Naturally occurring salt tolerant and halophytic plants (trees, shrubs, grasses, and forbs) have always been utilized by livestock as a supplement or drought reserve. Salt tolerant forage and fodder crops are now being planted over wide areas. Increasingly, large-scale production of fodder on formerly abandoned irrigated cropland has allowed salt tolerant and halophytic feedstuffs to be mainstreamed into the supply chain for feedlots. Feeding salty feeds to livestock has been evaluated in many countries with good outcomes especially as a way to improve livestock nutrition and productivity. Better ways have been devised to use these potentially valuable feed resources. These feedstuffs are best fed in mixed rations. Substituting conventional fodder with up to 30 percent of the diets comprising halophytic feedstuffs have proved most successful for ruminant livestock but special formulations have been devised for poultry and rabbits. There are big savings on the import of costly feedstuffs and benefits to livelihoods of those dependent on scattered, sparse and unreliable forage/fodder in the world’s drylands that cover about 40 percent of the world’s land surface. This book is written by leading authorities from many different countries. It reviews past and current work on the animal-oriented aspects of the utilization of feedstuffs derived from salt tolerant and halophytic plants. It brings to the reader (scientist, researcher, academics and their students, policy makers, and livestock operators) an up-to-date analysis of the important issues related to salt-rich feedstuffs (nutrition, productivity, and reproduction).

Soil salinity is a key abiotic-stress and poses serious threats to crop yields and quality of produce. Owing to the underlying complexity, conventional breeding programs have met with limited success. Even genetic engineering approaches, via transferring/overexpressing a single ‘direct action gene’ per event did not yield optimal results. Nevertheless, the biotechnological advents in last decade coupled with the availability of genomic sequences of major crops and model plants have opened new vistas for understanding salinity-responses and improving salinity tolerance in important glycophytic crops. Our goal is to summarize these findings for those who wish to understand and target the molecular mechanisms for producing salt-tolerant and high-yielding crops. Through this 2-volume book series, we critically assess the potential venues for imparting salt stress tolerance to major crops in the post-genomic era. Accordingly, perspectives on improving crop salinity tolerance by targeting the sensory, ion-transport and signaling mechanisms were presented in Volume 1. Volume 2 now focuses on the potency of post-genomic era tools that include RNAi, genomic intervention, genome editing and systems biology approaches for producing salt tolerant crops.
