Extract

Approximately 80% of all production costs are related to the purchase of forages and other feeds in dairy enterprises in Mexico. Resource poor, smallholder (campesino) systems are heavily reliant on the use of maize stover, noncultivated/cultivated grass species and weeds to feed their dairy cattle, thus a nutritional understanding of local forage resources would be of considerable economic benefit. The objective of this study was to develop predictive models of herbage production and nutrient composition of four non-cultivated pastures (NcP), in order to minimise the cost of sample analysis and improve the utilisation of local forage resources in dairy enterprises.
