Intsormil- Centa’S New Bmr Sorghum Varieties Create A Surge In Dairy Production, René Clará Valencia
INTSORMIL Scientific Publications
Scientists from the INTSORMIL-CENTA project based at the National Center for Agricultural Technology and Forestry (CENTA) of El Salvador have worked for five years to develop varieties of sorghum for grain and forage that are highly nutritious to cattle. Using the gene bmr-12, received from Dr. Gebisa Ejeta of Purdue University, they combined commercial varieties CENTA S-2, S-3 CENTA, CENTA RCV and VG 146 and were able to form new varieties containing this same gene. The first generation created 76 new varieties.

The returns to the introduction of new photo-insensitive sorghum varieties into the dairy industry were analyzed to determine changes in the welfare of consumers, processors, producers and the society. The economic surplus method was used along with a survey data of a stratified sample of 150 farms conducted in 2011 in El Salvador. Results indicate that there are large returns per dollar spent and substantial benefits to consumers, processors and producers. Results also show that the adoption of these new technologies represents advantages in production costs of milk in each farm size. These cost savings per bottle are very small …

Economic Impact Of Stable Flies (Diptera: Muscidae) On Dairy And Beef Cattle Production, David B. Taylor, Roger D. Moon, Darrell R. Mark
Department of Agricultural Economics: Faculty Publications
Stable flies, Stomoxys calcitrans (L.), are among the most damaging arthropod pests of cattle worldwide. The last estimate of their economic impact on United States cattle production was published 20 yr ago and placed losses at $608 million. Subsequently, several studies of effects of stable flies on beef cattle weight gain and feed efficiency have been published, and stable flies have become increasingly recognized as pests of cattle on pasture and range. We analyzed published studies and developed yield-loss functions to relate stable fly infestation levels to cattle productivity, and then estimated the economic impact of stable flies on cattle …
