The effect of alpha phase morphology on the impact energy of commercial purity titanium

Creator:: York, James Michael
Abstract:: Samples of commercial purity titanium were heat treated above the beta transformation temperature and within the two phase alpha-beta phase field, followed by cooling at varying rates. Testing of the samples in tension and by instrumented impact indicated that some strengthening could be imparted by these heat treatments, although at...

Sheep selection in retrospect

Creator:: Saoud, Nabeel B.
Abstract:: A total of 399 crossbred ewes from two birth years were raised under two management systems, irrigated vs. dryland hill pastures.

Inheritance of maternal antibody concentration in the bovine neonate

Creator:: Muggli, Noelle Elizabeth
Abstract:: Serum samples were collected between 24 and 48 h of age from 408 Hereford calves of a selection experiment and from 200 Angus, Hereford and Red Poll calves of another experimental population (Germ Plasm Utilization project). Concentrations of Immunoglobulin G₁ (IgG₁) were determined by single radial immunodiffusion. Breed or selection...

Sheep breed evaluation : grazing behavior, condition scores and lamb production

Creator:: Berggren-Thomas, Bruce
Abstract:: I. The Effects of Sire Breed, Forage Availability and Weather on the Grazing Behavior of Crossbred Ewes. Thirty nonpregnant, nonlactating crossbred ewes, six per sire breed (Suffolk, Clun Forest, Dorset, Polypay and Border Leicester), were observed grazing together in a 0.87 ha grass-clover pasture for six days over a two-week...

Inheritance of active and passive immune responses in sheep

Creator:: Berggren-Thomas, Priscilla L.
Abstract:: Six hundred sixteen ewes of six strains were inoculated twice with ovalbumin in Fruends' incomplete adjuvant in order to investigate genetic variation in immune response. Blood samples were collected from the ewes 6 days post-second injection. Serum samples were also collected from their 709 lambs, born in June 1984, between...

Population analysis of a commercial beef cattle herd

Creator:: Schons, Debra Jo
Abstract:: Twenty-four years of records (1958-1981) from a commercial Angus ranch were utilized in a population analysis to characterize the herd as a biological unit. The herd averaged 632±129 cows and 123±6 replacement heifers with all replacement heifers and many bulls from within the herd. Life tables were calculated for seven...

Breed and heterosis effects on wool and lamb production of rotationally crossed ewes

Creator:: Gallivan, Catherine Agnes
Abstract:: One thousand twenty-three lambing records of 351 ewes bred in a rotational crossbreeding system involving Columbia or Targhee, Hampshire and Finnish Landrace breeds were examined. A regression approach was used to determine the effects of breeds and heterosis on wool grade, greasy fleece weight, ewe weight at lambing, lambing date,...
