This work was part of the EU RobustMilk project. In this work package, we have focused on two aspects of robustness, micro- and macro-environmental sensitivity and applied these to somatic cell count (SCC), one aspect of milk quality. We showed that it is possible to combine both categorical and continuous descriptions of the environment in one analysis of genotype by environment interaction. We also developed a method to estimate genetic variation in residual variance and applied it to both simulated and a large field data set of dairy cattle. We showed that it is possible to estimate genetic

Abstract. A model was developed and incorporated into the Integrated Farm System Model (IFSM, v.4.3) that simulates important processes occurring during windrow composting of manure. The model, documented in an accompanying article, predicts changes in windrow properties and conditions and the resulting emissions of C and N. Our objective in this article was to evaluate the performance of the compost windrow model. Model predictions were compared to published data from an independent cattle manure composting study that characterized static (no turning) and turned windrows composted over a 188-

Road ecology has traditionally focused on the impact of in-situ and functional roads on wildlife. However, road construction also poses a major, yet understudied, threat and the implications for key aspects of animal behaviour are unknown. Badgers (Meles meles) have been implicated in the transmission of tuberculosis to cattle. There are concerns that environmental disturbances, including major road construction, can disrupt badger territoriality, promoting the spread of the disease to cattle. To address these knowledge gaps the ranging behaviour of a medium-density Irish badger population was

Abstract Public awareness of the importance of animal protein makes meat as one of the livestock products that is increasingly in demand. Beef cattle are one of the most popular livestock in the livestock sector. The ability of beef cattle to produce meat in both quality and quantity is influenced by genetic and environmental aspects. Environmental aspects that influence are maintenance, feed, reproductive management and health. One of the efforts to increase beef cattle productivity is through disease control.

Eutrophication resulting from phosphorus (P) accumulation in water systems has been a worldwide concern for three decades. Agricultural soils are known to be an important non-point source of P in waterways. The objectives of this research are to identify agricultural management practices that reduce the risk of P loss from soils, and to investigate the underlying mechanisms of P retention and loss from soils. In the short term (4 years), dissolved P loads were not affected by tillage and were similar in corn (in a continuous corn rotation) and soybean (in a soybean/corn rotation) production sy

The study was designed to test the hypothesis that P excretion in manure of dairy cattle could be reduced by manipulating electrolyte balance of the diet. Feces was the main route of P excretion, but fecal P was not affected by dietary cation-anion (DCAB) (P > 0.05). Plasma concentration of P tended (P < 0.10) to be higher at lower DCAB levels, implying that DCAB may have influenced P homeostasis. The overall P balance was not affected by the different DCAB levels. The range of DCAB where both P excretion and animal performance could be optimised is very narrow (+250 to +350 mEq/kg DM),

More intensive production of hogs and cattle in Quebec during the past decade has benefited local economies, but led to over-fertilization of agricultural soils and eutrophication of waterways. Provincial ministries responded to this issue by developing regulations to control manure applications. The objective of this thesis was to determine the environmental risk associated with applying farm manure in the late fall. Spreading manure in fall after harvesting corn was a common practice for many agricultural producers in Quebec, but this period is now viewed as very risky, having more negative

This thesis examines the responses of non-indigenous pastoralists in Central Australian rangelands to two social movements that profoundly challenge their occupancy, use and management of land. Contemporary environmentalism and Aboriginal land rights have both challenged the status of pastoralists as valued primary producers and bearers of a worthy pioneer heritage. Instead, pastoralists have become associated with land degradation, biodiversity loss, and Aboriginal dispossession. Such pressure has intensified in the 1990s in the wake of the native Title debate, and various conservation campai

Against this background, climate change adaptation is conceptualized as strategic agency in the field of risk-laden livelihood environments, that is, agency in the face of risky options and non-calculable uncertainties.The chapter conceptualizes pastoralists’ livelihoods exposed to a four-fold hierarchy of environmental risks and forces defining the actors’ arena of strategic decision making: From the global scale of ever extending impacts by the climate change imperative, to the national scale of government policies in terms of decentralization, challenging people to govern and define their communal efforts in terms of climate change adaptation, and down to the regional scale, which in the presented case is dominated by a large-scale investment, the Kuraz Sugar Development Project, which again confronts local actors with adverse forces toward villagization and eviction from pasture grounds.

A paradigm shift in the management of bacterial diseases of food animals is needed; a shift from pharmacologic interventions to disease risk identification and mitigation. The interaction between disease and its risk factors follows the disease triangle, a conceptual model that incorporates host, pathogen, and environmental factors as a tool to understand different aspects that influence disease. A sustainable approach to bacterial disease mitigation in production settings includes a comprehensive assessment of host, pathogen, and environmental factors of disease to build a prevention platform for multiple syndromes of bacterial disease in cattle. Using bovine respiratory disease as a model, the current chapter will focus on the state of the art of disease prevention in dairy cattle, and investigations into interactions between the host, environment and pathogen which can provide robust information on which to build a prevention platform for multiple syndromes of bacterial disease in cattle.

African animal trypanosomiasis (AAT) is a major constraint to livestock productivity, particularly in cattle and in camels. This chapter covers some general aspects of the arthropod vectors of animal trypanosomiasis, the tsetse flies Glossina spp., and to a lesser extent the biting flies. This chapter covers the classification, morphology, basic biology, and the eco-distribution of tsetse flies. The role of tsetse flies in disease epidemiology has also been reviewed. The elementary biology of these vectors is quite well known and elucidated. However, with advances in molecular and other biological techniques, new insights related to tsetse biology have been obtained. This chapter will revisit these basics and include some updated information emanating from research done in the recent past. The final part of the chapter is devoted to a brief discussion on biting flies, the vectors of T. evansi, which causes camel trypanosomiasis.

This chapter aimed to discuss population, meat production, and quality characteristics of camels. Camels are considered environmentally friendly and well adapted to the desert's harsh arid and semiarid environment due to their high movability, adequate fodder demand, and water regulation. Camels are most populous in the East Africa and Middle East. Although approximately 250,000 camels are annually slaughtered in many countries and camels as a producer of meat is becoming much more significant, camel meat market has not yet developed. In 2019, the global camel meat production in Africa was leading with 419,933 tonnes production, followed by Asia (210,000 tonnes) and Europe (179 Tonnes). An important feature that characterizes camelid meat products is the low level of intramuscular and subcutaneous fat compared to red meat sources. Pre- and post-mortem factors should be carefully considered to improve camel meat quality characteristics. According to the health aspects and quality of camel meat, it can be successfully marketed alongside cattle, dear, sheep, and goat.

Management factors affecting dairy calves have broad impacts on behavioral development and implications for long-term welfare, and research in this area is increasingly focused on understanding the behavioral needs of the calf, to refine management and improve understanding of welfare. In this chapter, we summarize recent research addressing behavioral needs of pre-weaned calves and post-weaned heifers, encompassing aspects of social interactions and feeding, rest and comfort, and opportunities for other behavioral expression. In general, evidence suggests welfare and performance benefits of accommodating more natural behavioral expression, including social contact, higher milk intakes fed via a teat, dietary variety, and space and resources to accommodate preferred activities, such as grooming and play. Throughout these sections, consequences of restricting these behaviors includes development of abnormal oral behaviors. Emerging themes of this area of research include consideration of individual differences and implications and approaches to accommodate broader behavioral expression through increasing environmental complexity.

Approximately one third of dairy cows are replaced every year. Replacement of dairy cattle is an important part of the cost of dairy production and an environmental sustainability concern. Primary culling reasons are reduced health and fertility. Reduced welfare often proceeds culling. This chapter focuses on factors that affect replacement and culling in dairy herds with a focus on cows. The act of culling is simple, but the risk factors and economic considerations are complex. The chapter first presents some data on culling risks and reasons, explores more in depth the effects of poor health on culling, and presents aspects of economic decision making regarding culling and replacement decisions.

Age estimation based on the dentition of animal remains is one of the most important methods used for analysis of the demography of past as well as contemporary animal populations by zooarchaeologists and wild game biologists (Wagenknecht 1967; Silver 1969; Morris 1972; Wilson et al. 1982). By constructing age profiles from faunal remains it is possible to study hunting of wild boar and pig husbandry in past societies (Higham 1967a; Rolett &amp; Chiu 1994; Vigne et al. 2000a; Magnell 2005a). Age estimation can also be used for assessing seasonal occupation of settlements and slaughtering of pigs (Legge &amp; Rowley-Conwy 1988; Rowley-Conwy 1993, 1998; Ervynck 1997). Several contributions to this volume provide good examples of how different aspects of the past relationship between humans and pigs can be understood from estimations of age. Age estimations based on tooth development have several advantages over ageing methods based on tooth eruption and wear. Experiments with undernourished pigs have shown that the tooth development is less affected by environmental factors than tooth eruption (McCance et al. 1961). A problem with age estimation of domestic animals based on tooth eruption is that the ages at eruption are known to vary between different breeds (Habermehl 1961; Silver 1969; Reiland 1978; Bull &amp; Payne 1982). The rate of tooth wear is also variable between, and within, different populations as a result of several factors such as variation in tooth morphology, eruption, coarseness, and abrasives in the diet (Healy &amp; Ludwig 1965; Grant 1978, 1982; Deniz &amp; Payne 1982; Magnell 2005b). However, tooth development seems to vary less between different populations. In cattle, roe deer, and red deer no consistent differences between various breeds/populations or between males and females have been noted in tooth development (Brown et al. 1960: 27; Carter 2001a). An advantage with age estimation based on tooth development is that the method considers several definable stages in the formation of all molariform teeth. Because the method is based on several characteristics in the dentition it is possible to give a very accurate assessment of dental maturity and the age of a specimen.

The importance of animal husbandry reaches all aspects (social, economic and environmental) of sustainable development in rural areas. People produce for sale, but also for consumption. At the same time, considering the location of this economic activity and the practice of farm technology, it is necessary to observe certain norms in order to ensure good environmental conditions. Of course, the future points to the mistakes of the past. Today, modern animal technology is coordinated through IT programs, which anticipate not only the production but also the risks.

Abstract Hot dip galvanized zinc coatings on steel structures are known to have superior atmospheric corrosion resistance properties compared to painted structures. However, the zinc coating can not be applied by this method on large steel structures. The protection of large steel structures against atmospheric corrosion is traditionally done by painting. The environmental pressure to eliminate solvent based paints has forced the painting contractors to move towards water based paints or completely rethink the coating process. One solution to this problem is to use arc sprayed zinc as the "pri

Conversion of citrus processing waste (CPW) generated during juice production into value added co-products is an important aspect of the juice industry as it offers a solution to waste disposal issues. Currently the practice of drying citrus waste to produce citrus pulp pellets (CPP) for use as cattle feed is profitable. However, until the recent rise in value, CPP value was marginal and often did not meet production costs. Another concern has been volatile organic emissions during CPP production. Only one third of the residual peel oil present in citrus waste is recovered during CPP productio

The agricultural operations in India are suffering from a serious problem of shortage of electrical power on one side and economic and effective disposal of agriwaste stuff on the other. India being agriculture based country, 70% of its main income (share in GDP) comes from agriculture sector. Any enhancement of income from this sector is based upon adequate supply of basic inputs in this sector. Regular and adequate power supply is one such input. But, the position of power supply in our country defies both these characteristics. With a major portion of power produced being sent to the indust

Abstract Recent interest in reducing stress on the food-energy-water (FEW) nexus requires the use of renewable, organic products that can subsequently address environmental sustainability concerns, such as mitigating greenhouse gas emissions. Pyrolysis-derived biochar from organic wastes (e.g., nutrient-rich agricultural wastes and leftovers, forest harvest residues, and cattle manure) and advanced feedstocks (e.g., algae) is capable of addressing ever-increasing global FEW concerns. Biochar water-nutrient holding capacity and carbon sequestration are key attributes for improving organic farmi

Southern Madagascar’s worst drought in 40 years had devastating cumulative effects on harvest and livelihoods. On top of this, frequent sandstorms and pest infestations have led to severe stress on vegetation triggering a drastic decline in rice, maize and cassava production. These environmental aspects, combined with a lack of livelihood diversification and ongoing poverty, the presence of cattle raiders and restrictive government decisions, have driven the population of southern Madagascar to acute food insecurity conditions. By December 2021, more than 1.6 million people were estimated to h
