Mexico is the major global producer of cactus prickly pear fruit, harvesting 510,000 tonnes per year. Insufficient technology to bridge the gaps on production chain halts this agroindustry to reach its full potential. Hand harvesting of cactus fruit is greatly inefficient; it is slow and expensive, field conditions are arduous, unsafe and risky. Ca...
Rising agrarian raw material prices in 2006 had a negative impact on the biogas sector in Germany, leading to the search for potentials for optimisation of production. A problem is the workload of the block-type thermal power station (BTPS). This is caused by biogas process disturbances, construction errors, technical problems and management mistak...
Although farm size may make a difference in access to all precision agriculture techniques, farms including small-scale traditional crop cultivation will likely have access to some of them in the long term. For this farm sector, a mathematical model is being developed to assist decision-making for improved dosage of nutrients and pesticides for cro...
In Mexico there is a wide contrast of farming activities. Much of farmland (5,574,770 ha) is cultivated by small farmers (2,243,138 holdings with < 5 ha), yet, some regions are already highly mechanised, and in other areas machinery contract services are available to farmers. To meet the demands for increased crop production it is necessary for the...
Title of the paper: Effect of different time of pre-milking teat preparation on milking characteristics of dairy cows in Cuba
For the evaluation of different times of pre-milking teat preparation on milking ability of different races/genotypes some parameters about milking with machines (milking characteristics) have been registered. This study rev...
For the evaluation of different times of pre-milking teat preparation on milking ability of different races/genotypes some parameters about milking with machines (milking characteristics) have been registered. This study reveals that an insufficient pre-milking teat preparation clearly under 60 s lead to a significant deterioration of the milking c...
The performance of a rear wheel drive and a front wheel assist tractors was determined under identical operating conditions. Both tractors were of the same model and trademark. The tractors were instrumented in order to determine the drawbar pull and travel speed on stubble soil and fresh ploughed soil. The two wheel drive (TWD) was tested with a 3...
El proceso de producción de la leche de cabra debe ser realizado con tecnología similar a la utilizada en la ordeña de vacas en sistemas intensivos. En años recientes, la leche de cabra ha adquirido nuevos adeptos; la leche fresca la consumen personas con alergia a la leche bovina o con problemas por el tamaño de la partícula grasa, y con la leche...
After being displaced, natural fibers industry is competing again with plastic products for a share of the market. Fiber from lechuguilla (ixtle) is exported to countries in Europe, Asia, North and South America. This material is used to manufacture a wide range of products such as brushes used for polishing of metals, filling for furniture and car...
Agricultural mechanization in Mexico still ranges from hand tools, tools for draught animals to mechanized equipment. Agricultural production concentrates on cereals for domestic consumption, where big machines, tillage tools, planters, fertilizing and spraying equipment have reached a high level of development. At present the mechanization index i...
La industria de fibras duras ha recobrado terreno despues de ser desplazada por los productos plasticos. La fibra de lechuguilla (ixtle) se exporta a paises de Europa, Asia, Norte y Sudamerica. Este material se utiliza para elaborar varios productos de uso industrial como cepillos para pulir metales, relleno de muebles y asientos, tapetes, alfombra...
In farming dry areas, where production units are small (1 to 5 ha), draught animals are the main source of power for agricultural labor in the production of crops of maize and bean. For tillage of the soil, plows are used; they are machines that turn the soil, and in consequence humidity is lost through evaporation and its physical properties are a...
From an economic point of view and in order to achieve a sustainable environment it is necessary to plan and to carry out recycling for a product through its different live stages. It is convenient to start since production is taking place, usage time and when it is being
