“…According to the occurrence of plants in the study area [22], plant species consumed by goats in sarcocaulescent scrublands [15, 16, 26], and families identified in the ruminal and faecal samples, we suggest some plants that could composite the diet of the lactating goats (Table S1). The ruminal samples suggest that lactating goats had consumed forbs of genera Eriogonum , Pterostegia , Vitis , Erythranthe , and Solanum ; native grasses (27 genera have been reported in the area), and other plant genera such as Aralia (tree) and Cneoridium (shrub).…”

“…This can mean a cyclical consumption pattern because rumen content represents foods eaten some hours before sampling, while faecal composition represents foods eaten longer before (~48 h) [1]. A ruminant behaves in a cyclical consumption pattern across days to cope with the chemical defenses of shrubs [17, 45], which are an abundant resource in the study area [25–27].…”

“…essential oils [6]). Thus, the Proteobacteria could be the most abundant phylum because the lactating goats graze in environments rich in secondary plant compounds as scrublands [55], where goats could consume Ambrosia and Aldama (Table S1) [16, 26] that contains essential oils and diterpenes [56, 57], respectively. This is also supported by Sphingomonas ( Alphaproteobacteria ) and Enterobacter ( Gammaproteobacteria ) presence in all ruminal and faecal samples and their great abundance in GRGua and GRPGo, and GRGua and GFCre, respectively.…”

“…Common shrubs and cactuses in the lowland scrubland are Jatropha cuneata , Ambrosia camphorata , Fouquieria diguetii , Jatropha cinerea , Cylindropuntia alcahes , Agave cerulata , and Bursera microphylla . Common species in the upland scrubland are A. camphorata , Cordia curassavica , Prosopis articulata , Aldama purissimae , and C. alcahes [25, 26]. Acaciella golmanii , Croton ciliatoglandulifer , Quercus oblongifolia , and Vachellia farnesiana are common species in the oak woodland, and P. articulata is the common species in the mezquital [22, 27].…”

Characterization of microbial communities from rumen and large intestine of lactating creole goats grazing in arid plant communities

Arid plant communities provide variable diets that can affect digestive microbial communities of free-foraging ruminants. Thus, we used next-generation sequencing of 16S and 18S rDNA to characterize microbial communities in the rumen (regurgitated digesta) and large intestine (faeces) and diet composition of lactating creole goats from five flocks grazing in native plant communities in the Sonoran Desert in the rainy season. The bacterial communities in the rumen and large intestine of the five flocks had similar alpha diversity (Chao1, Shannon, and Simpson indices). However, bacterial community compositions were different: a bacterial community dominated by Proteobacteria in the rumen transitioned to a community dominated by Firmicutes in the large intestine. Bacterial communities of rumen were similar across flocks; similarly occurred with large-intestine communities. Archaea had a minimum presence in the goat digestive tract. We detected phylum Basidiomycota, Ascomycota, and Apicomplexa as the main fungi and protozoa. Analyses suggested different diet compositions; forbs and grasses composed the bulk of plants in the rumen and forbs and shrubs in faeces. Therefore, lactating goats consuming different diets in the Sonoran Desert in the rainy season share a similar core bacterial community in the rumen and another in the large intestine and present low archaeal communities.

“…However, goat breeding has a poor reputation in environmental terms. At the international level, many research papers show that intensive goat browsing reduces vegetation cover [18][19][20][21][22] and inhibits the regeneration of fodder species [23,24]. Goat browsing can also reduce biomass production and plant diversity [21,25,26].…”

Goat Breeding: A Possible Sustainable Way to Manage Xerophytic Thickets in Southwestern Madagascar

Spiny thickets or xerophytic thickets (XTs) are a type of shrubby vegetation found in the far south and southwest of Madagascar, the driest parts of the island. This type of vegetation, which is rich in endemic animal and plant species, is endangered. Extensive local goat breeding (Capra hircus, for meat and milk production) based on XT browsing is an important source of household income. The aim of this paper is to analyse the possibility of using improved goat breeding as an alternative to wood charcoal (WC) production and slash-and-burn agriculture (SBA), which are unsustainable activities. The literature on (i) the impacts of SBA, WC production, and goat browsing on the XT ecosystem and (ii) the income provided by these three activities is reviewed to determine the sustainability level of improved goat husbandry. SBA and WC production reduced XT biomass and XT cover area, while goat browsing alone, at a stocking rate of one head per hectare, did not affect XT leaf biomass production and shrub regeneration. Furthermore, batch breeding and flushing techniques provided the highest annual income, mainly from the sale of surplus animal products. This improved goat husbandry may be a sustainable alternative to WC production. However, increasing the current stocking rate is necessary to surpass the combined income of WC production and SBA. An estimation of the XT carrying capacity would offer a basis to assess whether this ecosystem would support a higher stocking rate.
