Forage yield, nutritive value, ground cover and mineral concentration of 10 genotypes of Arachis spp. were evaluated over 3 years in Planaltina, Federal District, Brazil. Experimental plots were arranged in a randomized complete block design with 4 replications. Treatments were 5 genotypes of A. pintoi (accessions 2, 4, 5, 6 and 8), 2 genotypes of A. repens (accessions 1 and 7), 1 hybrid A. pintoi × A. repens (accession 3) and 2 A. pintoi cultivars, BRS Mandobi and Belmonte. All genotypes established well and achieved good ground cover in the first year. Cultivar Belmonte and accessions 2 and 4 produced the highest DM yields (means of 8.8, 8.5 and 8.8 t DM/ha/yr, respectively) throughout, while cv. BRS Mandobi and accession 6 were the worst (5.7 and 5.6 t DM/ha/yr). Most genotypes maintained ground cover above 80% throughout the study but cv. BRS Mandobi plus accessions 6 and 8 had declined to 60% or less by the third year. Mean crude protein concentration overall was 166 g/kg with a range of 154‒182 g/kg among genotypes. There was no major genotypic variation in mineral concentrations, which in all cases were considered marginal to adequate for tropical forage legumes. In conclusion, genotypes 2 and 4 (accessions BRA-039799 and BRA-039187, respectively) of A. pintoi are considered the most promising forage peanut options under the edaphoclimatic conditions of the experimental site. More effort is needed to improve seed set in these accessions to increase adoption by farmers. Their persistence under grazing and impact on production should also be demonstrated.

Resumo: Este estudo objetivou verificar as frações forrageiras selecionadas proporcionalmente por ovelhas em pastagem de caatinga através da micro-histologia fecal. Dezesseis ovelhas da raça Somalis brasileira, dividida em quatro tratamentos (0; 200; 350 e 500g de concentrado dia-1) foram acompanhadas durante o período das águas (abril), transição (junho) e seca (agosto). Do material coletado (plantas e fezes) foram preparadas lâminas de microscópio que serviram de referência para a identificação das frações (gramíneas; dicotiledôneas herbáceas e arbustivo-arbóreas) selecionadas. Foi verificado que no período das chuvas, predomina o consumo de dicotiledôneas herbáceas, enquanto no período seco, a vegetação lenhosa é a fração mais consumida pelos ovinos na caatinga. [Forage fractions selected by sheep in thinned and enriched caatinga with microhistology technique]. Abstract: This study aimed to determine the fractions selected by ewes in caatinga pasture through microhistology. Sixteen Somalis sheep split on four treatments (0, 200, 350 and 500 g day-1) were observed during the rainy (April), transition (June) and dry (August) season. From plants and feces collected, were prepared microscope slides used as reference material to identify grasses, herbaceous dicotyledons and shrubs and trees. Were observed to rainy season higher herbs intake, while in dry season, shrubs and trees was the fraction more consumed by sheep in caatinga. |
