Estimated copper requirements of angus and simmental heifers.

In Exp. 1, Simmental (n = 21) and Angus (n = 21) heifers, approximately 9 mo of age, were used in a 160-d study to determine the effect of dietary Cu on growth and Cu status. Two- or three-yr-old first-calf heifers (21 Angus and 21 Simmental) entering into their last trimester of pregnancy were used in Exp.

Evaluation of crossbred calf and cow types for the coastal plain of North Carolina.

Data in this experiment consisted of 418 lactation records, and weaning and birth weight records from 600 crossbred calves. The traits evaluated included birth weight, weaning weight, weaning weight per cow exposed, weaning weight per weight of cow, weaning weight per weight of cow exposed, and predicted milk yield. Angus, Brangus, and Gelbvieh sires were mated to purebred Hereford cows.

Serum antibody responses of cattle to iron-regulated outer membrane proteins of Pasteurella haemolytica A1.

Serum antibody responses to the 70, 77, and 100 kDa iron-regulated outer membrane proteins (IROMPs) of Pasteurella haemolytica A1 were studied in cattle vaccinated with outer membrane protein (OMP) enriched outer membrane fraction, IROMP-enriched outer membrane fraction or live P. haemolytica. Vaccination with an IROMP-enriched outer membrane fraction stimulated antibodies to the 70 kDa IROMP, whereas vaccination with live P.

Psychosexual changes associated with the perimenopausal period.

The perimenopausal period is often a frustrating time for the woman who is experiencing it and for the health care professional who provides care for her. Although menopause is a universal experience for women, how it is experienced is not universal. Physiology, anatomy, social support systems, culture, expectations, and the woman's attitudes (especially her self-image) all have an influence on how easy or difficult the perimenopausal transition period is for an individual.

Personality factors in failure to adapt to the military.

As technical training costs increase in the military, it is increasingly important to identify and eliminate as soon as possible individuals unwilling or unable to adapt to the demands of the military. The present study compares three groups of enlisted personnel below the rank of E-4: a group having adjustment problems but motivated to remain in the military, a group having adjustment problems and seeking a discharge, and a well-adjusted group. Two scales of a personality inventory were found to differentiate the groups and suggest potential value for screening of military applicants.
