Pastured cows had fewer clinical cases of mastitis, lower body condition scores, and lower body weights than confinement cows, and Holsteins were less likely to rebreed, had moremastitis, higher culling rates, and higher body condition Scores than Jerseys.
Milk production and economic measures in confinement or pasture systems using seasonally calved Holstein and Jersey cows.

Milk production was lower in this study for pasture-based systems but lower feed costs, lower culling costs, and other economic factors indicate that pasture- based systems can be competitive with confinement systems.
Structure-activity studies on sulfamate sweeteners.

- 1 July 1976
The structure-activity relationships governing sulfamate sweeteners are reviewed, and the B center of the Shallenberger A-H,B theory of sweetness is best regarded as being -SO3- rather than -SO2- for sulfamates.

The statistical technique of linear discriminant analysis was applied to the complete set of 33 compounds and to a reduced set of 27 compounds and yielded correct classifications of 27 and 28 compounds.
Determination of the nonnutritive sweetener sodium cyclopentylsulfamate and three of its metabolites, cyclopentylamine, cyclopentanone, and cyclopentanol, in urine of rats and rabbits.
- G. A. Benson, W. J. Spillane
- ChemistryJournal of Pharmacy and Science
- 1 December 1976
The nonnutritive sweetener sodium cyclopentylsulfamate was fed to Wistar albino rats and New Zealand White rabbits and Assayed by hydrolysis in acidified dioxane-water and subsequent measurement of the absorbance of the product formed by the liberated amine with p-benzoquinone.
Effects of feeding strategy on milk production, reproduction, pasture utilization, and economics of autumn-calving dairy cows in eastern North Carolina.

The greater stocking rate resulted in increased productivity and greater income over feed costs per unit of land, and breed differences were observed; conception rates at first and all services, as well as pregnancy rates, were greater for Jersey and crossbred cows compared with Holsteins.
