Relationships between farmer psychological profiles and farm business performance amongst smallholder beef and poultry farmers in South Africa

Beef cattle and poultry are critically important livestock for improving household food security and alleviating poverty amongst smallholder farmers in South Africa. In this paper, our goal is to examine the relationships between farmer psychological profiles and farm business performance of commercially oriented beef cattle and poultry smallholder farmers in South Africa. We employ a multipronged interdisciplinary approach to test the theory of planned behaviour and its relationship to farm business performance. First, a behavioural science-informed survey instrument was employed to collect data from randomly selected farmer participants in two major beef and poultry projects undertaken by the authors. Second, a latent profile analysis was used to identify the psychological profiles of those farmers. Third, traditional and estimated indicators of farm business performance were obtained using descriptive and econometric-based approaches, including logistic regression and stochastic frontier analyses. The estimated farm business performance indicators were correlated with the psychological profiles of farmers. Results from the latent profile analysis showed three distinct profiles of beef and poultry farmers clearly differentiated by their ability to control and succeed in their farm business enterprises; criteria included attitude, openness to ideas, personality, perceived capabilities, self-efficacy, time orientation, and farm- and personal-related concerns. Profile 1 (‘Fatalists’) scored themselves negatively on their ability to control and succeed in their business enterprises. The majority of farmers were generally neutral about their ability to control and succeed in their businesses (Profile 2, ‘Traditionalists’), while a relatively small group of farmers were confident of their ability to succeed (Profile 3, ‘Entrepreneurs’). We found evidence of significant differences in farm business performance amongst the different profiles of farmers. As far as we can determine, this is the only study to have assessed farm business performance based on a differentiation of farmers’ psychological profiles. Our results provide a framework to further investigate whether particular types of on-farm interventions and training methods can be customised for different segments of farmers based on their preferred learning styles

Multiple country and breed genomic prediction of tick resistance in beef cattle

Ticks cause substantial production losses for beef and dairy cattle. Cattle resistance to ticks is one of the most important factors affecting tick control, but largely neglected due to the challenge of phenotyping. In this study, we evaluate the pooling of tick resistance phenotyped reference populations from multi-country beef cattle breeds to assess the possibility of improving host resistance through multi-trait genomic selection. Data consisted of tick counts or scores assessing the number of female ticks at least 4.5 mm length and derived from seven populations, with breed, country, number of records and genotyped/phenotyped animals being respectively: Angus (AN), Brazil, 2,263, 921/1,156, Hereford (HH), Brazil, 6,615, 1,910/2,802, Brangus (BN), Brazil, 2,441, 851/851, Braford (BO), Brazil, 9,523, 3,062/4,095, Tropical Composite (TC), Australia, 229, 229/229, Brahman (BR), Australia, 675, 675/675, and Nguni (NG), South Africa, 490, 490/490. All populations were genotyped using medium density Illumina SNP BeadChips and imputed to a common high-density panel of 332,468 markers. The mean linkage disequilibrium (LD) between adjacent SNPs varied from 0.24 to 0.37 across populations and so was sufficient to allow genomic breeding values (GEBV) prediction. Correlations of LD phase between breeds were higher between composites and their founder breeds (0.81 to 0.95) and lower between NG and the other breeds (0.27 and 0.35). There was wide range of estimated heritability (0.05 and 0.42) and genetic correlation (-0.01 and 0.87) for tick resistance across the studied populations, with the largest genetic correlation observed between BN and BO. Predictive ability was improved under the old-young validation for three of the seven populations using a multi-trait approach compared to a single trait within-population prediction, while whole and partial data GEBV correlations increased in all cases, with relative improvements ranging from 3% for BO to 64% for TC. Moreover, the multi-trait analysis was useful to correct typical over-dispersion of the GEBV. Results from this study indicate that a joint genomic evaluation of AN, HH, BN, BO and BR can be readily implemented to improve tick resistance of these populations using selection on GEBV. For NG and TC additional phenotyping will be required to obtain accurate GEBV

Advancing a holistic systems approach for sustainable cattle development programmes in South Africa: insights from sustainability assessments

Efforts to exploit the central roles of cattle to drive agriculture and rural development in low-income countries recorded limited success owing to their narrow focus on modernizing and commercializing low-input cattle farming. Most programs failed to take cognizance of the heterogeneous range of complex relationships between the environmental, economic, social and institutional challenges that limit low-input cattle farming. The current qualitative literature review evaluates the environmental, economic and social sustainability delivery impacts of the leading cattle development programs in the low-input farming sector in South Africa using a holistic systems approach. A mixed method procedure involving stratified sampling was used to allocate local and international-based programs while, purposive sampling was used to select programs with a wider scale of operation. The review then draws on the crosscutting key constraints emerging from the case studies to provide a better grounding for subsequent sustainability sensitive recommendations. Local-based cattle development programs advanced more market-led interventions while, their international-based counterparts had more interventions including, soil and rangeland improvement. The narrow focus by both local and international developmental programs is inadequate to address a wide array of environmental, economic, social, technical and institutional challenges faced by low-input cattle producers in South Africa.The Department of Science and Technology-National Research Foundation (DST-NRF) Centre of Excellence (CoE) in Food Security [140102].https://www.tandfonline.com/loi/wjsa212021-01-23hj2020Gordon Institute of Business Science (GIBS

Towards a new phenotype for tick resistance in beef and dairy cattle:a review

About 80% of the world's cattle are affected by ticks and tick-borne diseases, both of which cause significant production losses. Cattle host resistance to ticks is the most important factor affecting the economics of tick control, but it is largely neglected in tick-control programs due to technical difficulties and costs associated with identifying individual-animal variation in resistance. The present paper reviews the scientific literature to identify factors affecting resistance of cattle to ticks and the biological mechanisms of host tick resistance, to develop alternative phenotype(s) for tick resistance. If new cost-effective phenotype(s) can be developed and validated, then tick resistance of cattle could be genetically improved using genomic selection, and incorporated into breeding objectives to simultaneously improve cattle productive attributes and tick resistance. The phenotype(s) could also be used to improve tick control by using cattle management. On the basis of the present review, it is recommended that three possible phenotypes (haemolytic analysis measures of skin hypersensitivity reactions simplified artificial tick infestations) be further developed to determine their practical feasibility for consistently, cost-effectively and reliably measuring cattle tick resistance in thousands of individual animals in commercial and smallholder farmer herds in tropical and subtropical areas globally. During evaluation of these potential new phenotypes, additional measurements should be included to determine the possibility of developing a volatile-based resistance phenotype, to simultaneously improve cattle resistance to both ticks and biting flies. Because the current measurements of volatile chemistry do not satisfy the requirements of a simple, cost-effective phenotype for use in commercial cattle herds, consideration should also be given to inclusion of potentially simpler measures to enable indirect genetic selection for volatile-based resistance to ticks

Effectiveness of a national quality improvement programme to improve survival after emergency abdominal surgery (EPOCH): a stepped-wedge cluster-randomised trial

Background: Emergency abdominal surgery is associated with poor patient outcomes. We studied the effectiveness of a national quality improvement (QI) programme to implement a care pathway to improve survival for these patients. Methods: We did a stepped-wedge cluster-randomised trial of patients aged 40 years or older undergoing emergency open major abdominal surgery. Eligible UK National Health Service (NHS) hospitals (those that had an emergency general surgical service, a substantial volume of emergency abdominal surgery cases, and contributed data to the National Emergency Laparotomy Audit) were organised into 15 geographical clusters and commenced the QI programme in a random order, based on a computer-generated random sequence, over an 85-week period with one geographical cluster commencing the intervention every 5 weeks from the second to the 16th time period. Patients were masked to the study group, but it was not possible to mask hospital staff or investigators. The primary outcome measure was mortality within 90 days of surgery. Analyses were done on an intention-to-treat basis. This study is registered with the ISRCTN registry, number ISRCTN80682973. Findings: Treatment took place between March 3, 2014, and Oct 19, 2015. 22 754 patients were assessed for elegibility. Of 15 873 eligible patients from 93 NHS hospitals, primary outcome data were analysed for 8482 patients in the usual care group and 7374 in the QI group. Eight patients in the usual care group and nine patients in the QI group were not included in the analysis because of missing primary outcome data. The primary outcome of 90-day mortality occurred in 1210 (16%) patients in the QI group compared with 1393 (16%) patients in the usual care group (HR 1·11, 0·96–1·28). Interpretation: No survival benefit was observed from this QI programme to implement a care pathway for patients undergoing emergency abdominal surgery. Future QI programmes should ensure that teams have both the time and resources needed to improve patient care.

Northern Australian beef production

Cattle were first introduced to Australia with European settlement in 1788. Growth in the Australian beef herd was initially slow, but expanded in the late 19th century with the discovery of gold and the advent of refrigerated transport. By 1900, the Australian beef herd was estimated at 8.6 million head (ABS 2005) and extended to most regions of Australia, including very large pastoral holdings in central and northern Australia. The subsequent impact of two world wars and the Depression saw numbers remain comparatively stable for the next 50 years. In 1950, the Australian beef cattle herd was 9.7 million head (ABS 2005). During the first half of the 20th century, beef production in northern Australia was limited by a lack of effective inland transport systems, a strong (alternative) wool industry in some areas of northern Australia and the poor adaptation of 'Bos taurus' breeds of cattle to the stressors of the tropical environments (McDonald 1988). This changed dramatically over the 1950s to 1970s with the emergence of export markets in the UK and the development of major export markets to the USA and Japan when the trade to Great Britain abruptly ended with its entrance to the European Union. After the beef slump of the mid 1970s and the successful eradication of brucellosis and tuberculosis, there has been an extraordinary expansion of Brahman and Brahman-derived cattle in northern Australia since the 1980s (Bindon and Jones 2001)

Genetic aspects of cattle adaptation in the tropics.

Improving the quality of life of many people living in tropical regions throughout the world is a very high global priority. For many of those people, this requires significant improvements to the productivity of their cattle herds, which comprise a major part of their household income (Payne and Hodges, 1997). Morgan and Tallard (2007) indicate that globally, there are ~1.5 billion head of cattle, with more than 65% located in the tropics and subtropics. Cattle make a major contribution to milk, meat and hide supply and additionally, in some regions, they are a major source of draught power and manure for use as fuel and maintaining soil fertility

The value of research: using the 'Impact Tool' to evaluate realised and anticipated benefits of the Cooperative Research Centre for Beef Genetic Technologies

The Cooperative Research Centre (CRC) for Beef Genetic Technologies operated for its third successive 7-year term from July 2005 to June 2012. It developed new genetic and genomic technologies and non-genetic 'products' (practices, processes, tools and technologies) to improve profitability, productivity, animal welfare and responsible resource use of Australian beef businesses. In this paper we assess how well the third-term Beef CRC met its objectives, at the end of its funding period, using the 'Impact Tool' software package developed by the CRC Program of the Commonwealth Government. The 'Impact Tool' generates two commonly used measures of return on investment: the net present value (NPV) and the benefit : cost ratio (BCR). The NPV, the sum of discounted benefits minus the sum of discounted costs, was $233.2 m, when evaluated over the period 2005/06-2020/21. The BCR, the sum of discounted benefits divided by the sum of discounted costs, was 2.94, over the same period. Thus on both measures, investing in the Beef CRC is expected to have been profitable. We conclude by noting that the value of the 'Impact Tool' is not only for ex-ante and ex-post evaluation of the impacts of particular technologies, but it also provides a very effective tool for RD&E project planning
