The objective was to estimate the production costs and profitability of maize silage and maize stubble as a feeding strategy for cattle in dry seasons in the southern region of Estado de México. Methodology:30 semi-structured surveys with non-probabilistic sampling were applied during the spring/summer 2020 cycle. Socioeconomic variables, the profitability threshold and the benefit/cost ratio were analyzed. The production units were characterized as small, the average age of producers did not exceed 45 years and nine years dedicated to production. Results: The average production of maize silage and maize stubble was 28 and 7.20 tons with a cost of 1,278.40 and 3,587.23 pesos per ton. Conclusions: The benefit/cost ratio in maize silage and stubble was 0.46 and 0.16. The conclusion is that both activities were profitable with a predominance of maize silage.
The objective of this project is to develop various personal care and food products using natural extracts of regional plants, which reduce the impact caused by Aedes aegypti. As of December 2018, the advances that were made consist of the development of a repellent patch prototype, two cutaneous spray products, hand soap, and an incense. The plants used are Ricinnus comunis, Artemisia ludoviciana, Cymbopogum citratus, Cucurbita maxima, Coffea arabica and Syzygium aromaticum. After conditioning, extracts were obtained using organic solvents.
