Seasonal dynamics of forage nutrition in smallholder goat production systems in Malawi

Forage and browse are a valuable natural resource in Malawi that can be used to support livestock production which, in turn, can contribute towards delivering income and nutrition to households and communities. However, the quality and quantity of forages can be poor, especially during the dry season. The objective of this study was to assess the nutritional composition of naturally available forages across smallholder livestock systems in Malawi, with particular focus on seasonal differences in quality and quantity. Samples of herbaceous forages and browse were collected over 17 months, across four sites (30 farms/smallholders) in central Malawi. Forages underwent nutritional analysis for crude protein, fibre and ash/organic matter. NDVI obtained from satellite imagery was used as a proxy for forage availability. Forage nutrition and availability were most adequate in the wet season, with higher concentrations of crude protein and a greater availability of herbaceous plants. There were significant differences in low-digestibility fibre fractions between locations, likely due to local factors such as soil and hydrology. The fall in crude protein concentrations from the wet season to the dry season along with a reduction in forage biomass represents a seasonal nutritional feed gap that may impact productivity within livestock systems.

Could Cratylia argentea replace Tifton 85 hay on growing and finishing lamb diets in tropical areas?

Legumes shrubs such as Cratylia argentea have an ability to thrive in environments with low water availability and poor soil. On the other hand, forage grasses such as Tifton 85 have a greater demand for inputs to be productive. The objective of this study was to evaluate the performance of growing and finishing Lacaune lambs fed Cratylia argentea hay as an alternative to Tifton 85 (Cynodon spp). Twenty-four Lacaune lambs aged between five and six months (average body weight [BW] 21.50 ± 3.38 kg) were arranged in a split-plot randomized block design. The plots consisted of different Cratylia to Tifton 85 hay proportions (0, 20%, 40%, or 100%, dry matter [DM] basis) as a roughage replacement in the total diet. The subplots represented two evaluation times, entitled "initial period" and "final period", which consisted of the early seven days of total feces and urine collection, and the last seven days of the experiment, respectively. The lambs were blocked by weight with six replicates per treatment. The results show that the level of Tifton 85 replacement for Cratylia hay in the roughage portion of the lamb diet did not influence (P > 0.05) weight gain (WG), dry matter intake or dry matter digestibility; feed conversion, feed efficiency; and the evaluated nitrogen balance variables. The digestibility coefficient of neutral detergent fiber decreased linearly as Tifton 85 replacement for Cratylia level was increased, which probably happened due to the presence of highly lignified material within the Cratylia hay. However, the alternative legume maintained animal performance of Tifton 85. In conclusion, Cratylia hay can be recommended as a potential substitute for Tifton 85 hay, which requires greater inputs for the production. Cratylia may be considered a feeding strategy for livestock production, especially for smallholder livestock systems and regions with unfavorable soil and climate.

Antimicrobial Resistance of Escherichia coli Isolates from Livestock and the Environment in Extensive Smallholder Livestock Production Systems in Ethiopia.

The objective of this study was to characterize the distribution of antimicrobial resistance (AMR) of Escherichia coli (E. coli) isolated from livestock feces and soil in smallholder livestock systems. A cross-sectional study was carried out sampling 77 randomly selected households in four districts representing two agroecologies and production systems. E. coli was isolated and the susceptibility to 15 antimicrobials was assessed. Of 462 E. coli isolates tested, resistance to at least one antimicrobial was detected in 52% (43.7-60.8) of isolates from cattle fecal samples, 34% (95% CI, 26.2-41.8) from sheep samples, 58% (95% CI, 47.9-68.2) from goat samples and 53% (95% CI, 43.2-62.4) from soil samples. AMR patterns for E. coli from livestock and soil showed some similarities, with the highest prevalence of resistance detected against streptomycin (33%), followed by amoxycillin/clavulanate (23%) and tetracycline (8%). The odds of detecting E. coli resistance to ≥2 antimicrobials in livestock fecal samples were nearly three times (Odd Ratio-OR: 2.9; 95% CI, 1.72-5.17; p = 0.000) higher in lowland pastoral than in highland mixed crop-livestock production systems. These findings provide insights into the status of resistance in livestock and soil, and associated risk factors in low-resource settings in Ethiopia.

Climate Change Impact on Small-Scale Animal Agriculture: Livestock Water & Food Security in Africa

Water is essential for food security and animal agricultural productivity, but it is becoming more scarce due to climate change. The interaction between climate change and livestock water resources has received little attention from researchers, despite the significance of small-scale animal husbandry for the rural poor in Africa and the size of the changes that are anticipated to have an impact on smallholder livestock systems. Threats to livestock water are undoubtedly one of the most significant environmental issues that have impacted food security on the continent, given their links to small-scale animal husbandry and the detrimental impacts on productivity. In order to balance the negative effects of climate change scenarios for sustainable animal productivity and contribute to food security through small-scale animal agriculture, the most climate-smart and resilient agricultural water practices and technologies must be used. Changes in rainfall and a decline in the biomass available for grazing and rangelands as a result of water stress brought on by the climate would have the most severe effects. This is due to the rain-fed nature of small-scale livestock farming. The local animal genetic resources are essential for animal productivity and food security in Africa, particularly in areas where livestock water is becoming scarce owing to climate change. Research and development goals on the effects of climate change on livestock water, animal productivity, and food security may need to be reviewed if demands of vulnerable small-scale animal producers are to be successfully addressed in the future decades. It is best to use an interdisciplinary approach to comprehend the relationships between small-scale animal husbandry, food security, and climate change. By navigating the complexities of climate adaptation, small-scale livestock farmers can manage livestock water scarcity by taking adaptation measures that are in line with evolving climate impacts and associated means of implementation based on pertinent and useful knowledge that takes into account a blend of traditional and modern water science. In this paper, an effort is made to close some significant information gaps and shed light on how water-induced stress impacts small-scale animal production, which has an effect on food security.

Living fences for improved smallholder livestock systems in Cambodia

ABSTRACT In northwest Cambodia, the majority of smallholder households own livestock. Poor consistency in feed supply throughout the year is a major constraint to livestock performance. Another critical challenge, livestock roaming in the dry season for forage, results in smallholders having few options to protect any post-rice dry season cropping activity from free-ranging animals. Living fences have the potential to address both these challenges, by providing high-quality feed for livestock throughout the year, while also serving as a barrier to protect the land from livestock grazing. A mixed-methods approach was used with communities in Battambang Province, including household surveys, a fodder production experiment, a cattle feeding trial, farmer training and data on dissemination and adoption. Results showed that living fence species, such as Leucaena leucocephala, can produce 2.5 kg of fresh weight per week per 100 trees during the dry season. This biomass volume is sufficient to supplement cattle diets so that a smallholder can sustain a small percentage weight gain in cows throughout the dry season. Critical challenges, including land tenure, physical access to paddy lands, and the gendered nature of these farming systems, remain for realizing private benefit on paddy lands culturally considered public in the dry season.

Gender disparities in poverty among smallholder livestock farmers in South Africa

ABSTRACT This paper analyses gender disparities in poverty and the determinants of poverty among smallholder communal livestock farmers across five provinces in South Africa. A combination of multi-stage and stratified sampling techniques were used to select 591 farmers across the provinces. The Foster, Greer and Thorbecke (FGT) poverty indices were used to determine the extent and severity of poverty among smallholder livestock farmers. The results of the FGT analysis revealed that poverty is prevalent among smallholder livestock farmers but more pronounced among female-headed households. A binary logit regression was used to determine the predictors of poverty among communal livestock owners. Factors such as level of education, gender of household head, access to markets and extension services reduce the probability of a household becoming poor. Conversely, factors such as household size and access to credit had a negative effect on household well-being. These results highlight the importance of strengthening institutions (extension, livestock farmer organisations and markets) to improve smallholder livestock systems. Further, the study recommends that agricultural extension services should integrate gender mainstreaming in interventions that target smallholder communal livestock farmers, and that rural development projects should focus on interventions that aim at diversifying farm income.

Reducing agro-environmental trade-offs through sustainable livestock intensification across smallholder systems in Northern Tanzania

ABSTRACT Livestock productivity in East Africa, and especially in Tanzania, remains persistently low, while greenhouse gas (GHG) emission intensities are among the highest worldwide. This mixed methods study aims to explore sustainable livestock intensification options that reduce agro-environmental trade-offs across different smallholder farming systems in Northern Tanzania. A smallholder livestock systems typology was constructed, and representative farms simulated with a whole farm multi-objective optimization model. Livestock contributed more than 90% of on-farm GHG emissions, and DAIRY had the lowest GHG emission intensity (2.1 kg CO2e kg−1 milk). All livestock systems had alternative options available to reduce agro-environmental trade-offs, including reducing ruminant numbers, replacing local cattle with improved dairy breeds, improving feeding through on-farm forage cultivation, and minimizing crop residue feeding. Three obstacles to adoption of these technologies became apparent: they require a skillful re-organization of the entire production system, result in loss of some multi-functionality of livestock, and incur higher production risks. Sustainable livestock intensification can be a key building block to Tanzania's climate-smart agriculture portfolio, providing synergies between productivity and income increases, and climate change mitigation as co-benefit. A better understanding of the institutional settings, incentives and coordination between stakeholders is needed to sustainably transform the livestock sector.

<i>Orelha de Elefante Mexicana</i> (<i>Opuntia stricta</i> [Haw.] Haw.) spineless cactus as an option in crossbred dairy cattle diet

new genotype of spineless cactus is being used in the diets of dairy cattle that are raised in semi-arid regions. However, little is known about its nutritional value. This study aimed to evaluate the effects of replacing Miuda (Nopalea cochenillifera Salm Dyck) with Orelha de Elefante Mexicana (Opuntia stricta [Haw.] Haw.) spineless cactus, on nutrient intake and digestibility, milk yield and composition, feeding behaviour, microbial protein synthesis, nitrogen balance, and ruminal and blood parameters of dairy cows. Ten Girolando cows, 500 ± 51.6 kg bodyweight, were distributed in a double Latin square design 5 x 5. The treatments consisted of replacement levels of Miuda (MIU) by Orelha de Elefante Mexicana (OEM) at 0, 25, 50, 75, and 100%. The intake and digestibility of dry matter (DM) (14.38–12.95 kg d-1, 716.3–658.9 g d-1), organic matter (OM) (13.01–11.43 kg d-1, 747.8–704.8 g d-1), crude protein (CP) (2.02–1.61 kg d-1, 863.8–845.2 g d-1) and total digestible nutrients (TDN) (9.38–7.92 kg d-1) decreased linearly with the increase in replacement. Despite the decrease in intake and digestibility, the supply of nutrients was sufficient to maintain a milk yield of 12.5 kg d-1. The average daily weight gain decreased linearly with the increase in replacement, while protein microbial efficiency (g microbial CP kg-1 TDN intake; 91.24 to 127.44 g kg-1) increased linearly. Thus, OEM could replace 100% MIU in diets with 48% of spineless cactus, for crossbred lactating cows with 12.5 kg d-1 milk yield. Therefore, OEM is a viable new option for producing milk in smallholder livestock systems in semi-arid regions.Keywords: Alternative forage, milk yield, ruminal parameter, semi-arid, smallholder livestock system

Productive and income contributions of sheep, goat, and cattle, and different diversification schemes in smallholder production systems of Northern Patagonia, Argentina.

Wool production oriented sheep keeping is the most important rural activity in Patagonia, Argentina, followed by goat and at a lower extent cattle production. The existing perception on the smallholder production systems from most decision makers (e.g., policy) is that they are marginal, with low productivity and have negative returns. Since the Argentinean economic scenario has changed drastically in the last decade, the aim of this study was to analyze the economic and productive contribution of different livestock species in smallholdings. The results showed that the post-1990's economic scenario turned most smallholder livestock systems to have positive economic performance, but there were still productive restrictions that limited to fully benefit from these favorable circumstances. Goats were the most profitable livestock due to their higher productive performance, followed by sheep and cattle, with poorer performances. A strong cooperation between the intervention programs and research institutions is recommended to overcome the current production bottlenecks, by focusing on cattle and sheep production systems.

Identification and analysis of smallholder producers’ constraints: applications to Tanzania and Uganda

This article puts forward a method for the analysis of constraints faced by developing countries’ smallholder producers. It is consistent with theories of constraints, efficient in terms of cost and researchers’ time, and accessible to a non-technical audience. A hybrid of workshop discussion and individual data collection, it also draws on data and analyses available in most developing countries. The article presents an application to smallholder livestock systems in Tanzania and Uganda, reporting results and analysis relating constraints to households’ characteristics and conditions, and their stated goals. While limitations are identified, it is proposed for application in other development fields.

Policy opportunities to enhance the role of smallholder livestock systems in Limpopo Province of South Africa

Post-apartheid administrations in South Africa were faced with redressing the legacy of multifaceted poverty and social inequalities created by apartheid politics. The entrance of smallholder farmers into the mainstream economy became a government priority and policy aim. Institutional efforts in Limpopo Province provided infrastructure to establish poultry and vegetable producing enterprises. Very few livestock projects were funded. The success rate of institutional interventions was low. We argue that smallholder livestock systems offer policy opportunities to realise post-apartheid reform goals in the smallholder livestock sector. The premises are; there are more livestock in communal smallholder sector than in the commercial sector. This indicates there is a substantial level of natural, human and social capital existing within smallholder livestock systems. Secondly, commercial livestock systems are increasingly converted to game and wildlife enterprises necessitating imports of large numbers of livestock from Namibia to account for the shortfall in red-meat in South Africa. It is possible that the low off-take characterising smallholder livestock and the Cattle Complex Philosophy probably deterred past efforts to recognise the potential of smallholder livestock systems for rural and agricultural development. The Cattle Complex Philosophy claims that African smallholders have an attitudinal resistance to sell livestock. Data from a survey amongst 193 households in ten villages of Sekhukhune District of Limpopo Province illustrates that low livestock sales relates to the dysfunctional composition, sub-optimal reproductive potential and high calf mortality of smallholder herds. Conclusions and policy recommendations are offered. Keywords: Smallholder, Livestock, Limpopo Province
