Nutritional influences affecting senecio toxicity in laboratory animals

Creator:: Buckmaster, Gary Wayne
Abstract:: The objective of this research project was to evaluate the toxicity of local pyrrolizidine alkaloid containing plants and to examine the influence of dietary protein, with particular reference to the amino acid cysteine, upon this toxicity. Senecio vulgaris (common groundsel) was shown to be more toxic than Senecio jacobaea (tansy...

Evaluation of wet brewers' grain ensiled with low quality forages

Creator:: Kennedy, Matthew A. (Matthew August)
Abstract:: Two experiments were conducted to evaluate the use of wet brewers' grain (WBG) alone and with straw so it can be used as part of the sole ration for ruminants. In Exp. 1, WBG was ensued alone and was mixed with one of two straws, wheat or tall fescue grass...

Characteristics of preovulatory follicles of pubertal gilts

Creator:: Smith, Gary Daniel
Abstract:: Two experiments were conducted utilizing crossbred gilts to evaluate follicle characteristics at puberty and to determine the effect of exogenous estradio1-17β on embryonic mortality in the mature cycling gilt. Experiment 1 was conducted to compare preovulatory follicle numbers and sizes and follicular fluid concentrations of progesterone, estradio1-17β, plasminogen activator and...

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...

Effects of alpha-linolenic and linoleic acids on timed AI reproductive performance in replacement beef heifers, Effects of α-linolenic and linoleic acids on timed AI reproductive performance in replacement beef heifers

Creator:: Thompson, Emily C.
Abstract:: The objective of this study was to determine if supplementing linoleic or α-linolenic acids, and timing of supplementation around AI will alter supplemental intake, ADG, and serum progesterone (P4), cholesterol, and triglyceride concentrations in replacement Angus crossbred heifers. In yr 1, 54 heifers, stratified by age, were assigned to: barley...

Effects of conjugated linoleic acids on PGE₂, PGF₂α and progesterone production by bovine luteal cells in vitro

Creator:: May, Katherine C. P.
Abstract:: Feeding conjugated linoleic acids (CLA) improves reproductive performance in dairy cows; however, the molecular mechanisms by which CLA improves reproduction are not well understood. Therefore, we evaluated whether the CLA isomers, trans-10, cis-12 CLA and cis-9, trans-11 CLA altered synthesis of steroidogenic hormones in bovine luteal cells by measuring concentrations...

Gonadotropin releasing hormone-induced secretion of luteinizing hormone during the milk ejection reflex in the postpartum beef cow

Creator:: Jaeger, John Ralph
Abstract:: A study was conducted to determine the effect of the milk ejection reflex on exogenous gonadotropin releasing hormone (GnRH)- induced release of luteinizing hormone (LH) after short term calf removal. Twenty-four postpartum multiparous beef cows were assigned 3 randomly to groups arranged in a 2[superscript 3] factorial design to be...
