An experiment was carried out to compare the use of fresh cactus with cactus ensiled with and without a microbial inoculant in sheep diets by examining their feed intake, nutrient digestibility, nitrogen balance, and microbial protein synthesis and counting fecal enterobacteria. Twenty uncastrated mixed-breed sheep at approximately six months of age, with an average initial weight of 23.48 ± 2.40 kg, were used in the study. The animals were assigned to four treatments [fresh spineless cactus processed twice daily at the time of supply (FC2); fresh spineless cactus processed only once, in the morning, and supplied twice daily (FC1); spinelesscactus silage without inoculant (CS); and spineless-cactus silage with microbial inoculant (CSI)] in a completely randomized design with five replications per treatment. The experimental period was 21 days. The use of spineless cactus in the form of silage (CS and CSI) resulted in higher (P < 0.05) intakes of dry matter, organic matter, neutral detergent fiber, ether extract, non-fibrous carbohydrates, and total digestible nutrients; and higher digestibility coefficients of dry matter, organic matter, and total digestible nutrients. Lower counts of fecal enterobacteria were also observed with the ensiled cactus. By contrast, the diets did not influence (P> 0.05) nitrogen balance, microbial efficiency, urinary nitrogen losses, or fecal nitrogen losses. Regardless of inoculation, the ensiling of spineless cactus improves the sanitary quality of the diet, reducing the amount of enterobacteria in the cactus and resulting mainly in improved nutrient intake by sheep.

Assessing how much management of agricultural landscapes, in addition to protected areas, can offset biodiversity erosion in the tropics is a central issue for conservation that still requires cross-taxonomic and landscape-scale studies. We measured the effects of Amazonia deforestation and subsequent land-use intensification in 6 agricultural areas (landscape scale), where we sampled plants and 4 animal groups (birds, earthworms, fruit flies, and moths). We assessed land-use intensification with a synthetic index based on landscape metrics (total area and relative percentages of land uses, edge density, mean patch density and diversity, and fractal structures at 5 dates from 1990 to 2007). Species richness decreased consistently as agricultural intensification increased despite slight differences in the responses of sampled groups. Globally, in moderately deforested landscapes species richness was relatively stable, and there was a clear threshold in biodiversity loss midway along the intensification gradient, mainly linked to a drop in forest cover and quality. Our results suggest anthropogenic landscapes with high-quality forest covering >40 % of the surface area may prevent biodiversity loss in Amazonia. |
