Evaluation of Level of Milk Potential on Nutrient Balance in 2- and 4- Year- Old May- Calving Range Cows Grazing Sandhills Upland Range

A modeling study evaluated the effects of milk production level on nutrient balance in May- calving cows grazing Sandhills upland range during the breeding season. Forage quality of upland range peaks in June and steadily declines in July until November. With timing of forage quality decline and increasing nutrient demands due to lactation, cows were in a negative energy balance in late June and early July prior to deficiency of metabolizable protein. Supplementation to meet energy deficiencies in June and July and MP deficiencies in July with distiller grains that is high ruminally undegradable protein and high fiber energy may be needed in May- calving cowherds. Selection for milk over 23 lb at peak lactation creates deficiencies early post- calving and increases the need for additional supplementation to correct the nutrient deficiency. In an effort to match cow type to environment in the Sandhills and optimize performance, producers should consider selecting against high milk potential

In a Land of Plenty: A Don West Reader

Rooted in a particular place, the South and especially the Appalachian hills; in a long time, with poems dating from as early as 1932 and as late as 1981; and in the wide experience of a man who has been a farmer, lineman, preacher, organizer, deck hand, professor, and journalist. Land of Plenty is about America over the last half a century. It is about miners, freedom, racism, sharecroppers, family, love, loss, the South, laughter, labor, hunger, and heroism...Constance Adams West\u27s spare illustrations make Land of Plenty still more beautiful. -Dave Roediger, Dept. of History, Northwestern U.https://digitalcommons.lmunet.edu/crfb/1000/thumbnail.jp

Evaluation of Lactation Demands on Nutrient Balance in Two Calving Seasons in Range Cows Grazing Sandhills Upland Range

A modeling study evaluated the effects of milk production level on nutrient balance in March-and May-calving cows grazing Sandhills upland range during the breeding season. Forage quality of upland range peaks in June and steadily declines in July until November. In March-calving cows, metabolizable protein (MP) and energy were deficient by July 1 in all milking potential cows, which is exacerbated in greater milking potential cows. May-calving cows with 20 to 30 lbs of milk are predicted to enter the breeding season with a deficiency in MP and energy. In an effort to match cow type to environment in the Sandhills, producers should be selecting against high milk potential. With timing of forage quality decline and the start of breeding season in July, selecting for moderation in milk production becomes even more important in May-calving herds. Supplementation to meet MP deficiency with high ruminally undegradable protein supplements may be need in later breeding cows and younger cows in both March-and May-herds

Linking Research to Educational Policy and Practice: What Kind of Relationships in How (de)Centralized a Context?

There have been debates on two issues related to the process of improving educational quality. The first concerns the alternative models for the relationship between researchers and policymakers/practitioners in efforts in efforts to link research and policy/practice. The second involves arguments about merits of centralized, linear versus decentralized, iterative strategies for reforming education. In this chapter, we summarize the issues raised in these debates and then explore them using illustrations drawn from documentation research of a USAID-funded project, Improving Educational Quality (IEQ), which operated in Ghana, Guatemala and Mali during the years from 1992 to 1996

Aquaculture and marketing of the Florida Bay Scallop in Crystal River, Florida

The overall goal of this study was to develop a new fishery resource product through open-water aquaculture for the west coast of Florida that would compete as a non-traditional product through market development. Specific objectives were as follows: I. To grow a minimum of 50, 000 juvenile scallops to a minimum market size of40 mm in a cage and float system in the off-shore waters of Crystal River, Florida. 2. To determine the growth rate, survival, and time to market size for the individuals in this system and area to other similar projects like Virginia. 3. To introduce local fishermen and the aquaculture students at Crystal River High School to the hatchery, nursery, and grow-out techniques. 4. To determine the economic and financial characteristics of bay scallop culture in Florida and assess the sensitivity of projected costs and earnings to changes in key technical, managerial, and market related parameters. 5. To determine the market acceptability and necessary marketing strategy for whole bay scallop product in Florida. (PDF has 99 pages.
