Parameters For Milk Yield And For Percents Of Ash, Dry Matter, Fat And Protein In Sows, W. G. Pond, L. Dale Van Vleck, D. A. Hartman Jan 1962

Parameters For Milk Yield And For Percents Of Ash, Dry Matter, Fat And Protein In Sows, W. G. Pond, L. Dale Van Vleck, D. A. Hartman

Faculty Papers and Publications in Animal Science

Milk was collected separately by machine from four to six glands on nine Yorkshire and Berkshire sows 2 or 3 days after farrowing and at weekly intervals throughout 6 weeks of lactation. Milk yield was measured following intramuscular injection of oxytocin, and the percent of ash, dry matter, fat and protein in the milk from each gland was determined. The average milk yield per gland, following a 1-hour period during which the pigs had been removed from the sow reached a peak of 74.6 gm. 3 weeks after farrowing. The ash content was 0.79% 2 or 3 days ...

Oyster Mortality Studies In Virginia: Ill. Epizootiology Of A Disease Caused By Haplosporidium Costale Wood And Andrews, Jay D. Andrews, Johon L. Wood, H. Dickson Hoese

VIMS Articles

A short, sharp eplzootic disease of oysters on Seaside of Eastern Shore, Virginia, has been associated with a new pathogen, Haplosporidium costale Wood and Andrews. Native oysters in trays have shown closely timed May-June losses for three consecutive years. Losses at other seasons were small. May-June losses ranged from 12 to 14 percent in 1959 to 36 to 44 percent in 1960. James River oysters moved to Seaside showed higher losses than natives after a year of acclimation. Oysters in Bayside creeks revealed late summer losses caused by Dermocystidimn marinmn Mackin, Owens, and Collier rather than May-June deaths.

The Blue Crab And Its Fishery In Chesapeake Bay. Part 2. Types Of Gear For Hard Crab Fishing, W. A. Van Engel Jan 1962

The Blue Crab And Its Fishery In Chesapeake Bay. Part 2. Types Of Gear For Hard Crab Fishing, W. A. Van Engel

VIMS Articles

During the 90-year history of the Chesapeake Bay blue crab fishery, many types of fishing devices were tried, but only pots, trotlines, and dredges proved suitable, and they emerged as the primary types of gear for catching hard crabs. In the early years of the fishery, trotlines with their various modifications were used principally for catching hard crabs in the summer. The Chesapeake Bay crab pot, patented in 1938 and modified only slightly since, gradually replaced the trotline. Pots now account for two-thirds of the Virginia hard crab catch and more than half of the Maryland catch. The dredge, first ...

A Survey Of The Helminth Parasites Of Pheasants From Brown County, South Dakota, Donald E. Gilbertson Jan 1962

A Survey Of The Helminth Parasites Of Pheasants From Brown County, South Dakota, Donald E. Gilbertson

Electronic Theses and Dissertations

This paper presents a study of the helminth endoparasite of the Chinese or ring-necked pheasant (Phasianus colchicus). The digestive and respiratory tracts of 262 pheasants, all of which were collected in Brown County, South Dakota, were examined. Collections were ,made from January, 1961, through November of the same year. The problem was divided as follows: (1) locating and Identifying the helminth parasites, (2) relating parasitism to the age of the birds, (3) ascertaining the seasonal distribution of the parasites, and (4) determining what gross pathological changes were due to parasitism. Previous to this study, little or no literature was available ...
