The research investigated the effect of dietary supplementation with Artemia sp. enriched with the autochthonous probiotic Enterococcus faecium on growth performance, microbiota modulation, intestinal morphology, and resistance to pathogenic bacteria of Megaleporinus macrocephalus larvae. The study evaluated four treatments (C: without probiotics; T1: 1 × 104 ; T2:1× 106 ; and T3: 1 × 108 CFU·mL-1) in quadruplicates. The larvae (n = 160; weight = 5.3 ± 2.3mg and length = 3.73±0.4mm) were distributed in 16 L containers at a density of 10 larvae·L-1 for 20 days. The productive performance, survival, gut microbiology, and histology were measured. The larvae were also submitted to acute challenge against the pathogenic bacterium Aeromonas hydrophila. The results showed that supplementation with 1 × 108 CFU·mL-1 promotes greater gain in length (13.78 ± 0.40 cm) and total weight (0.08 ± 0.002 g), higher counts of lactic acid bacteria and lower total heterotrophic in the intestines (7.11±0.30; 0.12 ± 0.09 log CFU·g-1, respectively) and larger villi (0.26 ± 0.03μm). Diets containing probiotics influenced the animals’ resistance to acute infection, with a lower accumulated mortality in T3 (33% ± 11.54%) and a higher one in C+ (93% ± 11.54%). Thus, probiotic supplementation with the autochthonous bacterium E. faecium (1×108CFU·mL-1) provides zootechnical improvement, villus increase and greater resistance to infections.

O estudo avaliou quatro tratamentos (C: sem probióticos; T1: 1 × 104; T2: 1 × 106 ; e T3: 1 × 108 UFC·mL-1) em quadruplicata. As larvas (n = 160; peso = 5,3 ± 2,3 mg e comprimento = 3,73 ± 0,4 mm) foram distribuídas em recipientes de 16 L na densidade de 10 larvas·L-1 por 20 dias. Desempenho produtivo, sobrevivência, microbiologia e histologia intestinal foram medidos. As larvas também foram submetidas a desafio agudo contra a bactéria patogênica Aeromonas hydrophila. Os resultados mostraram que a suplementação com 1 × 108 UFC·mL-1 promoveu maior ganho de comprimento (13,78 ± 0,40 cm) e peso total (0,08 ± 0,002 g), maior contagem de bactérias lácticas e menor de heterotróficos totais nos intestinos (7,11 ± 0,30; 0,12 ± 0,09 log UFC·g-1, respectivamente) e maiores vilosidades (0,26 ± 0,03 μm). As dietas contendo probióticos influenciaram a resistência dos animais à infecção aguda, com menor mortalidade acumulada em T3 (33,33%±11,54%) e maior em C+ (93,33% ± 11,54%). Assim, a suplementação probiótica com a bactéria autóctone E. faecium (1 × 108 UFC·mL-1) proporciona melhora zootécnica, aumento de vilosidades e maior resistência a infecções.

The Caatinga Domain is exclusively Brazilian, covered by vegetation exhibiting a great diversity of species, which have morphological and physiological characteristics determined by environmental conditions. These attributes define quantity and quality litterfall deposition on the soil. The litterfall deposition seasonality was monitored a fragment of Caatinga vegetation, located in the semiarid region of Brazil, from 2016 to 2017. The decomposition rate, mean residence time for litterfall (50 and 95%), and the exportation of mineral nutrients via deciduous material were determined. Data from meteorological variables and litterfall were used in the elaboration of Pearson's correlation matrix, and multicollinearity, canonical and path analyzes. The Caatinga deposited on average 637 kg DM (dry mass) ha−1 year−1 litterfall, including 53% leaves, 26% twigs, 15% reproductive structures and 6% miscellanea, with deposition peaks between the months of March and July, with values above 57 kg MS ha−1. Global solar radiation, vapor pressure deficit, soil heat flux, rainfall and normalized difference vegetation index are controlling factors the litterfall deposition. The decomposition rate of the litterfall was 0.33 kg DM ha−1 year−1, while the time required for the disappearance of 50% and 95% of the litterfall was respectively 2.1 and 9.1 years, and the exportation of nutrients was 13.59 kg ha−1 year−1. Litterfall deposition was determined by the environmental conditions and physiological responses of the vegetation, which are fundamental to maintaining the Caatinga Domain.
