The adoption potential of alley farming as an agro-intervention system capable of providing fodder to small ruminant livestock in southern parts of Nigeria is evaluated in this paper. Data were collected from a total of 240 respondents through the use of structured questionnaire in some selected communities of the south-western (SW) and south-eastern (SE) parts of Nigeria where the agro-intervention had been introduced in the past. Data analysis showed that ownership of small ruminants is more popular among households in savannah zone than forest zone, and among current and former alley farmers than non-alley farmers with browse being the most preferred feed given to the livestock. The management indicators showed that the care of the animals is generally the responsibility of all family members. The data suggest that the introduction of alley farming to produce supplemental feed for livestock may not gain quick adoption in areas with local sources of browse notably in the forest zone. The paper then concluded that the introduction of alley farming to produce supplemental fodder may be an innovation more suited to livestock owners' needs in the mid-term future, rather than immediately.

Abstract Recent calls advocate that a huge reduction in the consumption of animal products (including dairy) is essential to mitigate climate change and stabilise global warming below the 1.5 and 2°C targets. The Paris Agreement states that to stabilise temperatures we must reach a balance between anthropogenic emissions by sources and removals by sinks of greenhouse gases (GHG) in the second half of this century. Consequently, many countries have adopted overall GHG reduction targets (e.g. EU, at least 40% by 2030 compared to 1990). However, using conventional metric-equivalent emissions (CO2-e GWP100) as the basis to account for emissions does not result in capturing the effect on atmospheric warming of changing emission rates from short-lived GHG (e.g. methane: CH4), which are the main source of GHG emissions by small ruminants. This shortcoming could be solved by using warming-equivalent emissions (CO2-we, GWP*), which can accurately link annual GHG emission rates to its warming effect in the atmosphere. In our study, using this GWP* methodology and different modelling approaches, we first examined the historical (1990–2018) contribution of European dairy small ruminant systems to additional atmosphere warming levels and then studied different emission target scenarios for 2100. These scenarios allow us to envision the necessary reduction of GHG emissions from Europe's dairy small ruminants to achieve a stable impact on global temperatures, i.e. to be climatically neutral. Our analysis showed that, using this type of approach, the whole European sheep and goat dairy sector seems not to have contributed to additional warming in the period 1990–2018. Considering each subsector separately, increases in dairy goat production has led to some level of additional warming into the atmosphere, but these have been compensated by larger emission reductions in the dairy sheep sector. The estimations of warming for future scenarios suggest that to achieve climate neutrality, understood as not adding additional warming to the atmosphere, modest GHG reductions of sheep and goat GHG would be required (e.g. via feed additives). This reduction would be even lower if potential soil organic carbon (SOC) from associated pastures is considered.

Small Ruminant Lentiviruses

Small Ruminant Lentiviruses (SRLV) are highly prevalent retroviruses with significant genetic diversity and antigenic heterogeneity that cause a progressive wasting disease of sheep called Maedi-visna. This work provides a systematic review and meta-analysis of the last 40 years (1981–2020) of scientific publications on SRLV individual and flock prevalence. Fifty-eight publications and 314 studies were included. Most articles used a single diagnostic test to estimate prevalence (77.6%), whereas articles using three or more tests were scarce (6.9%). Serological tests are more frequently used than direct methods and ELISA has progressively replaced AGID over the last decades. SRLV infection in sheep is widespread across the world, with Europe showing the highest individual prevalence (40.9%) and being the geographical area in which most studies have been performed. Africa, Asia, and North America show values between 16.7% to 21.8% at the individual level. South and Central America show the lowest individual SRLV prevalence (1.7%). There was a strong positive correlation between individual and flock prevalence (ρ = 0.728; p ≤ 0.001). Despite the global importance of small ruminants, the coverage of knowledge on SRLV prevalence is patchy and inconsistent. There is a lack of a gold standard method and a defined sampling strategy among countries and continents.

Early Pottery

A case study of the Neolithic comb ceramic site Pezmog 4 of the Kama culture presents a situation when results of radiocarbon dating change long-existing concepts concerning the development of archaeological events. Until the early 2000s, the chronology of the Kama culture, distributed mainly in the Kama and Vychegda River basins, has been based on comparative-typological analysis. Estimates of the age of this culture changed from the 3rd millennium BC in the 1950s to the 1st half of the 4th millennium BC by the 1990s. Research concerning the Pezmog 4 site in the central Vychegda River basin in 1999–2002 has abruptly changed this chronological understanding. The data obtained put the age of the early stage of Kama culture within the time range 5750–5620 cal BC and allowed us to propose the existence of another way of early pottery distribution in the forest zone of eastern Europe at the beginning of the 6th millennium BC. This innovation probably penetrated from the trans-Ural region.

A study was carried out to identify species used as fodder by small ruminant farmers in the selected villages in the Komenda‐Edina‐Eguafo‐Abrem district of the Central Region of Ghana. Livestock farmers in fifteen communities were interviewed using questionnaires to obtain information on the personal background and livestock feeding and management practices. The main aim of the study was first to identify existing browse species and to determine problems associated with the use of those existing browse species. Some problems identified include harboring of insects, causing of abortion as well as causing bloat. The survey showed that Ficus exasperata, Ficus umbellate, Baphia nitida, Griffonia simplifolia, Antiaris africana, Terminalia catappa, Grewia carprinifolia, Pethecellobium dulceand Leucaena leucocephala were the main browse species that were used in the district to feed small ruminants. Other feedstuffs that were used in feeding animals such as Aspillia africana and Manihot esulentus tops (leaves and peels) were also identified. The level of browse usage showed that Ficus exasperata had the highest value of 66.7% and Terminalia catappa had the lowest value of 13.3%. Farmers in the district preferred Ficus exasperata which they perceived to promote the best production response in livestock. Various reasons were assigned for the selection of a particular browse plant. Farmers in the district may have to be helped to cultivate browse plant in order to sustain the availability and usage of  browse for livestock feeding due to the rateof destruction of browse (shrubs and trees) resulting from urbanization, use of stem of shrubs and trees for fuelwood and other livelihood activities and desertification arising from human related activities.

Natural pasture for small ruminants must be sustained, enhanced, and where it has been diminished or destroy, restored, if animal production must contribute meaningfully to national food security. In Eastern Nigeria, farming system, such as bush fallow, are generally based on shifting cultivation. Unfortunately, agricultural lands are relatively scarce, thereby resulting to shortened fallow periods and thus, widespread diminishing and destruction of natural pasture. The urgency of managing deficient and scarce natural pasture in this environment is widely recognized. Not only is this essential for small ruminants’ feeding, but a dynamic animal sector is a key to achieving food security. The paper argues therefore, that alley farming is the right approach to managing deficient and scarce natural pasture, since it is the most promising alternative to traditional slash-and-burn shifting cultivation. Ikwuano Local Government Area of Abia State was used as the study area. The results show that there is a pressing need for alley farming promotion. Small holders’ access to this technology would aid in revolutionizing animal production in Nigeria. This paper advocates for policies that will incorporate alley farming into production recommendations transferred to small farmers.

Peste-des-petits-ruminants virus (PPRV) causes a severe respiratory disease in small ruminants. The possible impact of different atypical host species in the spread and planed worldwide eradication of PPRV remains to be clarified. Recent transmission trials with the virulent PPRV lineage IV (LIV)-strain Kurdistan/2011 revealed that pigs and wild boar are possible sources of PPRV-infection. We therefore investigated the role of cattle, llamas, alpacas, and dromedary camels in transmission trials using the Kurdistan/2011 strain for intranasal infection and integrated a literature review for a proper evaluation of their host traits and role in PPRV-transmission. Cattle and camelids developed no clinical signs, no viremia, shed no or only low PPRV-RNA loads in swab samples and did not transmit any PPRV to the contact animals. The distribution of PPRV-RNA or antigen in lymphoid organs was similar in cattle and camelids although generally lower compared to suids and small ruminants. In the typical small ruminant hosts, the tissue tropism, pathogenesis and disease expression after PPRV-infection is associated with infection of immune and epithelial cells via SLAM and nectin-4 receptors, respectively. We therefore suggest a different pathogenesis in cattle and camelids and both as dead-end hosts for PPRV.
