Rumen Degradation Characteristics Of Four Species Of Native Pastures From Central Mexico In Three Growing Periods, A. A. Rayas, A. M. J. Espinoza‐Ortega, J. G. Estrada‐Flores, C. Arriagal, F. Mould, O. A. Castelán-Ortega Jun 2023

Rumen Degradation Characteristics Of Four Species Of Native Pastures From Central Mexico In Three Growing Periods, A. A. Rayas, A. M. J. Espinoza‐Ortega, J. G. Estrada‐Flores, C. Arriagal, F. Mould, O. A. Castelán-Ortega

IGC Proceedings (1997-2023)

The smallholder cattle systems of the Toluca valley in central Mexico are based on the use of maize and native grasses. Research has been devoted to nutritional characterisation of improved pastures, but native species of grasses have not been studied, despite their importance. The aim of this experiment was to evaluate the in vitro rumen degradation kinetics of four species of native pastures.


Action Plan For The International Year Of Rangelands And Pastoralists (Iyrp): The Case For The United States, Canada, And Mexico, Barry Irving, Larry Howery, Jürgen Hoth, Jess Peterson Oct 2021

Action Plan For The International Year Of Rangelands And Pastoralists (Iyrp): The Case For The United States, Canada, And Mexico, Barry Irving, Larry Howery, Jürgen Hoth, Jess Peterson

The GAP analysis (A Case of Benign Neglect: Knowledge gaps about sustainability in rangelands and pastoralism) points to several gaps that are relevant to the US, Canada and Mexico. North American rangelands span the ecological continuum of polar to hot deserts and arid to humid climates that exhibit highly variable ecological and forage production potential across time and space. Although there is a great deal of rangeland research, extension, and inventory capacity in all three countries, a weak link is the dissemination of information to North American pastoralists (conventionally referred to as ranchers or producers). Although the extension system in …

Range Management Program: “Los Ángeles” Experimental Cattle Ranch In Northern México, Ricardo Vásquez, Silverio G. Pérez Apr 2020

Range Management Program: “Los Ángeles” Experimental Cattle Ranch In Northern México, Ricardo Vásquez, Silverio G. Pérez

IGC Proceedings (1997-2023)

The arid and semi-arid grasslands of both the ejidos (farming communities) and extensive (private) cattle ranches in northern México face serious degradation problems. This is visibly evident in the extent of soil erosion, loss of biodiversity and invasion of undesirable species (Ceballo et al. 2009). Severe impact of drought and over-grazing are important causes for the declining productivity now common place throughout these north Mexican grasslands. Two important contributing factors to this grassland degradation are: (1) the lack of continuous and well integrated education programs on the range and ranch management; and (2) a scarcity of government and private …

Small-scale dairy systems in Mexico represent over 78% of dairy farms and produce 37% of the nation’s milk, and have an important role in reducing rural poverty. Small-scale dairy systems are defined by having herds of 3 to 35 cows plus replacements, and rely mostly on the family for labour. In the central highlands, many small-scale dairy farms base the feeding of herds on irrigated cultivated pastures of ryegrass (Lolium multiflorum, L. perenne) – white clover (Trifolium repens), mostly under cut-and-carry by hand with scythes, straws, and large amounts of commercial compound concentrates that result in …
