This book explains how the phenomenal growth and industrialization of livestock production is a central part of the accelerating biophysical contradictions of industrial capitalist agriculture and of ongoing and future food crises.

Intensive cropping systems select for a low diversity of weeds tolerant of chemical control, leading to persistent weed‐crop competition and declining biodiversity. Crop rotation can mitigate this by introducing variable filters on the weed community through increasing management diversity. In this study, we investigate the effect of integrating livestock into no‐till crop rotations to complement chemical weed control. We analysed 12 years of weed seedbank data from a trial of eight rotation systems with different crop sequence diversities, of which four included grazed forage phases. Linear mixed models and ordination were used to assess how weed abundance, diversity, and community composition responded to management filters, defined in terms of levels of disturbance strength and diversity (grazing and herbicides), and resource availability and diversity (inorganic fertilizers, legumes, and manure). Grazed rotation systems had less herbicide applied than ungrazed rotation systems, and had the lowest weed abundance and highest weed diversity. Herbicides and grazing apply contrasting selection pressures on weeds, and this combination was more effective in reducing weed pressure than increasing herbicide quantity or mode‐of‐action diversity. Lower resource availability and higher nitrogen source diversity in grazed systems may have further reduced weed abundance and promoted diversity. Crop sequence diversity also reduced weed abundance and promoted weed diversity, indicating that variable crop‐weed interactions can enhance weed management. In addition, yields in the main cash crop (wheat) were highest where crop diversity was highest, regardless of whether the system contained grazed phases. Synthesis and applications. Diverse rotation systems produced high yields, and the inclusion of grazed forage phases maintained these yields at lower applications of herbicides and fertilizers: integrated livestock can therefore improve the sustainability of no‐till systems. The role of grazing as a filter imposing a contrasting selection pressure to other weed control options could be further explored to improve weed management in different farming systems.

This study conducts a review bringing together data from a large number of studies investigating energy use in EU livestock systems. Such a study has not been conducted previously, and improvements in our understanding of energy use concentrations in livestock systems will aid in developing interventions to achieve the EU’s 2030 and 2050 sustainability targets. The results from the Life Cycle Assessments included in this review indicate that energy use is concentrated in feed, housing, and manure management. In most systems, animal feed is the dominant energy use category. Regarding specific livestock categories, the studies covered indicate that energy use requirements range from 2.1 to 5.3 MJ/kg per ECM for cow milk, 59.2 MJ/kg for a suckler cow–calf, and 43.73 MJ/kg for a dairy bull, 15.9 MJ/kg to 22.7 MJ/kg for pork production, 9.6 MJ/kg to 19.1 MJ/kg for broiler production, 20.5–23.5 MJ/kg for chicken egg production. Our review indicates dominance of and dependence on fossil fuel and discusses the situation and research around transitioning towards renewable energy sources and improving energy efficiency. Our analysis indicates that existing energy use data in livestock systems are fragmented and characterized by multiple methodologies and considerable data gaps. In our view, there is a need for the development of a standardized methodology for measuring energy use in livestock systems, which we consider a necessary step to develop interventions that reduce fossil energy use in livestock systems and its contribution to climatic change.

Objective: This study aimed to evaluate the impact of extensive and intensive production systems on the carcass traits and meat quality of northern Moroccan goat kids from Bouhachem Park, Morocco. Materials and Methods: Nine 6-month-old male goat kids were reared extensively on mountain pastures in the Chefchaouen region (Bouhachem Park) before slaughter. Body weights and linear measurements were recorded, and comprehensive analyses were conducted to evaluate the nutritional, technological, and sensory characteristics of their meat. The findings were then compared with data from nine intensively reared male goat kids. Results: Extensively reared goat kids demonstrated significantly superior growth performance and carcass characteristics (p < 0.05). Their meat exhibited lower fat content (2.24 gm/100 gm vs. 5.23 gm/100 gm) and reduced cholesterol levels (28.87 mg/gm vs. 40.07 mg/gm) compared to meat from intensively reared goat kids. Additionally, the fatty acid profile was more favorable, characterized by a lower proportion of saturated fatty acids (45.77% vs. 47.48%), a higher polyunsaturated fatty acid content (16.85% vs. 8.72%), and an increased percentage of desirable fatty acids (72.84% vs. 70.52%). The semimembranosus muscle from extensively reared kids had significantly lower pH values (5.88 vs. 6.00). However, both outdoor- and indoor-raised kids showed acceptable meat color redness and shear force values. Sensory panel evaluations indicated a clear preference for extensively reared goat meat in terms of color, flavor, herbaceous aroma, and overall acceptability. Conclusion: Goat kids from Bouhachem Park pastures demonstrated promising results in growth performance, carcass traits, and meat quality. Their meat represents a valuable dietary option, offering high nutritional value and a superior sensory profile.

Livestock production is a major consumer of fresh water, and the influence of livestock production on global fresh water resources is increasing because of the growing demand for livestock products. Increasing water use efficiency of livestock production, therefore, can contribute to the overall water use efficiency of agriculture. Previous studies have reported significant variation in livestock water productivity (LWP) within and among farming systems. Underlying causes of this variation in LWP require further investigation. The objective of this paper was to identify the factors that explain the variation in LWP within and among farming systems in Ethiopia. We quantified LWP for various farms in mixed-crop livestock systems and explored the effect of household demographic characteristics and farm assets on LWP using ANOVA and multilevel mixed-effect linear regression. We focused on water used to cultivate feeds on privately owned agricultural lands. There was a difference in LWP among farming systems and wealth categories. Better-off households followed by medium households had the highest LWP, whereas poor households had the lowest LWP. The variation in LWP among wealth categories could be explained by the differences in the ownership of livestock and availability of family labor. Regression results showed that the age of the household head, the size of the livestock holding and availability of family labor affected LWP positively. The results suggest that water use efficiency could be improved by alleviating resource constraints such as access to farm labor and livestock assets, oxen in particular.

Mixed crop–livestock (MC–L) farming has gained broad consensus as an economically and environmentally sustainable farming system. Working on a Charolais-area suckler cattle farms network, we subdivided the 66 farms of a constant sample, for 2 years (2010 and 2011), into four groups: (i) ‘specialized conventional livestock farms’ (100% grassland-based farms (GF), n=7); (ii) ‘integrated conventional crop–livestock farms’ (specialized farms that only market animal products but that grow cereal crops on-farm for animal feed, n=31); (iii) ‘mixed conventional crop–livestock farms’ (farms that sell beef and cereal crops to market, n=21); and (iv) organic farms (n=7). We analyse the differences in structure and in drivers of technical, economic and environmental performances. The figures for all the farms over 2 years (2010 and 2011) were pooled into a single sample for each group. The farms that sell crops alongside beef miss out on potential economies of scale. These farms are bigger than specialized beef farms (with or without on-farm feed crops) and all types of farms show comparable economic performances. The big MC–L farms make heavier and consequently less efficient use of inputs. This use of less efficient inputs also weakens their environmental performances. This subpopulation of suckler cattle farms appears unable to translate a MC–L strategy into economies of scope. Organic farms most efficiently exploit the diversity of herd feed resources, thus positioning organic agriculture as a prototype MC–L system meeting the core principles of agroecology.

By making adoption decisions on soil conservation practices, agricultural producers play a key role in reversing unintended consequences caused by soil degradation. This paper studies two soil conservation practices—diversified crop rotation (DCR) and integrated cropping and livestock system (ICLS)—using survey data collected from Nebraska, South Dakota, and North Dakota producers. We estimate a bivariate probit model to identify factors affecting adoption decisions. Farmers' requirements for monetary incentives and values on soil health were found to be important determinants of adoption behavior. Geographic location matters, as North Dakota had the highest DCR adoption rate yet the lowest ICLS adoption rate.

While plains favorable to agriculture are still dominated by specialized and intensive agriculture, self-sufficient mixed crop-dairy farming systems increasingly attract policy makers' and scientists' attention. Owing to their limited use of purchased inputs, they can contribute to reducing the environmental impact of agriculture. Furthermore, self-sufficient farming tends to be linked with a search for autonomy in decision-making, i.e., farmers developing their own technical reference framework. Such farming systems can thus also contribute to alternative development pathways of rural territories. In this paper, we analyze how ten intensive mixed crop–dairy farms have progressively evolved toward more self-sufficient and autonomous systems. Through formalizing farmers' transition in action, we identified 34 tools that the farmers implemented making them reflect on their farming system, shift socio-professional networks, reorganize work routines, and steer the evolution of their production practices. For example, they created temporary pastures in crop rotation, introduced rotational pastures, observed their herds to adjust their feed and keep the animals in good health, and they limited expenditures to manage their cash flow. Which tools were used and when they were used depends on what is meaningful to them at various stages of the transition. Our analysis of transitions in action has three original features: it is centered on the transition as perceived by the actors who experience and manage it; it proposes a long-term conceptualization of the dynamics of farming systems, based on the farmer's initiative and creativity; and it highlights tools implemented by farmers during the transition to self-sufficiency and autonomy.

The mixed crop-livestock systems are acknowledged as sustainable due to its complementarity and synergy, contribution to welfare, food security, income, and poverty alleviation. The lack of efforts in the long-term impact for increased and more efficient food production, however, threatens the livelihoods and food security of smallholder producers. This paper provides a description on smallholder crop-livestock systems in the dominant system unit of crop and livestock production discretely subdividing in different agroecological zones (AEZs) into land-use land-cover class for considering factors influencing socioeconomic and agricultural intensification. A linear mixed-effects model was carried out to fit the relationship between the land-cover measurement and the corresponding farm enterprise in land use. The repeated measurements of linear predictors that fit in full and reduced model analysis were conducted in the system framework. The landscape slope (%), elevation (m) and market distance (minute) analysis were used in spatial adjustment in the specific system. The overall area of land-use system of the peasant holdings was 599.86 ha. The area covered by annual crops was 56%, which was higher (p < 0.01) compared to the area covered by natural pasturelands (17%), perennial crops (15%), vegetable (1%) and the tree or grass cover (2%). Distinct six farming systems were characterized, each being significantly different from other. The difference within a similar AEZ could probably be a result of a minor level of farm systems manipulation. The major difference associated could essentially be with a difference in agroecology and spatial variability of the farm households.

Background: Goat production has grown worldwide as a way to improve the quality of rural life and reduce the environmental footprint; nevertheless, there is a need to increase productivity through improved feeding strategies. The market demands healthier products with organoleptic characteristics similar to the traditional ones; thus, it is necessary to evaluate the effect of new forages for goats and its acceptance by consumers. Chemical and organoleptic composition of goat milk vary according to the diet which, in turn, affects the characteristics of cheese. Cheese texture, taste and smell are the most important sensory attributes for consumers. Objective: To evaluate the effect of substituting corn straw with sunflower hay associated with chickpea for dairy goats on yield, chemical composition and sensory acceptability of cheese, as well profitability. Methods: Twenty-eight Saanen dairy goats were randomly assigned to two treatments in a 30-day experiment on a small farm. The daily ration per goat in the MZST treatment (control treatment) consisted of alfalfa hay (200 g/goat/day) and concentrate (400 g/goat/day) plus 600 g/goat/day (50% of the ration) of corn straw. The SFCP treatment substituted corn straw with sunflower-chickpea hay; it had the same alfalfa and concentrate content, but with no corn straw and was added with 600 g/goat/day of sunflower-chickpea hay. The yield, composition and sensory evaluation of fresh cheese made with milk from each treatment were recorded, and the feeding costs and returns evaluated. Variables for the chemical composition of cheese were analyzed following a completely randomized design. Results: Significant differences were observed in cheese yield and all chemical composition variables. According to sensory evaluation, SFCP cheese had significantly higher scores for texture and odor but lower for taste and overall acceptability compared to MZST. In terms of profitability, SFCP increased feed costs by 5% but resulted in higher margins over feed costs of 12 and 24% for milk and cheese, respectively, compared to MZST. Conclusion: In spite of favorable performance and economic returns of MZST treatment (control treatment), the organoleptic characteristics of the cheese reduced its general acceptance.
