numbers of male dairy calves born on Irish farms. The objective of this study was to explore beef farmers' views on a broad range of issues related to dairy beef integration, using a survey methodology. The survey was distributed to approximately 4,250 beef farmers via email and 1,203 participated in the study.

Results: The sample was composed almost entirely of beef farmers, although a very small proportion also had a dairy enterprise on their farm. Eighty percent of the farmers were concerned with the increase in the number of male dairy calves in recent years. Fifty seven percent of farmers responded that they were not willing to rear dairy bred calves for beef. Limousin, Aberdeen Angus and Hereford were the breeds farmers would be most willing to rear for beef. Good health, breed, and conformation were ranked as the main factors calf rearers consider when buying calves. Expectation of poor profit margin, expectation of poor-quality calves, and price volatility/market uncertainty were the top ranked factors dissuading farmers from rearing dairy calves for beef. The main themes arising from the qualitative question related to beef price/ability to make a profit, breed, and calf quality.

Conclusions: While it is concerning that the majority of respondents expressed an unwillingness to rear dairy bred calves for beef, approximately a quarter of beef farmers indicated a willingness to rear beef-sired dairy calves for beef. In the qualitative responses, farmers described how their concerns about calf quality and their ability to make a profit from dairy bred calves would make it difficult for them to rear these calves for beef. Future strategy will have to consider how these challenges can be overcome and the issues of who bears the risks and costs associated with greater integration will have to be carefully considered.
