The present work was undertaken to determine the dynamics of changes taken place in farm animal production system of Bangladesh transmuting gradually on a cusp of increasing feed and food competition and gaining competitive advantages in domestic production of milk, meat and eggs. The data available from livestock population of the Agricultural Census of 1960 and of 1977, Agricultural and Livestock Census of 1983-84, the census of agriculture 2008 and the livestock and poultry survey of 2009 were used to figure out quantitative changes and extrapolate inherent causes of them. During the period of 1960 to 2009 human population increased at a faster pace (55.2 million to 144.0 million) than livestock population (10.5 to 17.0 livestock units). The later may be explained by a reduction of per capita availability of bovine animals (0.38 in 1960 to 0.18 in 2009) while the same for small ruminants remained similar (0.12 to 0.12, respectively), and that of poultry increased from 0.65 to 1.07, respectively. However, over the decade dairy farming, cattle fattening and commercial poultry supported increased production of livestock products. The ratio of total cows to adult male cattle of 0.56 in 1960 increased to 0.88 in 1977 reflecting farmers` interest on dairying, and the trend was being continued till 2009. Farm animal population at medium and large farms decreased over the period significantly (P<0.01) but, it increased at Non-farm and small farm levels and the difference was significant (P<0.01) in different areas of the country. Compared to the livestock unit of 1984 the extent of its increase at Non-farm and small farm level was 228.0% and 82.0%, respectively, and the extent of decrease at medium and large farm level was 24.9% and 49.9%, respectively. Fragmentation of land reduced medium and large farm numbers resulting in an increase of non-farm and small farm households over the time, and keeping farm animals by the latter gradually increased the share of livestock by land poor peoples. The trends being continued over the decades may impact livestock productions further. This requires data generation through regular agricultural census emphasizing socioeconomic and geographical changes in livestock productions more for identification and quantification of factors dictate ongoing transformation process and driving strategic policy implications to achieve sustainable livestock production integrating measures for climate changes.Bang.

Postmortem Examinations

Postmortem examinations can be a useful diagnostic tool in farm animal medicine; however, they are often avoided in general practice because of a lack of appropriate facilities and expertise/familiarity with techniques. This article describes the setting up of a basic facility to allow general practitioners to perform postmortem examinations of calves, small ruminants and other small animals, e.g. poultry.

Naive Approach

The concept of welfare applied to farm animals has undergone a remarkable evolution. The growing awareness of citizens pushes farmers to guarantee the highest possible level of welfare to their animals. New perspectives could be opened for animal welfare reasoning around the concept of domestic, especially farm, animals as partial human artifacts. Therefore, it is important to understand how much a particular behavior of a farm animal is far from the natural one of its ancestors. This paper is a contribution to better understand the role of genetics of the farm animals on their behavior. This means that the naïve approach to animal welfare regarding returning animals to their natural state should be challenged and that welfare assessment should be considered.

Course Of Action

It costs money to improve the welfare of farm animals. For people with animals under their care, there are many factors to consider regarding changes in practice to improve welfare, and the optimal course of action is not always obvious. Decision support systems for animal welfare, such as economic cost–benefit analyses, are lacking. This review attempts to provide clarity around the costs and benefits of improving farm animal welfare, thereby enabling the people with animals under their care to make informed decisions. Many of the costs are obvious. For example, training of stockpeople, reconfiguration of pens, and administration of pain relief can improve welfare, and all incur costs. Other costs are less obvious. For instance, there may be substantial risks to market protection, consumer acceptance, and social licence to farm associated with not ensuring good animal welfare. The benefits of improving farm animal welfare are also difficult to evaluate from a purely economic perspective. Although it is widely recognised that animals with poor welfare are unlikely to produce at optimal levels, there may be benefits of improving animal welfare that extend beyond production gains. These include benefits to the animal, positive effects on the workforce, competitive advantage for businesses, mitigation of risk, and positive social consequences. We summarise these considerations into a decision tool that can assist people with farm animals under their care, and we highlight the need for further empirical evidence to improve decision-making in animal welfare.

This study aims at exploiting research outcomes concerning tillage practices in order to make solutions available to farmers to mitigate negative environmental impact to soils. Two alternative practices have been analysed against conventional full tillage based on data provided by a long-term experiment conducted at the Institute of Soil Science and Plant Cultivation (IUNG) farm in Grabów, Central Poland. Reduced Tillage and Direct Sowing are evaluated against Full Tillage on the basis of socio-economic and environmental criteria. Multi-criteria decision analysis undertaken using the PROMETHEE method provided evidence that the ‘optimal’ maize cultivation system depends on the decision maker’s viewpoint and preferences. In fact, criteria selected and related weights elicited from representative farmers, as well as from an expert agronomist, reveal different viewpoints. Direct sowing was the most preferable for the large farm and expert perspective, whereas in case of small farm reduced tillage ranked first. Prospect theory developed by behavioural economists was incorporated to take into account decision biases. As a matter of fact, based on Prospect Theory-PROMETHEE from the small farm and the expert perspective, the conventional system was now ranked first, while for the large farm, the most preferable practice was still direct sowing.

The authors of the article presents the results of the development of a polyvalent toxoid from C.perfringens strains against anaerobic enterotoxaemia of young cattle and small ruminants and an assessment of its effectiveness. It is presented the data on the selection of the recipe composition of the nutrient medium, the cultivation of industrial strains, the process of drug preparation, the selection of the optimal ratio of components and the method of controlling the effectiveness. Sequential cultivation of industrial strains of C.perfringens was carried out by cultivating them in flasks, bottles and bioreactors in the nutrient medium developed by the authors, consisting of: 12.0 g/l - liver extract; 25.0 g/l - casein-peptone; 3.2g/l –K2HPO4; 1.8 g/l – KH2PO4; 0.5 g/l – MgSO4. The development of the drug included the selection of optimal and balanced ratios of C. perfringens type A toxoids - 15 IU/ml, C.perfringens type B - 20 IU/ml, C.perfringens type C - 30 IU/ml, C. perfringens type D - 30 IU/ml, which ensured 100% protection of the immunized animals. Studies on laboratory and farm animals revealed the harmlessness, areactogenicity of the drug, which stimulated the development of immunity and resistance to the toxic effects of all strains of C.perfringens.

The fate of transgenic DNA (tDNA) and protein from feed derived from Genetically Modified organisms (GMOs) in animals has been a major issue since their commercialization in 1996. Several studies have investigated the risks of horizontal gene transfer (HGT) of tDNA and protein to bacteria or animal cells/tissues, but some of the reported data are controversial. Previous reports showed that tDNA fragments or proteins derived from GM plants could not be detected in tissues, fluids, or edible products from livestock. Other researchers have shown that there is a possibility of small fragments entering animal tissues, fluids and organs. This motivated us to update our knowledge about these concerns. Therefore, this review aimed to evaluate the probable transfer and accumulation of tDNA/proteins from transgenic feeds in animal samples (ruminant and non-ruminant) by evaluating the available experimental studies published scientifically. This study found that the tDNA/protein is not completely degraded during feed processing and digestion in Gastro-Intestinal Tract (GIT). In large ruminants (cattle), tDNA fragments/proteins were detected in GIT digesta, rumen fluid, and faeces. In small ruminants (goats), traces of tDNA/proteins were detected in GIT digesta, blood, milk, liver, kidney, heart and muscle. In pigs, they were detected in blood, spleen, liver, kidney, and GIT digesta. In poultry, traces were detected in blood, liver and GIT digesta but not in meat and eggs. Notwithstanding some studies that have shown transfer of tDNA/protein fragments in animal samples, we cannot rely on these few studies to give general evidence for transfer into tissues/fluids and organs of farm animals. However, this study clearly shows that transfer is possible. Therefore, intensive and authentic research should be conducted on GM plants before they are approved for commercial use, investigating issues such as the fate of tDNA or proteins and the effects of feeding GM feed to livestock.

This study was conducted to identify the technical and economical performance of the existing models of maize sheller in the country and suggest the best maize sheller models for the farmers during 3 September 2006 to 30 March 2007 in the area of Bogra, Rangpur, Dinajpur, Rajshahi and Jessore. Detail field tests were conducted on seven selected maize sheller models of three categories to assess the comparative performance. Three basic designs of maize sheller models were identified through field survey and secondary information. The models were Spike-pinion (SP) type, Spiral rasp-bar cylinder (SBC) type and Parallel rasp-bar cylinder (PBC) type. The technical performances of the selected maize sheller models were evaluated on the basis of throughput capacity, shelling capacity, cylinder loss, separating loss, broken kernel and shelling efficiency. The shelling capacity and efficiency of Binimoy and Sarker spike-pinion (SP) type models were found about 0.45 ton/hr and 93%, respectively. Similarly, the shelling capacities and efficiencies of Farida, Rahman and Uttaran spiral rasp-bar cylinder (SBC) models were ranged between 2.8 to 4.0 ton/hr and 93 to 97%, respectively. Farida parallel rasp-bar (PBC) type maize sheller had shown incredible shelling efficiency of about 99% with almost negligible cylinder (0.25%) and separating (0.25%) losses along with lowest broken kernel (2.5%) percentage. However, the shelling capacity was found comparatively low about 1.9 ton/hr. The shelling costs, benefit-cost ratios and net margins of spiral rasp-bar cylinder models vary between Tk. 91-97/ton, 1.28-1.37 and Tk78-134/hr, respectively. Among the models Farida (SBC) appeared as the most economic one having lowest shelling cost of Tk. 91/ton with the highest benefit-cost ratio of 1.37 and net margin of Tk. 134/hr (determined at a custom-hire rate of Tk. 7 per 40 kg of shelled kernel). Comparative economic uses of the selected maize shellers suggest that the use of hand sheller is beneficial up to an annual use of 13 ton. Whereas, Binimoy (SP) and Sarker (SP) models are economic for annual use between 13 and 30 ton, and Farida (SBC), Rahman (SBC) and Uttaran (SBC) models are economic for shelling over 30 ton per annum. Economic analysis suggest that hand sheller could be beneficial for very small farm holdings, Binimoy (SP) and Sarker (SP) models for small farm holdings and Farida (SBC), Rahman (SBC) and Uttaran (SBC) models for medium to large farm holdings and custom-hire service.DOI: http://dx.doi.org/10.3329/pa.v20i1-2.16873 Progress.

AbstractTo assess farm animal welfare we need to understand how animals make choices and how these choices relate to preference strength. Studies of environmental choice can be categorized by the method used to investigate them, or by the underlying basis on which the animal is choosing. Choices made between resources that vary along a single dimension should meet certain criteria e.g. those of transitivity. Choices made between resources that vary along more than one dimension may or may not meet these criteria, depending how the animal evaluates each option. Understanding how farm animals choose will allow the results of individual experiments to be applied in a wider context. It is also important to know how preferences are formed during development. Evidence suggests that preferences for nests and pecking substrates in hens may be influenced by prefunctional experience. Experimental data from studies of environmental choice may enable us either to provide important resources in commercial systems, or to provide facilities for animals to continue to make their own decisions.

Farm Animal Welfare

Citizen concern for the welfare of farm animals is well documented. However, there is a notable gap between people saying they want improved farm animal welfare and how they actually behave as a consumer. This is known as the citizen–consumer attitude–behaviour gap. As improvements in farm animal welfare can be affected by market demand, the choices consumers make become important. This paper introduces the concept of ‘nudging’ and discusses how it could be applied to reduce the attitude–behaviour gap amongst consumers. By designing the choice environment to better reflect the behavioural biases known to impact human decision-making, ‘nudge’ tools function to prompt individuals to make choices that are aligned with their stated intentions. Four ‘nudge’ tools: self-nudges, choice architecture, social norms and pre-commitments are discussed. The behavioural rationales for their use are reviewed and examples of how they might be applied to animal welfare provided. Improved farm animal welfare arguably requires improved pro-welfare consumer behaviour. This paper highlights how this might be encouraged by: self-nudging the salience of an ethical self-image; altering the choice architecture to influence decision-making; articulating social norms to impact behaviour; and using pre-commitment devices to overcome self-control issues.
