“…Another complication arising in the estimation of production functions is the interdependence between corn production and livestock farming, which can be attributed to various factors. Crop residues often serve as livestock feed during dry seasons [ 36 ], while corn is used as poultry feed. Furthermore, cattle manure is employed to enrich the soil and improve its quality [ 37 ].…”

Approaches to the estimation of shadow prices generally assume that all but one market function correctly. However, multiple market failures are common in developing countries. We present a theoretical model and an empirical strategy to estimate the shadow price of a subsistence good in an economy where labor markets fail. Our results show that: 1) among subsistence producers, the shadow price of this good must be greater than or equal to the market price, and equal to it for surplus growers; and 2) current methods create biases when the otherwise-perfect-markets assumption is violated. The propositions are tested using a representative survey for rural Mexico. We find that the shadow wage is below that of the market (MXN $93.2/day vs. MXN $132.3/day), and that the shadow price for subsistence corn is over ten times greater than its market price (MXN $32.37/kg vs. MXN $3.19/kg). Unbiased shadow price estimates for subsistence goods help to overcome the limitations of current income poverty measures: their overestimation of the purchasing power of subsistence households and their underestimation of the value of subsistence goods. In rural Mexico, current practice underestimates the population in food poverty by 2%; an additional 9% has income above the poverty line yet fail to meet the utilization dimension of food security.

“…In recent years, the resulting stubbles or residues from harvests have emerged as an alternative to feed livestock and decrease the production of enteric ruminal CH 4 (Caballero-Salinas et al, 2017). In addition, these residues tend to have a high fiber content, which represents an obstacle in the diet of humans, but not in that of ruminants.…”

“…In Mexico, one of the most common residues for bovine livestock feed is maize (Zea mays L.) stubble, which has considerable nutritional characteristics for the diet of ruminants (Prieto et al, 2016); in addition, maize stubble represents up to 40% of the total residue fodder in the dry season (Caballero-Salinas et al, 2017). This residue is offered to the animals as a dry fodder or in ensilage (Gómez-Gurrola et al, 2016).…”

Objective: To analyze the alternative sources of food for livestock production to mitigate greenhouse gas emissions in Mexico.Design/methodology/approach: A document archive analysis was carried out about the use of certain industrial and agricultural wastes in Mexico in the last decade, and how these can serve as an alternative source of animal feed; these offer certain chemical properties that promote the mitigation of greenhouse gas emissions in livestock systems and also generate an added value in the agricultural and industrial sector.Results: Agricultural and industrial production in Mexico generates an important amount of wastes that are not exploited; in parallel, livestock production in Mexico is growing exponentially, which demands a surface and consumption of natural resources. Therefore, agricultural and industrial residues in Mexico represent a potential alternative source of animal feed, which offers a reduction in the surface destined to the production of food for animals and gives an added value to the industrial and agricultural residues in the country.Study limitations/implications: The alternative sources of food adjust to the agricultural and industrial sectors.Findings/conclusions: The use of agricultural residues, industrial wastes, and other alternate sources of food is suggested as a sustainable alternative in the reduction of GHG in livestock systems and a contribution to the mitigation of climate change in Mexico.

Ecuador is an agricultural country, which has an actual production of starch obtained from cassava. Tuber processing residues do not have an economic impact; for example, the cassava bagasse, only used for plant fertilization and animal feeding. This project aimed to study the influence of the fermentation variables (pH and agitation), on the lactic acid production. Enzymatic hydrolysis of cassava bagasse starch for the varieties INIAP 650 and INIAP 651 was performed using α-amylase and glucoamylase. Then, glucose was fermented by Lactobacillus leichmannii ATCC 7830 strains, varying conditions such as agitation (150 rpm and absence) and pH (4.5, 5.0, and 5.5). Finally, the determination of lactic acid was performed by potentiometric and FTIR analysis. Conversions of cassava bagasse to reduced sugars were 71.66 and 85.05 % for INIAP 650 and INIAP 651 varieties. The best lactic acid concentrations were 27.62 and 33.48 g/L, obtained at pH 5.5 and agitation, for INIAP 650 and INIAP 651 varieties. Qualitative analysis conducted by FTIR spectrophotometry confirmed the presence of lactic acid in the reacted products. Lactic acid production from cassava bagasse starch could contribute to the Manabí and Esmeraldas provinces of Ecuador's economic development.
