The effect of selenium on chemical carcinogenicity in the rat

Creator:: Johnston, Weldon Kearney
Abstract:: One hundred and fifty-one weanling rats of both sexes were fed control diets or diets containing 160 ppm diethylnitrosamine (DEN) or 150 ppm N-2-fluorenyl-acetamide (FAA). The carcinogen level was calculated so that the LD₅₀ should be achieved at about 17 weeks. Each carcinogen treatment was incorporated with three different diet...

Genetic components of genetic influence on traits of purebred and crossbred populations of swine of Berkshire and Yorkshire origin

Creator:: Bellatty, Paul T.
Abstract:: Purebred and crossbred litters of Yorkshire and Berkshire breeds of swine were evaluated for number of piglets born alive per litter, number of piglets weaned per litter, mean piglet birth weight, mean piglet birth weight adjusted for number of piglets born alive per litter and mean piglet weaning weight. The...

Membrane-type matrix metalloproteinase and inhibitor expression in sheep embryos and uterus

Creator:: Paul, Katy Beth
Abstract:: Expression of membrane-type matrix metalloproteinases (MT) and tissue inhibitors of matrix metalloproteinases (TIMP) was evaluated in sheep embryos and uterus during the pre- and peri-implantation periods. Embryos and uterine samples were surgically collected from ewes on days 9, 11, 13, and 15 of pregnancy (n=3 ewes/day) and of the estrous...

Concerted actions of ovarian steroids and prostaglandin F₂a on smooth muscle contractility of ovine and bovine uterine arteries

Creator:: Ford, Stephen Paul
Abstract:: The role of estradiol- 17β, progesterone and prostaglandin F₂α (PGF₂α) in altering contractility of uterine vascular smooth muscle was investigated. A segment of uterine artery (3. 5 cm) supplying each uterine horn of ewes and heifers were removed at necropsy and perfused with oxygenated Krebs Henseleit Solution prior to initiating...

Production responses of barrows fed finisher rations with 11 vs 14 percent protein

Creator:: Bellatty, Paul T.
Abstract:: Tests using paired pens of barrows were conducted during a 13 month period to determine the influence of protein level of the ration on production traits of market barrows. One member of each pair of six to ten full- and half-sib pairs was randomly allotted to each pen group; thus,...

Reproductive endocrinology and vaginal cytology of the female llama (lama glama)

Creator:: Leon, Juan B.
Abstract:: Four studies were conducted in the llama (Lama glama) evaluating changes in reproductive physiology, vaginal cytology, and growth. Study I. Temporal changes in vaginal cytology were correlated with alterations in serum estradiol -17β and progesterone concentrations. A 2 * 2 factorial study examined the treatment effects of a) concurrent male...

Studies on luteinizing hormone and gonadal steroids in male and female llamas (Lama glama)

Creator:: Reed, Pamela J.
Abstract:: A series of studies was performed to more clearly evaluate gonadal function in llamas. Luteinizing hormone (LH) and progesterone (P₄) concentrations were compared following natural or hormone-induced ovulation. Luteal regression was evaluated following administration of the prostaglandin F₂α analog cloprostenol. The interaction of age, season and castration on testosterone (T)...

The relationship of blood glucose levels to ovulation rate and early embryonic mortality in gilts

Creator:: Day, Paul E.
Abstract:: A study was made of blood glucose levels and their relationship to reproduction in gilts. Twelve blood samples, two in each of three successive weeks, before and after breeding were taken. Half of the samples were obtained from gilts in a fasting state and half after feeding. All samples were...
