Dairy marketing cooperatives provide marketwide services, such as lobbying for higher support prices and negotiating for premiums above marketing order prices, which benefit all dairy farmers in the market. The presence of free riders, people who benefit from these marketwide services without paying any of the costs of these services, can jeopardize the existence of the cooperative. Understanding why members were attracted to the cooperative and why independents (non-members) were attracted to the investor oriented firm (IOF) allows cooperatives to target specific membership groups. Depending on the cooperative's goals, management can then use this information to focus on either retaining current members or attracting new members or both. The purpose of this study is to produce practical recommendations for dairy marketing cooperatives for recruitment and retention of members. This study begins with a background on cooperatives and a conceptual framework based on group and game theory. The data are a result of a regional survey of dairy farmers. The data are then analyzed using t-tests for continuous responses and chi-square tests for categorical responses. This analysis results in a comparison of responses from cooperative members and independents. The independents stressed immediate benefits over long-run gains. Independents also appeared to have a risk/return trade-off. They received higher prices in exchange for fewer written contracts. Economic issues were important to both groups but significantly more important to independent producers. The two groups exhibited no difference on tradition and loyalty issues. Cooperative members emphasized prices and deductions, but they also highlighted assured markets and field services offered by their cooperatives. / Master of Science

MScAgric / ABSTRACT: Small dairy farms in South Africa are observed to have higher costs than larger farms, and whether those higher costs are due to technology or inefficiency has implications for policy. This research focused on finding the curve that best represents the relationship between average cost and level of output. That was done by relating average cost to actual output. However, it was found to be more appropriate to relate average cost to planned output on the basis that costs are more likely to reflect what the farmer expects output to be. As a result, a pragmatic two-step procedure was adopted. In the first step, the farmer’s planned output was determined by estimating a production function based on the farmer’s actual use of inputs, i.e., land, number of cows in the herd, labour, feed and veterinary costs. In the second step, the long-run average cost (LAC) curve was estimated where average cost is calculated as total cost divided by planned output and this is then related to the level of planned output. To identify the determinants of production cost thus the drivers of higher costs on small farms, the cost of milk production by farm size was decomposed into frontier and efficiency components with a stochastic cost curve and long run cost curve using data from dairy farms in KwaZulu-Natal (South Africa). Financial data of 37 farms for the period 1999 to 2007 were used in econometrics estimation of long run average cost curve (LAC) function for different level of production (as a proxy of planned output). Results show that average cost curves exhibiting variation in unit cost with output thus suggesting the existence of economies of size with larger farms being able to produce any given level of output at lower costs compared to their smaller counterparts. The study found that long-run average cost curve (LAC) for the sample of dairy farms is L-shaped rather than U-shaped.

Organic dairying is growing in popularity in New Zealand and the demand for knowledge is ever increasing. Many more farmers are considering organics as an alternative to their current conventional system. However, limited information is available on organic dairying in a New Zealand pastoral situation particularly in relation to its effect on fertility. The New Zealand dairy industry requires the dairy cow to become pregnant every year at the same time to maximise milk production and utilise the high pasture production in spring. A cow requires 40 to 60 days for uterine involution to occur and for resumption of oestrous cycles. It is critical that the cow becomes pregnant within the six to eight week mating period, however, this can be difficult for late calvers or those cows that had or still have a uterine infection, to undergo uterine involution and be successfully mated. These cows will often not become pregnant and as a consequence be culled for infertility. During the first few weeks postpartum, the bacterial composition of the uterus fluctuates as a result of spontaneous contamination, elimination and recontamination. Most cows are able to eliminate these bacteria, however, 10 to 17% of cows are unable to do this. In these cows, the bacteria persist, cause infection and inflammation, and delay uterine involution. The main objective of this present study was to investigate the effect of different management systems (Organic and Conventional) on productivity and reproduction, particularly the process of uterine involution and its relationship with reproductive outcomes. Uterine involution will be studied through the following measurements: cervical diameter as assessed by measurement per rectum, plasma concentrations of glucocorticoids and bacteriology of the uterus. Lactation characteristics: milk yield, cumulative milk yield, milksolids production and somatic cell count will also be investigated. From the results, it can be concluded that Organic cows have reduced milk yield (P=0.05) and milksolids production (P<0.01) through there were no major differences at peak lactation or in the rate of decline after. However, overall somatic cell count was not affected by management system though the Conventional cows had high somatic cell counts in early lactation (P=0.925). Cervical diameter was affected by the management system with the difference between Organic and Conventional cows almost significant (P=0.06). Cortisol concentrations were significantly higher in Organic cows (0.68 ± 0.08 ng/ml) when compared to Conventional cows (0.95 ± 0.06 ng/ml) (P=0.01). Cortisol concentrations decreased over time postpartum (P<0.01). Additionally Organic cows had a shorter interval from calving to AI (P=0.017). However, none of the other reproductive outcomes were affected by management system. Simple correlations established that reproductive outcomes and bacterial counts, reproductive outcomes and cortisol at Day seven, and cortisol and milk production characteristics, were not independent of each other. Aerobic bacterial counts on Day 28 and the interval from calving to AI were found to be significantly correlated (r= 0.615). Stepwise partial regression analysis, plus analysis of variance calculated on the relationships between uterine involution parameters and reproductive outcomes found multiple weak correlations. It found that cervical diameter, and aerobic and anaerobic bacterial counts on Day 28 were significantly correlated with the interval from calving to first AI (P=0.018). The differences in lactation characteristics are related to the lower pasture production on the organic farmlet reducing the maximal potential milk production and the possibly earlier calving dates of the Conventional cows. The differences in bacterial counts and almost significant difference in cervical diameter may be related to the lower cortisol levels and thus suggest that the Organic cows may be less stressed. As stress suppresses the immune system, it may be possible that the higher bacterial counts are indicitative of a less efficient or slightly weakened immune system which takes longer to eliminate bacteria in the uterus; however this is open to conjecture. The shorter interval from calving to AI suggests that Organic cows may be exhibiting oestrus behaviour earlier postpartum or the Conventional cows are having “silent heats” but this difference is possibly related to human factors. The correlation between parameters of uterine involution and interval from calving to AI, and the lower values for uterine involution parameters in Organic cows suggest the possibility of faster uterine involution and this may result in better fertility in the Organic cows. More research needs to be carried out to further investigate the effect of organic dairying on uterine involution and reproduction outcomes but organic dairying at the very least does not negatively impact on uterine involution and fertility.

PhDRDV / Institute for Rural Development / As has been the case in Eastern and Southern Africa, Zimbabwe continues to regard smallholder dairy farming as a viable strategy for reducing poverty and malnutrition, especially in rural areas. Although the country has since the early 1980s been promoting smallholder dairy development, available literature does not provide a clear picture of the extent to which the specific livelihoods of rural communities in terms of human, social, physical and financial capitals, have improved. Nor is there knowledge on its negative contribution to the farmers’ livelihoods. Thus, this study was undertaken to critically analyse the contribution of smallholder dairy farming towards the livelihoods of rural households using the Nharira dairy scheme as a focal area. The DfiD sustainable livelihood framework was used to build this understanding. Apart from characterizing the farmers, the contribution of smallholder dairy farming towards social, physical, human, natural and financial capitals was investigated. A sequentially integrated mixed methods approach was used. This was divided into two phases, which were quantitative and qualitative in nature. Results from the first phase were used to inform and design the second study. A census of the 21 active smallholder dairy farmers in Nharira, and management committee of the Nharira dairy processing plant was conducted. A household-focused questionnaire, key informant interviews, participatory mapping, record review, Global Positioning System (GPS) locating and focus group discussions were used to collect data. A tape recorder, GPS locator and camera were used as assistive devices during data collection. Thematic content analysis was used to analyse qualitative data and interpret participatory maps. Livelihood capital indices were derived per household and used to complement descriptive statistics as part of quantitative data analysis. A social capital index was computed for each household using collective action, empowerment, groups and networks, and trust and solidarity as its components. Resource stocks and access were the building blocks of the natural capital index. Income, savings and investments, and access to funding were used to derive the household financial capital index. Contribution of dairy farming to productive equipment (such as cattle herd size) and basic infrastructure (such as quality of housing) were used to calculate the physical capital index. The index for human capital was obtained taking into account education, workforce and employment, enabling environment, and health and wellness. Equal weights were applied to the components when deriving the household livelihood indices because each one of them was considered to be substantially important for sustainable livelihoods. The quantitative data were stored and analysed using the International Business Machines (IBM) Statistical iii Package for Social Sciences (SPSS) version 24. Pearson correlation coefficients, means and standard deviations were calculated. Most of the farmers (65 %) were female. Approximately, 95 % of the women farmers were literate. Only 1 % of the farmers were youth (< 35 years old), a situation that threatened the sustainability of smallholder dairy farming. A daily smallholder dairy farming routine was derived using the focus group and participatory mapping results. This showcased the various daily activities and linked them with the household members actively involved. Smallholder dairy farming was found to be labour intensive. This might deter the farmers from diversifying into other livelihood strategies. Smallholder dairy farming was observed to have strengthened financial, human, natural, physical and social capitals in the local households. However, the respective indices of 0.59 and 0.52 for social and natural capitals, suggested that smallholder dairy farming impacted on these more than any other. Even though social capital was strong, further reinforcement through improved smallholder dairy farming activities was still vital because of its power of enhancing access to other forms of livelihood capitals. Human and physical capitals had the least index scores of 0.48 and 0.47, respectively. On average, the overall household livelihood capital index as a result of smallholder dairy farming was 0.51. One of the study respondents supported the positive contribution in the following way, ‘’Zvakanakira dairy hatingazipedzi. Tinotoda zuva rese” (There are many positive things that we attribute to our involvement in smallholder dairy farming. Narrating these demands considerable time). It was concluded that smallholder dairy farming significantly strengthened livelihood capitals of households involved in it. The results of the current study suggest that smallholder dairy farming is a viable option for improving household livelihood capitals. Thus, establishment of dairy farming schemes in rural areas should be promoted. However, the participation of youth in smallholder dairy farming as enterprise owners deserves attention because it threatens sustainability of the sector. An integrated multiple angle view encompassing technical, social, institutional, economic and organizational ideas of the impact of dairy farming as a livelihood strategy on household capital portfolio was provided. Moreover, application of the sustainable development framework to understanding the smallholder dairy farming context at household level was a novel way of understanding the local realities. Lastly, a set of variables that can be utilised to measure livelihood capitals of households involved in smallholder dairy farming-related activities was distilled.

This study presents two separate competitiveness analyses to assess changes in, and factors influencing, the long-term competitiveness of a panel of commercial milk producers in East Griqualand (EG), South Africa. The Unit Cost Ratio (UCR) method was used to measure competitiveness of EG milk producers. It is defined as the ratio of dairy enterprise accounting costs plus an opportunity cost of management at 5% of milk revenue, to total dairy enterprise revenue. The initial UCR analysis was used to partly investigate the impact of dairy market deregulation on the relative competitiveness of EG milk producers over the period 1983 to 2006. The results of this UCR analysis found that the sample of EG milk producers were not competitive based on the net local price, PL, received for milk but were competitive when dairy cattle trading income was included. This suggests that dairy cattle trading income played an important role in enhancing the competitiveness of EG dairy enterprises in the study period. Further UCR analysis revealed that differences in the inherent ability of members of the EG group to manage market deregulation impacted on the relative competitiveness of EG milk producers. The top onethird of the sample of EG milk producers remained relatively competitive from 1983 to 2006 due to higher real milk prices and lower real unit costs than producers in the bottom one-third category. Differences in relative competitiveness between the top and bottom one-third categories of producers were statistically significant. Based on the findings of the UCR analysis, a Ridge regression analysis was then used to investigate other factors influencing the long-term competitiveness of selected milk producers from EG using unbalanced panel data for the period 1990 – 2006. Results of the regression analysis showed that dairy herd size, the level of farm debt, annual production per cow, technology and policy changes over time, and the ratio of trading income to total milk income influence the long-term competitiveness of these milk producers. To enhance their competitiveness in a deregulated dairy market, relatively small and profitable EG milk producers should consider increasing herd sizes as the importance of herd size in explaining competitiveness suggests that size economies exist. All EG milk producers should consider utilising more pasture and other forages to lower feed costs and select dairy cattle of superior genetic merit to improve milk yields. / Thesis (M.Sc.)-University of KwaZulu-Natal, Pietermaritzburg, 2009.

This project investigated the business, environmental and social sustainability of dairy farms that include dairy support land. Seventeen farmers were interviewed using Yin’s case study method (Yin, 2003). The interviewees were selected from a list provided during a series of focus groups done with rural professionals prior to continuing with the main body of the research. Those interviewed saw that the primary role of dairy support land is to protect the dairy farm from external factors. Dairy farms are vulnerable to externalities due to high fixed costs and the relationship between cow condition and milk production. The ability of dairy support land to manage externalities relates to quantity of feed grown, therefore feed grown is perceived as the most appropriate measure of performance. For dairy support land to be sustainable, it must be well resourced. On a fully resourced DSL unit, there will be time to plan and carry out essential tasks and environmentally important developments such as riparian fences and stockwater systems are likely to be in place. If the dairy support land unit is not fully resourced it will become a liability to the overall system as the supply of feed becomes unreliable, cows calve in poor condition and dairy farm staff and management are overextended. Poorly resourced dairy support land is also unlikely to have environmentally friendly developments in place. The case studies also demonstrated that the fundamentals of sustainability and practice remain constant across a variety of soil and climatic conditions in Canterbury and Southland.
