Effects of saponin-containing extracts on fat digestibility, growth, and nutrient availability in domestic fowl

Creator:: Hix, Rebecca J.
Abstract:: Numerous properties of Yucca schidigera and Quillaja saponaria have been studied with respect to the saponins in the plant. These saponins are present in the extract as well and have been utilized commercially in the food and cosmetic industry for various products. Saponins have detergent-like properties in the presence of...

Role of IL-8 and TIMP-2 on term canine trophoblast migration, invasion, and proliferation

Creator:: Gullaba, Justine Marie
Abstract:: Placental pathologies are not uncommon in dogs. For example, in primiparous bitches, the reported incidence of subinvolution of placental sites is 21% - 100%. Despite years of research in multiple species, the mechanisms regulating late gestation trophoblast behavior in the dog remain unexamined. Therefore, the objective of this study was...

Applications of GnRH immunization in domestic dogs

Creator:: Donovan, Caitlin Elizabeth
Abstract:: Reproductive function in the dog is controlled by feedback mechanisms that involve the hypothalamus, the anterior pituitary gland, and the gonads. Surgical gonad removal, a common procedure performed in dogs for the purposes of sterilization, disrupts the hypothalamic-pituitary-gonadal (HPG) axis and results in permanently elevated concentrations of gonadotropins. Manipulation of...

Alpha-tocopherol is a potential diagnostic indicator of metabolic diseases in early lactation dairy cows, α-tocopherol is a potential diagnostic indicator of metabolic diseases in early lactation dairy cows

Creator:: Qu, Yang
Abstract:: Milk fever (MF), retained placenta (RP), and left displaced abomasum (LDA) are three common and costly metabolic diseases in cows during the first days of lactation. Some studies suggest that circulating concentrations of α-tocopherol (ATOC) are decreased by these three diseases. It is, however, unknown if and how long lower...

Effects of differential ewe body condition at mating and early post-mating nutrition on embryo survival

Creator:: West, Kathryn S.
Abstract:: Two trials were conducted over consecutive years to examine the effects of ewe body condition and post-mating nutrition on ovulation rates and embryo survival. Trial 1 used 146 Polypay ewes ranging in age from 5 to 8 years in a 3 x 2 factorial array of pre-mating (high-H, low flushed-LF...

Maternal diet and essential fatty acid metabolism in progeny chickens

Creator:: Bullock, Cheri Jean
Abstract:: During the 21 day incubation period, the fertile egg provides nutrients such as fatty acids for energy and polyunsaturated fatty acids (PUFA) for membrane synthesis to the developing chick. The hypothesis tested in the present study is that the type of PUFA fed to the breeder hen can alter tissue...

Physiological factors affecting ovine uterine estrogen and progesterone receptor concentrations

Creator:: Prater, Patrice L.
Abstract:: Two experiments were conducted to determine whether in ewes uterine concentrations of estrogen and progesterone receptors are affected by the presence of a conceptus or by the hormonal milieu associated with extremes in photoperiod to which ewes are exposed. In Exp.1, nine mature ewes were unilaterally ovariectomized by removing an...

In Vivo and In Vitro effects of a cyclopropenoid fatty acid on progesterone synthesis by the ovine corpus luteum

Creator:: Tumbelaka, Ligaya
Abstract:: Two experiments were conducted to examine the effect of a cyclopropenoid fatty acid on luteal cell function. In Exp. 1, 12 mature ewes were mated to a fertile ram, assigned to two groups (n = 6/group) and laparotomized on day 18 of gestation. Ewes with corpora lutea (CL) in both...

Characterization and cloning of a cDNA encoding an adipocyte-specific membrane protein

Creator:: Killefer, John
Abstract:: The accumulation of excessive fat is a serious concern in both the livestock production and human health fields. Obesity is a condition of excessive energy storage in the form of body fat ( triacylglycerols ). The cellular basis for obesity is not yet understood but numerous factors have been suggested....
