Abstract: The study of livestock in farming systems research (FSR) presents several challenges. Factors such as the small number of observations, high statistical variability in both experimental and non-experimental factors, and the difficulty in valuing non-market inputs and outputs make it difficult to evaluate on-farm trials. The willingness-to-pay (WTP) technique is proposed to complement other techniques for evaluating on-farm trials, such as linear programming, cost-benefit analysis, and partial budgeting. The farmer's WTP is a broad measure of the farmer's assessment of a technology's value, based on his perception of its effect on the production system, its social acceptability, and his attitudes toward risk. It is a particularly useful technique in the early stages of a trial when the amount of physical data may be insufficient for an assessment of the technology. Experience in Brazil showed the WTP method to be an inexpensive but effective technique for evaluating on-farm livestock rials, while enhancing farmer feedback. |

The study aimed to determine the optimal ratio for the mixture of forage cactus and corn stover silage, emphasizing the evaluation of fermentative profile, microbial populations, dry matter losses, chemical composition, and aerobic stability. A completely randomized design with four treatments and five replications was employed in this study. Treatments included varying proportions of forage cactus in corn stover at ensiling (0%, 10%, 20%, and 40% of fresh matter). After a 100-day fermentation period, the assayed variables underwent regression analysis. Forage cactus inclusion led to linear dry matter and ether extract reductions, with crude protein showing a negative quadratic effect (p < 0.05). The pH and water-soluble carbohydrates exhibited negative quadratic effects with the increasing proportion of forage cactus (p < 0.05). Lactic and acetic acids exhibited quadratic effects, reaching their peaks at approximately 20% forage cactus (p < 0.05). Lactic acid bacteria demonstrated a linear decrease, while yeasts/molds displayed a negative quadratic effect (p < 0.05). Dry matter losses followed a quadratic pattern, with the minimum values observed at 20% forage cactus (p < 0.05). Additionally, the inclusion of forage cactus significantly enhanced aerobic stability (p < 0.05). The incorporation of 20% forage cactus into corn stover silage markedly improved its quality. |
