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.

This research aimed to assess the social and environmental impacts of canola on the biodiesel production chain, as well as to analyze sustainability indicators in a reference term were canola is produced in the Passo Fundo region, state of Rio Grande do Sul, Brazil. Methodology included extensive literature review and application of two impact assessment tools: a) an Eco·certification system for rural activities (Eco·certRural) with 24 criteria for evaluating production chain impacts, based on the input of 15 experts knowledgeable on the diverse segments of the biodiesel chain in the region of the study, and b) a System for weighted environmental impact assessment of rural activities (APOIA-NovoRural) with 62 indicators based on detailed interview and field analyses with a canola- producing farmer. The assessment led to the conclusion that in the Passo Fundo region the biodiesel production chain based on canola brings mostly positive impacts on the environment and for the livelihood of people involved in its production. Since it increases the use of farming inputs and off-farm resources, the aspects related to input and resources demands were less favorable. Canola production brought important contributions for the sustainability of the reference farm, with a general index of 0.77 (in a 0 to 1.0 utility scale). |
