Beyond biofuels: jatropha’s multiple uses for farmers in East Africa

The jatropha plant produces seeds containing 25–40% oil by weight. This oil can be made into biodiesel. During the recent global fuel crisis, the price of crude oil peaked at over USD 130 per barrel. Jatropha attracted huge interest – it was touted as a wonder crop that could generate biodiesel oil on “marginal lands” in semi-arid areas. Its promise appeared especially great in East Africa. Today, however, jatropha’s value in East Africa appears to lie primarily in its multipurpose use by small-scale farmers, not in large-scale biofuel production.

[Castration of calves: a survey among Swiss suckler beef farmers]

In fall 2004, a survey of a representative sample of 1185 Swiss suckler beef farmers was carried out by questionnaire (return rate 51.9%). 32.7% of the respondents castrated their calves without the help of a veterinarian, 37.8% mandated a veterinarian to carry out the castrations and 29.4% did not castrate their bull calves at all. On average, 8 calves were castrated per farm and year at an average age of 7 days when the castration was carried out by a farmer or 34 days when the castration was carried out by a veterinarian. Almost all farmers castrated their calves with the rubber ring, and a majority considered no other method as feasible. 73.9% of the veterinarians used the Burdizzo technique, 14.9% applied rubber rings, and 11.2% performed a surgical procedure. 22.6% of the farmers and 85.4% of the veterinarians used sedation; local anaesthesia was performed in 32.1% of the castrations carried out by farmers and in 84.5% of the castrations carried out by veterinarians. 65.7% of the farmers were concerned by the change of the Swiss Animal Protection Ordinance (2001), when pain relief became mandatory. 47.6% of these farmers changed their castration routine: 53.1% now mandated a veterinarian, 33.0% used sedation or local anaesthesia and 8.9% abandoned castration of their calves. 59.8% of the farmers intended to participate in a future course for laymen, to study and train the technique of local anaesthesia for castration. Castration of their calves is for many suckler beef farmers an inevitable husbandry procedure. The political goal, that all calves shall be castrated with local anaesthesia can only be reached when livestock owners are informed about the distress caused by the castration and convinced of the benefit of the local anaesthesia.Veterinarians are important information carriers in this process. The implementation also produces work, be it the more complex castration procedure or the education of the farmers who want to carry out the local anaesthesia themselves.

The use of homeopathy in obstetrics in Switzerland

Objective In 1999, a first study conducted in the German speaking part of Switzerland revealed that homeopathy was used in 73% of the obstetrics. The aim of this follow-up study was to detect possible changes in the use of homeopathy since the first investigation, as well as to expand the survey to all regions of Switzerland in order to explore possible regional differences. Furthermore, the perceived positive and negative effects of homeopathy were of interest. Methods All maternity clinics (n = 119) and birthing centers (n = 25) in Switzerland were invited to participate in this online-survey (total N = 144). Results The data collection is still ongoing. Preliminary analyses show that of the 144 obstetrics contacted, 16 had shut down. 106 (82%) had returned the complete or partial questionnaire, whereof 86 (81%) were completed by maternity clinics and 20 (19%) by birthing centers. 70 (66%) questionnaires were returned from the German, 31 (29%) from the French and 5 (5%) from the Italian part of Switzerland. A total of 77 (73%) obstetrics indicated to apply homeopathy: 61 maternity clinics (71% of the responding ones) and 16 birth centers (80% of the responding ones). Clear regional differences in the use of homeopathy emerged: While 65 of the homeopathy-applying obstetrics were located in the German part of Switzerland (84% of the responding ones), only 11 (35% of the responding ones) and 1 (20% of the responding ones) were situated in the French and Italian regions respectively. More detailed results will be presented at the conference. Conclusion Preliminary results show that homeopathy is widely used in the obstetrics of Switzerland. Cultural differences appeared: Homeopathy is widely used in the German speaking part of Switzerland, while it is modestly employed in the French and Italian regions.

Effect of calf purchase and other herd-level risk factors on mortality, unwanted early slaughter, and use of antimicrobial group treatments in Swiss veal calf operations.

The objective of this survey was to determine herd level risk factors for mortality, unwanted early slaughter, and metaphylactic application of antimicrobial group therapy in Swiss veal calves in 2013. A questionnaire regarding farm structure, farm management, mortality and antimicrobial use was sent to all farmers registered in a Swiss label program setting requirements for improved animal welfare and sustainability. Risk factors were determined by multivariable logistic regression. A total of 619 veal producers returned a useable questionnaire (response rate=28.5%), of which 40.9% only fattened their own calves (group O), 56.9% their own calves and additional purchased calves (group O&P), and 2.3% only purchased calves for fattening (group P). A total number of 19,077 calves entered the fattening units in 2013, of which 21.7%, 66.7%, and 11.6% belonged to groups O, O&P, and P, respectively. Mortality was 0% in 322 herds (52.0%), between 0% and 3% in 47 herds (7.6%), and ≥3% in 250 herds (40.4%). Significant risk factors for mortality were purchasing calves, herd size, higher incidence of BRD, and access to an outside pen. Metaphylaxis was used on 13.4% of the farms (7.9% only upon arrival, 4.4% only later in the fattening period, 1.1% upon arrival and later), in 3.2% of the herds of group O, 17.9% of those in group O&P, and 92.9% of those of group P. Application of metaphylaxis upon arrival was positively associated with purchase (OR=8.9) and herd size (OR=1.2 per 10 calves). Metaphylaxis later in the production cycle was positively associated with group size (OR=2.9) and risk of respiratory disease (OR=1.2 per 10% higher risk) and negatively with the use of individual antimicrobial treatment (OR=0.3). In many countries, purchase and a large herd size are inherently connected to veal production. The Swiss situation with large commercial but also smaller herds with little or no purchase of calves made it possible to investigate the effect of these factors on mortality and antimicrobial drug use. The results of this study show that a system where small farms raise the calves from their own herds has a substantial potential to improve animal health and reduce antimicrobial drug use.

Consumption and food production in crisis time: Swiss consumption co-operations as farmers at the End of World War I

During the last two years of World War I food supply in Switzerland declined and caused shortcomings in consume, leading to social distress and conflict. Mainly two important factors caused these problems: First, Switzerland was highly dependent on food imports and during the war traditional supply lines faded. Second, weather extremes in the years 1916–1917 caused crop failure all over Europe and North America, which intensified the decline of food trade between the nations. In 1918 a conflict between classic urban consumers, such as workers, and famers erupted due to the food shortcomings and led to a lasting discord between urban and agrarian regions in Switzerland. But there was not only disharmony and conflict between the urban and agrarian regions. As a matter of fact several agents (urban and agrarian) interested in presenting adequate coping strategies to overcome the food shortages developed ideas of alternative ways of food production and supply since 1917. The aim of the paper is to outline these strategies that were undertaken to create a new era of food production that was not solely dependent on the agrarian sector or the import-trade. Actual growing of vegetables in estate areas is an important, but just one, factor of establishing a new system of food production, distribution and consume. The market-leading grocery stores in Switzerland nowadays (Coop and Migros) started their business during that time as co-operatives establishing new forms of distribution and food-production. So the interest of the paper is not only in actual «urban farming», but it wants to share some light on how swiss urban and agrarian spheres overlapped their functions in order to create a modern system of agro food-chains at the beginning of the interwar period.
