Flow cytometric evaluation of spermatozoan nuclear chromatin structure and viability

Creator:: Ballachey, Brenda Elizabeth
Abstract:: I. Frozen bovine semen samples were measured by flow cytometry (FCM) to determine if FCM analyses could be useful for sperm quality evaluation and prediction of bull fertility. Fluorescent dyes utilized were acridine orange, to measure sperm nuclear chromatin heterogeneity by quantifying susceptibility of the chromatin to denaturation, and rhodamine...

The effects of morphine and naloxone on serum levels of luteinizing hormone in intact and ovariectomized pony mares during the breeding and nonbreeding seasons

Creator:: Dietz, Jane F.
Abstract:: Intact and ovariectomized (OVX) pony mares were randomly assigned to treatments of morphine (M), naloxone (N), or a saline control (C) to determine if endogenous opioid peptides (EOP) play a role in equine seasonal breeding. Morphine was expected to decrease luteinizing hormone (LH), whereas N (an opiate antagonist) should in...

Hypervitaminosis A : effects on reproduction and interactions with pyrrolizidine alkaloids

Creator:: Moghaddam, Mehran Fallah
Abstract:: In the first experiment the minimum dietary toxic levels of vitamin A were determined in pregnant rabbits over three parities. The treatments consisted of basal diet plus 10,000, 30,000, 60,000, and 90,000 IU/Kg added vitamin A. The basal diet was formulated to be free of vitamin A and beta-carotene; rice...

Effects of two forms of intrareticular selenium supplements on beef cow selenium status and on the transfer of selenium from dam to offspring

Creator:: Campbell, Donald T.
Abstract:: Two concurrent studies were conducted to evaluate the effect of selenium (Se) supplementation on beef cows. Trial 1 was designed to evaluate the safety and efficacy of two intrareticular Se supplementation delivery systems. Trial 2 was designed to evaluate the transfer of Se across the placenta and through the colostrum...

The effect of lasalocid on fall calving beef cows

Creator:: Hopman, Bruce T.
Abstract:: Forty-two fall-calving crossbred cows were equally allotted to six pens of seven cow-calf pairs each. Two treatments (0 and 200 mg lasalocid/head/day) with three replications were used to determine the effects of lasalocid on fall-calving beef cows. The cows were fed grass hay, haylage and pasture ad libitum. The cow-calf...
